Process evaluation measures for the RaDIANT Community intervention
| Dimension | Process Evaluation Questions | Measurement |
|---|---|---|
| Fidelity | To what extent was the intervention delivered as planned? | Facility-level participation (Y/N) in each required and optional intervention component and in all required and optional intervention activitiesa Composite fidelity index of the number of intervention components completed (0–14) |
| Sustainability | To what extent are intervention activities perceived as helpful? To what extent are dialysis facilities willing to continue intervention activities indefinitely? How can the intervention be improved for dissemination? |
Staff-perceived helpfulness of intervention activities (Likert scale) Willingness to continue intervention activities (yes/no) based on perceived helpfulness Open-ended questions regarding suggestions for improving select intervention activities |
| Reach | To what extent did its intended audience receive the intervention? | Proportion of patients receiving each patient-level intervention component and the full multicomponent interventionb |
| Context | What barriers may prevent patients at intervention facilities from beginning or completing the transplant evaluation process? What non-intervention educational materials or resources were provided to patients at intervention facilities? |
Itemized checklist at end of questionnaire Facility-level distribution (Y/N) of non-RaDIANT educational resources to dialysis patients |
| Linking process data to intervention outcomes | To what extent does facility level referral for kidney transplantation vary by implementation fidelity among intervention facilities pre- and post-intervention? | Association between fidelity index (0–14) and mean difference in proportion of patients referred for kidney transplantation in the 2014 intervention year |
a Intervention facilities were required to complete 9 mandatory intervention activities, as well as 2 “optional” intervention activities
b Receipt of an intervention component is defined as receiving care at a facility that adopted the intervention component
