The risk factors for acute readmissions may differ from those affecting older adults in the community.

Of 2108 initial admissions, 328 (15.6%) resulted in an acute readmission, and 302 (14.3%) died within 30 days of follow-up. Notably, nearly half of the readmissions occurred within 1\u00a0week of discharge. Being a new care home resident (care home residency\u2009&lt;\u20093 months) was associated with acute readmission (HR 1.40), as was a medical history of cancer (HR 1.31), diabetes (HR 1.45), atrial fibrillation (HR 1.54), and COPD\/asthma (HR 1.36).
