The variability and predictors of quality of AIDS care services in Brazil

Abstract Background Since establishing universal free access to antiretroviral therapy in 1996, the Brazilian Health System has increased the number of centers providing HIV/AIDS outpatient care from 33 to 540. There had been no formal monitoring of the quality of these services until a survey of 336 AIDS health centers across 7 Brazilian states was undertaken in 2002. Managers of the services were asked to assess their clinics according to parameters of service inputs and service delivery processes. This report analyzes the survey results and identifies predictors of the overall quality of service delivery. Methods The survey involved completion of a multiple-choice questionnaire comprising 107 parameters of service inputs and processes of delivering care, with responses assessed according to their likely impact on service quality using a 3-point scale. K-means clustering was used to group these services according to their scored responses. Logistic regression analysis was performed to identify predictors of high service quality. Results The questionnaire was completed by 95.8% (322) of the managers of the sites surveyed. Most sites scored about 50% of the benchmark expectation. K-means clustering analysis identified four quality levels within which services could be grouped: 76 services (24%) were classed as level 1 (best), 53 (16%) as level 2 (medium), 113 (35%) as level 3 (poor), and 80 (25%) as level 4 (very poor). Parameters of service delivery processes were more important than those relating to service inputs for determining the quality classification. Predictors of quality services included larger care sites, specialization for HIV/AIDS, and location within large municipalities. Conclusion The survey demonstrated highly variable levels of HIV/AIDS service quality across the sites. Many sites were found to have deficiencies in the processes of service delivery processes that could benefit from quality improvement initiatives. These findings could have implications for how HIV/AIDS services are planned in Brazil to achieve quality standards, such as for where service sites should be located, their size and staffing requirements. A set of service delivery indicators has been identified that could be used for routine monitoring of HIV/AIDS service delivery for HIV/AIDS in Brazil (and potentially in other similar settings). </jats:sec

Racial and Ethnic Disparities in Access to Physicians with HIV-related Expertise: Findings from a Nationally Representative Study

OBJECTIVE: Professional medical associations recommend that physicians who treat patients with human immunodeficiency virus (HIV) have a measurable form of disease-specific expertise, such as high HIV patient volume or infectious diseases certification. Although it is known that racial/ethnic minorities generally have worse access to care than do whites, previous work has not examined disparities in the use of physicians with HIV-related expertise. DESIGN, SETTING, AND PARTICIPANTS: We linked data from a prospective cohort study of 2,207 persons with HIV receiving care in the United States with a cross-sectional survey of 404 physicians caring for them. Using multivariate analysis, we estimated the association of patient race/ethnicity with the experience and training of their physicians, controlling for health status, socioeconomic status, demographic characteristics, and geographic variation in provider supply. RESULTS: Compared with white patients, African Americans were less likely to have an infectious diseases specialist as a regular source of care (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.37 to 0.95). Persons of Alaskan Native, American Indian, Asian, Pacific Islander, or mixed racial background were also less likely than whites to have an infectious diseases specialist (OR, 0.44; 95% CI, 0.23 to 0.83). Conversely, Latino patients had physicians whose HIV patient volume was, on average, 24% higher than the physicians of white patients (incident rate ratio, 1.24; 95% CI, 1.03 to 1.50). CONCLUSIONS: Some groups of racial/ethnic minorities are less likely than are whites to have infectious diseases specialists as a regular source of care. The finding that the physicians of Latino patients had relatively higher HIV caseloads suggests that this particular patient subpopulation has access to HIV expertise. Further work to explain racial/ethnic differences in access to physicians will help in the design of programs and policies to eliminate them

Clinic HIV-Focused Features and Prevention of Pneumocystis Carinii Pneumonia

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

Primary Care for Patients Infected with Human Immunodeficiency Virus: A Randomized Controlled Trial

OBJECTIVE: To measure the impact of a teaching intervention and to compare process and outcomes of care for HIV-infected patients randomly assigned to a general medicine clinic (GMC) or an infectious disease clinic (IDC) for primary care. DESIGN: Prospective, randomized, controlled trial. SETTING: University hospital in Durham, NC. PATIENTS: Two hundred fourteen consecutive HIV-infected patients presenting for primary care. INTERVENTION: Physicians at the GMC received HIV-related training and evidence-based practice guidelines. MEASUREMENTS: Utilization of services, health-related quality of life, preventive and screening measures, and antiretroviral use for one year. RESULTS: At baseline GMC patients were more likely to be African American (85% vs 71%; P = .03) and had lower baseline CD4+ cell counts than IDC patients (262 ± 269 vs 329 ± 275; P = .05). A similar and high proportion of patients in both groups received appropriate preventive care services including Pneumocystis carinii pneumonia (PCP) prophylaxis, pneumococcal vaccination, and antiretroviral therapy. Screening for TB was more frequent in GMC (89% vs 68%; P = .001). In the year following randomization, GMC patients made more visits to the emergency department than IDC patients (1.6 ± 3.0 vs 0.7 ± 1.5; P = .05). Hospital use was higher for GMC patients with average length of stay 7.8 ± 6.3 days compared to 5.7 ± 3.8 days for IDC patients (P = .01). In analyses, which adjust for potential baseline imbalances, these differences remained. CONCLUSIONS: Targeted education in GMC achieved similar provision of primary care for GMC patients, yet use of health care services was higher for this group. The delivery of adequate primary care is necessary but not sufficient to produce changes in health care utilization

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

Avaliação da estrutura organizacional da assistência ambulatorial em HIV/Aids no Brasil Evaluation of the organizational structure of HIV/AIDS outpatient care in Brazil

OBJETIVO: No contexto de acesso universal à terapia antiretroviral, os resultados do Programa de Aids dependem da qualidade do cuidado prestado. O objetivo do estudo foi avaliar a qualidade do cuidado dos serviços ambulatoriais que assistem pacientes de Aids. MÉTODOS: Estudo realizado em sete Estados brasileiros, em 2001 e 2002. Foi avaliada a qualidade do atendimento a pacientes com Aids quanto à disponibilidade de recursos e a organização do trabalho de assistência. Um questionário com 112 questões estruturadas abordando esses aspectos, foi enviado a 336 serviços. RESULTADOS: A taxa de resposta foi de 95,8% (322). Os indicadores de disponibilidade de recursos mostram uma adequação maior do que os indicadores de organização do trabalho. Não faltam antiretrovirais em 95,5% dos serviços, os exames de CD4 e Carga Viral estão disponíveis em quantidade adequada em 59 e 41% dos serviços, respectivamente. Em 90,4% dos serviços há pelo menos um profissional não médico (psicólogo, enfermeiro ou assistente social). Quanto à organização, 80% não agendavam consulta médica com hora marcada; 40,4% agendavam mais que 10 consultas médicas por período; 17% não possuíam gerentes exclusivos na assistência e 68,6% não realizavam reuniões sistemáticas de trabalho com a equipe. CONCLUSÕES: Os resultados apontam que além de garantir a distribuição mais homogênea de recursos, o programa precisa investir no treinamento e disseminação do manejo do cuidado, conforme evidenciado nos resultados da organização de trabalho.<br>OBJECTIVE: In the context of universal access to antiretroviral treatment, the results of the Brazilian AIDS Program will depend on the quality of the care provided. The aim of the present study was to evaluate the healthcare provided by outpatient services for the treatment of AIDS patients. METHODS: The present study was carried out in seven Brazilian States between 2001 and 2002. We evaluated the quality of the care provided to AIDS patients from the standpoint of resource availability and care process organization. A questionnaire comprising 112 structured questions addressing these aspects was sent to 336 services. RESULTS: Response rate was 95.8% (322). Greater adequacy is seen for indicators of resource availability than for those of work organization. The supply of antiretroviral medication is sufficient in 95.5% of services. CD4 and viral load tests are available at adequate amounts in 59 and 41% of services, respectively. In 90.4% of services there is at least one non-medical professional (psychologist, nurse, or social worker). As to work organization, 80% scheduled the date but not the time of medical appointments; 40.4% scheduled more than 10 appointments per period; 17% did not have exclusive managers; and 68.6% did not hold systematic staff meetings. CONCLUSIONS: The results indicate that, in addition to ensuring the more homogeneous distribution of resources, the program must invest in the training and dissemination of care management skills, as confirmed by the results of care process organization
