Cost-effectiveness of terlipressin for hepatorenal syndrome: The United States hospital perspective
Background
Hepatorenal syndrome (HRS) is characterized by severely reduced renal perfusion that precipitates rapid morbidity and mortality. Terlipressin is the only US Food and Drug Administration-approved treatment to improve kidney function for adults with HRS with a rapid reduction in kidney function. Prior to the approval of terlipressin, unapproved vasoconstrictive agents used in HRS treatment were octreotide/midodrine and norepinephrine with albumin.
Methods
A cohort decision-tree model representing a US hospital perspective, assessed the clinical outcomes and direct medical costs (based primarily on hospital charges) of treating HRS with terlipressin + albumin (ALB) versus midodrine/octreotide (MID/OCT)+ ALB, or norepinephrine (NorEp)+ALB. Treatment efficacy was defined by clinical response (complete/HRS reversal, partial, or no response) based on change of serum creatinine derived from published clinical trial reports. The proportions of patients with complete response were: terlipressin + ALB (36.2%), NorEp + ALB (19.1%), and MID/OCT + ALB (3.1%). Model outcomes included utilization of HRS-related healthcare resources (hospital and intensive care, outpatient and emergency department, dialysis, and transplantations), adverse events, and HRS-related mortality. Outcomes were assessed for the initial hospitalization in the base case and at 30, 60, and 90 days post discharge.
Results
Total costs incurred over the initial hospitalization with terlipressin + ALB were lower vs NorEp + ALB primarily due to higher ICU costs with NorEp + ALB ($7,433 vs $61,897). TER + ALB was associated with higher total costs vs MID/OCT + ALB due to higher pharmacy costs with terlipressin + ALB. The cost per complete response achieved of terlipressin + ALB ($451,605) was half that of NorEp + ALB ($930,571) and one-tenth that of MID/OCT + ALB ($4,942,123).
Conclusions
HRS patients treated with terlipressin experienced better clinical outcomes and a lower cost per treatment response vs alternative treatments. ICU days and pharmacy costs were key cost drivers distinguishing the treatment groups. These outcomes suggest that terlipressin is cost-effective on the basis of total cost per response achieved
