Patient Adherence to Follow-Up in Clinical Research: A Systematic Review of Measurements, Associated Factors and Intervention Strategies

Objectives: A patient's adherence to follow-up (AFU) plays a key role in the implementation of clinical research with respect to cost and validity. Most present studies focus exclusively on some specific steps during clinical research implementation, regardless of the synthetic action of patientsociety-medicine system. The objective of the study is to provide a comprehensive systematic review of the measurements, associated factors and intervention strategies of AFU across a broad spectrum.
