Abstract:

BACKGROUND: Patients with cirrhosis are at high risk for hepatocellular carcinoma (HCC), but few undergo guideline-recommended semi-annual screening. Randomized clinical trials (RCTs) demonstrate that mailed outreach can increase screening versus visit-based screening. We estimated the costs and cost-effectiveness of an outreach strategy versus usual care. METHODS: We built a 10-year Markov chain Monte Carlo microsimulation model to conduct a cost-effectiveness analysis comparing a mailed outreach program versus usual care for HCC screening in a cohort of 10,000 patients with cirrhosis. Model inputs were based on literature review (2005-current), and costs were based on inflation-adjusted estimates from Surveillance, Epidemiology, and End Results (SEER)-Medicare claims data. We conducted one-way sensitivity analyses for HCC incidence, outreach costs, efficacy of the outreach strategy to increase screening, and efficacy of curative (versus palliative) HCC treatments. FINDINGS: Mailed outreach was estimated to cost $32.45 per patient in the first year and $21.90 per patient in subsequent years. The outreach program increased the number of HCC patients detected at an early stage by 48.4% and increased quality-adjusted life years (QALYs) by 300. Cost savings from these increases offset the costs of mailed outreach. Mailed outreach remained cost-effective across a wide range of HCC incidence rates, outreach costs, efficacy of the outreach strategy to increase screening, and the efficacy of curative HCC treatments. Annual out-of-pocket patient costs in the outreach arm were low at $13 per year. INTERPRETATION: Mailed outreach to encourage HCC screening in patients with cirrhosis dominates usual care and should be considered for implementation in routine practice.
