Validation of the SARC-F for Assessing Sarcopenia in Patients on Peritoneal Dialysis

Objective Proper screening or diagnosis of sarcopenia (SP) is important to obtain favorable outcomes in patients on peritoneal dialysis (PD). Previous studies have shown that the SARC-F is associated with various parameters of SP in elderly populations. In this study, we aimed to validate the SARC-F questionnaire for predicting SP in patients on PD. Methods This cross-sectional study was conducted at a tertiary medical center. We identified all patients prevalent on PD patients (n = 127). A version of the original SARC-F was used to assess the questionnaire. Patients with a total score of ≥4 points were defined as the high group and those with Results Of the 127 total patients, 29 (22.8%, high group) had an SARC-F score of ≥4. The sensitivity and specificity of the SARC-F for predicting SP were 70.0% and 81.2%, respectively. The negative predictive and positive predictive values were 96.9% and 24.1%, respectively. The area under curve of the SARC-F score for SP was 0.791 (0.709-0.858, P  Conclusion The SARC-F has a high negative predictive value and a high specificity for predicting SP in patients on PD.
