Unnecessary Antibiotic Prescribing Research Articles

A situational analysis of antibiotic prescription, dispensing practices and resistance pattern in Nepal: Are we losing the battle?

Background: Antibiotics are widely utilized to treat infections and provide preventative and therapeutic benefits in animal and human healthcare. However, because of the emergence and spread of resistance mechanisms, which cause bacteria to become less susceptible to antibiotics and other treatments and less effective, antimicrobial resistance (AMR) has grown to be one of the most significant worldwide public health concerns. Low- and middle-income countries (LMICs) such as Nepal have a high rate of infectious illnesses and antibiotic resistance, which can lead to both human and financial losses. Methods: The information for the scenario analysis was acquired through a review of published and grey literature, as well as interviews with important stakeholders from all sectors. Conclusion: Besides knowing all the challenges of antibiotic resistance, the programs assuring towards AMR is conducted in Nepal in very infrequent way. The antibiotic use should be optimize by giving various personalized treatment approaches and accurate diagnosis which plays vital roles in minimizing unnecessary antibiotic prescriptions. We can organize different awareness programs to reduce antibiotic resistance that may enhance the proper use of antibiotic with proper dose and prescription in accordance health care professionals. Interpreting all the problems, government should give more priority to antibiotic resistance and should be able to minimize the problems. If antibiotic resistance is not taken in a very serious way by all the healthcare workers like doctors, nurses, pharmacists, lab technicians, etc. then the battle we are fighting leads to be defeated and problem will never end.

Antibiotics Prescribing Pattern and Quality of Prescribing in Croatian Dental Practices-5-Year National Study.

Antibiotic resistance is one of the biggest threats to global health today. The aim of this study was to analyze antibiotic prescribing patterns and quality of prescribing in Croatian dental practices over a 5-year period. This is a retrospective observational study based on the analysis of the electronic prescriptions (medicines in ATC groups J01 and P01) from dental practices in Croatia prescribed from 1 January 2015 to 31 December 2019. Prescriptions were retrieved from the Croatian Health Insurance Fund (HZZO). The analyses included the number of prescriptions, type and quantity of prescribed drugs, indication, and the patient's and prescriber's characteristics. The consumption increased from 1.98 DID in 2015, to 2.10 DID in 2019. The most prescribed antibiotic was Amoxicillin with clavulanic acid followed by Amoxicillin, Clindamycin, Metronidazole and Cefalexin. The analyses showed that 29.79% of antibiotics were not prescribed in accordance with the contemporary guidelines for the proper use of antibiotics. Additionally, 22% of antibiotics were prescribed in inconclusive indications. The research showed an increase in antibiotic consumption over five years along with unnecessary prescribing of antibiotics in cases with no indications for its use. The development of national guidelines for antibiotic use is necessary.

Epidemiological Characterization of Respiratory Pathogens Using the Multiplex PCR FilmArray™ Respiratory Panel.

Various pathogens can cause upper respiratory tract infections, presenting challenges in accurate diagnosis due to similar symptomatology. Therefore, rapid and precise diagnostic tests are crucial for effective treatment planning. Traditional culture-based methods for diagnosis are limited by their reliance on skilled personnel and lengthy processing times. In contrast, multiplex polymerase chain reaction (PCR) techniques offer enhanced accuracy and speed in identifying respiratory pathogens. In this study, we aimed to assess the efficacy of the FilmArray™ Respiratory Panel (RP), a multiplex PCR test capable of simultaneously screening 20 pathogens. This retrospective analysis was conducted at Dankook University Hospital, South Korea, between January 2018 and December 2022. Samples from patients with upper respiratory tract infections were analyzed. Results revealed adenovirus as the most prevalent pathogen (18.9%), followed by influenza virus A (16.5%), among others. Notably, a 22.5% co-infection rate was observed. The FilmArray™ RP method successfully identified 20 pathogens within 2 h, facilitating prompt treatment decisions and mitigating unnecessary antibiotic prescriptions. This study underscores the utility of multiplex PCR in respiratory pathogen identification, offering valuable insights for epidemiological surveillance and diagnosis.

Overview of Community Knowledge about The Use of Antibotic in Blungkan Hamlet, Sendangrejo Village, Lamongan Sub-district, Lamongan District

Antibiotics are medications that combat bacterial illnesses. There are several negative health outcomes associated with the current epidemic of antibiotic resistance, including higher rates of illness and death, higher healthcare expenditures, and treatment failures. In 2015, there were an increase of 50 million unnecessary antibiotic prescriptions (Unnescecery prescribing) from 150 million, and this number continues to increase every year. Thus, the number of bacteria that are resistant to antibiotics is increasing. This study aims to determine the extent of public awareness on the utilization of antibiotics in Dusun Blungkan, Sendangrejo village, Lamongan district. The design of this research is descriptive research and data collection using questionnaires with Cronbach's alpha value of 0.83 (>0.60) then the questionnaire is declared reliable that covers 7 domains of knowledge namely understanding antibiotics, antibiotic examples, antibiotics use, dosage, contraindications, side effects, and antibiotic resistance. The results showed that in Dusun Blungkan, Sendangrejo Village, Lamongan District, and Lamongan Province there are 21 (70%) people who are aware of the use of antibiotics. Out of 30 respondents, 21 people (70%) have sufficient knowledge, 7 people (23.3%) have less knowledge, and 2 people (6.7%) have good knowledge. Controlled use of antibiotics can prevent resistance. Therefore, accurate information about the importance of antibiotics and how to use antibiotics properly and correctly is needed, as well as more wisdom in using them to avoid unexpected side effects.

Prevalence of unnecessary antibiotic prescriptions among dental visits, 2019.

The US National Action Plan for Combating Antibiotic-Resistant Bacteria established a goal to decrease unnecessary outpatient antibiotic use by 50%. However, data to inform this goal have been limited to medical settings and have not included dental prescribing. Thus, we sought to identify the proportion of antibiotics prescribed inappropriately by dentists to inform outpatient stewardship efforts. Cross-sectional analysis of 2019 Veterans' Affairs (VA) national electronic health record data. Antibiotics prescribed by dentists were evaluated for appropriateness based on 2 definitions: one derived from current guidelines (consensus-based recommendations) and the other based on relevant clinical literature (nonconsensus). A clustered binomial logistic regression model determined factors associated with discordant prescribing. In total, 92,224 antibiotic prescriptions (63% amoxicillin; mean supply, 8.0 days) were associated with 88,539 dental visits. Prophylaxis for complications in medically compromised patients was associated with the most (30.9%) antibiotic prescriptions, followed by prevention of postsurgical complications (20.1%) and infective endocarditis (18.0%). At the visit level, 15,476 (17.5%) met the consensus-based definition for appropriate antibiotic usage and 56,946 (64.3%) met the nonconsensus definition. More than half of antibiotics prescribed by dentists do not have guidelines supporting their use. Regardless of definition applied, antibiotics prescribed by dentists were commonly unnecessary. Improving prescribing by dentists is critical to reach the national goal to decrease unnecessary antibiotic use.

Perception and views about individualising antibiotic duration for respiratory tract infections when patients feel better: a qualitative study with primary care professionals

BackgroundEvidence shows a high rate of unnecessary antibiotic prescriptions for respiratory tract infections (RTIs) in primary care. There is increasing evidence showing that shorter courses for RTIs are safe and...

The Behavior of Primary Healthcare Doctors Toward Antibiotic Prescriptions for Upper Respiratory Tract Infections.

Unnecessary prescription of antibiotics for patients with upper respiratory tract infections (URTIs) carries the potential risk to the development of bacterial resistance. This study aimed to investigate the behavior of primary healthcare (PHC) physicians toward an antibiotic prescription for URTI, Al-Madinah City, Saudi Arabia in 2021. A cross-sectional study was conducted at PHC centers in Al-Madinah City, Saudi Arabia. The study invited all physicians in the randomly selected 28 PHC centers to participate in the study. A master sheet adopted from a researcher done in the Asir region of Saudi Arabia about the pattern of prescription for URTIwas used and included data about socio-demographic characteristics and data about presenting symptoms and signs of URTIs, the clinical diagnosis, type of medication prescribed, and duration of treatment also, included data about the factors that press physicians to prescribe antibiotics and their response. The questionnairewas filled out and returned back by 140 physicians. The collected data were analyzed and tabulated using appropriate statistical tests. The mean age of the studied physicians was 34.4 ± 7.6 years (25-59 years). General practitioners and specialists were 66.4% and 33.6%, respectively. The prevalence of antibiotic prescriptions was 44.3%. The most prescribed antibiotics were amoxicillin (58.6%)and Augmentin(28.6%). Congested tonsils (87.1%), ear discharge (84.2%), and cervical lymphadenopathy (89.3%) were the most clinical factors that affected physicians' decisions to prescribe antibiotics for URTI. The non-clinical factors affecting physicians' decisions include patient request (52.8%) and press (28.5%), with no statistically significant difference detected between general practitioners and specialists. The study findings indicate the need to develop intervention programs targeting physicians as well as the general population to decrease inappropriate antibiotic prescriptions in primary care centers.

Bacterial infections in patients with COVID-19: the impact of procalcitonin testing on antibiotics prescription in the real world

BackgroundBacterial infections are not prevalent among patients hospitalized with COVID-19, while unnecessary prescription of antibiotics was commonly observed. This study aimed to determine the impact of procalcitonin testing on antibiotics prescription in the real-world setting.MethodsWe performed a territory-wide retrospective cohort study involving all laboratory-confirmed patients hospitalized in public hospitals in Hong Kong in 2020 with COVID-19. We determined the prevalence of bacterial co-infections (documented infections within 72 h of admission) and secondary bacterial infections (infections after 72 h of admission) and antibiotics consumption, and the correlation between procalcitonin testing and antibiotics prescription.ResultsThe cohort included 8666 patients, with mean age 45.3 ± 19.9 years, 48.5% male, and comorbidities in 26.9%. Among 2688 patients with bacterial cultures performed, 147 (5.5%) had bacterial co-infections, and 222 (8.3%) had secondary bacterial infections. Antibiotics were prescribed for 2773 (32.0%) patients during the hospital admission. Procalcitonin tests were performed for 2543 (29.3%) patients. More patients with procalcitonin testing received antibiotics (65.9% vs. 17.9%, p < 0.001). Procalcitonin testing was associated with 5-fold increased risk of antibiotics prescription after adjusting for confounding variables. At hospital level, procalcitonin testing correlated with antibiotics prescription. Patients with procalcitonin level < 0.5 ng/mL had a lower probability of antibiotics initiation and shorter duration of antibiotics therapy.ConclusionsProcalcitonin testing was not associated with lower prescription of antibiotics. Patients with low procalcitonin level had lower antibiotics exposure, supporting the use of procalcitonin to exclude bacterial infections aiding early stopping of antibiotics among patients hospitalized with COVID-19.

Impact of a public commitment charter, a non-prescription pad and an antibiotic information leaflet to improve antibiotic prescription among general practitioners: A randomised controlled study

BackgroundThis study evaluated the effect of a multifaceted antibiotic stewardship intervention on the overall prescription of systemic antibiotics in primary care. Secondary objectives evaluated the effect on the prescription of broad-spectrum antibiotics and the seasonal variation of both total antibiotic and quinolone prescriptions, as a proxy for unnecessary prescribing. MethodsThis pragmatic, randomised, controlled, before-after intervention study was conducted among general practitioners (GPs) who over prescribe antibiotics in Lorraine, France (Intervention group, n = 109; Control group, n = 236; Before period, 01/10/2017–30/09/2018; After period, 01/10/2018–30/09/2019). The intervention included a public commitment charter, a patient information leaflet and a non-prescription pad. Health Insurance data was obtained to calculate overall and broad-spectrum prescription rate (defined daily doses/1000 consultations) and the seasonal variation of prescriptions (%), by period. The intervention effect was measured with general linear mixed models including three independent variables (group, period and group x period interaction). ResultsOverall, compared to the Before period, GPs in both groups prescribed significantly fewer systemic antibiotics (p < 0.001) and broad-spectrum antibiotics (p < 0.001) after the intervention was implemented. However, the group x period interaction did not show any evidence that the intervention had an effect on these outcomes. Nevertheless, the intervention did result in a trend towards less seasonal variation in total systemic antibiotic prescription (p = 0.052). ConclusionsA tendency towards an effect of the intervention to reduce unnecessary antibiotic prescribing during winter months was observed. No effect was observed on the overall volume of systemic antibiotic prescription. This study invites discussion about the challenges faced when evaluating non-pharmacological interventions in primary care.

Barriers to Implementing Registered Nurse-Driven Clinical Decision Support for Antibiotic Stewardship: Retrospective Case Study.

Up to 50% of antibiotic prescriptions for upper respiratory infections (URIs) are inappropriate. Clinical decision support (CDS) systems to mitigate unnecessary antibiotic prescriptions have been implemented into electronic health records, but their use by providers has been limited. As a delegation protocol, we adapted a validated electronic health record-integrated clinical prediction rule (iCPR) CDS-based intervention for registered nurses (RNs), consisting of triage to identify patients with low-acuity URI followed by CDS-guided RN visits. It was implemented in February 2022 as a randomized controlled stepped-wedge trial in 43 primary and urgent care practices within 4 academic health systems in New York, Wisconsin, and Utah. While issues were pragmatically addressed as they arose, a systematic assessment of the barriers to implementation is needed to better understand and address these barriers. We performed a retrospective case study, collecting quantitative and qualitative data regarding clinical workflows and triage-template use from expert interviews, study surveys, routine check-ins with practice personnel, and chart reviews over the first year of implementation of the iCPR intervention. Guided by the updated CFIR (Consolidated Framework for Implementation Research), we characterized the initial barriers to implementing a URI iCPR intervention for RNs in ambulatory care. CFIR constructs were coded as missing, neutral, weak, or strong implementation factors. Barriers were identified within all implementation domains. The strongest barriers were found in the outer setting, with those factors trickling down to impact the inner setting. Local conditions driven by COVID-19 served as one of the strongest barriers, impacting attitudes among practice staff and ultimately contributing to a work infrastructure characterized by staff changes, RN shortages and turnover, and competing responsibilities. Policies and laws regarding scope of practice of RNs varied by state and institutional application of those laws, with some allowing more clinical autonomy for RNs. This necessitated different study procedures at each study site to meet practice requirements, increasing innovation complexity. Similarly, institutional policies led to varying levels of compatibility with existing triage, rooming, and documentation workflows. These workflow conflicts were compounded by limited available resources, as well as an implementation climate of optional participation, few participation incentives, and thus low relative priority compared to other clinical duties. Both between and within health care systems, significant variability existed in workflows for patient intake and triage. Even in a relatively straightforward clinical workflow, workflow and cultural differences appreciably impacted intervention adoption. Takeaways from this study can be applied to other RN delegation protocol implementations of new and innovative CDS tools within existing workflows to support integration and improve uptake. When implementing a system-wide clinical care intervention, considerations must be made for variability in culture and workflows at the state, health system, practice, and individual levels.

Evaluation of Multisite Programmatic Bundle to Reduce Unnecessary Antibiotic Prescribing for Respiratory Infections: A Retrospective Cohort Study.

The aim of this study was to evaluate the frequency of unnecessary antibiotic prescribing for Tier 3 upper respiratory infection (URI) syndromes across the Mayo Clinic Enterprise before and after a multifaceted antimicrobial stewardship intervention, and to determine ongoing factors associated with antibiotic prescribing and repeat respiratory healthcare contact in the postintervention period. This was a quasi-experimental, pre/post, retrospective cohort study from 1 January 2019 through 31 December 2022, with 12-month washout during implementation from 1 July 2020 through 30 June 2021. All outpatient encounters, adult and pediatric, from primary care, urgent care, and emergency medicine specialties with a Tier 3 URI diagnosis were included. The intervention was a multifaceted outpatient antibiotic stewardship bundle. The primary outcome was the rate of antibiotic prescribing in Tier 3 encounters. Secondary outcomes included 14-day repeat healthcare contact for respiratory indications and factors associated with persistent unnecessary prescribing. A total of 165 658 Tier 3 encounters, 96 125 in the preintervention and 69 533 in the postintervention period, were included. Following intervention, the prescribing rate for Tier 3 encounters decreased from 21.7% to 11.2% (P < .001). Repeat 14-day respiratory healthcare contact in the no antibiotic group was lower postintervention (9.9.% vs 9.4%; P = .004). Multivariable models indicated that increasing patient age, Charlson comorbidity index, and primary diagnosis selected were the most important factors associated with persistent unnecessary antibiotic prescribing. Outpatient antibiotic stewardship initiatives can reduce unnecessary antibiotic prescribing for Tier 3 URIs without increasing repeat respiratory healthcare contact. Advancing age and number of comorbidities remain risk factors for persistent unnecessary antibiotic prescribing.

Do clinical and communication skills scores on credentialing exams predict potentially inappropriate antibiotic prescribing?

There is considerable variation among physicians in inappropriate antibiotic prescribing, which is hypothesized to be attributable to diagnostic uncertainty and ineffective communication. The objective of this study was to evaluate whether clinical and communication skills are associated with antibiotic prescribing for upper respiratory infections and sinusitis. A cohort study of 2,526 international medical graduates and 48,394 U.S. Medicare patients diagnosed by study physicians with an upper respiratory infection or sinusitis between July 2014 and November 2015 was conducted. Clinical and communication skills were measured by scores achieved on the Clinical Skills Assessment examination administered by the Educational Commission for Foreign Medical Graduates (ECFMG) as a requirement for entry into U.S residency programs. Medicare Part D data were used to determine whether patients were dispensed an antibiotic following an outpatient evaluation and management visit with the study physician. Physician age, sex, specialty and practice region were retrieved from the ECFMG databased and American Medical Association (AMA) Masterfile. Multivariate GEE logistic regression was used to evaluate the association between clinical and communication skills and antibiotic prescribing, adjusting for other physician and patient characteristics. Physicians prescribed an antibiotic in 71.1% of encounters in which a patient was diagnosed with sinusitis, and 50.5% of encounters for upper respiratory infections. Better interpersonal skills scores were associated with a significant reduction in the odds of antibiotic prescribing (OR per score decile 0.93, 95% CI 0.87-0.99), while greater proficiency in clinical skills and English proficiency were not. Female physicians, those practicing internal medicine compared to family medicine, those with citizenship from the US compared to all other countries, and those practicing in southern of the US were also more likely to prescribe potentially unnecessary antibiotics. Based on this study, physicians with better interpersonal skills are less likely to prescribe antibiotics for acute sinusitis and upper respiratory infections. Future research should examine whether tailored interpersonal skills training to help physicians manage patient expectations for antibiotics could reduce unnecessary antibiotic prescribing.

Association between seasonal influenza vaccination and antimicrobial use in Japan from the 2015-16 to 2020-21 seasons: from the VENUS study.

Seasonal influenza vaccination might be considered an antimicrobial resistance (AMR) countermeasure because it can reduce unnecessary antimicrobial use for acute respiratory infection by mitigating the burden of such diseases. To examine the association between seasonal influenza vaccination and antimicrobial use (AMU) in Japan at the community level and to examine the impact of influenza vaccination on the frequency of unnecessary antimicrobial prescription for upper respiratory infection. For patients who visited any healthcare facility in one of the 23 wards of Tokyo, Japan, due to upper respiratory infection and who were aged 65 years or older, we extracted data from the Vaccine Effectiveness, Networking, and Universal Safety (VENUS) study database, which includes all claims data and vaccination records from the 2015-16 to 2020-21 seasons. We used the average treatment effect (ATE) with 1:1 propensity score matching to examine the association of vaccination status with frequency of antibiotic prescription, frequency of healthcare facility consultation, risk of admission and risk of death in the follow-up period of the same season (from 1 January to 31 March). In total, 244 642 people were enrolled. Matched data included 101 734 people in each of the unvaccinated and vaccinated groups. The ATE of vaccination was -0.004 (95% CI -0.006 to -0.002) for the frequency of antibiotic prescription, -0.005 (-0.007 to -0.004) for the frequency of healthcare facility consultation, -0.001 (-0.002 to -0.001) for the risk of admission and 0.00 (0.00 to 0.00) for the risk of death. Our results suggest that seasonal influenza vaccination is associated with lower frequencies of unnecessary antibiotic prescription and of healthcare facility consultation.

Exploring drivers and challenges influencing antibiotic prescribing in outpatient settings and possible mitigation strategies in the United Arab Emirates: a qualitative study.

Healthcare institutions implement antimicrobial stewardship (AMS) programmes to optimize the use of antibiotics. The focus is often on inpatient rather than outpatient settings. We aimed to explore perceptions of AMS stakeholders on effective interventions for appropriate antibiotic use in outpatient settings, and the role of clinical pharmacists in the AMS multidisciplinary team. A qualitative semi-structured interview study using thematic analysis by two researchers independently. Participants that practice AMS programmes were recruited from healthcare facilities in the United Arab Emirates (UAE). Interviews were conducted face to face or online and transcribed verbatim. Four themes emerged: (i) Perceived factors leading to unnecessary or inappropriate antibiotic prescribing and their impact on patients and the community; (ii) current outpatient AMS activities and perceived barriers and facilitators for their sustainability; (iii) suggested outpatient AMS strategies to be implemented in outpatient settings; and (iv) perceived future AMS implementation barriers and suggested mitigation strategies. Several AMS interventions, together with the presence of a clinical pharmacist, may be effective in improving antibiotic use in UAE outpatient settings. Future research should investigate the most appropriate AMS strategy considering barriers and possible mitigation strategies to ensure sustainability.

Reducing Antibiotic Misuse through the Use of Point-of-Care Tests in Germany: A Survey of 1257 Medical Practices.

Though more than 80% of acute pharyngitis (AP) cases have a viral etiology, it remains one of the most common causes for the unnecessary prescription of antibiotics (ABs). Half of patients receive antibiotics in general practice. Point-of-Care Tests (POCTs) distinguish between bacterial and viral pharyngitis. The objective of this study was to evaluate the use of POCTs using throat swabs to detect β-Streptococcus pyogenes Group A (strep A) infection among patients with sore throat/acute pharyngitis in primary care practices across Germany. A study was conducted in 1257 primary care practices. Two questionnaires were administered concerning frequency, POCT results and whether antibiotics were prescribed. Of the 1257 physicians, 60% used POCTs. Of these, 25% used a POCT before prescribing an antibiotic, 39% in cases of severe sore throat, 40% in cases of long-lasting pharyngitis and 25% in other cases. In total, 83% considered the adoption of POCTs in everyday practice to be important or very important for the diagnosis of strep A, 90% considered it important or very important for achieving a more sensible use of antibiotics and the prevention of bacterial resistance and 80% considered it important or very important for justifying to patients whether or not an antibiotic is needed. POCT results and information on AB prescriptions were available for 583 patients. Of these, 22.5% tested positive for strep A, and 21.8% were prescribed antibiotics. Our study shows that the use of swab tests in patients with sore throat in primary care practices results in high levels of physician satisfaction and can strongly reduce the misuse of antibiotics in clinical practice.

Misoprostol-Induced Fever and Unnecessary Antibiotic Prescribing: A Retrospective Study.

Misoprostol is widely used for medication abortion and postpartum hemorrhage. However, it has been associated with the adverse effect of fever, which can pose challenges in management and potentially contribute to unnecessary antibiotic use. The incidence of misoprostol-induced fever in the context of medical abortion has not been extensively studied. This retrospective cohort study aimed to determine the incidence of fever following misoprostol administration at a tertiary care hospital in Saudi Arabia. The study included female patients who received misoprostol for pregnancy termination or management of missed or incomplete abortion between January 2017 and December 2019. Data on demographics, misoprostol dosage and route, fever characteristics, outcome of abortion, and antibiotic use were collected. Statistical analysis was preformed using appropriate tests. A total of 213 patients were included in the study. The incidence of fever post-misoprostol administration was 8%. Patients who developed fever had a higher gestational age and received higher doses of misoprostol. However, no significant associations were found between other patient variables and fever incidence. Antibiotic therapy was administered to a almost half of the patients who developed fever post-misoprostol but was determined to be unnecessary in all cases. This study contributes to the understanding of misoprostol-induced fever in the context of medical abortion. Further research is needed to explore strategies for reducing unnecessary antibiotic use in this population.

Rules of good practice for the elderly

The treatment of infectious diseases in geriatric medicine is a complex subject. Diagnosis is often difficult, as is the correct indication for antibiotic therapy. To combat antibiotic resistance, we need to limit unnecessary antibiotic prescriptions and prevent the onset of bacterial infections, notably through vaccination.

P23 Prevalence of asymptomatic bacteriuria and associated risk factors in an adult population relevant to UK primary care: a systematic review and meta-analysis

Abstract Background The use of urine dipstick tests in people who are more likely to have asymptomatic bacteriuria (ASB) can lead to the over-diagnosis of urinary tract infection (UTI) and unnecessary antibiotic prescribing. As a result, urine dipsticks are not recommended in those over the age of 65 years, or those with a urinary catheter in UK primary care guidelines. However, due to variation in prevalence estimates for ASB and the age of some of the existing prevalence studies it is unclear whether the use of age 65 as a cut-off for dipstick testing remains appropriate. Objectives This systematic review aims to identify and synthesize more recent evidence around ASB prevalence and other risk factors relevant to a UK community context, in order to improve how UK primary care UTI diagnostic guidance addresses asymptomatic bacteriuria. Methods The protocol for this systematic review is registered with PROSPERO. Inclusion criteria are: study participants aged ≥18 years; prospective studies recruiting from a primary care relevant population; studies that measure ASB prevalence and risk factors; and studies from the Organization for Economic Co-operation and Development member countries. Exclusion criteria include: studies from inpatient hospital settings (including the emergency department); studies exclusively including people who are pregnant, who have urinary catheters, who are post renal transplant or who have structural urological abnormalities; animal studies; laboratory studies; studies published before 1990; and studies not written in English. Searches were conducted in CINAHL, Embase and Medline using MeSH and free text words adapted for each database including terms for bacteriuria AND asymptomatic disease. The Cochrane Collaboration Covidence platform is being used for the management of screening and assessment of studies. Two authors are independently completing screening, data extraction and quality assessments. Results The initial search identified 3891 studies. After screening, 685 are currently undergoing full text review. Overall findings will be reported in a narrative synthesis. We will describe the studies identified, including how ASB has been defined within each of the studies. If sufficient data are available we will complete a meta-analysis. Using standard meta-analysis methods we will generate forest plots showing prevalence and 95% CIs for each study. If possible, we will estimate pooled prevalence of ASB from the reported prevalence of eligible studies, by age group and gender. Conclusions The results of this review may highlight where new evidence around ASB prevalence and risk factors relevant to a UK primary care population is needed.

Antimicrobial resistance landscape and COVID-19 impact in Egypt, Iraq, Jordan, and Lebanon: A survey-based study and expert opinion.

The objective of this study was to assess the antimicrobial resistance (AMR) landscape and the impact of COVID-19 on AMR in Egypt, Iraq, Jordan, and Lebanon, and to gather expert opinions on the barriers to the implementation of antimicrobial stewardship (AMS) initiatives in the region. A cross-sectional questionnaire survey was used to assess the current AMR landscape, existing AMS initiatives, barriers to implementing AMS initiatives, and the impact of COVID-19 on AMR in the four countries. The survey was completed by 204 physicians from Egypt (n = 82), Lebanon (n = 49), Iraq (n = 43), and Jordan (n = 30). Previous antibiotic use and previous bacterial colonization were perceived as the most common risk factors for an increase in AMR. According to the survey, multidrug-resistant (MDR) gram-negative bacteria were most common in lower respiratory tract infections, and Klebsiella pneumoniae and Escherichia coli were the most commonly identified gram-negative bacteria in hospital-acquired infections. Only 14.8% of pediatric physicians and 28.6% of adult physicians reported that target pathogen genotyping and phenotyping were done in hospitals, and the most commonly reported reasons for the lack of testing were technological and resource constraints. These constraints, coupled with the scarcity and high cost of newer antibiotics, have been identified as the most significant barriers to the successful management of MDR gram-negative bacterial infections in the region. It was reported that the spectrum of activity and safety of the antibiotic, the site of infection, the presence of comorbidities, and published guidelines and local antibiograms determined the choice of empirical antibiotic therapy for patients in the region. The four countries experienced a significant rise in AMR due to several factors during the COVID-19 pandemic, including an increase in hospital occupancy, a shift in priorities away from AMR surveillance, and changes in AMR epidemiology. Additionally, the large volumes of unnecessary and unsubstantiated antibiotic prescriptions during the COVID-19 pandemic has led to subsequent antibiotic shortages and significant increases in AMR in the region. Physicians also noted that the majority of COVID-19 patients were already on antibiotics before visiting the healthcare facility. MDR gram-negative bacteria were found in the majority of COVID-19 patients admitted to the intensive care unit. Despite the fact that various AMS initiatives have been implemented, they are not standardized across the region. Some of the main barriers to AMS implementation in the region are a lack of adequately trained AMS staff, lack of AMS knowledge and training among healthcare professionals, financial constraints, and the lack of AMR surveillance systems. These survey results provide valuable insights into the existing AMR and AMS landscape in the region, as well as the barriers that impede efficient AMS and AMR management. Based on these findings, the authors developed a call to action that suggests ways for each country in the region to address these challenges.

Antimicrobial prescribing after rapid influenza PCR implementation in the emergency department

IntroInfluenza shares common symptoms with bacterial pneumonia, which may result in unnecessary antibiotic prescriptions in the emergency department (ED) when the diagnosis is unknown. Rapid influenza polymerase chain reaction (PCR) tests have reduced turnaround times compared to standard multiplex PCR respiratory panels allowing for earlier diagnosis, which may improve antimicrobial stewardship outcomes in the ED. This study aims to compare antibiotic and antiviral use before and after deployment of the rapid influenza PCR in the ED. MethodsThis single-center, retrospective, cohort study included pediatric and adult patients discharged from the ED with a positive influenza test using a standard multiplex PCR respiratory panel (January 2017 – July 2019) or rapid PCR (July 2019 – February 2020). The primary endpoint was number of antibiotic prescriptions pre- and post-implementation of the rapid influenza PCR in the ED. Secondary endpoints included number of antiviral prescriptions, duration of antimicrobial therapy, test turnaround time, ED length of stay, 30-day readmission, and adverse events. A multivariable logistic regression evaluated patient factors associated with antimicrobial prescribing. ResultsA total of 620 positive influenza results were identified with 280 patients (standard multiplex PCR = 33; rapid PCR = 247) meeting inclusion criteria. Patients were less likely to be prescribed antibiotics (39.4% vs 8.9%, OR 0.15, 95% CI 0.067–0.34) and more likely to be prescribed antivirals (24.2% vs 61.1%, OR 4.92, 95% CI 2.13–11.34) with the rapid influenza PCR. Rapid influenza PCR significantly reduced ED length of stay (4.9 vs 3.4 h, p < 0.01) and test turnaround time (27 h vs 3.5 h, p < 0.01). Patients at high risk for complications associated with influenza were more likely to be prescribed antiviral therapy (22.7% vs 67.8%, OR 7.16, 95% CI 2.52–20.40). Based on the regression analysis conducted, asthma, (OR 3.5, 95% CI 1.48–8.26), immunosuppression (OR 9.6, 95% CI 1.18–78.2), and age <5 years old (OR 3.1, 95% CI 1.80–5.45) were predictors of antiviral prescribing. ConclusionImplementation of a rapid influenza PCR in the ED reduced antibiotic use and optimized antiviral therapy for patients with influenza including those at higher risk of complications.
