Functional outcome in patients with hip fracture from 2008 to 2018, and the significance of hand-grip strength – a cross-sectional comparative study

[摘要] BackgroundIncidence of hip fracture is estimated to rise, increasing demands on healthcare. Our objective was to compare patients with hip fracture, a decade apart, regarding surgical characteristics and functional outcome in relation to morbidity. A secondary aim was to analyse postoperative hand-grip strength (HGS) in relation to walking ability 4 months postoperatively.MethodsThis is a cross-sectional comparative study of patients with hip fracture, included in 2008 (n = 78) and 2018 (n = 76) at Örebro University Hospital. Patient-data (age, gender, morbidity, fall-circumstances, fracture, surgical characteristics, and length of stay) were collected from medical records. HGS was measured postoperatively. Data on functional outcome in terms of housing, walking ability and need of walking aids at 4 months postoperatively was collected from the Swedish Hip Fracture Register RIKSHÖFT. Statistical analyses adapted were hypothesis tests and regression analysis.ResultsPatients in 2018 presented a significantly higher morbidity than patients in 2008 and there were significant differences in adapted surgical methods. Functional outcome at 4-months postoperatively was analysed by logistic regression where Cohort 2018 was associated with higher odds of independent walking ability (OR 5.7; 95%CI 1.9–17.2) and not needing any walking aids (OR 5.1; 95%CI 1.9–17.2). Postoperative HGS was higher among patients in 2018 and a multiple regression analysis revealed a significant association between HGS and walking ability at 4 months postoperatively.ConclusionsThis study supports the since previously reported development in hip fracture surgery in Sweden while also presenting that functional outcome seems to have improved despite a concomitant increase in morbidity. Results suggest an improvement in postoperative HGS, predicting walking ability at 4 months postoperatively.
