Treatment contentment and preference of patients undergoing intravitreal anti-VEGF therapy.

purposeThe aim of this study is to investigate patients´ treatment preference between the pro re nata (PRN) and treat and extend (T&E) regimens and their feelings and contentment undergoing intravitreal injections (IVI) with anti-vascular endothelial growth factor (anti-VEGF) agents.

methodsSix months after the switch of the treatment regimen from PRN to T&E, answers of a 16-item questionnaire of 105 patients under IVI therapy regarding age, sex and treatment preference (T&E or PRN regimen), as well as burden and anxiety resulting from therapy, were evaluated. Analysis of associations between answers of the questionnaire was executed using Pearson's Chi

resultsNearly all patients (90.5%) felt well informed about disease and therapy. Comparing treatment regimen, 13.7% thought PRN was better and 23.3% felt T&E was better. The majority considered PRN and T&E to be equal (60.3%). No significant association between treatment regimen and age (p = 0.15), gender (p = 0.35) and duration of IVI therapy (p = 0.42) was seen. The examination results are associated with fear in the majority of patients (53.3%). Fear about the IVI was indicated by 47.6% of individuals and was significantly associated with pain during treatment (p = 0.0003), pain after treatment (p = 0.004) and fear about unfavourable examination results regarding disease activity (p = 7.94 × 10

conclusionsMost patients are satisfied with the IVI therapy and the treatment regimen. Fear of the IVI and particularly of unfavourable examination results demonstrate the high treatment burden for patients undergoing anti-VEGF therapy. These aspects should be taken into account by healthcare professionals.
