Impact of Discharge Medication Reconciliation Across a Five-Hospital Health System.

PURPOSE

Hospital readmission of a primary diagnosis can have a substantial financial impact via reductions in reimbursement rates up to 3%, and have a negative impact on the lives of patients. Discharge medication reconciliation (DMR) can reduce medication errors that play a role in readmission. The objective of this study is to evaluate the impact of expanding pharmacist-led DMR across a four hospital health system on 30-day readmission rate for high risk of readmission disease groups.

METHODS

During the 3-month period, DMR was performed for patients with at least one of the disease states associated with a high risk for 30-day readmission, including chronic obstructive pulmonary disease, pneumonia, congestive heart failure, or acute myocardial infarction.

RESULTS

The 30-day readmission rate for patients with a high risk for readmission disease state significantly decreased from 17.5% to 15.5% in the pre-expansion to postexpansion phase, respectively ( p = .003). Discharge medication reconciliation capture rate increased from 28% pre-expansion to 35% postexpansion. After expansion, the number of DMR interventions reported by pharmacists increased 2.93 times.

CONCLUSION

Expansion of pharmacist-led DMR as a form of transitions of care significantly decreased 30-day readmission rate for high risk of readmission disease groups.
