HPCSA Anaesthetics Registrar Research Requirements

All HPCSA anaesthetics 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 anaesthesia and critical care practice.

Given South Africa’s unique perioperative challenges – including high HIV prevalence affecting anaesthetic complications, resource-limited ICU settings, maternal mortality concerns in obstetric anaesthesia, and trauma burden – anaesthetics research topics should address these realities while maintaining methodological rigor and feasibility.
