Safe and Effective Use of Score-Based Continuous Albuterol Therapy in a Pathway for Treatment of Pediatric Asthma Exacerbation.

BACKGROUND

Standardized acute asthma management with score-based, respiratory therapist (RT)-driven pathways and protocols improves outcomes including decreased length of stay (LOS) and time on continuous albuterol therapy. Limited data are available for the safety of continuous albuterol used outside of pediatric ICU (PICU). We use a modified pediatric asthma score (PAS) for the asthma pathway at our institution. The safety and effectiveness of using PAS to initiate/stop continuous albuterol as part of a score-based, RT-driven asthma pathway were evaluated.

METHODS

A retrospective review of children ≥ 2 y admitted for asthma exacerbation to the PICU and step-down unit who received continuous albuterol as part of the asthma pathway during 2017-2019 was completed. Demographic and clinical data were extracted including PAS, dose and duration of continuous albuterol, LOS, and complications. Outcomes of subjects admitted to the PICU and step-down unit were compared.

RESULTS

Results are expressed as median (interquartile range). The study included 412 children (61% male, 59.9% Black, 92.7% non-Hispanic, 44.9% moderate persistent asthma) with age and weight of 6.4 (4.0-10.0) y and 24.8 (17.3-39.5) kg, respectively. Most children were admitted to step-down unit (71.1%). Initial albuterol dose, duration, and LOS were 15 (10-20) mg/h, 9.1 (5.7-16.0) h, and 1.4 (0.9-2.3) d, respectively. Respiratory support was required by 29% of subjects. Need to restart therapy (2.9%), transfer to PICU (1.7%), and intubation (0.5%) were infrequent. No pneumothoraces or deaths were reported. Emergency department visits (3.9%) or readmissions (0.7%) within 30 d of discharge were low. Subjects admitted to the PICU were sicker and required more therapies and respiratory support than those admitted to the step-down unit.

CONCLUSIONS

Use of an RT-driven, score-based pathway for initiation and discontinuation of continuous albuterol for treatment of pediatric asthma exacerbation was safe and effective in the PICU and step-down unit.
