Insights
Evidence-based standardized protocols (EBSPs) for childhood asthma in emergency departments did not reduce hospital admissions or return visits. Further research is needed to link asthma care processes with improved patient outcomes.
Area of Science:
- Pediatric Emergency Medicine
- Respiratory Health
- Healthcare Quality Improvement
Background:
- Standardized protocols are increasingly used in healthcare to improve patient outcomes.
- Evidence-based standardized protocols (EBSPs) aim to standardize care for conditions like childhood asthma.
Purpose of the Study:
- To evaluate the impact of EBSPs on hospital admission rates, emergency department (ED) return visits, and outpatient follow-up for children with asthma in Ontario, Canada.
Main Methods:
- Retrospective population-based cohort study involving 146 emergency departments in Ontario.
- Analysis of 31,138 children (aged 2-17 years) with asthma treated between April 2006 and March 2009.
- Multivariable logistic regression used to compare outcomes between children treated with EBSPs, other standardized protocols, or no protocols.
Main Results:
- The study analyzed 46,510 ED visits for childhood asthma.
- Evidence-based standardized protocols (EBSPs) were not associated with significant differences in hospital admissions (aOR 1.17), 7-day ED return visits (aOR 1.10), or 7-day outpatient follow-up (aOR 1.08).
Conclusions:
- The implementation of EBSPs in emergency departments for childhood asthma did not lead to improved rates of hospital admission, ED return visits, or follow-up.
- Findings highlight a need to identify and address the disconnect between asthma care processes and clinical outcomes.
Objective:
To determine whether children treated in emergency departments (EDs) with evidence-based standardized protocols (EBSPs) containing evidence-based content and format had lower risk of hospital admission or ED return visit and greater follow-up than children treated in EDs with no standardized protocols in Ontario, Canada.
Design:
Retrospective population-based cohort study of children with asthma. We used multivariable logistic regression to estimate risk of outcomes.
Setting:
All EDs in Ontario (N = 146) treating childhood asthma from April 2006 to March 2009.
Participants:
Thirty-one thousand one hundred thirty-eight children (aged 2 to 17 years) with asthma. MAIN EXPOSURE Type of standardized protocol (EBSPs, other standardized protocols, or none).
Main Outcome Measures:
Hospital admission, high-acuity 7-day return visit to the ED, and 7-day outpatient follow-up visit. RESULTS The final cohort made 46 510 ED visits in 146 EDs. From the index ED visit, 4211 (9.1%) were admitted to the hospital. Of those discharged, 1778 (4.2%) and 7350 (17.4%) had ED return visits and outpatient follow-up visits, respectively. The EBSPs were not associated with hospitalizations, return visits, or follow-up (adjusted odds ratio, 1.17 [95% CI, 0.91-1.49]; adjusted odds ratio, 1.10 [95% CI, 0.86-1.41]; and adjusted odds ratio, 1.08 [95% CI, 0.87-1.35], respectively).
Conclusions:
The EBSPs were not associated with improvements in rates of hospital admissions, return visits to the ED, or follow-up. Our findings suggest the need to address gaps linking improved processes of asthma care with outcomes.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
