Abstract

We surveyed European medical schools regarding teaching of prudent antibiotic prescribing in the undergraduate curriculum. We performed a cross-sectional survey in 13 European countries (Belgium, Croatia, Denmark, France, Germany, Italy, Netherlands, Norway, Serbia, Slovenia, Spain, Switzerland, United Kingdom) in 2013. Proportional sampling was used, resulting in the selection of two to four medical schools per country. A standardized questionnaire based on literature review and validated by a panel of experts was sent to lecturers in infectious diseases, medical microbiology and clinical pharmacology. In-depth interviews were conducted with four lecturers. Thirty-five of 37 medical schools were included in the study. Prudent antibiotic use principles were taught in all but one medical school, but only four of 13 countries had a national programme. Interactive teaching formats were used less frequently than passive formats. The teaching was mandatory for 53% of the courses and started before clinical training in 71%. We observed wide variations in exposure of students to important principles of prudent antibiotic use among countries and within the same country. Some major principles were poorly covered (e.g. reassessment and duration of antibiotic therapy, communication skills). Whereas 77% of the respondents fully agreed that the teaching of these principles should be prioritized, lack of time, mainly due to rigid curriculum policies, was the main reported barrier to implementation. Given the study design, these are probably optimistic results. Teaching of prudent antibiotic prescribing principles should be improved. National and European programmes for development of specific learning outcomes or competencies are urgently needed.

Abstract

Item does not contain fulltext The Dutch Working Party on Antibiotic Policy (Stichting Werkgroep AntibioticaBeleid, SWAB) was founded in 1996 as an initiative of the Society for Infectious Diseases, the Dutch Society for Medical Microbiology, and the Dutch Association of Hospital Pharmacists. Its primary goal is to contribute to the containment of antimicrobial resistance and the expanding costs incurred for the use of antibiotics. SWAB is the Intersectoral Coordinating Mechanism (ICM) for the Netherlands, and it is at present the National Antimicrobial Resistance (AMR) Focal Point. It coordinates the national surveillance of antibiotic resistance, in collaboration with the National Institute for Public Health and the Environment(RIVM), coordinates the surveillance of the use of antibiotics,and runs a guideline development programme. Information about consumption of antimicrobial agents and antimicrobial resistance among medically important bacteria is presented annually in NethMap. Over the past decade, outpatient consumption of antibiotics has risen only slightly, but in the hospital setting there was an overall significant increase in antibiotic use, due mainly to the steady reduction in the average length of patient hospital stays. In 2006 we introduced our electronic national antibiotic guide 'SWAB-ID' for the antibiotic treatment and prophylaxis of common infectious diseases in hospitals.

Abstract

Background: The extent to which the prognosis for AIDS and death of patients initiating highly active antiretroviral therapy (HAART) continues to be affected by their characteristics at the time of initiation (baseline) is unclear. Methods: We analyzed data on 20,379 treatment-naive HIV-1- infected adults who started HAART in 1 of 12 cohort studies in Europe and North America (61,798 person-years of follow-up, 1844 AIDS events, and 1005 deaths). Results: Although baseline CD4 cell count became less prognostic with time, individuals with a baseline CD4 count 350 cells/μL (hazard ratio for AIDS = 2.3, 95% confidence interval [CI]: 1.0 to 2.3; mortality hazard ratio = 2.5, 95% CI: 1.2 to 5.5, 4 to 6 years after starting HAART). Rates of AIDS were persistently higher in individuals who had experienced an AIDS event before starting HAART. Individuals with presumed transmission by means of injection drug use experienced substantially higher rates of AIDS and death than other individuals throughout follow-up (AIDS hazard ratio = 1.6, 95% CI: 0.8 to 3.0; mortality hazard ratio = 3.5, 95% CI: 2.2 to 5.5, 4 to 6 years after starting HAART). Conclusions: Compared with other patient groups, injection drug users and patients with advanced immunodeficiency at baseline experience substantially increased rates of AIDS and death up to 6 years after starting HAART.

Abstract

Objectives: (1) To determine the pharmacokinetics of sequential intravenous and enteral fluconazole in the serum of surgical intensive care unit (ICU) patients with deep mycoses. (2) To determine the concentrations of fluconazole reached at the site of infection. (3) To determine if enteral administration of fluconazole, which has an important pharmaco-economic advantage, is justified in this specific patient group.Design: Descriptive, sequential study as a part of a therapeutic drug monitoring programme.Setting: Eighteen-bed surgical ICU in a referral centre.Patients: Fourteen critically ill surgical patients with recent gastro-intestinal (GI) surgery and deep mycosis caused by a fluconazole-susceptible fungus and a calculated creatinine clearance of more than 40 ml/min.Interventions: Fluconazole dosage regimen: 400 mg i. v. every 24 h with an extra dose of 400 mg i.v. after 12 h on day 1. If the clinical condition allowed enteral administration on day 4, the content of two capsules of 200 mg was given via the feeding tube with concomitant enteral feeds.Measurements and Main Results: Serum, exudate from the site of infection and urine samples collected at assumed steady state ( after > or = 5 doses). Fluconazole concentrations were determined by high-performance liquid chromatography (HPLC). The mean area under the concentration curve (AUC0-24 h) in serum after enteral administration did not significantly differ from the AUC0-24 h during intravenous treatment. The elimination half-life was longer compared to healthy volunteers. The mean (95% CI) estimated bioavailability was 124 (90-158)%. The mean (95% CI) area under the concentration time curves (AUCs) achieved in the exudate from the site of infection were 67 (55-79)% of the AUCs reached in serum for both regimens.Conclusions: In critically ill patients with recent GI surgery and/or peritonitis the bioavailability of enteral fluconazole was adequate. The concentrations of fluconazole reached in exudate were lower than those in serum for both regimens, but adequate to treat most cases of deep mycoses in this specific patient group.

Abstract

The timing of surgical antimicrobial prophylaxis was determined before and after an intervention programme of education of surgeons, anaesthetists and nurses on the subject of antimicrobial drug prophylaxis, and the subsequent implementation of new protocols of single dose prophylaxis administered within one hour before incision. This prospective study was performed in three surgical departments of a university hospital. For comparison, the timing of prophylaxis was also determined in an operating department of a community hospital. The timing improved considerably in the departments of the university hospital where the intervention was carried out: administration of the first dose within one hour before incision increased from 39% to 69% in department A and from 64% to 80% in department B. Before the intervention, seven out of 16 prophylactic doses were given after inflation of the tourniquet. After the intervention all doses of prophylactic antibiotics were administered before inflation of the tourniquet. Initially, the intervals of multidose prophylaxis varied widely. In the second review, single-dose prophylaxis increased from 21% to 78% in department A and from 31% to 85% in department B. We conclude that the intervention succeeded in improving the quality of surgical prophylaxis. [ABSTRACT FROM AUTHOR]

Abstract

Background: Inpatient quality indicators (IQIs) were previously developed to assess responsible antibiotic use., Aim: Practice testing of these QIs in the hospital setting., Method: This study was performed within a Dutch-Belgian border network of hospitals implementing the Infection Risk Scan (IRIS) point prevalence survey (PPS) as part of the i-4-1-Health project. Twenty out of 51 DRIVE-AB IQIs, including 13 structure and seven process IQIs, were tested. Data on structure IQIs were obtained through a web-based questionnaire sent to the hospital medical microbiologists. PPS data from October to December 2018 were used to calculate performance scores for the process QIs., Findings: Nine hospitals participated. Regarding structure IQIs: the lowest performance scores were observed for recommendations for microbiological investigations in the guidelines and the use of an approval system for restricted antibiotics. In addition, most hospitals reported that some antibiotics were out of stock due to shortages. Regarding process IQIs: 697 systemic antibiotic prescriptions were used to calculate performance scores. The lowest score was observed for documentation of an antibiotic plan in the medical file (58.8%). Performance scores for IQIs on guideline compliance varied between 74.1% and 82.3% for different aspects of the antibiotic regimen (duration, choice, route, timing)., Conclusion: This multicentre practice testing of IQIs identified improvement targets for stewardship efforts for both structure and process aspects of antibiotic care (approval system for restricted antibiotics, documentation of antibiotic plan). These results can guide the design of future PPS studies and a more extensive evaluation of the clinimetric properties of the IQIs., (Copyright © 2022 The Author(s). Published by Elsevier Ltd..

Abstract

Vaccines are applied to large populations, but only recently has research into immunologic responses and mechanisms started to increase exponentially. Some live vaccines, such as the tuberculosis vaccine bacillus Calmette-Guérin, protect against other infections nonspecifically by eliciting complex immune responses which are not specific antibody related. These heterologous effects are explained by the concept of trained immunity. This editorial introduces five narrative reviews offering recent insights on innate and adaptive immune memory towards a variety of pathogens., (Copyright © 2019 European Society of Clinical Microbiology and Infectious Diseases.

Abstract

Objectives: To explore inpatients experiences and views with regard to antibiotics in five European hospitals., Methods: Qualitative study where a patient-centred framework was used to explore inpatients' experiences concerning antibiotic treatment. A purposeful sample of inpatients treated with antibiotics in five hospitals participated in interviews (all centres) and focus groups (Switzerland only)., Results: A total of 31 interviews (five in Belgium, ten in Croatia, nine in France, five in the Netherlands and two in Switzerland) and three focus groups (in Switzerland, 11 participants) were performed. The median age of participants was 61 years (range 33-86 years). The following main themes emerged: (a) patients trust doctors to take the best decisions for them even though communication concerning different antibiotic-related aspects is often insufficient, (b) patients feel that doctors do not prioritize communication due to time constraints and do not seem to adapt information based on patients' preferences, (c) patients differ in their wish to be informed but overall want to be informed on the main aspects in an understandable way, (d) patients often find reassurance in sharing information about their antibiotic treatment with close family, (e) professionals should explore patients' preferences to be involved or not in shared decision making for antibiotic treatment., Conclusion: Inpatients often doubt their ability to understand medical information and trust their physicians to take the best decisions for them. Tailored strategies that inform hospitalized patients, acknowledging their concerns and preferences, may be useful to promote patient involvement and to improve communication regarding antibiotic use., (Copyright © 2018 European Society of Clinical Microbiology and Infectious Diseases.

Abstract

Objectives: We aimed to assess patient-related determinants potentially influencing antibiotic use., Methods: Studies published in MEDLINE until 30 September 2015 were searched. We included: qualitative studies describing patients' self-reported determinants of antibiotic use; and quantitative studies on either self-reported or objectively assessed determinants associated with antibiotic use. Whenever possible, reported determinants were categorized as 'barriers' or 'facilitators' of responsible antibiotic use., Results: A total of 87 studies from 33 countries were included. Seventy-five (86.2%) were quantitative and described self-reported (45/75, 60.0%), objectively assessed (20/75, 26.7%) or self-reported and objectively assessed (10/75, 13.3%) patient-related determinants. Twelve (12/87, 13.8%) were qualitative studies or had a qualitative and quantitative component. Eighty-six of the studies (98.8%) concerned the outpatient setting. We identified seven broad categories of determinants having an impact on different aspects of antibiotic use (in descending order of frequency): demographic and socio-economic characteristics, patient-doctor interactions (e.g. counselling), treatment characteristics (e.g. administration frequency), attitudes (e.g. expecting antibiotics), access to treatment (e.g. patients' direct costs), characteristics of the condition for which the antibiotic was prescribed (e.g. duration of symptoms), knowledge (e.g. regarding indications for treatment). Most determinants were classified as 'barriers' to responsible antibiotic use., Conclusion: A large variety of patient-related determinants impact antibiotic use. The most easily 'modifiable' determinants concern patient-doctor interactions, treatment characteristics and knowledge. Data from the inpatient setting and low- and middle-income countries were underrepresented. Further studies should develop and test interventions that take these determinants into account with the ultimate aim of improving responsible use of antibiotics., (Copyright © 2018 European Society of Clinical Microbiology and Infectious Diseases.
