This study evaluated the construct validity of a high-frequency, low-burden \u201cGlobal Postoperative Status\u201d item as an exploratory measure of concurrent early post-discharge recovery burden.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Prospective observational cohort study of 257 patients undergoing surgery for lumbar disc herniation or spinal canal stenosis who contributed 1627 postoperative status assessments over 6 weeks via secure mobile surveys every 2-3 days. Construct validity was examined through associations with pain-peak frequency, pain-peak intensity (0-10), analgesic use, and wound pain. Because peak intensity was conditionally collected only when pain peaks were reported, the primary mixed-effects complete-case model included 209\/1627 assessments (82 subjects); broader sensitivity analyses used larger available-case datasets.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Worse Global Status scores were consistently associated with greater concurrent pain burden. Median status was 60 (IQR 50-80) when no pain peaks were reported vs 40 (IQR 20-50) when pain peaks occurred >5\/day. Mean status was 67.2 without analgesics and 41.9 with combined opioid plus non-opioid analgesics. Status correlated inversely with pain peak intensity (Spearman rho = \u22120.53,\n P<\/jats:italic>\n < 0.001). In the exploratory complete-case mixed-effects model, each 1-point increase in pain peak intensity was associated with a 4.53-point lower status score (95% CI -6.09 to \u22122.97;\n P<\/jats:italic>\n < 0.001); this direction was preserved in broader sensitivity analyses that retained more observations.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The high-frequency Global Status item showed exploratory construct-validity evidence as a low-burden indicator of concurrent postoperative pain burden and analgesic use after lumbar spine surgery. The findings do not establish responsiveness, test-retest reliability, criterion validity against established PROMs, or decision-support utility, and prospective validation studies are required before clinical implementation claims can be made.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/21925682261449153","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T14:18:08Z","timestamp":1780669088000},"page":"3938-3950","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["High-Frequency Global Postoperative Status PROMs Track Pain Peaks and Analgesic Use After Degenerative Lumbar Spine Surgery"],"prefix":"10.1177","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3842-0783","authenticated-orcid":false,"given":"Pavlina","family":"Lenga","sequence":"first","affiliation":[{"name":"Heidelberg University Hospital"},{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Fleige","sequence":"additional","affiliation":[{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Max Christian","family":"Blumenstock","sequence":"additional","affiliation":[{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2716-5425","authenticated-orcid":false,"given":"Matthias","family":"Ganzinger","sequence":"additional","affiliation":[{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Ille","sequence":"additional","affiliation":[{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandro M.","family":"Krieg","sequence":"additional","affiliation":[{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Dugas","sequence":"additional","affiliation":[{"name":"Heidelberg University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"e_1_3_9_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2024.04.019"},{"key":"e_1_3_9_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpain.2010.07.001"},{"key":"e_1_3_9_4_2","doi-asserted-by":"publisher","DOI":"10.1101\/2025.09.27.25336802"},{"key":"e_1_3_9_5_2","doi-asserted-by":"publisher","DOI":"10.3171\/2022.12.SPINE221302"},{"key":"e_1_3_9_6_2","doi-asserted-by":"publisher","DOI":"10.2196\/16480"},{"key":"e_1_3_9_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-023-04941-8"},{"key":"e_1_3_9_8_2","doi-asserted-by":"publisher","DOI":"10.1023\/B:QURE.0000018499.64574.1f"},{"key":"e_1_3_9_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2025.05.017"},{"key":"e_1_3_9_10_2","doi-asserted-by":"publisher","DOI":"10.1227\/neu.0000000000002245"},{"key":"e_1_3_9_11_2","doi-asserted-by":"publisher","DOI":"10.1227\/neu.0000000000002911"},{"key":"e_1_3_9_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/AJP.0000000000000072"},{"key":"e_1_3_9_13_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.OA.20.00122"},{"key":"e_1_3_9_14_2","doi-asserted-by":"publisher","DOI":"10.3171\/2023.2.SPINE23136"},{"key":"e_1_3_9_15_2","doi-asserted-by":"publisher","DOI":"10.3171\/2021.2.SPINE202181"},{"key":"e_1_3_9_16_2","doi-asserted-by":"publisher","DOI":"10.14245\/ns.2550410.205"}],"container-title":["Global Spine Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/21925682261449153","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/21925682261449153","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/21925682261449153","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,11,3]],"date-time":"2026-11-03T03:29:48Z","timestamp":1793676588000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/21925682261449153"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,5]]},"references-count":15,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,11]]}},"alternative-id":["10.1177\/21925682261449153"],"URL":"https:\/\/doi.org\/10.1177\/21925682261449153","relation":{},"ISSN":["2192-5682","2192-5690"],"issn-type":[{"value":"2192-5682","type":"print"},{"value":"2192-5690","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,5]]}}}
