Abstract
INTRODUCTION: Parkinson's disease (PD) is considered to be the fastest growing neurological disorder in the world. Patients with PD are hospitalised more frequently, have longer admissions and experience more complications during hospitalisation than age-matched control groups. The incorrect timing of levodopa administration and prescription of contraindicated antidopaminergic drugs are the most important risk factors for motor function deterioration during hospital admission, and have been associated with longer hospital stays and even increased mortality. Despite their crucial role in pharmacotherapy, little attention has been paid to the perspective of hospital pharmacists. The objective of this study was to identify key issues in the pharmacotherapeutic management of inpatients with PD by the implementation of a national Spanish survey specifically designed to analyse the perspective of hospital pharmacists. METHODS: An internet-based questionnaire covering the following areas was designed: hospital and participant characteristics, drug formulary, medication compliance and reconciliation, protocols and contraindicated drugs and areas for improvement. RESULTS: A total of 76 pharmacists from 59 hospitals answered the survey. Some weaknesses were identified in the availability of drugs: (1) pharmacy services closed at certain times (86.4%); (2) low variety of antiparkinsonian drugs (18.4% store >21 different drugs); (3) delay in antiparkinsonian drug administration if unavailable (>12 hours in 39.5% of cases); (4) lack of flexibility in administration times; (5) low availability of transdermal rotigotine and subcutaneous apomorphine (<50%). The participants ranked highly the designing of specific protocols for patients with PD and implementation of concrete actions to optimise PD inpatient pharmacotherapy. CONCLUSIONS: The participants detected some improvement opportunities and proposed realistic and applicable recommendations and strategies aiming to enhance the safety of patients with PD. Protocols for antiparkinsonian drug interchange, administration timing and nil by mouth status, medication reconciliation, and handling nausea/vomiting or psychotic symptoms are considered the main improvement areas.
