    背景:自2013年以来,哈萨克斯坦在数字健康实施方面取得了重大进展,从基于纸张的系统过渡到数字解决方案的广泛实施。然而,挑战依然存在,特别是现有数据收集要求与正在进行的数字转换之间的不一致。为了解决这个障碍,开始制定新的数字友好型医疗数据收集要求。
    方法:对健康和护理数据收集的所有现有要求进行比较分析,为采取进一步行动奠定了基础。一个专门的技术工作组,由卫生部设立,监督这个过程,一些专门的专家组参加了详细的讨论,以确保符合医疗保健需求。我们以立法法案为基础,强制使用从前数字时代继承的数据表格。大多数使用表单的数据元素被编目,检查一致性,标准化。ISO13940标准指导将刚性纸质表格转换为灵活的数字友好数据集。
    结果:对医疗保健立法的分析揭示了重要的优化机会。我们根据其内容和作用将157种表格分为四组,并着重于临床和管理记录进行转换。数据元素分析导致开发209个具有数据值的标准化分类。83个数据集,涵盖临床和管理领域,被开发来替代63种(共157种)形式。因此,为更好的数据和结构互操作性奠定了基础。
    结论:自上而下的数字健康标准化方法,结合开放市场政策,导致数据收集实践不一致。开发的数据集符合开发国家电子健康记录系统作为互操作性的推动者的目标,并为数字健康标准化增加了自下而上的视角。这项工作解决了数字数据模型开发缺乏指导的问题,然而,需要做出额外的努力来改变目前的做法,并最终将国家立法转变为数字友好模式。
    BACKGROUND: Kazakhstan has made significant strides in digital health implementation since 2013, transitioning from paper-based systems to wide implementation of digital solutions. However, challenges persist, notably the misalignment between existing data collection requirements and ongoing digital transformations. To address this obstacle, the development of a new digital-friendly requirements for health data collection at provider levels was initiated.
    METHODS: A comparative analysis of all existing requirements on health and care data collection set a foundation for further actions. A dedicated technical working group, established by the Ministry of Healthcare, oversaw this process, while several specialized expert groups participated in detailed discussions to ensure alignment with healthcare needs. We took as a basis the legislative act enforcing use of data forms inherited from pre-digital era. Data elements from most used forms were cataloged, checked for consistency, and standardized. ISO 13940 standard guided transformation of rigid paper-based forms into flexible digital-friendly data sets.
    RESULTS: Analysis of the healthcare legislation reveals significant optimization opportunities. We categorized 157 forms into four groups by their content and role and focusing on clinical and administrative records for transformation. Data elements\' analysis led to developing 209 standardized classifications with data values. 83 data sets, encompassing clinical and administrative domains, were developed to substitute 63 (out of 157) forms. Therefore, the foundation for better data and structure interoperability was set.
    CONCLUSIONS: The top-down approach to digital health standardization, combined with open market policies, results in inconsistent data collection practices. Developed data sets align with the goal of developing the national Electronic Health Records system as enabler for interoperability and adds a bottom-up perspective to digital health standardization. This effort addresses the lack of guidance for digital data model development, however additional efforts required to change the current practice and finalize the national legislation transformation into digital-friendly mode.

    方法:进行了文献综述,并在WebofKnowledge中运行了搜索策略,科学直接,翡翠,PubMed,Scopus和GoogleScholar搜索引擎作为跟踪参考的附加来源。我们找到了760份文件,排除314个重复项,关于摘要审查的339篇和关于全文审查的167篇;留下58篇论文供批判性评估。
    结果:目前的审查表明,14个标准被归类为健康信息系统数据质量的主要维度,包括:准确性,一致性,安全,及时性,完整性,可靠性,可访问性,客观性,相关性,可理解性,导航,声誉,效率和价值增加。准确性,完整性,和及时性,是文学中使用最多的三个维度。
    结论:目前,在评估卫生信息系统数据质量的维度上,缺乏统一性和潜在的适用性。通常,不同的方法(定性,定量和混合方法)用于评估所审查出版物中健康信息系统的数据质量。因此,由于定义维度和评估方法不一致,必须将数据质量的维度分类为有限的一组主要维度。
    BACKGROUND: Data quality in health information systems has a complex structure and consists of several dimensions. This research conducted for identify Common data quality elements for health information systems.
    METHODS: A literature review was conducted and search strategies run in Web of Knowledge, Science Direct, Emerald, PubMed, Scopus and Google Scholar search engine as an additional source for tracing references. We found 760 papers, excluded 314 duplicates, 339 on abstract review and 167 on full-text review; leaving 58 papers for critical appraisal.
    RESULTS: Current review shown that 14 criteria are categorized as the main dimensions for data quality for health information system include: Accuracy, Consistency, Security, Timeliness, Completeness, Reliability, Accessibility, Objectivity, Relevancy, Understandability, Navigation, Reputation, Efficiency and Value- added. Accuracy, Completeness, and Timeliness, were the three most-used dimensions in literature.
    CONCLUSIONS: At present, there is a lack of uniformity and potential applicability in the dimensions employed to evaluate the data quality of health information system. Typically, different approaches (qualitative, quantitative and mixed methods) were utilized to evaluate data quality for health information system in the publications that were reviewed. Consequently, due to the inconsistency in defining dimensions and assessing methods, it became imperative to categorize the dimensions of data quality into a limited set of primary dimensions.

    BACKGROUND: With the increasing number of protracted refugee crises globally, it is essential to ensure strong national health information systems (HIS) in displacement settings that include refugee-sensitive data and disaggregation by refugee status. This multi-country study aims to assess the degree of integration of refugee health data into national HIS in Jordan, Lebanon, and Uganda and identify the strengths and weaknesses of their national HIS in terms of collecting and reporting on refugee-related health indicators.
    METHODS: The study employs a comparative country analysis approach using a three-phase framework. The first phase involved reviewing 4120 indicators compiled from global health organizations, followed by a multi-stage refinement process, resulting in 45 indicators distributed across five themes. The second phase consisted of selecting relevant criteria from the literature, including data sources, annual reporting, disaggregation by refugee status, refugee population adjustments, accuracy, and consistency. The third phase involved assessing data availability and quality of the selected indicators against these criteria.
    RESULTS: Our analysis uncovered significant challenges in assessing the health status of refugees in Jordan, Lebanon, and Uganda, primarily stemming from limitations in the available health data and indicators. Specifically, we identified significant issues including incomplete local data collection with reliance on international data sources, fragmented data collection from various entities leading to discrepancies, and a lack of distinction between refugees and host populations in most indicators. These limitations hinder accurate comparisons and analyses. In light of these findings, a set of actionable recommendations was proposed to guide policymakers in the three countries to improve the integration of refugee health data into their national HIS ultimately enhancing refugees\' well-being and access to healthcare services.
    CONCLUSIONS: The current status of refugee-related health data in Jordan, Lebanon, and Uganda indicates the need for improved data collection and reporting practices, disaggregation by refugee status and better integration of refugee health data into national HIS to capture the health status and needs of refugees in host countries. Key improvement strategies include establishing a centralized authority for consistent and efficient data management, fostering transparent and inclusive data governance, and strengthening workforce capacity to manage refugee health data effectively.

    背景:尽管埃塞俄比亚在采用地区卫生信息系统版本2(DHIS2)进行国家汇总数据报告方面取得了显着进展,尚未对该系统的成熟度进行全面评估。
    目的:本研究旨在评估埃塞俄比亚DHIS2实施的成熟度水平,并提出一个路线图,以指导朝着更高的成熟度水平迈进。我们还旨在评估当前的成熟度状态,执行差距,以及在埃塞俄比亚实施DHIS2的未来方向。评估重点是数字卫生系统治理,熟练的人力资源,信息和通信技术(ICT)基础设施,互操作性,数据质量和使用。
    方法:通过咨询研讨会,在关键利益相关者的参与下,使用持续改进阶段工具进行了协作评估,以衡量5个核心领域的成熟度水平。13个组件,和39个子组件。5点量表(1=新兴,2=可重复,3=已定义,4=管理,和5=优化)用于衡量DHIS2实施成熟度水平。
    结果:国家DHIS2实施的成熟度水平目前处于定义阶段(分数=2.81),并计划到2025年移至可管理阶段(分数=4.09)。领域成熟度得分表明,除了ICT基础设施,处于可重复阶段(分数=2.14),其余4个结构域处于定义的阶段(分数=3).在国家一级制定标准化和基本的DHIS2进程,制定一项为期10年的战略计划,以指导包括DHIS2在内的数字卫生系统的实施,并在设施一级具备完成与DHIS2相关的特定任务所需的能力,这是迄今为止埃塞俄比亚卫生部的主要力量。缺乏支持DHIS2实施的劳动力能力准则;核心能力的不可用性(知识,技能,和能力)在卫生系统的所有级别完成DHIS2任务所需;以及ICT基础设施,例如该地区的通信网络和互联网连接,区域,和区域一级是该国有效实施DHIS2的主要障碍。
    结论:在持续改进阶段成熟度模型工具包的基础上,埃塞俄比亚DHIS2的实施状况处于确定的阶段,与其他4个领域相比,ICT基础设施领域处于最低阶段。到2025年,计划通过改善已识别的差距,将成熟度状态从定义阶段转移到管理阶段。建议采取各种行动点,以解决已确定的差距并达到规定的成熟度。负责任的机构,必要的资源,并列出了达到规定的成熟度级别所需的验证方法。
    BACKGROUND: Although Ethiopia has made remarkable progress in the uptake of the District Health Information System version 2 (DHIS2) for national aggregate data reporting, there has been no comprehensive assessment of the maturity level of the system.
    OBJECTIVE: This study aims to assess the maturity level of DHIS2 implementation in Ethiopia and propose a road map that could guide the progress toward a higher level of maturity. We also aim to assess the current maturity status, implementation gaps, and future directions of DHIS2 implementation in Ethiopia. The assessment focused on digital health system governance, skilled human resources, information and communication technology (ICT) infrastructure, interoperability, and data quality and use.
    METHODS: A collaborative assessment was conducted with the engagement of key stakeholders through consultative workshops using the Stages of Continuous Improvement tool to measure maturity levels in 5 core domains, 13 components, and 39 subcomponents. A 5-point scale (1=emerging, 2=repeatable, 3=defined, 4=managed, and 5=optimized) was used to measure the DHIS2 implementation maturity level.
    RESULTS: The national DHIS2 implementation\'s maturity level is currently at the defined stage (score=2.81) and planned to move to the manageable stage (score=4.09) by 2025. The domain-wise maturity score indicated that except for ICT infrastructure, which is at the repeatable stage (score=2.14), the remaining 4 domains are at the defined stage (score=3). The development of a standardized and basic DHIS2 process at the national level, the development of a 10-year strategic plan to guide the implementation of digital health systems including DHIS2, and the presence of the required competencies at the facility level to accomplish specific DHIS2-related tasks are the major strength of the Ministry of Health of Ethiopia so far. The lack of workforce competency guidelines to support the implementation of DHIS2; the unavailability of core competencies (knowledge, skills, and abilities) required to accomplish DHIS2 tasks at all levels of the health system; and ICT infrastructures such as communication network and internet connectivity at the district, zonal, and regional levels are the major hindrances to effective DHIS2 implementation in the country.
    CONCLUSIONS: On the basis of the Stages of Continuous Improvement maturity model toolkit, the implementation status of DHIS2 in Ethiopia is at the defined stage, with the ICT infrastructure domain being at the lowest stage as compared to the other 4 domains. By 2025, the maturity status is planned to move from the defined stage to the managed stage by improving the identified gaps. Various action points are suggested to address the identified gaps and reach the stated maturity level. The responsible body, necessary resources, and methods of verification required to reach the specified maturity level are also listed.

    背景:COVID-19大流行对医疗保健系统和服务产生了深远的影响,包括常规免疫(RI)。迄今为止,关于COVID-19大流行对塞拉利昂等西非国家RI的影响的信息有限,它已经经历了突发公共卫生事件,扰乱了它的医疗系统。这里,我们描述了COVID-19大流行对塞拉利昂关键抗原RI的影响。
    方法:我们使用了来自地区卫生信息系统的BCG疫苗接种数据,麻疹风疹1和2,以及五价1和3抗原。我们比较了国家和地区层面2019年、2020年、2021年和2022年选定抗原的年覆盖率。我们使用皮尔逊卡方检验评估了2019年与2020年、2020-2021年和2021-2022年的年度覆盖率差异。
    结果:全国所有抗原的覆盖率在2019-2020年下降,特别是麻疹-风疹1和五价3(-5.4%和-4.9%)。在2020年至2021年之间,覆盖率总体上升(+0.2%至+2.5%),除麻疹-风疹2例外(-1.8%)。麻疹-风疹抗原在2021-2022年反弹,而其他抗原的覆盖率下降了-0.5%至-1.9%。总的来说,2022年所有区级覆盖率均低于2019年。大多数地区在2019年至2022年期间有所下降,尽管有一些地区持续增加;一些地区在2020年至2021年期间有所增长/复苏;一些地区在2022年之前已经恢复了2019年的水平。
    结论:COVID-19大流行影响了塞拉利昂的国家卡介苗,麻疹-风疹,和五价抗原免疫,2022年没有完全恢复。大流行期间,大多数地区的覆盖率显着下降,尽管其中一些在2022年达到或超过2019年的比率。检查大流行的影响可以受益于在国家一级以外确定脆弱区域的重点。塞拉利昂大流行后RI的重建需要有针对性的战略和持续投资,以实现公平的获取和覆盖,以及预防疫苗可预防的疾病。
    BACKGROUND: The COVID-19 pandemic had a profound impact on healthcare systems and services, including routine immunization (RI). To date, there is limited information on the effects of the COVID-19 pandemic on RI in West African countries such as Sierra Leone, which had already experienced public health emergencies that disrupted its healthcare system. Here, we describe the impact of the COVID-19 pandemic on the RI of key antigens in Sierra Leone.
    METHODS: We used vaccination data from the District Health Information System for BCG, measles-rubella 1 and 2, and pentavalent 1 and 3 antigens. We compared 2019, 2020, 2021, and 2022 annual coverage rates for the selected antigens at the national and district levels. We used the Pearson chi-square test to assess the difference between annual coverage rates between 2019 and 2020, 2020-2021, and 2021-2022.
    RESULTS: National coverage rates for all antigens declined in 2019-2020, notably measles-rubella 1 and pentavalent 3 (-5.4% and - 4.9%). Between 2020 and 2021, there was an overall increase in coverage (+ 0.2% to + 2.5%), except for measles-rubella 2 (-1.8%). Measles-rubella antigens rebounded in 2021-2022, while others decreased between - 0.5 and - 1.9% in coverage. Overall, all district-level coverage rates in 2022 were lower than those in 2019. Most districts decreased between 2019 and 2022, though a few had a continuous increase; some had an increase/recovery between 2020 and 2021; some districts had recovered 2019 levels by 2022.
    CONCLUSIONS: The COVID-19 pandemic impacted Sierra Leone\'s national BCG, measles-rubella, and pentavalent antigen immunization, which were not fully restored in 2022. Most districts experienced notable coverage declines during the pandemic, though a few reached or surpassed 2019 rates in 2022. Examining pandemic impact can benefit from a focus beyond the national level to identify vulnerable regions. Sierra Leone\'s post-pandemic RI reestablishment needs targeted strategies and continual investments for equitable access and coverage, as well as to prevent vaccine-preventable diseases.
