摘要

目的新冠肺炎大流行迫使各国考虑如何通过扩大外展服务来接触弱势社区,以提高疫苗接种率。作者创建了一个优化模型,以符合决策者的目标,即在有限的预算内最大限度地提高免疫覆盖率,并考虑经验数据和内生需求部署资源。设计/方法/方法混合整数计划(MIP)确定外展站点的位置以及卫生中心和外展站点的资源部署。作者使用冈比亚的一项案例研究,与联合国儿童基金会协商,验证了该模型并评估了该方法。冈比亚的研究结果表明,通过开设新的推广点并优化资源分配和时间表,卫生部可以在相同预算下将免疫覆盖率从91.0%提高到97.1%。案例研究解决方案为管理层提供了见解,即使不应用复杂的工具,也能推动疫苗覆盖率的提高。原创性/价值该研究以两种方式扩展了资源受限的LMIC疫苗分布建模文献:首先,将需求作为到卫生设施位置距离的函数进行内生计算,使疫苗网络能够围绕社区的便利性进行有效设计;其次,该模型的资源捆绑概念更准确、更灵活地表示了特定资源的复杂需求和成本,这促进了负责管理卫生预算的利益相关者的认同。该论文还展示了如何利用公开的人口和地理数据的实证研究和空间分析来有效地代表重要的背景因素。

Vaccine network design to maximize immunization coverage
PurposeThe COVID-19 pandemic has forced countries to consider how to reach vulnerable communities with extended outreach services to improve vaccination uptake. The authors created an optimization model to align with decision-makers' objective to maximize immunization coverage within constrained budgets and deploy resources considering empirical data and endogenous demand.Design/methodology/approachA mixed integer program (MIP) determines the location of outreach sites and the resource deployment across health centers and outreach sites. The authors validated the model and evaluated the approach in consultation with UNICEF using a case study from The Gambia.FindingsResults in The Gambia showed that by opening new outreach sites and optimizing resource allocation and scheduling, the Ministry of Health could increase immunization coverage from 91.0 to 97.1% under the same budget. Case study solutions informed managerial insights to drive gains in vaccine coverage even without the application of sophisticated tools.Originality/valueThe research extended resource constrained LMIC vaccine distribution modeling literature in two ways: first, endogenous calculation of demand as a function of distance to health facility location enabled the effective design of the vaccine network around convenience to the community and second, the model's resource bundle concept more accurately and flexibly represented complex requirements and costs for specific resources, which facilitated buy-in from stakeholders responsible for managing health budgets. The paper also demonstrated how to leverage empirical research and spatial analysis of publicly available demographic and geographic data to effectively represent important contextual factors.

期刊介绍: The Journal of Humanitarian Logistics and Supply Chain Management (JHLSCM) is targeted at academics and practitioners in humanitarian public and private sector organizations working on all aspects of humanitarian logistics and supply chain management. The journal promotes the exchange of knowledge, experience and new ideas between researchers and practitioners and encourages a multi-disciplinary and cross-functional approach to the resolution of problems and exploitations of opportunities within humanitarian supply chains. Contributions are encouraged from diverse disciplines (logistics, operations management, process engineering, health care, geography, management science, information technology, ethics, corporate social responsibility, disaster management, development aid, public policy) but need to have a logistics and/or supply chain focus. JHLSCM publishes state of the art research, utilizing both quantitative and qualitative approaches, in the field of humanitarian and development aid logistics and supply chain management.
