Primary inference focused on within-day patterns within each cohort. Between-cohort comparisons were descriptive. Exploratory correlation analyses and a medication-related mixed-effects sensitivity analysis incorporating scheduled strong opioid use were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>In the cancer-related pain cohort, the cohort-level pain profile remained relatively stable, with no significant time-of-day effect. The chronic noncancer pain cohort showed higher pain upon awakening and at bedtime and lower pain in the late morning. In the cancer-related pain cohort, higher 3-day mean pain intensity was associated with longer illness duration and higher Central Sensitization Inventory\u20139, Pain Catastrophizing Scale\u20134, and Patient Health Questionnaire\u20132 scores. The medication-related sensitivity analysis supported the within-cohort interpretation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Hospitalized patients with chronic cancer-related pain showed relatively stable cohort-level pain intensity under routine inpatient management. This stability should not be assumed to apply uniformly to individual patients. Inpatient pain ratings should be interpreted in relation to functional status, medication-related factors, treatment context, and inpatient conditions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10966218261473685","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T03:12:32Z","timestamp":1785813152000},"page":"1711-1717","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Within-Day Pain Profiles in Hospitalized Patients with Chronic Cancer-Related Pain: Implications for Inpatient Symptom Assessment"],"prefix":"10.1177","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-0880-2864","authenticated-orcid":false,"given":"Tatsuya","family":"Sugino","sequence":"first","affiliation":[{"name":"Department of Neurorehabilitation, Graduate School of Health Sciences, Kio University, Nara, Japan."},{"name":"Department of Rehabilitation, Suzuka Central General Hospital, Mie, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoichi","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Neurorehabilitation Research Center, Kio University, Nara, Japan."},{"name":"Department of Occupational Therapy, School of Rehabilitation, Hyogo Medical University, Hyogo, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu","family":"Morioka","sequence":"additional","affiliation":[{"name":"Department of Neurorehabilitation, Graduate School of Health Sciences, Kio University, Nara, Japan."},{"name":"Neurorehabilitation Research Center, Kio University, Nara, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"e_1_3_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpainsymman.2015.12.340"},{"key":"e_1_3_5_3_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2016.68.5206"},{"key":"e_1_3_5_4_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21453"},{"key":"e_1_3_5_5_1","first-page":"68","article-title":"The symptomatic treatment of incurable malignant disease","volume":"4","author":"Saunders C","year":"1964","unstructured":"4.Saunders C.
