抗生素管理
  • 文章类型: Journal Article
    背景:在抗生素耐药性上升的时代,在选择性外科手术中经验性和预防性抗菌治疗的成功方案,重要的是要根据创伤部位来考虑创伤人群的具体需求,严重程度,和环境暴露。在这项研究中,我们旨在比较在初次评估期间接受抗生素治疗的高活化创伤患者与未接受抗生素治疗的患者的结局.
    方法:在一家城市机构对2021年期间作为最高创伤激活标准的抗生素给药患者进行了回顾性图表回顾。患者人口统计,损伤,和结果数据是通过我们机构创伤登记处的手动数据抽象收集的。
    结果:我们研究中近一半的创伤患者在初步评估后接受了抗生素治疗,发现年龄在最初的1.5小时内与抗生素使用显著相关。患有穿透性损伤的年轻男性更有可能接受抗生素治疗。78%接受早期抗生素治疗的患者接受了手术,而没有接受早期抗生素治疗的患者中有61%没有接受早期抗生素治疗(P<0.001)。
    结论:这些发现强调了根据患者的年龄和特定的损伤模式来个体化抗生素治疗的重要性。他们还强调创伤提供者需要优先考虑抗生素管理。
    BACKGROUND: In the era of rising antimicrobial resistance and successful protocols for empiric and prophylactic antimicrobial therapy in elective surgical procedures, it is important to consider the specific needs of the trauma population based on injury location, severity, and environmental exposures. In this study, we aim to compare outcomes of high-activation trauma patients who received antibiotics during initial evaluation with those who did not.
    METHODS: A retrospective chart review of patients focusing on antimicrobial administration who presented as the highest trauma activation criteria during the year 2021 was conducted at a single urban institution. Patient demographic, injury, and outcome data ere collected through manual data abstraction from our institutional trauma registry.
    RESULTS: Nearly half of all trauma patients in our study received antibiotics after initial evaluation and age was found to be significantly associated with antibiotic administration within the first 1.5 h. Young men with penetrating injuries were more likely to receive antibiotic treatment. Seventy-eight percent of patients who received early antibiotics underwent a procedure, while 61% of those who did not receive early antibiotics did not (P < 0.001).
    CONCLUSIONS: These findings emphasize the importance of individualizing antibiotic treatment based on the patient\'s age and specific injury pattern. They also underscore the need for trauma providers to prioritize antibiotic stewardship.

    克林霉素是一种lincosamide抗生素,已被用作局部药物,口服,或注射制剂超过五十年。它表现出狭窄的微生物活性,主要针对革兰氏阳性和厌氧菌。在皮肤科,克林霉素主要用作局部药物,通常用于治疗寻常痤疮。尽管围绕抗生素耐药性和/或其对抗生素治疗功效的相对贡献存在疑问,大量数据支持外用克林霉素对寻常痤疮的治疗价值。作为一个系统性的代理人,克林霉素用于口服治疗各种皮肤细菌感染,有时是寻常痤疮,后者的口服治疗在最近几年不太常见。克林霉素的作用方式得到了显示其抗炎和抗生素机制的数据的支持。这里讨论的是药代动力学特征和构效关系。克林霉素在多种疾病状态下的不同应用,其功效,这里还回顾了安全方面的考虑,包括局部和全身制剂。重点放在皮肤病学的用途上,但也讨论了与临床医生相关的克林霉素的其他信息。
    Clindamycin is a lincosamide antibiotic that has been used as a topical, oral, or injectable formulation for over five decades. It exhibits a narrow spectrum of microbiologic activity, primarily against gram-positive and anaerobic bacteria. In dermatology, clindamycin has been used primarily as a topical agent, usually for the treatment of acne vulgaris. Despite questions surrounding antibiotic resistance and/or its relative contribution to antibiotic treatment efficacy, a large body of data support the therapeutic value of topical clindamycin for acne vulgaris. As a systemic agent, clindamycin is used orally to treat a variety of cutaneous bacterial infections, and sometimes for acne vulgaris, with oral treatment for the latter less common in more recent years. The modes of action of clindamycin are supported by data showing both its anti-inflammatory and antibiotic mechanisms, which are discussed here along with pharmacokinetic profiles and structure-activity relationships. The diverse applications of clindamycin for multiple disease states, its efficacy, and safety considerations are also reviewed here, including for both topical and systemic formulations. Emphasis is placed on uses in dermatology, but other information on clindamycin relevant to clinicians is also discussed.

    这项研究的目的是激发临床医生的观点,以帮助减少无症状菌尿的抗生素处方,并改善以患者为中心的教育手册,以治疗患有尿路感染或无症状菌尿的老年人。
    在2023年10月至2024年4月之间,我们对治疗年龄≥65岁患者尿路感染或尿液中细菌的临床医生进行了半结构化定性访谈,在传染病诊所,社区老年人生活设施,记忆护理诊所,和一般实践。我们基于行为变化框架开发了采访指南,并使用归纳和演绎编码技术对录音采访的书面成绩单进行了主题分析。
    我们从临床医生那里确定了一些关于无症状性菌尿治疗的共同主题。其中包括强调订购和解释尿检,指南和老年人个体患者护理之间的紧张关系,使用流行病学数据来影响处方实践,预先准备好的沟通谈话要点,以及对患者和临床团队的教育材料的兴趣。
    关于需要补充尿检症状的教育,关于过度使用抗生素影响的数据,应采用口头和书面交流策略,以减少无症状菌尿的抗生素处方。
    UNASSIGNED: The aim of this study was to elicit clinicians\' perspectives to help reduce antibiotic prescribing for asymptomatic bacteriuria and improve a patient-centered educational brochure for older adults with urinary tract infections or asymptomatic bacteriuria.
    UNASSIGNED: Between October 2023 and April 2024, we conducted semi-structured qualitative interviews of clinicians who treat patients aged ≥65 years for urinary tract infections or bacteria in the urine, at infectious disease clinics, community senior living facilities, memory care clinics, and general practice. We developed an interview guide based on a behavior change framework and thematically analyzed written transcripts of audio-recorded interviews using inductive and deductive coding techniques.
    UNASSIGNED: We identified several common themes surrounding management of asymptomatic bacteriuria from clinicians. These included an emphasis on ordering and interpreting urine tests, tension between guidelines and individual patient care for older adults, use of epidemiologic data to influence prescribing practices, pre-prepared communication talking points, and interest in educational materials for patients and clinical teams.
    UNASSIGNED: Education about the need for symptoms to supplement urine testing, data about the impact of overuse of antibiotics, and oral and written communication strategies should be addressed to reduce antibiotic prescribing for asymptomatic bacteriuria.

    BACKGROUND: The increase and global dissemination of antibiotic resistance limit the use of antibiotics to prevent and treat infections. Implementing antibiotic stewardship programs guided by local data on prescription profiles is a useful strategy to reduce the burden of antibiotic resistance. The aim was to determine the prevalence of antibiotic use and guideline compliance at Luang Prabang provincial hospital, Lao PDR.
    METHODS: A point prevalence survey of antibiotics was conducted among hospitalized patients admitted to Luang Prabang hospital (204 beds) in Lao PDR on May 25, 2023. All patients presenting at 8:00 AM were eligible. Sociodemographic data, indications for antibiotic use, and antibiotic prescriptions were collected from medical records using a paper-based questionnaire and entered into an electronic platform following WHO methodology. The prevalence of antibiotic use was determined.
    RESULTS: Out of the 102 patients included, 60(58.8%) were undergoing antibiotic treatment, of which 33(55.0%) received combination therapy, and 7(10.5%) had two indications for antibiotic use. The highest prevalence was in the surgical ward (14/15, 93%) followed by general paediatrics (18/27, 67%). Out of the 100 antibiotic prescriptions, 47(47%) were for community-acquired infections, 26(26%) for surgical prophylaxis, 13(13%) for hospital-acquired infections and 5(5%) for medical prophylaxis. Twenty(20%) antibiotics were prescribed for obstetrics and gynaecology prophylaxis, 17(17%) for intra-abdominal infections, and 10(10.0%) for pneumonia treatment as well as bone, and joint infections. The main antibiotics prescribed were ceftriaxone 36(34.6%), metronidazole 18(17.3%), ampicillin 8(7.7%), and gentamicin 8(7.7%). Only 2(3%) samples were sent to the laboratory, one of which showed a positive culture for Escherichia coli Extended Spectrum β-Lactamase. According to the WHO Access Watch and Reserve classification, 55(52.9%) molecules belonged to the Access category, 47(49.1%) to the Watch category, and none to the Reserve category. Only 14.9% of antibiotic prescriptions were fully compliant with current guidelines.
    CONCLUSIONS: This study indicated a significant prevalence of antibiotic use and a very low compliance with guidelines at Luang Prabang provincial hospital, Lao PDR. This highlights an urgent need for comprehensive strategies at all levels to optimize antibiotic use in hospitals, emphasizing diagnostic improvements, and continued research to address the factors driving this excessive antibiotic usage and improve adherence to guidelines.

    目标:在法国,75%的全身性抗生素是由初级保健的全科医生(GP)规定的。我们旨在评估与处方持续时间过长相关的不当使用的负担。
    方法:在2021年,我们对六个GP的网络进行了横断面和药物经济学研究。最佳持续时间的参考是法国国家抗生素处方指南的参考。
    结果:在196种抗生素处方中,33.7%的人持续时间过长,每个处方平均超过0.9[0.86-0.94]至1.6[1.45-1.72]天。耳朵,鼻子,喉咙,呼吸道,与过量处方相关的主要感染是皮肤和皮肤结构感染。药物经济分析显示,2021年法国处方时间过长的成本估计为1.51亿欧元至2.62亿欧元。
    结论:解决全科医生的抗生素处方持续时间过长可能是抗菌药物管理计划中一种强大且节省成本的工具。
    OBJECTIVE: In France, 75% of systemic antibiotics are prescribed by general practitioners (GPs) in primary care. We aimed to estimate the burden of inappropriate use related to excessive prescription duration.
    METHODS: In 2021, we performed a cross-sectional and pharmaco-economic study of a network of six GPs. The references for optimal durations were those of the French national guidelines for antibiotic prescription.
    RESULTS: Out of 196 antibiotic prescriptions, 33.7 % were of excessive duration, with a mean excess of 0.9 [0.86-0.94] to 1.6 [1.45-1.72] days per prescription. Ear, nose, and throat, respiratory tract, and skin and skin structure infections were the main infections associated with excessive prescription. The pharmaco-economic analysis showed that the cost of excessive prescription duration would range from an estimated 151 to 262 million € in France in 2021.
    CONCLUSIONS: Addressing excessive antibiotic prescription duration by GPs may represent a powerful and cost-saving tool in antimicrobial stewardship programs.

    背景:抗生素耐药性对现代医学构成了重大的全球健康威胁。未来接受培训的医生的意识和态度可能在解决这一重要问题方面发挥关键作用,影响耐药性的控制,促进负责任的抗生素管理。这项研究旨在评估知识,态度,关于三级护理教学医院医学实习生抗生素使用和抗菌素耐药性的实践。
    方法:对来自多个医疗机构的123名MBBS实习生进行了基于问卷调查的横断面研究。实习生的知识,态度,记录了自我报告的抗生素使用实践.
    结果:根据123名参与者的调查答复,116人(94.31%)意识到滥用抗生素的不利影响,认识到无效治疗的风险,副作用增加,长期患病,细菌抗性,和更高的医疗费用。大多数(106,86.18%)承认治疗抗生素耐药性感染的挑战,和69(56.10%)正确确定细菌不是普通感冒和流感的原因。大多数(115,93.5%)认为抗生素耐药性是一个重要的全球健康问题。在态度上,90%(73%)的人认为感冒应避免使用抗生素,但是80人(65%)认为他们加速了发烧的恢复。只有48人(39%)认识到抗生素有助于耐药性,而102人(83%)同意跳过剂量会促进耐药性。大多数支持合理使用抗生素的医院政策(118,96%)和课程(112,91%)。关于实践,12名(9.76%)实习生承认过度使用抗生素,68(55.28%)在开始使用抗生素之前咨询了医生,和87(70.73%)检查的到期日。此外,62(50.41%)首选抗生素治疗咳嗽和咽喉痛症状。
    结论:这项研究强调,虽然实习生对滥用抗生素的危害有很好的认识和认识,他们没有将这些知识转化为实践。这表明理解和应用之间的脱节。因此,有必要在医学课程中增加合理的抗生素处方和管理模块,以确保知识有效地转化为不断变化的信念和实践。
    BACKGROUND: Antibiotic resistance presents a significant global health threat to modern medicine. The awareness and attitude of future doctors undergoing training may play a crucial role in addressing this important issue, influencing the control of resistance and promoting responsible antibiotic stewardship. This study aimed to estimate knowledge, attitudes, and practices regarding antibiotic usage and antimicrobial resistance among tertiary care teaching hospital medical interns.
    METHODS: The questionnaire-based cross-sectional study was conducted on 123 MBBS interns from multiple medical institutions. Intern\'s knowledge, attitudes, and self-reported practices regarding antibiotic use were recorded.
    RESULTS: Based on survey responses from 123 participants, 116 (94.31%) were aware of the adverse effects of indiscriminate antibiotic use, recognizing the risks of ineffective treatment, increased adverse effects, prolonged illness, bacterial resistance, and higher medical costs. Most (106, 86.18%) acknowledged the challenges of treating antibiotic-resistant infections, and 69 (56.10%) correctly identified that bacteria are not a cause of the common cold and flu. Most (115, 93.5%) recognized antibiotic resistance as a significant global health problem. In attitude, 90 (73%) believed antibiotics should be avoided for colds, but 80 (65%) thought they hastened fever recovery. Only 48 (39%) recognized that antibiotics contribute to resistance, while 102 (83%) agreed skipping doses fosters resistance. Most support hospital policies (118, 96%) and curriculum courses (112, 91%) for rational antibiotic use. Regarding practice, 12 (9.76%) interns admitted to overusing antibiotics, 68 (55.28%) consulted a doctor before starting antibiotics, and 87 (70.73%) checked expiry dates. Additionally, 62 (50.41%) preferred antibiotics for cough and sore throat symptoms.
    CONCLUSIONS: The study highlights that while interns have a good knowledge and awareness of the harms of antibiotic misuse, they are not translating this knowledge into practice. This indicates a disconnect between understanding and application. Therefore, there is a need to add a rational antibiotic prescription and stewardship module to the medical curriculum to ensure that knowledge is effectively translated into changing beliefs and practices.

    抗生素管理计划(ASP)是世卫组织提出的一个新概念,但是护士还没有准备好接受这个计划。护士的培训和授权是提高他们对ASP的知识和参与度的最佳策略。这项混合方法研究用于评估护士参与ASP的感知角色和障碍。对420名临床护士进行了在线调查,以确定他们的角色,在护士和感染控制从业人员中进行了23次个人访谈,以探索障碍并提出克服已确定障碍的建议.大多数护士同意ASP中确定的16个角色,其中“抗生素给药和降级”(82.61%),\'IV到PO的抗生素转换,门诊抗生素治疗(85.23%),和门诊管理,长期护理,再次入院的患者(81.19%)与参与者的一致性最低。通过定性访谈产生的主要主题是缺乏关于ASP的知识,多学科团队之间沟通不畅,缺乏机会和多学科参与,缺乏关于ASP的正规教育和培训,缺乏ASP能力和在政策中定义的角色,角色冲突或权力/职位,资源的可用性,缺乏时间保护。护士在成功实施抗生素管理计划中起着不可或缺的作用。护士的授权将帮助他们采用ASP中的独特角色。通过应对这些挑战,护士可以为抗生素管理工作做出重大贡献,并改善患者的治疗效果。
    The antibiotic stewardship programme (ASP) is a new concept initiated by WHO, but nurses are not yet ready to adopt the program. The training and empowerment of nurses are the best strategies for enhancing their knowledge and engagement in ASP. This mixed-method study was used to assess perceived roles and barriers of nurses\' involvement in ASP. An online survey was conducted among 420 clinical nurses to identify their role, and 23 individual interviews were performed among nurses and infection control practitioners to explore the barriers and recommendations to overcome the identified barriers. The majority of the nurses agreed with the sixteen identified roles in ASP, of which \'antibiotic dosing and de-escalation\' (82.61%), \'IV to PO conversion of antibiotic, outpatient antibiotic therapy\' (85.23%), and \'outpatient management, long-term care, readmission\' of the patients (81.19%) had the lowest agreement from the participants. The major themes generated through the qualitative interviews were a lack of knowledge about ASP, poor communication between multidisciplinary teams, lack of opportunity and multidisciplinary engagement, lack of formal education and training about ASP, lack of ASP competency and defined roles in policy, role conflict or power/position, availability of resources, and lack of protected time. Nurses play an integral role in the successful implementation of antibiotic stewardship programs. The empowerment of nurses will help them to adopt the unique role in ASP. Nurses can significantly contribute to antibiotic stewardship efforts and improve patient outcomes through addressing these challenges.

    微生物群体失调已成为影响造血干细胞移植(HSCT)结果的关键因素。这篇全面的综述深入探讨了微生物组组成与HSCT结果之间的复杂关系,强调菌群失调影响植入的机制,移植物抗宿主病(GVHD),感染率,和总体生存率。肠道微生物组在调节免疫反应和维持肠道稳态方面发挥着关键作用。这两者对于HSCT的成功至关重要。这篇综述旨在阐明潜在的途径和潜在的治疗策略,以减轻HSCT患者与微生物组失衡相关的不良结局。整合微生物组调节策略,如益生菌,益生元,粪便微生物移植(FMT),将抗生素纳入临床实践可以显著改善移植后患者的预后和生活质量。
    Microbiome dysbiosis has emerged as a critical factor influencing the outcomes of hematopoietic stem cell transplantation (HSCT). This comprehensive review delves into the intricate relationship between microbiome composition and HSCT outcomes, highlighting the mechanisms through which dysbiosis impacts engraftment, graft-versus-host disease (GVHD), infection rates, and overall survival. The gut microbiome plays a pivotal role in modulating immune responses and maintaining intestinal homeostasis, both of which are crucial for the success of HSCT. This review aims to elucidate the underlying pathways and potential therapeutic strategies to mitigate adverse outcomes associated with microbiome imbalances in HSCT patients. Integrating microbiome modulation strategies such as probiotics, prebiotics, fecal microbiota transplantation (FMT), and antibiotic stewardship into clinical practice can significantly improve patient outcomes and quality of life post-transplantation.

    背景:随着多重耐药感染的出现,医疗保健专业人员必须评估经验性抗生素治疗的有效性。
    目的:评估引起肝硬化患者自发性感染的微生物对抗生素的敏感性,并根据主要临床指南评估经验性抗生素治疗的适用性。
    方法:这项横断面研究利用了来自阿根廷和乌拉圭的肝硬化和培养阳性自发性细菌感染患者的前瞻性研究的两个数据集。我们评估了对常用抗生素的敏感性,并根据欧洲和美国的建议评估了覆盖率。
    结果:我们分析了229例患者中238例培养阳性自发性感染。在实施经验性治疗社区获得性自发性感染的建议时,头孢他啶将导致39%的覆盖率,而头孢曲松将达到70%。头孢吡肟,这不包括在建议中,将提供74%的覆盖率。使用厄他培南治疗医院感染只会覆盖这些发作的56%,而美罗培南或亚胺培南覆盖率达到73%。只有美罗培南或亚胺培南加万古霉素的组合在医疗保健相关或医院自发性细菌感染中的覆盖率超过85%。
    结论:我们的研究发现,在坚持建议的情况下,在特定的临床情景中没有足够的覆盖。强调基于当地流行病学数据的指南的必要性。
    BACKGROUND: With the emergence of multidrug-resistant infections, healthcare professionals must evaluate the effectiveness of empiric antibiotic treatments.
    OBJECTIVE: To assess the antibiotic susceptibility patterns of microorganisms causing spontaneous infections in patients with cirrhosis and to evaluate the suitability of empiric antibiotic treatments based on major clinical guidelines.
    METHODS: This cross-sectional study utilized two datasets from prospective studies of patients with cirrhosis and culture-positive spontaneous bacterial infections in Argentina and Uruguay. We estimated susceptibility to commonly used antibiotics and assessed coverage following European and American recommendations.
    RESULTS: We analyzed 238 episodes of culture-positive spontaneous infections in 229 patients. When implementing the recommendations for empiric treatment of community-acquired spontaneous infections, ceftazidime would result in 39 % coverage, whereas ceftriaxone would reach 70 %. Cefepime, which is not included in the recommendations, would have provided coverage of 74 %. Using ertapenem for nosocomial infections would have only covered 56 % of these episodes, whereas meropenem or imipenem reached 73 % coverage. Only the combination of meropenem or imipenem plus vancomycin would achieve a coverage surpassing 85 % in healthcare-associated or nosocomial spontaneous bacterial infections.
    CONCLUSIONS: Our study uncovers inadequate coverage in specific clinical scenarios when adhering to recommendations, underscoring the necessity of guidelines based on local epidemiological data.
