AIDS mortality rates lower at sites with HIV experience

HIV/AIDS patients are more likely to receive antiretroviral treatment and survive longer if they are treated by providers who have more experience treating the disease. Researchers examined data on more than 7,000 AIDS patients treated in 333 California hospitals to come to that conclusion. Another study discovered that pregnant HIV-infected women were more likely to receive treatment if they were at medical centers which performed HIV clinical trials or at State-funded sites with HIV services for people on Medicaid. Public hospitals had a higher mortality rate than for-profit and nonprofit hospitals. Part of the disparity can be linked to capitation arrangements by insurers that forces physicians to limit the time with HIV patients. In addition, private practice physicians rarely have time to keep up with medical advances related to HIV. HIV/AIDS patients might receive better care when a primary care physician shares efforts with specialists.     

Primary care delivery is associated with greater physician experience and improved survival among persons with AIDS

OBJECTIVE: It has been shown that greater physician experience in the care of persons with AIDS prolongs survival, but how more experienced primary care physicians achieve better outcomes is not known. DESIGN/SETTING/PATIENTS: Retrospective cohort study of HIV-infected patients enrolled in a large staff-model health maintenance organization from 1990 through 1999. MEASUREMENTS: Adjusted odds of medical service delivery and adjusted hazard ratio of death by physician experience level (least, moderate, most) and service utilization. MAIN RESULTS: Primary care delivery by physicians with greater AIDS experience was associated with improved survival. After controlling for disease severity, patients cared for by the most experienced physicians were twice as likely to receive a primary care visit in a given month compared with patients of the least and moderately experienced physicians (P <.01). Patients of the least experienced physicians received the lowest level of outpatient pharmacy and laboratory services (P <.001) and were half as likely to have a specialty care visit compared with patients of the most and moderately experienced physicians (P <.05). Patients who received infrequent primary care visits by the least experienced physicians were 15.3 times more likely to die than patients of the most experienced physicians (P =.02). There was a significant increase in primary care services delivered to the population of HIV-infected patients receiving care in 1999, when highly active antiretroviral therapy (HAART) was in general use, compared with the time period prior to the introduction of HAART. CONCLUSIONS: Primary care delivery by physicians with greater HIV experience contributes to improved patient outcomes.

The effects of implementation of the Agency for Health Care Policy and Research urinary incontinence guidelines in primary care practices

OBJECTIVES: To determine whether a multifaceted intervention based on the Agency for Health Care Policy and Research (AHCPR) Clinical Practice Guidelines for Urinary Incontinence would increase primary care physician screening for and management of urinary incontinence (UI). DESIGN: Group randomized trial, conducted from 1996 to 1997. SETTING: Internal medicine and family medicine community practices. PARTICIPANTS: Forty-one primary care practices, including 57 physicians and their staff and 1,145 patients aged 60 and older. INTERVENTION: Twenty of the 41 primary care practices in North Carolina were randomized to a composite intervention that included a 3-hour continuing medical education accredited course, training in management of UI, patient educational materials, and on-site physician and office support. The remaining 21 practices served as "usual care" controls. Telephone surveys of UI status and quality of life were obtained from 1,145 patients before the intervention. At 1 year, patients and physicians were contacted by telephone and mail to determine the effect of the educational intervention. MEASUREMENTS: Patients completed telephone surveys to assess screening for UI, UI status, treatment interventions, and quality of life. Physicians completed surveys related to UI treatment and practice patterns. RESULTS: Baseline and endpoint telephone surveys were completed by 668 of 1,145 (58%) of patients, who were cared for by 45 physicians (10 internists, 35 family medicine). Physician screening rates for UI were 22% for those patients who did not report UI. UI was reported by 39.5% of patients at baseline, of whom 30% reported being asked about UI by their primary care physician during the study. Rates of assessment and management of existing UI were low in both the control and intervention groups. Additional historical questioning indicated that 54.2% reported that they had ever undergone assessment, including history, urinalysis, or testing, or had had management of their UI by any physician. CONCLUSION: Attempts at increasing screening and management of UI by primary care physicians using the AHCPR standardized guidelines using a multifaceted system of educational and logistical support were not successful. These guidelines may not be the best approach to treating UI in the primary care setting.     

Relation of physician specialty and HIV/AIDS experience to choice of guideline-recommended antiretroviral therapy

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.     

HIV Risk Screening in the Primary Care Setting: Assessment of Physicians' Skills

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. PATIENTS: 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.     

The doctor-patient relationship and HIV-infected patients’ satisfaction with primary care physicians

OBJECTIVE: To assess the extent to which perceptions of specific aspects of the doctor-patient relationship are related to overall satisfaction with primary care physicians among HIV-infected patients. DESIGN: Longitudinal, observational study of HIV-infected persons new to primary HIV care. Data were collected at enrollment and approximately 6 months later by in-person interview. SETTING: Two urban medical centers in the northeastern United States. PARTICIPANTS: Patients seeking primary HIV care for the first time. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was patient-reported satisfaction with a primary care physician measured 6 months after initiating primary HIV care. Patients who were more comfortable discussing personal issues with their physicians (P=.021), who perceived their primary care physicians as more empathetic (P=.001), and who perceived their primary care physicians as more knowledgeble with respect to HIV (P=.002) were significantly more satisfied with their primary care physicians, adjusted for characteristics of the patient and characteristics of primary care. Collectively, specific aspects of the doctor-patient relationship explained 56% of the variation in overall satisfaction with the primary care physician. CONCLUSIONS: Patients’ perceptions of their primary care physician’s HIV knowledge and empathy were highly related to their satisfaction with this physician. Satisfaction among HIV-infected patients was not associated with patients’ sociodemographic characteristics, HIV risk characteristics, alcohol and drug use, health status, quality of life, or concordant patient-physician gender and racial matching. This research was conducted in part in the General Clinical Research Center at Boston University School of Medicine, USPHS grant M01 RR00533.     

Physician surveys to assess customary care in medical malpractice cases

OBJECTIVE: Physician experts hired and prepared by the litigants provide most information on standard of care for medical malpractice cases. Since this information may not be objective or accurate, we examined the feasibility and potential value of surveying community physicians to assess standard of care. DESIGN: Seven physician surveys of mutually exclusive groups of randomly selected physicians. SETTING: Iowa. PARTICIPANTS: Community and academic primary care physicians and relevant specialists. INTERVENTIONS: Included in each survey was a case vignette of a primary care malpractice case and key quotes from medical experts on each side of the case. Surveyed physicians were asked whether the patient should have been referred to a specialist for additional evaluation. The 7 case vignettes included 3 closed medical malpractice cases, 3 modifications of these cases, and 1 active case. MEASUREMENTS AND MAIN RESULTS: Sixty-three percent of 350 community primary care physicians and 51% of 216 community specialists completed the questionnaire. For 3 closed cases, 47%, 78%, and 88% of primary care physician respondents reported that they would have made a different referral decision than the defendant. Referral percentages were minimally affected by modifying patient outcome but substantially changed by modifying patient presentation. Most physicians, even those whose referral decisions were unusual, assumed that other physicians would make similar referral decisions. For each case, at least 65% of the primary care physicians disagreed with the testimony of one of the expert witnesses. In the active case, the response rate was high (71%), and the respondents did not withhold criticism of the defendant doctor. CONCLUSIONS: Randomly selected peer physicians are willing to participate in surveys of medical malpractice cases. The surveys can be used to construct the distribution of physician self-reported practice relevant to a particular malpractice case. This distribution may provide more information about customary practice or standard of care than the opinion of a single physician expert.     

Will commercial managed care patients accept residents as their primary care providers?

We conducted a telephone survey of patients in a university-based medical practice to determine if there was a difference across payer class in patients' willingness to have supervised housestaff physicians function as their primary care providers. Overall, commercial managed care patients were more likely to object to seeing housestaff physicians than were Medicaid or Medicare patients (50% vs 32% or 23%, respectively). However, prior outpatient care by a resident physician significantly increased patient willingness to be cared for by a resident. This effect of prior care by a resident was noted in the managed care as well as the Medicaid and Medicare populations. Although there may have been self-selection, our data demonstrate that a significant proportion of managed care patients who have had residents as their primary care providers are amenable to continuing this practice.     

Clinic Services for Persons with AIDS: Experience in a High-Prevalence State

OBJECTIVE: To profile characteristics of clinics caring for persons with advanced HIV infection. DESIGN AND SETTING: Survey of clinic directors in New York State. PARTICIPANTS: Newly diagnosed Medicaid-enrolled AIDS patients in New York state in federal fiscal years 1987-1992 (n = 6,184) managed by 62 HIV specialty, 53 hospital-based general medicine/primary care, 36 community-based primary care, and 28 other clinics. MEASUREMENTS AND MAIN RESULTS: Telephone survey about clinic hours, emphasis on HIV, staffing, procedures, and directors' rating of care. Estimates of the number of newly diagnosed, Medicaid-enrolled AIDS patients treated in surveyed clinics were obtained from claims data. We found that community-based clinics were significantly more likely to have longer hours, a physician on call, or to accommodate unscheduled care than were hospital-based general medicine/primary care or other types of clinics. Compared with HIV specialty clinics, general medicine/primary care clinics were less likely to have HIV-specific care attributes such as a director of HIV care (98% vs 72%), multidisciplinary conferences on HIV care (83% vs 32%), or a standard initial HIV workup (90% vs 70%). Of general medicine/primary care clinics, most (83%) were staffed by residents and fellows compared with only 68% of HIV or 25% of community-based clinics (p < .001). General medicine/primary care clinics were less likely than community-based clinics to perform Pap smears (75% vs 94%) or to have case managers on payroll (21% vs 81%). CONCLUSIONS: In this sample of clinics, hospital-based general medicine/primary care clinics managing the care of Medicaid enrollees with AIDS appeared to have more limited hours and availability of specific services than HIV specialty or community-based clinics.     

Knowledge and attitudes of physicians in private practice towards HIV/AIDS in Mashhad, Iran

Being responsible for providing care for HIV/AIDS in a society, physicians should be knowledgeable and have favourable attitudes. We designed a cross-sectional study to assess knowledge and attitudes towards HIV/AIDS of private practicing physicians in Mashhad, Iran. A total of 346 general practitioners and specialists completed anonymous self-administered questionnaires with response rate of 91.1%. For knowledge questions, the mean proportion of correct responses was 53.5% (±13.2). Misconceptions about HIV transmission were the main areas of insufficient knowledge. Surprisingly only 20% knew how to manage a patient who had experienced sexual contact with an HIV-positive partner. While 84% disagreed that 'HIV-infected individuals deserved to catch infection' owing to high-risk behaviours, 38% sympathized less with people who were infected via extramarital sex. It seems that knowledge and attitudes towards HIV/AIDS among the studied physicians is not favourable and is an area that requires attention to enable effective management of the disease in Iran.     

HIV primary care by the infectious disease physician in the United States - extending the continuum of care

Models of care for people living with HIV (PLWH) have varied over time due to long term survival, development of HIV-associated non-AIDS conditions, and HIV specific primary care guidelines that differ from those of the general population. The objectives of this study are to assess how often infectious disease (ID) physicians provide primary care for PLWH, assess their practice patterns and barriers in the provision of primary care. We used a 6-item survey electronically distributed to ID physician members of Emerging Infections Network (EIN). Of the 1248 active EIN members, 644 (52%) responded to the survey. Among the 644 respondents, 431 (67%) treated PLWH. Of these 431 responders, 326 (75%) acted as their primary care physicians. Responders who reported always/mostly performing a screening assessment as recommended per guidelines were: (1) Screening specific to HIV (tuberculosis 95%, genital chlamydia/gonorrhoea 77%, hepatitis C 67%, extra genital chlamydia/gonorrhoea 47%, baseline anal PAP smear for women 36% and men 34%); (2) Primary care related screening (fasting lipids 95%, colonoscopy 95%, mammogram 90%, cervical PAP smears 88%, depression 57%, osteoporosis in postmenopausal women 55% and men >50 yrs 33%). Respondents who worked in university hospitals, had <5 years of ID experience, and those who cared for more PLWH were most likely to provide primary care to all or most of their patients. Common barriers reported include: refusal by patient (72%), non-adherence to HIV medications (43%), other health priorities (44%), time constraints during clinic visit (43%) and financial/insurance limitations (40%). Most ID physicians act as primary care providers for their HIV infected patients especially if they are recent ID graduates and work in university hospitals. Current screening rates are suboptimal. Interventions to increase screening practices and to decrease barriers are urgently needed to address the needs of the aging HIV population in the United States.     

Inquiry about victimization experiences. A survey of patient preferences and physician practices.

BACKGROUND--It is unknown whether patients want primary care physicians to inquire about physical abuse (PA) or sexual abuse (SA) or how frequently physicians make such inquiries. METHODS--To determine patient preferences and physician practices, we surveyed 164 patients and 27 physicians at private and public primary care sites. Data were collected using confidential, anonymous, written, multiple-choice questionnaires and were evaluated using univariate analysis. RESULTS--Among patients, routine PA inquiry was favored by 78% and routine SA inquiry was favored by 68%. Only 7% were ever asked about PA and 6% about SA. A history of PA was reported by 16% and a history of SA by 17%. Ninety percent believed physicians could help with problems from PA and 89% felt physicians could help with problems from SA. Among physicians, one third believed that PA and SA questions should be asked routinely. However, SA inquiries were never made by 89% at initial visits or by 85% at annual visits. Physical abuse inquiries were never made by 67% at initial visits, or by 60% at annual visits. Eighty-one percent believed they could help with problems associated with PA and 74% with SA. CONCLUSIONS--Most patients favor inquiries about physical and sexual abuse and believe physicians can help with these problems. Physicians believe they can help with these problems though they frequently do not inquire.     

Experience in treating persons with HIV/AIDS and the legalization of assisted suicide: the views of Canadian physicians

The objective of this study is to determine the opinions of a random sample of Canadian family physicians and a population of non-specialist physicians known to provide care to persons with HIV/AIDS about the legalization of physician assisted suicide for persons with HIV disease. In addition, we have attempted to ascertain the physician characteristics that may be associated with a favourable or negative opinion. Self-administered, anonymous questionnaires were mailed to 2,890 family physicians across Canada. Logistic regression analysis was used to determine whether physician characteristics were predictive of agreement with the legalization of physician assisted suicide. Of the respondents who had an opinion, 60% agreed with the legalization of physician assisted suicide. Multivariate analyses indicated that physicians who were living in the provinces of British Columbia (BC), Ontario, or Québec (OR = 1.63, 95% CI: 1.10, 2.43) and who provided routine follow-up care (OR = 1.85, 95% CI: 1.30, 2.63) or palliative care (OR 1.66, 95% CI: 1.13, 2.44) to those with HIV disease were more likely to agree with legalization of physician assisted suicide. This analysis demonstrates a strong support for the legalization of physician assisted suicide for persons with HIV disease among physicians experienced in providing care to those affected.     

Telephone reporting of the results of cardiac procedures: feasibility and primary care physician preferences.

PURPOSE: We evaluated the feasibility and time required for routine telephone communication with primary care physicians after cardiac procedures and surveyed primary care physicians as to their preferences for the method and content of reports of cardiac procedures. SUBJECTS AND METHODS: A phone call was made within 1 day of the procedure during normal working hours to the primary care physician for all 414 patients who underwent cardiac catheterizations or interventions during a 1-year period. Subsequently, all 211 primary care physicians were mailed a questionnaire on the effectiveness of phone calls as compared with other communication methods. RESULTS: The primary care physician was reached with one call for 51% of patients and could not be contacted with up to five calls to office, clinic, or hospital for 32% of patients. Mean (+/- SD) phone time per patient was 4.1 (+/- 2.0) minutes. Surveys were returned by 119 (56%) of 211 referring physicians. Telephone communication was rated as "very helpful" by 69%. Most primary care physicians (86%) were "very" or "a little pleased" to receive phone calls. Survey respondents identified the summary of the results and the recommendations for treatment as the most important parts of the report. Respondents preferred personal phone calls or faxed reports to phone messages left with office staff, reports sent by electronic mail, or mailed written reports. CONCLUSIONS: Most primary care physicians find personal phone calls helpful and desirable, but the effectiveness of routine phone calls is limited by the availability of primary care physicians during working hours and the time required for phonereporting.     

Early Appointment Adherence Among Persons Living with HIV

Medical care for HIV disease may be most effective when medical surveillance and services are initiated early and consistently maintained over time. To benefit from continually improving HIV care regimens, persons living with HIV/AIDS must first adhere to their outpatient medical appointments. The purpose of this study was to examine psychosocial, illness, and demographic factors associated with appointment adherence problems early in HIV treatment. Results indicated that nonadherence to outpatient medical appointments was a significant problem. One hundred forty-four patients were followed for 6 months after their initial appointment at a public HIV clinic. One in five dropped out of treatment before completing their intake assessment (separate nurse and physician appointments). Men and individuals with lower levels of social support were most likely to drop out before seeing a physician. Emotional distress was not associated with early dropout, but elevated levels of anxiety and depression were found across the sample. Those still attending the clinic (n = 114) were then followed for 12 months after clinic enrollment. Overall, 35% of scheduled medical appointments were missed during this period. Higher baseline CD4 counts and injection drug use history were predictive of poor appointment adherence, but other demographic and psychosocial indices were not. These findings suggest increased research and early intervention efforts are needed to improve appointment adherence among persons living with HIV/AIDS.
