In this study, we use the Pharmaceutical Benefits Scheme (PBS) dataset, which contains rich longitudinal dispensing data from Australian primary care and developed supervised models to predict successful deprescription. To overcome the challenge of observational administrative data, we developed two distinct annotation pathways (retrospective and prospective) to identify successful and unsuccessful deprescription cases and trained several supervised machine learning models using the labelled data from each pathway. The best accuracy in predicting successful deprescription was reached using XGBoost (0.81) and Random Forest (0.90) for retrospective and prospective annotation, respectively. The study results demonstrate the potential of administrative healthcare data for developing clinical decision support tools, though further validation against clinical outcomes is needed.<\/jats:p>","DOI":"10.3233\/shti250959","type":"book-chapter","created":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:36:22Z","timestamp":1754566582000},"source":"Crossref","is-referenced-by-count":0,"title":["Predicting Antidepressant Deprescription with Machine Learning Using Administrative Data"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2906-5732","authenticated-orcid":false,"given":"R A D L M K","family":"Ranwala","sequence":"first","affiliation":[{"name":"Quality Use of Medicines and Pharmacy Research Centre, Clinical Health Sciences, University of South Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6587-3169","authenticated-orcid":false,"given":"A.Q.","family":"Andrade","sequence":"additional","affiliation":[{"name":"Quality Use of Medicines and Pharmacy Research Centre, Clinical Health Sciences, University of South Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2025 \u2014 Healthcare Smart \u00d7 Medicine Deep"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI250959","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:36:23Z","timestamp":1754566583000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI250959"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,7]]},"ISBN":["9781643686080"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti250959","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,7]]}}}
