Analysis
Thematic analysis of the transcribed interviews was performed through an iterative process of inductive and deductive coding.23Inductive codes were identified through topics emerging from transcripts, while deductive codes were identified a priori from prior research and the interview guide.8 Each transcript was independently coded by two researchers (AW/MS) and memos were made to identify emerging themes and data interpretation.(Appendix 2) All coding discrepancies were resolved via consensus discussions between the coders and final coding assignments were made using NVivo 12.19 Although thematic saturation was achieved at 12 interviews, we continued conducting interviews because we had a finite number of participants, all of whom had unique clinical experiences with UTx and whose insights, we believed, were additive to the study results.
Quantitative data analysis entailed descriptive statistics (e.g., frequencies, medians, interquartile ranges, and means) for patient demographic and outcomes data. In addition, qualitative codes were transformed into categorical variables (e.g., perceived high or low risk of UTx, information needs, and expectations of UTx). Bivariate analysis, performed using R , tested associations between transformed qualitative data and quantitative demographic and outcomes data.24 Statistical significance was defined as p<0.05.
