Requirements for the payment of medicare claims-a selection of some important criteria. It is meant to build a practical awareness of ambulatory (outpatient) clinic operations, not as an exhaustive manual. The core elements of establishing a practice, promoting access for patients to your services, retaining patients and referral sources, and sustaining financial viability are discussed. Too many medical students and residents graduate with high honors and a list of academic achievements, but fail in their careers because of a lack ofbasic business savvy. A full business education is simply too vast to include in the educational journey of a medical school and residency, and this chapter outlines the core skills required to successfully manage a clinical practice and a practical understanding of ambulatory (outpatient) operations. Key Resource inserts are included that lead to more extensive sources of information on each subject. Management is one area where the art to medical science comes into play; it requires a significant time investment and is the area most likely to provide a return on investment than any other aspect of clinic management People make the business. From the provider and their staff to the patients and their families, having the right people on the team will make all the difference. Whether a physician is in private practice or joins the faculty of a large academic medical center, their role in clinic is inherently that of a leader. The physician sets the tone for a practice, and support staff will revere and respect a physician who is a good leader. What good news for the ego, but the responsibility that comes with this role cannot be underestimated. Leadership is refined with experience and does not come naturally to every medical school graduate. It is worth the time and energy for physicians to hone their leadership skills and work towards greatness in this regard. Top leaders are "differentiated from other levels of leaders in that they have a wonderful blend of personal humility combined with extraordinary professional will. Beyond the physician, the people supporting their provision of care carry tone and culture throughout the practice. Relationships between the physician and patient are pivotal, but the amount of time patients spend interacting with the clinic staff far outweighs time spent with their physician. A positive patient care experience hinges on whether each team member they interact with consistently demonstrates helpfulness and kindness and promotes an environment of safety, security, and confidentiality. Hiring staff who subscribe to common philosophies on customer 3332 Chapter 201: Clinic Management 3333 service and priorities in the workplace forms the foundational stability for a thriving. In addition to hiring the right people for the right roles, it is important to rightsize the number of employees. There are several organizations in the market that offer benchmarking data for staffing levels. Physicians are inherently committed to treating patients who come to them in need of care. In the current system, the cost of health care often exceeds individual affordability. While many Americans have insurance coverage, there are a vast number of individuals and families who do not. There are also people with high deductible insurance plans who, while covered by an insurance plan, will struggle with affordability. Health care providers must balance both missions: to provide care to those in need, while remaining viable as a business and able to sustain continued services over the course of time. One method used to promote sustainability is to divide a portion of patient appointment slots between various payer classes. This mechanism builds in both the accommodation of patients with a variety of payment sources as well as the funding from enough insured patients to sustain the practice. Requests for physician services come from a variety of constituents: referring primary care doctors, referring specialists, their office staff. To accommodate all requests, it is advisable to develop policies and consistent protocols around both who is authorized to refer a patient to the clinic and what process they must follow to do so. Labs or other ancillary test results from outside sources will avoid ordering duplicate studies or tests and achieve a continuum of care for the patient. Such policies must be built in advance and adhered to consistently in order to ensure equity in access. Another consideration in access points is how requests are received-whether by inbound phone, fax, e-mail, or other mechanisms, a quick turnaround and bidirectional communication with the requester is important to promote access and survive in a competitive market. Acquiring a reputation of being difficult to access or slow to respond to appointment requests will quickly drive referring physicians to send their patients elsewhere. It impacts not only revenue but also clinic throughput efficiency; staff morale, and patient satisfaction. Length of appointment will naturally vary by provider, but a good rule of thumb Several health care management organizations exist for benchmarking and idea sharing: to name a few, the Medical Group Managers Association, Healthcare Financial Management Association, Healthcare Information and Management Systems Society, American College of Healthcare Executives, and many more that dive deeper into specialties or delineate between academic medicine and private practices. Retention of excellent employees saves a practice both time and money and improves the quality of care. Patient care can suffer when the nursing and administrative staff members are inexperienced or unfamiliar with the clinic operations. Beyond just being a great leader and setting a productive cultural tone, there are tactical strategies to retain good people. Paying market-competitive salaries that keep pace with inflation and offering a competitive benefits package to supplement take-home pay are strategies. Retention is not a mystery-consider what drives each individual on your team and ensure that his or her intrinsic needs to be a happy and productive employee are met. The template can be adjusted accordingly to properly account for a typical new or established patient visit with each provider. There are several examples of template design techniques that can be used to promote access, the most common include · Stream scheduling: Patients are each given a unique appointment time and arrive in a steady stream throughout clinic. This technique works well for brief visit types and when clinic staffing levels are flexible to accommodate variations in demand. This works best for patients whose needs can be met simultaneously, for example, patient A requires lab work and will have a wait time while results are processed, during which the physician can see patient B for suture removal. Double booking is also used where patient populations have a high rate of no shows or lastminute cancellations, in order to ensure a full schedule despite last-minute decline in patient demand. This is useful if the patient care involves a particular piece of equipment and efficiencies are gained by seeing patients back to back. In wave or modified wave, the appropriate triage of patient needs when scheduling the appointments is critical to success. Once an appointment is scheduled, the process to obtain approval for any procedures should begin immediately. The difficulty for physicians in this system is that each insurance company typically develops a unique set of rules around which procedures require an authorization, the process physicians must follow to obtain pre-approval, and even the level of detail or data sets required to obtaining an authorization. The best approach is to have dedicated office personnel for this function who can become familiar with each of the rule sets, keep abreast as they change, and allow as much time as possible to follow their protocols before a service is rendered. This information must be accurately captured to process medical claims or advance their account through the collections cycles for payments due after the date of service. Many insurance companies provide eligibility verification tools on their Web sites, or there are clearinghouse vendors whose technology will automatically validate discreet data fields against various insurance company databases to guide correction of inaccuracies. For example, documentation that is thorough and detailed takes time, as does visiting with a patient during a routine evaluation and management visit. The challenge for physicians is to find balance and work towards efficiency, trimming any wasted time from the day. Clinic layout and flow is one way to save steps for physicians, nurses, and other support staff. It is important to have the right number of support staff, but each one must have the ability to do his or her job efficiently and without, or at least with minimal, waste. For example, to run two exam rooms in parallel, the vitals station must be set up to filter patients through from the waiting area to exam room in a timely manner. Having a vitals space that is in an awkward location or having too few staff to support patient movement through the hallways can result in exam rooms sitting vacant for periods of time or worse sitting idle with waiting patients inside. Flow diagrams, Pareto charts, spaghetti diagrams, and process time studies are all excellent continuous quality improvement tools available to help troubleshoot clinic flow issues. It will be obvious that there is a problem; the difficulty comes with identifying the root cause and implementing and monitoring the fix. Successful improvement initiatives begin with a clear goal and an understanding of the information needed to identify and monitor measures of resolution. The problem we face, therefore, is not a data problem, it is an information problem" (5). Clinic operations management is complex: in that it requires standardization Chapter 201: Clinic Management 3335 and structure, while remaining flexible enough to adapt as the regulatory, technologic. Identify key opinion leaders who will more readily shift from neutral to supportive and allow their influence to drive peers who are resistant from their state of resistance to one of neutrality. Third, actively listen to concerns and address them consistently and persistently, allowing emotional reactions to change to subside under the limelight of good information. Even with extensive planning and communication, there will remain those who simply will not accept change. As a change leader, be mindful that late adopters can easily drain time and resources. Identify late adopters early on and have a plan in place to address their resistance without sacrificing support for the adoptive group. Instead people should be looking for the multiple contributing factors, which can be resolved only by improving systems" (7). In the process of contracting, one key negotiation is the amount agreed to accept as payment in full, also called the allowable. The application of safety-oriented research is incredibly important to health care. However, the benefits of standardization where applicable ensure quality and serve to reduce medical errors. Clinic support staff must feel comfortable bringing forward matters they believe to be potential quality or safety issues. They need an open, safe forum for passing this information up to the management or physician team to proactively address. Many organizations provide an anonymous mechanism to promote honest open feedback and solicit input from those who are on the front lines and therefore more likely to notice potential safety land mines. The response when a medical error or safety breach does occur is also a key indicator of the culture. Health Overview of Negotiation Goals Provider goals in a negotiation: Insurance company goals in a negotiation: Maximize payment per service Minimize payment per service provided provided Minimize authorization Utilization review-control requirements for procedures, procedure volumes, limit to autonomy in decision-making medical necessity only for medical necessity Minimize administrative burden in claims adjudication (file claims and receive payments electronically, etc. Once the contract is signed, your role in the relationship must remain proactive and continuous. Specifically, close monitoring of claims payments over time to assess whether payers are complying with the terms and agreed upon rates. Several tools in the marketplace have the capacity to electronically scrub or analyze claims payment data and identify under- and overpayments. It is likely there will be errors in payment as systems on both the insurer and provider side are complicated and interwoven. Expecting payment terms to be met without constant monitoring is overly optimistic. This Web site contains up-to-date information for physicians on repayment for care of Medicare beneficiaries. Despite national recognition of the need to revolutionize how much our nation is spending on health care, as of 2011, the payment methodology used to reimburse physicians for their time and expertise is based on the volume of services provided. Pay for performance and value-based purchasing are new buzz words to the reimbursement scene in the early 2000s and are each an attempt to tie in quality of care in addition to volume. The idea being, rather than paying providers simply for a specific service, payers would reimburse providers based on their clinical outcomes or on measurable indicators of effective health care services. These systems are imperfect and exist in a variety of pilot modes across the country, but they are driving providers to pay attention to quality measures and patient population management strategies in addition to daily clinic operations. Whether or not our industry adopts these models, it is generally agreed across political platforms that the current model in the United States is unsustainable. Health care financing is convoluted and has evolved over time into a difficult to understand stratosphere of funds flows. The process to determine financial responsibility and pursue payment takes time, introducing days of lag between the point when a service is rendered and when it is fully paid for by either the insurance agent or patient. There are several methods to do so, but most effective is to attempt to collect the patient portion of payment on the day of their office visit. This point of service opportunity allows the provider to make decisions about their willingness to see patients who are in debt for prior services or unwilling to resolve those balances in a timely manner. It is also a key time to educate patients about their expected out-of-pocket expense, and patients may need to make decisions about the services they receive when care is optional. Estimating the actual out-of-pocket expense for any visit is a challenge since information around the full complement of services that will be provided to a specific patient are often undefined until after a patient needs assessment is complete. Estimating as accurately as possible and practicing consistent policies for services rendered before, aftet; or regardless of payment is critical to establish.

Lesions often appear first on the trunk and spread peripherally in a symmetric fashion with dependent areas such as the lower extremities manifesting purpura antifungal cream boots discount grifulvin v express. Lesions clear with withdrawal of the causative agent but may progress to a generalized exfoliative dermatitis if the drug is continued antifungal nail paint buy cheap grifulvin v. Lesions may fade following drug cessation or resolve with a residuum of postinflamrnatory hyperpigmentation fungus gnats windex order generic grifulvin v from india. One unusual cause is the lymphocyte recovery state in patients receiving chemotherapeutic drugs for leukemia and lymphoma following the nadir of their peripheral lymphocyte counts fungus gnats in miracle gro potting mix buy grifulvin v 125 mg on line. It has been suggested that neutrophils in the papillary dermis or in the lower levels of the epidermis are seen in a third of cases fungus gnat trap purchase grifulvin v online now,33 but this has not been our experience. Some examples, particularly the scarlatiniform eruptions, may show no epithelial alterations. Differential Diagnosis Viral exanthemata and erythema multiforme reactions closely mimic exanthematous drug eruptions. Tissue eosinophilia is unusual in the former two entities, except in the context of erythema multiforme-like drug reactions. One example is hemolytic anemia associated with methyldopa, mediated by the induction of autoantibodies directed against red blood cell antigens; another is autoimmune thrombocytopenic purpura, mediated through antibodies against platelets and provoked by pyrazolone derivatives (eg, phenylbutazone and allopurinol), sulfonamides, penicillin, salicylates, thiazides, diuretics, and chloramphenicol. The latter leads to the recruitment of a subset of skin-seeking T lymphocytes that attach to high endothelial venules via interaction between lymphocyte function antigens and their respective endothelial receptors. The sensitized lymphocytes then migrate to the peripheral lymph nodes, where proliferation of memory and effector cells occurs. The circulating effector lymphocytes return to sites of cutaneous sensitization via homing receptors for tissue-specific endothelial ligands. Acute graft-versus-host disease, although it should be easily excluded by clinical history. Resolution following cessation of therapy is slow, with postinfiammatory pigmentation being more pronounced than in idiopathic lichen planus and being particularly noteworthy in dark-skinned patients. Not every patient experiences resolution even after cessation of the causative cl. Eosinophils and plasma cells frequently are present as is deep extension not typically seen in. A vacuolar lymphocytic interface dermatitis is associated with a superficial perivascular lymphohistiocytic, and eosinophilic infiltrate. The baseline histology is one of a lichenoid purpuric dermatosis but with accompanying granulomatous features. Eosinophils and parakeratosis, common in lichenoid drug eruptions, are rare in lichen planus, as is middle o. Clinically, lesions are more widespread in lichenoid drug eruptions versus the more prominent localization to fie:mral surfaces of wrists and ankles, the lumbar region, and mucosae in the idiopathic form. Hypertrophic lichen planus, seen classically on the shins, represents a form of localized hypersensitivity reaction with superimposed prurigo nodularis effects and manifests tissue eosinophilia. Lesions of secondary syphilis may manifest a bandlike mononuclear cell infiltrate and not all contain significant numbers of plasma cells, Fixed drug eruption Clinical Features Fixed drug eruptions (Table 12-6), first described by Brocq in 1894, are now associated with the long list of drugs shown in Table 12-7. The acute lesion, a sharply circumscribed round or oval patch of violaceous or dusky erythema, generally arises within 30 minutes to several hours following drug administration. The oral-genital fixed drug eruptions often due to naproxen, tetracyclines, or trimethoprim-sulfamethoxasole, tend to generate lesions on the dorswn of the tongue and, in males, the glans penis. Lesions are often symptomatic by virtue of itching and/or burning and may progress to scaling or retolve with striking postinflammatory pigmentary alteration. Wedge-shaped hypergranulosis overlying an ac:anthotic epidermis with a lichenoid lymphocytic infiltrate. Graft-versus-host disease and viral exanthemata are usually paucl-inflammatory and lack granulocytes. Sweet syndrome, which also can be triggered by drugs such as proton pump inhibitors. A lymphocytic interface dermatitis is present, showing focal accentuation at 1ips of re1ia associated with colloid body formation and a dermal, perivascular, and bandlike lymphocytic and eosinophilic infiltrate. More pronounced epidermal necrosis and colloid body fonnation are seen, and a bandlike dermal lymphocytic and eosinophilic infihrate associated with pigment incontinence. Similar histopathology can incidentally be seen in autoimmune progesterone dermatitis. In phototoxic reactions, the drug absorbs radiation and enters an excited state, producing species that react with other cellular constituents, including reactive oxygen species. In photoallergic reactions, the drug is converted into an immunologically active compound. Phototoxic eruptions characteristically occur within S to 20 hours of first exposure to a drug and resemble an exaggerated sunburn reaction, being characterized by erythema with blistering, vesiculation, desquamation, and hyperpigmentation of sunexposed skin. Most drugs associated with photoallergy, if given in sufficient quantities, can induce a phototoxic reaction. Parakeratosis may sunnount areas of epithelial injury, the patterns of which include apoptosis and reticular degeneration. There is a variable perivascular mononuclear cell-predominant infiltrate that is accentuated around the superficial vascular plexus and manifests exocytosis. Blood vessels usually are dilated and show endothelial swelling or necrosis that diminishes in the depths of the biopsy and is accompanied by hemorrhage. Some patients develop persistent photosensitivity at exposed and nonexposed skin sites. If accompanied by skin infiltration by transformed lymphocytes, the designation chronic photosensitivity dermatitis may be appropriate. Differential Diagnosis of the chronic photosensitivity dermatitides including actinic reticuloid from mycosis fungoides. Pustular eruptions Clinical Features Subacute and chronic dermatitides of diverse causes mimic photoallergic eruptions but generally lack the scattered epidermal cytoid bodies and vascular alterations of phototoxic states and the photoadaptive changes in melanocytes. While the pustules are predominated by neutrophils, eosinophils are often present. An accompanying leukocytoclastic vasculitis may be seen but is not typical in our experience. While the lesions are always described clinically as being nonfollicular, some degree of follicular inflammation can be seen and in fact in some cases the eruption clinically and histologically can be purely follicular based. Cytoid bodies are present along the basal layer, in suprabasilar epidermis, and in Ute cornified layer. Ectasia of superlicial blood vessels, associated with endothelial swelling, is a characteristic. Hypergranulosis, hypericeratosis, and acanthosis are seen, and a plump photoactivated melanocyte is present in Ute basal layer. Spongiform pustulation involving a hair follicle is accompanied by a subcorneal pustule in the adjacent interfollicular epidermis and a perivascular and diffuse dermal infiltrate of lymphocytes and eosinophils. A leukocytoclastic vasculitis is not seen in lesions of psoriasis, except in the setting of concomitant hypersensitivity reactions, such as due to drugs. When a psoriasiform diathesis is seen in concert with a leukocytoclastic vasculitis, Reiter disease merits strong consideration. Amicrobial pustulosis of the folds mimics subcorneal pustular dermatosis but perhaps shows smaller subcomeal neutrophilic abscesses than the iake of pus" seen with the latter. Blistering drug eruptions the blistering drug eruptions include pseudoporphyria cutanea tarda, bullous erythema multiforme, bullous fixed drug eruption, and drug-induced pemphigus, pemphigoid, and linear IgA dermatosis. Eczematous drug reactions Clinical Features Drug-induced pemphigus Clinical Features and Pathogenesis In idiopathic pemphigus, autoantibodies are directed at antigenic targets that include a 130-kDa glycoprotein complexed to an 85-kDa cytoplasmic plaque protein called plakoglobin to form the adhesion molecule desmoglein 3 in pemphigus vulgaris and a 165-kDa cell adhesion molecule termed desmoglein 1 in pemphigus foliaceus. Drug-induced blistering eruptions may present as a superficial pemphigus state, as grouped annular plaques mimicking pemphigus herpetiformis, or with a picture cognate to pemphigus vulgaris. A preblistering prodrome, either a morbilliform or an urticarial eruption similar to a morbilliform or urticarial drug rash, helps to distinguish drug-induced from idiopathic pemphigus. The main agents implicated include those that contain a thiol (sulfhydryl) group, such as angiotensin-converting enzyme inhibitors, penicillamine, and gold sodium thiomalate, and nonthiol drugs such as penicillin and its derivatives, cephalosporins, pyrazolone derivatives such as phenylbutazone, and miscellaneous drugs. It is postulated that sulfhydryl groups of offending drugs bind to the disulfide bond-rich intercellular junctions and either interfere directly with intercellular dyshesion through the mechanical effects of the drug directly binding with intercellular proteins and/or rendering them antigenic. The drug-induced autoantibodies have similar specificities to those seen in idiopathic pemphigus. One study examined 17 Japanese patients with druginduced a pemphigus whereby 8 of the 17 patients demonstrated pemphigus foliaceus-like appearance, 3 showed a pemphigus herpetiformis-lik. Responsible drugs were thiol-containing drugs in all but 1 patient with the main drugs being bucillamine and d-penicillamine. Affected sites frequently correspond to those involved in a prior contact dermatitis, with symptoms arising 2 to 24 hours after an oral dose. The term "baboon syndrome" has been used to describe bright-red, well-demarcated anogenital lesions associated with a symmetric eczematous eruption involving elbow flexures, axillae, eyelids, and the sides of the neck. An alternative designation is one of symmetric drug-related intertriginous and flexural drug-induced exanthoma. The histopathology still resembles linear IgA disease despite a clinical presentation being in the context of one associated with extensive skin sloughing. The fully evolved blistering lesions are identical to their idiopathic counterparts (ie, superficial pemphigus, pemphigus vulgaris, or subcomeal pustular dermatosis). The majority of cases of drug-induced pemphigus, especially those unassociated with pemphigus antibodies, exhibit a pemphigus foliaceus pattern clinically and histologically. M in a distribution that does not reliably correlate with antibody specificity or pemphigus subtype. In patients where the etiologic basis of drug-induced pemphigus is antibody mediated, some 70% of patients have circulating antibodies by indirect immunotluorescence testing. Immuno-ultrastructural localization shows the IgA deposition to be variably in the lamina lucida or hemidesmosomal plaques and adjacent lamina lucida, below the lamina densa, or on both sides of the lamina densa. The latter finding may explain the clinical overlap between the 2 conditions from the standpoint of cicatricial mucosal involvement. In 1994, Nasberger and coworkers reported that antilactoferrin antibodies of IgG and IgM isotype were identified in 5% and 10% of systemic lupus erythematosus patients, respectively, while all patients with hydralazine-induced systemic lupus erythematosus had antibodies of both isotypes with a rapid decrement in the antibody levels following drug withdrawal. Drug-induced dennatomyositis Certain drugs can cause dermatomyositis-namely, lipidlowering agents and antifungal drugs. The greatest literature precedent is in regards to statin-induced dermatomyositis. We had reported a patient who developed a photodistributed rash with muscle weakness within a few weeks of starting the drug terbinafine. It is important to remember that the autoimmune reaction can persist despite drug cessation. A lymphocytic interface dermatitis is associated with epidermal atrophy, vacuolar basal-layer degeneration, cytoid body formation, and suprabasilar lymphocytic satellitosis around degenerating keratinocytes. Epithelial infiltration is frequently only mild and is of maximal intensity in suprapap. A bandlike dermal lymphocytic infiltrate is present and shows haphazard epidermottopism with minimal spongiosis; in other areas not shown, the epidermis was spared, unlike mycosis fungoides, where epidermal involvement is continuous in shave biopsy specimens. Although virtually any drug may induce alopecia, only a few are associated routinely with hair loss. Exacerbation of hair loss with reexposure and hair recovery following withdrawal are the best evidence to incriminate a specific drug. Other drugs associated with diffuse hair loss through unclear mechanisms include naproxen, colchicine, thiamphenicol, amiodarone, levodopa, anticonvulsants, and estrogen therapy following withdrawal. Differential Diagnosis Distinction of drug-induced alopecia from idiopathic anagen and telogen effluvium may be impossible. The lichenoid infiltrate provoked by quinidine mimics lichen planopilaris but lacks hypergranulosis of the interfollicular epidermis and may manifest eosinophilic infiltrates. A perivascular and transmural infiltrate of mature and transformed lymphocytes is present and is unaccompanied by vascular fibrin deposition. Other discriminating features from lymphomatoid papulosis include the relative superficial confinement of the vascular reaction and sparing of inflammation around nerves and the eccrine coil. Among the drugs that can induce cutaneous sclerosis are bromocriptine, lithium, valproic add, hydantoins, b-interferon, hydrm:yurea, and L-tryptophan. With respect to pathobiology, the ergot derivatives provoke peripheral vasoconstriction that damages capillary endothelium. In patients who develop fibrosing reactions in the setting of radiation treatment for various malignant tumors, one must also be cognizant that at times the fibrosing reaction may not be directly related to the radiation per se but could be specifically attributable to the drug best exemplified by the lower extremity bilateral sclerosing reactions seen with pemetrexed. The histology shows a fibrosing reaction associated with a perivascular T-cell-rich infiltrate. Imaging studies will show a fibrosing response involving the skin, fascia, and muscle. The elevation of certain interleukins elaborated by T cells-namely, interleukin 4 and 6-could potentially contribute to the fibrosing reaction. Similar scleroderma-like changes have also b~ described with other drugs, including the taxanes, bleomycin, and gemcitabine. Causes of the former include anticoagulants, lithium, and boric add, Histopathologic Features Sclerodermoid tissue reactions demonstrate widened collagen fibers with diminished fibrillar striations and interstitial infiltrates oflymphocytes and plasma cells. Other alterations of collagen and elastic fibers associated with drug therapy Cutis laxa, anetoderma, elastosis perforans serpiginosa, and pseudoxanthoma elasticum, the clinical and histopathologic features and differential diagnosis of which are considered elsewhere, can be provoked by drugs1. Side effects of chemotherapeutic agents Cfinical Features Chemotherapy-induced reactions include acral erythema characterized by erythema and swelling of the hands after administration of fiuorouracil, Tuol, doxorubidn, methotrente, and arabinoside1·168. There are scattered cytoid bodies within the epidermis that appear concentrated in the acrosyringia as confirmed in deeper levels. Neutrophilic eccrine hidradenitis may be a manifestation of the administration of other drugs, such as lithium,175 or of id reactions to microbial pathogens.

New diseaseassociated mutations are also being identified that will potentially provide new approaches to disease classification and tar geted treatment. Currently, whole exome/genome approaches are not cost effective in most health economies and remain research tools. The infor matics infrastructure needed to analyse the huge datasets generated is also only partly developed. They are also proving valuable for the diagnosis of constitu tional bone marrow failure syndromes. Automated detection of fluorescent signals is followed by computer analysis of the results, which can be either supervised or unsupervised. For example, large Bcell lymphomas were found to fall into two or three different classes that differed in prognosis Other molecular genetic techniques Other molecular genetic techniques are rarely used in routine diagnosis but have research uses. In polyclonal populations of lympho cytes there are a large number of different rearrangements and no single discrete band can be visualized. In a clonal population, since all the cells share the same rearrangement, there is a single dis crete band on electrophoresis, which is separate from the germline band. In clonal populations, there is amplifica tion of a single rearranged fragment, which appears as a discrete band separate from the germline band on electrophoresis. Knowledge of such mechanisms in Tcell maturation is much less advanced than it is for the Bcell lineage. Basic understanding of the somatic mutation processes underlying affinity maturation of immunoglobulin molecules, which occur within germinal centres, allows distinction between lymphomas derived from pregerminal centre, germinal centre and postgerminal centre lymphoid cells. The application of molecular genetic techniques in the investigation of leukaemia and lymphoma Molecular genetic techniques have two principal applications in the investigation of haematological neoplasms. Firstly, they can be used to demonstrate that a monoclonal population is present and can give information on the nature of the lymphoid cell in which a mutation occurred (see later). During rearrange ment single V, D and J regions are combined with a constant (C) region and simultaneously nucleotides (known as N) are added and removed between the V, D and J regions. Problems and pitfalls the polymerase chain reaction is sensitive for detecting small clonal populations but will not detect all rearrangements. The negative results in follicular and certain other lymphomas are consequent on the high rate of somatic muta tion, which is responsible for a failure of consensus primers to bind to rearranged genes [60]. However, this technique is only applicable if the breakpoint occurs in a relatively constant position and the fusion gene is not too long. However it should be noted that, using these sensitive techniques, fusion genes char acteristic of leukaemia or lymphoma are sometimes detected in normal tissues or tissues showing only reactive changes. For example, the rearrangement characteristic of follicular lymphoma has been detected in tonsils removed surgically for reactive conditions. Detection of leukaemia/lymphoma associated fusion genes As discussed earlier, many haematological neo plasms are associated with a specific nonrandom chromosomal abnormality. The genes involved in many of these rearrangements have been identi fied, permitting the use of molecular genetic tech niques for their detection. This is because of the necessity for a chromosomal abnor mality to have been fully characterized so that spe cific primers for each breakpoint can be designed. It should also be noted that, in contrast to standard cytogenetic analysis, molecular genetic techniques permit the detection only of those abnormalities that are being specifically sought. Ultrastructural examination Ultrastructural examination, in which the structure of cells is studied by electron microscopy, can be applied to peripheral blood and bone marrow but is little used in routine diagnostic haematology. Ultrastructural examination can also be applied to trephine biopsy specimens but it is rarely neces sary for diagnosis. Shortterm culture the major current use of shortterm culture in clin ical practice is for assessment of harvested bone marrow or peripheral blood stem cells prior to their use for engraftment. The starting cells are seeded at a sufficiently low concentration that individual colonies localized around each single multipoten tial parent cell can be visualized separately from any neighbouring colonies. The colonies can then be counted at low power magnification by standard light microscopy. Occasionally, the erythropoietic potential of primitive haemopoietic cells requires assessment. Erythroid colonies are readily seen by light microscopy because of the orange/red colour of their cytoplas mic haemoglobin. Apart from the use of culture systems as assays for predicting haemopoietic function in transplan tation, spontaneous colony formation. This potential for falseposi tive results and a relatively high falsenegative rate in true cases of essential thrombocythaemia and polycythaemia vera, together with the cum bersome nature of the assays, has limited the diag nostic application of shortterm colonyforming assays. Longterm culture Longterm cultures, in which haemopoietic precur sor cells are seeded onto layers of pregrown mar row stroma, can potentially permit assessment of the activity of stem cells even more primitive than those that survive in shortterm cultures. Assay of seeded cells is achieved, once they have adhered to the stroma, by replacing liquid medium with methylcellulose or agarcontaining semisolid medium and assessing colony formation as above. It is mainly employed in research, despite its possible value in predicting engraftment. Longterm cultures have also been used for ex vivo purging and expansion of haemopoietic cells for engraftment but these approaches have yet to find widespread clinical application. Bone marrow culture for microorganisms Bone marrow culture for microorganisms, for example mycobacteria, Leishmania donovani or Histoplasma capsulatum, can be of use in diagnosis and will be discussed in the next chapter. A study of hairy cell leukemia and mantle cell lym phoma involvement of the bone marrow trephine specimen by histologic, immunohistochemical, and polymerase chain reaction techniques. The response differs according to whether the infection is bacterial, rickettsial, viral or fungal. The periph eral blood and bone marrow responses to infection are nonspecific and similar changes occur in many other conditions, including trauma and other tissue damage, administration of growth factors, carcinoma, Hodgkin lymphoma, nonHodgkin lymphoma and autoimmune disorders such as systemic lupus erythematosus. Only a minority of patients with an infection show peripheral blood or bone marrow changes suggestive of a particular microorganism. The neutrophils usually show toxic granulation and sometimes Döhle bodies and cytoplasmic vacuolation. Some bacterial infections, specifically typhoid, paratyphoid, tularaemia and brucellosis, are characterized by neutropenia rather than neu trophilia. Typhoid fever can also cause monocyto sis, left shift and toxic changes in neutrophils, thrombocytopenia, anaemia, bicytopenia or pancy topenia; occasionally there are circulating phago cytic cells [1]. Invasive meningococcal infection can be associated with apoptosis of neutrophils and lymphocytes, neutropenia and the presence of cocci within neutrophils, all these correlating with the severity of infection [2]. In severe infection, particularly if there is shock or hypoxia, nucleated red blood cells may appear in the blood, the presence of both granulocyte precursors and nucleated red cells being referred to as leucoerythroblastosis. The lymphocyte count is reduced but a few atypical lymphocytes, including plasmacytoid lymphocytes, may be present; plasma cells are sometimes seen. The eosinophil count is reduced during acute infection but eosinophilia can occur during recovery. Children may respond to bacterial infection with lymphocytosis rather than neutrophilia, and cer tain bacterial infections, particularly whooping cough and sometimes brucellosis, are characterized by lymphocytosis. In bacterial infection, the platelet count is often reduced but sometimes increased. Infection by Escherichia coli or shigella species can be followed by a microangio pathic haemolytic anaemia as part of a haemolytic uraemic syndrome. Coxiella burnetti, the coccobacillus that causes Q fever, can cause a haemolytic uraemic syndrome as well as a Bone Marrow Pathology, Fifth Edition. Sepsis due to Clostridium welchii can be complicated by acute haemolysis with spherocytic red cells. Mycoplasma infection is commonly asso ciated with the production of cold autoantibodies so that red cell agglutinates are present in blood films made at room temperature and haemolytic anaemia sometimes occurs. The presence of bacteria, either extracellu larly or within neutrophils, is usually only seen in overwhelming infections, particularly when there is associated hyposplenism. In relapsing fever, however, the characteristic spiral organisms of borrelia species appear episodically in the blood stream and are seen lying free between red cells. In ehrlichia and anaplasma infections, organisms are often detectable within monocytes or granu locytes. They are detected in monocytes in human monocytic ehrlichiosis (caused by Ehrlichia chaffeensis) and in neutrophils in human granulocytic anaplasmosis (caused by Anaplasma phagocytophilum, previously known both as Ehrlichia phagocytophila and E. The detection of organisms within leucocytes is facili tated by examination of buffy coat films. Anaemia is initially normocytic and normochromic but, as the infection becomes increasingly chronic, the anaemia develops the characteristics of the anaemia of chronic disease with the cells produced being hypochromic and microcytic. Pulmonary tuberculosis characteristically causes anaemia, increased rouleaux formation and, when severe, neutrophilia. Monocytosis occurs in a minor ity of patients, monocytopenia actually being more common. In miliary tuberculosis, leucocytosis and leucopenia both occur; similarly, both neutropenia and neutrophilia can occur [8]. Pancytopenia can occur but is uncommon [8]; sometimes it is a consequence of haemophagocytosis and, less often, it is associated with bone marrow necrosis. The anaemia in myco bacterial infection has the characteristics of anaemia of chronic disease. Rickettsial infections cause varied haemato logical effects, which may include neutrophilia, neutropenia, lymphocytosis, the presence of atypi cal lymphocytes and thrombocytopenia which is sometimes severe. Occasionally, severe infections are associated with a haematological picture that simulates leu kaemia, designated a leukaemoid reaction (see later in this chapter). Bone marrow cytology In severe bacterial infection, the bone marrow fea tures reflect those of the peripheral blood. In overwhelming infection, the marrow sometimes shows an increase of granulo cyte precursors but with few maturing cells. Macrophages are increased and, in a minority of patients with severe infection, prominent hae mophagocytosis occurs. Microscopy or bone marrow culture occasionally provides evidence of a specific infection. In human monocytic ehrlichiosis, organisms can be detected in bone marrow monocytes whereas in human granulo cytic ehrlichiosis they are present in granulocytes [13]. Bacteria vis ible within macrophages have also been reported in bacterial endocarditis. In typhoid fever, the bone marrow aspirate may show only nonspecific fea tures but bone marrow culture can be useful since it increases the detection rate by 50% in compari son with peripheral blood culture [15]; overall, stool cultures are positive in about 30% of patients, blood cultures in 60­80% and bone marrow cul tures in 80­95% [16]. In brucellosis, the bone marrow is usually hypercellular with prominent haemophagocytosis and increased eosinophils and plasma cells [17]. Occasional patients have pancy topenia associated with a hypocellular marrow [18]. Bone marrow culture is more often positive than blood culture, about 90% in comparison with about 70% [19], but, since the diagnosis can be made serologically, bone marrow aspiration is not indicated for this purpose. Chlamydophila pneumoniae has been detected in stromal cells and bone marrow monocytes/macrophages in two patients presenting with chronic anaemia [21]. Rarely in salmonellosis, large numbers of bacteria have been apparent in bone marrow films [22]. Megaloblastic anaemia, possibly related to folic acid deficiency, was found to be quite common in one study in leprosy [28]. However, the normal topographical arrangement of granulopoiesis is retained, with the more immature cells (mainly promyelocytes) found predominantly in the paratrabecular region [29]. Very rarely, there may be up to 50% plasma cells in the marrow in reactive conditions including infections. The differential diagnosis of increased numbers of plasma cells in the marrow is discussed on page 147. In infections, plasma cells are distrib uted through the marrow in an interstitial manner, often with focal pericapillary accentuation. This may be accompanied by plasma cell satellitosis, in which a central macrophage is surrounded by three or more plasma cells. The plasma cells have mature nuclear and cytoplasmic characteristics although there are often occasional binucleate forms and cells containing Russell bodies. Chronic infection is also associated with an increased frequency of reactive lymphoid aggregates (see page 145). Varying degrees of haemophagocytosis are common in infections by a wide variety of agents, including bacteria. Stromal changes related to infection include oedema, prominent sinusoids, focal reticulin fibrosis, red cell leakage into the inter stitial space and rarely, in very severe chronic infec tions, gelatinous change (see page 166). A decrease in marrow cellularity and loss of fat spaces usually accompany gelatinous transformation [33]. Anaplasma phagocytophilum has the capacity to infect granulocytic precursors and suppress bone marrow function [36]. Mycobacterial infections can cause the same reactive changes as infection by other bacteria. The bone marrow is usually hypercellular but a markedly hypocellular bone marrow can also occur [38]. In miliary tuber culosis, the majority of patients have granulomas and, in about half of them, caseation is present [8]. Herndier, San Francisco; reprinted by permission of the New England Journal of Medicine, 329, 1164, 1993. In one study, immunohistochemistry with a polyclonal antibody to mycobacteria was found to be more sensitive than an acidfast stain [39] but this has not found widespread use. Occasional patients with mycobacterial infection have extensive necro sis, which is indicative of poor prognosis. In those with impaired immunity, there may be a generalized increase in interstitial macrophages rather than granuloma formation.

Promote privacy in the clinic setting by following simple but often overlooked behaviors: · Do not discuss patient cases in the hallways. Shade visible computer monitors, ensure patients are offered a space to carry on private or sensitive conversations with staff at registration desks and vitals stations, and insulate exam room walls to prevent noise pollution. Balancing bedside manner with the need to efficiently and thoroughly document their treatment will be a growing challenge for physicians as technology continues to become an integral part of the health care experience. Electronic medical records come in as many varieties as patients-there are systems designed specifically for subspecialists or generic ambulatory models that can cross multiple specialties. However they are designed, their role in health care and clinic day-to-day operations is growing and critical. Medicare has begun tying reimbursement amounts to the use of this technology by providers through a program called Meaningful Use. The choice between paper and electronic medical charting is becoming obsolete, and drivers point towards a very near future where all medical doctors function on some degree of electronic medical records, often interconnected across practice lines. Medicare is introducing financial penalties, which follow closely behind a brief period of financial incentives, for providers based on their ability to demonstrate Meaningful Use. From the medical technologies and connectivity between them, to electronic visits and telemedicine, technologic advancement has set the stage for physicians to reach further distances to apply their skills. At the same time, technology has complicated the clinical setting by introducing a nonhuman element to patient care. Providers often document medical record information electronically throughout a patient encounter, which can Information technology is opening doors, not only for patient care and quality but also for management of physician practices as business entities. Regulatory and financial environments dictate constant change and require frequent reevaluation of practice viability. It is important to invest in a technology infrastructure that will allow decisions to be driven by data. There is a vast array of performance metrics, and within each metric there can also be multiple means of calculating the metric. Trending performance against both industry competitors and collaborators must be done with caution due to this variability. It is also highly recommended that trending be done against internal benchmarks, for example, reviewing the visit volumes of a practice in the current month compared to the same month prior year. This allows you to monitor both the health and viability of the practice as well as its likelihood to compete in a given market. Below is a list of some basic key performance indicators typical of a clinical practice dashboard. Chapter 201: Clinic Management 3339 Key Measures of Pradice Performance Metric Charges Importance to Clinic Management Total dollar value of services provided in a given time period. In managed care contracts, recall that the final reimbursement amount will be the contractual allowable, not the actual charge. Always charge equal to or greater than the contractual allowable to maximize collections. Charge amounts have a greater impact on self-pay patients, unless your practice has a discount policy. Most accurate measure of collections performance by calculating effectiveness of collecting total potential revenue. The primary source of income for most practices is fee-for-service patient care revenue; although some have other inputs such as contractual arrangements to provide consultative work or inpatient hospital coverage. Percentages are commonly broken down into the main five to six payer classes with the remainder defined as Other. Practices often measure Medicare, Medicaid, Insured, Uninsured, and break Insured down into the top three to four coverage plans. Knowing the percent of your patient population in each category will gauge whether reimbursement rates will suffice to cover overhead. How many patients are seen per exam room per hour, or how many of the allotted clinic hours are spent providing patient care gives some measure of productivity and also use of fixed overhead on space. The relative level oftime, skill, training, and intensity required to render a service. The committees assign a relative value after hearing testimony from specialty groups on how many hours or minutes it takes to perform a procedure, the level of skill required, the level of education/training required, and the practice expense associated with a procedure. Basic count of visits attended or bi lied by a physician can be a gauge of patient demand for services, supply or availability of the physician, or both. While demand continues to grow, in some markets supply of health care providers exceeds the community need. Marketing and attention to the public perception and understanding of your practice remain important survival tactics in the field. Any of the above incrementally or in combination will reach key audiences and promote growth. Above all, word of mouth prevails, and patients who have come to see you and had a stellar experience will be the most powerful marketing tool you have to grow your practice. Measuring quality improvement in healthca111: a guide to statistical process c;ontrvl applications. While not meant to be an exhaustive manual on how practitioners can become business savvy. Business acumen comes in time and with experience, but the highlights on clinic management include · Human resources-people are at the core of health care, and it is the most important investment of time and money you can make to develop a dependable, talented, aligned support staff. Among industrialized democracies, only the United States fails to provide universal health coverage. Among those with coverage, the number of people with employment-based insurance is falling. Due to recent job losses in the current economic downturn, another 2010 study by the independent Commonwealth Fund estimates that ·nine million working-age adults-57 percent ofpeople who had health inswance through a job that was lost-became uninsured in the last two years· (3). The study further notes that ·an estimated 44 million people were paying off medical debt in 2010, up from 37 million in 2005,· and that ·4 million declared bankruptcy because of medical bills. Although we do not cover evecyone in the United States, we spend far more per capita than other similar countries and yet have significantly worse outcomes. This compares to an estimated $5,350 in Norway, the next highest spender, and $4,363 in neighboring Canada (4). In effect, one could say that we pay enough in taxes to achieve universal coverage, but do not receive it. One approach looks at ·deaths from treatable conditions," termed ·amenable mortality. But more machines, and fewer doctors and hospital beds, do not equate to longer life expectancy nor lower infant mortality. My personal perspective, based on my reading of relevant research, is that such a system would provide the most rational and cost-effective solution to the problem of the uninsured. You will make your living as an otolaryngologist via compensation from our medical system (or fragmented parts of it, as detailed below), throughout your career. If your doors are open to them, self-pay patients-a euphemism for the uninsured-will likely present themselves in your clinic every week. We are also alone in having a predominantly for-profit health insurance industry, in which insurers are private corporations that (must) generate dividends for stockholders and multimillion-dollar incomes for top executives. A study of over 60,000 laryngeal cancer patients in the National Cancer Database from 1996 to 2003 found that "individuals lacking insurance or having Medicaid are at greatest risk for presenting with advanced laryngeal cancer" (10). They found that, "after controlling for other sociodemographic characteristics, patients with advanced oropharyngeal cancer at diagnosis were more likely to be uninsured (odds ratio 1. They noted that, after ·controlling for covariates [patient sex:, age, race, treatment facility type, zip code-based education and income categories, and U. Census region]," this association reached a very high statistical significance, with a value of P < 0. In a long-standing free annual community head and neck screening clinic conducted by the University of Michigan Department of Otolaryngology, "lack of insurance (P =0. The 10M, the health arm of our National Academies, has noted for a number of years that, "for adults without health insurance [emphasis in original], the evidence shows. The 10M physician representative who testified before Congress on its most recent report on the uninsured, Dr. John Ayanian of Harvard Medical School, noted in his testimony that "Uninsured adults are 25 percent more likely to die prematurely than insured adults overall, and with serious conditions such as heart disease, diabetes or cancer, their risk of premature death can be 40 to 50 percent higher" (14). Lack of insurance, of course, is not the only factor contributing to the delay of diagnosis and treatment in seriously ill patients, including head and neck cancer patients. There are what have been termed "patient delay" factors, including vague or nonurgent-appearing symptoms. There are also ·professional delay" factors, attributable to clinicians initially evaluating head and neck malignancies, in diagnosis and/or referral. These delays have been Chapter 202: Comparative Medical Systems 3343 identified for over two decades as a contributing factor in the advanced stage at which oral and oropharyngeal carcinomas are often diagnosed (15), for example. If a sodety considers medical care to be an economic commodity, then you set up a system that distributes health care based on the ability to pay. He also interviewed many physicians and policymakers, in many industrialized democracies. He detailed his experiences and conclusions in a television documentary and a best-selling book. Reid writes at length about his conversations with the Harvard economist William Hsiao, who has been involved in setting up health care systems in over a dozen countries. Hsiao (19) has coauthored a prominent textbook, Getting Health Reform Right, and his ·team of health system analysts was commissioned by the Vermont Legislature to develop and evaluate three options for health system reform and determine which option would best achieve the stated goals" (20). His team "found that the system capable of producing the greatest potential savings and achieving universal coverage was a single-payer system. If the people believe that medical care is a basic right, you design a system that means anybody who is sick can see a doctor. As Reid notes, ·all the developed countries except the United States have decided that every human has a basic right to health care. Taiwan, and others) · the Out-of-Pocket model While most wealthy democracies have adopted one of the first three models exclusively. Additionally, in a universal coverage approach with insurance, health insurance can be singlepayer, or multi-payer. The United States has a hodgepodge of different approaches, but its multi-payer (usually forprofit) insurance system does not provide universal coverage and access. Our Medicare program is single-payer national health insurance program for seniors. Medicare reimburses physicians in private (or academic) practice who care for these seniors. Medicare is a "third-party payer," separate from the patient (first party) and the provider (second party). Physicians compete against one another, in the marketplace, for these senior patients, although all physicians get paid by the same government insurance system. In ·cares for roughly one-fifth the population of the United States but spends only one-fifteenth of the U. And yet the results are good: Britain has lower child mortality, longer healthy life spans, and better recovery rates from most major diseases than does the United States· (21). Just as there are downsides to the lack of universal coverage in the United States, including avoidable deaths, the Beveridge model has downsides. Unlike American insurers, though, the sickness funds must accept anyone and pay any legitimate claims by providers. The wealthy can "opt out" and buy private coverage from for-profit companies, which about 7% of the population chooses to do (17). Reid also details his experiences in other Bismarck-type systems, in France and Japan. First of all, the insurance system does not have to generate profits, above and beyond providing care for enrollees. Because there is no reason to exclude sick patients, the system does not have to expend resources "cherry-picking" healthy individuals. Physicians and other providers do not have to employ staff to sort through different payers, claims processes, denials of coverage for appropriate services, and other similar administrative headaches. A study of the administrative costs of health care in the United States and Canada in fiscal 1999 found total administrative costs in the United States of $1,059 per capita, compared to $307 per capita in Canada. The authors note that ·canadian physicians send virtually all bills to a single insurer" (26). Though both Canada and Taiwan have a single-payer system, there is a notable "policy· difference between them. When Taiwan adopted a single-payer system in 1994, one of its authors, Harvard economist William Hsiao, made sure that employee and employer contributions to fund the system were termed a health insurance "premium, · rather than a "tax. A detailed history of the evolution of the Bismarck model in Germany is available from the European Observatory on Health Systems and Policies. If you are 65 or older (disabled or have end-stage renal disease), you are in a singlepayer government-financed insurance system, and you can see your choice of any participating, competing private provider, through Medicare. If you are poor enough (criteria vary by state), you may qualify for governmentfinanced Medicaid, though generally fewer private providers accept that third-party payer for their services, because of low reimbursement.
