Abstract
Pneumocystis jirovecii can cause life-threatening pneumonia in immunocompromised patients. Traditional diagnostic testing has relied on staining and direct visualization of the life-forms in bronchoalveolar lavage fluid. This method has proven insensitive, and invasive procedures may be needed to obtain adequate samples. Molecular methods of detection such as polymerase chain reaction (PCR), loop-mediated isothermal amplification (LAMP), and antibody-antigen assays have been developed in an effort to solve these problems. These techniques are very sensitive and have the potential to detect Pneumocystis life-forms in noninvasive samples such as sputum, oral washes, nasopharyngeal aspirates, and serum. This review evaluates 100 studies that compare use of various diagnostic tests for Pneumocystis jirovecii pneumonia (PCP) in patient samples. Novel diagnostic methods have been widely used in the research setting but have faced barriers to clinical implementation including: interpretation of low fungal burdens, standardization of techniques, integration into resource-poor settings, poor understanding of the impact of host factors, geographic variations in the organism, heterogeneity of studies, and limited clinician recognition of PCP. Addressing these barriers will require identification of phenotypes that progress to PCP and diagnostic cut-offs for colonization, generation of life-form specific markers, comparison of commercial PCR assays, investigation of cost-effective point of care options, evaluation of host factors such as HIV status that may impact diagnosis, and identification of markers of genetic diversity that may be useful in diagnostic panels. Performing high-quality studies and educating physicians will be crucial to improve the rates of diagnosis of PCP and ultimately to improve patient outcomes.

Abstract
The aim of this study was to investigate association between HIV and family planning integration and technical quality of care. The study focused on technical quality of client-provider consultation sessions. The cross-sectional study observed 366 client-provider consultation sessions and interviewed 37 health care providers in 12 public health facilities in Kenya. Multilevel random intercept and linear regression models were fitted to the matched data to investigate relationships between service integration and technical quality of care as well as associations between facility-level structural and provider factors and technical quality of care. A sensitivity analysis was performed to test for hidden bias. After adjusting for facility-level structural factors, HIV/family planning integration was found to have significant positive effect on technical quality of the consultation session, with average treatment effect 0.44 (95% CI: 0.63-0.82). Three of the 12 structural factors were significantly positively associated with technical quality of consultation session including: availability of family planning commodities (9.64; 95% CI: 5.07-14.21), adequate infrastructure (5.29; 95% CI: 2.89-7.69) and reagents (1.48; 95% CI: 1.02-1.93). Three of the nine provider factors were significantly positively associated with technical quality of consultation session: appropriate provider clinical knowledge (3.14; 95% CI: 1.92-4.36), job satisfaction (2.02; 95% CI: 1.21-2.83) and supervision (1.01; 95% CI: 0.35-1.68), while workload (-0.88; 95% CI: -1.75 to - 0.01) was negatively associated. Technical quality of the client-provider consultation session was also determined by duration of the consultation and type of clinic visit and appeared to depend on whether the clinic visit occurred early or later in the week. Integration of HIV care into family planning services can improve the technical quality of client-provider consultation sessions as measured by both health facility structural and provider factors.

Abstract
The incidence and prevalence of fungal infections in Tanzania remains unknown. We assessed the annual burden in the general population and among populations at risk. Data were extracted from 2012 reports of the Tanzanian AIDS program, WHO, reports, Tanzanian census, and from a comprehensive PubMed search. We used modelling and HIV data to estimate the burdens of Pneumocystis jirovecii pneumonia (PCP), cryptococcal meningitis (CM) and candidiasis. Asthma, chronic obstructive pulmonary disease and tuberculosis data were used to estimate the burden of allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA). Burdens of candidaemia and Candida peritonitis were derived from critical care and/or cancer patients' data. In 2012, Tanzania's population was 43.6 million (mainland) with 1,500,000 people reported to be HIV-infected. Estimated burden of fungal infections was: 4412 CM, 9600 PCP, 81,051 and 88,509 oral and oesophageal candidiasis cases respectively. There were 10,437 estimated post-tuberculosis CPA cases, whereas candidaemia and Candida peritonitis cases were 2181 and 327 respectively. No reliable data exist on blastomycosis, mucormycosis or fungal keratitis. Over 3% of Tanzanians suffer from serious fungal infections annually, mostly related to HIV. Cryptococcosis and PCP are major causes of mycoses-related deaths. National surveillance of fungal infections is urgently needed.

Abstract
Pneumocystis pneumonia (PcP) is a serious fungal infection among immunocompromised patients. In developed countries, the epidemiology and clinical spectrum of PcP have been clearly defined and well documented. However, in most developing countries, relatively little is known about the prevalence of pneumocystosis. Several articles covering African, Asian and American countries were reviewed in the present study. PcP was identified as a frequent opportunistic infection in AIDS patients from different geographic regions. A trend to an increasing rate of PcP was apparent in developing countries from 2002 to 2010.

Abstract
Pneumocystis pneumonia (PCP) remains the most common opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS). Familiarity with the clinical features of PCP is crucial for prompt diagnosis, even if the patient is unaware of their HIV serostatus. We describe herein the clinical features of 34 episodes in 32 patients with AIDS-associated PCP and review the existing literature. As for symptoms, the frequency of fever, cough, and dyspnea was 74%, 74%, and 65%, respectively, and the complete triad was present in only 14 of the 34 episodes on first examination. Median duration from onset of symptoms until diagnosis was 3 weeks, and AIDS-associated PCP tended to take an insidious clinical course. Although laboratory findings were generally nonspecific, measurement of beta-D-glucan levels in the serum or plasma was highly useful in the diagnosis of PCP. All but 1 of the patients showed beta-D-glucan levels higher than the cutoff value (median, 147 pg/ml; range, 5-6920 pg/ml). Typical radiographic features of PCP are bilateral, symmetrical ground-glass opacities, but a wide variety of radiographic findings were observed. In our patients, high-resolution computed tomography (HRCT) of the lung showed ground-glass opacities sparing the lung periphery (41% of episodes) or displaying a mosaic pattern (29%), or being nearly homogeneous (24%), ground-glass opacities associated with air-space consolidation (21%), associated with cystic formation (21%), associated with linear-reticular opacities (18%), patchily and irregularly distributed (15%), associated with solitary or multiple nodules (9%), and associated with parenchymal cavity lesions (6%).

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-related mortality has decreased because of highly active antiretroviral therapy. As the life expectancy of HIV-infected patients has increased, the management of comorbid disease in such patients has become a more important concern. We examined the level of comfort self-reported by experts in HIV medicine with prescribing medications to HIV-infected patients for hyperlipidemia, diabetes, hypertension, and depression. METHODS As part of a larger project (the Veterans Aging Cohort Study), physicians at infectious diseases (ID) clinics and physicians at general medical (GM) clinics were asked to complete a survey requesting information about demographic characteristics, training and certification received, and self-reported comfort with prescribing medications for patients with hyperlipidemia, diabetes, hypertension, and/or depression. Comfort was rated using a 5-point Likert scale, with scores of 4-5 classified as "comfortable." RESULTS Of 150 attending physicians surveyed, 51 (34%) were ID certified, 33 (22%) were GM certified but practicing at an ID clinic, and 66 were GM certified and practicing at a GM clinic. Comorbid conditions were common among HIV-infected patients treated at the ID clinics (22% of these patients had hyperlipidemia, 17% had diabetes, 40% had hypertension, and 27% had depression). However, comfort with treating these conditions was less among physicians at the ID clinic. For example, comfort treating patients with hyperlipidemia was greater for GM-certified physicians at GM clinics than for GM-certified physicians and ID-certified physicians at ID clinics (98% vs. 73% and 71%, respectively; P < .0001 for trend). A similar pattern was seen for treating patients with diabetes and hypertension (P < .0001). Comfort with treating patients with depression was generally lower, particularly among physicians at ID clinics (P < .0001). CONCLUSIONS We found that ID-certified physicians and GM-certified physicians at ID clinics reported less comfort prescribing medications for common comorbid conditions, compared with generalist physicians at GM clinics, despite a substantial prevalence of these conditions at the ID clinics. Methods are needed to increase physicians' level of comfort for prescribing treatment and/or to facilitate referral to other physicians for treatment.

Abstract
OBJECTIVE To assess the association of specialty training and experience in the care of HIV disease with HIV-specific knowledge, referral patterns, and HIV-related education activities. DESIGN Cross-sectional survey. SETTING The United States. PARTICIPANTS Physicians caring for patients in the HIV Costs and Service Utilization Study, a study of a probability sample of HIV-infected individuals in the United States. MEASUREMENTS AND MAIN RESULTS Measures included physicians' reports of specialty training and HIV caseload, scores on an HIV-specific knowledge test, referral patterns, and attendance rates at HIV-related educational activities. Approximately 72% (379) of the eligible physicians completed a survey. Of these, 152 (40%) had infectious disease (ID) training, and 213 (56%) were generalists; 4% of ID-trained physicians and 37% of generalist physicians did not consider themselves HIV experts. The median current caseloads were 150 and 200 patients for ID experts and generalist experts, respectively. In contrast, the median caseload for non-expert generalists was 5. Mean scores on the knowledge scale were similar for ID and generalist experts (9.0 items correct out of 11 vs 8.5; P=not significant), but lower for generalist non-experts (6.5 items correct; P <.01). Experts had attended more local and national HIV meetings than non-experts (9.3 vs 2.7; P <.01, and 2.3 vs.40; P <.01, respectively) in the past year. Fewer ID experts ever referred than generalist experts (13.0% vs 27.3%; P=.01). In multivariable models that included specialty training and caseload, physicians with caseloads of 20 to 49 and >50 were more likely to have a high knowledge score (defined as 80% or more correct, odds ratio [OR], 2.8; P=.04 and OR, 5.7; P <.001, respectively), and the effect of specialty was attenuated (OR, 2.7; P=.02 decreased from OR, 7.8; P <.001 in a model without caseload). In the models predicting referral practices, both experience (OR,.25; P <.01 and OR,.17; P <.01 for caseloads of 20 to 49 and >50, respectively) and specialty (OR,.19; P <.01 and OR,.09; P <.01 for generalist and ID experts, respectively) were significant. CONCLUSIONS In a national sample of physicians, HIV-specific knowledge was more strongly associated with HIV caseload than with specialty training. In addition, although referral practices were related to both experience and specialty, generalist experts and ID physicians reported similar behaviors. This suggests that generalist physicians, through clinical experience and self-education, can develop specialized knowledge in HIV care.

Abstract
BACKGROUND Controversy exists regarding who should provide care for those with HIV/AIDS. While previous studies have found an association between physician HIV experience and patient outcomes, less is known about the relationship of physician specialty to HIV/AIDS outcomes or quality of care. OBJECTIVE To examine the relationship between choice of appropriate antiretroviral therapy (ART) to physician specialty and HIV/AIDS experience. DESIGN Self-administered physician survey. PARTICIPANTS Random sample of 2,478 internal medicine (IM) and infectious disease (ID) physicians. MEASUREMENTS Choice of guideline-recommended ART. RESULTS Two patients with HIV disease, differing only by CD4+ count and HIV RNA load, were presented. Respondents were asked whether ART was indicated, and if so, what ART regimen they would choose. Respondents' ART choices were categorized as "recommended" or not by Department of Health and Human Services guidelines. Respondents' HIV/AIDS experience was categorized as moderate to high (MOD/HI) or none to low (NO/LO). For Case 1, 72.9% of responding physicians chose recommended ART. Recommended ART was more likely (P <.01) to be chosen by ID physicians (88.2%) than by IM physicians (57.1%). Physicians with MOD/HI experience were also more likely (P <.01) to choose recommended ART than those with NO/LO experience. Finally, choice of ART was examined using logistic regression: specialty and HIV experience were found to be independent predictors of choosing recommended ART (for ID physicians, odds ratio [OR], 4.66; 95% confidence interval [95% CI], 3.15 to 6.90; and for MOD/HI experience, OR, 2.05; 95% CI, 1.33 to 3.16). Results for Case 2 were similar. When the analysis was repeated excluding physicians who indicated they would refer the HIV "patient," specialty and HIV experience were not significant predictors of choosing recommended ART. CONCLUSIONS Guideline-recommended ART appears to be less likely to be chosen by generalists and physicians with less HIV/AIDS experience, although many of these physicians report they would refer these patients in clinical practice. These results lend support to current recommendations for routine expert consultant input in the management of those with HIV/AIDS.

Abstract
PURPOSE To review the literature on the methods used in writing case-specific checklists for studies of internal medicine physicians' performances that were assessed by standardized patients. METHOD The authors searched Medline, Embase, Psychlit, and ERIC for articles in English published between 1966 and February 1998. The following search string was used: "[(standardi(*) or simulat(*) or programm(*)) near (patient(*) or client(*) or consultati(*))] and internal medicine." The authors then searched the reference lists of papers retrieved from the database searches, as well as those from seven proceedings of the International Ottawa Conference on Medical Education and Assessment. RESULTS The procedure yielded 29 relevant articles: database searches yielded 14 published reports dealing with case-specific checklists, 11 articles were culled from the reference lists of these papers, and the Ottawa Conference proceedings yielded four articles. Only 12 articles reported specifically on the development of checklists. In general, there were three sources used for developing checklists: panels of experts, the investigators themselves, and responses from expert physicians to written protocols. No article indicated that researchers had relied exclusively on data from the literature to compose their checklists. Only three articles indicated that literature sources had informed their checklist development. All articles except one relied on explicit criteria for the inclusion of items on the checklists. In 21 of the 29 articles, the checklists had been scored by SPs, but the scoring of specific items on the checklists varied according to the purpose of the SP-physician encounter. Only four of the articles made the checklists available or indicated that the checklists could be obtained from the authors. CONCLUSION The development of case-specific checklists for SP examinations of physicians' performance has received little attention. To judge the validity of studies of physicians' performances that use SPs, the development processes for the checklists need to be more fully described to enable readers to evaluate the validity and reliability of the studies.

Abstract
PURPOSE To assess the effects of physician specialty on the knowledge, management, and outcomes of patients with coronary disease or heart failure. MATERIALS AND METHODS We performed a systematic search of MEDLINE from 1980 to 1997, as well as bibliographic references to articles about the effects of physician specialty on the knowledge, treatment, and outcomes of patients with coronary disease or heart failure in the United States. RESULTS Twenty-four articles met our criteria for inclusion (including eight that involved knowledge or self-reported practices, 14 that described actual practice patterns, and six that measured clinical outcomes). Cardiologists were more knowledgeable than generalist physicians about the optimal evaluation and management of coronary disease but not about the use of angiotensin-converting enzyme (ACE) inhibitors for heart failure. Patients with unstable angina or myocardial infarction were more likely to receive proven medical therapies, and possibly had improved outcomes, if they were treated by cardiologists. The use of lipid-lowering drugs after myocardial infarction was also more common among patients of cardiologists. ACE inhibitor use for heart failure was probably greater, and short-term readmission rates were lower, with cardiology care. CONCLUSIONS Patients with coronary disease or heart failure in the United States who are treated by cardiologists appear more likely to receive evidence-based care and probably have better outcomes. Investigation of collaborative models of care and innovative efforts to improve the use of proven therapies by physicians are needed.

Abstract
Treatment advances and outcomes data have raised new concerns about how to optimize care for patients with HIV infection. This paper reviews evidence on 1) the relation between experience and type of training and patient outcomes, 2) the relation between the components of primary care and patient outcomes, and 3) primary care physicians' basic HIV knowledge and skills in screening and prevention. Several studies indicate that greater experience in HIV care leads to improved patient outcomes. The relation between outcomes and type of training (subspecialist or generalist) is less clear, and studies have not distinguished between type of training and experience. Less experienced physicians may be able to provide high-quality care if appropriate consultation from expert physicians is available. Components of primary care, including accessibility, continuity, coordination, and comprehensiveness, are associated with better patient outcomes. Optimal care of HIV infection requires a combination of disease-specific expertise and primary care skills and organization. Criteria for expertise in HIV management should focus on actual patient care experience and HIV expertise rather than on subspecialty training per se. The management of HIV has become sufficiently complex that primary care physicians cannot be routinely expected to have extensive specialized knowledge in this area. However, many primary care physicians have weaknesses in the basic HIV-related skills that are needed in most settings, such as HIV test counseling and recognition of important HIV-related symptom complexes. Primary care physicians need to strengthen these basic HIV-related medical skills.

Abstract
The willingness of physicians to provide care to HIV-positive patients has been linked to a number of attitudinal factors, but little is known concerning the impact of premedical, medical, and residency training on these factors. The purpose of this study is to elicit responses to the same series of questions concerning HIV and its treatment from respondents at different stages of training, to detect trends in attitudes and to measure the impact of those attitudes on willingness to provide care for HIV/AIDS patients. Study data come from a cross-sectional survey (n = 249) of respondents across the training continuum, from premedical students to faculty physicians, using a self-administered questionnaire at a single medical school. The response rate was 59.6%. The study showed significant decreases in personal fear and misgivings concerning HIV, coupled with a substantial decrease in the perceived need for testing of non-high-risk individuals, as respondents gained additional education and training. Overall, the intent to treat HIV did not change significantly by training level, but multivariate analyses showed that while the initially strong influence of attitudes toward AIDS and its attendant risks diminishes, comfort relative to being around homosexuals per se continues to exert an impact on the intent to treat. Appropriate use of protective measures when providing care becomes far more common once individuals enter their clinical training years. The impact of medical education through its entire continuum therefore shows a positive impact on attitudes toward HIV, despite the absence of a significant trend in respondents' stated intent to treat. However, negative attitudes toward homosexuals continue to exert a negative influence on intent to treat that endures into the clinical training years.

Abstract
STUDY OBJECTIVES To determine whether physician experience and specialty influence the approach to care of AIDS patients with pneumonia, we surveyed physicians about their management of possible Pneumocystis carinii pneumonia (PCP) infection. DESIGN, SETTING, PARTICIPANTS A postal survey was sent to a random sample of 1,500 internists and family physicians in the United States drawn from the American Medical Association master file who were identified by a pharmaceutical marketing company as having written prescriptions for AIDS-related agents in the previous year. MEASUREMENTS AND RESULTS The survey had a 53% response rate. Physicians more experienced in AIDS care were more likely to advocate diagnostic bronchoscopy over initiation of empiric anti-PCP therapy for HIV-infected patients with undiagnosed pulmonary infiltrates (odds ratio [OR], 1.4 for a patient with mild severity of illness [p = 0.02]; OR, 1.7 for a severely ill patient [p < 0.001]). Physician specialty and fee-for-service reimbursement were independently associated with higher rates of bronchoscopy, with internists favoring bronchoscopy more frequently than family physicians. High-experience providers and internists also predicted better clinical outcomes for the hypothetical patients. CONCLUSIONS Our findings extend the observations about HIV experience and PCP prophylaxis to the setting of diagnosis and treatment. Physicians with higher levels of experience with AIDS, internists, and physicians reimbursed as fee-for-service providers are more likely to support diagnostic confirmation of PCP than empiric treatment approaches.

Abstract
Delayed referral (defined as a serum creatinine concentration > 4 mg/dL at referral) of patients with chronic renal failure to the nephrologist is common in the United States. We retrospectively examined the records of 220 consecutive patients referred to an urban teaching hospital nephrology division for evaluation of chronic renal failure from January 1987 to December 1994 to detect any relationship between race, renal diagnosis, or age and the timing of referral of medically-insured patients with chronic renal failure. We documented serum creatinine concentration and hematocrit at referral, length of time under the care of a nephrologist (interval from referral to initiation of dialysis), and total number of clinic visits. The 220 study subjects (120 women, 100 men) included 139 blacks (63%), 61 whites (28%), 16 Hispanics (7%), and 4 Asians (2%) aged 51.7 +/- 1.06 years (mean +/- standard error of the mean) at referral. At referral, nonwhites (black and Hispanic patients) had a greater mean serum creatinine concentration than whites (4.3 +/- 0.38 v 3 +/- 0.24 mg/dL; P = 0.001), as well as a lower mean hematocrit (31.7% +/- 1.3% v 34.7% +/- 0.9%; P = 0.001). Mean length of time under the care of a nephrologist was shorter in nonwhites (13 +/- 0.8 months) than whites (43.5 +/- 4.8 months; P = 0.001). Delayed referral was almost six times more likely in nonwhites than whites (odds ratio, 5.6; 95% confidence interval [CI], 1.52 to 20; P = 0.008) and five times more likely in those aged older than 55 years than in those 55 years or younger (odds ratio, 4. 7; 95% CI, 1.37 to 16; P = 0.01). The greater the serum creatinine concentration at referral, the greater the odds of receiving less than 12 months of nephrologic care before initiation of dialysis (odds ratio, 1.8; 95% CI, 1.04 to 3.13; P = 0.03). We conclude that even among those patients with health insurance, delayed referral to the nephrologist is more likely in black, Hispanic, and older patients with chronic renal failure than in their white or younger counterparts.

Abstract
Provider attitudes and perceptions that may influence recruitment and enrollment of diverse patients into AIDS clinical trials were examined by conducting a cross-sectional survey of all HIV/AIDS providers at a municipal teaching hospital. Providers were less likely to feel confident explaining trials to non-English-speaking patients (p < .05). Providers also reported being more confident of their ability to give an overview of clinical trials in culturally appropriate terms to white patients than to patients of other races/ethnicities (p < .05). Many providers perceived the interest in clinical trials by African American (25%), Latino (14%), and Haitian patients (30%) to be lower; and primarily cited suspicions about clinical research as the reason. Some providers (13%) perceived that women with HIV/AIDS are less interested in clinical trials. Despite these perceptions, all providers reported that they are just as likely to inform women and African Americans about available clinical trials; a small proportion reported that they were less likely to inform Latinos (6%) and Haitians (11%). None of these findings differed significantly by provider race, gender, HIV experience, languages spoken, or specialty. Underrepresentation of minorities and women in AIDS Clinical Trials may partially result from attitudes and perceptions of providers.

Abstract
OBJECTIVE To determine whether intensive care unit (ICU) use and outcomes for patients with human immunodeficiency virus (HIV)-related Pneumocystis carinii pneumonia vary by hospital characteristics and geographic location. DESIGN Retrospective review of the medical records of 2,174 patients with HIV-related P. carinii pneumonia. SETTING Random sample of 73 private, nine public, and 14 Veterans Affairs hospitals in five cities (Chicago, New York, Los Angeles, Miami, and Durham, NC). PATIENTS Stratified random sample of patients hospitalized with HIV-related P. carinii pneumonia from 1987 to 1990. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Among the 2,174 patients with P. carinii pneumonia, 398 (18%) patients received care in an ICU. ICU utilization varied significantly by patient and hospital characteristics, as well by as geographic location. Non-Hispanic whites, patients with Medicaid, and patients with a prior acquired immunodeficiency syndrome-defining illness were the least likely to receive care in an ICU. Patients in county- or state-owned hospitals and patients in hospitals with more P. carinii pneumonia-experience were also less likely to be cared for in an ICU. These differences in ICU utilization persisted when controlling for severity of illness, as well as other patient characteristics. Significant geographic variation in ICU utilization persisted after controlling for patient and hospital characteristics. Survival to hospital discharge after an ICU stay was significantly higher for patients without a prior acquired immunodeficiency syndrome-defining illness and for patients in hospitals with more P. carinii pneumonia experience. CONCLUSIONS We found significant variations in ICU utilization by hospital characteristics and geographic location that remained significant after controlling for severity of illness and patient sociodemographic characteristics. Hospital and geographic variations in ICU utilization may make it difficult to generalize ICU outcomes across different hospitals.

Abstract
BACKGROUND The ability of primary care physicians to obtain important clinical information in initial encounters with new patients is a core competency that has received little attention in previous studies. This paper describes the history-taking and preventive screening skills of practicing primary care physicians in initial interactions with ambulatory patients, as determined by a large panel of standardized patients. METHODS Standardized patient cases with diverse presentations were developed and used to assess the clinical skills of 134 primary care physicians from five Northwest states. Scoring categories for each case identified the percentage and content of essential history items and preventive screening items performed. Physicians' scores were compared by training and practice characteristics. RESULTS Physicians asked 59% of essential history items. They frequently obtained appropriate information about presenting symptoms and medications, but they often missed important information about related symptoms and medical history. Physicians frequently screened for smoking and alcohol use, but rarely asked about recreational drug use. Although board-certified general internists performed more comprehensive histories than board-certified family practitioners in the same amount of time, both groups of providers missed a large number of items that should have been influential in developing diagnostic and treatment plans. CONCLUSIONS Primary care physicians may miss important patient information in their initial interactions with patients. Medical intake questionnaires or other approaches should be considered to ensure that more complete and accurate information is available to guide diagnostic and treatment plans.

Abstract
OBJECTIVE To examine the association of clinic HIV-focused features and advanced HIV care experience with Pneumocystis carinii pneumonia (PCP) prophylaxis and development of PCP as the initial AIDS diagnosis. DESIGN Nonconcurrent prospective study. SETTING New York State Medicaid Program. PARTICIPANTS Medicaid enrollees diagnosed with AIDS in 1990-1992. MEASUREMENTS AND MAIN RESULTS We collected patient clinical and health care data from Medicaid files, conducted telephone interviews of directors of 125 clinics serving as the usual source of care for study patients, and measured AIDS experience as the cumulative number of AIDS patients treated by the study clinics since 1986. Pneumocystis carinii pneumonia prophylaxis in the 6 months before AIDS diagnosis and PCP at AIDS diagnosis were the main outcome measures. Bivariate and multivariate analyses adjusted for clustering of patients within clinics. Of 1,876 HIV-infected persons, 44% had PCP prophylaxis and 38% had primary PCP. Persons on prophylaxis had 20% lower adjusted odds of developing PCP (95% confidence interval [CI] 0.64, 0.99). The adjusted odds of receiving prophylaxis rose monotonically with the number of HIV-focused features offered by the clinic, with threefold higher odds (95% CI 1.6, 5.7) for six versus two or fewer such features. Patients in clinics with three HIV-focused features had 36% lower adjusted odds of PCP than those in clinics with one or none. Neither clinic experience nor specialty had a significant association with prophylaxis or PCP. CONCLUSIONS PCP prevention in our study cohort appears to be more successful in clinics offering an array of HIV-focused features.

Abstract
BACKGROUND Institutional variation in the quality of medical care may be evaluated by examining process measures, such as use of diagnostic procedures or treatment modalities, or outcome measures, such as mortality. We undertook this study to examine variations in both process and outcome of care for patients with HIV-related Pneumocystis carinii pneumonia (PCP) at two geographically diverse, HIV-experienced, public municipal hospitals. DESIGN Retrospective review of hospitalized patients diagnosed as having PCP cared for at two municipal hospitals from 1988 to 1990. At hospital A, charts of all patients diagnosed as having PCP were abstracted (n=209); at hospital B, a random sample of 15% were abstracted (=136). RESULTS Among all hospitalized patients diagnosed as having PCP, the frequency of making a definitive diagnosis of PCP (as opposed to treating empirically) differed markedly at the two hospitals (85% in hospital A vs 26% in hospital B; p<0.001), as did the use of intensive care (18% vs 3%; p<0.001) and "do-not-resuscitate" orders (39% vs 14%; p<0.001), although the timing of starting anti-Pneumocystis medications (89% vs 88% within the first 2 hospital days) and the use of corticosteroids (21% vs 23%) were similar. Despite differences in the process of care, survival rates were similar at the two institutions (75% vs 76%; p=0.8) and remained similar when logistic regression was used to control for demographic variables and severity of illness (odds ratio for survival, hospital B vs A, 1.2 [95% confidence interval, 0.7, 2.0]). The 95% confidence intervals (0.7, 2.0), however, were consistent with a considerable (and clinically significant) disparity in survival (from 30% lower to a twofold higher odds of survival). Sample size calculations showed that a sample of 10 cases in each hospital would be required to detect the observed difference in definitive diagnosis rates (85% vs 26%), but 722 cases in each hospital would be required to detect a relevant difference in mortality. CONCLUSIONS The process of care for hospitalized patients with PCP in these two institutions differed considerably, but the survival rates were not significantly different, even after adjusting for confounding factors. While sample sizes available at the individual institutions were sufficient for evaluation of the process of care, they did not provide the power necessary to evaluate outcomes. Comparisons of outcomes such as mortality between individual hospitals may not have the statistical power to exclude important differences.

Abstract
OBJECTIVE To assess the content and extent of HIV risk assessment by primary care physicians across a diverse panel of patients with unidentified HIV risk behaviors. DESIGN Standardized patient examination to assess primary care physicians' skills at identifying and managing HIV infection and overall clinical skills. In a day of testing, physicians saw 13-16 standardized patients (SPs) with diverse case presentations. In analyses presented here, physician performance was examined with nine SPs who had unidentified risks for HIV, which they offered if asked. SETTING An academic clinic. PARTICIPANTS We randomly selected 134 paid volunteers (general internists and family/general practitioners) after stratifying by specialty, experience caring for patients with HIV infection, and year of medical school graduation. MEASUREMENTS AND MAIN RESULTS Performance at initiating HIV risk screening and identifying patients' HIV risk behaviors were the main outcome measures. Physicians performed variably at HIV risk screening with different patients and across different HIV risk screening topics. Although physicians initiated screening with 60% of patients, they identified only 49% of risk behaviors and included HIV in the differential diagnosis for less than half of at-risk patients. Physicians performed better with cases in which there was a higher probability of HIV infection based on symptoms, but often did not screen at-risk patients without obvious symptoms suggestive of HIV. Board-certified general internists initiated screening and identified risk behaviors with more patients than board-certified family practitioners. Medical school graduation year also influenced performance. CONCLUSIONS Our data suggest that primary care physicians do not routinely perform HIV risk assessments with patients who have risk behaviors for HIV infection. Methods are needed to develop, standardize, and disseminate better screening techniques to identify patients with or at risk of developing HIV infection, such as written HIV risk screening questions for use in medical intake forms.

Abstract
Hospitals are a major provider of medical care for human immunodeficiency virus (HIV)-infected persons. Although utilization and patterns of care profiles in public and private hospitals have been evaluated for acquired immunodeficiency syndrome (AIDS)-related Pneumocystis carinii pneumonia (PCP), one of the most costly and common severe complications of AIDS, information from Veterans Administration (VA) hospitals has not been reported previously. This article reports on inpatient care for PCP patients by obtaining data from VA, private, and public hospitals. Cost and resource utilization data were obtained from reviews of medical records, claims, and provider bills from 26 non-VA hospitals and 18 VA hospitals in 10 cities in the United States. Data on severity of illness, patterns of care, and outcomes for PCP were obtained from medical record reviews from 2,174 PCP cases treated in 82 non-VA and 14 VA hospitals in five U.S. cities. Estimates were made of the average costs and the rates of use of diagnostic tests, anti-PCP medications, and intensive care units for samples of public hospital, private hospital, and VA patients with PCP. With mean charges for a single PCP episode of $14,500 to $16,060, PCP remains one of thea most costly complications of AIDS. Although the severity of PCP illness at admission was greatest at public hospitals, the intensity of care was lowest: for frequency of cytologic diagnosis (48% at public, 62% at VA, and 66% at private hospitals), bronchoscopy (45% at public, 60% at VA, and 66% at private hospitals), and intensive care unit use (11% at public, 22% at VA, and 19% at private hospitals). In-hospital mortality rates for PCP also differed in the three types of hospitals (20% at public, 24% at VA, and 18% at private hospitals). Patterns of PCP care differ among VA, public, and private hospitals. Future studies on the HIV epidemic should include data collected from uniform data sources from VA hospitals, in addition to public and private hospitals, to provide insight on the processes of care and outcomes for HIV-infected persons.
