Fragility hip fractures are associated with increased morbidity, mortality, and costs. To improve patient care, quality indicator programs were introduced. Yet, the efficacy of these programs and specific quality indicators are questioned. We aimed to determine whether defining prophylactic pre-surgical antibiotic treatment as a quality indicator affected hip fracture outcomes. A retrospective study comparing consecutive patients, 65 years and older, who were operated for fragility hip fractures between 01/01/2011 and 30/06/2016, before and after the prophylactic pre-surgical antibiotic treatment quality indicator, which was introduced in 01/2014. Primary outcomes were 1-year surgical site infections (SSI). Secondary outcomes were meeting the quality index and mortality rates, either within a hospital or during the first post-operative year. 904 patients, ages 82.5 ± 7.2 years were operated for fragility hip fractures. 403 patients presented before the antibiotic prophylaxis quality indicator, and 501 following its administration. Patients demographics were comparable. In the pre-quality indicator period, documentation of prophylactic antibiotic treatment was lacking. Only 19.6% had a record for antibiotic administration in their surgical records and for merely 10.4% the type of antibiotic was stated. However, in the post-quality indicator period, 97.0% of patients had a registered prophylactic antibiotic regimen in the hour preceding the surgical incision (p  < 0.001). Post-operative SSI rates were equivalent, and as were in-hospital infections, mortality and recurrent hospitalizations The introduction of the pre-operative antibiotic treatment quality indicator increased the documentation of antibiotic administration yet failed to influence the incidence of post-operative orthopaedic and medical infections in fragility hip fracture patients.
