Learning Objective 1: The learner will be able to discuss the reliability testing of an adapted evidence-based Modified Early Warning Scoring (MEWS) tool.
Learning Objective 2: The learner will be able to discuss Modified Early Warning Scoring (MEWS) tool reliability testing results with implication to nursing practice.
Methods: Reliability testing of a developed MEWS tool in a mock hospital low-fidelity simulation setting with clinical data from septic hospitalized patients was used.
Results: Reliability between total scores in each MEWS color in the simulated scenarios ranged from Green 88%, Yellow 92%, Orange 72%, and Red 76%. Analysis of the research question from a convenience sample of (n=25) nurses indicate the entire MEWS tool had a Cronbach’s alpha level of 0.76.
Conclusion: The reliability results are acceptable. Variance in results between the scenarios suggests that further education may be needed as patient complexity increases. The ultimate goal for the research team includes assurance that evidence-based practice measures are incorporated into the MEWS tool physiological assessment findings and associated algorithms to identify the at-risk for deterioration patient earlier, thus positively impacting mortality.
