Background: For Parkinson's disease (PD) patients, adherence to a regular PD medication schedule is important in achieving optimal symptom control. There are few published studies quantifying PD medication administrations in hospitalized PD patients. Methods: Hospitalization records for 100 veterans with idiopathic PD and admitted to our center were reviewed to determine the on time rate and contraindicated medication doses. A barcode based computerized medication administration system within the electronic medical record provided information of the exact time the medication was given to a patient. Results: Eighty-nine idiopathic PD patients met study inclusion criteria. Among them, 87 were on levodopa monotherapy or in combination with other PD medications. Two patients were on dopamine agonists only. A total of 3873 doses of PD medications were prescribed during hospitalization. Among 675 incorrect medication administrations, 322 doses were omitted, 300 doses late by ≥30 min, and 53 doses given early by ≥30 min. Contraindicated medications were prescribed for 19 patients. The correct administration percentage was lower during the first 2 days post-admission compared to subsequent days (mean 74.6% vs. 82.8%) and higher for patients who had neurological consultations (mean 85.5% vs. 76.5%). Correct administration rates were better for patient-based medication schedules (85.6%) than with hospital-based schedules (77.5%), but did not achieve statistical significance. Conclusion: Adherence to regular PD medication dosing schedules during hospitalization is problematic, but improves with specialist consultation. Staff involved in the admission process for PD patients should work to safeguard against disruption of the prescribed home dosing schedule.
