Previous studies have shown that preoperative factors predict the postoperative Barthel Index score in patients with trochanteric fractures, while there is less evidence on the effects of perioperative factors on the prediction. This study aimed to assess the effects of preoperative and perioperative factors on the early postoperative Barthel Index score in patients with trochanteric fractures. Consecutive 288 patients aged ≥60 years with trochanteric fractures who could independently walk before injury were included. Patients were grouped according to the Barthel Index score measured after 2 weeks of surgery; the cut-off value was 20 points. Two logistic regression models were created to assess the effects of preoperative (model 1: dementia, walking ability before injury, and nutrition status) and perioperative (model 2: independent variables in model 1, reduction quality, and basic mobility function) factors on the Barthel Index score. Sensitivity and specificity were used to assess the predicative accuracy of the models. Poor preoperative (model 1: χ2= 34.626, P < 0.01) and perioperative (model 2: χ2= 43.956, P < 0.01) characteristics were significantly related to lower Barthel Index score. Sensitivity and specificity were similar between the models (model 1: 83.3% and 38.9% and model 2: 82.2% and 42.6%, respectively). Both preoperative and perioperative factors were significantly related to the early postoperative Barthel Index score after trochanteric fracture. However, only minimal increase in predictive accuracy was observed when perioperative predictors were analyzed along with preoperative factors. Both baseline characteristics and basic postoperative mobility should be considered when treating patients with trochanteric fractures.
