What side effects of dry eye treatment are most important to patients?
Researchers utilized a Discrete Choice Experiment to determine which factors are important to patients with dry eye disease (DED) when choosing medications to potentially improve adherence.
Patients diagnosed with DED (n = 139) were given 10 choice tasks where they were asked to choose between their current medication (or no medication), and 2 hypothetical medications that varied based on 5 attributes, including duration of burning/stinging, duration of blurring, time to medication effectiveness, medication frequency, and out-of-pocket cost.
There were 2 groups with distinct preferences. The duration of burning/stinging and cost were the most important attributes for both groups whereas the duration of blurring was the least important.
There was an 18 percentage-point increase in predicted uptake of a medication when the duration of burning/stinging decreased to a few minutes from 2 hours.
“Predicted uptake for new medications was lowest for those on medication with well-controlled symptoms and highest for those who were not on medication and could not control their symptoms effectively,” the authors wrote.
