Parkinson's Disease Medication Administration Timing Deviations and Contraindicated Medicine Use in Residential Aged Care: A Retrospective Cohort Study

Parkinson's disease (PD) is a common condition among older people and requires tailored, time-sensitive pharmacologic therapy for optimal symptom management. No prior studies have examined the extent to which doses of time-critical PD medicines are delayed or missed in residential aged care (RAC) settings. We aimed to identify deviations in PD medication administration timing and the use of medicines that are contraindicated in PD.
