Summary

The subjects in this study are physicians working in the Wishard Emergency Department. The purpose of this study is to measure the extent to which information technology (i.e.-computers) improves emergency department care. The objective of our study is to evaluate the use of informatics in the emergency department and specifically to determine if computer reminder systems: 1) reduce the number of unsafe medications prescribed to older adults, 2) assist in more safely dosing of medications to adults of all ages, and 3) increase influenza immunization of eligible older patients in the emergency department. Interventions: The interventions in this study are computer reminders. When releasing patients from the emergency department, physicians currently write all release orders, including prescriptions, on a computer order entry system that is linked to the Regenstrief Medical Record System. The computerized order entry system will be programmed so that physicians randomized (randomly placed) into the intervention group, the group that will receive the intervention, they will receive one of three types of reminders: 1. The medication prescribed is generally considered unsafe for use in older patients. The reminder will then list appropriate alternatives for this medication. 2. The dose of the prescribed medication is excessive and should be adjusted for the patient's creatinine clearance (or kidney function). 3. This patient may be eligible for influenza vaccination. The physician will then choose to order or disregard the recommendation. The computer system will automatically record what the physician selected to do. The general outcome of interest is the extent to which the electronic reminders successfully improved physician practice in the emergency department setting. This outcome will be compared to physicians who were randomized to the group that did not receive the reminders (the control group).
