Mumtaz K et al. Validation of risk score in predicting early readmissions in decompensated cirrhotic patients: a model based on the administrative database. Hepatology. 2019;70:630-639. DOI: 10.1002/hep.30274. PMID: 30218583. Table 3A points, range -11 to +49: age 18-39 years +7, 40-64 years +4, 65 years or older 0; Medicare +4, Medicaid +5, private insurance 0, self-pay -3, no charge or other -1; Elixhauser comorbidity index 3 or higher +2; nonalcoholic etiology +2; ascites +5; hepatic encephalopathy +4; variceal bleeding -7; hepatocellular carcinoma +3; paracentesis +4; hemodialysis +7; routine disposition 0, transfer -1, home health +1, left against medical advice +10. Low risk is under 20% (scores -11 through 6, 9.3% of the cohort), medium risk is 20% to 30% (scores 7 through 17, 61.3%), and high risk is over 30% (scores 18 through 49, 29.5%). Table 3B gives the narrower ranges shown on the result line. The published example is age 35 years, Medicaid, alcoholic etiology, Elixhauser index at least 3, ascites, paracentesis, and routine discharge, totaling 23, with an estimated 36% 30-day readmission risk. That 36% figure is the narrative for this one example. Table 3B places scores 23 through 26 in the range over 35% to 40%. c-statistic 0.6. (2019)
