Research for infection protection

Infection Control Standards

Hygiene and infection control measures that are scientifically sound and, if possible, confirmed by different disciplines, are the gold standard in infection protection. Comprehensive, scientifically validated findings are the basis for developing and implementing standards to ensure a consistent, accepted approach for minimising infection risks. In recent years, new findings have led to new standards and have optimised hygiene.

To assess infection control recommendations and standards, the following international ranking system for evidence has been established:

Evidence levels of recommendations*

Category I A:
Strongly recommended for implementation and strongly supported by well-designed experimental, epidemiological, or clinical studies.

Category I B:

Strongly recommended for implementation and supported by at least one experimental, epidemiological, or clinical study or by a strong theoretical rationale.

Category I C:
Required for implementation, as mandated by legal provisions, administrative provisions or standards.

Category II:
Suggested for implementation and supported by suggestive clinical or epidemiological studies or a theoretical rationale or a consensus by a panel of experts.
