Medical emergency teams (MET), also known as rapid response teams, are used to improve the identification and management of patients demonstrating signs of rapid deterioration. This study found that modifying activation criteria to trigger METs at more extreme levels of clinical deterioration were not associated with negative patient safety outcomes.

Isolation for infection prevention and control is beneficial but may result in unintended consequences for patients (e.g., less attention, suboptimal documentation and communication, higher risk of preventable adverse events). This systematic review did not identify any evidence suggesting that adult patients in isolation precautions for infection control are more likely to experience clinical deterioration or hospital-acquired complications compared to non-insolated patients.

Rapid response systems, though controversial, have been widely implemented in acute care settings, but not emergency departments. In this pre-post study, rapid response implementation in an emergency department was associated with improved recognition of clinical deterioration, but investigators were not able to detect changes in patient outcomes. With these results, the data on rapid response systems remains inconclusive and suggests the need for more robust post-implementation data on effectiveness and costs.
