Coronavirus Infection in Hip Fractures (CHIP) Study A Case Matched Multi-Centre Study of 1633 Hip Fracture Patient

Description

In this presentation, Fatima Rashid discusses the findings of the CHIP study, which examined the impact of COVID-19 on hip fracture patients during the pandemic. The study was a case-matched multicenter analysis involving 1,633 patients, initiated at the pandemic's onset in March 2020 and published in the Bone and Joint Journal. Rashid highlights that despite the lockdown, the incidence of hip fractures remained constant, and the 30-day mortality for COVID-positive patients soared to 35.6%, compared to 7.7% for COVID-negative patients. The research aimed to investigate not only mortality rates but also factors such as time to surgery and vitamin D levels. The study concluded that COVID-19 was a significant independent risk factor for increased mortality, underscoring the importance of vitamin D in patient outcomes, while also noting that subsequent studies (CHIP 2 and CHIP 3) did not find the anticipated connections. Rashid answered audience questions about matching controls and the limitations of causation in observed associations.
