Evaluation of an evidence-based guideline for bronchiolitis

Objective. To describe the effect of implementing an evidence-based clinica l practice guideline for the inpatient care of infants with bronchiolitis a t the Children's Hospital Medical Center in Cincinnati, Ohio. Methodology. A multidisciplinary team generated the guideline for infants l ess than or equal to 1 year old who were admitted to the hospital with a fi rst-time episode of typical bronchiolitis. The guideline was implemented Ja nuary 15, 1997, and data on all patients admitted with bronchiolitis from t hat date through March 27, 1997, were compared with data on similar patient s admitted in the same periods in the years 1993 through 1996. Data were ex tracted from hospital charts and clinical and financial databases. They inc luded LOS and use and costs of resources ancillary to bed occupancy. Results. After implementation of the guideline, admissions decreased 29% an d mean LOS decreased 17%. Nasopharyngeal washings for respiratory syncytial virus were obtained in 52% fewer patients. Twenty percent fewer chest radi ographs were ordered. There were significant reductions in the use of all r espiratory therapies, with a 30% decrease in the use of at least 1 beta-ago nist inhalation therapy. In addition, 51% fewer repeated inhalations were a dministered. Mean costs for all resources ancillary to bed occupancy decrea sed 37%. Mean costs for respiratory care services decreased 77%. Conclusions. An evidence-based clinical practice guideline for managing bro nchiolitis was highly successful in modifying care during its first year of implementation.
