Clinical predictors of pneumonia as a guide to ordering chest roentgenograms
Insights
This study identified clinical criteria, including tachypnea, to improve the efficiency of ordering chest X-rays for pediatric patients. Applying these criteria could reduce the number of unnecessary chest roentgenograms by 30%.
Area of Science:
- Pediatric Emergency Medicine
- Diagnostic Imaging
- Pulmonary Medicine
Background:
- Chest roentgenograms are frequently ordered for pediatric patients presenting with fever or respiratory symptoms.
- There is a need for more efficient criteria to guide the ordering of these diagnostic tests.
- Unnecessary imaging can lead to increased costs and radiation exposure.
Purpose of the Study:
- To develop and evaluate clinical criteria for the efficient ordering of chest roentgenograms in children.
- To identify predictors of pneumonia in pediatric patients presenting with respiratory symptoms.
- To assess the potential reduction in chest roentgenogram utilization with applied criteria.
Main Methods:
- Prospective monitoring of 136 children (3 months to 15 years) in a pediatric emergency room over six months.
- Data collection on symptoms, clinical signs, and diagnostic test results.
- Analysis of 29 individual symptoms and clinical findings to predict pneumonia.
Main Results:
- Pneumonia was diagnosed in 19% of the evaluated children.
- Tachypnea was identified as the single best predictor of pneumonia.
- A cluster of pulmonary findings also proved to be a good indicator for pneumonia.
Conclusions:
- Clinical criteria, particularly tachypnea and a cluster of pulmonary findings, can effectively predict pneumonia in pediatric patients.
- Application of these criteria could potentially reduce the number of chest roentgenograms ordered by 30%.
- This approach offers a more efficient strategy for diagnostic imaging in pediatric emergency settings.
Abstract:
To develop criteria for a more efficient approach to the ordering of chest roentgenograms, patients with fever or respiratory symptoms who were being evaluated with this diagnostic test were prospectively monitored. During a six-month period, residents working in a pediatric emergency room collected data on 136 children, 3 months to 15 years of age. Pneumonia, defined by appropriate abnormal chest roentgenographic findings, occurred in 19 per cent. Of the 29 single symptoms or signs examined, the variable which was the best predictor of pneumonia was tachypnea. In addition, a cluster of pulmonary findings was also a good index, for pneumonia. If these clinical criteria had been applied to the patients under investigation, the number of chest roentgenograms obtained would have been reduced by 30 per cent.
