Routine health insurance claims (HIC) data are a valuable resource, comprising standardized longitudinal patient information. However, to fully leverage ML in HIC, challenges such as large data volumes, variability, data gaps, sparsity, and high dimensionality must be addressed. To overcome these barriers, our publicly funded KI-THRUST project accessed a large-scale dataset of 2 million anonymized routine insurance records from four German providers. Subsequently, a thorough performance evaluation of various linear and nonlinear ML models (logistic regression, AdaBoost, Random Forest, Neural Network) for their potential to predict clinical outcomes such as mortality and unplanned readmissions was conducted, and the results were interpreted using explainable AI methods (Integrated Gradients, Shapley values, LIME). In particular, we investigated the predictive value of feature sets comprising base demographics (M1) and ICD-10 codes for previous conditions and procedures (M2, M3). While AdaBoost achieved the best overall performance, the less complex logistic regression performed comparably. The additional diagnostic and procedural information in M2 led to a significant performance gain, whereas additional time-related information did not. Overall, our results show the potential of large-scale HIC data when combined with ML methods and XAI. Ultimately, paving the way for future applications like discharge management systems and other healthcare areas.<\/jats:p>","DOI":"10.3233\/shti260183","type":"book-chapter","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T21:57:35Z","timestamp":1779400655000},"source":"Crossref","is-referenced-by-count":0,"title":["Evaluating the Potential of Machine Learning for Discharge Management on Routine Health Insurance Data"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1330-6178","authenticated-orcid":false,"given":"Zully","family":"Ritter","sequence":"first","affiliation":[{"name":"Department of Medical Informatics, University Medical Center G\u00f6ttingen, Germany"},{"name":"Emergency Department, University Medical Center G\u00f6ttingen, Germany"},{"name":"University of G\u00f6ttingen, Campus Institute Data Science, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7696-3931","authenticated-orcid":false,"given":"Miriam Cindy","family":"Maurer","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics, University Medical Center G\u00f6ttingen, Germany"},{"name":"University of G\u00f6ttingen, Campus Institute Data Science, G\u00f6ttingen, Germany"},{"name":"Dpt of Predictive Deep Learning in Medicine and Healthcare, Justus-Liebig University Gie\u00dfen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7517-7041","authenticated-orcid":false,"given":"Jacqueline Michelle","family":"Metsch","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics, University Medical Center G\u00f6ttingen, Germany"},{"name":"University of G\u00f6ttingen, Campus Institute Data Science, G\u00f6ttingen, Germany"},{"name":"Dpt of Predictive Deep Learning in Medicine and Healthcare, Justus-Liebig University Gie\u00dfen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0560-7680","authenticated-orcid":false,"given":"Lisa","family":"Weller","sequence":"additional","affiliation":[{"name":"aQua Institute for Applied Quality Improvement and Research in Health Care, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thorsten","family":"Pollmann","sequence":"additional","affiliation":[{"name":"aQua Institute for Applied Quality Improvement and Research in Health Care, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathias","family":"Kretzler","sequence":"additional","affiliation":[{"name":"BKK Dachverband, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Grobe","sequence":"additional","affiliation":[{"name":"aQua Institute for Applied Quality Improvement and Research in Health Care, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7499-4373","authenticated-orcid":false,"given":"Anne-Christin","family":"Hauschild","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics, University Medical Center G\u00f6ttingen, Germany"},{"name":"University of G\u00f6ttingen, Campus Institute Data Science, G\u00f6ttingen, Germany"},{"name":"Dpt of Predictive Deep Learning in Medicine and Healthcare, Justus-Liebig University Gie\u00dfen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Opening the Personal Gate between Technology and Health Care"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI260183","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T21:57:35Z","timestamp":1779400655000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI260183"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,21]]},"ISBN":["9781643686615"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti260183","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,5,21]]}}}
