Adoption (patient & provider acceptability)
Acceptability of the intervention was assessed from participants in the intervention arms (PPKAY, PPKAY with standard and personalized boosters) with 15 questions in a post-treatment survey and interview. We asked 5 questions about satisfaction with various domains as well as perceived usefulness, each with structured response options. We also asked 4 open-ended questions on the overall structure and content of the intervention.During post-trial debriefing, we conducted a focus group discussion with our research nurses and research team. During this discussion, after informed consent, nurses were asked about the complexity of the intervention, eagerness to administer PPKAY, and workload. The focus group sessions were audio recorded and transcribed. We used inductive coding to understand the nurses’ perceptions about the overall trial protocol, patient and nurse acceptability of the intervention, trial process feasibility and fidelity, and perceived impact of the intervention.
