In 2025 the doctors of the Medizinischer Dienst, the medical review service, wrote 11,735 expert reports on suspected treatment errors across Germany. In every fourth case, 3,098 in all, they found an error that had caused harm. In 97 cases the error led to death or contributed substantially to it.
When it presented the figures in August 2026, the service called for a mandatory, pseudonymized and sanction-free reporting system for so-called never events.
