A Systematic Review of Patient Education Strategies for Oncology Patients in Low- and Middle-Income Countries

INTRODUCTION: Patient education can facilitate early cancer diagnosis, enhance treatment adherence, and improve outcomes. While there is increasing cancer burden in low- and middle-income countries (LMICs), there is little research to inform successful patient education in these regions. This systematic review summarizes the existing literature on oncology education and evaluation strategies in LMICs, identifies best practices, and highlights areas which require further investigation. METHODS: The review was conducted using PRISMA guidelines and an a priori protocol. Four databases (Ovid Medline, Cochrane Libraries, Embase, and Cabi) were searched in December 2021. Two independent reviewers evaluated studies for inclusion. Using a coded data extraction form, information was collected about the study site, intervention characteristics, and evaluation methods. RESULTS: Of the 2047 articles generated in the search, 77 met the inclusion criteria. Twenty-four countries were represented; only 6 studies (8%) were in low-income countries. The most common education methods included technology-based interventions (31, 40%) and visual pamphlets or posters (20, 26%). More than one education method was used in 57 (74%) studies. Nurses were the most frequent educators (25, 33%). An evaluation was included in 74 (96%) studies, though only 41 (55%) studies used a validated tool. Patient knowledge was the most common measured outcome in 35 (47%) studies. CONCLUSIONS: There is limited empiric research on oncology patient education in LMICs. The available data show heterogeneity in education approaches and gaps in evaluation. Further research to determine successful patient education and evaluation strategies is urgently needed to improve treatment cancer outcomes in LMICs.
