The ESAC PPS provided useful information on the quality of prescribing, which identified a number of targets for quality improvement. These could apply to specific departments or whole hospitals. Intensive care, which has different characteristics, should not be compared with general wards with respect to combination therapy, hospital-acquired infections or parenteral proportion. The study confirmed that the ESAC PPS methodology can be used on a large number of hospitals at regional, national, continental or global level.
All episodes of bloodstream infection in patients admitted to a Norwegian university hospital in 1974-1979 and in 1988-1989 were analyzed; altogether, there were 1,447 episodes involving 1,286 patients, and 54.3% of all episodes were hospital-acquired. The incidence of bloodstream infection increased between the two periods studied from 4.26/1,000 admissions to 8.71/1,000. Crude mortality rates were 27.6% and 18.8% and attributable mortality rates were 12.3% and 6.9% in the first and second periods, respectively. Patients > 60 years of age accounted for more than half of the bloodstream infections; mortality in this group was significantly higher than that among younger patients (31.4% vs. 13.9%). The frequency of isolation of Enterobacteriaceae decreased from 48% in the first period to 34% in the second, while the rate of isolation of coagulase-negative staphylococci increased from 6.5% to 16.9%. The shift in etiology may be explained in part by the occurrence of significantly more bloodstream infections related to intravascular devices, endocarditis, and skin and wound infections and of significantly fewer episodes related to abdominal or genitourinary disease in the second than in the first period. Almost all isolates of Enterobacteriaceae were susceptible to newer cephalosporins and aminoglycosides. In 1974-1979, 96 (69.1%) of 139 patients with septic shock died; in 1988-1989, the figure was 35 (52.2%) of 67 patients (P = .019). Clinical factors predictive of an adverse outcome were septic shock (odds ratio for first/second period, 12.7/4.6), intensive care treatment (not significant/10.6), malignant disease (4.6/2.6), any underlying disease (4.2/not significant), diabetes mellitus (3.6/not significant), age of> 60 years (not significant/3.0), and pulmonary source of infection (not significant/2.8).
There was a substantial increase in total antibiotic use, and an even more pronounced increase in the use of broad-spectrum antibiotics, which seems unjustified considering the current low antibiotic resistance in Norway.
Background: Procalcitonin is an inflammatory biomarker that is sensitive for bacterial infections and a promising clinical decision aid in antimicrobial stewardship programs. However, there are few studies of physicians' experiences concerning the use of PCT. The objective of this study was to investigate whether hospital physicians' experience with procalcitonin after 18 months of use can inform the PCT implementation in antimicrobial stewardship programs. Materials/methods: We deployed a qualitative approach using semi-structured interviews with 14 hospital physicians who had experience with procalcitonin in clinical practice. Interviews were audio-taped, transcribed verbatim and analysed using thematic analysis. Results: Physicians reported a knowledge gap, which made them uncertain about the appropriate procalcitonin use, interpretation, and trustworthiness. Simultaneously, the physicians experienced procalcitonin as a useful clinical decision aid but emphasised that their clinical evaluation of the patient was the most important factor when deciding on antibiotic treatment. Conclusions: Procalcitonin was regarded a helpful clinical tool, but the physicians called for more knowledge about its appropriate uses. Active implementation of unambiguous procalcitonin algorithms and physician education may enhance the utility of the test as an antimicrobial stewardship adjunct.
The low-set WHO DDDs for penicillins caused skewed surveillance results that concealed the real magnitude of broad-spectrum antibiotic use and distorted interhospital comparisons. For surveillance of antibiotic use in hospitals, WHO DDDs should be supplemented with haDDDs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
