Background:
Patients hospitalized with Parkinson's disease (PD) require timely delivery of carbidopa-levodopa (C/L) medication. Ill-timed administration of C/L doses is associated with greater morbidity and longer lengths of stay.
Objective:
To understand the barriers to timely C/L administration, and implement strategies to improve the administration of the drug to hospitalized PD patients.
Methods:
Several key strategies were employed in 2015 to improve the timely delivery of C/L doses: 1. three kinds of nursing alert in the electronic medical record (EMR); 2. staff in-service education; 3. stocking immediate-release C/L into automated medication dispensing machines on key hospital units; 4. reports to nurse unit managers on timeliness of C/L administration; and 5. reconciliation of inpatient and outpatient levodopa orders by the hospital pharmacist upon admission. The primary outcome was the percent of C/L doses administered within 60, 30, and 15 minutes of scheduled time.
Results:
Our urban hospital, affiliated with a Parkinson's Foundation Center of Excellence, had 5,939 C/L administrations in 2018. There was sustained improvement in timely delivery of doses, from 89.3% in 2012 to 96.5% in 2018 (within 60 minutes of the scheduled time), 65.5% to 86.4% (30 minutes), and 42.3% to 71.1% (15 minutes) (all p < 0.001).
Conclusions:
With multifaceted but relatively simple measures, we were able to "change the culture" so that hospitalized patients with Parkinson's disease receive levodopa on time.
