Only 2 EPs mentioned a disadvantage (the wiki added stress). Among EPs, the most frequently reported advantage of using a wiki-based reminder was that it refreshes the memory (n = 14) among AHPs, it was that it provides rapid access to protocols (n = 16). We noted no other significant differences. Participating AHPs had more experience than eligible AHPs (mean 14 vs 11 years P =. Of 66 eligible EPs and 444 eligible AHPs, we invited 55 EPs and 39 AHPs to participate, and 25 EPs and 25 AHPs (15 nurses, 7 respiratory therapists, and 3 pharmacists) accepted. We retained some less frequently mentioned beliefs as well. We considered the 75% most frequently mentioned beliefs as salient. Two reviewers independently analyzed the content of the interview transcripts. Participants viewed a video showing a clinician using a wiki-based reminder, and we interviewed participants about their behavioral, control, and normative beliefs-that is, what they saw as advantages, disadvantages, barriers, and facilitators to their use of a reminder, and how they felt important referents would perceive their use of a reminder. Using univariate analyses, we assessed whether our participants’ gender, age, and level of experience were similar to those of all eligible individuals. We purposefully selected participants from three trauma centers in Quebec, Canada, to obtain a representative sample. Previous studies suggested a sample of 25 EPs and 25 AHPs. Drawing on the theory of planned behavior, we conducted semistructured interviews to elicit EPs’ and AHPs’ beliefs about using a wiki-based reminder.
