    背景:基于酒精的手擦(ABHR)是手部卫生(HH)的黄金标准,并且是感染预防和控制(IPC)策略的基石。然而,几个因素影响卫生工作者对ABHR的有效使用。这项研究评估了卫生工作者对本地生产的ABHR产品和HH行为的耐受性和可接受性。
    方法:根据WHO的标准化方案进行了一项基于医院的纵向干预研究,以评估ABHR的耐受性和可接受性(方法1)。塞拉利昂4家医院的60名卫生工作者在30天的时间内接受了训练有素的观察员的三次单独访问(第1天、第3-5天和第30天)的观察。感兴趣的结果包括使用主观和客观测量评估的皮肤耐受性和产品可接受性。
    结果:客观和主观评价显示出较强的皮肤耐受性和产品的高可接受性。在所有三次访问中,经过培训的观察者评估的皮肤耐受性评分<2,≥97%的参与者,超过WHO基准评分(BMS=<2in≥75%)。参与者对整体皮肤完整性的自我评估为97%(第2次访问)和98%(第3次访问),得分>4(BMS=>4,≥75%)。主要可接受性标准在第3次就诊时增加到95%(颜色)和88%(气味)(BMS=>4,≥50%)。尽管可接受性很高,在第2次和第3次访问期间,产品的干燥效果分别为52%和58%(BMS=>4in≥75%)。有积极的HH行为(n=53,88%),其中一半以上(n=38,63%)几乎在每个HH时刻都表现出HH。平均ABHR明显较高(76.1ml,标准差±35),特别是在护士(平均=80.1毫升)和医生(平均=74.0毫升)。
    结论:世界卫生组织制定的,本地生产的ABHR耐受性良好,并被卫生工作者接受.这些发现支持持续利用基于证据的,在资源有限的环境中进行具有成本效益的手卫生干预。高手擦消耗和频繁的HH实践是明显的HH行为。建议进一步研究以优化皮肤干燥的产品配方,并研究ABHR消耗与手部卫生依从性之间的关联。
    BACKGROUND: Alcohol-based handrub (ABHR) is the gold standard for hand hygiene (HH) and is a cornerstone of infection prevention and control (IPC) strategies. However, several factors influence the efficient use of ABHR by health workers. This study evaluated the tolerability and acceptability of a locally produced ABHR product and HH behaviour among health workers.
    METHODS: A longitudinal hospital-based intervention study was conducted in accordance with the WHO\'s standardized protocol for evaluating ABHR tolerability and acceptability (Method 1). Sixty health workers across 4 hospitals in Sierra Leone were observed over a 30-day period at three separate visits (days 1, 3-5, and 30) by trained observers. The outcomes of interest included skin tolerability and product acceptabilityevaluated using subjective and objective measures.
    RESULTS: Objective and subjective evaluations demonstrated strong skin tolerability and high acceptability with the product. At all three visits, the skin tolerability score assessed by trained observers was < 2 in ≥ 97% of participants, exceeding the WHO benchmark score (BMS = < 2 in ≥ 75%). Participants\' self-evaluations of overall skin integrity were 97% (visit 2) and 98% (visit 3) for scores > 4 (BMS = > 4 in ≥ 75%). The primary acceptability criteria increased up to 95% (colour) and 88% (smell) at visit 3 (BMS = > 4 in ≥ 50%). Despite high acceptability, the product\'s drying effect remained low at 52% and 58% during visits 2 and 3, respectively (BMS = > 4 in ≥ 75%). There were positive HH behaviours (n = 53, 88%), with more than half (n = 38, 63%) of them exhibiting HH at almost every HH moment. The mean ABHR was notably high (76.1 ml, SD ± 35), especially among nurses (mean = 80.1 ml) and doctors (mean = 74.0 ml).
    CONCLUSIONS: The WHO-formulated, locally produced ABHR was well tolerated and accepted by health workers. These findings support the continuous utilization of evidence-based, cost-effective hand hygiene interventions in resource-limited settings. High handrub consumption and frequent HH practices were noticeable HH behaviours. Further research is recommended to optimize product formulations for skin dryness and investigate the association between ABHR consumption and hand hygiene compliance.

    背景:对SARS-CoV-2在撒哈拉以南非洲国家的传播调查不充分,尤其是在大流行的后期阶段。我们的目标是在2022年11月/12月评估塞拉利昂的Omicron后情况,考虑到SARS-CoV-2血清状态,疫苗接种,和行为因素。
    方法:在弗里敦的一家妇产医院进行的一项横断面研究中,塞拉利昂,患者和工作人员均提供干血斑样本,使用抗SARS-CoV-2-ELISA分析抗S和抗NIgG的流行情况.此外,我们通过问卷调查收集社会人口统计学和感染相关信息.结果参数包括血清阳性,感染相关血清阳性率,和自我报告的疫苗接种状况。我们使用逻辑回归来确定与先前感染和疫苗接种状态的关联。
    结果:在791名参与者中(389名患者,402名工作人员),670例(84.7%)显示由感染或疫苗接种引起的SARS-CoV-2血清状态阳性。在514名参与者的子样本中,可以确定先前的自然感染,441例(85.8%)受影响。先前的感染与女性和高等教育水平有关。总的来说,60.3%报告已接种疫苗。工作人员与病人相反,社会经济地位较高的个体更有可能报告疫苗接种.与中等风险相比,评估其COVID-19风险较高或较低的个体更有可能感染病毒,而接受疫苗接种的可能性较小。
    结论:我们的发现表明,自2022年的Omicron浪潮以来,塞拉利昂人口几乎普遍暴露于SARS-CoV-2。尽管鉴于该国相对较低的超额死亡率,这是令人鼓舞的,未来关于高病毒暴露对流行病抵御能力和公共卫生影响的长期影响的调查将至关重要.
    BACKGROUND: Spread of SARS-CoV-2 in Sub-Saharan African countries has been poorly investigated, especially in the later pandemic stages. We aimed to assess the post-Omicron situation in Sierra Leone in November/December 2022 considering SARS-CoV-2 serostatus, vaccinations, and behavioral factors.
    METHODS: In a cross-sectional study conducted in a maternity hospital in Freetown, Sierra Leone, both patients and staff provided dried blood spot samples for analysis of anti-S and anti-N IgG prevalence using Anti-SARS-CoV-2-ELISA. Additionally, we collected sociodemographic and infection-related information through questionnaires. Outcome parameters included seropositivity, infection-related seroprevalence, and self-reported vaccination status. We used logistic regression to identify associations with prior infection and with vaccination status.
    RESULTS: Out of 791 participants (389 patients, 402 staff), 670 (84.7 %) displayed a positive SARS-CoV-2 serostatus resulting from either infection or vaccination. Among a sub-sample of 514 participants within which determination of prior natural infection was possible, 441individuals (85.8 %) were affected. Prior infection was associated with female sex and tertiary education level. Overall, 60.3 % reported having been vaccinated. Staff as opposed to patients, and individuals with higher socioeconomic status were more likely to report vaccination. Individuals who assessed their risk of COVID-19 as either higher or lower compared to a medium-level risk were more likely to have contracted the virus and less likely to have received vaccination.
    CONCLUSIONS: Our findings suggest that since the Omicron wave in 2022, the Sierra Leonean population has almost universally been exposed to SARS-CoV-2. While this is encouraging in the light of relatively low excess mortality in the country, future investigations on the long-term effect of high viral exposure on epidemic resilience and public health impact will be crucial.

    COVID-19大流行引发的全球健康危机强调了迅速开发和分发疫苗以遏制病毒传播的必要性。然而,关于疫苗接受和犹豫的讨论主要集中在疫苗接种前的态度上,通常忽略疫苗接种后经验在塑造个人和社区对疫苗的态度方面的重要性。这种监督在低收入和中等收入国家(LMICs)的医护人员中尤为重要。他们在抗击大流行和影响公众疫苗情绪方面发挥着双重作用。利用计划行为理论,这项研究探讨了塞拉利昂医护人员的疫苗接种后经历,并评估了这些经历如何影响他们对疫苗安全的态度,功效和他们倡导在社区内接种疫苗。采用定性设计,这项研究采访了24名医护人员,其中21人接种了COVID-19疫苗。半结构化面试,用英语或Krio进行,录音,逐字转录,并使用主题分析进行分析,以确定关键主题。确定了三个主题:积极的疫苗接种经验超出了最初的预期,坚信疫苗的保护性益处和在疫苗宣传中的积极作用。尽管最初由于担心潜在的不利影响而犹豫不决,参与者报告疫苗接种后没有重大问题,培养对疫苗安全性和有效性的信任。医护人员接种疫苗后的积极经历大大加强了他们的疫苗宣传,影响他们对病人的建议,朋友,家庭,同事和社区成员。这项研究强调了理解和利用医护人员经验来提高公众信任和疫苗使用率的重要性。对于低收入国家的大流行应对工作至关重要。
    The global health crisis precipitated by the COVID-19 pandemic underscored the necessity of swift vaccine development and distribution to curb virus transmission. However, discussions on vaccine acceptance and hesitancy have predominantly focused on pre-vaccination attitudes, often overlooking the significance of post-vaccination experiences in shaping individual and communal attitudes toward vaccines. This oversight is particularly critical among healthcare workers in low- and middle-income countries (LMICs), who play a dual role in combating the pandemic and influencing public vaccine sentiment. Using the theory of planned behavior, this study explores the post-vaccination experiences of healthcare workers in Sierra Leone and assesses how these experiences influence their attitudes toward vaccine safety, efficacy and their advocacy for vaccine uptake within their communities. Employing a qualitative design, the study interviewed 24 healthcare workers, 21 of whom were vaccinated against COVID-19. Semi-structured interviews, conducted in English or Krio, were audio recorded, transcribed verbatim and analyzed using thematic analysis to identify key themes. Three themes were identified: positive vaccination experiences exceeding initial expectations, strong belief in the vaccine\'s protective benefits and active roles in vaccine advocacy. Despite initial hesitations due to concerns over potential adverse effects, participants reported no significant issues post-vaccination, fostering trust in vaccine safety and effectiveness. Healthcare workers\' positive post-vaccination experiences significantly bolster their vaccine advocacy, influencing their recommendations to patients, friends, families, colleagues and community members. This study highlights the importance of understanding and leveraging healthcare workers\' experiences to enhance public trust and vaccine uptake, crucial for pandemic response efforts in LMICs.

    背景:获得所需功效的医疗产品,质量和安全对每个人的健康和福祉至关重要。为了实现这一里程碑,每个国家都需要一个强大而强大的国家监管机构(NRA),该机构是独立的,以结果为导向。在世界卫生组织(WHO)的帮助下,全球基准测试工具是用于评估NRA监管能力的黄金标准。
    目的:本研究评估了塞拉利昂国家药品管理局履行监管职能的能力。
    方法:这项描述性横断面研究使用了定性和定量方法。定量方法使用自我管理问卷,定性方面包括案头审查,审查关键的监管文件,如法律,法规,政策,指导方针,标准操作程序和报告。使用的数据收集工具是世卫组织全球基准工具(GBT),用于“评估国家医疗产品法规体系VI”。
    结果:大多数参与者拥有研究生学位(60%),72%的人在全国步枪协会有超过10年的工作经验。在评估的251个次级指标中,85项(34%)分指标得到全面实施。在评估的八(8)项职能中,与临床试验监督和警惕性相关的子指标执行得最多,67%和62%,分别。在评估的9个指标中,79%的与质量和风险管理相关的子指标得到了实施。这项研究的结果表明,PBSL在成熟度级别1运行。尽管达到了其他指标,但缺乏赋予PBSL履行其监管职能的法律和法规是一项重大挑战。该研究报告了有效运作的其他挑战,包括但不限于缺乏足够的工作人员,药品销售执法不力和质量控制实验室设备差。
    BACKGROUND: Access to medical products of the required efficacy, quality and safety is essential for everyone\'s health and wellbeing. To achieve this milestone, every country needs a robust and strong performing National Regulatory Authority (NRA) that is independent and outcome oriented. With the help of the World Health Organization (WHO), the global benchmarking tool is the gold standard used to assess the regulatory capacity of NRAs.
    OBJECTIVE: This study assessed the capacity of the National Medicines Regulatory Authority in Sierra Leone to perform its regulatory functions.
    METHODS: This descriptive cross-sectional study used both qualitative and quantitative approaches. A self-administered questionnaire was used for the quantitative approach, and the qualitative aspect consisted of a desk review looking at key regulatory documents such as laws, regulations, policies, guidelines, standard operating procedures and reports. The data collection tool used was the WHO global benchmarking tool (GBT) for \"Evaluation of National Regulatory System of Medical Product Version VI.
    RESULTS: The majority of the participants had a postgraduate degree (60%), and 72% had over 10 years of experience working at the NRA. Out of 251 sub-indicators assessed, 85 (34%) sub-indicators were fully implemented. Of the eight (8) functions assessed, sub-indicators related to clinical trial oversight and vigilance were the most implemented, with 67% and 62%, respectively. Of the 9 indicators assessed, 79% of the sub-indicators that are related to quality and risk management were implemented. The results of this study showed that PBSL operates at maturity level 1. The absence of laws and regulations that give PBSL the mandate to perform its regulatory functions was a major challenge even though other indicators were met. The study reported other challenges toward effective functioning, including but not limited to a lack of sufficient staff, weak enforcement of the sale of medicines and a poorly equipped quality control laboratory.

    乳腺癌是全球女性中最常见的恶性肿瘤和癌症死亡的重要原因。该疾病占新癌症病例的25%(167万),是癌症死亡的第五大原因。塞拉利昂所有类型癌症的发病率约为25%。然而,没有证据证明该国女性患乳腺癌的危险因素.这项研究的主要目的是评估塞拉利昂弗里敦筛查乳腺癌的女性中与乳腺癌相关的危险因素。
    我们进行了一项乳腺癌病例对照研究,涉及116例确诊乳腺癌病例和116例对照。问卷旨在收集社会人口统计数据,生殖和行为危险因素。使用逻辑回归进行分析以评估乳腺癌与危险因素之间的关联。
    在最终的多元逻辑回归中,有正规的教育水平,(aOR0.1,0.03-0.26,p=0.001)每周进行30分钟以上的体育锻炼(aOR0.5(0.9-0.7,p=0.001)。吸烟(aOR4.8,1.2-18.5,p=0.023)和乳腺癌家族史(aOR9.9吸烟(OR4.4,1.2-18.5,p=0.023)和乳腺癌家族史(OR9.9,2.7-36.45,p=0.040)被确定为乳腺癌的主要危险因素。这项研究没有发现生殖风险因素与乳腺癌之间有任何统计学意义的关联。
    塞拉利昂妇女患乳腺癌的危险因素包括教育程度,身体活动,吸烟和乳腺癌家族史。我们建议对40岁以上且有乳腺癌病史的女性进行筛查。此外,建立乳腺癌登记处.
    UNASSIGNED: breast cancer is the most commonly diagnosed malignancy and an important cause of cancer death among females worldwide. The disease accounted for 25% (1.67 million) of new cancer cases and the fifth cause of cancer deaths. Incidence of all types of cancers is approximately 25% in Sierra Leone. However, there was no documented evidence on risk factors for breast cancer among women in the country. The main aim of this study was to assess risk factors associated with breast cancer among women screened for breast cancer in Freetown Sierra Leone.
    UNASSIGNED: we conducted a case-control study on breast cancer involving 116 confirmed breast cancer cases and 116 controls. Questionnaire was designed to collect data on socio-demographic, reproductive and behavioral risk factors. Analysis was carried using logistic regression to assess the associations between breast cancer and the risk factors.
    UNASSIGNED: in the final multiple logistic regression, had formal educational level, (aOR 0.1, 0.03-0.26, p= 0.001) physical activity for more than 30 minutes per week (aOR 0.5 (0.9- 0.7, p=0.001). Cigarette smoking (aOR 4.8, 1.2-18.5, p=0.023) and family history of breast cancer (aOR 9.9 cigarette smoking (OR 4.4, 1.2-18.5, p=0.023) and family history of breast cancer (OR 9.9, 2.7-36.45, p=0.040) were identified as the main risk factors for breast cancer. This study did not find any statistically significant associations between reproductive risk factors and breast cancer.
    UNASSIGNED: risk factors for breast cancer among women in Sierra Leone include educational level, physical activity, cigarette smoking and family history of breast cancer. We recommended screening program for women above 40 years and had history of breast cancer. Also, to establish breast cancer registry.

    尽管自我药物治疗有潜在的胎儿和产妇风险,在我们的环境中,对自我药疗实践和怀孕期间使用的药物安全性的研究很少。这项研究确定了孕妇使用的药物的自我药疗实践和安全性。
    这项横断面研究是在塞拉利昂三家医院对345名孕妇进行的面对面访谈中进行的。使用描述性统计和二元逻辑回归分析数据,以确定自我药疗的患病率和相关因素。
    共有345名孕妇参加了这项研究。使用常规和/或草药的孕妇的自我药疗患病率为132(38.3%)。此外,93(75%)的常规药物(CM)被归类为可能安全的,其中扑热息痛36(29.0%)是常用的,其次是阿莫西林23(18.5%)和抗疟药22(17.7%),常见疾病如头痛30(25.4%),尿路感染23例(19.4%)和疟疾22例(18.6%)。自我药物治疗的最常见原因是以前的疾病24(27.3%)。丝瓜19(30.2%)是最常用的草药(HM),水肿30(47.6%)是报告最多的疾病。在HM用户中,34(54.0%)认为他们比CM更有效。中学教育(AOR=2.128,95CI=1.191-3.804,p=0.011),高等教育(AOR=2.915,95CI=1.104-7.693,p=0.031),月收入大于NLe1,000(AOR=4.084,95%CI=1.269-13.144,p=0.018),和感知的母亲疾病(AOR=0.367,CI=0.213-0.632,p=<0.001)是自我药物治疗的预测因素。
    自我药疗非常普遍,并且与教育状况有关,月收入,和怀孕期间感知到的产妇疾病。因此,应设计和实施干预计划,以最大程度地减少孕妇自我药物治疗的做法和风险。
    UNASSIGNED: Despite the potential foetal and maternal risks of self-medication, studies on self-medication practice and the safety profile of medicines used during pregnancy are scarce in our setting. This study determined the self-medication practice and safety profile of medicines used among pregnant women.
    UNASSIGNED: This cross-sectional study was conducted in face-to-face interviews among 345 pregnant women at three hospitals in Sierra Leone. Data were analysed using descriptive statistics and binary logistic regression to determine the prevalence and associated factors of self-medication.
    UNASSIGNED: A total of 345 pregnant women participated in the study. The prevalence of self-medication prevalence among pregnant women with conventional and/or herbal medicine was 132 (38.3%). Also, 93 (75%) of the conventional medicines (CMs) were categorised as probably safe, of which paracetamol 36 (29.0%) was commonly used, followed by amoxicillin 23 (18.5%) and antimalarials 22 (17.7%) for common illnesses such as headache 30 (25.4%), urinary tract infection 23 (19.4%) and malaria 22 (18.6%). The most common reason for self-medication was previous experience with the disease 24 (27.3%). Luffa acutangula 19 (30.2%) was the most used herbal medicine (HM), and Oedema 30 (47.6%) was the most reported ailment. Among the HM users, 34 (54.0%) believe they are more effective than CMs. Secondary school education (AOR = 2.128, 95%CI = 1.191-3.804, p = 0.011), tertiary education (AOR = 2.915, 95%CI = 1.104-7.693, p = 0.031), monthly income of greater than NLe 1,000 (AOR = 4.084, 95% CI = 1.269-13.144, p = 0.018), and perceived maternal illness (AOR = 0.367, CI = 0.213-0.632, p = <0.001) were predictors of self-medication.
    UNASSIGNED: Self-medication practice was highly prevalent and was associated with educational status, monthly income, and perceived maternal illness during pregnancy. Therefore, intervention programmes should be designed and implemented to minimise the practice and risk associated with self-medication among pregnant women.

    目的:本研究旨在确定塞拉利昂少女COVID-19健康信息的主要来源,并评估其感知的可信度和对其行为的影响。
    方法:使用基于社会认知理论的便利抽样策略,这项研究探索了青少年对健康信息来源的导航和评估,他们对COVID-19的理解,以及社会和观察性影响对他们健康信念和行为的影响。数据分析涉及使用NVivoV.12软件进行主题分析,关注与观察学习相关的反应中的模式,可信来源和行为结果。
    方法:塞拉利昂,2020年7月。
    方法:在塞拉利昂15-19岁的86名青少年(每组6-8人)中进行了16次焦点小组讨论。
    方法:COVID-19信息的主要来源。
    结果:青春期女孩确定了各种各样的健康信息来源,包括学校,社交媒体,卫生工作者和无线电,基于地理和社会背景,信任和偏好存在显著差异。一个值得注意的发现是对卫生工作者的巨大信任,与5年前埃博拉紧急情况期间的恐惧和不信任形成鲜明对比。这种对卫生专业人员的重新信任成为影响青少年健康行为和接受COVID-19预防措施的关键因素。
    结论:这项研究强调了在COVID-19大流行期间在青春期女孩中导航健康信息的复杂性。它强调了针对当地文化背景的量身定制的公共卫生信息的重要性,解决误解,并建立在可信赖的信息源上,以培养有效的健康行为。未来的干预措施可以优先考虑加强教育资源,利用值得信赖的社区人物,并确保健康传播具有科学准确性和文化敏感性。
    OBJECTIVE: This study aimed to identify the primary sources of COVID-19 health information for adolescent girls in Sierra Leone and evaluate their perceived trustworthiness and influence on their behaviour.
    METHODS: Using a convenience sampling strategy grounded in the social cognitive theory, the study explored adolescents\' navigation and appraisal of health information sources, their understanding of COVID-19, and the impact of societal and observational influences on their health beliefs and actions. Data analysis involved thematic analysis using NVivo V.12 software, focusing on patterns within responses related to observational learning, trusted sources and behavioural outcomes.
    METHODS: Sierra Leone, July 2020.
    METHODS: 16 focus group discussions were conducted among 86 adolescents (6-8 per group) aged 15-19 years in Sierra Leone.
    METHODS: Primary sources of COVID-19 information.
    RESULTS: Adolescent girls identified a diverse range of health information sources, including schools, social media, health workers and radio, with notable differences in trust and preference based on geographical and social contexts. A noteworthy finding was the significant trust placed in health workers, marking a stark contrast to fear and mistrust during the Ebola emergency only 5 years previously. This renewed trust in health professionals emerged as a critical factor influencing adolescents\' health behaviours and acceptance of COVID-19 preventive measures.
    CONCLUSIONS: This study underscores the complexity of navigating health information among adolescent girls during the COVID-19 pandemic. It highlights the importance of tailored public health messaging that accounts for local cultural contexts, addresses misconceptions and builds on trusted information sources to foster effective health behaviours. Future interventions could prioritise enhancing educational resources, leveraging trusted community figures, and ensuring that health communication is scientifically accurate and culturally sensitive.

    背景:抗菌素耐药性(AMR)是全球公共卫生问题,医院不合理使用抗生素是AMR的关键驱动因素。尽管这不是可以预防的,抗菌药物管理(AMS)计划将减少或减缓它。塞拉利昂的研究证据表明,医院大量使用抗生素,但没有研究专门评估儿童的医院AMS计划和抗生素使用情况.我们进行了首次研究,以评估塞拉利昂两家三级医院的AMS计划和抗生素使用情况。
    方法:这是一项基于医院的横断面调查,使用世界卫生组织(WHO)点患病率调查(PPS)方法。使用WHOPPS医院问卷从Ola儿童医院(ODCH)和Makeni地区医院(MRH)的合格患者的医疗记录中收集数据;以及所需的数据收集表格。处方抗生素根据世卫组织的准入标准进行分类,观看,和储备(AWARE)分类。塞拉利昂伦理和科学审查委员会获得了伦理批准。使用SPSS版本22进行统计分析。
    结果:ODCH和MRH均不具备所需的AMS基础设施、政策和实践以及确保合理抗生素处方的监测和反馈机制。在调查的150名患者中,116人(77.3%)在ODCH入院,34人(22.7%)在MRH入院,男性77(51.3%),女性73(48.7%)。平均年龄为2岁(SD=3.5)。抗生素使用的总体患病率为84.7%(95%CI:77.9%-90.0%),年龄在1岁以下的儿童中有77(83.8%)接受了抗生素。接受抗生素治疗的男性比例高于女性。大多数(58,47.2%)的患者接受了至少两种抗生素。处方前五名的抗生素是庆大霉素(100,27.4%),头孢曲松(76,20.3%),氨苄青霉素(71,19.5%),甲硝唑(44,12.1%),和头孢噻肟(31,8.5%)。社区获得性感染是抗生素处方的主要诊断。
    结论:AMS计划的不存在可能导致ODCH和MRH抗生素的大量使用。这有可能增加抗生素选择压力,进而增加该国的AMR负担。有必要建立医院AMS团队,并对卫生工作者进行合理使用抗生素的培训。
    BACKGROUND: Antimicrobial resistance (AMR) is a global public health concern and irrational use of antibiotics in hospitals is a key driver of AMR. Even though it is not preventable, antimicrobial stewardship (AMS) programmes will reduce or slow it down. Research evidence from Sierra Leone has demonstrated the high use of antibiotics in hospitals, but no study has assessed hospital AMS programmes and antibiotic use specifically among children. We conducted the first-ever study to assess the AMS programmes and antibiotics use in two tertiary hospitals in Sierra Leone.
    METHODS: This was a hospital-based cross-sectional survey using the World Health Organization (WHO) point prevalence survey (PPS) methodology. Data was collected from the medical records of eligible patients at the Ola During Children\'s Hospital (ODCH) and Makeni Regional Hospital (MRH) using the WHO PPS hospital questionnaire; and required data collection forms. The prescribed antibiotics were classified according to the WHO Access, Watch, and Reserve (AWaRe) classification. Ethics approval was obtained from the Sierra Leone Ethics and Scientific Review Committee. Statistical analysis was conducted using the SPSS version 22.
    RESULTS: Both ODCH and MRH did not have the required AMS infrastructure; policy and practice; and monitoring and feedback mechanisms to ensure rational antibiotic prescribing. Of the 150 patients included in the survey, 116 (77.3%) were admitted at ODCH and 34 (22.7%) to MRH, 77 (51.3%) were males and 73 (48.7%) were females. The mean age was 2 years (SD=3.5). The overall prevalence of antibiotic use was 84.7% (95% CI: 77.9% - 90.0%) and 77 (83.8%) of the children aged less than one year received an antibiotic. The proportion of males that received antibiotics was higher than that of females. Most (58, 47.2 %) of the patients received at least two antibiotics. The top five antibiotics prescribed were gentamycin (100, 27.4%), ceftriaxone (76, 20.3%), ampicillin (71, 19.5%), metronidazole (44, 12.1%), and cefotaxime (31, 8.5%). Community-acquired infections were the primary diagnoses for antibiotic prescription.
    CONCLUSIONS: The non-existence of AMS programmes might have contributed to the high use of antibiotics at ODCH and MRH. This has the potential to increase antibiotic selection pressure and in turn the AMR burden in the country. There is need to establish hospital AMS teams and train health workers on the rational use of antibiotics.

    每年,塞拉利昂估计有301人死于狂犬病。犬疫苗接种对于狂犬病的预防和控制工作至关重要。然而,疫苗接种率存在相当大的差异。这种变化的原因尚不清楚。我们对2,558个拥有狗的家庭(HHs)进行了横断面研究,以提供影响犬科疫苗接种的因素的见解,以便有针对性地预防和控制到2030年消除。首先,我们描述了养狗的做法,然后建立了一个概率模型来了解与狗接种疫苗相关的因素,最后使用空间扫描统计来识别疫苗接种率低的空间集群。我们的结果表明,只有14%(358/2,558)的参与HH完全接种了狂犬病疫苗。将公务员与私营工人/工匠进行比较时,狗疫苗接种的可能性增加,赔率比(OR)为1.14(95%可信区间(Crl)为0.82-1.56),居住在有兽医机构的地方无(OR=6.43,95%Crl(4.97-8.35),为狗提供护理vs.允许狗自由漫游(OR=2.38,95%Crl(1.80-3.17),并且拥有一只狗与多只狗(OR=1.20,95Crl(0.92-1.56)。相反,当比较位于农村的狗主人与城市地区(OR=0.58,CrI95%(0.43-0.78)。潜在的理解,衡量对狂犬病病毒的全面了解,我们使用参与者的教育水平和对狂犬病流行病学问题的回答来估计,也是疫苗接种概率的重要预测因子(OR=1.44,95%Crl(1.04,2.07)。空间分析确定了Mayamba城市低疫苗接种的高风险集群,半径40公里,相对风险(RR)为1.10,Bo,半径为19.9公里,RR为1.11。这些数据并不支持塞拉利昂实现2030年消除由狗引起的人类狂犬病的目标。我们的研究强调了公众宣传和教育的迫切需要,提高疫苗接种率,增加兽医服务的可及性,和有针对性的干预措施,以支持狂犬病预防和控制工作。
    Annually, Sierra Leone records an estimated 301 human fatalities due to rabies. Canine vaccination is crucial for rabies prevention and control efforts. However, considerable variability exists in vaccination rates. Reasons for this variation remain unclear. We conducted a cross-sectional study across 2,558 dog-owning households (HHs) to provide insights into factors influencing canine vaccination for targeted prevention and control towards elimination by 2030. First, we described dog ownership practices, then built a probabilistic model to understand factors associated with dog vaccination, and finally used a spatial scan statistic to identify spatial clusters where vaccination rates were low. Our results indicated that only 14% (358/2,558) of participating HHs had fully vaccinated their dogs against rabies. The probability of dog vaccination increased when comparing civil servants to private workers/artisans, with an Odds Ratio(OR) of 1.14 (95% credible interval (Crl) of 0.82-1.56), residing in locations with a veterinary establishment vs. none (OR = 6.43, 95% Crl (4.97-8.35), providing care to dogs vs. allowing dogs to roam freely (OR = 2.38, 95% Crl(1.80-3.17) and owning a single dog vs multiple dogs (OR = 1.20, 95 Crl (0.92-1.56). Conversely, there was a decrease in the estimated probability of vaccination when comparing dog owners located in rural vs. urban areas (OR = 0.58, CrI 95% (0.43-0.78). Latent understanding, a measure of overall understanding of rabies virus, which we estimated using participant education levels and responses to questions about rabies epidemiology, was also an important predictor of vaccination probability (OR = 1.44, 95% Crl (1.04-2.07). The spatial analysis identified high-risk clusters for low vaccination in the cities of Moyamba, with a radius of 40 km, a relative risk (RR) of 1.10, and Bo, with a radius of 19.9 km with RR of 1.11. These data do not support Sierra Leone reaching the 2030 goal of human rabies elimination caused by dogs. Our study highlights a critical need for public outreach and education, improved vaccination rates, increased accessibility to veterinary services, and targeted interventions in Bo and Moyamba to support rabies prevention and control efforts.
