Background: Clostridioides difficile infection (CDI) is a serious healthcare-associated infection responsible for >12,000 US deaths annually. Overtesting can lead to antibiotic overuse and potential patient harm when patients are colonized with C. difficile , but not infected, yet treated. National guidelines recommend when testing is appropriate; occasionally, guideline-noncompliant testing (GNCT) may be warranted. A multidisciplinary group at UNC Medical Center (UNCMC) including the antimicrobial stewardship program (ASP) used a best-practice alert in 2020 to improve diagnostic stewardship, to no effect. Evidence supports use of hard stops for this purpose, though less is known about provider acceptance. Methods: Beginning in May 2022, UNCMC implemented a hard stop in its electronic medical record system (EMR) for C. difficile GNCT orders, with exceptions to be approved by an ASP attending physician. Requests were retrospectively reviewed May–November 2022 to monitor for adverse patient outcomes and provider hard-stop compliance. The team exported data from the EMR (Epic Systems) and generated descriptive statistics in Microsoft Excel. Results: There were 85 GNCT orders during the study period. Most tests (62%) were reviewed by the ASP, and 38% sought non-ASP or no approval. Of the tests reviewed by the ASP, 33 (62%) were approved and 20 (38%) were not. Among tests not approved by the ASP, no patients subsequently received CDI-directed antibiotics, and 1 patient (5%) warranted same-admission CDI testing (negative). Of tests that circumvented ASP review, 18 (56%) ordering providers received a follow-up email from an associate chief medical officer to determine the rationale. No single response type dominated: 3 (17%) were unaware of the ASP review requirement, 2 (11%) indicated their patient’s uncharted refusal of laxatives, 2 (11%) indicated another patient-specific reason. Provider avoidance of the ASP approval mechanism decreased 38%, from 53% of noncompliant tests in month 1 to 33% of tests in month 6. Total tests orders dropped 15.5% from 1,129 during the same period in 2021 to 954 during the study period (95% CI, 13.4%–17.7%). Compliance with the guideline component requiring at least a 48-hour laxative-free interval prior to CDI testing increased from 85% (95% CI, 83%–87%) to 95% (95% CI, 93%–96%). CDI incidence rates decreased from 0.52 per 1,000 patient days (95% CI, 0.41–0.65) to 0.41 (95% CI, 0.32–0.53), though the change was neither significant at P = .05 nor attributable to any 1 intervention. Conclusions: Over time and with feedback to providers circumventing the exception process, providers accepted and used the hard stop, improving diagnostic stewardship and avoiding unneeded treatment.

背景:艰难梭菌感染(CDI)是一种严重的卫生保健相关感染,每年导致美国12,000人死亡。当患者被梭状芽胞杆菌定植,但未被感染,但尚未治疗时,过度检测可能导致抗生素的过度使用和潜在的患者伤害。国家指南建议何时进行适当的检测;偶尔,不符合指南的测试(GNCT)可能是必要的。北卡罗来纳大学医学中心(UNCMC)的一个多学科小组,包括抗菌剂管理计划(ASP),在2020年使用了最佳实践警报来改善诊断管理,但没有效果。有证据支持为此目的使用硬止流器,尽管对提供者的接受程度知之甚少。方法:从2022年5月开始,UNCMC在其电子病历系统(EMR)中实施了艰难梭菌GNCT订单的硬性停止,但由ASP主治医生批准的例外情况除外。回顾性审查了2022年5月至11月的请求,以监测不良患者结局和提供者硬停依从性。该团队从EMR (Epic Systems)导出数据,并在Microsoft Excel中生成描述性统计数据。结果:研究期间共有85个GNCT目。大多数测试(62%)由ASP审查,38%寻求非ASP或没有批准。在ASP审查的测试中,33项(62%)获得批准,20项(38%)未获得批准。在未被ASP批准的测试中,没有患者随后接受了CDI指导的抗生素,1名患者(5%)需要同一入院进行CDI测试(阴性)。在规避ASP审查的测试中,18家(56%)订购提供商收到了副首席医疗官的后续电子邮件,以确定理由。没有单一的反应类型占主导地位:3人(17%)不知道ASP审查要求,2人(11%)表示他们的患者未知地拒绝泻药,2人(11%)表示其他患者特有的原因。供应商对ASP审批机制的回避减少了38%,从第1个月53%的不合规测试减少到第6个月33%的不合规测试。总测试订单从2021年同期的1129个下降到研究期间的954个,下降了15.5% (95% CI, 13.4%-17.7%)。CDI检测前至少48小时无泻药间隔的指导成分依从性从85% (95% CI, 83%-87%)增加到95% (95% CI, 93%-96%)。CDI的发病率从0.52 / 1000患者日(95% CI, 0.41 - 0.65)下降到0.41 / 1000患者日(95% CI, 0.32-0.53),尽管变化在P = 0.05时并不显著,也不能归因于任何1次干预。结论:随着时间的推移和对规避例外流程的提供者的反馈,提供者接受并使用了硬停止,改善了诊断管理并避免了不必要的治疗。披露:没有

Background: With the emergence of new infectious diseases, infection control nursing (ICN) in hospitals has become increasingly significant. Consequently, research on ICN has been actively performed. We examined the knowledge structure and trends addressed in Korean ICN research. Methods: From 5 web-based Korean academic databases (DBpia, KISS, KMbase, KoreaMed, and RISS), 2,244 studies published between 2013 and 2022 were retrieved using ICN-related search terms (eg, “nurse” or “nursing” along with “infection control,” “infection prevention,” “healthcare-associated infection,” or “standard precautions”). After deleting duplicates, the authors assessed titles and abstracts and included 250 research abstracts in this study. Using NetMiner 4.4 software (Cyram, Seoul, Korea), words from abstracts of published articles were extracted and refined, then text network analysis and topic modeling were performed. A text network was structured based on the co-occurrence matrix of key words (semantic morphemes) and was analyzed to identify the main key words. Through topic modeling using the Latent Dirichlet Allocation algorithm, latent topics in the research abstracts were extracted. The authors verified the key words comprising the topic and the result of classifying the documents by topic and named topics. Results: The number of studies, which increased following the outbreak of Middle East respiratory syndrome in 2015, has declined over time but peaked in 2021 with the COVID-19 pandemic. The text network composed of the key words of the research abstracts was generated and visualized (Fig. 1). As a result of text network analysis, the 5 most common key words were ‘nurse,’ ‘infection control,’ ‘nursing care,’ ‘practice,’ and ‘perception’ in terms of degree and betweenness centrality. Other prominent main keywords were also identified: ‘knowledge,’ ‘compliance,’ ‘education,’ ‘intervention,’ ‘intention,’ and ‘safety.’ With the application of topic modeling to the research abstracts, 5 topics were derived and named as follows (Fig. 2): “infection control in nursing care for patient safety,” “infection control measures for healthcare personnel safety,” “burdens and obstacles for infection control among nurses,” “infection control for multidrug-resistant organisms,” and “knowledge, attitude, practice for infection control among nurses.” Conclusions: By applying text-network analysis and topic modeling, we obtained insights into Korean ICN research trends. To explore global ICN research trends, further study is necessary to analyze internationally published studies reflecting each country’s nursing work conditions. Disclosure: None
背景:随着新型传染病的出现,医院感染控制护理(ICN)变得越来越重要。因此,ICN的研究一直在积极进行。我们研究了韩国ICN研究的知识结构和趋势。方法:从5个基于网络的韩国学术数据库(DBpia、KISS、KMbase、KoreaMed和RISS)中,使用icn相关搜索词(例如,“护士”或“护理”以及“感染控制”、“感染预防”、“医疗保健相关感染”或“标准预防”)检索2013年至2022年间发表的2244项研究。在删除重复内容后,作者评估了标题和摘要,并将250篇研究摘要纳入本研究。使用NetMiner 4.4软件(Cyram, Seoul, Korea)对已发表文章摘要中的词语进行提取和提炼,然后进行文本网络分析和主题建模。基于关键词(语义语素)共现矩阵构建文本网络,并对其进行分析,识别主要关键词。利用Latent Dirichlet Allocation算法进行主题建模,提取研究摘要中的潜在主题。验证了构成主题的关键词以及按主题和命名主题对文献进行分类的结果。结果:2015年中东呼吸综合征爆发后,研究数量有所增加,但随着时间的推移,研究数量有所下降,但在2021年COVID-19大流行时达到顶峰。生成由研究摘要关键词组成的文本网络并将其可视化(图1)。通过文本网络分析,在程度和中间中心性方面,最常见的5个关键词是“护士”、“感染控制”、“护理”、“实践”和“感知”。其他突出的关键词还包括:“知识”、“遵守”、“教育”、“干预”、“意图”和“安全”。将主题建模应用于研究摘要,得出5个主题,命名如下(图2):“护理中的感染控制对患者安全的影响”、“医护人员安全的感染控制措施”、“护士感染控制的负担与障碍”、“耐多药菌感染控制”、“护士感染控制的知识、态度与实践”。结论:通过文本网络分析和主题建模,我们了解了韩国ICN的研究趋势。为探究全球ICN研究趋势,有必要进一步分析国际上发表的反映各国护理工作状况的研究。披露:没有

Background: Recent evidence has shown that the updated COVID-19 bivalent booster is effective in preventing COVID-19 compared with no previous vaccination and prior monovalent vaccination. Despite its effectiveness, uptake has been poor, and a minority of eligible recipients have received the booster. Understanding healthcare worker (HCW) attitudes for and against voluntary uptake of the bivalent booster dose against COVID-19 can help guide communication strategy to maximize uptake. In this survey study, we investigated attitudes toward updated and/or bivalent booster uptake in a behavioral health hospital shortly after a COVID-19 outbreak. Methods: A survey tool was developed and sent to all HCWs at the Yale New Haven Psychiatric Hospital in December 2022. The survey queried demographic data, job category, history of COVID-19, prior COVID-19 vaccinations, perception of COVID-19 exposure, and updated and/or bivalent booster doses. The survey was administered several weeks after a COVID-19 outbreak on multiple inpatient behavioral health units. Receipt of the COVID-19 primary vaccination series and the first booster dose were mandated for HCWs; however, receipt of the bivalent booster was voluntary. Results: The survey was sent to 664 HCWs with primary assignments in behavioral health settings. In total, 182 (27.4%) provided complete responses to the survey and are included in these data. Moreover, 91 HCWs (50.0%) reported previously having COVID-19 at least once. Overall, 100 HCWs (55.0%) received the bivalent booster. The most identified reasons for receiving the bivalent booster were wanting to protect family and friends (n = 113), importance of staying healthy (n = 112), and protecting colleagues and patients (n = 103). The most identified reasons for not wanting to receive the bivalent booster dose were not thinking it provides additional protection (n = 33), “too many” shots already received (n = 31), and concern about side effects (n = 30). Discussion: Bivalent booster dose uptake in HCWs on behavioral health units shortly after a COVID-19 outbreak was greater than the general population. HCWs reported varying reasons for and against receipt of the bivalent booster dose, with the most common being protection of family and friends and perceptions of no additional protection, respectively. A limitation of this study was voluntary response bias, in which results are biased toward individuals more likely to receive a bivalent booster vaccine. It is unclear whether reasons for declining the vaccine are representative of HCWs who did not complete the survey. Assessing attitudes for the bivalent booster dose can assist in guiding communication and outreach strategies to increase vaccine uptake by HCWs. Disclosures: None
背景:最近的证据表明,与之前未接种疫苗和之前接种过单价疫苗相比,更新后的COVID-19二价增强疫苗可有效预防COVID-19。尽管它有效,但使用率很低,少数符合条件的接受者已经接种了加强剂。了解卫生保健工作者对自愿接种COVID-19二价加强剂的态度和反对态度有助于指导宣传策略,以最大限度地提高接种效果。在这项调查研究中,我们调查了行为健康医院在COVID-19爆发后不久对更新和/或二价增强剂摄取的态度。方法:开发一种调查工具,并于2022年12月向耶鲁大学纽黑文精神病院的所有HCWs发送调查工具。该调查询问了人口统计数据、工作类别、COVID-19史、之前的COVID-19疫苗接种、对COVID-19暴露的认知以及更新和/或二价加强剂量。这项调查是在多个住院行为健康单位爆发COVID-19疫情几周后进行的。卫生保健工作者必须接种COVID-19初级疫苗系列和第一剂加强疫苗;然而,接受二价增强剂是自愿的。结果:该调查被发送给664名主要在行为卫生机构工作的卫生保健工作者。共有182家(27.4%)对调查提供了完整的答复,并纳入了这些数据。此外,91名医护人员(50.0%)报告曾至少感染过一次COVID-19。总体而言,100名HCWs(55.0%)接受了二价增强剂。最明确的接受二价增强疫苗的原因是希望保护家人和朋友(n = 113),保持健康的重要性(n = 112),以及保护同事和患者(n = 103)。不想接种二价加强剂的最明确原因是认为它不能提供额外的保护(n = 33),“太多”已经接种(n = 31),以及担心副作用(n = 30)。讨论:在COVID-19爆发后不久,行为卫生单位的卫生保健工作者的双价加强剂摄入量大于一般人群。卫生保健工作者报告了支持和反对接受二价加强剂的各种原因,最常见的分别是为了保护家人和朋友,以及认为没有额外的保护。本研究的一个局限性是自愿反应偏倚,其中结果偏向于更有可能接受二价加强疫苗的个体。目前尚不清楚拒绝接种疫苗的原因是否代表未完成调查的卫生保健工作者。评估对二价加强剂的态度有助于指导沟通和推广战略,以增加卫生保健工作者对疫苗的吸收。披露:没有

Fear of missing organisms (FOMO): Diabetic foot and osteomyelitis management opportunities 害怕生物丢失(FOMO):糖尿病足和骨髓炎管理机会
Pub Date : 2023-06-01 DOI: 10.1017/ash.2023.212

Background: Hospitalizations for diabetic foot infections and lower-extremity osteomyelitis are common. Use of empiric antibiotic therapy for methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa is also common. Guidelines recommend antibiotic therapy based on severity of illness, risk factors for MRSA and P. aeruginosa , and local prevalence. We evaluated the concordance between empiric antibiotic therapy and both culture results and definitive antibiotic therapy with a focus on MRSA and P. aeruginosa . We also evaluated how well MRSA and pseudomonal risk factors were predictive of culture results with these organisms. Methods: We conducted a cohort study of all patients admitted to our hospital system in 2021 with a diagnosis of a diabetic foot infection or lower-extremity osteomyelitis. Patients were included if they had an International Classification of Disease, Tenth Revision (ICD-10) diagnosis code of M86, E10.621, E11.621, or E08.621. Patients were excluded if antibiotics were for another indication or if they were aged <18 years. In patients with multiple hospitalizations only the first hospitalization was included. Empiric antibiotic therapy included antibiotics started by the admitting team. Definitive antibiotic therapy included the final antibiotic course either completed during admission or prescribed at the time of discharge. MRSA risk factors included prior positive culture with MRSA within the last year, hospitalization with IV antibiotics within 90 days, intravenous drug use, or hemodialysis. Pseudomonal risk factors included prior positive culture with P. aeruginosa within the last year or hospitalization with IV antibiotics within 90 days. Results: In 2021, 260 unique patients were admitted with suspected diabetic foot infections or lower-extremity osteomyelitis. 68 patients had >1 admission. Empiric anti-MRSA and antipseudomonal therapy was administered to 224 (86%) and 214 (82%) patients, respectively. Definitive anti-MRSA and antipseudomonal therapy was administered to 76 (30%) and 51 (20%) patients, respectively. Of the 195 patients who had wound cultures, 29 (15%) and 18 (9%) had positive cultures for MRSA and P. aeruginosa respectively (Fig.). The negative predictive value of MRSA risk factors for predicting a negative culture with MRSA was 91%. The negative predictive value of pseudomonal risk factors for predicting a negative culture with P. aeruginosa was 95%. Conclusions: Our data suggest an opportunity for substantial reductions in empiric anti-MRSA and antipseudomonal therapy for diabetic foot infection and lower-extremity osteomyelitis.

背景:糖尿病足感染和下肢骨髓炎住院是常见的。使用经验性抗生素治疗耐甲氧西林金黄色葡萄球菌(MRSA)和铜绿假单胞菌也很常见。指南根据疾病的严重程度、MRSA和铜绿假单胞菌的危险因素以及当地流行情况推荐抗生素治疗。我们评估了经验性抗生素治疗与培养结果和最终抗生素治疗之间的一致性,重点是MRSA和铜绿假单胞菌。我们还评估了MRSA和假单胞菌风险因素对这些微生物培养结果的预测程度。方法:我们对2021年所有诊断为糖尿病足感染或下肢骨髓炎的住院患者进行了一项队列研究。如果患者患有国际疾病分类第十版(ICD-10)诊断代码为M86、E10.621、E11.621或E08.621,则纳入患者。如果抗生素用于其他适应症或年龄为18岁,则排除患者。在多次住院的患者中,仅包括第一次住院。经验性抗生素治疗包括由入院小组开始使用的抗生素。最终抗生素治疗包括在入院时完成或出院时规定的最终抗生素疗程。MRSA危险因素包括过去一年内MRSA阳性培养,90天内静脉注射抗生素住院,静脉注射药物或血液透析。假单胞菌的危险因素包括过去一年内铜绿假单胞菌培养阳性或90天内静脉注射抗生素住院。结果:2021年,260例疑似糖尿病足感染或下肢骨髓炎的独特患者入院。68例患者住院1次。分别对224例(86%)和214例(82%)患者进行经验性抗mrsa和抗假单胞菌治疗。分别对76例(30%)和51例(20%)患者进行了明确的抗mrsa和抗假单胞菌治疗。在195例进行伤口培养的患者中,分别有29例(15%)和18例(9%)的MRSA和P. aeruginosa培养呈阳性(图)。MRSA危险因素预测MRSA阴性培养的阴性预测值为91%。假单胞菌危险因素预测铜绿假单胞菌阴性培养的阴性预测值为95%。结论:我们的数据表明,糖尿病足感染和下肢骨髓炎的经验性抗mrsa和抗假单胞菌治疗有机会大幅减少。耐甲氧西林金黄色葡萄球菌和假单胞菌危险因素的缺失在预测这些微生物的阳性培养缺失方面是相当好的。披露:没有

Use of empiric antibiotic therapy for methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa is also common. Guidelines recommend antibiotic therapy based on severity of illness, risk factors for MRSA and P. aeruginosa , and local prevalence. We evaluated the concordance between empiric antibiotic therapy and both culture results and definitive antibiotic therapy with a focus on MRSA and P. aeruginosa . We also evaluated how well MRSA and pseudomonal risk factors were predictive of culture results with these organisms. Methods: We conducted a cohort study of all patients admitted to our hospital system in 2021 with a diagnosis of a diabetic foot infection or lower-extremity osteomyelitis. Patients were included if they had an International Classification of Disease, Tenth Revision (ICD-10) diagnosis code of M86, E10.621, E11.621, or E08.621. Patients were excluded if antibiotics were for another indication or if they were aged <18 years. In patients with multiple hospitalizations only the first hospitalization was included. Empiric antibiotic therapy included antibiotics started by the admitting team. Definitive antibiotic therapy included the final antibiotic course either completed during admission or prescribed at the time of discharge. MRSA risk factors included prior positive culture with MRSA within the last year, hospitalization with IV antibiotics within 90 days, intravenous drug use, or hemodialysis. Pseudomonal risk factors included prior positive culture with P. aeruginosa within the last year or hospitalization with IV antibiotics within 90 days.

Background: Multidrug-resistant bacteria are of high concern, and empiric antimicrobial choice for infections caused by these pathogens, while awaiting susceptibilities, is increasingly encountered. We describe the susceptibility patterns of ceftazidime-avibactam (CZA), imipenem-rel-ebactam (I-R), meropenem-vaborbactam (MVB), cefiderocol (FDC), ceftolozone-tazobactam (C/T), minocycline (MIN), and tigecycline (TGC) for carbapenem-resistant Enterobacterales at an academic medical center. Methods: We performed a single-center analysis of Enterobacterales isolates from 110 hospitalized adult patients who had CZA, I-R, MVB, FDC, MIN, or TGC susceptibility testing performed between October 2020 and September 2022. The study included 1 isolate per patient per infection site per year. Isolates were divided into carbapenem susceptible and non susceptible categories. For carbapenem nonsusceptible isolates, phenotypic confirmatory testing of carbapenem nonsusceptibility was performed using disk diffusion, gradient diffusion, and/or broth microdilution. Interpretive categories were applied using CLSI- or FDA-approved break-points where applicable. Carbapenemase testing was also performed using the modified carbapenem inactivation method (mCIM) and, where applicable, this testing was confirmed at the Massachusetts State Public Health Laboratory using genotypic methods. Results: In total, 125 unique isolates were reviewed: 34 meropenem-susceptible and 91 meropenem-intermediate or resistant isolates. CZA, I-R, MVB, and FDC were active against all tested meropenem-susceptible isolates; however, 50% of tested isolates were susceptible to C/T. MIN and TGC, when tested, were active against 2 of 11 isolates (18%) and 14 of 16 isolates (86%), respectively. Of 91 meropenem-nonsusceptible isolates, most tested isolates were susceptible to MVB (59 of 72, 82%), followed by CZA (63 of 82, 77%), I-R (8 of 11, 73%), FDC (9 of 16, 56%), and C/T (1 of 12, 8%). TGC retained activity against 78 of 81 (96%) tested isolates. In contrast, MIN retained activity against 8 of 45 isolates (18%). Additionally, all (28 of 28, 100%) isolates that were nonsusceptible to at least 1 novel agent (CZA, I-R, MVB, FDC, or C/T) remained susceptible to TGC. State laboratory confirmatory testing was available for 75 isolates. Of 43 mCIM-positive isolates, all 28 KPC-producing isolates were susceptible to CZA, I-R, MVB, FDC and TGC. Conclusions: Among Enterobacterales, CZA, MVB, and I-R retained activity against most non-NDM CRE isolates in this local analysis, with comparable susceptibilities. TGC demonstrated excellent susceptibility for CRE and meropenem-susceptible isolates, offering an alternative for nonbloodstream infections. Choice of empiric agent with a newβ-lactam, β-lactam–β-lactamase inhibitors, or TGC appear to be reasonable empiric therapeutic options at our institution.

背景:耐多药细菌是高度关注的问题,在等待药物敏感性的同时,越来越多地遇到由这些病原体引起的感染的经验性抗菌药物选择。我们在一个学术医疗中心描述了头孢他啶-阿维巴坦(CZA)、亚胺培南-雷-伊巴坦(I-R)、美罗培南-瓦波巴坦(MVB)、头孢地罗col (FDC)、头孢托酮-他唑巴坦(C/T)、米诺环素(MIN)和替加环素(TGC)对碳青霉烯耐药肠杆菌的敏感性模式。方法:我们对2020年10月至2022年9月期间接受CZA、I-R、MVB、FDC、MIN或TGC药敏试验的110名住院成年患者的肠杆菌分离株进行了单中心分析。该研究包括每年每个感染部位每位患者1株分离株。分离株分为碳青霉烯类敏感株和非敏感株。对于碳青霉烯不敏感的分离株,采用圆盘扩散、梯度扩散和/或肉汤微量稀释进行碳青霉烯不敏感的表型验证试验。解释性分类在适用的情况下使用CLSI或fda批准的断点。碳青霉烯酶检测也使用改良的碳青霉烯酶失活法(mCIM)进行,在适用的情况下,该检测在马萨诸塞州公共卫生实验室使用基因型方法得到证实。结果:共鉴定出125株独特的分离株:34株美罗培尼敏感,91株美罗培尼中等或耐药。CZA、I-R、MVB和FDC对所有美罗培南敏感菌株均有活性;然而,50%的测试分离株对C/T敏感。经检测,MIN和TGC分别对11个分离株中的2个(18%)和16个分离株中的14个(86%)有活性。91株美罗培尼不敏感的分离株中,大多数对MVB敏感(72 / 82%),其次是CZA(82 / 77%)、I-R(11 / 73%)、FDC(16 / 56%)和C/T(1 / 12.8%)。TGC对81个分离株中的78个(96%)保持活性。相比之下,MIN对45个分离株中的8个(18%)保持活性。此外,所有(28 / 28,100%)对至少1种新药物(CZA, I-R, MVB, FDC或C/T)不敏感的分离株仍然对TGC敏感。对75株分离株进行了国家实验室确认检测。43株mcim阳性分离株中,28株产kpc的分离株均对CZA、I-R、MVB、FDC和TGC敏感。结论:在肠杆菌中,CZA、MVB和I-R对大多数非ndm CRE分离株保持活性,敏感性相当。TGC对CRE和美罗培宁敏感的分离株表现出极好的敏感性,为非血流感染提供了另一种选择。选择新的β-内酰胺、β-内酰胺- β-内酰胺酶抑制剂或TGC似乎是我们机构合理的经验性治疗选择。由于美罗培南不敏感的分离株的低敏感性,CT和MIN在使用前需要进行确认性检测。披露:没有

Background: The CDC’s new Public Health Strategies to Prevent the Spread of Novel and Targeted Multidrug-Resistant Organisms (MDROs) were informed by mathematical models that assessed the impact of implementing preventive strategies directed at a subset of healthcare facilities characterized as influential or highly connected based on their predicted role in the regional spread of MDROs. We developed an interactive tool to communicate mathematical modeling results and visualize the regional patient transfer network for public health departments and healthcare facilities to assist in planning and implementing prevention strategies. Methods: An interactive RShiny application is currently hosted in the CDC network and is accessible to external partners through the Secure Access Management Services (SAMS). Patient transfer volumes (direct and indirect, that is, with up to 30 days in the community between admissions) were estimated from the CMS fee-for-service claims data from 2019. The spread of a carbapenem-resistant Enterobacterales (CRE)–like MDROs within a US state was simulated using a deterministic model with susceptible and infectious compartments in the community and healthcare facilities interconnected through patient transfers. Individuals determined to be infectious through admission screening, point-prevalence surveys (PPSs), or notified from interfacility communication were assigned lower transmissibility if enhanced infection prevention and control practices were in place at a facility. Results: The application consists of 4 interactive tabs. Users can visualize the statewide patient-sharing network for any US state and select territories in the first tab (Fig. 1). A feature allows users to highlight a facility of interest and display downstream or upstream facilities that received or sent transfers from the facility of interest, respectively. A second tab lists influential facilities to aid in prioritizing screening and prevention activities. A third tab lists all facilities in the state in descending order of their dispersal rate (ie, the rate at which patients are shared downstream to other facilities), which can help identify highly connected facilities. In the fourth tab, an interactive graph displays the predicted reduction of MDRO prevalence given a range of intervention scenarios (Fig. 2). Conclusions: Our RShiny application, which can be accessed by public health partners, can assist healthcare facilities and public health departments in planning and tailoring MDRO prevention activity bundles.

背景:美国疾病控制与预防中心的新公共卫生战略,以防止新型和靶向多药耐药生物(MDROs)的传播,是通过数学模型来评估实施预防战略的影响,这些战略针对具有影响力或高度联系的医疗机构子集,基于它们在MDROs区域传播中的预测作用。我们开发了一个互动工具,用于交流数学建模结果,并将公共卫生部门和医疗机构的区域患者转移网络可视化,以协助规划和实施预防策略。方法:一个交互式RShiny应用程序目前托管在CDC网络中,外部合作伙伴可以通过安全访问管理服务(SAMS)访问它。从2019年的CMS服务收费索赔数据中估计了患者转诊量(直接和间接,即入院之间在社区停留最多30天)。使用确定性模型模拟了美国州内碳青霉烯类耐药肠杆菌(CRE)样mdro的传播,该模型在社区和医疗机构中通过患者转移相互连接的易感室和感染性室。如果在设施中加强感染预防和控制措施,则通过入院筛查、点流行调查(PPSs)或设施间通信通知确定具有传染性的个体被分配为较低的传播力。结果:该应用程序由4个交互式选项卡组成。用户可以可视化美国任何州的全州患者共享网络,并在第一个选项卡中选择地区(图1)。一个功能允许用户突出显示感兴趣的设施,并显示分别从感兴趣的设施接收或发送转移的下游或上游设施。第二个标签列出了有助于确定筛查和预防活动优先次序的有影响力的设施。第三个标签列出了该州所有的医疗机构,按照它们的分散率(即,病人共享到下游其他医疗机构的比率)降序排列,这有助于识别高度连接的医疗机构。在第四个选项卡中,一个交互式图表显示了在一系列干预方案下MDRO患病率的预测降低(图2)。结论:我们的RShiny应用程序可以由公共卫生合作伙伴访问,可以帮助医疗机构和公共卫生部门规划和定制MDRO预防活动包。披露:没有

Background: Community-acquired pneumonia (CAP) is a common indication for antibiotic prescribing in hospitalized patients. Professional societies’ clinical guidelines recommend specific antibiotics for empiric treatment of CAP based on clinical factors. Manual assessments of appropriateness are time-consuming and are often conducted on a smaller scale. We evaluated empiric antibiotic selection among a large cohort of adults hospitalized with CAP using electronic health records. Methods: In this study, we used the PINC-AI healthcare database to define a cohort of adults hospitalized with CAP from 2013 to 2020. CAP was identified by International Classification of Diseases (ICD) diagnosis codes. Exclusions were applied to identify uncomplicated CAP (Fig. 1). Treatment was only evaluated if a chest radiograph or computerized tomography (CT) scan was charged during the first 2 days of hospitalization, otherwise it was considered an inadequate CAP evaluation. Administrative billing data were used to identify antibiotics charged within the first 2 days of hospitalization. Empiric guideline-recommended treatment was determined based on 2019 CAP guidelines and more recent studies. Patients who received nonrecommended treatment were evaluated for antibiotic allergies in the current hospitalization or methicillin-resistant Staphylococcus aureus (MRSA) colonization or infection in the year prior or on admission using International Classification of Disease, Tenth Revision (ICD-10) diagnosis codes. Results: We identified 4.47 million adult hospitalizations with CAP from 2013 to 2020; 32% (1.43 million) were included in this analysis (Fig. 1). Among discharges with adequate CAP evaluation (1.37 million), 59.7% received recommended antibiotics in the first 2 days of hospitalization, ranging from 62.6% in 2013 to 57.5% in 2019. Overall, 34.8% of our study population received a nonrecommended antibiotic without documentation of an antibiotic allergy or MRSA colonization (2013: 32.5%; 2018: 36.7%) (Fig. 2). Most patients in our study population received >1 antibiotic (92.3%) in the first 2 days of hospitalization. The most common antibiotics among patients receiving recommended treatment were ceftriaxone (74.2% of patients receiving recommended treatment), azithromycin (67.2%), and levofloxacin (31.8%) (Fig. 3a). The most common nonrecommended antibiotics were vancomycin (57.2% of patients receiving nonrecommended treatment), piperacillin-tazobactam (48.1%), and cefepime (25.7%) (Fig. 3b). From 2013 to 2020, cefepime charges consistently increased among CAP patients treated with nonrecommended antibiotics, whereas levofloxacin charges consistently decreased among CAP patients treated with only recommended antibiotics. Conclusions: Approximately one-third of patients with uncomplicated CAP received nonrecommended empiric antibiotics, and from 2013 to 2020 that proportion increased by 9%. Additional strategies are needed to help identify opportunities to optimiz
背景:社区获得性肺炎(CAP)是住院患者抗生素处方的常见指征。专业协会的临床指南根据临床因素推荐经验性治疗CAP的特定抗生素。对适当性进行人工评估是费时的,而且往往规模较小。我们使用电子健康记录评估了大量因CAP住院的成人的经验性抗生素选择。方法:在本研究中,我们使用pic - ai医疗保健数据库来定义2013年至2020年住院的成人CAP队列。CAP由国际疾病分类(ICD)诊断代码确定。排除病例用于识别无并发症的CAP(图1)。只有在住院前2天内进行胸片或计算机断层扫描(CT)扫描时才对治疗进行评估,否则视为CAP评估不充分。使用行政计费数据来确定住院前2天内收取的抗生素。经验性指南推荐的治疗方法是根据2019年CAP指南和最近的研究确定的。使用国际疾病分类第十版(ICD-10)诊断代码评估接受非推荐治疗的患者当前住院期间的抗生素过敏或入院前一年或入院时耐甲氧西林金黄色葡萄球菌(MRSA)定植或感染情况。结果:从2013年到2020年,我们确定了447万成人CAP住院;32%(143万)纳入本分析(图1)。在CAP评估充分的出院患者(137万)中,59.7%的患者在住院前2天内接受了推荐的抗生素治疗,从2013年的62.6%到2019年的57.5%不等。总体而言,34.8%的研究人群接受了非推荐抗生素,没有抗生素过敏或MRSA定植的记录(2013年:32.5%;2018年:36.7%)(图2)。在我们的研究人群中,大多数患者在住院前2天使用了1种抗生素(92.3%)。在接受推荐治疗的患者中,最常见的抗生素是头孢曲松(74.2%)、阿奇霉素(67.2%)和左氧氟沙星(31.8%)(图3a)。最常见的非推荐抗生素是万古霉素(57.2%接受非推荐治疗的患者)、哌拉西林-他唑巴坦(48.1%)和头孢吡肟(25.7%)(图3b)。从2013年到2020年,在非推荐抗生素治疗的CAP患者中,头孢吡肟费用持续增加,而在仅推荐抗生素治疗的CAP患者中,左氧氟沙星费用持续下降。结论:大约三分之一的无并发症CAP患者接受了非推荐的经验性抗生素治疗,从2013年到2020年,这一比例增加了9%。需要额外的策略来帮助确定优化CAP患者抗生素选择的机会。披露:无

Overall, 34.8% of our study population received a nonrecommended antibiotic without documentation of an antibiotic allergy or MRSA colonization (2013: 32.5%; 2018: 36.7%) (Fig. 2). Most patients in our study population received &gt;1 antibiotic (92.3%) in the first 2 days of hospitalization. The most common antibiotics among patients receiving recommended treatment were ceftriaxone (74.2% of patients receiving recommended treatment), azithromycin (67.2%), and levofloxacin (31.8%) (Fig. 3a). The most common nonrecommended antibiotics were vancomycin (57.2% of patients receiving nonrecommended treatment), piperacillin-tazobactam (48.1%), and cefepime (25.7%) (Fig. 3b). From 2013 to 2020, cefepime charges consistently increased among CAP patients treated with nonrecommended antibiotics, whereas levofloxacin charges consistently decreased among CAP patients treated with only recommended antibiotics. Conclusions: Approximately one-third of patients with uncomplicated CAP received nonrecommended empiric antibiotics, and from 2013 to 2020 that proportion increased by 9%.

Background: Candida auris is an emerging pathogen that exhibits broad antimicrobial resistance and causes highly morbid infections. Prolonged survival on surfaces has been demonstrated, and standard disinfectants may not achieve adequate disinfection. Persistent patient colonization and constant environmental recontamination poses an infection risk that may be mitigated by no touch disinfection systems. We evaluated the efficacy of continuous dry hydrogen peroxide (DHP) exposure on C. auris environmental contamination. Methods: The study was conducted in a large tertiary-care center where multiple patients were identified as either infected or colonized with C. auris . DHP-emitting systems were installed in the ventilation systems dedicated to the adult burn intensive care and children’s cardiac intensive care units. Composite surface samples were collected in a sample of patient rooms and shared clinical workspaces among units with current C. auris patients, before and after installation of the DHP system, and from areas with and without exposure to DHP. The samples included “high touch” surfaces near the patient, the general area of the patient room, shared medical equipment for the unit, shared staff work areas, and equipment dedicated to individual staff members (Table 1). Presence of C. auris was determined by polymerase chain reaction (PCR). Association between DHP exposure and C. auris contamination was determined using the Fisher exact test. Results: In the presence of C. auris patients, 5 baseline samples per unit were taken before DHP was installed, and then 5 samples per unit were taken on days 7, 14, and 28 after installation. Prior to initiation of DHP, 7 (70%) of 10 samples were PCR positive for C. auris . After DHP installation, a statistically significant decrease to 5 (16.7%) of 30 samples ( P <.05) was observed. In total, 20 samples (5 before installation and 15 after installation) were collected from units without DHP on the same days. At baseline, 2 (40%) of 5 samples were PCR positive for C. auris . During subsequent periods, 4 (27%) 15 samples were positive ( P = .66). No adverse effects were reported by patients, visitors, or personnel in association with the operation of the DHP systems. Conclusions: These findings suggest that DHP is effective in reducing surface C. auris contamination in a variety of patient and healthcare worker surfaces. Disclosures: None
背景:耳念珠菌是一种新兴的病原体,表现出广泛的抗微生物药物耐药性并引起高度病态的感染。已证明在表面上存活时间长,标准消毒剂可能无法达到充分的消毒效果。持续的患者定植和持续的环境再污染构成感染风险,可通过无接触消毒系统减轻感染风险。我们评估了连续干燥过氧化氢(DHP)暴露对金黄色葡萄球菌环境污染的影响。方法:该研究是在一个大型三级保健中心进行的,其中多名患者被确定为感染或定植了金黄色葡萄球菌。在成人烧伤重症监护病房和儿童心脏重症监护病房专用的通风系统中安装了dhp排放系统。在安装DHP系统之前和之后,以及在暴露于DHP和未暴露于DHP的地区,在现有auris患者的单位之间的病房和共用临床工作空间的样本中收集复合表面样本。样本包括患者附近的“高接触”表面、病房的一般区域、共用医疗设备、共用工作人员工作区和专用于个人工作人员的设备(表1)。通过聚合酶链反应(PCR)确定了金黄色葡萄球菌的存在。使用Fisher精确试验确定DHP暴露与耳球菌污染之间的关系。结果:在auris患者存在的情况下,DHP安装前每单位采集5个基线样本,安装后第7、14、28天每单位采集5个样本。DHP开始前,10份样品中有7份(70%)为金黄色葡萄球菌PCR阳性。安装DHP后,30个样品中有5个(16.7%)下降,具有统计学意义(P < 0.05)。当天共从未安装DHP的机组中采集20个样品(安装前5个,安装后15个)。在基线时,5个样本中有2个(40%)为金黄色葡萄球菌PCR阳性。在随后的时间里,4(27%)15个样本呈阳性(P = 0.66)。患者、访客或与DHP系统操作相关的人员均未报告不良反应。结论:这些发现表明DHP可有效减少各种患者和医护人员表面的耳c菌污染。披露:没有

Background: Candida auris , an emerging fungal pathogen, is frequently drug resistant and spreads rapidly in healthcare facilities. Screening to identify patients colonized with C. auris can prevent further spread by prompting aggressive infection prevention and control measures. The CDC recommends C. auris screening based on local epidemiological conditions, patient characteristics, and facility-level risk factors; such screening might help facilities in higher burden areas to mitigate transmission and those in lower-burden areas to detect new introductions before spread begins. To describe US screening practices and challenges, we surveyed a network of infection disease practitioners, comparing responses by local C. auris case burdens. Methods: In August 2022, we emailed a survey about C. auris screening practices to ~3,000 members of the IDSA Emerging Infection Network. We describe survey results, stratifying findings by whether the healthcare facility was in a region where C. auris is frequently identified (tier 3 facility) or not frequently identified (tier 2 facility), based on CDC assessment using existing multidrug-resistant organism containment guidance (https://www.cdc.gov/hai/containment/guidelines.html). Results: We received 253 responses (tier 3 facilities: 119, tier 2 facilities: 134); overall, 37% performed screening. Tier 3 facilities more frequently performed screening than tier 2 facilities (59% vs 17%). Among facilities that performed screening, tier 3 facilities, compared with tier 2 facilities, more frequently screened patients on admission (84% vs 55%) and used an in-house laboratory for testing (68% vs 29%), most often with culture-based methods. Tier 2 facilities more frequently screened patients already admitted in the facility (eg, in response to cases or as part of point-prevalence surveys) compared with tier 3 facilities (59% vs 49%). Among facilities performing screening, 72% had identified ≥1 case in the previous year (tier 3 facilities, 85%; tier 2 facilities, 33%). Barriers to screening included limited laboratory capacity, long testing turnaround times, and the perception that screening was not useful. Conclusions: Most facilities surveyed did not perform C. auris screening. However, most facilities that performed screening, including those in regions of higher and lower C. auris burden, detected cases during the previous year. Admission screening, which might help detect new introductions before spread begins, was uncommon in facilities in lower-burden areas. Improving ease of C. auris screening through access to in-house laboratory testing with rapid turnaround times might increase the adoption of C. auris screening by facilities, thereby increasing detection and preventing spread. Disclosures: None
背景:耳念珠菌是一种新兴的真菌病原体,经常耐药并在卫生保健机构中迅速传播。筛查金黄色葡萄球菌定植的患者可通过采取积极的感染预防和控制措施来防止进一步传播。疾病预防控制中心建议根据当地流行病学情况、患者特征和设施级别的风险因素进行金黄色葡萄球菌筛查;这种筛查可能有助于高负担地区的设施减轻传播,并有助于低负担地区的设施在传播开始之前发现新的传入。为了描述美国的筛查实践和挑战,我们调查了一个传染病从业人员网络,比较了当地金黄色葡萄球菌病例负担的反应。方法:在2022年8月,我们通过电子邮件向IDSA新兴感染网络的约3000名成员发送了一份关于C. auris筛查实践的调查。我们描述了调查结果,根据疾病预防控制中心使用现有的耐多药生物控制指南(https://www.cdc.gov/hai/containment/guidelines.html)进行的评估,根据医疗机构是否位于经常发现金黄色葡萄球菌的地区(3级设施)或不经常发现的地区(2级设施),对调查结果进行了分层。结果:我们收到253份回复(3级机构:119份,2级机构:134份);总体而言,37%的人进行了筛查。三级医疗机构比二级医疗机构更频繁地进行筛查(59%对17%)。在进行筛查的机构中,三级机构与二级机构相比,更频繁地在入院时对患者进行筛查(84%对55%),并使用内部实验室进行检测(68%对29%),最常用的是基于培养的方法。与三级设施相比,二级设施更频繁地对已经入院的患者进行筛查(例如,响应病例或作为点患病率调查的一部分)(59%对49%)。在进行筛查的机构中,72%在前一年发现了≥1例病例(三级机构,85%;二级设施,33%)。筛选的障碍包括实验室能力有限,测试周转时间长,以及认为筛选没有用处。结论:大多数调查机构没有进行耳球菌筛查。然而,大多数进行筛查的设施,包括耳c菌负担较高和较低地区的设施,在前一年发现了病例。入院检查可能有助于在传播开始前发现新的传入,但在负担较轻地区的设施中并不常见。通过获得快速周转时间的内部实验室检测来改善auris筛查的便利性,可能会增加设施对auris筛查的采用,从而增加检测和防止传播。披露:没有

Approach for sustainable district-led production and distribution of alcohol-based hand rub in Uganda 在乌干达以地区为主导的可持续生产和销售含酒精洗手液的办法
Pub Date : 2023-06-01 DOI: 10.1017/ash.2023.224

Background: A sustainable, continuous supply of alcohol-based hand rub (ABHR) is essential for healthcare workers in health facilities. The WHO provides guidance for production in individual health facilities. In Uganda, using this guidance, an innovative approach was implemented at the district local government level to produce and subsequently distribute ABHR to primary-care health facilities that have limited capacity for local facility-level production. This project was supported by the CDC in collaboration with the Infectious Diseases Institute (IDI) and targeted governmental or district engagement with local partners to ensure sustainability. Methods: District stakeholders were engaged to obtain buy-in and define roles and responsibilities. Overall, 4 staff members in each of 6 supported districts were nominated by District Health Officers for training: 2 staff members were trained to produce ABHR and conduct internal quality control and 2 were trained on external quality control. Districts provided ABHR production-unit facilities and facilitated integration within the government essential supplies delivery system, National Medical Stores in Uganda, which supports last-mile delivery to facilities. An implementing partner purchased initial raw materials necessary for production. The cost of materials for local production was compared to the price of commercial ABHR available in Uganda. Results: Between January and August 2021, 23 staff members were trained, and 380 batches of quality-assured ABHR (17,820 L) were produced and distributed to 278 health facilities. Consumption of ABHR in the first distribution was used to benchmark predicted ABHR consumption per targeted facility in subsequent months. Increased demand for ABHR due to the COVID-19 pandemic and the Ebola virus disease outbreak in central Uganda (September 2022) was addressed through emergency requests on a case-by-case basis. ABHR local production costs $3 per liter for materials, less than half of commercial ABHR ($8 per liter). Conclusions: Early results suggest that this approach is potentially sustainable but requires national advocacy as well. Leveraging existing distribution systems while building local capacity for ABHR production and distribution may improve longevity of such innovations in similar resource-limited settings.

背景:可持续、持续供应的含酒精洗手液(ABHR)对卫生机构的卫生保健工作者至关重要。世卫组织为个别卫生设施的生产提供指导。在乌干达,利用这一指导方针,在地区地方政府一级实施了一种创新办法,生产并随后将ABHR分发给地方设施一级生产能力有限的初级保健保健设施。该项目得到了疾病预防控制中心与传染病研究所合作的支持,并有针对性地让政府或地区与当地伙伴合作,以确保可持续性。方法:地区利益相关者参与,以获得支持,并明确角色和责任。总的来说,在6个受支持的地区,每个地区有4名工作人员被区卫生官员提名接受培训:2名工作人员接受了编制ABHR和进行内部质量控制的培训,2名接受了外部质量控制的培训。各区提供ABHR生产单位设施,并促进将基本用品交付系统纳入乌干达国家医疗商店,该系统支持向设施运送最后一英里物资。执行伙伴购买了生产所需的初始原材料。将当地生产材料的成本与乌干达现有的商业ABHR的价格进行了比较。结果:2021年1月至8月期间,培训了23名工作人员,生产了380批质量有保证的ABHR(17,820升),并向278个卫生机构分发。第一次分配的ABHR消耗用于基准预测每个目标设施在随后几个月的ABHR消耗。由于2019冠状病毒病大流行和乌干达中部埃博拉病毒病爆发(2022年9月),对ABHR的需求增加,已通过逐案紧急请求得到解决。当地生产ABHR的材料成本为每升3美元,不到商业ABHR(每升8美元)的一半。结论:早期结果表明,这种方法可能是可持续的,但也需要国家的倡导。利用现有的分销系统,同时建设ABHR生产和分销的当地能力,可能会在类似的资源有限的环境中延长这种创新的寿命。披露:没有
