|Measure||Definition||Interview questions explored:|
|Acceptability||Cognitive and emotional responses to the project .||• General perceptions of the project and whether their expectations of the project had been met.|
Compatibility with the individual’s perceived role or their organisation’s culture resulting in an assessment of how relevant it is.|
Can reveal areas of “pushback” of an intervention that might otherwise not be apparent [51, 52].
• Views of the activities the participants were involved with.|
• Inclusion or exclusion of colleagues in the teams.
• Roles they were asked to play.
|Feasibility||Fit, practicality of the project.||
• Fitting implementation team activities into current workload.|
• How useful or practical they perceived the activities to be.
|Cost||Time burden and resource cost borne by participants. Cost usually refers to monetary cost or value for money but as HCP’s individual or group effort largely drove the interventions and they gave their time in kind, here we equated cost as value for contributed time .||• The amount of time and effort involved in the project.|
|Adoption||Extent to which participants changed their practice, or set an intention to do so, due to the project; here strongly associated with the primary outcome of referral rate.||
• How has the participant’s practice changed (personal behaviour)?|
