Abstract
Introduction Around 75 000 people suffer from hip fractures yearly in the United Kingdom (UK) leading to significant mortality and morbidity. Although mortality has dropped from 8% to 5% between 2013 and 2023 after hip fractures, those undergoing surgery for hip fractures have a 30-day readmission rate which has remained stagnant at around 11% over the same decade in the UK. This study protocol describes a mixed-methods investigation (The ARTHUR Study—avoiding readmission after hip fracture) which aims to understand and offer solutions to prevent avoidable 30-day readmission after hip fracture surgery. The study will focus on two hospitals in acute and community settings in a large urban and ethnically diverse city in the UK. Methods and analysis We describe two work packages. Work Package One (WP1) involves analysis of 5 year’s worth of routinely collected health data provided by PIONEER, a Health Data Research UK data hub in Acute Care for our local population. Work Package Two (WP2) will involve semistructured interviews with patients, carers or family members as well as non-participant observations of hospital processes to understand systems-based issues related to readmissions after hip fracture surgery. Although recruitment may be an issue, our timeline for recruitment reflects this. We also aim to recruit a diverse population, which has often been under-represented in studies into hip fractures and aim to explore relevant interventions which can be widely generalisable. Ethics and dissemination This protocol was submitted via IRAS: 330074 and obtained UK NHS REC approval via the West Midlands Coventry and Warwickshire Research Ethics Committee (REC 23/WM/0242) on 25 January 2024. The results of this study will be published in relevant scientific journals and presented at orthopaedic, fragility fracture and geriatric specialty conferences and scientific meetings. A lay summary of the findings will be publicly available on the HRA website.
