Editorial: Evidence on the benefits of integrating mental health and HIV into packages of essential services and care

Résumé

People living with HIV (PLWH) suffer disproportionately higher levels of mental disorders than the general population, both in high-income and low-and middle-income countries (1). There is also evidence to suggest that the burden of mental disorders is worse `in HIV compared to other chronic diseases (2). Mental disorders negatively affect client engagement and care retention and result in significant distortions in health outcomes at every stage of the HIV care continuum (1). The need for mental health care for PLWH is critical to mitigate HIV transmission and progression and improve clinical outcomes by creating awareness for mental disorders and integrating mental health services into the HIV care continuum. The Joint United Nations Programme on HIV/AIDS (UNAIDS) and World Health Organization (WHO) have underscored the importance of integrating HIV and mental health services, considering that both conditions accentuate each other's risk. Also, Integrated HIV-mental health approaches lead to better health outcomes, overall well-being and quality of life (3). More so, the "feasibility and acceptability of integrating mental health screening into an existing community-based program for prevention of mother-to-child transmission of HIV targeted at pregnant women and their male partners" is acceptable (4). For success, service integration should conform with all the critical elements of integrated service delivery as outlined by the WHO-"the management and delivery of health care services so that the clients receive a continuum of preventive and curative services that cater to their needs over time and across different levels of the health system" (5). This editorial highlights some of the benefits of HIV-mental health services integration by introducing nine manuscripts published as a collection in response to the Research Topic: Evidence on the Benefits of Integrating Mental Health and HIV into Packages of Essential Services and Care. The manuscripts are from both high-income and low-and middle-income countries. Specifically, three are from China, two from the United States of America and one each from Ethiopia, Guinea, Kenya and Nigeria. The manuscripts 1) underscore the high prevalence of mental disorders among people living with HIV, 2) demonstrate that mental disorders lead to suboptimal health outcomes among PLWH, and 3) demonstrate the value of integrating mental health care into HIV care programs (Table 1).HIV infection is disproportionately associated with mental disorders PLWH experience disproportionately high levels of many common mental disorders. Depression is significantly associated with HIV infection in studies from Nigeria, the US and China Although it has been demonstrated that mental disorders are commoner among PLWH than the general population, it is unlikely that all HIV subpopulations are equally vulnerable to mental disorders. This collection shows that men, homosexuals, unmarried and the depressed are more affected by suicidal ideations. Also, longer periods since HIV diagnosis and lower CD4 cell counts were associated with a higher risk of suicidal ideation (Li et al.). Other factors that are related to mental disorders in PLWH include being female, serodiscordant partners, low-income levels, lack of family support, duration on ART and the gestational age among HIV-positive pregnant women (Akinsolu et al.).Mental disorders are associated with HIV progression, poor medication adherence and exacerbation of the social and economic barriers to accessing HIV care, resulting in poor health outcomes and suboptimal quality of life (8). In this collection, Qian et al. used a Structural Equation Model to demonstrate a link between loneliness and reduction in health-related quality of life. Suicidal ideation is also associated with lower CD4 counts (Li et al.), while low self-efficacy is also related to drug side effects (Aldisa et al.). More so, the social context and stigmatising social process in which PLWH live, causes them to be stigmatised which further affects HIVrelated health outcomes (9).Integrating mental health services into HIV care programs has the potential to mitigate the risk of disease progression and engender better health outcomes. Integrated service delivery also increases health system efficiency and patient satisfaction. Although available evidence demonstrates the value of service integration, health system challenges, including human resources, infrastructure and supply chain management, often constitute significant hindrances. Critical success factors include human capital development, awareness creation, stakeholder ownership and commitment and continuous health system development (5). This collection also demonstrates the benefit (real or potential) of implementing mental health care interventions within HIV care programs. Integration of psychosocial counselling into HIV care promotes confidentiality, provider availability and care, improved access to antiretrovirals and patient preferences. These factors in turn optimize patient-centred care and result in better health outcomes for people living with HIV (Kolie et al.). Also, building the capacity of HIV caregivers will increase the enhance the diagnosis and referral of mental disorders. Concepcion et al. piloted a three-day Simulated Patient Encounter training on HIV care providers in Kenya. The study shows that evidence-based provider training can improve their competencies and service delivery for common mental disorders in HIV care settings. Anderson et al. underlined the significance of implementing trauma-informed care and trauma-responsive services in HIV settings to avoid re-traumatization in those with experience of intimate partner violence. The study also demonstrates that the success of HIV-mental health integration strategies hinges on the appropriate characterization of health facilities based on critical success factors depending on the core issue under consideration.In summary, mental disorders disproportionately affect PLWH and result in poor HIV and mental health outcomes. Integrating mental health and HIV into Packages of Essential Services and Care will help recognize and address mental health needs and result in better health outcomes among PLWH.
