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

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.

This study used the Consolidated Framework for Implementation Research (CFIR) as an evaluation framework. We conducted semi-structured interviews with local healthcare system leaders, clinicians that worked within the CRIS, and clinicians who interfaced with the CRIS. The CFIR was used to guide data collection and analysis. Two Community of Practice (CoP) meetings were held to gather stakeholders' perspectives of the evaluation.

Three key themes were identified from the analysis of 13 interviews: contextual factors influencing implementation, service identity and navigating complexity. Contextual factors such the influence of the Covid 19 pandemic upon health services and the expansion of the CRIS were discussed by participants. The adaptability of the service was deemed both a facilitator and challenge of implementation. Ways to build-on and improve the existing CRIS model were suggested.

This evaluation has shown that the CRIS may need to be redefined with clarity provided as to how the service interfaces with other urgent and planned care offered in acute, primary, community and social services. Structuring the evaluation around the CFIR was helpful in identifying facilitators and challenges that influenced the implementation of the CRIS.
