Measuring how common neovascular AMD, diabetic macular edema, and retinal vein occlusion are in Germany using health insurance data

DATA-INSIGHT: Data Analysis for Treatment Assessment and Evaluation of New Sources for Evidence Generation in German Healthcare System

Observational Bayer · NCT07308639

This project will use two large German health databases from 2009–2024 to find out how often people with nAMD, DME, or RVO are diagnosed and how many people currently have these conditions in Germany.

What this trial studies

This observational analysis uses anonymized insurance records from two nationwide German datasets (FDZ and FDGP) covering 2009–2024 to estimate incidence and prevalence of nAMD, DME, and RVO. Researchers will identify patients with at least one relevant diagnosis code and compare counts, rates, and temporal trends between the two data sources. The work will apply age criteria (nAMD ≥50 years; DME and RVO ≥18 years) and will capture markers of care such as recorded anti-VEGF medication use when available. The project will also examine methodological differences between FDZ and FDGP to understand how data collection and coding affect disease estimates.

Who should consider this trial

Good fit: Included records represent German residents with statutory or private health insurance who have at least one recorded diagnosis of nAMD (age ≥50) or DME/RVO (age ≥18) between 2009 and 2024.

Not a fit: People without diagnoses recorded in FDZ or FDGP, residents outside Germany, or those whose care falls outside the 2009–2024 timeframe will not be represented and are unlikely to benefit directly from this analysis.

Why it matters

Potential benefit: If successful, the results could help clinicians and health planners better understand disease burden and target resources and treatments where they are most needed.

How similar studies have performed: Previous large administrative-database studies have produced useful incidence and prevalence estimates for these retinal diseases, but direct side-by-side comparisons of two national German datasets are less common and add a novel methodological angle.
