Barriers and Facilitators to Implementing Interventions for Improving Medication Adherence in Older Patients With Hypertension: A Scoping Review.

AIMS: To identify the barriers and facilitators to implementing interventions for improving medication adherence in older patients with hypertension.

DESIGN

This review was designed according to the Arksey and O'Malley framework for scoping reviews.

DATA SOURCES: Six electronic databases (PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and PsycINFO) were searched.

REVIEW

METHODS

This review is written in a consistent format in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

RESULTS

Fifteen studies were included in the final analysis. Barriers and facilitators were mapped to 14 constructs across the four CFIR domains. Barriers mapped to 'intervention characteristics' spanned multiple constructs, more than any other domain. Similarly, the most frequently mentioned facilitators were derived from the 'intervention characteristics' domain. Overall, the intervention content of the existing studies was not generalisable and accessible, whereas other factors such as family involvement in the 'process' were effective in facilitating interventions implementation.

CONCLUSIONS

This review identified barriers and facilitators to the implementation of interventions to improve medication adherence in older patients with hypertension. Future research should focus on reducing barriers and reinforcing facilitating factors to ensure improved medication adherence in the older population with hypertension.

IMPACT: This review provides a systematic overview of the barriers and facilitators to the implementation of interventions for improving medication adherence in older patients with hypertension. Whether as a barrier or a facilitator, the 'intervention characteristics' are predominant. This review will provide guidance for improving medication adherence in older patients with hypertension.
