Background: the impact of anaemia on the outcome after a hip fracture surgery is controversial, but anaemia can potentially decrease the physical performance and thereby impede post-operative rehabilitation. We therefore conducted a prospective study to establish whether anaemia affected functional mobility in the early post-operative phase after a hip fracture surgery. Patients and Methods: four hundred and eighty seven consecutive hip fracture patients, treated according to a well-defined multimodal rehabilitation programme with a uniform, liberal transfusion threshold, were studied. Hb was measured on each of the first three post-operative days, and anaemia defined as Hb <100 g/l. Functional mobility was measured with the Cumulated Ambulation Score (CAS). Results: the results were obtained from 170, 132 and 116 patients who were found anaemic on the first, second and third post-operative day, respectively. A significant association between anaemia and the ability to walk independently before the correction of anaemia was present on each of the 3 days separately ( P <0.05). A significant correlation was also found on each day between the functional score and the Hb level. A multivariate analysis integrating the type of surgery, medical complications and prefracture function showed that anaemia at the time of the physiotherapy session was an independent risk factor for not being able to walk on the third post-operative day [OR 0.41 (0.14–0.73) P = 0.002]. Conclusion: anaemia impedes functional mobility in the early post-operative phase after a hip fracture surgery and is an independent risk factor for patients not being able to walk post-operatively. The potential for a liberal transfusion policy to improve the rehabilitation potential in hip fracture patients with anaemia should be investigated.

Objective: To validate the cumulated ambulation score as an early postoperative predictor of short-term outcome in hip fracture patients. Design: Prospective, descriptive study. Setting: An orthopaedic hip fracture unit in a university hospital. Patients: Four hundred and twenty-six consecutive hip fracture patients with an independent walking function admitted from their own home. Rehabilitation followed a well-defined multimodal rehabilitation regimen and discharge criteria. Main outcome measure: Admission tests with a new mobility score to assess prefracture functional mobility and a short mental score for cognitive dysfunction were performed. On the first three postoperative days patients were assessed with the cumulated ambulation score consisting of a cumulated assessment of simple ambulation characteristics with a score from 0 to18 (fully mobile). The three assessments were correlated to short-term outcome parameters. Results: The cumulated ambulation score was a highly significant predictor for length of hospitalization, time to discharge status, 30-day mortality and postoperative medical complications (P < 0.001 for all). The cumulated ambulation score was superior in its association with all postoperative outcome parameters to both the New Mobility Score and the mental score. A cumulated ambulation score of ±10 correlated with a 99% survival at one month and 93% discharge to own home. Conclusion: The cumulated ambulation score is a potentially valuable score for early prediction of short-term postoperative outcome after hip fracture surgery.

Clinicians need valid and easily applicable predictors of outcome in patients with hip fracture. Adjusting for previously established predictors, we determined the predictive value of the New Mobility score (NMS) for in-hospital outcome in patients with hip fracture. We studied 280 patients with a median age of 81 (interquartile range 72-86) years who were admitted from their own homes to a special hip fracture unit. Main outcome was the regain of independence in basic mobility, defined as. independence in getting in and out of bed, sitting down and standing up from a chair, and walking with an appropriate walking aid. The Cumulated Ambulation score was used to evaluate basic mobility. Predictor variables were NMS functional level before fracture, age, sex, fracture type, and mental and health status. Except for sex, all predictor variables were statistically significant in univariate testing. In multiple logistic regression analysis, only age, NMS functional level before fracture, and fracture type were significant. Thus, patients with a low prefracture NMS and/or an intertrochanteric fracture would be 18 and 4 times more likely not to regain independence in basic mobility during the hospital stay, respectively, than patients with a high prefracture level and a cervical fracture, respectively. The model was statistically stable and correctly classified 84% of cases. The NMS functional level before fracture, age, and fracture type facilitate prediction of the in-hospital rehabilitation potential after hip fracture surgery.

Background and Purpose Previous studies of Timed “Up & Go” Test (TUG) scores as a predictor of falls were based primarily on retrospective data, and no prospective studies of the TUG for predicting falls in people with hip fracture are available. The purpose of this study was to determine whether TUG scores obtained upon discharge from an acute orthopedic hip fracture unit can predict falls in people with hip fracture during a 6-month follow-up period. Subjects The subjects included in this study were 79 consecutive elderly people who had hip fractures and were able to perform the TUG when discharged directly to their own homes or to assisted living facilities from a specialized acute orthopedic hip fracture unit, with 59 (75%) being able to participate in the follow-up interview. Methods In this prospective study, all subjects were contacted for a 6-month follow-up interview about falls since discharge from the hospital. The score on the TUG performed at discharge (median of 10 days after surgery) was compared with the New Mobility Score, which describes functional level before the fracture and mental status on admission, sex, type of fracture, residence, and walking aids before and after the fracture. All subjects followed a well-defined care plan with multimodal fast-track rehabilitation including an intensive physical therapy program comprising 2 daily sessions; discharge was in accordance with standardized criteria. Analyses and correlations of all variables were examined for prediction of falls, and sensitivity, specificity, predictive values, and likelihood ratios were calculated. Falls were classified as “none” or as “1 or more.” Results Among the 59 subjects in the follow-up group, 19 subjects (32%) experienced 1 or more falls in the period since discharge; 4 of these falls resulted in new hip fractures. The TUG performed at discharge with a cutoff point of 24 seconds was the only parameter that significantly predicted falls during the 6-month follow-up period, with a negative likelihood ratio of 0.1 to be a faller as a nonfaller. Discussion and Conclusion The results suggest that the TUG is a sensitive measure for identifying people with hip fracture at risk for new falls, and it should be part of future outcome measures to decide for whom preventive measures against falls should be instituted.
