A discrete choice experiment assesses treatment preferences in advanced Parkinson’s disease, suggesting improved decision-making is needed.

The study aims to identify treatment preferences among individuals with advanced Parkinson’s disease and their care partners.
Conducted a discrete choice experiment with 304 participants (223 PwP, 81 CPs) from the USA, UK, and Germany.
Presented choice tasks featuring hypothetical treatments defined by seven attributes.
Used a random parameter logit model to analyze the data and determine attribute importance.
Route of administration (ROA) and hours of ON time without troublesome dyskinesia (ONwoTD) were the most valued attributes.
Participants showed a strong preference for nonsurgical treatments, particularly oral medication.
Understanding these preferences can improve treatment decisions between patients and healthcare providers.

Arija et al. (2026) studied this question.
