Q

Should you report small effect sizes to patients when giving them a response to a DI question?

A

Yes, even small effect sizes are necessary information to give to a patient. If there was a surgery with a 97% rate but a 3% rate of major complications, depending on the patient they may make a different decision based on these results

Q

Why is it important to document any DI request, no matter the severity?
