What Evidence is Available on Rapid Response Systems Across Europe? Findings From a Scoping Review.

PMID 41131880WHAT IT FOUND
European rapid response teams vary widely in structure and activation.
While some studies report reduced cardiac arrests and mortality, others show no significant difference or increased ICU transfers. There is no single standard model, and evidence of consistent patient benefit is limited by heterogeneous study designs.
Key findings
01Rapid response teams in Europe are highly variable in their composition, availability, and activation criteria, with no standardised approach.
02Patient outcomes were inconsistent: some studies reported reductions in cardiac arrests and mortality, while others found no significant difference in mortality.
03The majority of included studies were descriptive or cross-sectional, focusing on team characteristics rather than testing effectiveness against a control.

What it does not show
The review is a scoping review, not a systematic review with meta-analysis, so it does not provide a pooled estimate of effect. Most included studies were descriptive or cross-sectional, limiting the ability to infer causality between RRS implementation and patient outcomes. There was significant heterogeneity in how outcomes were measured and reported across studies. Only English-language studies were included, which may have missed relevant research from other European countries. Eastern European countries were under-represented in the included studies.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that implementing a rapid response system will automatically reduce mortality or cardiac arrests in your hospital. The evidence is mixed, with some studies showing no significant benefit, and outcomes depend heavily on local implementation, team composition, and activation criteria.
