There is a lack of health economics evidence on the use of fecal microbiota transplantation (FMT) for inflammatory bowel disease (IBD). This study aims to evaluate the cost-effectiveness before (with conventional therapy) and after introducing FMT for treating IBD. 104 patients with IBD received FMT were recruited. Health status was evaluated by European dimension health table (ED-5Q). Incremental cost-effectiveness ratio (ICER) and net monetary benefit (NB) were calculated by different age groups, genders, smoking status, and disease subtypes. The willingness-to-pay threshold was set to the value equal to three times China’s per capita GDP (141240 CNY/QALY, 2014). From the health-care perspective, FMT strategy was 73% likely to be cost-effective compared with the conventional therapy before FMT with an ICER of -185712 CNY/QALY and a positive NB of CNY 45150. From the societal perspective, FMT strategy was 75% likely to be cost-effective with an ICER of -207417 CNY/QALY and a positive NB of CNY 48395. Moreover, younger patients (≤ 24), females, non-smokers and Crohn’s disease (CD) achieved more benefits. This study for the first time demonstrated that FMT showed its cost-effectiveness, especially on improving the life quality and decreasing the medical and societal cost, for the moderate to severe IBD in a Chinese cohort.
