AbstractPURPOSE OF THE STUDY The increasing number of hip fractures puts enormous demand on our level 1 trauma centre. Because we have to synchronize hip fracture treatment with all other injuries delays to surgery can occur. In this study, we analysed the reasons for delay to surgery and how it impacts on mortality of hip fracture patients in our institution. MATERIAL AND METHODS We retrospectively studied 641 patients operated for hip fractures in one year period. Investigated characteristics were: age, gender, American Society of Anaesthesiologists score (ASA), time of hospital admission, time of surgery, type of surgery, anticoagulant therapy (ACT) and non-routine pre-operative tests (NRPT). Trochanteric (TF) and femoral neck fractures (FNF) were analysed separately. The surgery in first 48 hours was considered early. The time of death was obtained from the federal database. Univariate and multivariable analysis were performed. P-values <0.05 were considered statistically significant. RESULTS All tested characteristics were significantly different in both time groups. Delay to surgery was significantly influenced by the type of surgery - arthroplasty, odds ratio (OR) 17.2, ACT (OR 6.9) and NRPT (OR 4.0) in FNF group of patients and by ACT (OR 31.1) and ASA (OR 2.2) in TF. 30-day mortality rate was 5.1% and 1-year mortality was 18.4%. ASA (OR 1.9), preinjury residence (OR 1.4) and age (OR 1.1) had statistical influence on survival, but not delay to surgery. CONCLUSIONS The majority of delays are due to unavailability of operative capacities, after patient optimization. We see solution in dedicated operation rooms and teams for hip fracture treatment. Mortality is influenced by the patients' characteristics, but not by delay to surgery. A multidisciplinary approach and skilled surgical teams are, besides early operation, the most important assurance of a good outcome. Key words: trochanteric fracture, femoral neck fracture, timing, mortality.
