title: Predictors of not regaining basic mobility after hip fracture surgery.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
