Risk factors for inappropriate polypharmacy
Definition
use of multiple pharmacies and/or physicians

Patient determines Rx is not needed; Pt feels presence of some adverse effects; Pt belief that more (or different) medication is needed
Term
Factors that Impact Medication Adherence
Definition
1. Social/Economic factors (functional health literacy, income, med costs, insurance coverage); 2. Therapy related (complexity of med regimen, lack of immediate benefit, interference); 3. Patient-related (physical & psychological/behavioral); 4. Health System Related (quality of communication, lack of continuity of care, poor access, etc.)
Term
Inappropriate Prescribing
Definition
prescribing medications outside the bounds of accepted medical standards (risks outweighs potential benefits)
