Purpose: A decision aid facilitates patient engagement in the decision-making process in ophthalmic practice. In particular, patients with open-angle glaucoma will benefit from such an intervention as it enhances their knowledge, compliance, and satisfaction with the healthcare services.
Methods: The Encounter Glaucoma Decision Aid (GDA) was delivered to 145 patients with open-angle glaucoma at the King Khaled Eye Specialist Hospital. Evaluation was done using a pre-validated, semi-structured questionnaire. We compared the patients' knowledge, compliance, and decision conflict scale at baseline, before receiving Encounter GDA, and again three months later.
Results: The average age of the participants was 56.82 years. Most of the participants were male (67.6%). The mean duration since the participants were diagnosed with glaucoma was 9.39 years. After using Encounter GDA, 80% of participants had a statistically significant improvement in their level of knowledge, moving from poor to good (P = 0.001). There was also a statistically significant increase in adherence to medication, from 41.4% to 65.5% (P = 0.001). The decision conflict score decreased significantly after using Encounter GDA (before it was 60.94 ± 21.60 vs. after 19.18 ± 17.83).
Conclusion: Using GDA cards as an educational measure has a significant effect on improving patient's knowledge and adherence to medications.
