Patient characteristics contribute to progression from acute opioid use to COU, but most are not clinically modifiable. To develop and validate machine-learning algorithms that use claims data to predict progression from acute to COU in the Medicaid population, adult opioid na\u00efve Medicaid patients from 6 anonymized states who received an opioid prescription between 2015 and 2019 were included. Five machine learning (ML) Models were developed, and model performance assessed by area under the receiver operating characteristic curve (auROC), precision and recall. In the study, 29.9% (53820\/180000) of patients transitioned from acute opioid use to COU. Initial opioid prescriptions in COU patients had increased morphine milligram equivalents (MME) (33.2 vs. 23.2), tablets per prescription (45.6 vs. 36.54), longer prescriptions (26.63 vs 24.69 days), and higher proportions of tramadol (16.06% vs. 13.44%) and long acting oxycodone (0.24% vs 0.04%) compared to non- COU patients. The top performing model was XGBoost that achieved average precision of 0.87 and auROC of 0.63 in testing and 0.55 and 0.69 in validation, respectively. Top-ranking prescription-related features in the model included quantity of tablets per prescription, prescription length, and emergency department claims. In this study, the Medicaid population, opioid prescriptions with increased tablet quantity and days supply predict increased risk of progression from acute to COU in opioid-na\u00efve patients. Future research should evaluate the effects of modifying these risk factors on COU incidence.<\/jats:p>","DOI":"10.1371\/journal.pdig.0000075","type":"journal-article","created":{"date-parts":[[2022,8,25]],"date-time":"2022-08-25T17:29:57Z","timestamp":1661448597000},"page":"e0000075","update-policy":"https:\/\/doi.org\/10.1371\/journal.pdig.corrections_policy","source":"Crossref","is-referenced-by-count":6,"title":["Prescription quantity and duration predict progression from acute to chronic opioid use in opioid-na\u00efve Medicaid patients"],"prefix":"10.1371","volume":"1","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9466-880X","authenticated-orcid":true,"given":"Drake G.","family":"Johnson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5570-0536","authenticated-orcid":true,"given":"Vy Thuy","family":"Ho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9739-3968","authenticated-orcid":true,"given":"Jennifer M.","family":"Hah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith","family":"Humphreys","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4777-4834","authenticated-orcid":true,"given":"Ian","family":"Carroll","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Curtin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven M.","family":"Asch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6553-3455","authenticated-orcid":true,"given":"Tina","family":"Hernandez-Boussard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,8,25]]},"reference":[{"key":"pdig.0000075.ref001","first-page":"e201318","article-title":"Drug overdose deaths head toward record number in 2020, CDC warns.","author":"J.
