Obesity Surgery Mortality Risk Score (OS-MRS)
Validated risk score predicting 90-day mortality following bariatric surgery. Five risk factors: BMI above 50, male sex, hypertension, known risk factors for pulmonary embolism, and age above 45 years. Score 0-5; class A (0-1) = low risk (0.31% mortality); class B (2-3) = intermediate (1.9%); class C (4-5) = high risk (7.56%). From DeMaria et al. 2007.
