Predicting discharge location of hip fracture patients; the new discharge of hip fracture patients score

Purpose This paper reports on the development and validity of a new instrument, called the discharge of hip fracture patients score (DHP), that predicts at admission the discharge location in patients living in their own home prior to hip fracture surgery. Methods A total of 310 patients aged 50 years and above were included. Risk factors for discharge to an alternative location (DAL) were analysed with a multivariable regression analysis taking the admission variables into account with different weights based on the estimates. The score ranged from 0-100 points. The cut-off point for DAL was calculated using a ROC analysis. Reliability of the DHP was evaluated. Results Risk factors for DAL were higher age, female gender, dementia, absence of a partner and a limited level of mobility. The cut-off point was set at 30 points, with a sensitivity of 83.8%, a specificity of 64.7% and positive predictive value of 79.2%. Conclusion The DHP is a valid, simple and short instrument to be used at admission to predict discharge location of hip fracture patients

Risk factors for failure to return to the pre-fracture place of residence after hip fracture: a prospective longitudinal study of 444 patients

Introduction: Long-term place of residence after hip fracture is not often described in literature. The goal of this study was to identify risk factors, known at admission, for failure to return to the pre-fracture place of residence of hip fracture patients in the Wrst year after a hip fracture. Methods: This is a prospective longitudinal study of 444 consecutive admissions of hip fracture patients aged ≥65 years. Place of residence prior to admission, at discharge, after 3 and 12 months was registered. Patients admitted from a nursing home (n = 49) were excluded from statistical analysis. Multivariable logistic regression analysis was performed, using age, gender, presence of a partner, ASAscore, dementia, anaemia at admission, type of fracture, pre-fracture level of mobility and level of activities of daily living (ADL) as possible risk factors. Results: Two hundred eighty-nine patients lived in their own home, 31.8% returned at discharge, 72.9% at 3 months and 72.8% at 12 months. Age, absence of a partner, dementia, and a lower pre-fracture level of ADL or mobility were independent contributors to failure to return to their own home at discharge, 3 or 12 months. 106 patients lived in a residential home; 33.3% returned at discharge, 68.4% at 3 months and 64.4% at 12 months. Age was an independent contributor to failure to return to a residential home. Conclusions: Age, dementia and a lower pre-fracture level of ADL were the main signiWcant risk factors for failure to return to the pre-fracture residence. As the 3- and 12-month return-rates were similar, 3-month follow-up might be used as an endpoint in future research

Arthroplasty or internal fixation for displaced femoral neck fractures: which is the optimal alternative for elderly patients? A meta-analysis

We conducted an up-to-date meta-analysis of 20 eligible randomised controlled trials (RCTs) containing 3,109 patients to compare arthroplasty with internal fixation of displaced femoral neck fractures regarding the effect on clinical outcomes. Computerised databases were searched for RCTs published from January 1979 to May 2008. The results showed that compared to internal fixation arthroplasty led to significantly fewer surgical complications at two and five years postoperatively and reduced the incidence of reoperation at one, two and five years postoperatively (P < 0.001). However, arthroplasty was associated with greater risk of deep wound infection, longer operating time and greater operative blood loss. Arthroplasty substantially increased the risk of reoperation following deep wound infection (P < 0.05). For mortality, there was increased postoperative risk for arthroplasty compared with internal fixation, but there was no statistically significant difference between the two groups at the different follow-up times. For pain at one year postoperatively, the result showed no statistically significant difference
