Index and subsequent 28\u2010day readmission were identified using ED data and hospital discharge records. ED diagnosis, Australian Refined Diagnosis\u2010Related Group (AR\u2010DRG) discharge codes, and ICD\u201010\u2010AM comorbidities were extracted. Multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations with 28\u2010day readmission. The study and findings have been reported against the STROBE\u2010RECORD guideline.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 28,730 initial patient visits, 7.9% re\u2010presented within 28\u2009days. The most common ED diagnoses at initial and readmission were chest pain (5.4% vs. 4.6%), falls (5.2% vs. 4.1%), dyspnoea (3.5% vs. 3.1%), abdominal pain (3.1% vs. 3.3%) and cerebrovascular accident (1.7% vs. 1.7%). The most frequent AR\u2010DRGs were respiratory infections\/inflammations, kidney and urinary signs\/symptoms, and other digestive system disorders. Key ICD\u201010\u2010AM codes associated with a higher likelihood of readmission within 28\u2009days were obstructive\/reflux uropathy (OR 2.66, 95% CI 1.78\u20133.96), urinary retention (OR 1.84, 95% CI 1.38\u20132.46), chronic ischaemic heart disease (OR 1.57, 95% CI 1.10\u20132.25), delirium (OR 1.35, 95% CI 1.07\u20131.71) and disorders of fluid, electrolyte, and acid\u2013base balance (OR 1.29, 95% CI 1.09\u20131.54).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Nearly 8% of older adults are readmitted within 28\u2009days.
