Although reflecting patient preferences in treatment decision-making is desirable, few studies have examined this in Japan. This study assessed the patients willingness to trade-off between different dosing regimens.Patients and Methods: Patients with wAMD were recruited from four Japanese university hospitals to complete a face-to-face cross-sectional survey. In a discrete choice experiment, patients were asked to choose their preferred option from two anti-VEGF treatment profiles shown side-by-side across a series of choice tasks. The profiles varied on four attributes: number of injections in 12 months, number of physician consultations in 12 months, chance of 1-year visual acuity (VA) improvement, and chance of 2-year VA maintenance. Preference weights were estimated using hierarchical Bayes’ models.Results: Overall, 120 patients (30 treatment naïve and 90 anti-VEGF experienced) completed the survey. Patients were willing to accept an increase from three to approximately eight injections in 12 months to increase the chance of 1-year VA improvement from 25% to 40%. They would be willing to accept 11 injections in 12 months if the chance of 2-year VA maintenance increased from 80% to 96%. The most valued attributes were increasing the chance of 2-year VA maintenance and reducing the number of injections in 12 months, which were each about twice as important as decreasing physician consultations in 12 months and increasing the chance of 1-year VA improvement (p< 0.001). Among the dosing regimens, patients most preferred treat-and-extend because of its higher chance of 2-year VA maintenance.Conclusion: Informing patients with wAMD about the likelihood of long-term VA maintenance when selecting treatment may increase the acceptance of an optimal treatment regimen and number of injections.Keywords: wet age-related macular degeneration, patient preference, anti-vascular endothelial growth factor treatment, dosing regimen, treat-and-extendhttps://www.dovepress.com/patient-preferences-for-anti-vascular-endothelial-growth-factor-treatm-peer-reviewed-article-PPAwet age-related macular degenerationpatient preferenceanti-vascular endothelial growth factor treatmentdosing regimentreat-and-extendevery two-month dosingpro re nata. |
