HPCSA Internal Medicine Registrar Research Requirements

All HPCSA internal medicine registrars must complete a research project during their 4-year training programme. The research protocol must be submitted within the first 12-18 months of registrar training, approved by a supervisor, cleared by IRB before data collection, and clinically relevant to South African internal medicine practice.

Given South Africa’s unique disease burden – including the world’s largest HIV epidemic, high TB prevalence, and rising non-communicable diseases – internal medicine research topics should address these realities while maintaining methodological rigor and feasibility within resource-constrained settings.
