Rapid response teams health care

Rapid response teams (RRT) are teams of health care providers that respond to hospitalized patients with signs of deterioration in non-intensive care units to prevent respiratory or cardiac arrest. You are interested in evaluating whether the presence of a Rapid Response Team reduces mortality due to sudden cardiac arrest. For your evaluation, you compare data gathered in 2016 from two similar hospitals, one with and one without a Rapid Response Team. Select the evaluation study design that this best describes:

Combination design

Randomized design

Before-after design

Simultaneous non-randomized design
