BackgroundRotavirus (RV) causes a highly contagious gastroenteritis especially in children under five years of age. Since 2006 two RV-vaccines are available in Europe (Rotarix(®) and RotaTeq(®)). To support informed decision-making within the German Standing Committee on Vaccination (STIKO) the cost-effectiveness of these two vaccines was evaluated for the German healthcare setting.MethodsA Markov model was developed to evaluate the cost-effectiveness from the statutory health insurance (SHI) and from the societal perspective. RV-cases prevented, RV-associated hospitalizations avoided, and quality-adjusted life years (QALY) gained were considered as health outcomes. RV-incidences were calculated based on data from the national mandatory disease reporting system. RV-vaccine efficacy was determined as pooled estimates based on data from randomized controlled trials. Vaccine list prices and price catalogues were used for cost-assessment. Effects and costs were discounted with an annual discount rate of 3%.ResultsThe base-case analysis (SHI-perspective) resulted in an incremental cost-effectiveness and cost-utility ratio for Rotarix(®) of € 184 per RV-case prevented, € 2457 per RV-associated hospitalization avoided, and € 116,973 per QALY gained. For RotaTeq(®), the results were € 234 per RV-case prevented, € 2622 per RV-associated hospitalization avoided, and € 142,732 per QALY gained. Variation of various parameters in sensitivity analyses showed effects on the ICERs without changing the overall trend of base-case results. When applying base-case results to the 2012 birthcohort in Germany with 80% vaccination coverage, an estimated 206,000-242,000 RV-cases and 18,000 RV-associated hospitalizations can be prevented in this birthcohort over five years for an incremental cost of 44.5-48.2 million €.ConclusionOur analyses demonstrate that routine RV-vaccination could prevent a substantial number of RV-cases and hospitalizations in the German healthcare system, but the saved treatment costs are counteracted by costs for vaccination. However, with vaccine prices reduced by ∼62-66%, RV-vaccination could even become a cost-saving preventive measure.Copyright © 2014 Elsevier Ltd. All rights reserved.
