Review Meta Analysis
The Effects of Feedback on Adherence to Treatment: A Systematic Review and Meta-analysis of RCTs.
The aim of this systematic review is to determine whether providing feedback, guided by subjective or objective measures of adherence, improves adherence to treatment. ⋯ Feedback guided by objective or subjective measures of adherence improves adherence and, perhaps more importantly, prevents worsening of adherence over time even when only small absolute improvements in adherence were noted. Increased use of feedback to improve treatment adherence has the potential to reduce avoidable healthcare costs caused by non-adherence.
