Inappropriate medication prescribing to older patients increases the risk of adverse drug events. This retrospective study assessed the sustainability of orally communicated medication recommendations based on the STOPP (Screening Tool of Older Persons potentially inappropriate Prescriptions) and START (Screening Tool to Alert Doctors to Right Treatment) criteria as compared to written medication review over time. The prevalence of potentially inappropriate prescriptions remained lower in the group receiving the orally communicated recommendations at 24-month follow-up. The authors conclude that direct communication about medications between pharmacists and prescribing providers may be more effective than written medication review.
