Abstract
This systematic review examines the outcome of integrated care intervention on the treatment of chronic illness, specifically, HIV/AIDS and cancer. Twenty-three studies conducted between 2000 and 2015 were included for final review, assessed for quality, and thematically analyzed and organized by outcome measure. Studies reporting on survival rates for cancer patients did not report significant improvement for those receiving integrated psychological or psychosocial intervention, with the exception of a single study. More favorable outcomes were reported for integrated care interventions aimed at increasing quality of life and psychosocial wellbeing. Medical outcomes for HIV/AIDS patients were more promising, particularly in regard to immune system function and medication adherence. Psychosocial and behavioral outcomes for persons living with HIV/AIDS were less favorable, although these studies were least represented within the sample. Fifteen of the studies included for review reported significant outcomes for their primary measures as the result of integrated care interventions. Limitations are discussed and future research directions are suggested.
