Teaching physicians the GPGP method promotes deprescribing in both inpatient and outpatient settings.

Background: In complex older patients, inappropriate medication use and polypharmacy (IMUP) are commonplace and increasing exponentially. Reducing IMUP is a challenge in multiple clinical contexts, including acute admission and family practice, due to several key barriers. In the global effort against this epidemic, educational programs geared toward changing physicians' prescribing patterns represent an important means of promoting deprescribing.
