Modifiable Determinants of Satisfaction with Intravitreal Treatment in Patients with Neovascular Age-Related Macular Degeneration.

ABSTRACT

BACKGROUND: The success of intravitreal treatment for neovascular age-related macular degeneration (nAMD) depends on maximal adherence to treatment, which in turn requires patient satisfaction. OBJECTIVE: The aim of this study was to assess the factors associated with nAMD patient satisfaction to implement actions to improve treatment experiences and increase adherence. DESIGN: This was a prospective, observational, analytical, cross-sectional study. SUBJECTS: Our study included 100 consecutive nAMD patients under intravitreal treatment for at least 1 year. METHODS: Patients completed the Macular Disease Treatment Satisfaction Questionnaire (MacTSQ) and the EuroQol Visual Analog Scale (EQ VAS). A logistic regression was estimated to model the low values of the satisfaction score (MacTSQ < 50). RESULTS: The mean age of patients was 82.1 ± 7.8 years and 62% were female. Males (p = 0.002) and patients who improved their visual acuity (p = 0.004) were more satisfied, while patients who received a higher number of injections (p = 0.036) and treatment in both eyes (p = 0.001) were less satisfied. Higher health-related quality of life was related to higher satisfaction. The sensitivity and specificity of the predictive model were 75.8% and 76.1%, respectively. Factors independently associated with low satisfaction were female sex (odds ratio [OR] 6.84), going to the clinic alone (OR 8.51), longer duration of treatment (OR 0.62), receiving treatment in both eyes (OR 3.54), and suffering a decline in visual acuity (OR 3.30). The questionnaire revealed patients' needs for more information and injection points closer to their homes. CONCLUSIONS: Well-defined areas for improvement were identified, i.e. to improve the information offered to each patient, to incorporate new long-acting drugs, and to establish locations for injection services in peripheral areas.
