McMahon_Score_for_Rhabdomyolysis v.1
McMahon Score for Rhabdomyolysis predicts mortality or acute kidney injury (AKI) in rhabdomyolysis patients.
To predict mortality or acute kidney injury (AKI) in rhabdomyolysis patients.
Use in patients ≥18 years old with rhabdomyolysis (CPK >5,000 U/L within 72 hours of admission). The score is calculated based on 8 paramters: age, sex, initial creatinine, initial calcium, initial CPK, initial phosphate, initial bicarbonate and Rhabdo secondary to seizures, syncope, exercise, statins, or myositis. Interpretation: McMahon Score Risk group Recommendation <6 Low risk Usual care (3% risk of death or AKI requiring RRT) ≥6* Not low risk Initiate renal protective therapy including high-volume fluid resuscitation to urine output 1-2 mL/kg/hr (52% risk of death or AKI requiring RRT at scores ≥10)
Do not use in patients with pre-existing end-stage renal disease or with elevated CPK due to MI.
