The Committee on Safety of the Japan Society of Pain Clinicians (JSPC) has investigated the adverse events (AEs), which are categorized from level 0 to 5 according to the severity by “the incident severity classification system recommended by the National University Hospital Council of Japan” in pain-related management of all Japanese board-certificated training facilities since 2009. By referring to this classification system, it is mandatory to report AEs of 3a or above and more detailed reports are requested for AEs of 3b or above. Here we report AEs and facility information in 2019 and 2020. In this survey, we received responses from 98% of the facilities in both years. There were 8 cases of 3b or above AEs in 2019 and 7 cases in 2020 related to analgesics/additives, and 64 cases in 2019 and 52 cases in 2020 related to nerve block/interventional therapy. It is necessary to share the results among the members of the JSPC and enhance the recognition of risk management in pain treatment settings.
