Abstract
BackgroundPhotodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) showed improvement of diagnostic accuracy and treatment efficacy compared to white light TURBT (WL-TURBT). While PDD-TURBT is highly effective, PDD-TURBT requires the use of PDD device and light-sensitive substance precursor, which increases the medical cost compared to WL-TURBT. In this study, the impact on health care economic costs were examined between PDD-TURBT and WL-TURBT. MethodsOf the total 265 patients, 88 patients for WL-TURBT and 105 patients for PDD-TURBT were available for analysis. Costs were also examined between 34 patients without false-positives and 36 patients with false-positives with a follow-up period of at least 200 days. To compare costs between the two treatments, we calculated the cost/person/year of TURBT using Japanese Diagnosis Procedure Combination and Per-Diem Payment System (DPC/PDPS). ResultsThe total number of surgeries including the first TURBT was 135 (47 recurrences) in the WL-TURBT group and 133 (28 recurrences) in the PDD-TURBT group. The cost per person for hospitalization and surgery was 366,310 Japanese yen (JPY) for the WL-TURBT and 501,930 JPY for the PDD-TURBT. The cost per person per year was 491,622 JPY in the WL-TURBT group and 506,405 JPY in the PDD-TURBT group. Regarding false-positives, the cost per person per year was 494,544 JPY in the group without false-positives and 328,086 JPY in the group with false-positives. ConclusionsAlthough PDD-TURBT is cost more than WL-TURBT for one surgical hospitalization, the cost per person per year for PDD-TURBT and WL-TURBT is cost-neutral.
