Implementation of a β-agonist/airway clearance protocol in a pediatric ICU

Abstract

BACKGROUND: Respiratory therapist (RT)-driven protocols have been in use for over 30 years. Protocols have been reported to decrease unnecessary or harmful therapy, health-care costs, and hospital stay. This study represents the evaluation of an original respiratory care protocol in the pediatric ICU at Arkansas Children’s Hospital for β-agonist and airway clearance interventions where one did not exist. METHODS: This project was composed of 2 parts: a survey administered to RTs and licensed independent practitioners and a retrospective review of outcome data comparing a therapist-driven β-agonist/airway clearance protocol with physician-directed respiratory care ordering in a patient population admitted for acute respiratory failure. RESULTS: Acceptance of the protocol was evident in the survey responses because overall perceptions surrounding the implementation of the β-agonist/airway clearance protocol were positive, and responders perceived that the protocol implementation elevated the status and increased the value of respiratory therapists. For the comparison of physician-directed orders with therapist-driven protocols, there were no significant differences between pre- and post-intervention groups for mean age, sex, mean daily acuity, or mean weighted daily acuity (P =. 33,. 19, >.99, and. 79, respectively). There were also no differences in pediatric index of mortality 2, pediatric index of mortality 2 rate of mortality, pediatric risk of mortality 3 probability of death, and pediatric risk of mortality 3 scores (P =. 63,. 56,. 19, and. 44, respectively) between the 2 groups. When comparing physician-directed orders to therapist-driven protocols, all outcome measures (length of stay, β-agonist therapies, airway clearance therapies, and ventilator days) showed statistically and clinically important reductions, adjusting for subject characteristics (P
