A multivariate logistic regression model was used to identify potential predictors of OHCA. Considering the effect of COVID-19, data-sets from 2019 and 2020 were used as external validation. The model\u2019s performance was evaluated using receiver operating characteristic (ROC) curves and confusion matrix metrics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0007125025104273_as4\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Out of 104 022 geriatric patients with depression, 2479 (2.4%) experienced OHCA. Significant predictors of OHCA included age, male gender, previous utilisation of medical resources, renal failure with haemodialysis, existing comorbidities, medication changes and recent psychotherapy. The ROC values for the predictive models ranged from 0.707 to 0.771 in the 2019 and 2020 external validations for 7-, 30- and 90-day OHCA. For 2019, the 7-day model demonstrated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of 0.600, 0.718, 2.130, 0.560 and 3.840, respectively. For 2020, these metrics for the 7-day model were 0.775, 0.655, 2.250, 0.340 and 6.550, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0007125025104273_as5\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study developed and validated a predictive model for OHCA in older patients with depression.
