Reduction in hospital mortality over time in a hospital without a pediatric medical emergency team: limitations of before-and-after study designs.
Approach to Improving Safety
Setting of Care
Rapid response systems (RRS) have been widely adopted despite mixed results about their impact in both pediatric and adult settings. This study found a reduction in hospital mortality without a pediatric medical emergency team (PMET). The authors use their findings to illustrate the limitations of before-and-after study designs that previously demonstrated benefits of RRS. These reported benefits in pediatric settings may have resulted from any number of cointerventions rather than adoption of a PMET itself. An accompanying editorial [see link below] further advocates for investments in well-performed studies that can be cost-effective, and appropriately align limited resources to the most proven interventions.
