Repeated emergency department (ED) visits by HIV-infected persons may signify poor access to care or treatment from inexperienced ambulatory providers. We examined features of 157 clinics following 6820 HIV-infected patients and associations with repeated (> or =2) ED visits by these patients in the year before their first AIDS diagnosis. Patient clinical and health care data came from 1987-1992 New York State (NYS) Medicaid files and clinic data came from interviews of clinic directors. The HIV/AIDS experience of each study patient's clinic was measured as the annual number of Medicaid enrollees newly diagnosed with AIDS who were contemporaneously followed by the patient's clinic. Repeated ED use was observed for 24%. The adjusted odds ratio (AOR) of repeated ED visits was reduced for patients in clinics with a physician on-call (0.77; 95% confidence interval [CI] = 0.65, 0.92), evening or weekend clinic hours (0.77; 95% CI = 0.64, 0.93), or >50 AIDS patients/year in 1987-1988 (0.56; 95% CI = 0.44, 0.71) versus fewer patients in those years. Patients in clinics with more than one feature promoting accessibility or HIV expertise had a greater reduction in their AOR of repeated ED use. HIV-infected patients in clinics with greater accessibility and HIV expertise rely less on the ED for care. To assess whether community-based care delivered by people living with HIV/AIDS (PLWAs) could replace clinic-based HIV care.
                Prospective cluster randomized controlled clinical trial.
                Villages surrounding 1 rural clinic in western Kenya.
                HIV-infected adults clinically stable on antiretroviral therapy (ART).
                The intervention group received monthly Personal Digital Assistant supported home assessments by PLWAs with clinic appointments every 3 months. The control group received standard of care monthly clinic visits.
                Viral load, CD4 count, Karnofsky score, stability of ART regimen, opportunistic infections, pregnancies, and number of clinic visits.
                After 1 year, there were no significant intervention-control differences with regard to detectable viral load, mean CD4 count, decline in Karnofsky score, change in ART regimen, new opportunistic infection, or pregnancy rate. Intervention patients made half as many clinic visits as did controls (P < 0.001).
                Community-based care by PLWAs resulted in similar clinical outcomes as usual care but with half the number of clinic visits. This pilot study suggests that task-shifting and mobile technologies can deliver safe and effective community-based care to PLWAs, expediting ART rollout and increasing access to treatment while expanding the capacity of health care institutions in resource-constrained environments. The World Health Organization (WHO) recommends shifting tasks from physicians to lower cadres for the delivery of antiretroviral treatment (ART) for countries short of physicians. Our objective was to evaluate the effectiveness and acceptability of ART delivery by health officers and nurses in Ethiopia.
                A retrospective cohort study to evaluate outcomes of ART services in 25 health centres staffed with health officers and/or nurses and 30 hospitals staffed with physicians in 2009. Median CD4-cell counts, mortality, loss to follow-up and retention were the primary outcomes. Interviews and focus group discussions were conducted with people living with HIV/AIDS, AIDS programme managers and health care providers to identify the types and acceptability of the tasks conducted by the health officers, nurses and community health workers.
                Health officers and nurses were providing ART, including ART prescription, for non-severe cases. The management of severe cases was exclusively the task of physicians. Community health workers were involved in adherence counselling and defaulter tracing. The baseline median CD4-cell counts per micro-liter of blood were 117 (interquartiles [IQ] 64,188) and 119 (IQ 67,190) at health centres and hospitals respectively. After 24 months on ART, the median CD4-cell counts per micro-liter of blood increased to 321 (IQ 242, 414) and 301 (IQ 217, 411) at health centres and hospitals respectively. Retention in care was higher in health centres (76%, 95% confidence interval [CI] [73%-79%]) than hospitals (67%, 95% CI [66%-68%]). This difference is mainly due to the higher loss to follow-up rate in hospitals (25% versus 13%). Mortality was higher in health centres than hospitals (11% versus 8%), but the difference is not statistically significant. Service delivery by non-physicians was accepted by patients, health care providers and programme managers. However, the absence of a regulatory framework for task shifting, the lack of extra remuneration for the additional roles assumed by nurses and health officers, and the high cost for training and mentorship were identified as weaknesses.
                ART delivery in health centres, based on health officers and nurses is feasible, effective and acceptable in Ethiopia. However, issues related to regulation, remuneration and cost need to be addressed for the sustainable implementation of these delivery models. To develop and evaluate a model of health care for HIV positive patients involving specialist, hospital based teams and primary health care teams.
                One year retrospective and a 2 1/2 year prospective study.
                Two hospitals in West London and 88 general practitioners in 72 general hospitals.
                209 adults with HIV infection.
                General practitioners enrolled in the project were faxed structured outpatient clinic summaries. When hospital inpatients were discharged, a brief discharge summary was faxed. General practitioners had access to consultant physicians skilled in HIV medicine through a 24 hour mobile telephone service. An HIV/AIDS management and treatment guide containing relevant local information was produced. Quarterly discussion forums for general practitioners were held, and a regular newsletter was produced.
                Hospital attendance and general practitioner consultations; perceived benefits and problems of patients and general practitioners.
                The average length of a hospital inpatient stay was halved for those patients who had participated in the project for two years, and the average number of visits to the outpatient clinic per month fell for patients with AIDS. There was a substantial increase in the number of visits to general practitioners by patients with AIDS and symptomatic HIV infection. Patients and general practitioners both felt that the standard of health care provided had improved.
                This model of health care efficiently and effectively utilised existing teams of hospital and primary health care professionals to provide care for HIV positive patients. Simple, prompt, and regular communication systems which provided information relevant to the needs of general practitioners were central to its success. To test the efficacy of brief, safer-sex counseling by medical providers of HIV-positive patients during medical visits.
                Six HIV clinics in California.
                Clinics were randomized to intervention arms evaluated with cohorts of randomly selected patients measured before and after the intervention.
                Five-hundred and eighty-five HIV-positive persons, sexually active prior to enrollment.
                Prevention counseling from medical providers supplemented with written information. Two clinics used a gain-framed approach (positive consequences of safer-sex), two used a loss-frame approach (negative consequences of unsafe sex), and two were attention-control clinics (medication adherence). Interventions were given to all patients who attended the clinics.
                Self-reported unprotected anal or vaginal intercourse (UAV).
                Among participants who had two or more sex partners at baseline, UAV was reduced 38% (P < 0.001) among those who received the loss-frame intervention. UAV at follow-up was significantly lower in the loss-frame arm [odds ratio (OR), 0.42; 95% confidence interval (CI), 0.19-0.91; P = 0.03] compared with the control arm. Using generalized estimating equations (GEE) to adjust for clustering did not change the conclusions (OR, 0.34; 95% CI, 0.24-0.49; P = 0.0001). Similar results were obtained in participants with casual partners at baseline. No effects were seen in participants with only one partner or only a main partner at baseline. No significant changes were seen in the gain-frame arm.
                Brief provider counseling emphasizing the negative consequences of unsafe sex can reduce HIV transmission behaviors in HIV-positive patients presenting with risky behavioral profiles. There is debate over the types of physicians who should treat patients with complex chronic medical conditions such as human immunodeficiency virus (HIV) infection. We sought to assess the relationship between specialty training and expertise and the quality of care delivered to patients with HIV infection.
                We selected random samples of HIV-infected patients receiving care at 64 Ryan White CARE (Comprehensive AIDS Resources Emergency) Act-funded clinics throughout the country and their primary HIV physicians for an observational cohort study in which quality-of-care measures were assessed by medical record review.
                We studied 5247 patients linked to 177 physicians who responded to a survey. Fifty-eight percent of the physicians were general medicine physicians ("generalists") and 42% were infectious diseases specialists. Sixty-three percent of the generalists (37% overall) considered themselves expert in HIV care. In hierarchical logistic regression models that controlled for patient characteristics, infectious diseases physicians and expert generalists had similar performance. In contrast, nonexpert generalists delivered lower quality care. More than 80% of the appropriate patients being cared for by infectious diseases physicians and expert generalists were receiving highly active antiretroviral therapy, compared with 73% of appropriate patients of nonexpert generalists (P<.001). Physicians with fewer than 20 patients with active HIV had fewer appropriate patients on highly active antiretroviral therapy (73% vs 82% of physicians with >/=20 such patients, P = .04) and saw patients less frequently.
                These findings extend previous work by examining a range of quality-of-care measures and suggest that generalists with appropriate experience and expertise in HIV care can provide high-quality care to patients with this complex chronic illness. In a random assignment study, substance-abusing patients with HIV/AIDS in a public general hospital received a brief contact condition or received 12 months of case management delivered by paraprofessionals. Patient outcomes included substance use, HIV transmission risk, physical health, psychological status, and quality of living situation. In both conditions, a significant decrease occurred in a range of problems from Intake to the 6-month interview, followed by no significant pattern of change at 12- and 18-month interviews. On major outcome variables, there were no significant differences between the brief contact and case management conditions. Sixteen percent had died by the 18-month interview. Process data indicated wide variation in the amount of case management received by participants, and the amount of case management was not related to improvement in the outcome measures. The study has limitations yet does not support the hypothesis that case management improves outcomes better than brief contact for this population. Since the introduction of the first protease inhibitor in January 1996, there has been a dramatic change in the treatment of persons infected with HIV. The changing nature of HIV care has important implications for the types of physicians that can best care for patients with HIV infection.
                To assess the association of specialty training and experience in the care of HIV disease with the adoption and use of highly active antiretroviral (ARV) therapy (HAART).
                Observational cohort study of patients under care for HIV infection and their physicians.
                This analysis used data collected from a national probability sample of noninstitutionalized persons with HIV infection participating in the HIV Costs and Service Utilization Study and their primary physicians. We analyzed 1,820 patients being cared for by 374 physicians.
                Rates of HAART use at 12 months and 18 months after the approval of the first protease inhibitor.
                Forty percent of the physicians were formally trained in infectious diseases (ID), 38% were general medicine physicians with self-reported expertise in the care of HIV, and 22% were general medicine physicians without self-reported expertise in the care of HIV. The majority of physicians (69%) reported a current HIV caseload of 50 patients or more. In multivariable models controlling for patient characteristics, there were no differences between generalist experts and ID physicians in rates of HAART use in December 1996. When compared to ID physicians, however, patients being treated by non-expert general medicine physicians were less likely to be on HAART (odds ratio [OR], 0.32; 95% confidence interval [95% CI], 0.17 to 0.61). Patients being treated by low-volume physicians were also much less likely to be on HAART therapy than those treated by high-volume physicians (OR, 0.26; 95% CI, 0.14 to 0.48). These findings were attenuated by June 1997, suggesting that over time, the broader physician community successfully adopted HAART therapy. This finding is consistent with prior research on the diffusion of innovations.
                Similar proportions of patients treated by expert generalists and ID specialists were on appropriate HAART therapy by December 1996 and July 1997. Patients treated by non-expert generalists, most of whom were the lowest-volume physicians, were much less likely to be on appropriate ARV therapy in the earlier time period. Our findings demonstrate that expert generalists who develop specialized expertise are able to provide care of quality comparable to that of specialists. To evaluate the acceptability, practicality, and short-term efficacy of a health education program to improve disease self-management in patients with symptomatic HIV/AIDS.
                Randomized controlled trial, baseline and 3-month follow-up questionnaire assessments.
                San Francisco Bay communities.
                Seventy-one men with symptomatic HIV or AIDS were randomly assigned to a seven-session group educational intervention (N=34) or a usual-care control group (N=37).
                Interactive health education groups were used to teach wide-ranging disease self-management skills and information: symptom assessment and management, medication use, physical exercise, relaxation, doctor-patient communication, and nutrition. Each group was led by two trained peer-leaders (one of whom was HIV-positive) recruited from the community.
                The primary outcome of interest was symptom status. Secondary outcomes were self-efficacy and health behaviors. Analysis of covariance was used to compare experimental and control group mean outcomes, adjusting for baseline value differences.
                The symptom severity index (number of symptoms moderate or greater severity) decreased in the experimental, and increased in the control group (-0.9 versus +0.5; p < .03). Pain, fatigue, and psychological symptoms were not significantly different between groups. Self-efficacy for controlling symptoms improved in the experimental, and decreased in the control group (+4 versus -7; p < .02). Changes in stress/relaxation exercises and HIV/AIDS knowledge were not different between groups. A trend was shown toward more frequent physical exercise in the experimental group compared with less in the control group (+1.3 versus -0.5 times/week; p=.06).
                Health education emphasizing self-management skills for HIV/AIDS patients can be implemented and evaluated and was accepted by patients, peer-leaders, and health care providers. Whether this educational program can lead to prolonged improvement in HIV symptoms and behaviors can be adequately addressed only by a larger trial of longer duration.
The results demonstrate improved medical outcomes when treated by a provider with more training/expertise in HIV/AIDS care in the outpatient (clinic) setting. Since all of these studies were conducted in North America, this does not address any issues regarding the level of training/expertise required by providers working in countries with more limited resources. Practitioners who do not consider themselves 'experts' in HIV/AIDS care and care for few of these patients need to seriously consider this review which demonstrates a trend towards worse patient outcomes when receiving care by those with low caseloads/training in HIV/AIDS care.
