Introduction

The most significant consequences of disasters are health impacts that occur in the aftermath [1]. Natural disasters such as earthquakes and floods not only have a detrimental impact on an individual’s health but also result in significant damage to the healthcare sector, reducing its capacity to respond and recover effectively. This, in turn, leads to a rise in mortality and morbidity rates [2, 3]. Disasters directly damage the physical structure of hospitals, clinics, and healthcare centers and indirectly affect the health sector by destroying community infrastructure, such as water, electricity, fuel, transportation, and communication systems. Additionally, disasters can impact healthcare providers and their families [4, 5].

Providing essential health services is challenging during disasters because of infrastructure failure and the inefficiency of healthcare centres [6]. It is evident that the health centres play a pivotal role in alleviating the negative consequences that arise in the aftermath of disasters. Therefore, it is of paramount importance to ensure the uninterrupted functioning of this vital infrastructures [7,8,9]. Comprehending the health consequences of disasters provides the basis for identifying demands, improving capacity, and providing opportunities for reconstruction and future disaster risk reduction [10].

The convergence of four seminal accords on disaster risk reduction, development finance, sustainable development, and climate change at the end of 2015 presented a singularly promising opportunity to achieve coherence across related policy domains. The Sendai Framework for Disaster Risk Reduction represents the global policy framework of the United Nations from 2015 to 2030. This represents a significant advance in global policy coherence concerning health, development, and climate change [11,12,13]. One of the principal objectives of the Sendai Framework is to enhance disaster preparedness for an effective response and “build back better“(BBB) in recovery [14].

The scope of disaster recovery is broader than that of response. In the context of the health system, recovery is defined as the reconstruction, restoration, and upgrading of the components of a country’s health sector and the main functions of public health, in accordance with the BBB principle and the goals of sustainable development [15]. For an optimal reconstruction, it is necessary to develop a legal, technical, and comprehensive framework. The success of a reconstruction program depends on an accurate assessment of the damage, loss, and needs of the post-disaster area to determine the approaches, goals, priorities, and measures required for reconstruction [2].

The post-disaster reconstruction of the health system in developing countries is hindered by some factors, including a lack of knowledge and expertise, limited budget and planning, political competition, fraud, and embezzlement or misuse of social benefits [3, 16]. Considering the argument of ‘humanitarian ignorance’, In light of the argument put forth by scholars who refer to this phenomenon as “humanitarian ignorance,“ [17], it can be argued that this “knowledge” does exist and that it is purposeful ignorance of said knowledge.

In 2008, the European Union, World Bank, and United Nations Development Group implemented a standard post-disaster assessment approach and developed a comprehensive and collaborative post-disaster assessment program [18]. In damage and loss assessments, experts in each sector calculate post-disaster damage and loss, which are essential in reconstruction programs [19, 20].

Chapin et al. (2009) studied the impact of the 2007 Ica earthquake on healthcare facilities in southern Peru. They reported that after an earthquake of magnitude 7.9 in Peru, 60% of the health centers in the region were affected to the degree that they were unable to provide client services. This study revealed that reports of damage assessments in a single disaster were sometimes not the same [21]. Achour et al. (2020) evaluated hospital performance after the 2016 Kumamoto Earthquake in Japan. Data analysis revealed that the impaired function of some healthcare centers in the affected areas significantly affected the health needs of the local communities [22].

Similar to other social sectors, the disaster impacts on the healthcare sector is considerable and is one of the concerns of managers and experts in the healthcare sector. In light of the pivotal role of the health sector in post-disaster response and recovery, as well as in the development of a post-disaster reconstruction program, it is crucial to conduct a thorough assessment of damage and losses incurred following a disaster. A post-disaster damage and loss assessment in the health sector can serve as a foundation for the creation of a coherent and integrated framework for health reconstruction. The absence of a post-disaster damage and loss assessment program may result in certain requirements being overlooked, the results of which are not deemed acceptable, facilities being allocated on a non-prioritized basis, and there being no basis for monitoring the implementation of plans and activities. Assessment is a demanding and decisive management task that is effective in decision-making, planning, monitoring, handling a program, and taking coherent actions. Post-disaster damage and loss assessment has a direct impact on decision-making, planning, monitoring of responses, and the implementation of recovery operations. Consequently, these assessments must be purposeful and scheduled.

Review objective and research questions

This scoping review was conducted to identify the entities and components of post-disaster damage and loss assessment programs in the healthcare sector. The PCC framework, which includes the participants, concepts, and context recommended by the Joanna Briggs Institute, was used to develop the research question [23]. The research question for this scoping review is as follows: what information is available about the entities and components of the healthcare sector’s post-disaster damage and loss assessment program?

Methods

A knowledge gap exists in the field of post-disaster damage and loss assessment in the healthcare sector. To address this issue, the most appropriate methodology for achieving the study’s objective was identified as a scoping review. This systematic scoping review was conducted under the proposed Joanna Briggs Institute method [24]. The study included the following steps: defining and aligning the research objectives and questions, developing the inclusion and exclusion criteria, describing the planned approach to the evidence search, study selection, data extraction, presentation of the evidence, searching for evidence, selecting the evidence, extracting the evidence, analyzing the evidence, presenting the results, and summarizing the evidence [23]. The study protocol was registered in the Open Science Framework on 4 June 2022 [25] and was published in BMJ Open [26]. The Preferred Reporting Items for Systematic Reviews extension for Scoping Reviews (PRISMA-ScR Checklist 1) [27] checklist was used to report the results of this scoping review.

Inclusion and exclusion criteria

In keeping with the scoping review methodology, our inclusion criteria (Table 1) were broad, and our search was comprehensive in capturing the entities and components of the healthcare sector’s post-disaster damage and loss assessment program. We included literature reviews, primary empirical articles, case studies, opinion pieces, and editorials published in English or Persian “due to geographical focus, and researcher language skills”. In addition, grey literature related to the study objective, including dissertations, organizational documents, post-disaster assessment reports, and guidelines, was searched and reviewed. Table 2 presents a distribution of studies by location, organization, and document type.

Search strategy

The search strategy was drafted with the help of an experienced informaticist librarian and was further refined through team discussion. Initially, a primary search was conducted on the Google Scholar, PubMed, World Bank, and PreventionWeb websites. The following concepts were extracted from the documents: post-conflict consequences in health systems, disaster impacts on the healthcare sector, post-disaster damage and loss assessment, post-earthquake hospital functionality, post-disaster damage and loss assessment, disaster damage, operational status of healthcare facilities during a hurricane, and the impacts of extreme events. An appropriate search strategy was used for each database (Table 3).

Study selection

We searched all English and Persian articles published from 2010 to 2022 on the Web of Science, PubMed, Scopus, ProQuest, Google Scholar, and Magiran databases. Our search started on 20 January 2022. The search results were imported into Endnote X9 software. After removing the duplicates, J. Miri checked all the remaining titles to remove unrelated documents. The titles and abstracts of the remaining articles were independently examined by two authors (J. Miri and A.R. Raeisi) to reach a common understanding of the selection criteria, discussion of disagreements, and definition of the inclusion and exclusion criteria. The remaining articles were uploaded to Rayyan software to facilitate record screening. The full texts of articles whose abstracts did not meet the exclusion criteria or were ambiguous were reviewed. Discrepancies in inclusion or exclusion decisions were resolved through discussion (G. Atighechian). Finally, the reference lists were checked to identify relevant studies. In the grey literature search, researchers also investigated organizations’ websites related to disaster management, such as the UNDP, World Bank, UNDRR, International Recovery Platform, PreventionWeb, WHO, and FEMA.

Data extraction

Supplementary Tables 1 and 2 show the characteristics of the articles and grey literature discussed in this study. General information (title, authors, publication year, study location, and key findings) regarding the questions addressed in this scoping review was extracted from the selected studies. Two independent reviewers extracted all relevant information and any discrepancies were resolved through discussion.

Data analysis and presentation

The documents were organized and analyzed by the researchers using the MAXQDA 2020 software. The data analysis strategy employed at this juncture was a thematic analysis approach. Thematic analysis is a valuable approach for elucidating experiences, thoughts, or behaviors within a data set. Additionally, researchers have proposed that thematic analysis is an optimal analytical method for novice qualitative researchers due to its transparent and straightforward procedures [28, 29].

Results

The search of the related electronic databases led to the identification of 845 articles. After removing the duplicates, 826 studies remained. The titles were screened, and 102 potentially eligible articles were selected. The simultaneous title and abstract review by two independent reviewers led to the selection of 80 articles that were uploaded to Rayyan software. Finally, 41 articles were selected for full-text review. The grey literature search identified 1015 documents, reports, manuals, and guidelines based on the inclusion and exclusion criteria and the study objectives, and 23 documents were selected for review.

Researchers have classified resources into five categories: articles, books, dissertations, policy documents, and reports. Studies have been conducted in different countries, half of which have been published in the last five years. The findings were categorized into five main themes, 20 subthemes, and 876 codes according to the research objectives and questions. The main themes, subthemes, and some related codes are presented in (Table 4).

Discussion

This study provides a comprehensive perspective on post-disaster damage and loss assessment in the healthcare sector. To achieve a common understanding of post-disaster damage and loss assessment in the healthcare sector, the researchers first collected definitions and related concepts. Then, organized concepts related to damage and loss assessment teams, damage and loss assessment stages, data collection elements, assessment tools, and programs. The paper concludes with a discussion of the linkages between the healthcare sector and other sectors affected by disasters.

The health system comprises a wide range of organizations, institutions, groups, and individuals in governmental and nongovernmental sectors that policy, produce resources, finance, and provide health services to restore, promote, and maintain public health [30]. According to the WHO framework, the health system comprises six building blocks; service delivery, health workforce, information, medical products, vaccines and technologies, financing, leadership, and governance [31, 32]. The realization and promotion of community health and fair cooperation in providing resources are crucial goals of the health system and are considered fundamental in most countries [33].

The continuity of services is critical in some businesses, such as those in the healthcare sector. However, these trends can be disrupted by disasters [34]. Achour et al. (2020) evaluated hospital performance after the 2016 Kumamoto Earthquake in Japan. The occurrence of this event resulted in a disruption to the continuity of healthcare services. The investigation revealed that the primary causes of the disruption were damage to the infrastructure, including buildings, critical systems, and medical equipment. The results of the study indicated a 15% reduction in healthcare functionality in the affected regions [22]. In the study by Gufue et al. (2024), the direct economic loss to the health system caused by war-related looting or vandalism in the Tigray region of Northern Ethiopia was quantified in excess of $511 million. The assessment revealed that 80.6% of health posts, 73.6% of health centres, 80% of primary hospitals, 83.3% of general hospitals and two specialized hospitals were damaged and/or vandalized either fully or in part due to the war [35]. Therefore, a disaster recovery plan in the healthcare sector is essential for providing necessary measures and minimizing disaster consequences, And international frameworks such as Sendai play an important role in this regard and emphasize the need to develop and implement measures for disaster risk reduction and vulnerability [36, 37].

For reconstruction, a reliable post-disaster damage and loss assessment method is required. The diversity of approaches and assessment-related outputs have led to various challenges. A significant obstacle to post-disaster damage and loss assessment is access to consistent, dependable, and detailed data on the impact of disasters. Establishing guidelines for reporting post-disaster damage and loss assessments is necessary to help national and regional institutions collect information in a structured manner [38]. Accurate data on disaster damage and losses are crucial for effective risk management, including loss accounting, disaster forensics, and risk analysis [39]. Assessment information is pivotal for effective policy development, resource allocation, and disaster preparedness [40]. We can improve disaster management and link disaster management science to disaster risk reduction policymaking by using these data [38].

In the Kermanshah Earthquake Lessons Learned study conducted by Khankeh et al. (2018) in Iran, it was recommended that a standard protocol be established for the receipt of reports from disaster locations in the initial days and weeks following an earthquake. Moreover, the establishment of rapid assessment teams at the local, regional, and national levels, with specific guidelines, was considered a crucial step [41]. The composition of the assessment team depends on the sector to be assessed. Healthcare sector assessment teams from different disciplines, including public health experts, physicians, epidemiologists, architects, civil engineers, and health economists, can estimate the value of production losses [18, 31, 42].

The post-disaster damage and loss assessment methodology includes pre-disaster baseline data collection, disaster effects, impact analysis, recovery needs estimation, and strategies that recommend appropriate interventions, implementation arrangements, and policies [43]. Documentation of damage and loss assessments should begin as soon as possible after a disaster [44]. A post-disaster damage and loss assessment report is a live document that is revised as better data become available [45]. Post-disaster damage and loss assessment reports should differ according to the assessment stage and type of disaster [46].

There is the fact that all societies and countries are susceptible to disasters. The primary responsibility for disaster and emergency management is affected by local communities and countries. After a disaster, the healthcare sector faces multiple hazards, limited resources for dealing with them, and high expectations regarding their performance. Multiple stakeholders engage in post-disaster damage and loss assessments and their interventions are guided by various damage and loss assessment methods. Such variations in techniques and related assessment outputs challenge the comparability across assessments and often present conflicting images. Despite the long history of reconstruction in Iran, there are numerous challenges in assessing post-disaster damage and loss. Therefore, there is a need to develop a set of post-disaster damage and loss assessment frameworks, including methodologies and guidelines, for the healthcare sector.

Limitation

Limited scientific resources for disaster damage assessment in the healthcare sector, access to imperative content, and documentation in the country were limitations of this study. As with all scoping reviews, we did not formally evaluate the quality of the evidence, and because of the varying nature of the studies, only a limited synthesis of results was possible.

Conclusion

In light of the pivotal role of the post-disaster healthcare sector, it is of the utmost importance to develop appropriate post-disaster damage and loss assessment programme that can be adapted to different socio-cultural contexts and varying resources. To date, there have been few studies that have discussed the entities and components of disaster damage and loss assessment programme in the healthcare sector. It was, however, determined that identifying the entities and components of the healthcare sector’s post-disaster damage and loss assessment program was a necessary step for advancing the healthcare sector in Iran. This review offers a detailed examination of post-disaster damage and loss assessment programs within the healthcare sector.
