OBJECTIVES: The purpose of this study was to estimate short-term medical cost savings, including costs not directly associated with Smoking Cessation Outpatient Visits (SCOVs), from claims data of employee based public health insurance in Japan. METHODS: We conducted two analyses using claims data from January 2005 to December 2013 provided by Japan Medical Data Center Co., Ltd. In the first analysis, we compared medical costs composed of inpatient, outpatient, and medications of the SCOV group, smokers having SCOVs, with those of non-SCOV group for each year. The first day of index year 0 is the day of first SCOV for the SCOV group and is the day after one observation year for the non-SCOV group. In the second analysis, among smokers with SCOVs, a mean increase ratio of medical costs was calculated, varying by the number of SCOVs. RESULTS: In the first analysis, medical costs per patient per years (PPPYs) of the SCOV group were ¥95,200 at year -1, ¥173,400 at year 0, ¥130,900 at year 1 and ¥116,100 at year 5, and PPPYs of non-SCOV group were ¥95,200 at year -1, ¥100,700 at year 0, ¥108,100 at year 1 and ¥125,900 at year 5. The PPPY of SCOV group at year 0 was higher than that of non-SCOV group at year 0 but the relation was reversed at year 5. In the second analysis, the mean increase ratio of medical costs of the one-SCOV group was the highest, 58%, and that of five-SCOV group was the smallest, 34%. This measure showed a downward trend. CONCLUSIONS: Results are suggestive of a possibility that the future medical costs of patients with smoking cessation outpatient visits are lower than those without smoking cessation outpatient visit and increasing the number of smoking cessation outpatient visits decreases the mean increase ratios of medical costs.
