PURPOSE: To assess the risk of surgical delay in elderly hip fracture patients on anti-platelet agents. METHODS: Records of 180 patients aged over 65 years with either an intertrochanteric or femoral neck fracture were reviewed. The clopidogrel group included 10 patients on clopidogrel alone and 11 others on clopidogrel and aspirin, whereas the control group included 69 on aspirin alone and the remaining 90 not on any anti-coagulants. The 2 groups were compared with regard to time to surgery, preoperative American Society of Anesthesiologists (ASA) score, pre- and post-operative haemoglobin levels, in-patient complication rates, duration of hospital stay, and 30-day mortality. RESULTS: In the clopidogrel and control groups respectively, the mean times to surgery were 7.2 and 2.1 days (p=0.03, t-test), the mean preoperative ASA scores were 3.35 and 2.8 (p=0.29, t-test), the mean preoperative haemoglobin levels were 119 and 115 g/l (p=0.5, t-test), the mean postoperative haemoglobin levels were 98 and 96 g/l (p=0.68, t-test), the mean durations of hospital stay were 7.4 and 3.1 days (p=0.02, t-test). The 30-day mortalities were 6/21 (29%) and 6/159 (4%) [p=0.0003, Fisher's exact test]. CONCLUSION: Surgical delay in elderly patients on anti-platelet agents with hip fracture was associated with higher mortality. Despite the risk of increased blood loss, we suggest early surgery be carried out by an experienced surgeon to expedite the operating time. Pooled platelets should be given intravenously one to 2 hours preoperatively.
