Antibiotic stewardship for nurses: Using e-learning modules to bridge the education gap

Objective: The Centers for Disease Control and Prevention has called for an interdisciplinary approach to antibiotic stewardship implementation that includes front-line nurses. The literature to date has identified key factors preventing uptake by nurses: lack of education, poor communication among providers, and unit culture. Three e-learning modules were developed to address the nurses’ education regarding the roles nurses play in antibiotic stewardship, antibiotic resistance, allergy assessment, medication side effects and interactions, pharmacokinetics–pharmacodynamics, culture interpretation, specimen collection, and the antibiogram. A survey was used to assess whether nurses felt more prepared to participate after finishing the modules. Setting: Front-line staff nurses in acute care were assigned e-learning modules as part of their pharmacy’s introduction of an antibiotic stewardship program for nurses. Methods: Nurses viewed the modules and completed a survey designed to rank their usefulness and to assess their attitudes. Results: Overall, 81% of nurses felt that they should be part of the antibiotic stewardship team. After completing the modules, 72% felt more empowered to participate in stewardship discussions and an additional 23% requested more education. Also, 97% felt that the information they learned could be utilized in everyday work regardless of the new program. The most cited barriers to stewardship activities were lack of education (45%) and hospital and/or unit culture (13%). Conclusion: Education and culture need to be addressed to overcome the barriers to nurses’ involvement in antimicrobial stewardship. E-learning can provide a simple and effective first step to educate nurses, with minimal time investment.

Analysis of recurrent urinary tract infection management in women seen in outpatient settings reveals opportunities for antibiotic stewardship interventions

Objectives: We characterized antibiotic prescribing patterns and management practices among recurrent urinary tract infection (rUTI) patients, and we identified factors associated with lack of guideline adherence to antibiotic choice, duration of treatment, and urine cultures obtained. We hypothesized that prior resistance to nitrofurantoin or trimethoprim–sulfamethoxazole (TMP-SMX), shorter intervals between rUTIs, and more frequent rUTIs would be associated with fluoroquinolone or β-lactam prescribing, or longer duration of therapy. Methods: This study was a retrospective database study of adult women with International Classification of Diseases, Tenth Revision (ICD-10) cystitis codes meeting American Urological Association rUTI criteria at outpatient clinics within our academic medical center between 2016 and 2018. We excluded patients with ICD-10 codes indicative of complicated UTI or pyelonephritis. Generalized estimating equations were used for risk-factor analysis. Results: Among 214 patients with 566 visits, 61.5% of prescriptions comprised first-line agents of nitrofurantoin (39.7%) and TMP-SMX (21.5%), followed by second-line choices of fluoroquinolones (27.2%) and β-lactams (11%). Most fluoroquinolone prescriptions (86.7%), TMP-SMX prescriptions (72.2%), and nitrofurantoin prescriptions (60.2%) exceeded the guideline-recommended duration. Approximately half of visits lacked a urine culture. Receiving care through urology via telephone was associated with receiving a β-lactam (adjusted odds ratio [aOR], 6.34; 95% confidence interval [CI], 2.58–15.56) or fluoroquinolone (OR, 2.28; 95% CI, 1.07–4.86). Having >2 rUTIs during the study period and seeking care from a urology practice (RR, 1.28, 95% CI, 1.15–1.44) were associated with longer antibiotic duration. Conclusions: We found low guideline concordance for antibiotic choice, duration of therapy and cultures obtained among rUTI patients. These factors represent new targets for outpatient antibiotic stewardship interventions.

Urinary Tract Infections in Kidney Transplant Recipients—Is There a Need for Antibiotic Stewardship?

(1) Background: Urinary tract infections (UTI) are the most common infections after kidney transplantation. Given the risk of urosepsis and the potential threat to the graft, the threshold for treating UTI and asymptomatic bacteriuria with broad spectrum antibiotics is low. Historically fluoroquinolones were prescription favorites for patients that underwent kidney transplantation (KT). After the recent recommendation to avoid them in these patients, however, alternative treatment strategies need to be investigated (2) Methods: We retrospectively analyzed the charts of 207 consecutive adult kidney transplantations that were performed at the department of General, Visceral and Transplantation Surgery of the University Hospital of Tuebingen between January 2015 and August 2020. All charts were screened for the diagnosis and treatment of asymptomatic bacteriuria (ASB) and urinary tract infections (UTI) and the patients’ clinical characteristics and outcomes were evaluated. (3) Results: Of the 207 patients, 68 patients suffered from urinary tract infections. Patients who developed UTI had worse graft function at discharge (p = 0.024) and at the 12 months follow-up (p < 0.001). The most commonly prescribed antibiotics were Ciprofloxacin and Piperacillin/Tazobactam. To both, bacterial resistance was more common in the study cohort than in the control group. (4) Conclusions: Urinary tract infections appear to be linked to worse graft functions. Thus, prevention and treatment should be accompanied by antibiotic stewardship teams.

Development of antimicrobial resistance due to the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus identified in 2019. This disease, which may cause a serious respiratory infection, has been designated an international public health emergency and is being treated with several types of antivirals, antibiotics, and antifungals. While society works hard to combat the coronavirus disease 2019 (COVID-19) pandemic, it is equally vital to be prepared for the outbreak’s notorious effects on the development of antimicrobial resistance (AMR). Antibiotic misuse and overuse are predicted to have serious ramifications for antibiotic stewardship programs and AMR management worldwide. Importantly, the global influence on the creation of novel antimicrobial resistance is uncertain due to a paucity of data on antimicrobial usage during the COVID-19 pandemic. The current pandemic might be a useful tool for depicting the spread of antimicrobial resistance and underlining the difficulties in managing the issue once it has emerged. This review aims to assess available data on bacterial infections in coronavirus-infected patients and to offer insight into the development of AMR in the face of the current public health issue.

An Overview of Emerging Point-of-Care Tests for Differentiating Bacterial and Viral Infections

Antimicrobial resistance is an important health concern in Canada and around the world. Although resistance arises naturally, the overuse of antibiotics, among many other behavioural, social, and economic drivers, contributes to the emergence of resistance patterns. Within health care settings, diagnostic uncertainty, a situation in which it is uncertain whether a suspected infection is due to a bacterial, viral, or other microorganism, is a regarded as a key driver that contributes to overuse of antibiotics. In these situations, antibiotics may be prescribed although the infection is viral. Emerging health technologies that can help reduce diagnostic uncertainty of acute infections at the point of care may help reduce the unnecessary use of antibiotics. If these point-of-care diagnostic devices demonstrate clinical benefit and cost-effectiveness for health systems, they may complement other interventions as part of antibiotic stewardship programs. This Horizon Scan provides an overview of new and emerging point-of-care tests that help differentiate bacterial and viral infections. Although rapid tests for identifying specific pathogens have existed for decades, these emerging tests aim to assess a wider range of possible pathogens and help inform treatment decisions. Different types of emerging devices, such as rapid molecular tests and immunoassays, are described including how they work and information about their capabilities that may influence their potential use. The report also describes the evidence about the diagnostic accuracy of certain tests and their effect on reducing antibiotic prescribing. Considerations are provided about where tests might be beneficial, such as primary care settings, and the emerging evidence base for their feasibility and acceptability. The emerging evidence suggests that point-of-care tests could be effective tools as part of antibiotic stewardship programs, but further studies assessing specific devices in randomized controlled trials are recommended by researchers and health technology assessment agencies. Monitoring the continued development of devices and the testing landscape, especially in post-pandemic health care, will be important for decision-makers.

Impact and Sustainability of Antibiotic Stewardship on Antibiotic Prescribing in Visceral Surgery

Background: Antibiotic stewardship (AS) ward rounds are a core element in clinical care for surgical patients. Therefore, we aimed to analyze the impact of surgical AS ward rounds on antibiotic prescribing, and the sustainability of the effect after the AS interventions are no longer provided. Methods: On four wards of the department of visceral surgery, we conducted two independent retrospective prescribing analyses (P1, P2) over three months each. During the study periods, the level of AS intervention differed for two of the four wards (ward rounds/no ward rounds). Results: AS ward rounds were associated with a decrease in overall antibiotic consumption (91.1 days of therapy (DOT)/100 patient days (PD) (P1), 70.4 DOT/100PD (P2)), and improved de-escalation rates of antibiotic therapy (W1/2: 25.7% (P1), 40.0% (P2), p = 0.030; W3: 15.4 (P1), 24.2 (P2), p = 0.081). On the ward where AS measures were no longer provided, overall antibiotic usage remained stable (71.3 DOT/100PD (P1), 74.4 DOT/100PD (P2)), showing the sustainability of AS measures. However, the application of last-resort compounds increased from 6.4 DOT/100PD to 12.1 DOT/100PD (oxazolidinones) and from 10.8 DOT/100PD to 13.2 DOT/100PD (carbapenems). Conclusions: Antibiotic consumption can be reduced without negatively affecting patient outcomes. However, achieving lasting positive changes in antibiotic prescribing habits remains a challenge.

Antibiotics in critically ill children—a narrative review on different aspects of a rational approach

Especially critically ill children are exposed to antibiotic overtreatment, mainly caused by the fear of missing out a severe bacterial infection. Potential adverse effects and selection of multi-drug resistant bacteria play minor roles in decision making. This narrative review first describes harm from antibiotics and second focuses on different aspects that could help to reduce antibiotic overtreatment without harming the patient: harm from antibiotic treatment, diagnostic approaches, role of biomarkers, timing of antibiotic therapy, empiric therapy, targeted therapy, and therapeutic drug monitoring. Wherever possible, we linked the described evidence to the current Surviving Sepsis Campaign guidelines. Antibiotic stewardship programs should help guiding antibiotic therapy for critically ill children. Impact Critically ill children can be harmed by inadequate or overuse of antibiotics. Hemodynamically unstable children with a suspicion of infection should be immediately treated with broad-spectrum antibiotics. In contrast, in hemodynamically stable children with sepsis and organ dysfunction, a time frame of 3 h for proper diagnostics may be adequate before starting antibiotics if necessary. Less and more targeted antibiotic treatment can be achieved via antibiotic stewardship programs.

Antibiotic Self-Medication and Antibiotic Resistance: Multilevel Regression Analysis of Repeat Cross-Sectional Survey Data in Europe

Antibiotic resistance is a global public health issue with several anthropogenic drivers, including antibiotic consumption. Recent studies have highlighted that the relationship between antibiotic consumption and antibiotic resistance is contextualised by a variety of socioeconomic, cultural, and governance-related drivers of consumption behaviour and contagion that have been underexamined. A potential complication for research and policy is that measures of antibiotic consumption are often reliant on prescribing or sales data which may not easily take into account the dynamics of community consumption that include self-medication; for example, the preservation and use of leftover medication or the obtaining of antibiotics without a prescription. This study uses repeated cross-sectional survey data to fulfil two core aims: firstly, to examine the individual-level and national-contextual determinants of self-medication among antibiotic consumers in European countries, and secondly, to examine the relationship between self-medication behaviour and antibiotic resistance at the national level. This study is particularly novel in its application of a multilevel modelling specification that includes individual-level factors with both time-variant and persistent national characteristics to examine antibiotic consumption behaviours. The key findings of the study are that survey respondents in countries with persistently higher levels of inequality, burdens of out-of-pocket health expenditure, and corruption have an increased probability of self-medicating with antibiotics. The study also highlights that overall levels of antibiotic consumption and antibiotic self-medication do not correlate and are associated heterogeneously with changes in different pathogen/antibiotic pairs. In summary, the study emphasises that antibiotic stewardship and antibiotic resistance, whilst related by biological mechanisms, are also inherently social issues. Attempts to improve antibiotic stewardship and address the challenge of antibiotic resistance should also attend to structural challenges that underlie challenges to antibiotic stewardship in the community, such as the effects of inequality and reduced access to healthcare services.
