Diagnostic approach and management strategy for patients with exertional rhabdomyolysis – Results from an international survey of healthcare professionals

BackgroundRhabdomyolysis is a complex and potentially life-threatening syndrome characterized by the rapid breakdown of damaged skeletal muscle. Despite its clinical significance, universally accepted diagnostic criteria and standardized management guidelines are lacking.MethodsA cross-sectional online survey about the current diagnostic approach, assessment of risk factors and severity, and management of follow-up of rhabdomyolysis was conducted among clinicians across Europe, Australia, and the USA.ResultsFifty-four respondents from 16 countries completed the survey. Results revealed considerable variability in hospital admission practices, and patient follow-up. Some agreement was found in the frequent use of genetic and neurophysiological testing in as diagnostic tools. The survey revealed no consensus on which CK-level would be considered cut-off levels for rhabdomyolysis.ConclusionsThe survey found little to no coherent approach to diagnosing, assessment of severity, nor follow-up of rhabdomyolysis among respondents who were primarily neurologists and pediatric neurologists. It highlights the need for international guidelines in the diagnostic process, treatment and follow-up of rhabdomyolysis as well as a universally agreed definition of rhabdomyolysis.
