An audit and feedback intervention study increased adherence to antibiotic prescribing guidelines at a Norwegian hospital

Table 3 Comparison of empirical antibiotic prescribing pre- and post-intervention, expressed as percentage-point difference

Antibiotic agent	Pre-intervention (%)	Post-intervention (%)	Percentage-point difference
Benzylpenicillin^a	41.1	53.5	+12.4
Benzylpenicillin + gentamicin^a	8.3	16.1	+7.8
Ampicillin and amoxicillin^a	12.3	14.2	+1.9
Cephalosporines^b	16.2	9.7	−6.5
Tetracyclines^b	14.6	3.2	−11.0
Macrolides	2.8	-	−2.8
Others	4.7	3.2	−1.9

Proportion of patients prescribed the specific antibiotics is calculated based on number of study participants pre- and post-intervention (n = 253 and 155, respectively)
^aCategorized as appropriate, and targeted for increase, ^bFor cephalosporines and doxycyclines percentage difference was −3.8 % and −21.6 % in patients with acute exacerbation of chronic obstructive pulmonary disease and −11.2 % and −2.0 % in patients with community-acquired pneumonia, respectively
