The outcome measure was readmission, defined as a CUD visit to health\u2010care at least 6\u2009months after initial CUD diagnosis. Hazard ratios (HR) were estimated using Cox survival analyses and flexible parametric survival analyses to assess risk of readmission and how the risk varied with age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>The vast majority of CUD visits took place in outpatient care (~80%). Approximately 23% of the included individuals were readmitted to care during follow\u2010up. The fully adjusted model showed an increased risk of readmission among those with schizophrenia and other psychotic disorders [HR\u2009=\u20091.54, 95% confidence interval (CI)\u2009=\u20091.29\u20131.84], low education (HR\u2009=\u20091.40, 95% CI\u2009=\u20091.24\u20131.57), personality disorders (HR\u2009=\u20091.27, 95% CI\u2009=\u20091.05\u20131.54) or mood disorders (HR\u2009=\u20091.27, 95% CI\u2009=\u20091.12\u20131.45).
