Description
Summary:Background The Acute Care for Elders (ACE) unit model of care aims to reduce common complications of hospitalization in older adults through early involvement of allied health providers, changes to the care environment, elder‐friendly care protocols, and proactive discharge planning. Our hospital established a dedicated 28‐bed medical ACE unit. Because of capacity limitations, the number of eligible older medical patients often exceeds the available number of beds. Thus, some ACE unit‐eligible patients are instead admitted to other medical or surgical units for their medical care. These “bed‐spaced” ACE patients receive care by the same general internists and ACE order set that ACE unit patients are cared under. We sought to compare the health outcomes of ACE‐designated patients admitted to the ACE unit versus bed‐spaced peers cared for using a protocolized ACE order set. Methods 3046 ACE‐designated patient admissions were analyzed (1499 ACE unit and 1547 bed‐spaced). The primary outcomes examined were discharge disposition and in‐hospital mortality. Univariate and multivariate comparisons were performed. Propensity matching was used to adjust for case mix in a post‐hoc analysis. Results The mean age of participants was 83.5 years for ACE unit patients and 82.6 for bedspaced patients. In adjusted models, ACE unit patients were more likely to be discharged home (OR 1.28 [1.08–1.50], p = 0.003). In an unadjusted analysis, patients admitted to ACE unit were less likely to die in hospital, but this finding did not persist after adjustment for case mix. Conclusion Care of older adults delivered on a dedicated ACE unit increases the likelihood of discharge to home when compared to care delivered with an ACE order set alone for general internal medicine patients.
