Development and Application of the GheOPS-Tool Addendum on Potentially Inappropriate Prescribing (PIP) of Renally Excreted Active Drugs (READs) in Older Adults with Polypharmacy.

Background: Renal function progressively worsens with age. Potentially inappropriate prescribing (PIP) of renally excreted active drugs (READs) is common in older adults, leading to an increased rate of iatrogenic illness. The Ghent Older People's Prescription community Pharmacy Screening (GheOPS-) tool is an effective, explicit instrument that was developed for community pharmacists (CPs) to detect PIP.
