Dear Anil,
Welcome to the Board.
In response to your original query, the Decision Support feature is a little confusing at first. To see how it works, check out the Help section. Search in AC Help under "Use The Health Maintenance (Decision Support) Module."
In my use of DS I find it a helpful reminder especially for somewhat obscure recommendations like checking for AAA which is only for men who have every smoked between 65-75. Before using AC I never remembered to do this. With AC I'm doing much better.
The other nice thing is the ability to enter customized recommendations for DS within the Administration section. I have added several things not in the standard USPSTF advice.
Once you get used to using DS it's very quick to go through. You can also delegate some or all of the task to a medical assistant.
With best wishes,
John
