Mapping How the World Really Does Hip Replacement

Send us Fan Mail How does hip replacement practice really differ from one country to the next? Researcher Irrum Afzal joins the AHF Podcast to discuss the Global Arthroplasty Practice Survey (GAPS) — the first effort to map how surgeons worldwide actually perform total hip replacement. Despite roughly seventy years of modern hip replacement, there's still no global consensus on the fundamentals — surgical approach, fixation, bearing surface, or the perioperative pathway. National joint registries capture some of this, but their coverage and data quality vary widely, and many countries have no registry at all. The result is that we know surprisingly little about how the operation is actually performed around the world. Irrum Afzal, a researcher at Imperial College London and a digital health transformation specialist, is working to close that gap. Co-led with Professor Richard Field, GAPS asks surgeons of every volume and career stage to describe their real preoperative, intraoperative, and postoperative practice. It takes under ten minutes, covers the full patient journey, and is built to feed a long-term dataset that machine learning can eventually turn into research priorities and a working global consensus. Along the way, Irrum explains how her study on the accuracy of National Joint Registry revision data shaped her thinking about data quality, why anterior approach adoption ranges from around 1% in the UK to 56% in the US, and what surgeon-reported practice data can add to what registries already collect. If you perform hip replacement, your answers help build the first real worldwide picture of the field — and the survey is open through 30 June.
