Proximal Femur Fractures: Evaluating the Necessity of On-Call Surgery

<b>Background:</b> The decision of the Joint Federal Committee on the treatment of hip fractures stipulates that proximal femur fractures must be treated within the first 24 h. This leads to organizational and personnel difficulties in day-to-day care. Therefore, we investigated the question at what times of day we operate to maintain this timeline and whether there is a difference in the outcome for the patients according to treatment hours. <b>Methods:</b> Data from the DGU's "AltersTraumaRegister" from 2016 to 2020 were analyzed. For the analysis, the patients were divided into seven cohorts depending on the time of surgery. Pre-operative, operative, and follow-up data were analyzed. <b>Results:</b> A total of 29,470 patients were included in our study. The results showed that 74% of patients were treated within 24 h. 72% of patients operated on between 0-7 h had pertrochanteric fractures, while 56% of all arthroplasties were performed during normal working hours. In supra-regional trauma centers, significantly fewer operations were performed during normal working hours, while significantly more surgeries were carried out in the late evening and at night (<i>p</i> < 0.001). There were no significant differences in mortality and morbidity between the individual groups. <b>Conclusions:</b> Although we manage to treat most patients within 24 h, only 46% of patients are operated on within normal working hours. In terms of the outcome parameters, this does not appear to be a disadvantage for the patients. Nevertheless, night work and fatigue affect concentration and post-operative results in many areas, as we know. Consequently, patient care during normal working hours within 24 h creates the best possible initial situation for the patient, as significantly more personnel resources are available during normal working hours. The aim should be to create the logistical and personnel requirements for this.
