An External Validation Study of the Oakland and Glasgow-Blatchford Scores for Predicting Adverse Outcomes of Acute Lower Gastrointestinal Bleeding in an Asian Population

Table 4

Performance of the Oakland and Glasgow-Blatchford scores in comparison with SALGIB scores in the prediction of adverse outcomes.

	Red blood cell transfusion	Hemostatic intervention	Severe ALGIB	In-hospital death	Any adverse outcome
	(26.8%)	(15.2%)	(16.4%)	(1.4%)	(38.9%)
SALGIB	0.91 (0.88-0.94)	0.53 (0.48-0.58)	0.87 (0.83-0.90)	0.82 (0.78-0.86)	0.81 (0.77-0.84)
Oakland	0.93 (0.90-0.95)	0.52 (0.47-0.56)	0.90 (0.87-0.93)	0.77 (0.72-0.81)	0.81 (0.77-0.85)
	Blatchford	0.87 (0.84-0.90)	0.50 (0.45-0.55)	0.83 (0.79-0.87)	0.76 (0.72-0.80)	0.76 (0.72-0.80)

Data are presented as areas under the receiver operating characteristic curve and 95% confidence intervals. Combined outcome of red blood cell transfusion, hemostatic interventions, severe bleeding, and in-hospital death; values are from the DeLong et al. test.
