PurposeAntimicrobial resistance (AMR) is a serious threat to the humanity now a days. To prevent it, the first step is to know about our antibiotic practices. Audit is the first step in continuous quality improvement which intend to go ahead. Antibiotic stewardship involves appropriate antibiotic (empirical or definitive) at correct time in correct doses and frequency for appropriate duration.MethodWe conducted a retrospective study in intensive care unit at our tertiary care center of Bihar, India. Our aim was to know about empirical antibiotic we are prescribing in suspected sepsis patients and their rationality too. National treatment guidelines for infectious disease released by National Centre for Disease Control (NCDC) was taken as standard of care. We recorded demographic profile, SOFA (Sequential Organ Failure Assessment), APACHE II (Acute Physiology and Chronic Health Evaluation), antibiotic prescribed, final etiology of infection, and outcome of the patient and total ICU stay.ResultWe found that combination of two antibiotics were given in majority of patients (53%) and the third generation cephalosporin was the most commonly prescribed antibiotic. In our audit, rational combinations according to the antibiotic policies were given in 73.7% of patients. Appropriate doses of antibiotics were given in 89.5% of patients.ConclusionAudit is a mandatory exercise to provide quality care in the health care system.  相似文献

BackgroundAdding procalcitonin (PCT) to antibiotic stewardship algorithms may improve antibiotic use. However, PCT protocols need to be adapted to clinical settings and patient populations.ObjectivesTo review PCT use in different medical settings and patient populations.SourcesMost recent trials and meta-analyses investigating PCT for antibiotic stewardship were reviewed.ContentSeveral trials found PCT-guided antibiotic stewardship to reduce antibiotic exposure and associated side-effects among patients with respiratory infection and sepsis. Decisions regarding antibiotic use in an individual patient are complex and should be based on the pre-test probability for bacterial infection, the severity of presentation and the results of PCT. In the context of a low pre-test probability for bacterial infections and a low-risk patient, a low PCT level helps to rule out bacterial infection and empiric antibiotic therapy can be avoided. In the context of a high pre-test probability for bacterial infections and/or a high-risk patient with sepsis, monitoring of PCT over time helps to track the resolution of infection and decisions regarding early stop of antibiotic treatment. Although these concepts have been successful in several respiratory infection and sepsis trials, some studies failed to show an added benefit of PCT due to factors such as low protocol adherence and relying on single rather than repeat PCT measurements.ImplicationAs an adjunct to other clinical and laboratory parameters, PCT provides information about risk for bacterial infection and resolution of infection, and improves antibiotic stewardship decisions, thereby offering more individualized treatment courses with overall reduced antibiotic exposure.  相似文献

BackgroundAntimicrobial stewardship (AMS) describes a coherent set of actions that ensure optimal use of antimicrobials to improve patient outcomes, while limiting the risk of adverse events (including antimicrobial resistance (AMR)). Introduction of AMS programmes in hospitals is part of most national action plans to mitigate AMR, yet the optimal components and actions of such a programme remain undetermined.ObjectivesTo describe how health-care professionals can start an AMS programme in their hospital, the components of such a programme and the evidence base for its implementation.SourcesNational and society-led guidelines on AMS, peer-reviewed publications and experience of AMS experts conducting AMS programmes.ContentWe provide a step-by-step pragmatic guide to setting up and implementing a hospital AMS programme in high-income or low-and-middle-income countries.ImplicationsAntimicrobial stewardship programmes in hospitals are a vital component of national action plans for AMR, and have been shown to significantly reduce AMR, particularly when coupled with infection prevention and control interventions. This step-by-step guide of ‘how to’ set up an AMS programme will help health-care professionals involved in AMS to optimally design and implement their actions.  相似文献

ObjectivesAcceptance of prospective audit and feedback antimicrobial stewardship programme (ASP) recommendations has been shown to vary, but the drivers of recommendation acceptance are not well understood. We sought to identify the factors associated with recommendation acceptance at a large community teaching hospital.MethodsData from an ASP recommendation registry were collected from 2010 to 2018. Variables included data about the infection, the prescriber, and the recommendation, categorized by whether they increase, decrease, or are neutral to antibiotic exposure. The primary outcome was acceptance of ASP recommendations. Adjusted odds ratios and 95% confidence intervals were estimated using logistic regression models with random intercepts in order to account for clustering by prescriber.ResultsOver the 8-year period, a total of 11 014 evaluable recommendations were made to 146 prescribers, and 9058 (82.2%) were accepted. The most common recommendations were: reduce duration (n = 2796; 25%), stop antibiotics (n = 2184; 20%), de-escalate (n = 1876; 17%) and increase duration (n = 1176; 11%). Acceptance by service ranged from 70% (n = 843/1196) (surgery) to 86% (n = 6378/7444) (general medicine). In the multivariable analysis, compared to recommendations that have a neutral impact on antibiotic exposure, recommendations to decrease antibiotic exposure had lower odds of acceptance (aOR 0.73; 95%CI 0.64–0.84) while recommendations to increase exposure were associated with greater acceptance (aOR 2.00; 95%CI 1.62–2.45). Other factors associated with increased acceptance included the presence of the ASP physician during rounds and making the recommendation verbally.ConclusionsRecommendations to decrease antibiotic exposure had lower odds of acceptance than those to increase antibiotic exposure. This study presents important considerations for ASPs with prospective audit and feedback programmes aiming to evaluate and increase the impact of their recommendations.  相似文献

BackgroundCOVID-19 and antimicrobial resistance (AMR) are two intersecting global public health crises.ObjectiveWe aimed to describe the impact of the COVID-19 pandemic on AMR across health care settings.Data sourceA search was conducted in December 2021 in WHO COVID-19 Research Database with forward citation searching up to June 2022.Study eligibilityStudies evaluating the impact of COVID-19 on AMR in any population were included and influencing factors were extracted. Reporting of enhanced infection prevention and control and/or antimicrobial stewardship programs was noted.MethodsPooling was done separately for Gram-negative and Gram-positive organisms. Random-effects meta-analysis was performed.ResultsOf 6036 studies screened, 28 were included and 23 provided sufficient data for meta-analysis. The majority of studies focused on hospital settings (n = 25, 89%). The COVID-19 pandemic was not associated with a change in the incidence density (incidence rate ratio 0.99, 95% CI: 0.67–1.47) or proportion (risk ratio 0.91, 95% CI: 0.55–1.49) of methicillin-resistant Staphylococcus aureus or vancomycin-resistant enterococci cases. A non-statistically significant increase was noted for resistant Gram-negative organisms (i.e. extended-spectrum beta-lactamase, carbapenem-resistant Enterobacterales, carbapenem or multi-drug resistant or carbapenem-resistant Pseudomonas aeruginosa or Acinetobacter baumannii, incidence rate ratio 1.64, 95% CI: 0.92–2.92; risk ratio 1.08, 95% CI: 0.91–1.29). The absence of reported enhanced infection prevention and control and/or antimicrobial stewardship programs initiatives was associated with an increase in gram-negative AMR (risk ratio 1.11, 95% CI: 1.03–1.20). However, a test for subgroup differences showed no statistically significant difference between the presence and absence of these initiatives (p 0.40).ConclusionThe COVID-19 pandemic may have hastened the emergence and transmission of AMR, particularly for Gram-negative organisms in hospital settings. But there is considerable heterogeneity in both the AMR metrics used and the rate of resistance reported across studies. These findings reinforce the need for strengthened infection prevention, antimicrobial stewardship, and AMR surveillance in the context of the COVID-19 pandemic.  相似文献

BackgroundThe COVID-19 pandemic has raised concerns over secondary infections because it has limited treatment options and empiric antimicrobial treatment poses serious risks of aggravating antimicrobial resistance (AMR). Studies have shown that COVID-19 patients are predisposed to develop secondary infections. This study was conducted to ascertain the prevalence and profiles of co- & secondary infections in patients at the COVID-19 facility in North India.MethodsWe studied the profile of pathogens isolated from 290 clinical samples. Bacterial and fungal pathogens were identified, and antimicrobial susceptibility was determined by the Vitek2® system. Additionally, respiratory samples were tested for any viral/atypical bacterial co-infections and the presence of AMR genes by FilmArray test. The clinical and outcome data of these patients were also recorded for demographic and outcome measures analyses.ResultsA total of 151 (13%) patients had secondary infections, and most got infected within the first 14 days of hospital admission. Patients aged >50 years developed severe symptoms (p = 0.0004) and/or had a fatal outcome (p = 0.0005). In-hospital mortality was 33%.K.pneumoniae (33.3%) was the predominant pathogen, followed by A. baumannii (27.1%). The overall resistance was up to 84%.Majority of the organisms were multidrug-resistant (MDR) harbouring MDR genes.ConclusionA high rate of secondary infections with resistant pathogens in COVID-19 patients highlights the importance of antimicrobial stewardship programs focussing on supporting the optimal selection of empiric treatment and rapid-de-escalation, based on culture reports.  相似文献

BackgroundAntimicrobial stewardship aims to optimize antibiotic use and minimize selection of antimicrobial resistance. The methodological quality of published studies in this field is unknown.AimsOur objective was to perform a comprehensive systematic review of antimicrobial stewardship research design and identify features which limit validity and translation of research findings into clinical practice.SourcesThe following online database was searched: PubMed.Study eligibility criteriaStudies published between January 1950 and January 2017, evaluating any antimicrobial stewardship intervention in the community or hospital setting, without restriction on study design or outcome.ContentWe extracted data on pre-specified design quality features and factors that may influence design choices including (1) clinical setting, (2) age group studied, (3) when the study was conducted, (4) geographical region, and (5) financial support received. The initial search yielded 17 382 articles; 1008 were selected for full-text screening, of which 825 were included. Most studies (675/825, 82%) were non-experimental; 104 (15%) used interrupted time series analysis, 41 (6%) used external controls, and 19 (3%) used both. Studies in the community setting fulfilled a median of five out of 10 quality features (IQR 3–7) and 3 (IQR 2–4) in the hospital setting. Community setting studies (25%, 205/825) were significantly more likely to use randomization (OR 5.9; 95% CI 3.8–9.2), external controls (OR 5.6; 95% CI 3.6–8.5), and multiple centres (OR 10.5; 95% CI 7.1–15.7). From all studies, only 48% (398/825) reported clinical and 23% (190/825) reported microbiological outcomes. Quality did not improve over time.ImplicationsOverall quality of antimicrobial stewardship studies is low and has not improved over time. Most studies do not report clinical and microbiological outcome data. Studies conducted in the community setting were associated with better quality. These limitations should inform the design of future stewardship evaluations so that a robust evidence base can be built to guide clinical practice.  相似文献

BackgroundAntibody-mediated rejection (AMR) of cardiac allografts is associated with reduced long-term graft survival, but not every patient with AMR develops premature graft failure. The tissue level mechanisms leading to graft failure in some patients with antibody-mediated rejection are poorly characterized.MethodsWe assessed changes in myocardial microvessel density (number of capillaries per unit area) in endomyocardial biopsies over time using whole-slide microscopic imaging of CD34-stained slides and computer-assisted image analysis. Changes were compared among eight heart transplant recipients with multiple episodes of pathologic AMR who died from cardiovascular causes, eight age- and gender-matched patients with pathologic AMR who were still alive at a similar follow-up interval, and six matched controls without AMR or cellular rejection.ResultsMicrovessel density decreased in the last biopsies (mean 6.52 years post-transplant) from patients with pathologic AMR and cardiovascular mortality compared to their biopsies at 6 and 12 months post-transplant [respectively, ?22% (P=.02) and ?25% (P=.02)]. A similar decrease was not seen for the other groups.ConclusionsSignificantly reduced myocardial microvessel density does occur in a subset of patients with pathologic AMR who have a worse outcome. These data provide insights into the interplay between AMR, microvascular injury, and clinical outcomes.  相似文献

PurposeThis paper explores inclusion of topics on antimicrobial resistance (AMR) and antimicrobial stewardship (AMS) in pre-service human and animal healthcare professional curricula as mandated in the first strategic objective of National Action Plan on Antimicrobial Resistance.MethodsOnline versions of pre-service medical [Bachelor of Medicine, Bachelor of Surgery (MBBS)], dental [Bachelor of dental sciences (BDS)], pharmacy [Bachelor of Pharmacy (B Pharm)], veterinary [Bachelor of veterinary science and animal husbandry (B.V.Sc. & A.H.)] and post graduate medical [Doctor of medicine (MD), Master of surgery (MS) and post graduate (PG) medical diploma courses] curricula and hardcopy of nursing (Bachelor of science (BSc) Nursing-Basic) curricula were assessed. Validated search terms were used for identifying individual learning topics, domains of learning and number of hours of learning related to AMS and AMR. Recent edition of commonly referred medical textbooks were manually checked for inclusion of chapters or separate sections on AMR and AMS.ResultsLow coverage and poor depth with no mention of required duration of learning for AMR and AMS was observed across the majority of curricula. MS, BDS, B Pharm and BSc nursing curricula did not include AMR and AMS. Out of twenty-three textbooks assessed, only six textbooks included AMS. Gynecology, Obstetrics, Orthopedic and Surgery textbooks did not include separate section on AMR or AMS.ConclusionsOur study documented inadequate inclusion of AMR and AMS in pre-service medical, dental, nursing, pharmacy and veterinary curricula and post graduate medical curriculum. Standardized education regarding AMR and AMS in multi-professional curricula by educational councils across sectors and updating of medical textbooks of all the subjects by authors/publishers for adequate emphasis on these topics is urgently needed for success of ‘One health’ in combating AMR.  相似文献

BackgroundEmergency departments (EDs) are the entrance gates for patients presenting with infectious diseases into the hospital, yet most antimicrobial stewardship programmes are primarily focused on inpatient management. With equally high rates of inappropriate antibiotic use, the ED is a frequently overlooked yet important unit for targeted antimicrobial stewardship (AMS) interventions.ObjectivesWe aimed to (a) describe the specific aspects of antimicrobial stewardship in the ED and (b) summarize the findings from improvement studies that have investigated the effectiveness of antimicrobial stewardship interventions in the ED setting.Sources: (a) a PubMed search for ‘antimicrobial stewardship’ and ‘emergency department’, and (b) published reviews on effectiveness combined with publications from the first source.Content: (a) An in depth analysis of selected publications provided four key antimicrobial use processes typically performed by front-line healthcare professionals in the ED: making a (tentative) clinical diagnosis, starting empirical therapy based on that diagnosis, performing microbiological tests before starting that therapy and following up patients who are discharged from the ED. (b) Further, we discuss the literature on improvement strategies in the ED focusing on guidelines and clinical pathways and multifaceted improvement strategies. We also summarize the evidence of microbiologic culture review.Implications: Based on our review of the literature, we describe four essential elements of antimicrobial use in the ED. Studying the various interventions targeting these care processes, we have found them to be of a variable degree of success. Nonetheless, while there is a paucity of AS studies specifically targeting the ED, there is a growing body of evidence that AS programmes in the ED are effective with modifications to the ED setting. We present key questions for future research.  相似文献

BackgroundPretransplant anti-HLA donor-specific antibodies (DSA) are recognized as a risk factor for acute antibody-mediated rejection (AMR) in kidney transplantation. The predictive value of C4d-fixing capability by DSA or of IgG DSA subclasses for acute AMR in the pretransplant setting has been recently studied. In addition DSA strength assessed by mean fluorescence intensity (MFI) may improve risk stratification. We aimed to analyze the relevance of preformed DSA and of DSA MFI values.Methods280 consecutive patients with negative complement-dependent cytotoxicity crossmatches received a kidney transplant between 01/2008 and 03/2014. Sera were screened for the presence of DSA with a solid-phase assays on a Luminex flow analyzer, and the results were correlated with biopsy-proven acute AMR in the first year and survival.ResultsPretransplant anti-HLA antibodies were present in 72 patients (25.7%) and 24 (8.6%) had DSA. There were 46 (16.4%) acute rejection episodes, 32 (11.4%) being cellular and 14 (5.0%) AMR. The incidence of acute AMR was higher in patients with pretransplant DSA (41.7%) than in those without (1.6%) (p < 0.001). The median cumulative MFI (cMFI) of the group DSA+/AMR+ was 5680 vs 2208 in DSA+/AMR− (p = 0.058). With univariate logistic regression a threshold value of 5280 cMFI was predictive for acute AMR. DSA cMFI’s ability to predict AMR was also explored by ROC analysis. AUC was 0.728 and the best threshold was a cMFI of 4340. Importantly pretransplant DSA > 5280 cMFI had a detrimental effect on 5-year graft survival.ConclusionsPreformed DSA cMFI values were clinically-relevant for the prediction of acute AMR and graft survival in kidney transplantation. A threshold of 4300–5300 cMFI was a significant outcome predictor.  相似文献

BackgroundHLA mismatching is a well known risk factor for worst outcomes in kidney transplantation.MethodsIn the present study, HLA antigen and eplet mismatches were determined in 151 living donor-recipient pairs transplanted between 2007 and 2014 and rejection episodes and graft survival were evaluated.ResultsWe found that high HLA-II eplet mismatch load (EpMM ≥ 13, versus low EpMM ≤ 5), was an independent predictor of AMR (adjusted HR = 14.839; P = 0.011), while HLA-II AgMM was not. We also showed that HLA-II EpMM load was a significant better predictor of AMR than AgMM (c-statistic = 0.064; P = 0.023). After discriminating HLA-II into HLA-DR and HLA-DQ loci we demonstrated that high versus low eplet mismatch load for HLA-DR (T3 ≥ 6 versus T = 0–1, p = 0.013) and HLA-DQ (T3 ≥ 7 versus T = 0–1, p = 0.009) are independent predictors for AMR.HLA-II EpMM increased discrimination performance of the classical HLA-II AgMM risk model (IDI, 0.061, 95%CI: 0.005–0.195) for AMR. Compared with AgMM, HLA-II eplet model adequately reclassified 13 of 17 patients (76.5%) with AMR and 92 of 134 patients (68.7%) without AMR (cfNRI, 0.785, 95%CI: 0.300–1.426).ConclusionsOur study evidences that eplet-based matching is a refinement of the classical HLA antigen mismatch analysis in LDKT and is a potential biomarker for personalized assessment of alloimmune risk.  相似文献

BackgroundCommensal Neisseria species (spp). represent an important reservoir of antimicrobial resistance genes for pathogenic Neisseria spp. In this systematic review, we aimed to assess the antimicrobial susceptibility of commensal Neisseria spp. and how this has evolved over time. We also aimed to assess if commensal Neisseria spp. showed intrinsic resistance to four antimicrobials - penicillin, azithromycin, ceftriaxone and ciprofloxacin.MethodsPubmed and Google Scholar were searched following the PRISMA guidelines. Articles reporting MICs of commensal Neisseria spp. were included according to inclusion/exclusion criteria, and the quality of the articles was assessed using a pre-designed tool. Individual and summary measures of penicillin, azithromycin, ceftriaxone and ciprofloxacin MICs were collected. Additional data was sought to perform a comparison between the MICs of pathogenic and commensal Neisseria spp.ResultsA total of 15 studies met our criteria.We found no evidence of intrinsic AMR in commensal Neisseria spp. We did find evidence of an increasing trend in MICs of commensal Neisseria spp. over time for all antimicrobials assessed. These findings were similar in various countries. Eight additional studies were included to compare pathogenic and commensal Neisseria spp.ConclusionThe MICs of commensal Neisseria spp. appear to be increasing in multiple countries. Surveillance of MICs in commensals could be used as an early warning system for antimicrobial resistance emergence in pathogens. Our findings underline the need for antibiotic stewardship interventions, particularly in populations with high antimicrobial consumption.  相似文献

BackgroundRoutine microbiology results are a valuable source of antimicrobial resistance (AMR) surveillance data in low- and middle-income countries (LMICs) as well as in high-income countries. Different approaches and strategies are used to generate AMR surveillance data.ObjectivesWe aimed to review strategies for AMR surveillance using routine microbiology results in LMICs and to highlight areas that need support to generate high-quality AMR data.SourcesWe searched PubMed for papers that used routine microbiology to describe the epidemiology of AMR and drug-resistant infections in LMICs. We also included papers that, from our perspective, were critical in highlighting the biases and challenges or employed specific strategies to overcome these in reporting AMR surveillance in LMICs.ContentTopics covered included strategies of identifying AMR cases (including case-finding based on isolates from routine diagnostic specimens and case-based surveillance of clinical syndromes), of collecting data (including cohort, point-prevalence survey, and case–control), of sampling AMR cases (including lot quality assurance surveys), and of processing and analysing data for AMR surveillance in LMICs.ImplicationsThe various AMR surveillance strategies warrant a thorough understanding of their limitations and potential biases to ensure maximum utilization and interpretation of local routine microbiology data across time and space. For instance, surveillance using case-finding based on results from clinical diagnostic specimens is relatively easy to implement and sustain in LMIC settings, but the estimates of incidence and proportion of AMR is at risk of biases due to underuse of microbiology. Case-based surveillance of clinical syndromes generates informative statistics that can be translated to clinical practices but needs financial and technical support as well as locally tailored trainings to sustain. Innovative AMR surveillance strategies that can easily be implemented and sustained with minimal costs will be useful for improving AMR data availability and quality in LMICs.  相似文献

BackgroundRapid initiation of antibiotic treatment is considered crucial in patients with severe infections such as septic shock and bacterial meningitis, but may not be as important for other infectious syndromes. A better understanding of which patients can tolerate a delay in start of therapy is important for antibiotic stewardship purposes.ObjectivesTo explore the existing evidence on the impact of time to antibiotics on clinical outcomes in patients presenting to the emergency department (ED) with bacterial infections of different severity of illness and source of infection.SourcesA literature search was performed in the PubMed/MEDLINE database using combined search terms for various infectious syndromes (sepsis/septic shock, bacterial meningitis, lower respiratory tract infections, urinary tract infections, intra-abdominal infections and skin and soft tissue infections), time to antibiotic treatment, and clinical outcome.ContentThe literature search generated 8828 hits. After screening titles and abstracts and assessing potentially relevant full-text papers, 60 original articles (four randomized controlled trials, 43 observational studies) were included. Most articles addressed sepsis/septic shock, while few studies evaluated early initiation of therapy in mild to moderate disease. The lack of randomized trials and the risk of confounding factors and biases in observational studies warrant caution in the interpretation of results. We conclude that the literature supports prompt administration of effective antibiotics for septic shock and bacterial meningitis, but there is no clear evidence showing that a delayed start of therapy is associated with worse outcome for less severe infectious syndromes.ImplicationsFor patients presenting with suspected bacterial infections, withholding antibiotic therapy until diagnostic results are available and a diagnosis has been established (e.g. by 4–8 h) seems acceptable in most cases unless septic shock or bacterial meningitis are suspected. This approach promotes the use of ecologically favourable antibiotics in the ED, reducing the risks of side effects and selection of resistance.  相似文献

ObjectiveAn epidemic of antibiotic allergy is occurring.Data SourcesArticles published since 2008.Study SelectionsArticles on antibiotic allergy and stewardship.ResultsA number of overlapping factors contribute. The most important factor is antibiotic overuse. Antibiotics are commonly used in situations in which no antibiotics are indicated. Thirty percent to 50% of ambulatory antibiotic use may be inappropriate. The duration of indicated antibiotic use is often excessive, which leads to more side effects. All antibiotic use can result in adverse reactions, and a fraction of these will be dutifully recorded as an allergy in the electronic health record (EHR). Most EHRs are not well structured to accurately convey information on expected side effects that have occurred, metabolic or other contraindications, dose-related or situational toxicities, personal preferences, clinically significant immunologically mediated hypersensitivity, and other reasons a particular patient may not want or should not be given a specific drug or type of drug in the future. As populations age, their accumulated baggage of reported antibiotic allergies increase. Suspected antibiotic allergy is rarely confirmed with appropriate testing or rechallenge. Patients then receive suboptimal antibiotic therapy and experience more side effects, treatment failures, and serious antibiotic-resistant infections. Reporting an antibiotic allergy in the EHR is nominally done to improve patient safety, but unfortunately, this is often not the actual result.ConclusionAudit and feedback, to help ensure adherence to Choosing Wisely recommendations and good antibiotic stewardship practices, can help reduce inappropriate antibiotic use. Restructuring EHRs to facilitate correct drug intolerance reporting, along with active antibiotic allergy delabeling programs, can help stem this epidemic.  相似文献
