Thoracoscore of Falcoz et al for Predicting the Risk of In-Hospital Death Following Thoracic Surgery

Description

Falcoz et al developed the Thoracoscore for predicting the risk of in-hospital mortality following thoracic surgery. This can help to identify a patient who may benefit from more aggressive management or an alternative therapy. The authors are from Jean-Minjoz Hospital, Calmette Hospital Lille, Larrey Hospital Toulouse, Saint-Jacques Hospital Besancon and Medical School Besacon in France.

Patient selection: thoracic surgery

Outcome: in-hospital death

Parameters:

(1) age in years

(2) gender

(3) ASA class

(4) ECOG performance class

(5) MRC dyspnea score

(6) timing for surgery

(7) procedure

(8) diagnosis

(9) comorbidity score

Parameter	Finding	Points
age in years	< 55 years	0
	55 to 65 years	0.7679
	> 65 years	1.0073
gender	female	0
	male	0.4505
ASA class	1 or 2	0
	3, 4 or 5	0.6057

diagnosis	benign	0
	malignant	1.2423
comorbidity score	0	0

where:

• Age in the text is given as 55-65 and >= 65, which is an issue when the age is 65.

• Comorbidity appears to be the number of comorbidities. The Charlson score is not referenced.

X =

= SUM(points for all 9 parameters) – 7.3737

probability of in-hospital mortality =

= 1 / (1 + EXP((-1) * X))

Performance:

• The c-index is 0.85.

• The Homer-Lemeshow statistic is 3.22.
