Study design and methods
Design
- Physicians were invited to participate in an online educational study.
- The intervention group was offered web-based training before completing the knowledge survey.
- The control group completed the survey before receiving the training.
Analysis
- Chi-square tests were used for categorical outcomes.
- t-tests were used for continuous outcomes.
- Logistic regression estimated adjusted odds ratios and 95% confidence intervals.
- Analyses were conducted using SAS 9.3.
Limitations reported by the authors
- No baseline knowledge survey was administered, limiting assessment of change from baseline.
- The sample was small, with low participation relative to the number invited.
- Selection bias is possible because participants may have had greater interest in genetics.
- Compliance with viewing the video was not monitored.
What the findings do and do not establish
The results support an association between the educational intervention and higher correct-response rates on several knowledge questions. They do not establish long-term retention, changes in clinical practice, or improved patient outcomes.
