Clinical Decision Support and Appropriateness of Antimicrobial Prescribing: A Randomized Trial

Interview with Matthew H. Samore, MD, author of Clinical Decision Support and Appropriateness of Antimicrobial Prescribing: A Randomized Trial, published in the November 9 issue of JAMA, the Journal of the American Medical Association. Summary points: 1. Repetitive use of a diagnostic and treatment algorithm to ingrain new prescribing habits was a valuable part of this practice change intervention. 2. Clinical decision support systems (CDSS) are feasibly implemented in practice settings that lack electronic medical records, including rural communities. 3. CDSS needs to be integrated with tools that save clinicians' time to be sustainable.
