Title : Benchmarking early unplanned trauma re-operations: A five-year institutional review of 7,400 orthopaedic cases
Abstract:
Early unplanned re-operations following trauma surgery are widely recognized as key indicators of surgical quality, postoperative complications, and institutional performance. This five-year retrospective review analyzed 7,486 orthopaedic trauma operations performed at Luton and Dunstable University Hospital between January 2019 and June 2024 to benchmark the incidence, causes, and timing of early unplanned returns to theatre. A total of 53 cases (0.71%) required re-operation within 28 days, aligning with national UK benchmarks such as the NHFD’s reported ~1% 30 day re-operation rate.
Infection was the leading cause of re-operation, accounting for 40% of cases, followed by implant/fixation failure (26%) and prosthetic dislocation (19%). As stated in the paper, infection was the commonest indication at 40% followed by implant/fixation failure at 26% and dislocation at 19%. These complications disproportionately affected older patients, with dislocation cases demonstrating the highest mean age (81.4 years). ASA grade differed significantly across indication groups, with infection and dislocation occurring in physiologically higher-risk patients.
Hip and femur procedures represented 43% of all re-operations and were significantly associated with older age groups. Most re-operations occurred during postoperative weeks 2–3 (72%), highlighting a critical surveillance window for early detection of complications. Microbiological analysis revealed culture positivity in 57% of infection related cases, predominantly Staphylococcus aureus, and 33.3% of these patients experienced long-term complications or mortality within 24 months. As noted in the article, 33.3% of the infection-related re-operated cases resulted in long-term complications or mortality within 24 months.
The findings reinforce the importance of targeted quality improvement initiatives, including enhanced infection control pathways, improved fixation strategies for osteoporotic bone, and optimized postoperative monitoring for high-risk populations. Despite the low incidence, early unplanned re-operations impose substantial clinical and economic burdens, supporting national initiatives such as GIRFT that emphasize reducing avoidable complications.
This institutional benchmarking study provides valuable insights into modifiable risk factors and highlights priority areas for improving trauma care outcomes, resource allocation, and clinical governance.
