Performance for Lobectomy Compared to STS and National Outcomes*

* These NIS data are the most recent data available at this time. There are more lobectomy for lung cancer patients in a single year of NIS data than in the GTSD, so a decision was made to use 3 years of STS GTSD data.

**Lobectomy for Lung Cancer Overall Composite Score represents two domain scores in a single number:

Absence of Operative Mortality: Percentage of patients [risk-adjusted] who did not experience operative mortality. Operative mortality is defined as death during the same hospitalization as surgery or after discharge but within 30 days of the procedure.
Absence of Major Morbidity: Percentage of patients [risk-adjusted] who did not experience any major morbidity. These are: 1) pneumonia; 2) acute respiratory distress syndrome; 3) bronchopleural fistula; 4) pulmonary embolus; 5) initial ventilator support > 48 hours; 6) reintubation/respiratory failure; 7) tracheostomy; 8) myocardial infarction; 9) unexpected return to the operating room.

Bayesian Credible Intervals: The Bayesian credible interval shows the range in which the participant’s true score is likely to lie. STS uses 95% credible intervals. Unlike traditional confidence intervals, the Bayesian credible interval has an intuitive probability interpretation. Based on the observed data it can be said that it is 95% likely that the true proportion falls within the upper and lower limits of the 95% credible interval.
