Could Thoracoscore predict postoperative mortality in patients undergoing pneumonectomy?

Area of Science:

• Cardiothoracic Surgery
• Surgical Risk Assessment

Background:

• Thoracoscore is a guideline-recommended tool for assessing operative mortality risk in thoracic surgery.
• Accurate risk stratification is crucial for patient management and surgical decision-making.

Purpose of the Study:

• To evaluate the predictive accuracy of Thoracoscore for postoperative mortality in patients undergoing pneumonectomy.
• To compare predicted mortality with actual in-hospital mortality rates.

Main Methods:

• A retrospective analysis of 243 patients who underwent pneumonectomy between January 1998 and March 2008.
• Thoracoscore was calculated using variables including age, sex, ASA class, performance status, dyspnea score, surgery priority, procedure class, diagnosis, and comorbidities.

Main Results:

• The predicted mortality by Thoracoscore was 8 ± 2.6%, while the actual in-hospital mortality was 4.5%.
• Thoracoscore underestimated mortality in the low-risk group and overestimated it in the high-risk group.
• Advanced age (>70), male sex, and pneumonectomy for malignancy were associated with higher in-hospital mortality.

Conclusions:

• Thoracoscore demonstrated limited accuracy in predicting in-hospital mortality for pneumonectomy patients.
• Factors like advanced age, male sex, and malignancy are significant predictors of mortality in this cohort.
• Further validation of Thoracoscore in specific thoracic surgery subgroups is warranted.
