ObjectiveTo undertake a cost-effectiveness analysis comparing conservative management, surgery and radiosurgery for treating small-to-medium (1-20 mm)-sized vestibular schwannomas.DesignModel-based economic evaluation using individual-level data from a Birmingham-based longitudinal patient database and from published sources. Both a decision tree and state-transition (Markov) model were developed, from an National Health Service (NHS) perspective. Sensitivity analyses were also carried out.SettingSecondary care treatment for patients with small-to-medium-sized vestibular schwannomas.ParticipantsThree hypothetical cohorts of adult patients receiving conservative management, radiosurgery or surgery treatment, aged 58 years as starting age within model.Main Outcome MeasuresCost-effectiveness based on cost per quality-adjusted life year (QALY).ResultsConservative management is the preferred strategy for the treatment of small-to-medium-sized vestibular schwannomas. Conservative management is both cheaper (-£ 722 and -£ 2764) and more effective (0.136 and 0.554 quality-adjusted life years) than both radiosurgery and surgery, respectively. A conservative strategy can therefore be considered as highly cost-effective. This result is sensitive to the assumed quality-of-life parameters in the model. Sensitivity analysis suggests that the probability of a conservative strategy being the most cost-effective approach compared with surgery and radiosurgery at a willingness to pay of £ 20 000/quality-adjusted life year gained is 80% and 55%, respectively.ConclusionsA conservative approach is the preferred strategy for treatment of small-to-medium vestibular schwannomas. This result is sensitive to quality-of-life values used in the analysis. More research is required to assess the impact of treatment upon patients' health-related quality of life over time.© 2013 John Wiley & Sons Ltd.
