ObjectivesTo correlate analgesia use among patients with hip fracture requiring surgery with hip fracture subtype, cognitive status, and type of surgery in the postacute period.Design And ParticipantsProspective review of patients with hip fractures requiring surgical intervention. A total of 415 patients (mean age: 81.2 ± 9.1 years, 74.3% women) presented with 195 subcapital fractures (39 undisplaced, 156 displaced) and 220 trochanteric fractures (136 stable, 84 unstable) requiring surgery.SettingInpatient orthopedic units in 4 Australian hospitals.MeasurementsThe primary outcome measures were mean analgesia usage (oral morphine equivalent) for 4 defined time intervals and total amount 36 hours following surgery.ResultsPatients with subtrochanteric fractures required more analgesia compared with displaced-subcapital, undisplaced-subcapital, basicervical, stable-pertrochanteric, and unstable-pertrochanteric fractures in the 24 to 36 hours following operation (24.7 vs 11.3 vs 8.8 vs 12.1 vs 7.6 vs 9.7, P = .001). Total analgesia requirements were higher in patients treated with an intramedullary nail, increasing by 1.3- to 3.3-fold in the 36 hours postsurgery. Patients with cognitive impairment utilized markedly less analgesia at all time periods measured. At 24 to 36 hours, higher levels of analgesia were noted in patients with higher premorbid level of mobility (P = .015) and activities of daily living function (P = .007).ConclusionImportant differences in utilization of analgesia following hip fracture across readily defined clinical groups exist. Proactive pain management for those with cognitive impairment, certain hip fracture subtypes, and surgical procedures may enable early functional mobility and other activities.
