Abstract

Introduction: Adequate knowledge of biostatistics is essential for healthcare providers to stay up to date with medical advances and maintain an evidence-based practice. However, training in clinical research in Canadian residency programs varies considerably. Our study aimed to determine Canadian urology trainees’ knowledge of biostatistics and interpretation of the scientific literature.

Methods: We conducted a national survey of all Canadian urology residents and fellows, which assessed experiences with biostatistics, self-reported confidence with statistical questions, and knowledge of biostatistical concepts.

Results: Out of 201 urology trainees, 74 (36.8%) responded to the survey. The majority of respondents disagreed or strongly disagreed with the fact that they had sufficient training in biostatistics in medical school (67.6%) or that their current knowledge was sufficient for the rest of their career (66.1%). If given the chance, 82.3% of respondents would like to learn more about biostatistics. About half of respondents were able to correctly identify ordinal variables (51.5%), discrete variables (52.9%), or interpret adjusted odds ratios (50.0%). Despite senior residents reporting more confidence on biostatistical questions, our results did not demonstrate significant differences in overall knowledge according to level of training or experience with biostatistics.

Conclusions: Our results identified important knowledge gaps among current Canadian urology trainees. Most trainees do not believe they have sufficient training in biostatistics. Knowledge of basic statistical concepts was lower than expected and did not significantly differ according to level of training. Our results highlight the need for structured, dedicated training in biostatistics for urology trainees within the new Competence by Design teaching framework.
