Adherence to the SHEA-IDSA recommendations for the initial treatment of CDI stratified by severity of disease

Treatment adherence according to disease severity (n)	Under-treated	Appropriately treated	Over-treated
Mild-moderate (136)	1 (0.7%)a	81 (59.6%)	54 (39.7%)b
Severe (48)	15 (31.2%)c	27 (56.3%)	6 (12.5%)d
Severe-complicated (46)	30 (65.2%)e	16 (34.8%)	0 (0%)
Total (230)	46 (20%)	124 (54%)	60 (26%)

^aReason for under-treatment was short duration (<10 days) of therapy with metronidazole.

^bThe most common finding of over-treatment in the mild-moderate CDI group was use of oral vancomycin (52 of 54).

^cThe most common finding of under-treatment in the severe CDI group was use of metronidazole instead of vancomycin (14 of 15).

^dThe most common finding of over-treatment in the severe CDI group was use of a combination of metronidazole and vancomycin (four of six).

^eThe most common findings of under-treatment in the severe-complicated CDI group was use of metronidazole alone (5 of 30) or use of vancomycin alone without intravenous metronidazole (8 of 30) or use of vancomycin at 125 mg every 6 h instead of at 500 mg every 6 h in combination with intravenous metronidazole (17 of 30).
