Implication

POSSUM models may aid morbidity prediction after lung resection; leaves open prospective validation before routine surgical audit use.

Key Points

To evaluate the POSSUM scoring system in candidates undergoing lung resection and assess its utility as a tool for surgical audit and quality evaluation in thoracic surgery.
Prospectively evaluated 250 consecutive patients undergoing lung resection between 1993 and 1996.
Constructed two logistic regression models: Model I (POSSUM alone) and Model II (POSSUM Physiological Score combined with predicted postoperative FEV1).
Assessed predictive accuracy using receiver operating characteristic (ROC) curve analysis and chi-square goodness-of-fit testing.
Both Model I (AUC = 0.66) and Model II (AUC = 0.67) displayed equivalent discrimination for predicting postoperative complications.
Predicted and observed morbidity showed no significant differences across either model (chi-square test p > 0.05).
Model II demonstrated complete agreement between observed and predicted morbidity in the subgroup of patients with a predicted morbidity exceeding 60%.

Structured PICO

Does the POSSUM scoring system accurately predict postoperative complications in patients undergoing lung resection?

Population

250 consecutive patients submitted to lung resection from 1993 through 1996 at a single institution

Intervention

POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity) scoring system alone (model I) or combined with predicted postoperative FEV1 (model II)

Comparator

Comparison between predicted and observed morbidity, and between model I and model II

Outcome

Postoperative complications (morbidity)

The POSSUM scoring system, either alone or combined with predicted postoperative FEV1, is a valid tool for predicting postoperative morbidity and evaluating surgical quality in lung resection patients.
