Costs saved and avoided from pharmacist interventions to address drug-related problems identified from outpatient clinics in Jordan.

The study revealed that pharmacists have provided cognitive input to rationalize and optimize the medication use and prevent errors, that led to the reported projected avoided and saved expenditures via various interventions to address drug-related problems. This highlights the added economic impact to the clinical impact of drug-related problems on patients and the healthcare system. The high prevalence and cost of drug-related problems offer strong rationale for pharmacists to provide more vigilant intervention to improve patient outcomes while maintaining cost effectiveness.
