Detection of adverse drug events using an electronic trigger tool

American Journal of Health System Pharmacy (AJHP) September 1, 2016

Implementation and refinement of an integrated electronic "trigger tool" for detecting adverse drug events (ADEs) is described. A three-month prospective study was conducted at a large medical center to test and improve the positive predictive value (PPV) of an electronic health record-based tool for detecting ADEs associated with use of four "trigger drugs": the reversal agents flumazenil, naloxone, phytonadione, and protamine. On administration of a trigger drug to an adult patient, an electronic message was transmitted to two pharmacists, who reviewed cases in near real time (typically, on the same day) to detect actual or potential ADEs. In phase 1 of the study, any use of a trigger drug resulted in an alert message; in subsequent phases, the alerting criteria were narrowed on the basis of clinical criteria and laboratory data with the goal of refining the trigger tool's PPV.

Harmonization of technology across an integrated delivery network

American Journal of Health System Pharmacy (AJHP) July 15, 2018

A standardized blueprint for use when harmonizing or standardizing pharmacy automation and technology resources across individual institutions or an integrated delivery network (IDN) of institutions is described. Whether to strive for standardization (use of the same vendors and equipment) versus harmonization (use of various technologies to meet patient-specific needs and organizational stability requirements) and how to coordinate activities across IDNs consisting of 3-30 or more hospitals are common questions due to consolidations in the healthcare industry.
