Literature on integrated HIV care: a review

Abstract

With a significant proportion of HIV-infected patients now presenting with co-occurring substance abuse disorders and mental disorders, interest in integrated HIV care is growing. However, no review of integrated HIV care has been conducted. Using relevant key word searches of the Medline and Psychlit databases, the authors identified about 450 publications. The few evaluations of integrated models tended to focus on measurements of engagement and retention in medical care, and their findings indicated an association between integrated HIV care and increased service utilization. No random assignment controlled studies were identified, except in the peripheral area of integrated care (without HIV primary care) for persons with co-occurring substance abuse disorders and mental disorders. The majority of reviewed articles described integrated models operating in the field and various aspects of implementation and sustainability. Overall, they supported use of a wide range of primary and ancillary services delivered by a multidisciplinary team that employs a ‘biopsychosocial’ approach. Despite the lack of scientific knowledge regarding the effects of integrated HIV care, those wanting to optimize treatment for patients with multiple interacting disorders can gain useful and practical knowledge from this literature.
