Brompton Harefield Infection Score (BHIS) of Raja et al

Description

Raja et al reported the Brompton Harefield Infection Score (BHIS) for determining the risk of surgical site infection (SSI) after coronary artery bypass grafting. The authors are from the Harefield Hospital, Brompton Hospital, and the Royal Brompton & Harefield NHS Foundation Trust in England.

Patient selection: status post coronary artery bypass graft (CABG)

Parameters:

(1) diabetes

(2) body mass index (BMI) in kg per square meter

(3) sex

(4) surgical acuity of CABG surgery

(5) left ventricular ejection fraction in percent

Parameter	Finding	Points
diabetes	no	0
	diabetes and HbA1c > 7.5%	3
	other diabetes	1
BMI	< 35	0
	>= 35	2
sex	female	2
	male	0
surgical acuity	emergency	2
	urgent or elective	0
LVEF	>= 45%	0
	< 45%	1

total score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 0

• maximum score: 10

• The higher the score the greater the risk of infection.

Score	Risk Level	Percent SSI
0 or 1	low	2.6%
2 or 3	medium	6%
4 to 10	high	16%

Performance:

• The area under the ROC curve is 0.73.
