Objective To identify the Brazilian dialysis centers that assess sarcopenia in their clinical routine and how it is diagnosed and managed. Methods This is a web-based survey study, structured with quali-quantitative questions about how sarcopenia is routinely assessed in dialysis centers. Centers officially registered at the Brazilian Society of Nephrology website were contacted through e-mail and/or telephone. The survey included questions about the dialysis staff, instruments, methods, and criteria for diagnosing sarcopenia, and how it was managed if diagnosed. Results Sixty-two dialysis centers responded to the survey and 23 (37%) assessed sarcopenia as a clinical routine. Of these, 13 had an exercise professional (57%), and all had a dietitian. The main consensus adopted to diagnose sarcopenia was the revised European Working Group on Sarcopenia in Older People (EWGSOP2; n=10, 44%). The assessment frequency was mainly six-monthly and quarterly (n=8, 35% both). The most common methods to assess sarcopenia traits were handgrip strength (n=16, 70%) for physical function and bioimpedance analysis (n=15, 65%) for muscle mass. Centers with an exercise professional had a higher chance of assessing sarcopenia (OR=4.23, 95% CI: 1.37 to 13.07). Changes in the dietary plan (n=20, 87%) and prescription of resistance and combined exercises (n=8, 35% both) were the most adopted intervention strategies. Conclusion The assessment of sarcopenia and its traits in Brazilian dialysis centers as a clinical routine was low. The most used definition guideline was the EWGSOP2, while the most used assessments were handgrip strength and bioimpedance analysis.
