An Analysis of Inhalation Injury Diagnostic Methods and Patient Outcomes.

Area of Science:

• Emergency Medicine
• Critical Care
• Trauma Surgery

Background:

• Burn inhalation injury is a significant cause of morbidity and mortality in burn patients.
• Accurate diagnosis is crucial for appropriate management and improved patient outcomes.

Purpose of the Study:

• To compare patient outcomes based on the diagnostic methods used for burn inhalation injury.
• To identify which diagnostic methods are most predictive of adverse outcomes.

Main Methods:

• Utilized the National Burn Repository Dataset Version 8.0, querying 9775 patients diagnosed with inhalation injury.
• Analyzed subgroups by diagnostic method, comparing mortality, hospital days, intensive care unit (ICU) days, and ventilator days (VDs).
• Employed Z-tests, t-tests, and linear regression with a significance level of P < 0.05.

Main Results:

• Diagnosis by bronchoscopy or carbon monoxide poisoning showed the greatest increase in mortality.
• Bronchoscopy diagnosis was associated with increased hospital days (9), ICU days (8), and VDs (6).
• Combining bronchoscopy with clinical findings amplified adverse outcome predictions, while combining with carbon monoxide poisoning reduced them.

Conclusions:

• Bronchoscopic evidence of inhalation injury is highly predictive of increased mortality, hospital, ICU, and ventilator days.
• A combined diagnostic approach using clinical findings and bronchoscopy is recommended for clinical practice.
• Laryngoscopy diagnosis was not associated with mortality or poor outcomes.
