1459 HANDGRIP STRENGTH AS A PREDICTOR OF POST-OPERATIVE OUTCOMES FOLLOWING HIP FRACTURE

Abstract Introduction Sarcopenia is common in patients with hip fracture, but few studies have examined whether assessment of sarcopenia improves prediction of adverse post-operative outcomes. We examined whether sarcopenia, diagnosed using hand grip strength (HGS), could predict outcomes after hip...

Description
Summary:Abstract Introduction Sarcopenia is common in patients with hip fracture, but few studies have examined whether assessment of sarcopenia improves prediction of adverse post-operative outcomes. We examined whether sarcopenia, diagnosed using hand grip strength (HGS), could predict outcomes after hip fracture. Methods Routinely collected data from the National Hip Fracture Database were combined with locally collected HGS data from a high-volume orthopaedic trauma unit. Patients aged ≥65years with surgically managed, non-pathological hip fracture with grip strength measured on admission were included. The European Working Group on Sarcopenia in Older People (EWGSOP2) thresholds were used to identify patients with or without sarcopenia; those unable to complete grip strength testing were also included in analyses. Outcomes examined were 30-day and 120-day mortality, residential status and mobility, prolonged length of stay (>15 days) and post-operative delirium. Binary logistic regression models were used to examine prognostic value of HGS, and discriminant ability for the Nottingham Hip Fracture Score (NHFS) alone and on adding sarcopenia status were compared using c-statistics. Results We analysed data from 282 individuals; mean age 83.2 (SD 9.2) years; 200 (70.9%) were female. 99 (35.1%) patients had sarcopenia and 109 (38.7%) were unable to complete testing. Sarcopenia predicted higher 120-day mortality (OR 13.0, 95%CI 1.7-101.1, p=0.014), but not 30-day mortality (OR 1.5, 95%CI 0.1-16.9, p=0.74). Patients unable to complete HGS testing had higher 30-day mortality (OR 13.5, 95%CI 1.8-103.8, p=0.012) and 120-day mortality (OR 34.5, 95%CI 4.6-258.7, p
