Implementation of a Critical Asthma Protocol in a Pediatric ICU

Area of Science:

• Pediatric Critical Care Medicine
• Respiratory Medicine
• Clinical Protocol Implementation

Background:

• Variability exists in pediatric intensive care unit (ICU) management for critical asthma.
• Provider-dependent approaches contrast with successful protocol-driven therapy on general pediatric wards.
• A standardized protocol was investigated to improve clinical outcomes in critical asthma.

Purpose of the Study:

• To evaluate the effectiveness of a standardized treatment protocol for critical asthma in a pediatric ICU.
• To determine if protocol implementation could lead to improved clinical outcomes, including reduced albuterol use and length of stay.
• To assess adherence rates to the standardized critical asthma protocol.

Main Methods:

• A pre-intervention cohort (n=52) and a post-intervention cohort (n=71) of pediatric patients (age 2-18) with critical asthma were compared.
• Data on demographics and medication administration were collected via electronic medical records.
• The primary endpoint was time on continuous albuterol; secondary endpoints included ICU and hospital length of stay (LOS).

Main Results:

• No significant differences in demographics between pre- and post-intervention cohorts.
• Overall protocol adherence was 42%.
• Protocol adherence was associated with significant reductions in time on continuous albuterol (14.4h vs 3.0h, P < .001), ICU LOS (38.7h vs 21.0h, P < .001), and hospital LOS (2.8d vs 1.7d, P = .005).

Conclusions:

• The standardized asthma protocol did not yield significant improvements in the overall cohort, likely due to low adherence.
• Protocol-adherent subjects demonstrated significant improvements in key outcome measures.
• Low adherence remains a barrier to successful protocol implementation in critical asthma management.
