Participants completed a questionnaire on their demographic characteristics, knowledge and attitudes toward opioid therapy, and barriers to accessing opioids for cancer pain. <\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p> Two hundred seven HCPs and 15 policymakers\/regulators completed the questionnaire. Poor knowledge about opioids in cancer pain was found in 63.3% of HCPs and 80.0% of policymakers\/regulators. Poor knowledge was associated with a lack of training in cancer pain management or palliative care (PC; prevalence ratio [PR], 1.14 [95% CI, 1.04 to 1.24]). Negative attitudes toward opioid therapy in cancer pain were held by 64.7% of HCPs and 80.0% of policymakers\/regulators. Negative attitudes were associated with the unavailability of oral morphine in the workplace (PR, 1.10 [95% CI, 1.01 to 1.20]). The most common major barriers reported were the absence of national policy on pain management and PC (34.7%), inadequate training in opioid use for cancer pain (33.8%), lockdown of health facilities during the COVID-19 pandemic (32.4%), limited opioid availability in local health facilities (32.4%), and excessively restrictive regulation of opioid dispensing in pharmacies (32.4%). <\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p> This study found a knowledge deficit and negative attitudes toward opioid therapy for cancer pain among HCPs and policymakers\/regulators. Improving education and training in opioid therapy is essential. Recognizing major barriers can guide strategies to enhance safe opioid accessibility for cancer pain management in Vietnam. <\/jats:p><\/jats:sec>","DOI":"10.1200\/go.23.00463","type":"journal-article","created":{"date-parts":[[2024,5,9]],"date-time":"2024-05-09T19:59:27Z","timestamp":1715284767000},"update-policy":"https:\/\/doi.org\/10.1200\/crossmark","source":"Crossref","is-referenced-by-count":2,"title":["Opioid Therapy for Cancer Pain in Vietnam: Knowledge, Attitudes, and Perceived Barriers Among Health Care Professionals, Policymakers, and Regulators"],"prefix":"10.1200","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2805-541X","authenticated-orcid":true,"given":"Trang","family":"Nguyen","sequence":"first","affiliation":[{"name":"Department of Pharmacy, University Medical Center Ho Chi Minh City, Ho Chi Minh City, Vietnam"},{"name":"College of Nursing and Health Sciences, Flinders University, Adelaide, South Australia, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anh","family":"Dam","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, National Geriatric Hospital, Ha Noi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-1872-5981","authenticated-orcid":true,"given":"Duong","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Children's Hospital 1, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phuong","family":"Tran","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, University of Medicine and Pharmacy at Ho Chi Minh City, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4591-1812","authenticated-orcid":true,"given":"Nguyen L.T.","family":"Truong","sequence":"additional","affiliation":[{"name":"Section for Outcome Research, Center for Medical Data Science, Medical University of Vienna, Vienna, Austria"},{"name":"Pharmacy Department, School of Medicine, Vietnam National University-Ho Chi Minh City, Binh Duong, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, University Medical Center Ho Chi Minh City, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3048-9180","authenticated-orcid":true,"given":"Duong","family":"Le","sequence":"additional","affiliation":[{"name":"Department of Palliative Care, University of Medicine and Pharmacy at Ho Chi Minh City, Ho Chi Minh City, Vietnam"},{"name":"Department of Geriatrics and Palliative Care, University Medical Center Ho Chi Minh City, Ho Chi Minh City, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5655-3884","authenticated-orcid":true,"given":"Linh","family":"Bui","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Harvard T.H.
