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 friendcaregivers, 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 Twelve databases and gray literature sources will be searched for published and unpublished studies.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
