Hypothesis
Can a computerized decision aid improve the medical knowledge of patients with early stage papillary thyroid cancer considering radioactive iodine remnant ablation?
Conclusion
The study found that a patient-directed computerized decision aid significantly improved medical knowledge in patients with early stage papillary thyroid cancer.
Supporting Evidence
- The decision aid improved medical knowledge scores from 8.04 to 9.42 out of 10.
- Participants found the decision aid easy to navigate and use.
- Most participants were comfortable with computers and had a higher education level.
Takeaway
This study created a helpful online tool to teach patients about their thyroid cancer treatment options, and it worked well to improve their understanding.
Methodology
Participants completed a medical knowledge questionnaire before and after using the decision aid, and usability was assessed using an adapted System Usability Scale.
Potential Biases
Participants were predominantly well-educated and comfortable with technology, which may not represent the broader patient population.
Limitations
The study's findings may not be generalizable due to the high comfort level with computers among participants and the fact that many had already made their treatment decision before using the decision aid.
Participant Demographics
82% female, most had a college education or higher, and were comfortable using computers.
