Data analysis
Interviews were digitally recorded and professionally transcribed verbatim. All transcripts were reviewed for accuracy and identifying information was removed prior to analyses. Each interview was double coded for emergent themes by two independent researchers using NVivo 12 (QSR International). Coding was merged and reviewed by a third researcher; discrepancies in coding were discussed until consensus was reached. Responses were compared within and across participants to determine emergent themes. Participant demographics were summarized using means and standard deviations for continuous variables and proportions for categorical variables.
