We analyzed dispensing receipt data in the medical treatment in October 2019 using the Receipt Information/Specific Medical Examination Information National Database (NDB), extracted the cases of multiple combinations of Kampo prescriptions, and analyzed their frequencies. Of the 536,524 receipts, 44,731 (8.3%) included Kampo and non-Kampo crude drug preparations. Of the receipts that included Kampo and non-Kampo crude drug preparations, 38,032 receipts (7.1%) included single Kampo or non-Kampo crude drug preparation. There were 6,699 receipts (1.2%) that included multiple Kampo and non-Kampo crude drug preparations. There were 187 receipts for the decoctions containing multiple rude drugs without Kampo preparations, and the ratio was 0.035% of all receipts and 0.42% of the receipts containing Kampo and non-Kampo crude drug preparations. There was one receipt containing eight Kampo preparations, three receipts containing seven Kampo preparations, and a total of 84 receipts containing five or more Kampo preparations. Although it is unclear how many multiple Kampo preparations were prescribed at the same time, this investigation indicates the actual duplication of multiple Kampo preparations.
