Improving evidence-based care in cystic fibrosis through quality improvement.

OBJECTIVE: To increase clinician adherence to prescribing guidelines for pulmonary medications in children with cystic fibrosis (CF).

DESIGN: Quality improvement project with multiple time series design.

SETTING: The CF center at a tertiary care pediatric hospital in the United States.

PATIENTS: Children with CF who were eligible to receive oral azithromycin, nebulized dornase alfa, or inhaled tobramycin sulfate based on prescribing guidelines for CF lung disease.

INTERVENTION: Evidence-based prescribing guidelines were designed by a local committee to reflect consensus recommendations from the CF Foundation. Clinicians and families were educated about guidelines. Adherence to prescribing guidelines was tracked using a local CF database and record reviews. Weekly meetings were used to highlight adherence failures and promote clinician accountability.

MAIN OUTCOME MEASURE: The rate of clinician adherence to prescribing guidelines.

RESULTS: One hundred seventy patients with CF were included. At the start of the project, the rate of clinician adherence to prescribing guidelines was 62%. After 3 months of the project, the rate of clinician adherence to prescribing guidelines was 87% (odds ratio = 4.6; 95% confidence interval, 3.0-7.0). The improvements in adherence to prescribing guidelines were sustained for 21 months of follow-up.

CONCLUSIONS: Educating clinicians about prescribing guidelines, sharing guidelines with families, and monitoring clinician adherence improve prescribing adherence to evidence-based recommendations.
