Conceptualizations of surge capacity are gaining traction in disaster preparedness and response, particularly in the context of critical and acute care during the pandemic as well as other disaster contexts. In most applications, the surge capacity domains describe the four types of assets required to ensure that surges in demand are addressed. Despite increasing interest and conceptual application, these constructs are yet to be considered or explored in relation to the profound resource scarcity and complex contexts of humanitarian health responses.
The aim of this research is to explore surge capacity domain constructs in the novel context of scarce health resource allocation in humanitarian health care response settings.
This research was conducted according to an exploratory qualitative design. Clinicians and managers with relevant experiences were purposively recruited to include broad perspectives across humanitarian responses and clinical specialties. Interview transcripts were analyzed using a latent deductive pattern approach, using a deductive code book consisting of existing surge capacity domains to explore surge capacity constructs. Analysis of coded data for cross-cutting themes drove identification of new findings regarding surge capacity in the context of humanitarian health responses.
Seventeen participants completed semi-structured interviews. In addition to demonstrating the relevance of existing surge capacity domains (staff, stuff, space, and systems; 4Ss), four new themes emerged: (1) sponsorship; (2) suitability; (3) security; and (4) supply. These four themes informed the conceptualization of surge capacity dimensions which must be satisfied for an asset to render a positive impact with relevance to all four surge capacity domains (4S - cumulative 4S domains and the new dimensions).
Although existing surge capacity domains have proven relevant to humanitarian health care response settings, this research produced a revised conceptualization of surge capacity constructs specific to this context. The identification of four surge capacity dimensions supported the conception and development of the Scarce Health Resource Allocation in Humanitarian Response Settings (SHARE-HRS) 4S model of surge capacity, thus offering a potential new tool to support humanitarian health response planning and evaluation.
在灾害防备与应对领域，特别是在大流行期间的重症和急症护理以及其他灾害背景下，激增能力的概念正越来越受到关注。在大多数应用中，激增能力领域描述了确保满足需求激增所需的四类资产。尽管人们对这些概念的兴趣日益增加且有了概念性应用，但在人道主义卫生应对中资源极度匮乏和情况复杂的背景下，这些结构尚未得到考虑或探讨。
本研究旨在探讨在人道主义医疗应对环境中稀缺卫生资源分配这一全新背景下的激增能力领域结构。
本研究采用探索性定性设计。有目的地招募了具有相关经验的临床医生和管理人员，以纳入涵盖人道主义应对和临床专业的广泛观点。使用潜在演绎模式方法对访谈记录进行分析，该方法使用由现有激增能力领域组成的演绎编码手册来探索激增能力结构。对编码数据进行交叉主题分析，从而确定在人道主义卫生应对背景下有关激增能力的新发现。
17名参与者完成了半结构化访谈。除了证明现有激增能力领域（人员、物资、空间和系统；4S）的相关性外，还出现了四个新主题：（1）赞助；（2）适用性；（3）安全；（4）供应。这四个主题为人道主义卫生应对背景下激增能力维度的概念化提供了依据，这些维度必须得到满足，资产才能在与所有四个激增能力领域（4S——累计4S领域和新维度）相关的方面产生积极影响。
尽管现有的激增能力领域已被证明与人道主义医疗应对环境相关，但本研究针对此背景提出了经修订的激增能力结构概念。确定的四个激增能力维度为人道主义应对环境中稀缺卫生资源分配（SHARE - HRS）激增能力4S模型的概念和开发提供了支持，从而提供了一个潜在的新工具，以支持人道主义卫生应对规划和评估。
