From expected to actual barriers and facilitators when implementing a new screening tool: A qualitative study applying the Theoretical Domains Framework

Abstract
Aim and objectives
To identify determinants for using a new screening tool to identify older patients eligible for targeted nurse-led intervention, as perceived by healthcare professionals implementing the tool, and to examine how these perceptions changed over time.

Design
A cross-sectoral longitudinal qualitative study based on semi-structured interviews with healthcare professionals in a Danish hospital and two collaborating municipalities.

Methods
In three focus groups, seven single interviews and a workshop, we examined the healthcare professionals' perceptions of and attitudes towards the new screening tool before, during and after the implementation. The Theoretical Domains Framework was used to identify the healthcare professionals' perception of barriers and facilitators, followed by content analysis. The results were further discussed using the COM-B system as an analytic framework. This qualitative study is reported according to the Consolidated Criteria for Reporting Qualitative Studies (COREQ) checklist.
