Barriers and Solutions to Successful Problem- Based Learning Delivery in Developing Countries - A Literature Review

Problem-based learning (PBL) was introduced in the 1960s as an alternative to traditional teacher-centered and discipline-based preclinical medical education. A literature review was conducted to explore the barriers and solutions to successful PBL uptake and delivery in developing countries. The review involved the search of articles and scientific studies on PubMed, The Lancet, and Scielo. The review focused on the medical education literature, using as a primary search criterion "problem-based learning" in combination with "developing countries" and "education". The search was limited to articles in Spanish and English published between 2011 and November 2021, except for three articles due to their relevance to the subject. Faculty development programs are the cornerstone when implementing a new methodology in developing countries. Early career development, PBL methodology, and the available assessment options should be the primary learning objectives of these programs. Stakeholders will need to plan using available resources following the experience of other countries and institutions encouraging collaborative development. Evaluation and assessment will be crucial to understand the impact of PBL, and considerations should be taken to implement an integrated curriculum. Medical Education Research should be encouraged, appraised, and disseminated to improve evidence-based decision-making, creating a constant development cycle. PBL is innovative and represents many unanswered questions that will develop in the following decade as more schools implement new methodologies and Research on PBL.
