The Safety of Continuing Antiplatelet Medication Among Elderly Patients Undergoing Urgent Hip Fracture Surgery.

This study sought to elucidate the safety of urgent hip surgery without termination of antiplatelet medication among patients taking a combination of aspirin and dipyridamole, aspirin alone, or dipyridamole alone. This retrospective cohort study included 176 patients 55 years or older who had uncomplicated hip fractures and underwent surgery within 48 hours after admission. On the basis of the preoperative medication regimen, the patients were divided into the following 4 groups: those receiving aspirin and dipyridamole combined (n=29); those receiving aspirin alone (n=63); those receiving dipyridamole alone (n=28); and those not receiving antiplatelet medication (n=56). Main outcomes, including total blood loss, transfusion rate, and 1-year mortality, were analyzed. There was no significant difference in total blood loss, transfusion rate, or 1-year mortality among the 4 groups. The group receiving aspirin and dipyridamole combined preoperatively had increased intraoperative blood loss (mean, 309.14±189.15 mL) compared with the group not receiving antiplatelet medication (mean, 214.64±119.21 mL; P=.005). There was no significant difference in the hazard ratio (P>.05) for 1-year mortality among the 4 groups after adjusting for confounding covariates, including age, sex, Charlson Comorbidity Index, and duration of hospital stay. Patients receiving antiplatelet medication, including aspirin, dipyridamole, or both, who have uncomplicated hip fractures may undergo urgent sur...
