Data from five hospitals were retrospectively analyzed, encompassing patients who underwent 10 distinct surgical procedures. Numeric rating scale scores were used to assess the worst postoperative pain intensity during the 24 h after surgery. The multivariate linear regression model analyzed the relationship between age and pain intensity. Subgroup analyses were performed according to sex and patient-controlled analgesia (PCA). This study included 41,187 patients. Among the surgeries studied, lumbar spine fusion (\u03b2 = \u22120.155, p &lt; 0.001) consistently and significantly exhibited a decrease in worst postoperative pain with increasing age. Similar trends were observed in cholecystectomy (\u03b2 = \u22120.029, p &lt; 0.001) and several other surgeries; however, the results were inconsistent across all analyses. Surgeries with higher percentages of PCA administration had lower median worst-pain scores. In conclusion, age may affect postoperative pain intensity after specific surgeries; however, a comprehensive understanding of the complex interplay between age, surgical intervention, and pain intensity is required. Pain management strategies should consider various factors, including age-related variations.<\/jats:p>","DOI":"10.3390\/jcm12185912","type":"journal-article","created":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T03:54:06Z","timestamp":1694490846000},"page":"5912","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Age-Related Variations in Postoperative Pain Intensity across 10 Surgical Procedures: A Retrospective Study of Five Hospitals in South Korea"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3818-2239","authenticated-orcid":false,"given":"Jong-Ho","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon-si 24253, Republic of Korea"},{"name":"Institute of New Frontier Research Team, Hallym University College of Medicine, Chuncheon-si 24252, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2656-9222","authenticated-orcid":false,"given":"Jong-Hee","family":"Sohn","sequence":"additional","affiliation":[{"name":"Institute of New Frontier Research Team, Hallym University College of Medicine, Chuncheon-si 24252, Republic of Korea"},{"name":"Department of Neurology, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae-Jun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon-si 24253, Republic of Korea"},{"name":"Institute of New Frontier Research Team, Hallym University College of Medicine, Chuncheon-si 24252, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7753-8464","authenticated-orcid":false,"given":"Young-Suk","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon-si 24253, Republic of Korea"},{"name":"Institute of New Frontier Research Team, Hallym University College of Medicine, Chuncheon-si 24252, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1976","DOI":"10.1097\/j.pain.0000000000001939","article-title":"The revised International Association for the Study of Pain definition of pain: Concepts, challenges, and compromises","volume":"161","author":"Raja","year":"2020","journal-title":"Pain"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"934","DOI":"10.1097\/ALN.0b013e31828866b3","article-title":"Pain Intensity on the First Day after Surgery: A Prospective Cohort Study Comparing 179 Surgical Procedures","volume":"118","author":"Gerbershagen","year":"2013","journal-title":"Anesthesiology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1016\/S0885-3924(00)00174-3","article-title":"Assessment of Pain Experiences after Elective Surgery","volume":"20","author":"Svensson","year":"2000","journal-title":"J.
