OBJECTIVE. To identify predictors of rehabilitation outcomes for the development of a case-mix system to rehabilitate patients suffering from hip fractures.
DESIGN. Prospective cohort study.
SETTING. Two hospitals in Hong Kong.
PATIENTS. A cohort of hip fracture patients in 2005 (n=303) with a mean age of 82 years was studied. Rehabilitation outcomes were defined as: mortality, length of stay, placement, ambulation status, activity of daily living at the time of discharge and at 6-month follow-up. A comparison between groups and multivariate analysis was conducted to validate the best predictors.
MAIN OUTCOME MEASURES. Potential predictors and rehabilitation outcomes.
RESULTS. Two predictors, the Abbreviated Mental Test score of lower than 6 (odds ratio=0.19, P
CONCLUSION. A case-mix system utilising the cognition and activity of daily living function is recommended. Revisions of respective care plans are advocated with more realistic outcome expectations and specific actions for the respective case-mix groups. An evaluation study on the usefulness of this case-mix classification could then follow.
