Graphical timeline software for inpatient medication review

MedHistory is a web-based software module that graphically displays medication usage (y-axis) against time (x-axis). We set out to examine whether MedHistory would improve clinician's interactions with the medical record system. The authors invited house-officers at our institution to complete a survey about inpatient medication administration before and after using MedHistory. Detailed logs were also kept for 1 year after the study period. Compared to the pre-intervention survey, the post-intervention survey found that reviewing medication history was easier (pre: 13.2% vs post: 32.4%, p = .008), that medication review now fit within resident workflow (38.9% vs 75.7%, p < .001), and that there was increased satisfaction with the electronic health records software (2.6% vs 29.7%, p = .002). Additionally, determining the timing (29% vs 50.1%, p = .045) and dosing history (21.1% vs. 43.2%, p = .036) of inpatient medication administration was easier with MedHistory. Anti-infective agents and drugs requiring frequent adjustments were the most commonly reviewed. A graphical timeline of inpatient medications (MedHistory) was met with favorable response across multiple areas, including efficiency, speed, safety, and workflow.
