623: Changes in Pain Management Practice Five Months After a Seminar on Cancer Survivors� Chronic Pain

Topic: Education, Societal Impact, and Others
Subtopic: Education of pain care

Background and Aims: In 2023, the Japan Society of Pain Clinicians (JSPC) published a consensus statement on the treatment of chronic pain in cancer survivors. The statement is currently available in Japanese on the JSPC website, with an English version published in 2025.
To promote understanding of this statement, the JSPC conducted a series of eight online seminars from October 2024 to May 2025. The seminar program received an educational grant from Pfizer Pharmaceuticals. Five months after the seminar, we conducted a follow-up survey to evaluate whether participants had experienced changes in their clinical practice.

Methods: The study population comprised 238 healthcare professionals involved in palliative care who attended the seminar on chronic pain in cancer survivors.
Five months after the seminar, all participants were invited to complete an email-based questionnaire about their management of chronic pain in cancer survivors and any changes in their clinical practice.

Results: A total of 110 participants responded to the survey (response rate: 46.2%). Participants were physicians (72%), nurses (13%), pharmacists (9%), and others (6%). After the seminar, 88.2% involved prescribing opioids for cancer-related pain; 11.8% did not. After the seminar, 66.4% involved prescribing opioids for non-cancer chronic pain; 33.6% did not. After the seminar, 89% read and understood the statement, 14% read but did not recall it clearly, and 7% had not read it. Since the seminar, 12.7% reported major changes, 52.7% showed slight changes, and 34.5% no change in their treatment approach for cancer survivors .

Conclusions: JSPC conducted an online seminar series on chronic pain in cancer survivors from October 2024 to May 2025. More than 65% of participants reported changes in their clinical approach to managing chronic pain in cancer survivors five months after attending the seminar, suggesting that structured educational programs may influence clinical practice.
