Optimum Timing of Tracheostomy After Cardiac Operation: Descriptive Claims Database Study

Area of Science:

• Cardiothoracic Surgery
• Critical Care Medicine
• Respiratory Therapy

Background:

• Tracheostomy timing post-cardiac operation is debated.
• This study investigates early versus late tracheostomy effectiveness.

Purpose of the Study:

• To compare outcomes of early (1-14 days) versus late (15-30 days) tracheostomy after cardiac surgery.
• To evaluate in-hospital mortality, deep sternal wound infection, and ventilator-free days.

Main Methods:

• Analysis of a Japanese nationwide administrative claims database (April 2010-March 2020).
• Inclusion of patients undergoing cardiac operation and subsequent tracheostomy.
• Propensity score weighting used to adjust for baseline characteristics.

Main Results:

• Early tracheostomy was associated with significantly lower in-hospital mortality (OR 0.65; P=.01).
• No significant difference in deep sternal wound infection rates between groups (OR 0.59; P=.27).
• Early tracheostomy resulted in more ventilator-free days (mean difference 5.1 days; P<.001).

Conclusions:

• Early tracheostomy (1-14 days) may reduce mortality and improve ventilation weaning after cardiac surgery.
• Consider early tracheostomy for cardiac surgery patients anticipated to require prolonged mechanical ventilation.
