de Antionio et al reported a nomogram for predicting a serious complication within 90 days of lung resection surgery. This can help to identify a patient who may require more aggressive management. The authors are from multiple institutions from across Spain.
Patient selection: lung resection surgery
Outcome: Clavien Dindo grade 4 complication within 90 days
Parameters:
(1) age
(2) sex
(3) history of previous lung resection for cancer
(4) dyspnea
(5) right pneumonectomy
(6) percent of predicted post-operative DLco based on number of segments left, from 10 to 162
points for age =
= 0.094 * (age)
points for DLCOppo =
= 10 - (0.062 * (percent predicted DLco))

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 29.3
• The higher the score the greater the risk of significant complication.
value of X =
= (0.34 * (score)) - 8.67
probability of Clavien Dindo grade 4 complication within 90 days =
= 1 / (1 + EXP((-1) * X))
Performance:
• The area under the ROC curve is 0.71.
