Necessity and concerns beliefs and HIV medication adherence: a systematic review

According to the Necessity-Concerns Framework, beliefs about medication necessity and concerns are two core themes from diverse patient medication beliefs across chronic illnesses that may directly influence adherence. Past work has supported associations of necessity and concerns to adherence in the chronic disease literature and in HIV research. However, there has not been a focused review of the literature on associations of necessity and concerns to HIV medication adherence, nor on what variables may influence these associations. This systematic review synthesized findings from 26 studies regarding associations of necessity and concerns to HIV medication adherence. Both beliefs showed small, clinically significant effects on adherence. A subset of studies identified perceptions of healthcare providers as determinants of necessity and concerns beliefs with indirect effects on adherence. Overall, necessity and concerns demonstrated clinically significant associations to adherence among people with HIV.
