Objectives-We sought to examine the relationship between functional outcome and process of care for patients with hip fracture.Research Design and Participants-We undertook a prospective cohort study in 4 hospitals of 554 patients treated with surgery for hip fracture.Measurements-Information on patient characteristics and processes of hospital care collected from the medical record, interviews, and bedside observations. Follow-up information obtained at 6 months on function (using the Functional Independence Measure [FIM]), survival, and readmission.Results-Individual processes of care were generally not associated with adjusted outcomes. A scale of 9 processes related to mobilization was associated with improved adjusted locomotion (P = 0.006), self care (P = 0.022), and transferring (P = 0.007) at 2 months, but the benefits were smaller and not significant by 6 months. These processes were not associated with mortality. The predicted value for the FIM locomotion measure (range, 2-14) at 2 months was 5.9 (95% confidence interval 5.4-6.4) for patients at the 10th percentile of performance on these processes compared with 7.1 (95% confidence interval 6.6, 7.6) at the 90th percentile. Patients who experienced no hospital complications and no readmissions retained the benefits in locomotion at 6 months. Anticoagulation processes were associated with improved transferring at 2 months (P = 0.046) but anticoagulation and other processes of care were not otherwise associated with improved function.
