Predictors of not regaining basic mobility after hip fracture surgery

Abstract

Purpose: Regaining basic mobility after hip fracture surgery is a milestone in the in-hospital rehabilitation. The aims were to investigate predictors for not regaining basic mobility at the fifth post-operative day and at discharge after undergoing hip fracture surgery. Method: In a prospective cohort study 274 hip fracture patients were included. Patients with compromised ability to exercise were excluded leaving 167 patients for analysis. Patient demographics, functional level, method of operation, post-operative hemoglobin and the completion of physiotherapy was registered. Basic mobility was assessed by the Cumulated Ambulation Score. Multivariate logistic regression was performed. Results: Age >80 years (OR = 7.5), low prefracture functional level (OR = 3.0), not completed the physiotherapy on first post-operative day (OR = 4.6) and hemoglobin <6 mmol/L measured on first post-operative day (OR = 5.8) were significant predictors of not regaining basic mobility within the fifth post-operative day (p values: 0.04–<0.0001). Predictors of not regaining basic mobility at discharge were: Age >80 years (OR = 4.3), prefracture functional level (OR = 7.0) and not completed the physiotherapy on first post-operative day (OR = 3.3) (p values: 0.009–<0.0001). Conclusions: This study shows that patients undergoing hip fracture surgery, who are not able to complete physiotherapy on first post-operative day, are at a greater risk of not regaining basic mobility during hospitalization. This highlights the importance of physiotherapy as part of the interdisciplinary treatment.

Implications for Rehabilitation

• Regaining abilities in basic mobility after hip fracture surgery is a primary goal of rehabilitation during hospitalization in the acute ward.

• The following factors are indentified to predict patients not regaining their previous level of basic mobility: Age >80 years, low prefracture functional level, patients not being able to complete the physiotherapy on the first post-operative day and hemoglobin value <6 mmol/l on the first post-operative day.

• In future strategies, the findings regarding both modifiable and unmodifiable factors, can be used to conduct early planning of discharge and to take actions in relation to patients who are at a risk of not regaining basic mobility.
