Abstract [en]

This paper analyzes the cost-effectiveness, measured in cost per quality-adjusted life year (QALY), of the surgical method Gastric Bypass as a treatment for obesity in comparison to not performing Gastric bypass. Data was obtained from the hospital in Värmland (Torsby), Sweden, that performs Gastric bypass surgery on severely obese individuals and from literature studies.A decision-tree analysis was conducted identifying probabilities, costs and utilities with the treatment and non-treatment alternative. The incremental cost-effectiveness ratio (ICER) for the base case resulted in -19 562 951 SEK per QALY, i.e. the treatment is cost-saving and produces more QALYs than no surgical treatment. A sensitivity analysis was performed with Monte Carlo simulation of 5 000 cases. Given the assumptions made in this study the simulation resulted in all the ICERs being cost saving. In summary, Gastric bypass was shown to be very economically efficient, leading to cost-savings as well as improved health.
