Screening of sarcopenia of haemodialysis patients

Abstract

The informativity of the screening method of sarcopenia «Strength, Assistance, Rise, Climb, Fall» in haemodialysis patients was evaluated. When diagnosing sarcopenia according to the recommendations of the European Working Group on Sarcopenia in Older People, the screening method studied showed a sarcopenia diagnosis accuracy index of 53%, that is, using this method eliminated rather than confirming the diagnosis of sarcopenia. Due to the low level of the sarcopenia diagnosis accuracy index for the screening method under investigation, at the second stage of the study, an attempt was made to develop a highly sensitive and specific screening method for sarcopenia in haemodialysis patients. In the course of the study, a screening method for «Screening of sarcopenia haemodialysis patients» sarcopenia was formed. This method includes two questions asked to the patient, anamnestic data (hemodialysis therapy experience), as well as two laboratory indicators (level of prealbumin and serum C-reactive protein), where each indicator has a score from 0 to 2. As a result of screening, the patient can score a maximum of 10 points. A total score of more than 5 indicates a high risk of sarcopenia in this patient. When diagnosing sarcopenia according to the recommendations of the European Working Group on Sarcopenia in Older People, the developed method demonstrated a sensitivity of 89% with a specificity of 73,5%, the overall accuracy index was 77%.
