154 The Feasibility of Assessing Sarcopenia Among Older People with Arm Fracture Using Different Criteria

Osteoporosis and sarcopenia often co-exist (osteo-sarcopenia) and both are associated with increased risk of falls and fractures. Early identification and treatment of sarcopenia among older people with fragility arm fractures could prevent further fractures. This study evaluated the feasibility of assessing sarcopenia in a fracture clinic. Methods People aged 65+ years with arm fracture attending fracture clinics in one acute trust were recruited. Sarcopenia was assessed using gait speed, grip strength with unfractured arm (hand dynamometer using appropriate cut off adjusted for age and gender), skeletal muscle mass index SMI (Bioimpedance BIA), SARC-F questionnaire, the European Working Group on Sarcopenia in Older People (EWGSOP) I and II criteria. The sensitivity and specificity of each measure was calculated against the EWGSOP II criteria as the standard reference. Results 100 patients (Mean age 75 years±7.2; 80 female) were recruited. Sarcopenia was identified among 4% (EWGSOP I), 5% (SMI), 13% (EWGSOP II), 16% (gait speed test), 18% (SARC-F) and 39% (grip strength) and was more prevalent among men. SARC-F had the best sensitivity and specificity (100% and 96% respectively) when compared to the EWGSOP II criteria. Sensitivity and specificity for the remaining measures were respectively (100%, 71%) for grip strength, (75%, 94%) for gait speed, (25%, 97%) with SMI and (25%, 99%) for EWGSOP I. Time needed to complete the assessments was 1–2 minutes for gait speed, grip strength and SARC-F; five minutes for BIA test, and nine minutes when EWGSOP I and II criteria were applied. Data were complete for grip strength and SARC-F. Missing data was reported among 2% for gait speed, 8% for BIA test, 8% for EWGSOP II and 10% for EWGSOP I. Conclusion It was feasible to assess sarcopenia in fracture clinics and SARC-F was a quick, simple and sensitive tool suitable for routine use.
