Preoperative Lung Function Assessment and the Impact of Spirometry Misdiagnosis on Mortality Following Cardiac Surgery
Authors' conclusion
A significant proportion of patients undergoing cardiac surgery have obstructive spirometry, many of whom have no diagnosis of respiratory disease. Mis- or undiagnosed obstructive disease may impact in-hospital mortality.
Study context
- Population
- Consecutive patients undergoing preoperative spirometry before cardiac surgery, single tertiary cardiothoracic teaching hospital, January 2010–September 2020
- Participants
- 16,906 consecutive patients
- Exposure
- Spirometric obstruction and respiratory diagnosis categories
- Diagnosis+/obstruction-n = 568
- Diagnosis-/obstruction+n = 3,672
- Outcome
- In-hospital mortality
