What does this research mean for the field?

Age, operation type, preoperative lung injury, lack of epidural analgesia, and predicted postoperative forced expiratory volume in 1 second (ppoFEV1) are significant predictors of postoperative morbidity in major thoracic surgery patients and can be combined into a predictive risk score.

Structured PICO

Can a risk scoring system using preoperative and surgical factors predict prolonged ICU stay in patients undergoing major thoracic surgery?

Population

858 patients who underwent major lung and esophageal cancer surgeries between 2005 and 2007 at a single center. Mean age 59 years, 75% male. Excluded patients with predicted post-operative forced expiratory volume in 1 second (ppoFEV1) and predicted post-operative carbon monoxide lung diffusion capacity (ppoDLCO) of less than 30%.

Intervention

Risk scoring system based on age, operation name, preoperative lung injury, lack of epidural analgesia, and predicted postoperative forced expiratory volume in 1 second (ppoFEV1)

Outcome

Prolonged ICU stay (> 3 days) as a representative of postoperative complicationssurrogate

A novel risk scoring system using five readily available perioperative variables can effectively predict the risk of prolonged ICU stay and postoperative complications in patients undergoing major thoracic surgery.

Limitations

Retrospective design
Single-center tertiary care nature
Lack of DLCO or physiological functioning tests for all patients
Intraoperative events not taken into account
Inclusion of esophageal operations may have skewed the scoring system
Requires external validation
