Objectives To study the effect of caregiver‐focused interventions to support medication safety in older adults with chronic disease.
Design Systematic review.
Setting Studies published before January 31, 2017, searched using Ovid Medline, PubMed, EMBASE, Scopus, CINAHL, PsycINFO, and Google Scholar.
Participants Caregivers with or without a care recipient.
Measurements Inclusion criteria: interventions focused on caregivers aiming to improve medication safety. Studies not focusing on older adults, not evaluating medication safety, failing to include caregivers, or without a comparison group were excluded.
Results The initial search revealed 1,311 titles. Eight studies met inclusion criteria. The strategies used in randomized trials were a home‐based medication review and adherence assessment by a clinical pharmacist (2 home visits 6–8 weeks apart, with pharmacist and physician meeting independently) that found no difference in nonelective hospital admissions (p=.8) but fewer medications (p=.03); a 19‐minute educational DVD and an hour‐long medication education and training that improved caregiver satisfaction (p<.04); a medication education and adherence intervention (2–3 home visits per care recipient and caregiver dyad over 8 weeks) that found no difference in knowledge, administration, or accessibility of medications (p=.29); and a collaborative case management program (16‐month program of assessment, meeting, and monthly follow‐up telephone calls) that reduced perceived caregiver burden (p=.03). Quasi‐experimental trials included collaborative care transitional coaches, an outpatient collaborative care model, and education and training programs. Of these, educational interventions showed improvements in self‐efficacy, confidence, and preparedness. The collaborative care intervention reduced rehospitalizations (p=.04) and improved quality‐of‐care outcomes.
Conclusion Although some interventions improved caregiver medication knowledge and self‐efficacy, effects on clinical outcomes and healthcare use were insufficiently studied. Two studies implementing collaborative care models with medication management components showed potential for improvement in quality of clinical care and reductions in healthcare visits and warrant further study with respect to medication safety.
