Recently I read an interesting article in the American Journal of Health-System Pharmacy. The question of what defines a pharmacy informaticist was raised. Iâ€™ve mused over that question many times myself. Because there is no standardized definition for a pharmacy informaticist, it is extremely difficult to define their role. A look at the many different job descriptions for IT pharmacists posted on the American Society of Health-System Pharmacists (ASHP) website is testimony to that.
