Early prediction of the need for hospitalization in children with acute asthma
Insights
Spirometry can help predict hospitalization for children with asthma attacks. Combining lung function tests with clinical evaluation improves early identification and reduces misdiagnosis in emergency care.
Area of Science:
- Pediatrics
- Pulmonology
- Emergency Medicine
Background:
- Asthma exacerbations in children present diagnostic challenges in emergency settings.
- Accurate assessment is crucial for timely and appropriate treatment decisions, including hospitalization.
- Pulmonary function testing, like spirometry, may offer objective data to aid clinical judgment.
Purpose of the Study:
- To evaluate the correlation between spirometry and emergency treatment outcomes in children with asthma.
- To determine if spirometry can predict relapse within four days post-treatment.
- To assess the utility of spirometry combined with clinical evaluation for early hospitalization decisions.
Main Methods:
- 133 children (4-17 years) with acute asthma attacks underwent spirometry and clinical scoring.
- Physicians were blinded to spirometry results when making hospitalization decisions based on clinical response.
- A predictive model combining spirometry and clinical evaluation was developed.
Main Results:
- Spirometry and clinical scores alone identified most hospitalizations but misidentified 15-20% of discharged patients.
- The combined predictive criteria significantly reduced false identifications.
- The predictive criteria identified children needing hospitalization an average of 5.5 hours earlier than clinical assessment alone.
Conclusions:
- Spirometry serves as a valuable adjunct to clinical evaluation in emergency asthma care for children.
- Early identification of hospitalization needs can be enhanced by integrating spirometry into the assessment process.
- This approach can optimize resource allocation and patient management during acute asthma exacerbations.
Abstract:
We studied 133 asthmatic children in the emergency room who were aged 4 to 17 years and who were not receiving ongoing training in pulmonary function testing, to determine whether spirometry correlated with the outcome of the emergency treatment of the acute attack and with relapse during the next four days. A clinical score derived from the physical exam was obtained at the time of spirometry. Patients were hospitalized or discharged home based solely on their clinical response to therapy. The pediatrician making that decision was blinded to the results of the spirometry. The initial pretreatment clinical score or spirometry alone identified the majority of patients hospitalized, but each falsely identified many discharged patients who did not relapse, 20 percent and 15 percent, respectively. Predictive criteria for hospitalization, combining spirometry with a careful clinical evaluation prior to the start of emergency treatment, substantially reduced the number of falsely identified patients. With use of the predictive criteria, the majority of children admitted to the hospital would have been identified hours before that decision was made on clinical grounds alone (5.5 +/- 0.7 hrs). This study suggests a role for spirometry as an adjunct to clinical evaluation in the early identification of the need for hospitalization of acutely ill asthmatic children.
