From Nursing Homes to Geriatric Psychiatry: Contextual Factors Associated With the Admission of People With Dementia and Behaviour That Challenges—An Integrative Review

ABSTRACT Aim To systematically identify the contextual factors leading to (re) admission to psychiatry of people with dementia and behaviour that challenges living in nursing homes. Behaviour that challenges is understood as a social construct that reflects individual and environmental factors and their interaction. Design The 5‐step Whittemore structural and systemic barriers and lack of effective interprofessional and patient‐centred collaboration. Conclusion Dementia crises often lead to hospitalisation. A key crisis‐determining factor is interprofessional collaboration. High‐quality studies on this topic are lacking. The existing results originate mainly from Europe and should be interpreted with caution in view of contextual and methodological limitations. Policymakers should promote cross‐sector care models, the deployment of psychiatric crisis teams, Advance Care Planning and digital communication tools. Reporting Method We based our reporting on the PRISMA 2020 statement. Patient or Public Contribution No patient or public contribution.
