Epidural steroid injection (ESI) is a widely used procedure for managing lower back pain. This study investigated the association of preprocedural frailty status with the efficacy of ESI in elderly patients diagnosed with degenerative lumbar spinal diseases.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> This retrospective observational study included patients aged 65 years and older who underwent lumbar ESI. Frailty status (robust, prefrail, and frail) assessed via the Frailty Phenotype Questionnaire was collected along with demographic and clinical parameters. Good analgesia was defined as a \u2265\u200950% reduction in pain score at 4\u2010week follow\u2010up evaluation. Multivariable logistic regression analyses were performed to identify factors associated with poor analgesia.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> We included 289 patients in this study. Frailty status correlated with analgesic outcomes, with worsening frailty status correlating with increasingly poor analgesia after the injection (robust\u2009=\u200934.5%, prefrail\u2009=\u200940.8%, and frail\u2009=\u200960.0%, <jats:italic>p<\/jats:italic> = 0.003), predominantly in female patients. After adjusting for demographic and clinical factors, frail patients demonstrated much higher odds of poor analgesia than robust individuals (adjusted odds ratio [aOR]\u2009=\u20092.673, 95% confidence interval [CI]\u2009=\u20091.338\u20135.342, <jats:italic>p<\/jats:italic> = 0.005). Conversely, prefrail patients did not show a significant association with analgesic outcome (aOR\u2009=\u20091.293, 95% CI\u2009=\u20090.736\u20132.272, <jats:italic>p<\/jats:italic> = 0.372).<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Frailty, but not prefrailty, appeared to be an independent factor associated with poor analgesic efficacy of ESI in elderly patients with symptomatic degenerative lumbar spinal disease receiving conservative care.<\/jats:p>","DOI":"10.1155\/2024\/5038496","type":"journal-article","created":{"date-parts":[[2024,9,7]],"date-time":"2024-09-07T13:34:00Z","timestamp":1725716040000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Influence of Frailty Status on the Efficacy of Epidural Steroid Injections in Elderly Patients With Degenerative Lumbar Spinal Disease"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2143-3943","authenticated-orcid":false,"given":"Hee Jung","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2497-2356","authenticated-orcid":false,"given":"Ho Jae","family":"Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4058-7697","authenticated-orcid":false,"given":"Shin Hyung","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,9,7]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph20010670"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.brs.0000206367.57918.3c"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2007.087296"},{"key":"e_1_2_11_4_2","first-page":"S27","article-title":"Epidural Interventions in the Management of Chronic Spinal Pain: American Society of Interventional Pain Physicians (ASIPP) Comprehensive Evidence-Based Guidelines","volume":"24","author":"Manchikanti L.","year":"2021","journal-title":"Pain Physician"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.3344\/kjp.2019.32.3.178"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2014.04.003"},{"key":"e_1_2_11_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmrj.2011.07.020"},{"key":"e_1_2_11_8_2","first-page":"E1105","article-title":"Influence of Handgrip Strength and Psoas Muscle Index on Analgesic Efficacy of Epidural Steroid Injection in Patients With Degenerative Lumbar Spinal Disease","volume":"25","author":"Kim S.
