In August 2017, Collins and colleagues published the results of a decision analysis simulation model in Hospital Pediatrics titled “High-Flow Nasal Cannula in Bronchiolitis: Modeling the Economic Effects of a Ward-Based Protocol.” The analysis was based on data from Seattle Children’s Hospital and included 1,432 patients under the age of 2 who had a diagnosis of bronchiolitis without any major comorbidities and the results suggest that use of HFNC on wards may be cost effective and may reduce patient length of stay for this patient population.
The model simulated an option in which high flow nasal cannula (HFNC) was used on the ward and one in which HFNC was used in the ICU and had the following results:
|Ward HFNC||ICU HFNC|
|Average Admission Cost||$7020|
(95% CI $6840 – $7194)
(95% CI $7427–$7839)
|Average Length of Stay||2.29 days|
(95% CI 2.24–2.33)
(95% CI 2.56–2.66)
The net differences of the results showed that the ICU HFNC option averaged $606 (95% CI $408–$795) more and 0.32 days (95% CI 0.27–0.37) more than the Ward HFNC.
The researchers note that a partial rationale for the microsimulation decision analysis was to evaluate their hospital’s decision to implement HFNC and develop a standardized pathway for its use. Although the study focused on economic outcomes, its premise was that HFNC had been used safely on the floor in patients with bronchiolitis. The standardized pathway followed at Seattle Children’s was developed to help providers in using the technology safely.
Collins and colleagues state that increased flow rates with HFNC could be an additional way to reduce ICU admissions for bronchiolitis patients.
