RESUMEN
OBJECTIVE: Identify risk factors associated with prolonged hospital stay (LOS more than 14 days) in patients with osteoporotic hip fracture. MATERIAL AND METHOD: One hundred and fifty out of 356 patients with fractured femur were selected between April 2008 and August 2009. Analysis of patient's LOS (group I equal or less than 14 days, group II more than 14 days) is performed by backward binary multiple logistic regression. RESULTS: LOS in group I (n=46) was 12.5 (+/- 4) days compared to 21 (+/- 11) days in group II (n=104). Patients were mainly female (74%) and about 50% were aged over 80 years. The 30-days mortality in group I and II was zero and two patients respectively. Time-to-surgery was three days (+/- 2) in group I and seven (+/- 5) days in group II. Significant predicting risk factors were waiting for investigation (odds ratio (OR) 3.77, confidence interval (CI) 1.12-12.69) and receiving systemic opioids (OR 3.44; CI 1.54-7.66). CONCLUSION: Unnecessary surgery delay after hip fracture should be avoided. Higher need for opioids in those patients might be the result of prolonged waiting for surgical treatment.
