We aimed to investigate the incidence of medication mismanagement in hospitalized PD patients at GWUH and explore the potential relationship of medication mismanagement on lengths of stay, 30-day readmission rates, falls, and delirium.
Parkinson’s disease (PD) requires complex medication management. Medication errors involving mistimed PD medications or the use of contraindicated medications are common in hospitalized PD patients.3 Medication mistiming is associated with longer lengths of stay and more complications.2 However, limited data exists examining the relationship of contraindicated medications on hospital outcomes in the PD population.4
A retrospective chart review of 377 PD patients was performed. Lengths of stay, 30-day readmission rates, falls, and delirium incidences among PD patients were compared to matched controls. In the PD cohort, medication errors were defined as mistimed PD medication administration by more than 30 minutes or use of contraindicated medications. Statistical analyses were performed to determine whether medication errors were associated with lengths of stay, 30-day readmission rates, falls, and delirium.
Compared to controls, PD patients had approximately doubled lengths of stay (p<0.001), 30-day readmission rates (p<0.001), and delirium incidences (p=0.009). No differences were observed between PD and control cohorts regarding falls (p=0.320). Medication timing errors occurred in 88.1% of PD patients. 14% of PD patients were prescribed a contraindicated medication, and those patients experienced significantly longer lengths of stay (p<0.001) and significantly more delirium incidences (p=0.001). No statistically significant differences were observed in 30-day readmission rates (p=0.248) or falls (p=0.408).
Medication mismanagement of PD patients is prevalent, and the use of contraindicated medications is associated with longer lengths of stay and higher delirium incidents. This supports several reports in the literature regarding the frequency and potential impact of medication mismanagement of hospitalized PD patients1-5 and is an important step in recognizing and addressing the quality of care hospitalized PD patients receive.
