Minimizing the Risk of Surgical Site Infection Following Hip Fracture Operation.

Introduction: Hip fractures are the most common serious injury in the elderly, associated with disability, morbidity, and mortality. Surgical site infection (SSI) is a serious post-operative complication. This prospective cohort study outlines how our center made cumulative improvements in SSI incidence rates, reaching a 12-month average of 0.5%. Methods: All patients undergoing hip fracture operation between 2016 and 2021 were included. The primary outcome measure was confirmed SSI, according to the Public Health England definition. Results were compared with the baseline recordings by an independent SSI team in 2013. Demographic data were compared with National Hip Fracture Database records. Peri-operative infection control and wound management tactics introduced between 2014 and 2021 were collated to gain an overview care bundle. Results: Baseline recordings identified a 9.0% SSI rate in a three-month observation period. In our study, 3,138 hip fracture operative cases were completed between October 2016 and December 2021. There were 9 superficial and 32 deep infections identified, yielding an overall infection rate of 1.3%. However, when analyzing the 12-month average, there was consistent decline in SSI from the baseline 9.0% in 2013 to 0.5% in 2021 (p < 0.05). A peri-operative care bundle included pre-operative bleeding risk assessment. Intra-operatively, double preparation and draping is used for arthroplasty. Broad-spectrum antibiotic agents and tranexamic acid are administered. Meticulous hemostasis and watertight wound closure are observed. Anti-coagulated patients received negative pressure dressings. Post-operatively, a dedicated senior lead team provided daily inpatient review of patients, with urgent consultant review of all wound healing concerns. Conclusion: Patients with a hip fracture have numerous risk factors for SSI. A dedicated multi-focal tactic, adopted by a multi-disciplinary department, can yield substantial risk reduction. Each intervention is evidence based and contributes to cumulative improvement. By prioritizing infection prevention, we have minimized the need for complex infection management interventions and achieved an annual saving of £860,000 for our trust.
