A residency program introduces a sepsis checklist intervention across 10 hospitals, with each site randomly assigned a staggered implementation month over 12 months. Baseline sepsis mortality rates averaged 18-22% across sites. Outcomes including 30-day mortality, lactate clearance within 6 hours, and time-to-antibiotics are measured continuously before and after implementation at each hospital. No concurrent interventions were introduced. Which trial design is being used?
- A)Factorial trial
- B)Cross over trial
- C)Stepped wedge trialGABARITO
- D)Case control study
- E)Cluster randomized parallel trial
Explicação
A stepped wedge trial is a cluster design in which all clusters eventually receive the intervention, but rollout occurs in randomized sequence over time. Continuous measurement before and after adoption allows each site to contribute control and intervention p... Ver explicação completa e trilha adaptativa →
