Development of a warning score for early detection of colorectal anastomotic leakage: Hype or hope?

Table 1 Description of assumptions, values, and probabilities for final cost estimation in the decision tree model scenario with adoption of Early ColoRectAL Leakage score on postoperative day

Patient pathway	Assumptions/Observations	€ value	Probability, %
P1	SS and SP of E-CRALL score (Table 5); SS and SP of CT scan[13,21,22]; Full Hospital costs - Ministerial Order nº 254/2018 (Addendum III); Additional Reoperations/CT scan - Ministerial Order nº 254/2018 (Addendum III and IV); LOHS adjustment (reoperation; discharge in advance)	525.10	4.2
P2		1269.70	1.8
P3		379.00	0
P4		499.10	5.3
P5		1243.70	7.9
P6		353.00	80.8

CT: Computed tomography; E-CRALL: Early ColoRectAL Leakage score; LOHS: Length of hospital stay; SP: Specificity; SS: Sensitivity.
