mumtaz_cirrhosis_readmission_score: Mumtaz Score for Readmission in Cirrhosis

Description

Calculates the Mumtaz Score to predict the 30-day readmission risk in patients with decompensated cirrhosis. The score uses variables from the index admission, including demographics, comorbidities (Elixhauser), etiology, complications (ascites, HE, variceal bleed), procedures (paracentesis, dialysis), and discharge disposition.

Usage

mumtaz_cirrhosis_readmission_score(age, primary_payer, elixhauser_comorbidity_score,
                                   non_alcoholic_etiology, ascites_present,
                                   hepatic_encephalopathy_present,
                                   variceal_bleeding_present, hcc_present,
                                   paracentesis_performed, hemodialysis_performed,
                                   disposition)
