Initial Logic Model for the PET Intervention. The initial logic model focuses on the core levers of the intervention. An early finding of the evaluation was that the PET document was insignificant relative to the facilitation provided by the action researchers. Hence, facilitation skills are included as a key resource and the facilitation activities that supported PET’s delivery are listed in the activities section. The people involved in the study besides the action researchers, including HCPs, patients/PPI reps and PE/corporate teams, are also listed as an intervention resource as they were frequently identified as having contributed to outcomes. In addition, various mechanisms are included in the model that could be seen to be operating through the intervention, notably participation, reflection, feedback and action planning/QI cycles. The factors that moderated PET’s delivery, identified as either constraints on wards that struggled with implementation or enablers for achieving full implementation, are listed in the moderators section. Finally, while the ideal, distal outcome of a fully embedded patient experience system (with sustained improvements to patient experience occurring) was not achieved on any ward, the various proximal outcomes listed in the logic model could be identified across the participating wards
