HPCSA Surgery Registrar Research Requirements

All HPCSA general surgery registrars must complete a research project during their 5-6 year training programme. The research protocol must be submitted within the first 18-24 months of registrar training, approved by a supervisor, cleared by IRB before data collection, and clinically relevant to South African surgical practice.

Given South Africa’s unique surgical disease burden – including high trauma volumes, late-presenting cancers, HIV-related surgical conditions, and resource constraints – surgery research topics should address these realities while maintaining methodological rigor and feasibility within public sector surgical units.
