From: Factors influencing termination of resuscitation in children: a qualitative analysis
Domain 1: Research team and reflexivity
RTC and a Research Coordinator conducted the interviews.
RTC, TPC and ALN all are MDs. ARS has an MPH, and the Research Coordinator has a MS.
All members of the research team worked at Children’s Hospital Los Angeles.
Both interviewers are female.
5. Experience and training
Neither interviewers had prior experience in conducting interviews, but educated themselves extensively prior to conducting the interviews. TPC has had prior experience in conducting interviews and focus groups and was able to lend expertise and guide the interviewers.
6. Relationship established
RTC was a fellow physician/trainee, and had an established relationship with the participants. Participants were familiar with the Research Coordinator, but not all had worked directly with her.
7. Participant knowledge of the interviewer
The interviewers provided a brief overview of the study prior to beginning the interview.
8. Interviewer characteristics
RTC was a fellow and had not independently terminated a resuscitation. Thus, RTC did not have opinions as to which factors are most important when deciding when to terminate a resuscitation. The Research Coordinator was a non-clinician and did not have any opinions on the subject.
Domain 2: Study design
9. Methodological orientation and theory
Content analysis was the analytical approached used.
Purposeful sampling was used to generate an information-rich group with content expertise in the subject of interest.
11. Method of approach
Physicians were invited to participate via email.
12. Sample size
17 attending physicians at the study site participated.
No subjects approached refused to participate or dropped out.
14. Setting of data collection
Data was collected at the study site, in private offices.
15. Presence of non-participants
There were no other persons present during the interviews aside from the participant and interviewers.
16. Description of sample
Demographic data is provided in Table 1.
17. Interview guide
An interview guide was created drawing from concepts from the literature and by using a modified Delphi method.
18. Repeat interviews
Repeat interviews were not a part of the protocol of this study.
19. Audio/visual recording
Audio recordings were used to collect the data.
20. Field notes
Field notes were made during the interview.
The interviews lasted approximately 35 minutes on average.
22. Data saturation
Data saturation was achieved.
23. Transcripts returned
Transcripts were returned to participants for comment and/or correction.
Domain 3: Analysis and findings
24. Number of data coders
Two data coders (RTC and ARS) coded the data.
25. Description of the coding tree
A description of the coding tree is provided in the Methods and Results sections. The codebook can be found in the Appendix.
26. Derivation of themes
Themes were derived from the data.
Nvivo version 11 Pro was used to manage the data.
28. Participant checking
Participants were provided the opportunity to provide feedback on the findings.
29. Quotations presented
See Results section.
30. Data and findings consistent
There was consistency between the data presented and the findings.
31. Clarity of major themes
Major themes were clearly presented, as illustrated by the 5 broad categories of factors outlined in the Results section.
32. Clarity of minor themes
Extensive discussion of specific cases and minor themes took place in the Results section.
