Abstract
BACKGROUND: The use of integrated acute care for older adult inpatients is a growing field, especially the use of integrative health-care practices for managing complex, chronic, age-related health conditions. Scientific evidence suggests that these practices should be incorporated into older adult inpatients' daily care. AIM: Conduct an integrative review of studies on integrated acute-care models for older adult inpatients that incorporate integrative health services. METHODS: We searched Medline Ovid ALL, Embase.com, CINAHL, APA PsycINFO Ovid, Web of Science Core Collection, ProQuest Dissertations & Theses A&I, Cochrane Library, and CAMBase bibliographic databases for studies, published between 1990 and 2023, on integrated acute-care models for older adult inpatients that incorporated integrative health services. The search associated the domains of acute care, geriatrics, internal medicine, rehabilitation, hospitalization, geriatric psychiatry, integrated/integrative care, care models, practices and coordination, interprofessionalism and multidisciplinarity, collaborative practices, and complementary therapies. The review was completed in June 2024. RESULTS: We retained 32 studies conducted in North America, Europe, Australia, and Asia, including 46,899 older adult inpatients, 39 physicians, 148 nurses, 695 allied health-care professionals, and 358 informal caregivers. Three integrated acute care models were identified: the Acute Care for Elders model, the Integrated General Hospital model, and the Transitional Care model. Three integrated acute psychogeriatric-care models were identified: the Admiral Nursing model, the Lewy body dementia Admiral nursing service model, and the Care for Acute Mentally Infirm Elders model. A single, hybrid, Integrated, People-Centred Health Services model for acute and community health care was identified. We found the Scaling Integrated Care in Context model for measuring integrated care development within health-care systems. CONCLUSION: Few studies have investigated integrated acute-care models incorporating integrative health services for older adult inpatients. Existing acute-care models including integrative medicine should be explored further, and new, more inclusive models should be developed.
