This study's main objective is to determine the effect of a nursing-driven clinical pathway on children's length of stay when admitted to hospital with a diagnosis of acute asthma exacerbation. The pathway will allow nurses to wean a specific type of medication(β2-agonist), as compared to the current standard of care, which dictates that a physician writes an order to wean the medication. Number of administered β2-agonist treatments will be compared between both groups, as well as asthma-related health care utilization within two weeks of hospital discharge. Nursing, physician, and patients' satisfaction with the pathway will be evaluated, and a cost minimization analysis will be performed.
