System and patient barriers to appropriate HIV care for disadvantaged populations: the HIV medical care provider perspective

A Social Network Analysis of Cooperation and Support in an HIV Service Delivery Network for Young Latino MSM in Miami

Purpose: The study aimed to identify HIV prevention, testing, and care services prioritizing young Latino men who have sex with men (MSM) in an HIV service delivery network in Miami-Dade County, Florida, by visually describing structural features and processes of collaboration within and between health and social venues.Methods: The study used cross-sectional data from 40 social and healthcare venues providing goods and services to young Latino MSM. Each venue provided information surrounding HIV-related services provided and collaborations with other venues. Network visualization analyses were performed using UCINET6 and NetDraw2.160.Results: The most commonly used services offered by health and social venues were free condoms and HIV education materials. Collaborations both within and between health and social venues components of the network existed. Not all health and social venues provided services to young Latino MSM.Conclusion: Health venues can reach and incorporate hard to reach populations, such as non-English speaking and undocumented young Latino MSM, to provide HIV-related services using service delivery venue social networks.

Providers caring for adolescents with perinatally-acquired HIV: Current practices and barriers to communication about sexual and reproductive health

The population of adolescents and young adults (AYA) with perinatally-acquired HIV (PHIV) present challenges to HIV healthcare providers (HHCPs). Originally not expected to survive childhood, they are now living well into young adulthood. Little is known about the type of sexual and reproductive (SRH) information/services offered to AYA with PHIV by HHCPs. HHCPs (n=67) were recruited using snowball sampling, and completed an online survey. Providers' most frequently endorsed SRH topics discussed with both male and female patients included condom use (77.3%), STD prevention (73.1%), and screening (62.1%). Providers' reports indicated that females received significantly more education about SRH topics overall. The most frequently noted barriers to SRH communication included more pressing health concerns (53.0%), parent/guardian not receptive (43.9%), and lack of time during appointment (43.9%). Provider-reported SRH conversations with HHCPs were highly focused on horizontal transmission and pregnancy prevention. Salient social aspects of SRH promotion for AYAs with PHIV (e.g., managing disclosure and romantic relationships) were less commonly discussed, though such conversations may serve to reduce secondary transmission and enhance the overall well-being of AYA with PHIV. Findings indicated that further work must be done to identify strategies to address unmet SRH needs of the aging population of AYA with PHIV.

System and Patient Barriers to Care among People Living with HIV/AIDS in Houston/Harris County, Texas: HIV Medical Care Providers' Perspectives

In the United States, a considerable number of people diagnosed with HIV are not receiving HIV medical care due to some barriers. Using data from the Medical Monitoring Project survey of HIV medical care providers in Houston/Harris County, Texas, we assessed the HIV medical care providers' perspectives of the system and patient barriers to HIV care experienced by people living with HIV/AIDS (PLWHA). The study findings indicate that of the 14 HIV care barriers identified, only 1 system barrier and 7 patient barriers were considered of significant (P ≤ .05) importance, with the proportion of HIV medical care providers' agreement to these barriers ranging from 73.9% (cost of health care) to 100% (lack of social support systems and drug abuse problems). Providers' perception of important system and patient barriers varied significantly (P ≤ .05) by profession, race/ethnicity, and years of experience in HIV care. To improve access to and for consistent engagement in HIV care, effective intervention programs are needed to address the barriers identified especially in the context of the new health care delivery system.

Site migration in seeking care services from multiple providers is associated with worse clinical outcomes among HIV-infected individuals in Washington, DC

Washington, DC, is a metropolitan city with a severe HIV epidemic and faces challenges in retaining people living with HIV (PLWH) in quality care. This study assessed site migration in seeking care services and its correlates among PLWH in DC. PLWH diagnosed before 2008 and living through the end of 2010 were analyzed. Six scenarios of site migration were examined as patients visited =2, =3, and =4 different providers for their CD4 cell count and/or viral load (VL) tests in the past 3 years from 2008 to 2010 and 2 years from 2009 to 2010, respectively. Of 6480 patients analyzed from 2008 to 2010, 18.4% had CD4 < 200 cells/mm(3), 30.5% had VL > 400 copies/mL, and 76.6% were retained in same care sites; 23.4%, 5.0%, and 0.9% visited =2, =3, and =4 sites in the past 3 years from 2008 to 2010, respectively. Of 5954 patients analyzed from 2009 to 2010, 16.8% had CD4 < 200 cells/mm(3), 29.4% had VL > 400 copies/mL, and 81.9% were retained in same care sites; 18.1%, 3.1%, and 0.6% visited =2, =3, and =4 sites in the past 2 years from 2009 to 2010, respectively. Multivariable logistic regression analyses revealed that migration across six scenarios are consistently associated with CD4 < 200 cells/mm(3) and VL > 400 copies/mL. Site migration was common and associated with lower CD4 and higher VL among PLWH in DC. Frequent migration might be a factor in achieving optimal health outcomes for a subset of patients. Site migration might potentially limit effective delivery of high quality care and treatment services. The preliminary findings underscore the need for further research to assess the predictors of migration and its impact on stage of care.

Identifying gaps in HIV prevention services

Human immunodeficiency virus (HIV) prevention programs and agencies are fighting growing rates of infection with decreasing resources. Identification of gaps in HIV prevention services can help inform prevention funding and program policies. To describe HIV prevention needs in a southern U.S. state, we conducted face-to-face interviews with prevention agencies and persons considered by others in their community to be "influential informants" of the community's HIV prevention services in a sample of counties in North Carolina. Using county as the unit of analysis (n = 10), we investigated differences in gaps by community characteristics, such as disparities in sexually transmitted disease rates. Lack of programs and problems with service program coordination/cooperation were reported frequently by rural counties. The most commonly reported barrier to meeting the needs of persons at risk for HIV was funding, followed by stigma. Findings from this study can inform local and regional planners on how to efficiently target prevention programs, including programs aimed at reducing racial and geographic disparities in sexually transmitted diseases, such as HIV.

Current issues in care and support for HIV-positive gay men in Sydney

We explored current access to care among HIV-positive people in Australia. In 2006, 270 HIV-positive gay men from a community-based Positive Health cohort in Sydney were asked about their health (including medical and social) service needs and, subsequently, about difficulty in accessing services. We report the prevalence of specific needs, barriers and associated factors. Participants most commonly used general practitioners (64%) for HIV management and needed at least one HIV-related medical service (usually several: doctors experienced in HIV management, dentists and hospital pharmacies). Most participants were able to access them. Barriers in accessing services were related to their convenience rather than lack or quality. Cost emerged as a substantial barrier to dental care and psychological counselling (91% and 48% respectively of those in need). Need for an HIV-related social service was reported by 46% of respondents. Difficulties in accessing these related to poor services and staff attitudes. Income was associated with limited access to multiple services. In Australia, HIV-related medical service needs outweigh those for social services. Complex health services remain essential to HIV-positive people, but some services are currently not meeting their needs. To remain adequate, services need to understand and constantly adapt to the changing needs of HIV-positive people.

Appropriateness of antiretroviral therapy in clients of an HIV/AIDS case management organization

We sought to assess appropriateness of antiretroviral therapy (ART) reported by clients of an HIV/AIDS case management organization and identify variables associated with appropriate ART receipt. A total of 295 such clients were mailed a survey asking them to identify antiretroviral medications they were taking. Of them 220 (75%) returned surveys; 201 (93%) were taking antiretrovirals. Of these, 159 were on appropriate and 36 on inappropriate ART, as determined by guidelines created by the CDC, the International AIDS Society (USA Panel), and the Panel on Clinical Practices for Treatment of HIV Infection. In unadjusted analyses, age, sex, race, sexual orientation, history of injection drug use, history of sexual risk, and HIV knowledge were associated (p< or =0.10) with appropriate ART and entered into one of two logistic regression models. The first model indicated that women (p=0.003) and heterosexuals (p=0.001) were less likely to receive appropriate ART than men and gay/bisexuals (and variables interacted, p=0.001). HIV knowledge--a proxy indicator determined by self-report of a CD4 cell count and viral load--was added to variables retained in first model to create a second model. Only sexual orientation was retained in this second model (p=0.02, in the same direction as in the first model), and those with less versus more HIV knowledge (p=0.04) were found to be less likely to receive appropriate ART (and variables interacted, p=0.04). Findings suggest that heterosexual men are less likely than women who, in turn, are less likely than gay/bisexual men to receive appropriate ART. HIV-related knowledge appears to increase likelihood of receiving appropriate ART and it attenuates the effect of sex.
