Nursing interventions to improve care of people living with dementia in hospital: A mixed methods systematic review.

BACKGROUND: There are growing numbers of people living with dementia being admitted to acute care hospitals. Hospitalization for people living with dementia can be difficult and is often associated with negative outcomes. Nurses play a significant role in shaping the hospital experience of people living with dementia, and there have been efforts to design, implement and evaluate interventions to improve nursing care of people living with dementia. OBJECTIVE: To synthesize evidence on the effectiveness of, and experiences with, nursing interventions to improve care of hospitalized people living with dementia. DESIGN: Mixed methods systematic review following the JBI convergent segregated approach to synthesis and integration of findings. METHODS: The quantitative component considered studies that evaluated nursing interventions to improve the care of people living with dementia in hospital, comparing the intervention to usual care, other therapeutic modalities, or no comparator. The qualitative component considered studies that explored the experiences of nursing interventions from the perspectives of people living with dementia, caregivers, and nurses. A total of 8 databases were used to search for published and unpublished studies. Titles, abstracts, and full text selections were screened by two or more independent reviewers and assessed for methodological quality. RESULTS: A total of 38 studies were included in the review, 24 quantitative, 9 qualitative and 5 mixed method designs. Critical appraisal scores were moderate. All studies regardless of methodological quality were included in the review. Interventions were grouped as principally related to (1) dementia education for nurses, (2) technology, (3) nursing skills, and (4) physical environment. Outcomes are presented related to health outcomes of people living with dementia; nurses' knowledge, confidence, and self-efficacy; and health system outcomes. As the interventions were heterogeneous, a meta-analysis of quantitative findings was not possible. The qualitative analysis incorporated 60 findings from 12 studies and led to nine categories and two synthesized findings recognizing external influences on nurses' practice with people living with dementia and the importance of interventions to humanize nurses' work with people living with dementia. Integration of the quantitative and qualitative results demonstrates the need to recognize the role of organization- and unit-level factors in the design and implementation of effective interventions. CONCLUSIONS: There is limited high-quality evidence to demonstrate the effectiveness of interventions to improve nursing care of people living with dementia in hospital. Using approaches to intervention design and implementation that draw on models of behavior change and learning health systems may support effective change.

Interventions to Improve the Nursing Care of People with Dementia in Canadian Hospitals: An Environmental Scan.

As the number of people with dementia admitted to hospitals is expected to grow, now is the time to identify methods to improve nursing care of this population. We conducted an environmental scan to identify and describe interventions in Canadian hospitals to improve the nursing care of people with dementia, how they are being evaluated and what issues influence the success of interventions. Methods included a search of published and unpublished literature and key stakeholder interviews. Interventions are described under three categories: (1) interventions to improve nurses' knowledge, attitudes and skills; (2) interventions to address responsive behaviours; and (3) interventions to help nurses individualize care. The evaluation of interventions rarely included an evaluation of effectiveness and more often included a qualitative evaluation of nurses' experiences with interventions. We summarize the factors affecting the implementation of interventions following the Consolidated Framework for Implementation Research (Damschroder et al. 2009) and suggest strategies for supporting the success of interventions to improve patient care and the experiences of nurses working with people with dementia.

Nursing interventions to improve care of people with dementia in hospital: a mixed methods systematic review protocol.

OBJECTIVE: This review will focus on the effectiveness of, and experience with, nursing interventions to improve the care of people with dementia in hospital. INTRODUCTION: Acute care for people with dementia has been identified as an area for improvement. Admission to hospital can be upsetting and difficult for people with dementia and can be associated with negative outcomes. Nurses play a significant role in shaping the experience of hospitalization and are the focus of many related interventions. INCLUSION CRITERIA: This mixed methods review will examine literature on improving acute care for people with dementia. The quantitative component will consider studies that evaluate nursing interventions to improve care of people with dementia, comparing the intervention with usual care, other therapies, or no comparator. Outcomes will include behavioral, health, and health system indicators. The qualitative component will consider studies that explore the experience of nursing interventions from the perspective of people with dementia, their family- or friend-caregivers, and nurses. METHODS: This review will be conducted in accordance with JBI methodology for mixed methods systematic reviews. Twelve databases and gray literature sources will be searched for published and unpublished studies. Titles, abstracts, and full-text selections will be screened by two or more independent reviewers and assessed for methodological validity using the standard JBI critical assessment tools. This review will follow a convergent segregated approach to data synthesis and integration. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42021230951.
