NAPLES, Fla. — A medication self-confidence questionnaire could help physicians identify which glaucoma patients need assistance with drop instillation and specific barriers to adherence, a study found.
"The 14-item self-efficacy in carrying out specific tasks required to use eye drops correctly scale can be used by eye care providers to screen for whether patients report a lack of confidence in certain aspects of using their eye drops (eg, getting the drop of medication in the eye, squeezing the eye drop bottle)," Alan L. Robin, MD, and colleagues said at the American Glaucoma Society meeting.
In a poster study, they presented results of 104 non-naïve subjects who took the validated Glaucoma Medication Self-Efficacy (or Self-Confidence) Questionnaire and were video recorded for drop instillation technique. The questionnaire is divided into two subscales, examining barriers to medication use and drop utilization.
The study found that subjects with higher scores for eye drop utilization questions were significantly more likely to "make one attempt to instill the drop (P = .003) and to succeed in this effort (P = .02)."
