Antibiotic Guidelines Lead to Reductions in the Use and Cost of Antibiotics in a University Hospital

The object of this study was to improve the use of antibiotics at Aker University Hospital, a 600-bed university hospital. We developed and implemented guidelines for antibiotic treatment and prophylaxis. We describe the impact of these guidelines on the use and cost of antibiotics and evaluate compliance with the guidelines. From 1994 to 1996 there was an 11% reduction in the use of antibacterial agents and a 42% reduction in the use of antifungal agents. The use of broad-spectrum antibiotics was reduced by 23%. The use of penicillin V and G increased by 5%, dikloxacillin/kloxacillin by 46% and erythromycin by 33%. Compared with 1994 values there was a 27% reduction in antibiotic costs in 1995, amounting to US

It proved possible to reduce the use of broad-spectrum antibacterial and antifungal agents, with significant cost savings. Point-prevalence studies may be a useful tool to detect deviations from guidelines and provide physicians with educational feedback.The object of this study was to improve the use of antibiotics at Aker University Hospital, a 600-bed university hospital.

Impact of an antibiotic policy on antibiotic use in a paediatric department. Individual based follow-up shows that antibiotics were chosen according to diagnoses and bacterial findings

We used a controlled before-and-after design with the aims of reducing both the total consumption of antibiotics and the use of broad-spectrum antibiotics against acute otitis media (AOM), and to study to what extent prescriptions for antibiotics against AOM were dispensed. Information on evidence-based treatment of uncomplicated AOM was provided to doctors and nurses, and written guidelines were implemented. Pamphlets and oral information concerning symptomatic treatment and the limited effect of antibiotic use in AOM were given to parents. Eligible patients were 819 children aged 1-15 y. The proportion of patients receiving a prescription for antibiotics was reduced from 90% at baseline to 74% during the study period. The proportion of prescriptions for penicillin V increased from 72% at baseline to 85% during the study period. There were no significant changes at the control site. The proportion of dispensed prescriptions was 70% both at baseline and during the study period. Educational efforts reduced the total consumption of antibiotics and the use of broad-spectrum antibiotics for AOM in children aged 1-15 y at an emergency call service. Data on antibiotic use in AOM based only on prescribing overestimates the use of antibiotics.

Antibiotic prescribing in nursing homes in an area with low prevalence of antibiotic resistance: compliance with national guidelines.

We present the first 3 cases of confirmed scrub typhus imported to Scandinavia. The patients were infected in Thailand, Laos and Sri Lanka, respectively. Treatment with ciprofloxacin and doxycycline lead to rapid cure in 2 of the patients, while the third patient, who was not treated, had a prolonged convalescence. Specific antibodies against Orientia tsutsugamushi, the causative agent of scrub typhus, were detected in all 3 cases.

Increased antibiotic use in Norwegian hospitals despite a low antibiotic resistance rate

We investigated whether a reduction in antibiotic use at the Aker University Hospital (Aker) led to a reduction in Clostridium difficile-associated diarrhoea (CDAD). We compared the incidence of CDAD in Aker and Tromsoe University Hospitals (Tromsoe) and related it to antibiotic use and facilities for infection control between 1993-2001. For this purpose we also performed point prevalence studies. Total antibiotic use was the same in the two hospitals. In spite of a reduction in the use of broad-spectrum antibiotics in Aker the incidence of CDAD increased during 1993-1999. In Tromsoe the use of broad-spectrum antibiotics and clindamycin was two to three times higher than in Aker, but until 1999 the incidence of CDAD remained constant and only half that of Aker. After 1999 the incidence of CDAD was halved in Aker, and increased three-fold in Tromsoe. Point prevalence studies in 2001 revealed an equal prevalence of antibiotic-associated diarrhoea. The facilities for infection control were better in Tromsoe. The percentage of single rooms were 8% in Aker and 14% in Tromsoe, and the percentage of single rooms with a WC was 6% in Aker and 12% in Tromsoe. The bed occupancy was much higher in Aker than in Tromsoe. Lack of facilities for infection control and higher bed occupancy could have contributed to the higher incidence of CDAD in Aker in spite of decreased use of broad-spectrum antibiotics and clindamycin. To limit CDAD in hospitals the focus must be on both rational antibiotic use and infection control.

The objective of this study was to evaluate antibiotic use in relation to diagnoses and bacteriological findings in a 600-bed Norwegian university hospital. Twelve point-prevalence studies of antibiotic use were conducted between 1996 and 1999. In the point-prevalence studies, 1096 of 6588 adult patients (16.6%) used on average 1.25 antibiotics each. Of the patients who received antibiotics, 35% were treated for hospital-acquired infections. Lower respiratory tract and urinary tract infections accounted for more than half of all antibiotic use. Pencillins represented 54% of antibiotic use, cephalosporins 9%, quinolones 6% and antifungal agents 0.7%. The prescribed daily doses for the penicillins were 2-3 times higher than the defined daily doses. Bacteriological samples were obtained from 929 (85%) patients. Compliance with the guidelines was > 90% and was highest when the results of bacteriological samples were positive. Good compliance led to low prevalence of antibiotic use and the use of narrow-spectrum antibiotics.

Guidelines and clinical Cupertino for rational antibiotic use were implemented in a Norwegian paediatric department in 1994. From 1994 to 1998 the use of antibiotics and expenditures was reduced by 50%. There was an 80% decrease in the use of cloxacillin, a 74% decrease of aminoglycosides and a 59% decrease of cephalosporins. The use of penicillin V and G increased by 14% and ampicillins by 8%. Eight point prevalence studies showed that on average 23% (range 21-38%) of the patients were treated with antibiotics. Penicillins were used in 44% of courses, aminoglycosides in 35% of courses and cephalosporins in 9% of courses. Treatment was mostly adjusted to bacteriological findings. Compliance with guidelines was >90%. Guidelines for rational antibiotic policy and multidisciplinary co-operation lead to reduction in the use and expenses of antibiotics in a paediatric department.
