Community Home-based Care Intervention and Its Health Outcome in HIV-positive People

HIV continues to be a global health problem, particularly mental health status and non-adherence to ART remains challenges in people living with HIV (PLHIV) in low- and middle-income countries. Mental health disorders, particularly those who experience depression and anxiety may endure poor satisfaction or trust to the treatment, leading to non-adherence to ART. Also, those, who have high level of perceived stress may not seek adequate social support from care givers and service providers, that may worsen their ART adherence. Substance use also induces poor coping skills and poor dependence on treatment. HIV positive people also experience co-occurring mental health disorders and substance use. For instance, those who experienced depression are more likely to develop the risk of substance use compared to those who did not experience depression. Similarly, those who engage in substance use such as amphetamine, cocaine, and opioid may develop the risk of chronic stress. However, evidence is limited about the prevalence of co-occurring pattern of these conditions on ART adherence among them worldwide. Psychosocial support may be an integral part of HIV care and support to meet the mental health needs of people living with HIV. To address the need for psychosocial support, WHO provided the guideline to manage their psychological and social problems. The guideline recommends that HIV-positive people, their families, and caregivers receive psychosocial support at family, community, and health facility level. It also suggests that psychosocial support should be an integral part of care and support framework for HIV services. Community and home-based care program is designed as a WHO framework for providing psychosocial support and basic health care to PLHIV. According to this framework, it is defined as any form of care given to ill people in their homes. Such care includes physical, psychosocial, palliative, and spiritual activities. The goal of this program is to provide hope through high-quality and appropriate care that helps ill people and families to maintain their independence and achieve the best possible QOL. The program may incur low cost or can be sustainable strategy for providing comprehensive services at the home of PLHIV. In Nepal, 23 non-governmental organizations (NGOs) provide care and support services through community home-based care program in Nepal. The program comprises psychosocial support, ART adherence and support, peer counseling, basic health care, referral for further care. However, little is known about the role of community home-based care program in reducing depression, anxiety and high stress level among people living with HIV in the country. In addition, they receive peer counseling about their substance use, however, no study examined the role of such intervention to reduce substance use. Also, the program comprises ART support and counseling to HIV positive people and their family, no study has examined its effect on non-adherence to ART. This study is aimed to assess the impact of community home based care program on depressive symptoms, anxiety, high stress, and substance use and non-adherence to ART. A intervention study was conducted among 682 PLHIV in Nepal. Among them, 344 participants were assigned for community and home-based care intervention and 338 were assigned for control. Baseline information was collected including sociodemographic characteristics, HIV/AIDS clinical staging, depressive symptoms, anxiety, and stress scores, substance use. Depressive symptoms were measured using center for epidemiological study depression scale (CESD). Anxiety was measured with composite international diagnostic interview-short form (CIDI-SF). Perceived Stress Scale measured stress scores. ART non-adherence was measured if participants missed at least two pills in past months. After six months, a follow up survey was done and collected the information as baseline. The analysis was done with mainly three strategies. First, the associations of independent and combined mental health disorders and substance use with non-adherence to ART were examined using logistic regressions stratified by gender. Separate models for generalized estimating equation (GEE) were applied to measure the effect of community home-based care intervention on various outcomes. Two models for GEE were developed. First, the effect of community home-based care intervention on depression, anxiety, high stress and substance use were assessed. Second GEE model examined the effect of intervention on non-adherence to ART. In all GEE multivariable models, age, gender, marital status, education, employment, HIV/AIDS clinical staging, and presence of physical symptoms were controlled.
