The Number Needed to Remind: a Measure for Assessing CDS Effectiveness.

Background: Clinical decision support (CDS) is associated with improvement in quality and efficiency in healthcare delivery. The appropriate way to evaluate its effectiveness remains uncertain.

Methods: We analyzed data from our electronic health record (EHR) measuring the display frequency of eight reminders for Coronary Artery disease and Type 2 Diabetes and their associated performance according to a predefined methodology.

A qualitative study of the activities performed by people involved in clinical decision support: recommended practices for success.

Objective: To describe the activities performed by people involved in clinical decision support (CDS) at leading sites.

Materials And Methods: We conducted ethnographic observations at seven diverse sites with a history of excellence in CDS using the Rapid Assessment Process and analyzed the data using a series of card sorts, informed by Linstone's Multiple Perspectives Model.

Results: We identified 18 activities and grouped them into four areas.
