The "Choosing Wisely" initiative in infectious diseases

Choosing Wisely in pediatric healthcare: A narrative review

Background

It has been estimated that 20% of the tests and therapies currently prescribed in North America are likely unnecessary, add no value, and may even cause harm. The Choosing Wisely (CW) campaign was launched in 2012 in the US and Canada to limit the overuse of medical procedures in adult and pediatric healthcare, to avoid overdiagnosis and overtreatment.

Methods

In this narrative review, we describe the birth and spread of the CW campaign all over the world, with emphasis on CW in pediatric healthcare.

Results

To date, CW has spread to more than 25 countries and 80 organizations, with 700 recommendations published. The awareness of medication overuse also made its way into pediatrics. One year after the launch of the CW campaign, the American Academy of Pediatrics and the pediatric section of the Society of Hospital Medicine provided the first recommendations specifically aimed at pediatricians. Thereafter, many European pediatric societies also became active in the CW campaign and published specific top-5 recommendations, although there is not yet a common set of CW recommendations in Europe.

Discussion

We reviewed the main pediatric CW recommendations in medical and surgical fields and discussed how the recommendations have been produced, published, and disseminated. We also analyzed whether and how the CW recommendations impacted pediatric medical practice. Furthermore, we highlighted the common obstacles in applying CW recommendations, such as pressure from patients and families, diagnostic uncertainty, and worries about legal problems. Finally, we highlighted the necessity to foster the CW culture, develop an implementation plan, and measure the results in terms of overuse decline.

Clofazimine as a comparator for preclinical efficacy evaluations of experimental therapeutics against pulmonary M. abscessus infection in mice

Mycobacteroides abscessus (Mab, also known as Mycobacterium abscessus) can cause chronic pulmonary disease in the setting of structural lung conditions. Current treatment recommendations require at least one year of daily therapy with repurposed antibiotics. Yet these therapies are often ineffective and associated with significant adverse events. To address this challenge, research efforts are underway to develop new antibiotics and regimens. During the preclinical phase of treatment development, experimental agents require testing and comparison alongside positive controls that are known agents with clinical history. As there are no FDA approved treatments for this indication, here, we have considered repurposed antibiotics currently included in the recommendation for treating Mab disease as candidates for selection of an ideal standard comparator that can serve as a positive control in preclinical studies. Clofazimine meets the criteria for an ideal positive control as it can be administered via the least invasive route, requires only once-daily dosing, is well tolerated, and is widely available in high purity from independent sources. Using a mouse model of pulmonary Mab disease, we assessed for ideal dosages of clofazimine in C3HeB/FeJ and BALB/c mice in a six-week treatment window. Clofazimine, 25 mg/kg, once daily, produced desired reduction in Mab burden in the lungs of C3HeB/FeJ and BALB/c mice. Based on these findings, we conclude that clofazimine meets the criteria for a positive control comparator in mice for use in preclinical efficacy assessments of agents for treatment of Mab pulmonary disease. Although not included in the current standard-of-care for treating Mab disease, rifabutin, 20 mg/kg, also produced desired reduction in Mab lung burden in C3HeB/FeJ mice but not in BALB/c mice. IMPORTANCE: Mycobacteroides abscessus can cause life-threatening infections in patients with chronic lung conditions. New treatments are needed as cure rate using existing drugs is low. During pre-clinical phase of treatment development, it is important to compare the efficacy of the experimental drug against existing ones with known history. Here, we demonstrate that clofazimine, one of the antibiotics repurposed for treating Mab disease, can serve as a positive control comparator for efficacy assessments of experimental drugs and regimens to treat M. abscessus disease in mice.

Sex and age as determinants of the seroprevalence of anti-measles IgG among European healthcare workers: A systematic review and meta-analysis

INTRODUCTION

The international literature shows good evidence of a significant rate of measles susceptibility among healthcare workers (HCWs). As such, they are an important public health issue.

METHODS

We conducted a systematic review and meta-analysis to estimate the prevalence of susceptible HCWs in EU/EEA countries and in the UK and to explore the characteristics (sex and age differences) and management of those found to be susceptible.

RESULTS

Nineteen studies were included in the meta-analysis. The prevalence of measles-susceptible HCWs was 13.3% (95 %CI: 10.0-17.0%). In a comparison of serosusceptible female vs. male HCWs, the RR was 0.92 (95 %CI = 0.83-1.03), and in a comparison of age classes (born after vs. before 1980) the RR was 2.78 (95 %CI = 2.20-3.50). The most recent studies proposed the mandatory vaccination of HCWs.

DISCUSSION

According to our meta-analysis, the prevalence of serosusceptible European HCWs is 13%; HCWs born in the post-vaccination era seem to be at higher risk. Healthcare professionals susceptible to measles are a serious epidemiological concern. Greater efforts should therefore be made to identify those who have yet to be vaccinated and actively encourage their vaccination.

An innovative telemedical network to improve infectious disease management in critically ill patients and outpatients: a stepped-wedge, cluster randomized controlled trial (TELnet@NRW)

BACKGROUND

Evidence-based infectious disease and intensive care management is more relevant than ever. Medical expertise in the two disciplines is often geographically limited to university institutions. In addition, the interconnection between inpatient and outpatient care is often insufficient (e.g., no shared electronic health record, no digital transfer of patient findings).

OBJECTIVE

To establish and evaluate a telemedical inpatient-outpatient network based on expert teleconsultations to increase treatment quality in intensive care medicine and infectious diseases.

METHODS

We performed a multicentre, stepped-wedge cluster randomised trial (Feb 2017 - Jan 2020) to establish a telemedicine inpatient-outpatient network among university hospitals, hospitals, and outpatient physicians in North Rhine Westphalia, Germany. Patients ≥ 18 years of age in the intensive care unit (ICU) or consulting with a physician in the outpatient setting were eligible. We provided expert knowledge from intensivists and infectious disease specialists through advanced training courses and expert teleconsultations with 24/7/365 availability on demand resp. once per week to enhance treatment quality. The primary outcome was adherence to the ten Choosing Wisely® recommendations for infectious disease management. Guideline adherence was analysed using binary logistic regression models.

RESULTS

Overall, 159,424 patients (10,585 inpatients, 148,839 outpatients) from 17 hospitals and 103 outpatient physicians were included. There was a significant increase in guideline adherence in the management of Staphylococcus aureus infections (OR 4.00 [95% CI 1.83, 9.20], P<.01) and in sepsis management in critically ill patients (OR 6.82 [95% CI 1.27, 56.61], P=.04). There was a statistically non-significant decrease in sepsis related mortality from 28.8% (19/66) in the control group to 23.8% (50/210) in the intervention group. Furthermore, the extension of treatment with prophylactic antibiotics after surgery was significantly less likely (OR 9.37 [95% CI 1.52, 111.47], P=.04). Patients treated by outpatient physicians, who were regularly taking part in expert teleconsultations, were also more likely to be treated according to guideline recommendations regarding antibiotic therapy for uncomplicated upper respiratory tract infections (OR 1.34 [95% CI 1.16, 1.56], P<.01) and asymptomatic bacteriuria (OR 9.31 [95% CI 3.79, 25.94], P<.01). For the other recommendations, we found no significant effects, or we had too few observations to generate models. Key limitations of our study include selection effects due to the applied on-site triage of patients as well as the limited possibilities to control for secular effects.

CONCLUSIONS

Telemedicine facilitates a direct round-the-clock interaction over broad distances between intensivists or infectious disease experts and physicians who care for patients in hospitals without ready access to these experts. Expert teleconsultations increase guideline adherence and treatment quality in infectious disease and intensive care management creating added value for critically ill patients.

[Less is more… in infectious diseases]

BACKGROUND

The increasing development of antimicrobial resistance has been identified as one of the greatest threats to public health and is caused to a relevant extent by falsely indicated antibiotic treatment.

OBJECTIVE

The main aim of this article is to identify areas in infectious disease diagnostics and treatment where overuse occurs and to provide recommendations on how to avoid it.

MATERIAL AND METHODS

The authors identified current and relevant studies on the topic of medical overuse in infectious diseases via a literature search. In particular, contributions from international "less is more" initiatives were included. The focus was on areas in which a reduction of diagnostic and therapeutic measures leads to an optimization of patient outcomes.

RESULTS

In many cases overuse in the context of diagnostics and treatment of infectious diseases not only leads to an unnecessary financial burden on the healthcare system and is not beneficial but can also increase the risk of development of antimicrobial resistance and have adverse consequences for patients.

CONCLUSION

Correct indications as well as focused selection and adequate application of antimicrobial agents is crucial to provide the best possible medical care. Diagnostic and antibiotic stewardship measures, which should be implemented in collaboration with infectious disease specialists, can help to identify and reduce areas of overuse and misuse.

Impact of restricting procalcitonin measurements in a Swiss tertiary-care hospital on antibiotic use, clinical outcomes, and costs: An interrupted time-series analysis

We evaluated the impact of a restriction of procalcitonin measurements on antibiotic use, length of stay, mortality, and cost in a Swiss tertiary-care hospital using interrupted time-series analysis. There was no significant change in level or slope for rates of antibiotic consumption, and costs decreased considerably, by ~54,488 CHF (US$55,714) per month.

Update on the "Choosing Wisely" initiative in infectious diseases in Germany

Purpose

The Choosing Wisely^® initiative is an international campaign addressing over- and underuse of diagnostic and therapeutic measures in infectious diseases among others. Since 2016, the German Society for Infectious Diseases (DGI) has constantly designed new items in this regard. Here we report the most recent recommendations.

Methods

The recommendations of the DGI are part of the “Klug entscheiden” initiative of the German Society of Internal Medicine (DGIM). Topics for the new items were suggested by members of the DGI, checked for scientific evidence and consented within the DGI and the DGIM before publication.

Results

The new recommendations are: (1) individuals with immune-suppression, advanced liver cirrhosis or renal insufficiency should receive a dual pneumococcal vaccination. (2) In case of positive blood cultures with Candida spp. thorough diagnostics and treatment should be initiated. (3) In case of suspected meningitis, adult patients should receive dexamethasone and antibiotics immediately after venipuncture for blood cultures and before potential imaging. (4) In case of suspected meningitis a CT scan before lumbar puncture should not be ordered—except for symptoms indicating high CSF pressure or focal brain pathology or in cases of severe immune-suppression. (5) In patients with suspected severe infections, a minimum of two pairs of blood cultures should be drawn using separate venipunctures prior to antibiotic therapy—regardless of body temperature. There is no need of a minimum time interval in between the blood draws.

Conclusion

Applying these new Choosing Wisely^® recommendations will increase patient safety and the value of health care.

Staphylococcus Aureus Bacteriuria as a Predictor of In-Hospital Mortality in Patients with Staphylococcus Aureus Bacteremia. Results of a Retrospective Cohort Study

Staphylococcus aureus bloodstream infection (SA-BSI) is an infection with increasing morbidity and mortality. Concomitant Staphylococcus aureus bacteriuria (SABU) frequently occurs in patients with SA-BSI. It is considered as either a sign of exacerbation of SA-BSI or a primary source in terms of urosepsis. The clinical implications are still under investigation. In this study, we investigated the role of SABU in patients with SA-BSI and its effect on the patients' mortality. We performed a retrospective cohort study that included all patients in our university hospital (Charité Universitätsmedizin Berlin) between 1 January 2014 and 31 March 2017. We included all patients with positive blood cultures for Staphylococcus aureus who had a urine culture 48 h before or after the first positive blood culture. We identified cases while using the microbiology database and collected additional demographic and clinical parameters, retrospectively, from patient files and charts. We conducted univariate analyses and multivariable Cox regression analysis to evaluate the risk factors for in-hospital mortality. 202 patients met the eligibility criteria. Overall, 55 patients (27.5%) died during their hospital stay. Cox regression showed SABU (OR 2.3), Pitt Bacteremia Score (OR 1.2), as well as moderate to severe liver disease (OR 2.1) to be independent risk factors for in-hospital mortality. Our data indicates that SABU in patients with concurrent SA-BSI is a prognostic marker for in-hospital death. Further studies are needed for evaluating implications for therapeutic optimization.

Practice Patterns of Infectious Diseases Physicians in Transitioning From Intravenous to Oral Therapy in Patients With Bacteremia

Background

Bacteremia in adult patients has traditionally been treated with extended courses of intravenous antibiotics. Data on the use of (or rapid transition to) oral therapy are limited.

Methods

Adult infectious disease physicians participating in the Infectious Diseases Society of America Emerging Infections Network (EIN) were surveyed regarding their use of oral antibiotics in patients with bacteremia. Respondents were asked to assume that patients were hemodynamically stable, recovered bacteria were susceptible to potential antibiotics, adequate source control had been achieved, and patients had adequate gastrointestinal absorption. Variables of specific bacteria, oral agent, and associated infection were included.

Results

A total of 655 (50%) of 1321 EIN participants responded. Under certain conditions, 88% would transition patients with Gram-negative bacteremia to complete a course of therapy with oral antibiotics; 71% would transition patients with Gram-positive bacteremia to oral agents. Only 78 (12%) respondents would not treat any bacteremic patient with oral agents. Most respondents (≥75%) were comfortable treating infections secondary to Enterobacteriaceae, Salmonella, Pseudomonas, Stenotrophomonas, Streptococcus pneumoniae, and β-hemolytic streptococci with oral agents. Fewer than 20% endorsed use of oral antibiotics for Staphylococcus aureus or in cases of endocarditis. Fluoroquinolones and trimethoprim-sulfamethoxazole were the preferred agents in Gram-negative bacteremia; linezolid and β-lactams were the preferred agents in Gram-positive bacteremia.

Conclusions

In select circumstances, the majority of respondents would transition patients to oral antibiotics, in both Gram-negative and Gram-positive bacteremia. Most agreed with the use of oral agents in Gram-negative bacteremia caused by Enterobacteriaceae, but they would not use oral agents for Gram-positive bacteremia caused by S aureus or in endocarditis.

[Infectious diseases - a specialty of internal medicine]

Infectious diseases have recently gained wide public interest. Emerging infections and rising rates of antibiotic resistance are determining this trend. Both challenges will need to be addressed in international and local collaborations between different specialties in medicine and basic science. Infectious diseases as a clinical specialty in this scenario is directly responsible for the care of patients with infectious diseases. Its involvement in the care of patients with complicated infections has proved to be highly effective. Antibiotic stewardship programmes are effective measures in slowing the development of antibiotic resistance and have been widely implemented. But antibiotic stewardship specialists should not be confused with or taken as an alternative to infectious disease experts. Infectious diseases requires appropriate and specific training. It mainly uses the instrumentarium of internal medicine. With the current challenges in modern medicine, infectious diseases in Germany should thus be upgraded from a subspecialty to a clinical specialty, ideally within Internal Medicine.

Better and fulfilling healthcare at lower costs: The need to manage health systems as complex adaptive systems

Rising healthcare costs are major concerns in most high-income countries. Yet, political measures to reduce costs have so far remained futile and have damaged the best interests of patients and citizen. We therefore explored the possibilities to analyze healthcare systems as a socially constructed complex adaptive system (CAS) and found that by their very nature such CAS tend not to respond as expected to top-down interventions. As CAS have emergent behaviors, the focus on their drivers - purpose, economy and behavioral norms - requires particular attention. First, the importance of understanding the purpose of health care as improvement of health and its experience has been emphasized by two recent complementary re-definitions of health and disease. The economic models underpinning today's healthcare - profit maximization - have shifted the focus away from its main purpose. Second, although economic considerations are important, they must serve and not dominate the provision of healthcare delivery. Third, expected health professionals' behavioral norms - to first consider the health and wellbeing of patients - have been codified in the universally accepted Declaration of Geneva 2017. Considering these three aspects it becomes clear that complex adaptive healthcare systems need mindful top-down/bottom-up leadership that supports the nature of innovation for health care driven by local needs. The systemic focus on improving people's health will then result in significant cost reductions.

SOBRINA Spanish study-analysing the frequency, cost and adverse events associated with overuse in primary care: protocol for a retrospective cohort study

INTRODUCTION

Several institutions and quality national agencies have fostered the creation of recommendations on what not to do to reduce overuse in clinical practice. In primary care, their impact has hardly been studied. The frequency of adverse events (AEs) associated with doing what must not be done has not been analysed, either. The aim of this study is to measure the frequency of overuse and AEs associated with doing what must not be done (commission errors) in primary care and their cost.

METHODS AND ANALYSIS

A coordinated, multicentric, national project. A retrospective cohort study using computerised databases of primary care medical records from national agencies and regional health services will be conducted to analyse the frequency of the overuse due to ignore the do-not-do recommendations, and immediately afterwards, depending on their frequency, a representative random sample of medical records will be reviewed with algorithms (triggers) that determine the frequency of AEs associated with these recommendations. Cost will determine by summation of the direct costs due to the consultation, pharmacy, laboratory and imaging activities according to the cases.

ETHICS AND DISSEMINATION

The study protocol has been approved by the Ethics Committee of Primary Care Research of the Valencian Community. We aim to disseminate the findings through international peer-reviewed journals and on the website (http://www.nohacer.es/). Outcomes will be used to incorporate algorithms into the electronic history to assist in making clinical decisions.

TRIAL REGISTRATION NUMBER

NCT03482232; Pre-results.

Implementation of the Procalcitonin Assay in a Rural Hospital

Objective: Most positive studies in procalcitonin (PCT) utilization were done in large, tertiary medical centers. Furthermore, there is a paucity of data describing the implementation process. This article is the first to describe in detail the implementation process and initial outcomes after 6 months of PCT testing in a rural, 65-bed, primary hospital. Methods: Education before and during PCT implementation as well as facility rollout are described. Initial outcomes were assessed using a before and after quasi-experimental study design comparing 2 identical 6-month time periods: May to October 2016 and May to October 2017. Antibiotic consumption is described with days of therapy (DOT) per 1000 patient days (PD). Antimicrobial purchasing costs, admission rates, and length of stay (LOS) are also compared. Results: Antimicrobial consumption was variable with the greatest reduction at 6 months: 856 DOT/1000 PD before versus 576 DOT/1000 PD after (P < .0001). Admission rates and LOS were unaffected. There was no associated savings in antibiotic purchasing costs: $114 189.79 before and $139 829.26 after (difference +$25 639.47). Conclusion: Although implementation of PCT testing is feasible in a rural health care facility, after 6 months, it was associated with a marginal decrease in antibiotic consumption with no decrease in admission rates, LOS, or antibiotic cost savings.

'Lost in Nasal Space': Staphylococcus aureus sepsis associated with Nasal Handkerchief Packing

INTRODUCTION

Staphylococcus aureus frequently causes infections in outpatient and hospital settings and can present as a highly variable entity. Typical manifestations are endocarditis, osteoarticular infections or infection of implanted prostheses, intravascular devices or foreign bodies. A thorough diagnostic evaluation with early focus identification is mandatory to improve patient outcome.

CASE REPORT

We report a case of a 68-year old patient with a history of double allogeneic stem cell transplant for acute myeloid leukemia who developed a S. aureus bacteremia with dissemination, severe sepsis and lethal outcome due to nasal handkerchief packing after nose bleeding.

CONCLUSION

A thorough medical examination with further diagnostic work-up is most important in S. aureus blood stream infection to identify and eradicate the portal(s) of entry, to rule out endocarditis, to search for spinal abscesses, osteomyelitis or spondylodiscitis. Adherence to management guides for clinicians must be of major importance to achieve optimal quality of clinical care, and thus improve patient outcome.

How can we teach medical students to choose wisely? A randomised controlled cross-over study of video- versus text-based case scenarios

BACKGROUND

The Choosing Wisely campaign highlights the importance of clinical reasoning abilities for competent and reflective physicians. The principles of this campaign should be addressed in undergraduate medical education. Recent research suggests that answering questions on important steps in patient management promotes knowledge retention. It is less clear whether increasing the authenticity of educational material by the inclusion of videos further enhances learning outcome.

METHODS

In a prospective randomised controlled cross-over study, we assessed whether repeated video-based testing is more effective than repeated text-based testing in training students to choose appropriate diagnostic tests, arrive at correct diagnoses and identify advisable therapies. Following an entry exam, fourth-year undergraduate medical students attended 10 weekly computer-based seminars during which they studied patient case histories. Each case contained five key feature questions (items) on the diagnosis and treatment of the presented patient. Students were randomly allocated to read text cases (control condition) or watch videos (intervention), and assignment to either text or video was switched between groups every week. Using a within-subjects design, student performance on video-based and text-based items was assessed 13 weeks (exit exam) and 9 months (retention test) after the first day of term. The primary outcome was the within-subject difference in performance on video-based and text-based items in the exit exam.

RESULTS

Of 125 eligible students, 93 provided data for all three exams (response rate 74.4%). Percent scores were significantly higher for video-based than for text-based items in the exit exam (76.2 ± 19.4% vs. 72.4 ± 19.1%, p = 0.026) but not the retention test (69.2 ± 20.2% vs. 66.4 ± 20.3%, p = 0.108). An additional Bayesian analysis of this retention test suggested that video-based training is marginally more effective than text-based training in the long term (Bayes factor 2.36). Regardless of presentation format, student responses revealed a high prevalence of erroneous beliefs that, if applied to the clinical context, could place patients at risk.

CONCLUSION

Repeated video-based key feature testing produces superior short-term learning outcome compared to text-based testing. Given the high prevalence of misconceptions, efforts to improve clinical reasoning training in medical education are warranted. The Choosing Wisely campaign lends itself to being part of this process.

When are Oral Antibiotics a Safe and Effective Choice for Bacterial Bloodstream Infections? An Evidence-Based Narrative Review

Bacterial bloodstream infections (BSIs) are a major cause of morbidity and mortality in the United States. Traditionally, BSIs have been managed with intravenous antimicrobials. However, whether intravenous antimicrobials are necessary for the entirety of the treatment course in BSIs, especially for uncomplicated episodes, is a more controversial matter. Patients that are clinically stable, without signs of shock, or have been stabilized after an initial septic presentation, may be appropriate candidates for treatment of BSIs with oral antimicrobials. There are risks and costs associated with extended courses of intravenous agents, such as the necessity for long-term intravenous catheters, which entail risks for procedural complications, secondary infections, and thrombosis. Oral antimicrobial therapy for bacterial BSIs offers several potential benefits. When selected appropriately, oral antibiotics offer lower cost, fewer side effects, promote antimicrobial stewardship, and are easier for patients. The decision to use oral versus intravenous antibiotics must consider the characteristics of the pathogen, the patient, and the drug. In this narrative review, the authors highlight areas where oral therapy is a safe and effective choice to treat bloodstream infection, and offer guidance and cautions to clinicians managing patients experiencing BSI.

Essentials in the management of S. aureus bloodstream infection

AIMS

Staphylococcus aureus bloodstream infection is one of the most common serious bacterial infections worldwide. It represents a heterogenous clinical entity with a high risk of metastatic complications and a high in-hospital mortality ranging between 20 and 30%. The outcome can be improved by optimised diagnostic and therapeutic management. Thus, our minireview should provide important and often missed pieces of information in the management of S. aureus bloodstream infection.

METHODS

We describe the essentials in the management of S. aureus bloodstream infection.

RESULTS

Five essentials were identified: 1) S. aureus bacteremia should always be considered clinically significant. 2) Length of bacteremia and fever is relevant for diagnostic workup, duration of therapy and prognosis. 3) Prompt identification and eradication of portal of entry and infective/metastatic foci are essential. 4) Infective endocarditis should be excluded. 5) Intravenous treatment for at least two weeks up to 4-6 weeks with antistaphylococcal penicillins for MSSA and vancomycin or daptomycin for MRSA bloodstream infection is indicated.

CONCLUSION

Further efforts should be undertaken to increase the adherence to the essentials in the management of S. aureus bloodstream infection.

Optimizing Test Utilization in the Clinical Microbiology Laboratory: Tools and Opportunities

Optimal laboratory test utilization is important for providing high-quality clinical care and efficiently using limited health care resources. While microbiologists have long been advocates for appropriate laboratory test utilization, the widespread availability of electronic medical records capable of supporting clinician order entry and of clinical decision support tools (CDSTs) has provided expanded opportunities for implementing effective, automated test stewardship protocols. D. Nikolic et al. (J. Clin. Microbiol. 55:3350-3354, 2017, https://doi.org/10.1128/JCM.01052-17) describe the results of implementing a CDST at their institution to curtail stool microbiology testing for patients hospitalized for more than 3 days. Their intervention significantly decreased unnecessary test orders and saved their laboratory over $8,000 in reagent and labor costs during an 11-month postintervention period. That report provides an excellent example of how clinical microbiologists can use electronic tools to optimize laboratory test utilization in their health care system.

[What is the perception of the 10-point plan of the German Federal Ministry of Health against multidrug-resistant pathogens and measures of antibiotic stewardship? : An interdisciplinary analysis among German clinicians and development of a decision tool for urologists]

BACKGROUND

Due to increasing antibiotic resistances, relevant treatment problems are currently emerging in clinical practice. In March 2015, the German Federal Ministry of Health (BMG) published a 10-point plan designed to combat this development. Furthermore, the first German guideline on antibiotic stewardship (ABS) was implemented in 2013 and instructs physicians of different specialties about several treatment considerations. Evidence is scarce on how such concepts (10-point plan/BMG, ABS) are perceived among clinicians.

MATERIALS AND METHODS

Within the MR2 study (Multiinstitutional Reconnaissance of practice with MultiResistant bacteria - a survey focusing on German hospitals), a questionnaire including 4 + 35 items was sent to 18 German hospitals between August and October 2015, surveying internists, gynecologists, general surgeons, and urologists. Using multivariate logistic regression models (MLRM), the impact of medical specialty and further criteria on the endpoints (1) awareness of the 10-point plan/BMG and (2) knowledge of ABS measures were assessed. Fulfillment of endpoints was predefined when average or full knowledge was reported (reference: poor to no knowledge).

RESULTS

Overall response rate was 43% (456/1061) for fully evaluable questionnaires. Only 63.0 and 53.6% of urologists and nonurologists (internists, gynecologists, and general surgeons), respectively, attended training courses regarding multidrug-resistance or antibiotic prescribing in the 12 months prior to the study (P = 0.045). The endpoints average and full knowledge regarding 10-point plan/BMG and ABS measures were fulfilled in only 31.4 and 32.8%, respectively. In MLRM, clinicians with at least one previous training course (reference: no training course) were 2.5- and 3.8-fold more likely to meet respective endpoint criteria (all P < 0.001). Medical specialty (urologists vs. nonurologists) did not significantly impact the endpoints in both MLRM.

CONCLUSIONS

The 10-point plan/BMG and ABS programs should be implemented into clinical practice, but awareness and knowledge of both is insufficient. Thus, it stands to reason that the actual realization of such measures is inadequate and continuous training towards rational prescription of antibiotics is necessary, regardless of medical specialty.
