Phone Calls to Retain Research Participants and Determinants of Reachability in an African Setting: Observational Study.

ABSTRACT:

Background

Long-term retention of research participants in studies is challenging. In research in sub-Saharan Africa, phone calls are the most frequently used method to distantly engage with participants.

Objective

We aimed to get insight into the effectiveness of phone calls to retain contact with participants and evaluated determinants of reachability.

Methods

A cross-sectional study was performed using the databases of two randomized controlled trials investigating different kinds of antiretroviral therapy in HIV-positive patients. One trial finished in 2018 (study 1), and the other finished in 2015 (study 2). A random sample size of 200 participants per study was obtained. There were up to 3 phone numbers available per participant collected during the studies. Par
