RESUMO
Background: Parkinson's disease (PD) is the second most common neurodegenerative disease with a lifetime risk of 1% to 3%. Treatment includes supplementation of central dopaminergic neurotransmission with levodopa preparations and dopamine agonists. Misprescribing and delayed administration of these medications on admission to hospital can result in increased morbidity and mortality. Objective: We aimed to assess the accuracy of time-critical PD medication prescribing and administration during unplanned hospital admissions. Methods: Patients admitted during a 15-month period with PD on time-critical PD medications were included. Their electronic patient records were compared with the pharmacist medication reconciliation to assess accuracy of admission prescribing. Accuracy of administration was assessed by comparing the time medications were administered to the time they were due. Statistical Package for Social Sciences software was used to perform statistical analysis in this study. Results: A total of 102 admissions of 70 patients (67% men) were included for analysis. These patients were on 1.6 ± 0.8 time-critical PD medications before admission, accounting for 4.1 ± 1.8 administrations per day. Time-critical medications were prescribed correctly on admission in 50% of admissions, with errors in medication timing most common (31.6%). Of all doses, 51.7% were administered >30 minutes late, and 29.7% of doses were administered >1 hour late. Female sex, a higher number of medications, and more frequent administrations were significantly associated with the rate of medication error. Conclusion: This study demonstrates high rates of inaccurate prescribing and inaccurate administration of time-sensitive medication in a cohort of patients with PD admitted acutely to hospitals.
