A conflict of interest is a set of circumstances that creates a substantial risk that professional judgment or actions regarding a primary interest will be unduly influenced by a secondary interest side effects of antiviral drugs purchase mebendazole 100 mg on-line. Although the information in this report can be applicable to many types of conflict of interest hiv viral infection cycle mebendazole 100 mg for sale, it focuses on financial conflicts of interest hiv infection blood transfusions purchase mebendazole 100 mg fast delivery, which can occur when medical professionals interact with the pharmaceutical industry hiv infection duration buy 100mg mebendazole otc. For example hiv infection condom burst 100mg mebendazole free shipping, when physicians accept support for clinical research or continuing education programs antiviral homeopathic purchase mebendazole 100mg mastercard, accept consultantships and appointments to industry-sponsored speakers bureaus, or have informal meetings with pharmaceutical sales representatives who buy lunch and bring drug samples, there is concern about the impact of these relationships on prescribing behaviors and professional responsibilities (Marco et al. The purpose of this paper is to bring basic psychological research to bear on understanding financial conflicts of interest in medicine and effectively dealing with these conflicts. A particular focus will be research on self-serving biases in judgments of what is fair. This research shows that when individuals stand to gain by reaching a particular conclusion, they tend to unconsciously and unintentionally weigh evidence in a biased fashion that favors that conclusion. Application of this research to medical conflicts of interest suggests that physicians who strive to maintain objectivity and policy makers who seek to limit the negative effects of physician-industry interaction face a number of challenges. This research explains how even well-intentioned individuals can succumb to conflicts of interest and why the effects of conflicts of interest are so insidious and difficult to combat. The section Unconscious and Unintentional Bias describes the psychological research on bias in more detail, and its relevance to financial conflicts of interest will be made clearer. The section Parallel Evidence in the Medical Literature then provides a brief review that demonstrates the correspondence between the findings from studies of conflicts of interest in the medical field and the findings from basic studies of bias in the field of psychology. The section Implications for Policies Dealing with Medical Conflict of Interest details for policy makers how approaches including educational initiatives, mandatory disclosure, penalties, and limiting the size or type of gifts can be informed by the psychological bias literature. The Methods and Limitations of the Data briefly addresses the propriety of applying psychological experiments to professionalism in medicine. Finally, a conclusions section summarizes what can be learned from the psychological literature. Physicians have taken an oath to put their professional obligations first, so that if they are indeed influenced by private financial incentives, they have chosen not to uphold that oath. Although there may indeed be a minority of individuals who are fundamentally corrupt, most physicians certainly try to uphold ethical standards. This intuition is implicit in the guidelines set forth by the American Medical Association, the American College of Physicians, and the self-imposed guidelines of the Pharmaceutical Manufacturers Association, all of which stress that gifts accepted by physicians should primarily entail a benefit to patients and should not be of substantial value, suggesting that the temptation to provide or accept large or personal gifts is a concern. This view perhaps suggests that physician relationships with the pharmaceutical industry are problematic and can elicit hostility from some physicians. Understandably, most physicians see themselves as ethical people who would not place their objectivity for sale, and so they believe that they can be trusted to navigate these conflicts when dealing with industry. This prompts responses that physicians are "above sacrificing their self-esteem for penlights" (Hume, 1990) or that if panelists on a scientific committee are influenced by receiving reimbursement for travel and expenses, someone "bought their opinions" and "they obviously come cheap" (Coyne, 2005). This view is also compatible with an orthodox economic approach, which casts succumbing to conflicts of interest as the rational output of a cost-benefit calculation. In that case, solutions to problems of conflicts of interest would involve better monitoring and punishment, hopefully to the point at which ethical lapses would be too costly to indulge. Evidence from psychology offers us a different view, one in which our judgments may be distorted or biased in ways of which we are unaware. Some of the most compelling evidence of bias comes in the domain of optimism about the self. There is, for example, much evidence that people engage in self-deception that enhances their views of their own abilities (Gilovich, 1991). One of the most oft cited and humorous examples of selfenhancement is found in a study that reported that 90 percent of people thought they were better drivers than the average driver (Svenson, 1981). Such biases have been dubbed "self-serving" (Miller and Ross, 1975) when they lead one to take credit for good outcomes and blame bad outcomes on external sources. Although an unrealistic optimism about the self is sometimes adaptive and healthy (Taylor and Brown, 1988), these biases can lead to judgments that are unwise or unjust in situations in which we are epistemically responsible for being correct. Perhaps most relevant to the issue of financial conflicts of interest are well-known self-serving biases in the interpretation of what allocations are fair or just. A classic demonstration of self-serving bias in fairness comes from a study by van Avermaet (reported by Messick, 1985). When the subjects finished, the experimenter left them with money that they could use to pay themselves and send in an envelope as pay for another subject who had already left. In four different conditions, the subject was told one of the following four different conditions: (1) the other subject had put in half as much time and had completed half as many surveys, (2) the other subject had put in half as much time but had completed twice as many surveys, (3) the other subject had put in twice as much time but had completed half as many surveys, or (4) the other subject had put in twice as much time and had completed twice as many surveys. It is first interesting to note that almost everyone took the trouble to send the other person a share of the money, even though they were free to keep it all. It was not clear to the author that the rare cases of nonreturn were not due to a mistake or a lost envelope. How they shared the money, however, provides an interesting insight into human nature. The subjects who worked twice as long and completed twice as much kept twice as much money, on average, a simple application of a merit principle to pay. The subjects kept more than half of the money, however, both under the condition in which they worked longer and completed less and under the condition in which they completed more work and did not work as long. Again, their behavior was consistent with a merit principle, but the principle chosen, on average, systematically favored the subject making the allocation. Finally, when the subjects completed only half as much work and worked only half as long, they did not, on average, give the other subject twice as much money. Instead, the subjects kept about half of the money, on average, consistent with a rule of equal division rather than merit. What we can take away from the van Avermaet study is that most people are not unabashedly selfish; they have a sense of what is fair and tend to abide by it. Yet, that does not mean that judgments of fairness are not systematically biased to favor the self. When people are free to choose among competing principles of fair behavior, they tend to gravitate toward those principles that most favor their own interests. Other early experiments have similarly found that interpretations of fair allocations of pay are self-servingly biased (Messick and Sentis, 1979). One potential shortcoming of these experiments, however, is that they used a survey methodology. Thus, although it is apparent that the subjects had malleable interpretations of what was fair, it is not always clear whether these interpretations reflected a bias or, for example, a strategic effort on the part of the subjects. In that case, one wonders if the use of sufficient compensation would erase the effect. The subjects were randomly assigned to the role of either the plaintiff or the defendant and were asked to negotiate a settlement in the form of a payment from the defendant to the plaintiff. At the outset, the experimenters gave the defendants a monetary endowment to finance the settlement, and the division of the endowment that the subjects agreed upon through bargaining was what they took home as pay. Before they negotiated, both the plaintiffs and the defendants were asked to predict how the neutral judge would rule in the case and were also paid for the accuracy of this prediction. The subjects in this experiment had every incentive to be objective in seeking a settlement; if their demands were unreasonable, the pot of money would only shrink and ultimately the award would be determined by a neutral and informed party. This evidence suggests that self-serving biases are unintentional because people are often unable to avoid being biased, even when it is in their best interest to do so. In this way, any motivation to interpret evidence as favorable to one side over another while the subjects were reading and evaluating the materials was removed. The finding is important, however, because these subjects still had the same bargaining task as in the earlier experiments. Thus, one cannot conclude that the majority of failures to settle were due to the subjects being overly competitive or having a poor strategy. Rather, manipulations targeting the objectivity of the fair ruling judgment increased the settlement rates. This finding suggests that self-serving biases work by way of distorting the way that people seek out and weigh information when they perceive that they have a stake in the conclusion. The motivated reasoning displayed by the subjects in the study of Loewenstein et al. Gilovich (1991) describes the different evidential standards that people typically use to evaluate propositions that they wish to be true versus propositions that they wish to be false. These different evidential standards are exemplified by studies that use a variant of the classic Wason card selection task (Wason, 1966). The Wason task asks subjects to test an abstract logical rule by choosing which pieces of information that they want to be revealed to them. An overwhelming majority of subjects, even those with high levels of formal education, fail to reason through this task properly. The most common mistake that they make is selecting information that could confirm the rule but that is useless for testing it while failing to select information necessary for testing the rule because it could disconfirm it. Dawson and colleagues (2002) modified the Wason card selection task by having subjects sometimes test hypotheses that they did not want to believe, such as those that implied their own early death. This finding is interesting because it shows not only that people approach the problem differently when the hypothesis is agreeable or disagreeable but also that the proper motivations can lead them to solve problems that they are otherwise incapable of solving. For example, a physician may evaluate evidence that a particular treatment is effective. It did help the subjects recognize bias, but mostly in their negotiating opponents rather than in themselves. Moreover, those subjects who did concede that they might be somewhat biased tended to drastically underestimate how strong their bias was. This finding-that teaching people about bias makes them recognize it in others but not themselves-has since been confirmed and extended. That is, the average subject repeatedly sees himself or herself as less biased than average, a logical impossibility in the aggregate that suggests that self-evaluations of bias are systematically biased. Furthermore, experiments have shown that when people rate themselves as being less biased than they rate the average person, they subsequently tend to insist that their ratings are objective (Pronin et al. Why do people recognize less bias in themselves than in others, and why does education not make this bias go away? Because biases like the self-serving bias operate below the level of conscious awareness, they can "see" that they are not biased; at least, they have no experience of bias and so conclude that they are not biased. When they assess bias in others, however, people do not have the privilege of knowing what a person thought and must rely on inferences based on the situation. People will often still hold that they are not biased because they "know" their own thoughts, but they will now know what to look for in a situation that could bias others. The bias blind spot gives us one way of understanding why such strong disagreements can take place over whether conflicts of interest are problematic. In summary, psychological research suggests that people are prone to having optimistic biases about themselves. Judgments about what is fair or ethical are often biased in a self-serving fashion, leading even ethical people to behave poorly by objective standards. Self-serving bias is unconscious and unintentional, and people often fall prey to it even when they do not want to do so and they do not know they are doing it. The bias works by influencing the way in which information is sought and evaluated when the decision maker has a stake in the conclusion (financial or otherwise). Teaching about egocentric biases like the self-serving bias does little to mitigate them because when people examine their own thinking, they do not experience themselves as being biased. People do learn to look for bias in others, however, which can lead them to conclude that others are biased while they themselves are not. The findings in the medical literature, however, correspond nicely with the findings from basic psychological studies of bias. This correspondence serves as support for the idea that the model of unconscious and unintentional bias can help us understand conflicts of interest in medicine. Most prominently, although some physicians may admit to the possibility of being influenced, physicians typically deny that they are influenced by interactions with and gifts from industry, even though research suggests otherwise (Avorn et al. Accumulating evidence suggests that physicians believe that other physicians are more likely to be influenced by gifts than they themselves are (McKinney et al. Findings that residents in general believe that others are more likely to be influenced by interactions with industry than they are have been confirmed in a more recent review (Zipkin and Steinman, 2005). Even medical students see gifts of equal value as being more problematic for other professions than their own (Palmisano and Edelstein, 1980). Orlowski and Wateska (1992) tracked the pharmacy inventory usage reports for two drugs after the companies producing the drugs sponsored 20 physicians at their institution to attend continuing medical education seminars. However, before they attended the seminars, all but one of the physicians denied that the seminars would influence their behavior. Interestingly, these same physicians were often not even able to recall the sponsored grand rounds, so they were not consciously aware that it had any influence on their decisions. If conflicts of interest in medicine can indeed be understood as unconscious and unintentional, how might that affect how policy makers approach dealing with them? These interventions may be implicitly predicated on the view that succumbing to conflicts of interest is a conscious choice, however, and thus they may have limited or surprising effects if physicians are subject to unconscious bias. The psychological research reviewed here suggests that policy makers may wish to be cautious in their expectations of success for these policies, as they are not tailored to deal with unconscious bias. Policy makers may also wish to consider some possible perverse consequences that can result from using these interventions. Education Educational initiatives can be thought of as taking two forms: substantive education in ethics and education aimed specifically at describing and explaining institutional policies and enforcement and individual responsibilities. Perhaps the biggest barrier to the effectiveness of teaching about bias specifically is the bias blind spot. Certainly, some value exists in teaching physicians about potential conflicts of interest when they are dealing with industry. The blind spot suggests one reason why many physicians deny that they are personally influenced by gifts from industry, despite evidence that gifts and interactions do influence decision making.

We evaluate whether maternal receipt of influenza and Tdap vaccines increases the risk of infant hospitalization or death in the first 6 months of life antiviral infection 100mg mebendazole fast delivery.

Page 2 conditional logistic regression to estimate odds ratios for maternal exposure to influenza and/or Tdap vaccines in pregnancy. Of these, 25 222 infants had hospitalizations and 157 infants died in the first 6 months of life. We found no association between infant hospitalization and maternal influenza (adjusted odds ratio: 1. We found no association between infant mortality and maternal influenza (adjusted odds ratio: 0. These findings support the safety of current recommendations for influenza and Tdap vaccination during pregnancy. Both pertussis and influenza infections are associated with hospitalizations and fatalities in infants, and severity is highest before infants are eligible for the respective vaccines. Approximately half of infants <4 months of age with pertussis require hospitalization, and the majority of deaths from pertussis occur in these infants. In 2010, the leading causes of hospitalizations in infants 12 months were (1) acute bronchitis (238 per 10 000 population), (2) jaundice (104 per 10 000 population), and (3) pneumonia (56 per 10 000 population). We excluded pregnancies in which a live vaccine was administered because live vaccines are contraindicated in pregnancy. Furthermore, we excluded all infants who died during their delivery hospitalization because cause of death in these infants is often a perinatal complication (such as placental abruption) that would likely be unrelated to maternal vaccination. Page 4 Case-Control Matching Author Manuscript Author Manuscript Author Manuscript Author Manuscript Among infants meeting inclusion criteria, those infants with hospitalizations or deaths within the first 6 months of life were included in this analysis. For infants with >1 hospitalization, the first hospitalization was selected for each category (ie, first all-cause hospitalization, first respiratory hospitalization). Furthermore, an infant could be included as a death case patient and hospitalization case patient if the infant was hospitalized and later died. Because of lag time in the death data, we evaluated deaths occurring from January 1, 2004, to December 31, 2013, and hospitalizations from January 1, 2004, to December 31, 2014. Matched controls for the infant mortality analysis were selected among infants in the study who survived the first 6 months of life. Matched controls for the infant hospitalization and respiratory hospitalization analyses were selected from infants without death or hospitalization in the first 6 months of life. With our optimal matching, we successfully found controls for 100% of our case patients by using these parameters. Vaccinations the exposure of interest was maternal vaccination with any influenza and/or Tdap vaccines during pregnancy. A vaccine during pregnancy was defined as one given from 7 days after the pregnancy start date to 7 days before the pregnancy end date. These time windows were chosen to avoid including exposures to vaccinations given before or immediately after pregnancy. We stratified vaccine exposures as any influenza vaccine (with or without Tdap), any Tdap vaccine (with or without influenza), and both influenza and Tdap vaccines in the same pregnancy. In our evaluation of maternal influenza vaccine, we also repeated our analysis limiting outcomes to events occurring during the influenza season (October through May), to ascertain any protective findings that may be more evident when influenza virus is circulating. We also did a sensitivity analysis stratifying our exposure by influenza vaccine only and Tdap vaccine only to see if our results would differ by limiting our exposure groups. Statistical Analysis We measured rates of influenza and Tdap maternal vaccination in our study cohort from 2004 to 2013. We also measured trends of infant deaths and hospitalizations during this same time period to look for any ecological associations between maternal vaccination and our infant outcomes. Page 5 analysis to estimate the odds of maternal vaccination in matched case patients and controls. We reviewed clinical information relating to a potential influenza- or pertussis-related cause of death and laboratory data in the 2-week period preceding death. Of the remaining 413 034 infants, 25 222 infants had 1 or more hospitalizations and 157 infants died. Of the deaths, 14 (9%) had a respiratory cause of death; however, none of these deaths were considered to have been caused by influenza or pertussis infections on the basis of our laboratory and medical record review. Of the 157 infants that died, the age at death ranged from 1 to 180 days with a mean of 61 days and a median of 51 days. The most common causes of death were unknown causes (32%), sudden infant death syndrome (21%), and certain conditions originating in the perinatal period (17%). We analyzed overall trends of influenza and/or pertussis vaccination in pregnancy and trends of infant hospitalization and mortality in our study population from 2004 to 2013 (Fig 2). From 2004, there was an increase in maternal influenza vaccination, which became more dramatic in 2009 after the H1N1 influenza pandemic. Maternal Tdap vaccination increased starting in 2010 when California recommended pregnant women to receive Tdap in Pediatrics. We matched case patients with eligible controls and compared characteristics between these groups (Table 1, Supplemental Table 3). Infants who were hospitalized were more likely to have mothers with pregnancy complications, less likely to be delivered by cesarean delivery, and less likely to be of African American non-Hispanic or American Indian race. Mean maternal age, gestational age at delivery, and length of birth hospitalization were statistically significantly different between the groups but not clinically different. In our adjusted analysis, we found no significant association between infant hospitalization or death in the first 6 months of life and receipt of maternal influenza and/ or Tdap vaccines and no significant association between infant hospitalization from respiratory causes and maternal influenza vaccine (Table 2). However, the odds of maternal Tdap vaccination was significantly lower among infants with hospitalizations because of respiratory causes (adjusted odds ratio: 0. Furthermore, when evaluating infant hospitalizations and death occurring during periods of influenza virus circulation (October through May) and peak influenza virus circulation (November through February), we found no association with maternal influenza vaccine exposure (data not shown). When limiting our exposure groups to women receiving influenza vaccine without Tdap vaccine and Tdap vaccine without influenza vaccine, our results were similar to our main analysis (Supplemental Table 4). Our study helps strengthen the growing evidence of long-term safety of vaccination in pregnancy for infants. Our findings are similar to other studies that have evaluated infant mortality and morbidity after maternal vaccination in pregnancy, most of which have evaluated the safety of adjuvanted H1N1 influenza-containing vaccines. Unlike these previous studies, however, our study included women who received any type of influenza vaccine, none of which contain adjuvants in the United States, and we found similar results. Our findings are also consistent with studies in which researchers have evaluated infant mortality and morbidity after Tdap vaccination in pregnancy. Our study included a longer follow-up period than these previous studies and still showed no increased risk of infant mortality or hospitalization after maternal Tdap vaccination. Other long-term outcomes that have previously been studied after maternal Tdap vaccination include childhood development scores at 13 months of life,13 infant growth up to 5 to 7 months of age,24 and complex chronic conditions at 12 months of age. Our study managed a larger number of infants and had similar findings to these studies, further demonstrating long-term safety in infants of Tdap vaccine exposure in pregnancy. We did find a protective association between maternal Tdap during pregnancy and infant respiratory hospitalizations, which is consistent with results of other published studies that have looked at infant pertussis as an outcome. This could indicate that infants with pertussis are not being appropriately diagnosed and tested. We did this to ensure we had access to health care utilization data to avoid misclassifying case patients as controls. We looked at broad safety outcomes (hospitalizations, respiratory hospitalizations, and deaths) and may not capture true increases in a specific outcome, if such an association was present. We did not evaluate the risks of infant hospitalizations and mortality in multiple gestation infants, very preterm infants, and those with major birth defects because these infants are at a much higher risk of the outcomes we studied; therefore, our results are not generalizable to these Pediatrics. Author Manuscript Author Manuscript Author Manuscript Author Manuscript Sukumaran et al. Finally, we were sufficiently powered for our outcomes of hospitalizations and hospitalizations from respiratory causes but underpowered for the outcome of death. This is the first study in which infant hospitalizations and mortality in the first 6 months of life after maternal influenza vaccine and Tdap vaccines are evaluated. In this large casecontrol study, we found no increased risk of infant hospitalization and death after vaccination in pregnancy. Our findings support the safety of influenza and pertussis vaccinations during pregnancy for infants of vaccinated mothers.

Provider Incentive Programs: An Opportunity for Medicaid to Improve Quality at the Point of Care Resource Paper By: Dianne Hasselman Center for Health Care Strategies, Inc. March 2009 Provider Incentive Programs: An Opportunity for Medicaid to Improve Quality at the Point of Care Contents Introduction. Imagine a primary care physician whose performance in diabetes care is assessed through incentive programs from multiple health plans. Although the purpose of pay-for-performance (P4P) programs is to use financial incentives to "move the quality needle" in a deliberate manner and to increase value-based purchasing, the proliferation of incentive programs - particularly at the individual physician or practice level - is creating a patchwork of quality efforts with negative and unintended consequences. Many providers, frustrated with the numerous and fragmented performance reports they receive, discount or simply discard the data as confusing, inefficient, inaccurate, and unhelpful.

A* Usual Interstitial Pneumonia B C D Lymphocytic Interstitial Pneumonia Nonspecific Interstitial Pneumonia Respiratory Bronchiolitis Interstitial Lung Disease Rationale: A. Most common pattern of interstitial lung disease seen in patients with rheumatoid arthritis is usual interstitial pneumonia which portends a poor prognosis. Common pattern of interstitial lung disease encountered in many forms of collagen vascular disease such as scleroderma but not in rheumatoid arthritis. Most common presentation is upper-zone predominant vague centrilobular ground-glass nodules in smokers. Resultant post-obstructive atelectasis or mucus impaction can mask the underlying lesion. Typically manifests as diffuse tracheal wall thickening when the airway is involved, not a focal endobronchial nodule. Typically manifests as tubular fluid-attenuation opacities within the lung parenchyma with distal hyperinflation. Reference: Bronchial Carcinoid Tumors of the Thorax: Spectrum of Radiologic Findings.

A B C* D Rationale: Metastatic lung cancer Hodgkin lymphoma Mycobacterium tuberculosis Cystic hydatid disease (Echinococcosis) A. Additionally, pulmonary metastases most often manifest as bilateral, multi-focal, well-defined nodules or masses with a more spherical morphology and are most numerous in the lower lobes. Cavitation may occur and is most frequently associated with squamous cell carcinomas, but also described in adenocarcinomas and sarcomas. Intrathoracic involvement is seen in 75% of patients diagnosed with Hodgkin lymphoma. The most common radiologic manifestation is anterior mediastinal enlargement with "filling" of the retrosternal space on lateral chest radiography and a lobular mass growing to both sides of the midline with mass effect on frontal chest radiography. Cavitation is traditionally considered a manifestation of the post-primary pattern of tuberculosis. Other features of post-primary tuberculosis include multi-focal ill-defined 5-10mm air space nodular opacities, and pleural disease. Sputum analysis revealed 4+ acid-fast bacilli (more than 90) per high power field consistent with active tuberculosis. Pulmonary cystic hydatid disease (Echinococcosis) most often manifests as a well-defined spherical nodule or mass; variable in size, ranging up to 20 cm in diameter. This is when you can create opposing answers to the same problem depending on how the problem is posed. This represents overestimation or confidence in an answer or diagnosis, which can occur when the answer is already known. This is when physicians collect or present conclusions in ways to confirm rather than refute their hypothesis. When is a provider permitted to access the electronic medical record of a patient who was seen by another provider in the organization? A B Only when a new record for the patient is created based on personal patient interactions After new written consent is obtained from the patient C* When the provider is treating that patient or assisting another provider D Any time the provider has access to information available in the patient database 3. A B C D* Required for private insurance submissions Used for Medicare reimbursement only Not eligible for reimbursement Track use and acceptance of newer procedures and diagnoses 4. Having a basic understanding of the submission and billing process is the responsibility of the physician of record. Understanding the parties responsible for the codes affecting reimbursement is key to empower radiologist to play an active and supportive role in this critical issue. It is the obligation of these physicians to understand the basic use of modifiers and issues which could lead to advertent or inadvertent fraud. Modifiers, by definition, cannot alter the definition of the code to which it applies. A B C D* An average single amount predetermined by the exam protocol A multiple of a charge determined by Medicare Only for the quantity of pharmaceutical utilized the entire amount within the pharmaceutical container Rationale: A. A, B & C are each incorrect given that an institution can charge for waste pharmaceuticals if the material is not useable subsequently and the waste is documented. Contrast media utilized in various radiology exams and appropriate understanding is needed to avoid inadvertent fraudulent billing but as well appropriate utilization of materials/resources. A waiver of the requirement for documentation of informed consent may be granted under what circumstances? The requirement to document informed consent can be waived if the study poses no more than minimal risk to subjects and involves no procedures for which written consent is normally required outside of the research context. The requirement may also be waived if the only record linking the subject and the research is the consent document and the principal risk is a breach of confidentiality. If a researcher anticipates that subjects might be embarrassed by questions, this concern should be addressed in the consent process. A* B C D Accountable care organization Fee for service Managed care organization Health maintenance organization Rationale: A. In general, they focus on groups of healthcare providers in which the whole system receives a set amount of money for disease treatment (global capitation). These groups are accountable (across the board) for metrics/outcomes related to the patients they treat. Fee for service models are, in simple terms, basically getting paid a certain amount of money for performing a service. This has been an archetype in American healthcare but may not be so common in the future. Since capitation is not automatically associated with fee for service, answer B is incorrect.

Candida esophagitis is the most common cause of infectious esophagitis, and is typically seen in immunocompromised patients. Herpes esophagitis is the second most common cause of infectious esophagitis, and is also seen in immunocompromised patients. This typically has a granular or nodular appearance on barium esophagram, but can also manifest as small ulcers or erosions. A* B C D Hepatocellular carcinoma Lymphoma Angiosarcoma Intrahepatic cholangiocarcinoma Rationale: A. Angiosarcoma is rare, and has been associated with exposure to Thorotrast and vinyl chloride. A* Pancreatic adenocarcinoma B C D Autoimmune pancreatitis Intraductal papillary mucinous neoplasm Serous cystadenoma Rationale: A. Derived from ductal epithelium, pancreatic adenocarcinoma accounts for about 90% of all pancreatic neoplasms. Although more common in the pancreatic head and body, approximately 10% occur in the tail. Pancreatic adenocarcinoma tends to be scirrhous, without significant hemorrhage or necrosis. Liquefactive necrosis, cystic degeneration and dystrophic calcification are not usual features of this tumor. The tumor subsequently underwent locoregional spread with direct splenic invasion via the splenic hilum. Although autoimmune pancreatitis can cause sausage-like enlargement of the pancreas, it is usually diffuse and does not involve solely the tail as seen here. Enhancing stellate septae associated with a central scar which can have coarse calcifications have been reported in cases of serous cystadenoma. Hemangiomas typically demonstrate early peripheral enhancement with delayed fill-in. Infarcts typically appear as wedge-shaped areas of hypoenhancement in the spleen, as show in this case. Lymphoma is the most common malignancy that involves the spleen, and may present in various manners, including splenomegaly, a single large lesion, or multiple small lesions. What associated condition or finding would suggest the need for investigation for the presence of a lead point? A History of sprue B* Dilatation proximal to the intussusception C D Presence of ascites Adjacent 5-10 mm mesenteric nodes Rationale: A. There is an increased incidence of transient, non-obstructing small bowel intussusceptions in patients with sprue (celiac disease). Proximal small bowel dilation is concerning for an obstructing intussusception and should prompt evaluation for an underlying mass. Ascites is seen in a multitude of abdominal diseases and has no direct association with an obstructing intussusception. The most common predisposing condition for development of a splenic abscess is an immunocompromised state. Hemoglobinopathies may also uncommonly predispose the patient to developing a splenic abscess. Lee M-C, Lee C-M (2018) Splenic Abscess: An Uncommon Entity with Potentially Life-Threatening Evolution. Splenic Abscess in Immunocompetent Patients Managed Primarily without Splenectomy: A Series of 7 Cases. A patient with a history of celiac disease presents with recurrent abdominal pain and weight loss. A Cavitating mesenteric lymph node syndrome B* Lymphoma C D Whipple disease Mesenteric adenitis Rationale: A. This rare complication of celiac disease is characterized by cavitating/centrally necrotic lymph nodes not homogeneously enhancing nodes. Patients with celiac disease are at increased risk of lymphoma and this diagnosis needs to be excluded in patients that develop recurrent pain and/or adenopathy. There is no association between celiac disease and Whipple disease - a rare disease characterized by low density lymph nodes (when adenopathy is present). This is essentially a diagnosis of exclusion and the enlarged lymph nodes tend to be localized to the right lower quadrant - not the more generalized adenopathy described in the question. This could be considered if the lesion was >3cm, had concerning imaging/clinical features (ie. Iron within hepatocytes and increased total body iron in hemochromatosis are associated with an increased risk of cirrhosis and hepatocellular carcinoma [3]. Increased iron deposition has also been associated with other systemic disorders, including chronic viral hepatitis, alcoholic liver disease, and nonalcoholic steatohepatitis. You are shown images (Figures 6A and 6B) from a retrograde cystogram on a 48-year-old man who presented after a motor vehicle accident. A B C Extraperitoneal bladder rupture Traumatic colovesical fistula Ureteral transection D* Intraperitoneal bladder rupture Rationale: A. The contrast appears to be in the peritoneum, around bowel loops, not communicating with the lumen of a bowel loop. There is no evidence of ureteral filling or extravasation from a ureter to suggest ureteral transection. The images demonstrate intraperitoneal extension of contrast, compatible with intraperitoneal bladder rupture.

For each class hiv infection new york cheap mebendazole 100 mg overnight delivery, we provide for both the single-transmitter case and the multipletransmitter case hiv infection in new zealand 100 mg mebendazole sale. Under the new rules anti viral apps discount 100mg mebendazole with mastercard, every applicant for equipment authorization and every licensee prior to deployment or commencement of operations seeking to be exempt will use the calculations in our rules to determine whether the device or transmitter falls under one of the three classes of exemptions hiv infection dental work cheap mebendazole 100mg on line. These stations operate on towers that are separated from the public by a distance greater than required for evaluation hiv infection levels 100 mg mebendazole free shipping. For those relatively few instances where an evaluation may be required under the new rules hiv infection risk percentage purchase mebendazole 100 mg line, we expect this will be fairly straightforward. The calculations require only information that the applicants already have on hand, notably the operating frequency and effective radiated power. For the most part, these calculations will result in conclusions that are similar to our old rules. Further, to ease the transition to the new rules, we establish a transition period below to allow licensees and manufacturers an opportunity to determine whether they meet the criteria for an exemption. This includes, for example, simple answers to questions, guidance on how to file for authorization of new types of devices, and guidance on how to conduct compliance testing. The Commission also proposed using the term "exemption" (as opposed to "exclusion") for this topic and proposed a set of technical definitions related to output power and separation distance. No commenting party opposed the terminology or the definitions and we adopt them as shown in the Final Rules. Fixed services are now often used for backhaul for wireless communications and can be located on publicly accessible rooftops and structures near ground level that are not necessarily spatially removed from publicly accessible areas at similar height. We reiterate that the affirmative determinations only involve a simple analysis to determine whether an exemption is applicable. We also recognize that many licensees do not control all of the sites at which their antennas are located. Such leasing arrangements are contractual, and licensees can provide for owner attention to this obligation, including responsibility for any losses due to their failure to maintain compliance, as specific provisions of the lease. The rule presumes that all transmitters on ships operating under Part 80 are not exempt regardless of how they are installed and, by a lack of inclusion in the table, simultaneously presumes that all non-ship transmitters are exempt. On the other hand, services not listed in the Table are not required to be evaluated. For example, Table 1 indicates that building-mounted antennas with effective radiated powers as high as 2,000 watts are not required to be evaluated, depending on the applicable service rules, regardless of how far a distance these transmitters are separated from areas where persons can access. Although the rules do not require Part 15 devices, except those operating under the provisions of Sections 15. We further clarify that equipment authorized prior to the effective date of this Order may continue to be marketed and used under their existing authorizations. Parties deploying such equipment need only ensure that the equipment is installed consistently with the information in the installation manual or user instructions, as provided in the equipment approval, and no further analysis is necessary. Separation distance can be ascertained when installers visit the transmitter site to install equipment prior to operation. We observe that separation distance is well-defined in relation to the radiating structure (i. The new rules do not require any additional evaluation beyond what they should already undertake. The factors and calculations used to determine whether a transmitter is exempt can be reused to provide a generic template for ready exemption from evaluation of numerous sites. Facilities with lower power, greater directivity, or greater height are obviously already effectively evaluated without site-by-site application of the formula. Letter from Cheng-yi Liu, Counsel, Fixed Wireless Communications Coalition, to Marlene H. The new rules will replace these services with the streamlined exemption criteria and remove the specific references in the rules. These exemptions are based on calculations and measurement data indicating that such devices under conditions of normal use are unlikely to cause exposures exceeding the guidelines. It should be emphasized, however, that these are not exemptions from compliance, but, rather, only exemptions from routine evaluation. Eliminating service-based exemptions and replacing them with exemptions that are applied uniformly, regardless of the service being offered, simplifies the compliance framework. By adopting a service-agnostic approach to exemptions, our rules will no longer unduly burden developers who are making new uses of wireless technology. These specific exemption criteria are a generally-applicable set of formulas, based on power, distance, and frequency, for all services using fixed, mobile, and portable transmitters. Various simplifying conservative assumptions can be made; for example, if the height of an antenna above unpopulated space is known and is greater than required by the applicable exemption criterion, there is no need to measure lateral distance and calculate the hypotenuse, as that distance will always be greater than the (known) vertical distance. This guidance has been available for years and is an acceptable method to determine compliance. See Environmental Protection Agency, Near-Field Radiation Properties of Simple Linear Antennas with Applications to Radiofrequency Hazards and Broadcasting, Tell, Richard A. Moreover, our new rules do not prohibit the authorization of medical implants operating with power exceeding 1-mW; only that such devices would require routine evaluation for certification, which until now had been the case for all implant devices that contain wireless communications capabilities. Modification and Clarification of Policies and Procedures Governing Siting and Maintenance of Amateur Radio Antennas and Support Structures, and Amendment of Section 97. See Motorola Comments at 4( "As the Commission notes, under current rules, any transmitter with power of 1. If there is unauthorized modification, the device will be operating outside its grant of authorization and subject to enforcement action. Thus, a blanket exemption from routine environmental evaluation for these transmitters is appropriate. We have set the parameters of this formula to cover a wide range of use cases, while not unnecessarily complicating the calculations, allowing parties to readily determine if a device qualifies for the exemption. Other commenters suggested alternatives to our proposed approach, but we decline to adopt them. Moreover, some power measurement procedures may be specific to the particular wireless technology under consideration. These criteria, shown in Table 2 below, apply at separation distances from any part of the radiating structure of at least /2. When the maximum time-averaged effective radiated power is no more than the value calculated from the formulas, the source is exempt from further evaluation. For the exemption in Table 2 to apply, the separation distance in meters, R,146 must be at least /2, where is the free-space operating wavelength. Verizon is the only commenter to attempt to substantiate its argument - in its Technical Appx. In the typical case of a structure as suggested by Verizon, the appropriate placement of the antenna can provide the basis for an exemption and can be readily replicated for other structures. We acknowledge that in some cases the simplicity of the exemption provisions may require an evaluation that would not be required if the formula was more complex. We conclude, however, that we have struck the right balance between simplicity, accuracy, and ensuring safety, as well as between requiring more complex analysis in all cases and requiring it in only a small percentage of cases. We adopt a modified version of our 2013 proposals describing the appropriate summation formulas and the circumstances in which they apply. It is not apparent that realistically higher power and/or gain would not cause exposure over the limit. However, if the sum of multiple sources that can operate at the same time is less than 1 mW during the time-averaging period, they may be treated as a single source (separation is not required), and exempted accordingly. In addition, if pre-existing exposure levels are known, they may also be normalized to the exposure limits to determine the remaining margin for exemption of additional sources to demonstrate compliance with the limit. These concepts are applied to the antennas of multiple transmitters in a single device and to multiple fixed (Continued from previous page) 159 For example, if calculation determines that for a particular transmitter power and antenna type, the closest location at which the exposure limit is exceeded is X, installation elements that assure the antenna distance exceeds X can be repeatedly used without further assessment of each site. For example, in the case of an individual standing between a vertical reflector. Verizon fails to account for such vertical reflectors and resulting spatially-averaged field enhancements, which are particularly relevant at urban wireless facilities as powers increase and antennas continue to be installed on and adjacent to buildings. See Motorola Comments at 4; Medtronic Comments at 3; Wi-Fi Alliance Comments at 3; Wi-Fi Alliance Reply at 11. Typical devices today contain several transmitters and radiating antennas, some of which can operate at the same time. This formula includes three summation terms, the first two of which are summations for the exemptions, the third is to account for exposure from existing evaluations, which we will describe in more detail below. For example, if the source power is 30 W and the exemption threshold is 40 W, the normalized power would be 0. If the ratios for all transmitters in a device operating in the same timeaveraging period are included in the total sum and this sum is no more than one (i. If a transmitter is subsequently proposed to be added under our permissive change authorization procedures for portable or mobile devices, a new calculation must be made including the additional transmitter. However, because our exemptions do not rely on delivered power but available power, we decline to adopt a definition for "delivered maximum timeaveraged power," but we clarify here that the definition would be the largest net power delivered or supplied to an antenna, as averaged over a time period not to exceed 30 minutes for fixed sources, or as averaged over a time period inherent from the device transmission characteristics for mobile and portable sources (also not to exceed 30 minutes). Medtronic also suggests that short time-averaging periods for non-overlapping transmission should be included in the rules. This summation formula may be used even if some of the three terms do not apply (i. There were relatively few other comments directly addressing the proposed summation formula for the exemption of multiple fixed transmitters. While it did not object to the formula, Verizon considered each of the methods/summation terms as representing an independent method to determine exemption and suggested that different methods could be used for different sources, as appropriate, in determining the contribution of individual transmitters at a multiple transmitter site. C, Transmitter-Based and Device-Based Time-Averaging (we seek comment on how applications of these exemption criteria and accounting for overlapping transmissions and time-averaging periods might be either similar or different in the context of transmitter/device-based time-averaging). We find that there is no reason or circumstance for which a transmitter should be counted more than once in the overall sum for any particular exposure location. This should be most useful when a fixed transmitter is being added to a dense antenna facility. Where existing exposures collectively are not significant,181 the Evaluated third term in the summation may be disregarded. The P and Evaluated terms may be most commonly used in situations where, for example, multiple transmitter modules are installed in a small device. As far as the discussion by commenters of various summation methods, the method we adopt is simple, consistent, and conservative. We conclude that for these reasons, the summation of potential exposure due to spatially uncorrelated sources should not be routinely required and our conclusion is consistent with all known compliance activities to date. In other cases, the evaluation may be more complex, requiring more precision with regard to transmitter power and antenna distance from a space that persons can access. Lai (Levitt/Lai) Comments at 14; Hubert Comments at 3 (expressing concern about the cumulative effect of exposure from many sources even where the total exposure is far below our exposure limits). Therefore, actual measurements often result in lower exposure values due to these conservative assumptions often employed in computational methods, but using maximum power and other conservative assumptions can provide a simpler, less burdensome means of demonstrating compliance and will continue to be permitted where they can be successfully supported. Fully validated means that a method has been tested and shown to provide results equivalent to those derived from already accepted methods for the same canonical device(s). Applicants must provide specific justification for measurement distances used in compliance testing, describing the normal and feasible usage(s) of the device, and certification review will specifically include evaluation of the propriety of this specification, including any measures that may be taken to ensure that it is maintained. The public is invited to make comments and provide suggestions to the documents made available at this page. At the end of the comment period, revised documents may be published, withdrawn or modified and submitted for additional review. The Commission has not received any complaint regarding any of the guidance provided and or the process itself. Further, we also modified our rules for measurement procedures to make it clear that "any measurement procedures acceptable to the Commission may be used to prepare data demonstrating compliance with the requirements of this chapter. With the proliferation of wireless base stations that are increasingly smaller in size, sometimes concealed or camouflaged, and often located close to where persons pass, linger, or work, additional measures are needed to ensure that exposure in excess of our general population limits is permitted only for those with proper training and capability to limit their exposure. Such post-evaluation mitigation measures include labels, signs, markings, barriers, positive access controls, and occupational training. These measures range from precluding members of the general public from entering areas where exposure exceeds the general population continuous limit (general population / uncontrolled), to measures allowing only trained workers to enter an area that exceeds the continuous occupational limit either briefly, with protective clothing, or with an exposure monitor so that compliance with the occupational limit with 6-minute time averaging is maintained (occupational/controlled) environments. This pertains primarily to fixed sites; mitigation measures for mobile and portable devices are typically based on device features such as proximity sensors or device-controlled time averaging. Positive access control includes locked doors, ladder cages, or effective fences, as well as enforced prohibition of public access to external surfaces of buildings, or generally, affirmative physical measures for preclusion of unauthorized access. It does not include natural barriers, which might limit access effectively in some, but not all cases, or other access restrictions that did not require any action on the part of the licensee or property management. Currently, our rules provide that occupational exposure limits could apply to untrained persons, provided that the exposure is "transient" and they are informed of the exposure potential and the appropriate means to mitigate their exposure. We adopt our proposed definition of transient exposure as the brief exposure in a controlled environment that does not exceed the general population limit, which may be averaged over a time interval up to 30 minutes. Our rules do not specify how much above that general population limit an instantaneous exposure is permitted to be. The continuous exposure limits are generally used to define the boundaries of controlled areas where "behavior-based" time averaging may be necessary. We generally refer to simply the "exposure limit," when "behavior-based" time averaging is not considered. There are only two sets of limits-those which apply to supervised/trained workers (in an occupational setting) and those which apply to the general population (which includes unsupervised and untrained workers). The rules we adopt today will require, for controlled areas where the general population limit is exceeded, access controls and appropriate signage in addition to supervision of transient individuals by trained occupational personnel. The supervision requirement is reasonable because it ensures that within a controlled area exposure above the general public limits is only transient. Furthermore, these workers may have the opportunity to make personal decisions in regard to their exposure, based on the relative risk as they perceive it. We find no basis for permitting exposure of any untrained individuals-regardless of whether they are workers-greater than the general population exposure limit. The applicability of occupational limits requires that a person is fully aware and able to exercise control over his or her workrelated exposure.
