PURPOSE: To identify factors predicting one-year mortality in patients on clopidogrel presenting with proximal femoral fractures.
METHODS: 9 men and 22 women aged 64 to 97 (mean, 81; standard deviation, 8) years who had been taking clopidogrel for ischaemic heart disease (n=15), cerebrovascular disease (n=6), or both (n=10) presented with proximal femoral fractures. The time from injury to operation, type of anaesthesia, treatment method, and postoperative complications were reviewed. One-year mortality was analysed using the Kaplan-Meier curve. Factors predicting one-year mortality were identified.
RESULTS: The fracture configurations of the 31 patients included intracapsular femoral neck fracture (n=17), intertrochanteric fracture (n=13), and subtrochanteric fracture (n=1). 30 of the patients underwent hemiarthroplasty (n=16), dynamic hip screw fixation (n=9) or intramedullary hip screw fixation (n=5). The remaining patient underwent conservative treatment owing to metastatic prostate cancer. Of the 30 patients who underwent surgery, clopidogrel was discontinued at least 7 days prior to surgery, with the mean delay to surgery being 8.4 (range, 2-16) days. No patient had excessive blood loss at operation, although 7 patients received a blood transfusion postoperatively. 13 (43%) patients developed postoperative complications. The one-year mortality was 26% (8/31). Univariate analysis showed that factors predicting one-year mortality were spinal anaesthesia (p=0.04), postoperative blood transfusion (p=0.03), postoperative complications (p=0.03), and delay to surgery (p=0.03). Multiple regression analysis showed that delay to surgery (p=0.03) was the only independent predictor of one-year mortality, with a hazard ratio of 1.357 (95% confidence interval, 1.03-1.79).
CONCLUSION: Surgery should be performed as soon as possible in medically fit patients having proximal femoral fractures who are taking clopidogrel, as delay to surgery is associated with increased one-year mortality.
