Abstract
BACKGROUND AND OBJECTIVES
Osteoporotic hip fracture is a relevant pathology due to its prevalence and social and health impact. The aim of this study is to explore the predictive validity of the CUPAX questionnaire on mortality, place of residence and post-fracture functionality.
MATERIALS AND METHODS
Prospective observational study. Two hundred and six patients older than 65 years were included, admitted after a hip fracture. The CUPAX questionnaire score was collected before fracture and one year later, and the place of residence and survival at hospital discharge, and after 6 and 12 months. The statistical analysis was carried out with the SAS® 9.4 and Stata® 13.1 programmes.
RESULTS
The median age of the sample was 87.0 years (80.1% women). The in-hospital and one-year mortality rate were 5.8% and 19.1%, respectively. Most of the patients were admitted from home (71.4%), and the most frequent discharge destination was a social health centre (48.2%). The percentage of retention of previous functional level in the total sample was 50%, being higher in the younger patients. The area under the curve ROC for mortality one year later was .697 (95% CI .626-.760) and .659 (95% CI .576-.741) for the discharge destination of patients admitted from home. Evaluation of functional retention one year after the fracture, identified three groups of patients based on the pre-fracture CUPAX value.
CONCLUSIONS
These findings support the clinical utility of the CUPAX questionnaire as a predictive functional tool in elderly patients with hip fracture.
