Abstract
PURPOSE: This survey was conducted to identify factors that influence how patients with neovascular age-related macular degeneration (nAMD) deal with their disease and information that are considered useful from a patient's point of view. METHODS: A total of 5035 patients with nAMD living in Germany were interviewed via internet-based cross-sectional survey, where the following information was collected: personal data, disease awareness, and patients' needs. In addition, a Quality of Life questionnaire (SF-12v2) could be completed. RESULTS: Out of the 5035 participants, more males than females participated (55% vs 45%), and most participants were in the age groups 76 to 85 years (37%) and 66 to 75 years (35%). Seventy-three percent of patients rated their understanding of the disease as at least sufficient, and more than two-thirds of the patients (68%) were aware that their disease needs to be controlled on a regular basis and treated on an "as needed" basis. Regarding potential risk factors for AMD, most participants were aware of age (89%), but only 39% of hereditary load and 33% of smoking as evidence-based risk factors, indicating a need for further information. The doctor remains the major source of information (93%), with internet (29%), brochures (14%), opticians (13%), or patient support groups (4%) with only limited contribution. Distance to the treatment center was identified as one of the factors, which had the greatest influence on patients' compliance. A "treat as needed" regime turned out to be the preferred control and treatment schedule in contrast to a "fixed appointment" every 4 weeks. CONCLUSION: This internet-based survey appears to be representative for nAMD patients. To increase patients' compliance, proximity to the treatment center and a "treat as needed" regime turned out to be important factors as well as patients' awareness of their disease. In this regard, the reported desire for more information indicates that patients' knowledge still needs to be improved. Our results will help to further optimize patient care and patient-oriented information.
