An area under the receiver operating characteristic curve (AUC) of 71.9% (95% CI=69.4% to 74.4%) was found. For this model, liver disease showed to be the strongest predictor with an OR of 10.7 (95% CI=2.4 to 46.6). The models for POB and NER showed AUCs of 73.0% (95% CI=70.7% to 75.4%) and 76.6% (95% CI=73.2% to 80.0%), respectively. For delirium an AUC of 85.9% (95% CI=83.8% to 87.9%) was found, and for the predictive algorithms for luxation and VTE we found least favourable results (AUC=58.4% (95% CI=55.0% to 61.8%) and AUC=66.3% (95% CI=62.7% to 69.9%)).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Discriminative ability was reasonable for SSI and predicted probabilities ranged from 0.01% to 51.0%. We expect this to enhance shared decision-making in considering THA or TKA since current counselling is predicated on population-based probability of risk, rather than using personalised prediction. We consider our models for SSI, delirium and NER appropriate for clinical use when taking underestimation and overestimation of predicted risk into account. For VTE and POB, caution concerning overestimation exceeding a predicted probability of 0.08 for VTE and 0.05 for POB should be taken into account. Furthermore, future studies should evaluate clinical impact and whether the models are feasible in an external population.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bmjopen-2022-062065","type":"journal-article","created":{"date-parts":[[2022,8,24]],"date-time":"2022-08-24T11:21:31Z","timestamp":1661340091000},"page":"e062065","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":16,"title":["Development of prediction models for complications after primary total hip and knee arthroplasty: a single-centre retrospective cohort study in the Netherlands"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6940-3367","authenticated-orcid":false,"given":"Lieke","family":"Sweerts","sequence":"first","affiliation":[{"name":"Radboud Institute of Health Sciences, Department of Orthopaedics, Radboud university medical center, Nijmegen, The Netherlands"},{"name":"Radboud Institute of Health Sciences, IQ healthcare, Radboud university medical center, Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas J","family":"Hoogeboom","sequence":"additional","affiliation":[{"name":"Radboud Institute of Health Sciences, IQ healthcare, Radboud university medical center, Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thierry","family":"van Wessel","sequence":"additional","affiliation":[{"name":"Radboud Institute of Health Sciences, Department of Orthopaedics, Radboud university medical center, Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip J","family":"van der Wees","sequence":"additional","affiliation":[{"name":"Radboud Institute of Health Sciences, IQ healthcare, Radboud university medical center, Nijmegen, The Netherlands"},{"name":"Radboud Institute for Health Sciences, Department of Rehabilitation, Radboud university medical center, Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastiaan A W","family":"van de Groes","sequence":"additional","affiliation":[{"name":"Radboud Institute of Health Sciences, Department of Orthopaedics, Radboud university medical center, Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,8,24]]},"reference":[{"key":"2025101814451197000_12.8.e062065.1","doi-asserted-by":"publisher","DOI":"10.1007\/s10067-011-1835-x"},{"key":"2025101814451197000_12.8.e062065.2","doi-asserted-by":"publisher","DOI":"10.1186\/1472-6963-12-225"},{"key":"2025101814451197000_12.8.e062065.3","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2018-021784"},{"key":"2025101814451197000_12.8.e062065.4","doi-asserted-by":"publisher","DOI":"10.1002\/art.37901"},{"key":"2025101814451197000_12.8.e062065.5","doi-asserted-by":"crossref","first-page":"864","DOI":"10.5312\/wjo.v6.i11.864","article-title":"Role of decision AIDS in orthopaedic surgery","volume":"6","author":"Ten Have","year":"2015","journal-title":"World J Orthop"},{"key":"2025101814451197000_12.8.e062065.6","doi-asserted-by":"crossref","first-page":"660","DOI":"10.1007\/s11606-013-2455-8","article-title":"Bringing big data to personalized healthcare: a patient-centered framework","volume":"28 Suppl 3","author":"Chawla","year":"2013","journal-title":"J Gen Intern Med"},{"key":"2025101814451197000_12.8.e062065.7","first-page":"403","article-title":"Idealistic, impractical, impossible?
