Early detection of patient deterioration remains an elusive patient safety target. This scoping review examined how nurses employ early warning scoring systems that prompt them to call rapid response teams. Investigators identified 23 studies for inclusion. Barriers to effective identification and treatment of patient deterioration included difficulty implementing early warning score systems, overreliance on numeric risk scores, and inconsistent activation of rapid response teams based on early warning score results. They recommend that nurses follow scoring algorithms that calculate risk for deterioration while supplementing risk scoring with their clinical judgment from the bedside. A WebM&M commentary highlighted how early recognition of patient deterioration requires not only medical expertise but also collaboration and communication among providers.
