Scoping review assesses evidence quality of digital health apps in Germany, highlighting significant limitations.

The aim is to evaluate the quality of evidence regarding Digital Health Applications (DiGAs) in Germany.
Conducted a scoping review following PRISMA-ScR guidelines.
Included studies published between 2020 and 2024 that assessed DiGA evaluation tools and study quality.
Screened 4628 publications, resulting in 16 relevant studies being included.
Identified major deficits in evidence quality dimensions: validity (9 publications), transparency (7), objectivity (6), consistency (5), and reliability (5).
Significant issues of dropout rates, lack of blinding, gender imbalance, high risk of bias, and small sample sizes noted.
Usage of DiGAs often shorter than recommended, indicating need for better evaluation pathways.

Zapp et al. (2026) studied this question.
