[Medial femoral neck fractures: possible reasons for delayed surgery. Part 2: Results of data from external inpatient quality assurance within the framework of secondary data evaluation].

PROBLEM: In Germany a disproportionate number of patients with a femoral neck fracture still experience a delay in surgery. In 2008 delays of more than 48 h after admission occurred for 15.4 % of patients. This leads to increases in surgical and general complications as well as pressure sores. OBJECTIVE: Possible reasons that lead to delayed operations were investigated in a nationwide study. DATA AND METHODS: Using nationwide data from the German inpatient external quality assurance program from the year 2008 the reasons for performing operations later than 48 h after hospital admission were examined both exploratory and analytically using a multiple logistic regression model considering combined effects. RESULTS: Surgery was more frequently delayed for patients who were admitted to hospital on Friday or Saturday, patients with a higher American Society of Anesthesiologists (ASA) classification, men, patients with malignant diseases, in the presence of infectious diseases and patients with heart disease. Operations carried out within the first 48 h were more frequent with displaced fractures and in the presence of hypertension or mental illness. The volume per hospital had no consistent effect on the time delay of surgery. During the week no significant differences between the departments were detected. On Friday or Saturday surgery was delayed more often when patients were admitted to a department of general surgery than to a department of trauma surgery or orthopedics. CONCLUSIONS: There are medical and non-medical reasons for delayed surgery of femoral neck fractures. Studies have confirmed that delayed surgery for femoral neck fracture harms the patients. Organizational reasons which prevent an immediate operation, e.g. admission on Friday or Saturday, should therefore be eliminated by improvements in hospital organization and staffing. These can be measures of individual hospitals or of several hospitals in cooperation. The target should be to ensure a comprehensive and timely provision of the highest quality care even at the weekend.
