Online Field Test of an Appendicitis Decision Support Tool

January 20, 2022 updated by: David Flum, University of Washington
After the recent publication of the CODA Trial comparing antibiotics and surgery for acute appendicitis, the investigators developed a comprehensive decision support tool. This tool will help patients understand the risks and benefits of each treatment and make a treatment decision. This study is an online randomized field test comparing the decision support tool to a control infographic and assessing it's affect on decisional outcomes, such as decisional conflict.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Decisional Conflict Pre vs. Post Intervention
Time Frame: At time of enrollment
Assessed using the validated decisional conflict scale comparing only participants in the intervention arm before and after viewing the decision support tool.
At time of enrollment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Decisional Conflict Between Arms
Time Frame: At time of enrollment
Total score on the validated decisional conflict scale after viewing the intervention support tool or the control infographic. Scale ranges from 0-100 with higher scores being worse.
At time of enrollment
Acceptability
Time Frame: At time of enrollment
Between arm comparison of the acceptability of the information presented to the participants rated on a 4 point acceptability scale with higher scores representing higher acceptability.
At time of enrollment
Trust and Accuracy of Information
Time Frame: At time of enrollment
