Improving Referrals for HIV Care Through Organizational Network Analysis.

CONTEXT: The link between testing for HIV and obtaining antiretroviral therapy (ART) is central to the HIV/AIDS control strategies of UNAIDS (the "90-90-90" goals) and the International Association of Providers of AIDS Care ("Test and Start"). To ensure that 90% of those diagnosed with HIV/AIDS begin ART and 90% of those on ART achieve viral suppression, service providers not providing all services need to refer patients to other organizations. SETTING: Homa Bay, Kenya. OBJECTIVE: Homa Bay county's HIV/AIDS prevalence is one of the country's highest. We identified the organizations providing some aspect of HIV/AIDS care and investigated ways in which they work together, or do not, to cover the comprehensive needs of those they serve. DESIGN AND PARTICIPANTS: We identified 56 organizations and interviewed a representative from each about his or her organization's services and its connections with the other 55, with particular interest in referrals from sites that test for HIV but do not treat infections to sites that do treat infections. MAIN OUTCOME MEASURE: Referral connections. RESULTS: Referral connections among the 56 in the past 30 days were relatively rare, averaging fewer than 2; 13 organizations made no referrals at all. Notably, 5 facilities that test for HIV did not refer their clients to an ART provider. We found 2 distinct clusters of connected organizations: one in Homa Bay Township and the other in Rangwe subcounty. When we convened the organizations and presented our results to them, they expressed interest in establishing better connections and referrals. CONCLUSIONS: Homa Bay has an opportunity to improve care for people with HIV/AIDS, in particular ensuring that those testing positive receive treatment, simply by making better use of the services already available. This can be achieved by informing each organization of the services provided by each of the others and by bringing the organizations together to plan and monitor the services' coordination. These steps could be implemented separately in each of the 2 organizational clusters.

Trauma history and depression predict incomplete adherence to antiretroviral therapies in a low income country.

BACKGROUND: As antiretroviral therapy (ART) for HIV becomes increasingly available in low and middle income countries (LMICs), understanding reasons for lack of adherence is critical to stemming the tide of infections and improving health. Understanding the effect of psychosocial experiences and mental health symptomatology on ART adherence can help maximize the benefit of expanded ART programs by indicating types of services, which could be offered in combination with HIV care. METHODOLOGY: The Coping with HIV/AIDS in Tanzania (CHAT) study is a longitudinal cohort study in the Kilimanjaro Region that included randomly selected HIV-infected (HIV+) participants from two local hospital-based HIV clinics and four free-standing voluntary HIV counselling and testing sites. Baseline data were collected in 2008 and 2009; this paper used data from 36 month follow-up interviews (N = 468). Regression analyses were used to predict factors associated with incomplete self-reported adherence to ART. RESULTS: Incomplete art adherence was significantly more likely to be reported amongst participants who experienced a greater number of childhood traumatic events: sexual abuse prior to puberty and the death in childhood of an immediate family member not from suicide or homicide were significantly more likely in the non-adherent group and other negative childhood events trended toward being more likely. Those with incomplete adherence had higher depressive symptom severity and post-traumatic stress disorder (PTSD). In multivariable analyses, childhood trauma, depression, and financial sacrifice remained associated with incomplete adherence. DISCUSSION: This is the first study to examine the effect of childhood trauma, depression and PTSD on HIV medication adherence in a low income country facing a significant burden of HIV. Allocating spending on HIV/AIDS toward integrating mental health services with HIV care is essential to the creation of systems that enhance medication adherence and maximize the potential of expanded antiretroviral access to improve health and reduce new infections.

Prevalence of psychological trauma and association with current health and functioning in a sample of HIV-infected and HIV-uninfected Tanzanian adults.

BACKGROUND: In high income nations, traumatic life experiences such as childhood sexual abuse are much more common in people living with HIV/AIDS (PLWHA) than the general population, and trauma is associated with worse current health and functioning. Virtually no data exist on the prevalence or consequences of trauma for PLWHA in low income nations. METHODOLOGY/PRINCIPAL FINDINGS: We recruited four cohorts of Tanzanian patients in established medical care for HIV infection (n = 228), individuals newly testing positive for HIV (n = 267), individuals testing negative for HIV at the same sites (n = 182), and a random sample of community-dwelling adults (n = 249). We assessed lifetime prevalence of traumatic experiences, recent stressful life events, and current mental health and health-related physical functioning. Those with established HIV infection reported a greater number of childhood and lifetime traumatic experiences (2.1 and 3.0 respectively) than the community cohort (1.8 and 2.3). Those with established HIV infection reported greater post-traumatic stress disorder (PTSD) symptomatology and worse current health-related physical functioning. Each additional lifetime traumatic experience was associated with increased PTSD symptomatology and worse functioning. CONCLUSIONS/SIGNIFICANCE: This study is the first to our knowledge in an HIV population from a low income nation to report the prevalence of a range of potentially traumatic life experiences compared to a matched community sample and to show that trauma history is associated with poorer health-related physical functioning. Our findings underscore the importance of considering psychosocial characteristics when planning to meet the health needs of PLWHA in low income countries.
