Insights
Implementing a standardized pediatric asthma clinical practice guideline (CPG) hospital-wide safely reduced length of stay, emergency department admissions, and intensive care unit utilization. This asthma care improvement initiative also lowered overall hospital charges without impacting readmission rates.
Area of Science:
- Pediatric Asthma Management
- Clinical Practice Guidelines
- Hospital Operations
Background:
- Previous studies showed limited hospital-wide impact of asthma clinical practice guidelines (CPGs).
- This study aimed to implement and refine a pediatric asthma CPG for improved outcomes and efficiency across hospital units.
Purpose of the Study:
- To standardize pediatric asthma care from emergency department (ED) arrival through discharge.
- To improve patient outcomes and hospital throughput, including ED, inpatient, and intensive care unit (ICU) care.
- To evaluate the impact of a pediatric asthma CPG on length of stay (LOS), admission rates, ICU utilization, and total charges.
Main Methods:
- An evidence-based pediatric asthma CPG was developed and implemented in an urban, quaternary-care children's hospital.
- The CPG applied to all primary diagnosis asthma encounters for patients aged ≥2 years without complex chronic conditions.
- Statistical process control charts monitored primary outcomes (ED/inpatient LOS, admission rates, ICU admissions, charges) and balancing measures (30-day readmissions, 72-hour relapse).
Main Results:
- Postimplementation, ED LOS for treat-and-release patients decreased from 3.9 to 3.3 hours.
- Hospital LOS reduced from 1.5 to 1.3 days.
- The percentage of ED encounters requiring admission dropped from 23.5% to 18.8%, and ICU admissions decreased from 23.0% to 13.2%.
- Total charges per encounter significantly decreased from $4457 to $3651.
- No significant changes were observed in balancing measures, indicating sustained patient safety.
Conclusions:
- Hospital-wide standardization of a pediatric asthma CPG can be safely implemented across various units.
- The CPG effectively reduces overall hospital resource intensity by decreasing LOS, admissions, ICU services, and associated charges.
- This approach demonstrates a successful strategy for optimizing pediatric asthma care delivery and resource management.
Background:
Standardized pediatric asthma care has been shown to improve measures in specific hospital areas, but to our knowledge, the implementation of an asthma clinical practice guideline (CPG) has not been demonstrated to be associated with improved hospital-wide outcomes. We sought to implement and refine a pediatric asthma CPG to improve outcomes and throughput for the emergency department (ED), inpatient care, and the ICU.
Methods:
An urban, quaternary-care children's hospital developed and implemented an evidence-based, pediatric asthma CPG to standardize care from ED arrival through discharge for all primary diagnosis asthma encounters for patients ≥2 years old without a complex chronic condition. Primary outcomes included ED and inpatient length of stay (LOS), percent ED encounters requiring admission, percent admissions requiring ICU care, and total charges. Balancing measures included the number of asthma discharges between all-cause 30-day readmissions after asthma discharges and asthma relapse within 72 hours. Statistical process control charts were used to monitor and analyze outcomes.
Results:
Analyses included 3650 and 3467 encounters 2 years pre- and postimplementation, respectively. Postimplementation, reductions were seen in ED LOS for treat-and-release patients (3.9 hours vs 3.3 hours), hospital LOS (1.5 days vs 1.3 days), ED encounters requiring admission (23.5% vs 18.8%), admissions requiring ICU (23.0% vs 13.2%), and total charges ($4457 vs $3651). Guideline implementation was not associated with changes in balancing measures.
Conclusions:
The hospital-wide standardization of a pediatric asthma CPG across hospital units can safely reduce overall hospital resource intensity by reducing LOS, admissions, ICU services, and charges.
