Applying the consolidated framework for implementation research to evaluate the community rapid intervention service.

Background: Developed in 2019, the Community Rapid Intervention Service (CRIS) is a community intervention service aiming to prevent hospital admissions. CRIS provides a response within two hours to patients with sub-acute medical needs in their usual place of residence. This evaluation aimed to identify challenges and facilitators to implementation of the service, with a view to informing future service development, optimising patient care and disseminating learning to other areas looking to implement similar services.
