Table 3.

Extended-spectrum beta-lactamase (ESBL) prediction score.

Patient-Specific Characteristic	Points
Outpatient GI/GU procedure in past 30 days	1
One beta-lactam or fluoroquinolone courses within past 90 days	1
Two or more beta-lactam or fluoroquinolone courses within past 90 days	3
Documented colonization or infections with ESBLs within past 12 months	4
ESBL Risk Score Interpretation Score < 3 implies < 10% predicted probability of ceftriaxone resistance for Enterobacterales Score ≥ 3 implies > 20% predicted probability of ceftriaxone resistance for Enterobacterales
May utilize local validated risk scores if applicable with corresponding risk cutoffs
