Intervention(s)
1) We have one information intervention (which will be the baseline control group), who will get an email message about suggested supply changes that will result in $X of savings.
2) We will have an altruism intervention, which gets information about supply swaps in addition to the following message: As a reminder, much of the cost incurred in the <procedure_name> procedure is charged to your patient. By agreeing to make the changes below, you would pass an estimated savings of $x on to your patients each year.
3) We will have a peer comparison intervention, which gets information about supply swaps in addition to the following message: We performed a cost analysis of all surgeons performing the <procedure_name> procedure, and found that your current DPC is more expensive than ___ (e.g, 9) out of ___ (e.g., 12) of your peers who do this procedure at UUHC. By agreeing to make the changes below, you would improve your cost ranking by X points (e.g., you would move to a rank of 3 out of 12 doctors performing this procedure).
4) We will have a financial incentives intervention, which gets information about supply swaps in addition to the following message: We recognize that your effort in cost reduction is beneficial to the hospital and would like to share that benefit with you. By agreeing to make the changes below, we will pay 30% of the first year’s savings that you generate into your division’s budget.
