The previously validated (indications: atrial fibrillation, human immunodeficiency virus, chronic inflammatory lung disease) Adherence Barriers Questionnaire (ABQ) was revised according to specifications of IVT, within the framework of an expert panel. A cross-sectional patient survey was conducted in combination with a retrospective medical chart review in order to validate the developed new instrument (ABQ-IVT).

The aim of this investigation was to develop and validate a respective questionnaire (Adherence Barriers Questionnaire for HIV: ABQ-HIV), based on an earlier version of the ABQ.

The study showed that the ABQ-HIV is a practical, reliable, and valid instrument for identifying patient-specific barriers to

adherence in the HIV treatment that is also useful in identifying HIV patient subgroups.

The aim of this study was to assess patients’ views and xpectations with regard to neovascular age-related macular degeneration (nAMD) and intravitreal anti-VEGF therapy (IVT).

This multicenter, non-interventional, prospective cohort study showed that only a minority of patients are aware of the chronic nature of nAMD. To motivate patients to accept a life-long IVT treatment, physicians and caregivers must know that there exist different patient types with significant differences in communication needs.
