Models of Integrated Acute Care for Older Adult Inpatients That Incorporate Integrative Health: An Integrative Review

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.

Conduct an integrative review of studies on integrated acute-care models for older adult inpatients that incorporate integrative health services.

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.

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.

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.
