  • *Percentages for specific PIM classes represent the % of that class among all PIM prescriptions.

  • †P value represents general time series model assuming a Poisson distribution.

  • EQUIPPED, Enhancing quality of prescribing practices for older adults discharged from the Emergency Department; PIMs, potentially inappropriate medications.
