Days alive and at home after hip fracture: a cross-sectional validation of a patient-centred outcome measure using routinely collected data

Background Days alive and at home (DAH) is a patient centered outcome measureable in routinely collected health data. The validity minimally important difference (MID) hip fracture have not been evaluated. Objective We assessed construct predictive estimated MID for the patient-centred of DAH after admission. Methods This cross-sectional observational study using linked administrative data Ontario, Canada. was calculated as number days within 90 admission minus hospitalised or institutionalised. All hospital admissions (2012–2018) adults aged >50 years were included. Construct analyses used Bayesian quantile regression to estimate associations postulated patient, process-related variables with DAH. correlation value from 91 365 days; association discrimination predicting subsequent mortality. by averaging distribution-based clinical anchor-based estimates. Results identified 63 778 patients fracture. median 43 (range 0–87). In admission, 8050 (12.6%) people died; further 6366 (10.0%) died 365. Associations between patient-level admission-level factors (lower greater age, frailty comorbidity, lower if admitted intensive care having had complication) supported validity. strongly correlated (r=0.922). An 11-day estimated. Conclusion has face, fracture, an 11 days. Future research required include direct perspectives confirming MID.
