Delivering HIV services to vulnerable populations: a review of CARE Act–funded research

Social services utilization and need among a community sample of persons living with HIV in the rural south

HIV prevalence has increased faster in the southern USA than in other areas, and persons living with HIV (PLWHIV) in the south are often rural, impoverished, or otherwise under-resourced. Studies of urban PLWHIV and those receiving medical care suggest that use of social services can enhance quality of life and some medical outcomes, but little is known about patterns of social service utilization and need among rural southern PLWHIV. The AIDS Alabama needs assessment survey, conducted in 2007, sampled a diverse community cohort of 476 adult PLWHIV representative of the HIV-positive population in Alabama (66% male, 76% Black, and 26% less than high school education). We developed service utilization/need (SUN) scores for each of 14 social services, and used regression models to determine demographic predictors of those most likely to need each service. We then conducted an exploratory factor analysis to determine whether certain services clustered together for the sample. Case management, assistance obtaining medical care, and financial assistance were most commonly used or needed by respondents. Black respondents were more likely to have higher SUN scores for alcohol treatment and for assistance with employment, housing, food, financial, and pharmacy needs; respondents without spousal or partner relationships had higher SUN scores for substance use treatment. Female respondents were more likely to have higher SUN scores for childcare assistance. Black respondents and unemployed respondents were more likely to have SUN scores in the highest quartile of the overall score distribution. Factor analysis yielded three main factors: basic needs, substance use treatment, and legal/medical needs. These data provide important information about rural southern PLWHIV and their needs for ancillary services. They also suggest clusters of service needs that often occur among PLWHIV, which may help case managers and other service providers work proactively to identify important gaps in care.

Access to antiretroviral therapy among HIV/AIDS patients in khon kaen province, Thailand

This study attempted to identify the factors associated with the access to antiretroviral therapy (ARV) among HIV/AIDS patients in Khon Kaen Province, Thailand. We collected medical and sociodemographic data from the medical charts of adult patients living in the province who received medical services at two public hospitals in the province. The study period was from December 1, 2001 to February 28, 2002. Total 593 outpatients were included in the analysis. One hundred and forty-six patients (24.6%) received ARV. A logistic regression analysis was conducted to identify the factors associated with the use of ARV. Patients who were covered by the Civil Servant Medical Benefit Scheme were significantly more likely to receive ARV than those who were covered by the Universal Coverage Scheme (UC), a publicly-funded medical insurance (OR = 12.43; 95% CI = 6.03-25.62). The results of this study indicated that there were inequalities in access to and use of ARV among HIV/AIDS patients by health insurance status. The current government announced that they would include ARV in the benefits package of UC. It would be important to monitor how this policy will improve the access to ARV among HIV/AIDS patients.

Expanding the lens of HIV services provision in Canada: results of a national survey of HIV health professionals

Those living with HIV may experience a range of disabilities, including body impairments, activity limitations, and social participation restrictions. The aim of this study was to examine HIV services provision in Canada by exploring practices, referrals, and service delivery challenges from the perspective of HIV health professionals (including nurses, physicians, social workers, pharmacists, psychologists, and dieticians), and to explore differences in referrals and perceived service delivery challenges by professional group, jurisdiction, community size, and practice in a Northern region. We conducted a nationwide mail survey with the population of selected HIV health professionals in Canada using the Dillman tailored design survey method. Of the 731 deliverable mailings, we received 462 (63%) responses, with 36% of eligible respondents completing the survey (n=214). The large majority (90%) of HIV professionals were located in metropolitan or urban communities and worked predominantly in hospital in-patient (42%), out-patient (50%), and HIV specialty clinic (46%) settings in one of the three provinces (Ontario, Quebec, and British Columbia) with the highest HIV prevalence. HIV health professionals referred primarily, and at relatively high levels, to AIDS service organizations (79%) and social workers (84%) to address participation restrictions and social issues; a lower percentage referred to rehabilitation professionals and other service providers to address impairments, activity limitations, or participation restrictions. Of respondents, 74% perceived barriers to care specific to HIV. Our results suggest that there is little difference in referral patterns by profession, jurisdiction, community size, or northern region of practice. There is a need for increased information and education of HIV health professionals that may refer to rehabilitation and other health services. In addition, new approaches are needed to coordinate multisectoral care and enhance the access and delivery of HIV rehabilitation health services to better meet the disablement needs of people living with HIV in Canada.

Does self-report data on HIV primary care utilization agree with medical record data for socially marginalized populations in the United States?

To test whether self-report data agree with medical record data in marginalized, HIV-infected populations, we collected information about HIV primary care visits over a 6-month period from both sources. Patients were drawn from a large study of engagement and retention in care conducted between 2003 and 2005. Self-report data were collected in face-to-face interviews and medical records were extracted using a rigorous, standardized protocol with multiple quality checks. We found poor overall agreement (weighted kappa = 0.36, 95% confidence interval = 0.28, 0.43). Factors associated with disagreement included younger age (adjusted odds ratio for 20 versus 40 years = 1.25, 95% confidence interval = 0.98, 1.60), non-Hispanic black race/ethnicity (adjusted odds ratio for non-Hispanic blacks versus non-Hispanic whites = 1.48, 95% confidence interval = 1.03, 2.13), lower education (adjusted odds ratio for high school education, GED, or less versus some college or college graduate = 1.43, 95% confidence interval = 0.96, 2.13), and substance use (adjusted odds ratio for any illicit drug/heavy alcohol use in the past 6 months versus no use = 1.39, 95% confidence interval = 1.02, 1.90). These findings do not support a conclusion that unconfirmed self-report data of HIV primary care visits are a sufficient substitute for rigorously collected medical record data in studies focusing on marginalized populations. Use of other data sources (e.g., administrative data), use of other self-reported outcome measures that have better concordance with medical records/administrative data (e.g., CD4 counts), or incorporation of rigorous measures to increase reliability of self-report data may be needed. Limitations of this study include the lack of a true gold standard with which to compare self-report data.

Utilization of health care services in hard-to-reach marginalized HIV-infected individuals

To benefit from HIV treatment advances individuals must utilize ambulatory primary care services. Few studies focus on marginalized populations, which tend to have poor health care utilization patterns. This study examined factors associated with health care utilization in hard-to-reach marginalized HIV-infected individuals. As part of a multisite initiative evaluating outreach programs that target underserved HIV-infected individuals, 610 participants were interviewed about their HIV disease, health services utilization, substance use, mental health, and case management. Primary outcomes included ambulatory, emergency department, and inpatient visits. Generalized estimating equations were used in logistic regression analyses. On regression analyses ambulatory visits were associated with having insurance (adjusted odds ratio [AOR] = 2.46), mental health medications (AOR = 7.46), and case management (AOR = 4.81). Emergency department visits were associated with having insurance (AOR = 1.74), homelessness (AOR = 2.23), poor health status (AOR = 2.02), length of HIV infection (AOR = 2.02), mental health care (AOR = 1.47), mental health medications (AOR = 1.59), and heavy alcohol intake (AOR = 1.46). Hospitalizations were associated with high school education (AOR = 1.57), having insurance (AOR = 10.45), homelessness (AOR = 2.18), poor health status (AOR = 2.64), length of HIV infection (AOR = 2.03), and mental health medications (AOR = 1.87). In hard-to-reach marginalized HIV-infected individuals, having insurance, case management and mental health care were associated with increased ambulatory visits. These findings support HIV multidisciplinary care with marginalized populations. Understanding factors associated with health care utilization is essential for outreach programs to facilitate engagement in HIV care.
