Abstract

Background: Dust and Sand Storm (DSS), according to estimates by global reports, will increase dramatically in the Eastern Mediterranean Region (EMR). Numerous health problems caused by DSS will be severely affected regions and vulnerable groups. This study aimed to identify the components of the preparedness of health systems for the DSS phenomenon in EMR.
Methods: In this systematic review, the peer-reviewed papers in four electronic databases, including Medline through PubMed, Scopus, ISI Web of Science and the Cochrane library, as well as available grey literature, were searched and selected. The research process was carried out by including papers whose results were related to the potential health effects caused by desert dusts in EMR. Was used the combination of three groups of keywords: the exposure factor, health effects as outcomes, and the countries located in EMR. The focus was on the PRISMA checklist, with no time limitations until December 2017. Finally, through 520 related citations, 30 articles were included. Descriptive and thematic content analyses were evaluated.
Results: The preparedness components were divided into three and ten main categories and subcategories, respectively. The three categories covered the areas of DSS hazard identification, planning and policy-making, and risk assessment.
Conclusions: Recognition of the health system preparedness factors for DSS in EMR will help policy-makers and managers perform appropriate measures when dealing with this hazard. More studies should be conducted to understand these factors in other parts of the world.
Registration: PROSPERO registration number CRD42018093325.

Introduction

Dust and Sand Storms (DSS), as a natural disaster from the type of meteorological hazards1,2, affects the atmospheric system, air quality, and human health3–6. Over the recent years, the review studies have shown that there is a relation between the occurrence of the DSS and the incidence of human health7,8.

Based on the division by the World Health Organization (WHO), there are 22 countries in the Eastern Mediterranean Region (EMR)9. According to estimates from the Intergovernmental Panel on Climate Change (IPCC) report, EMR is one of the areas that will be strongly affected by this phenomenon in the future and will have potentially harmful health effects, especially on vulnerable groups10,11. Therefore, the best way to minimize the damage caused by the disasters is the preparedness for them12. The constant increasing risk of hazards indicates the need to integrate disaster risk reduction in preparedness, reinforce disaster preparedness, and provide assurance for timely utilization of the capacities13.

The epidemiological studies conducted on DSS mainly focus on the effects of the phenomenon on mortality and morbidity in humans14–20 or on the nature of major sources of dust phenomenon, the frequency, the duration and changes to the occurrence of the DSS, and the content of particulate matter (PM) suspended in the air8. Considering the DSS challenges on human health, drastic measures should be taken to ensure the health system is prepared for this phenomenon. In this regard, important elements have been proposed in the health system preparedness for disasters including the identification of hazards, the provision of Emergency Operation Plan (EOP), training and education, equipment, Early Warning System (EWS), information exchange, drill and exercise, monitoring, and evaluation13,21–28. On the other hand, there has not been a comprehensive study on the factors affecting the preparedness of the health system for dust phenomenon in EMR. Accordingly, the present study, through systematic review (SR), aims to investigate the factors affect the health system preparedness for the DSS in EMR and identify research gaps on the preparedness of the health system for DSS. The findings of the study, with proposed recommendations, can directly help health policymakers in preparedness promotion for this phenomenon, pave the way for further studies, and add to the richness of the current knowledge.

Methods

This study reports a SR based on the recommendations of the Cochrane and PRISMA guideline29. The PROSPERO registration number is CRD42018093325. A completed PRISMA checklist is available on figshare30.

Inclusion and exclusion criteria

All English-language articles related to effective factors on the preparedness of the health system for dust phenomenon in EMR were searched until December 2017. All methods of study, books, and theses that associated with the subject of this research were included. Papers in the form of the letter to the editor and studies that were merely related to the dust subject, and in which no mention of health outcome, were excluded, as were non-English-language articles, as were those without full-text access. Additionally, scientific documents related to non-desert origin (such as volcanic or anthropogenic sources) were not included.

Data sources

The international electronic databases investigated by authors (KA, ZGH, DKZ), including English sources from Medline through PubMed, Scopus, ISI web of science, Google Scholar, Cochrane library. The Eastern Mediterranean Health Journal and African Journals OnLine were also searched for published articles in the EMR. Other documents were extracted from reports published by organizations (such as the United Nations).

Search strategy

Following consultations with Library & Information Science (LIS) professionals in the health field, the search for articles was done using a combination of three groups of words in the databases mentioned above: The exposure factor (Dust Storm OR Sand Storm OR desert dust), health effects as outcomes (health OR morbidity OR mortality OR disease OR hospital OR respiratory OR cardiovascular OR coccidiomycosis OR meningococcal meningitis OR conjunctivitis OR dermatological OR transport accidents), and member states of the EMR (Middle East OR Afghanistan OR Bahrain OR Djibouti OR Egypt OR Iran OR Iraq OR Jordan OR Kuwait OR Lebanon OR Libyan Arab Jamahiriya OR Morocco OR Oman OR Pakistan OR Occupied Palestinian Territory OR Qatar OR Saudi Arabia OR Somalia OR Sudan OR Syrian Arab Republic OR Tunisia OR United Arab Emirates OR Yemen). These three groups of words were combined with "AND" together. The keywords were obtained from previous articles relating to the challenges of the health domain in connection with the DSS. In order to increase the probability of identification of all relevant literature, these keywords were selected based on an agreement of three researchers (KA, ZGH, and DKZ). The search words are used in titles, abstracts, and keywords of used articles. Figure 1 shows the search strategy.

Data collection process

In order to manage the citations, EndNote software, version X15, was used. All duplicate records became clear and removed. Using the title, abstract and, keywords screening, and given the inclusion criteria, the evaluation of documents was performed by two researchers (KA and ZGH). In the next step, the full text of the remaining articles was analyzed independently by the two researchers considering the inclusion and exclusion criteria and standard quality assessment. The papers were later examined in order to observe the points of the criteria for inclusion/exclusion by two other scholars (DKZ and RKJ). The quality of all articles was evaluated using the Cochrane handbook to evaluate the bias (Table 1)31. In this SR, the data extraction sheet was designed in two main parts. The first section covers the general specification of articles containing the ID, hyperlinks, title, electronic database, first author, publication year, country or region, method, population, and year/years of study. The second part was used to identify the main findings of articles, research suggestions related to this SR, and the preparedness components of the health system for the DSS. All extracted data were evaluated by members of the research team to verify accuracy and completeness.

Type of reporting
bias
Bias assessment across studies were done in this SR
Publication biasDuring the quality assessment, checked that have included two abstracts of the articles32,33 presented at
conferences, which have been published fully later. In this SR grey literatures (n= 206) and peer review articles
(n = 314) included in the study. Were also considered studies with positive (n=27) and negative (n=5) outcomes.
Two articles have both outcomes. It is important to note that access to full texts of some articles was limited
(n = 16); however, after reading the abstract the research team found that most of them did not have related
information about the aim of our systematic review.
Time lag biasFor positive and negative outcomes, the average per month, between submissions to published, was investigated
that it took 4.5 and 3, respectively. However, in this process, different factors can play a role.
Multiple (duplicate)
publication bias
The inclusion of multiple publications of the same study was checked within this SR; eventually, and no case
found.
Location biasThe citations published in the journals, with various Impact Factors (IF) (non – IF to IF= 4.61), were evaluated. The
studies with IF is less than one and non - IF as well as the articles with IF more than one were (n = 10, 33 %) and
(n= 20, 67 %), respectively. The purpose of this study was concentrated primarily on the EMR. Therefore, Only
articles in this area were reviewed.
Citation biasIn this SR, the research team tried to take into account the inclusion criteria when using other related references.
Also, were included both positive and negative outcomes to the SR.
Language biasOne of the inclusion criteria for this SR was the English language. We did not have the possibility of translating
other non - English languages, and this was the limitation of the study.
Outcome reporting biasGiven the objective of this SR, there was no possibility of exploring this type of bias. No RCT included to the SR.

Results

In general, through the implementation of the research strategy, the number of 520 records was found. In the last stage, 30 unique articles were obtained based on the inclusion/exclusion criteria (Figure 1). Data on the risk evaluation of bias are provided in Table 1. Final articles were examined in two parts, including descriptive and thematic content analysis. In Table 2, more details are presented about the imported literature to the SR. Findings indicate that since 2008, researchers have published more articles about the effects of the DSS on public health. Most articles related to Iran (17 articles, 56%). None of them had a qualitative approach. In thematic content analysis, based on literature review of studies that identify factors affecting the health system preparedness for various hazards21–28 and the multistage analysis by the research group, the preparedness components of health system for DSS in EMR were extracted and classified (Table 3).

DSS hazard identification

Health problems caused by DSS. Studies conducted in EMR showed that the prevalence of respiratory diseases (RD)17,34–43 and respiratory mortality (RM) is directly related to DSS17,40,41. Some of these studies focused on the incidence of asthma and pulmonary dysfunction in schoolchildren44. On the other hand, dust storms result in hospitalization due to cardiac diseases37,40,41,45 and cardiac mortalities (CM)40. Some of the various fungal species in EMR dust storms cause infectious diseases in human beings46 that increase or decrease allergic and asthma diseases47. Exposure to carcinogenic metals in PM10 increases the risk of cancer in citizens48. Other problems reported by the researchers were death and trauma due to the occurrence of storms (at a speed of 110 km/h) with dust particles49. Researchers found that as the concentration of DSS increases, the death caused by road traffic accidents (RTAs) decreases50. Studies conducted in Qatar showed that inhaling cyanotoxins found in DSS could have devastating effects on human health51,52. In contrast to these results, a number of researchers found that in general DSS had no effect on asthma, RD, RM18,45,53, CM18, and RTAs54.

Composition of DSS. The most abundant of bacteria observed in the dust particles were Bacillus spp.42,55,56, Staphylococcus spp., Streptomyces spp., Micrococcus spp.56 and Escherichia coli42. Also, most types of fungi were (Mycosporium spp.55 Penicillium, Aspergillus flavus, Cladosporium, Alternaria, Rhizopus, and Cladosporium)46,47, C. albicans42. The pollen grains caused allergies, identified from dust storms, in descending order, included Chenopodiaceous, Graminea, Pine, Artemisia, Palmae, Olea, and Typha42. No viruses were found in the dust particle samples42. On the other hand, the studies showed that the concentration of metals in dust increases in dusty days35. The main elements contained in the PM10 include (Na, Ca, Mg, Al, Fe)48,57. Among the carcinogenic metals in PM10 are Ni, Cr, As, and Cd57. According to studies conducted in Jordan and Saudi Arabia, dust samples contained considerable amounts of radioactivity58,59. Among other compounds reported in the desert dust are cyanobacteria toxins51,52.

Economic losses on health. The economic losses caused by the respiratory problems in Zabol, Iran, are estimated at about US$66 million32. The total damage estimated from DSS to the health system in Iran and Iraq amounted to US$306 million33.

Planning and policymaking

Education and training. The researchers emphasized that there should be health care recommendations for all affected individuals by DSS to reduce the vulnerability of population at risk, especially susceptible groups such as older persons, children, and cardiovascular and respiratory patients17,36,60. Also, providing community-based training is an important role in the proper functioning of the people after receiving a warning message related to DSS49.

Research. Scientific findings focused on this issue that further epidemiological studies should be conducted to identify chemical compounds and microorganisms in PM10, the baseline incidence values for each country, and the potential effects of DSS on health, especially long-term effects18,35,37,39,43,52–55,57,61. Moreover, there was no qualitative research among the studies reviewed.

Compilation of new and local indexes of air quality. Based on the assessment of PM-related health risks, researchers found that it is necessary to design new standards for local ambient air quality in the EMR61,62. Only limited countries such as Saudi Arabia, Bahrain and Jordan have an air pollution index relevant to their country61,63.

Comprehensive database development. To sum up the studies, provision of a comprehensive database of air pollutants and the effects of natural hazards, such as DSS, on health facilities is crucial for the benefit of policymakers and people57,64.

Prediction and warning. Based on the findings of the studies conducted in EMR, the deployment of EWS such as the network-based integrated system of forecast and forewarning (DuSNIFF) can be a good base and framework for a timely warning to the population at risk49,65. Conversely, other researchers reported that there is no need for a warning to the emergency department of hospitals in the event of DSS occurrence53.

Risk assessment

Use of hospital safety assessment tools. According to the assessment of Farsi Hospital Safety Index (FHSI), as a preparedness tool66,67, during different years in Iran, DSS was assessed as one of the highest probability of occurrence and health effects68.

Use models for health risk assessment of DSS. Based on the studies, health policymakers can find a better understanding of the health effects associated with PM10 peak times by using the findings of analytic models such as AirQ69 and generalized additive model (GAM)18,39.

Discussion

Preparedness for DSS in large-scale management and at the community level is one of the essential measures in the EMR. Provision of the necessary information such as the burden of diseases caused by DSS can be used in policy-making to focus on pre-disaster planning such as preparedness. The Hyogo Framework for Action (HFA) as an international strategy put emphasis on preparedness in order to produce effective response measures at all levels, to prioritize disaster risk reduction, and to reduce the background risk factors70. Preparedness needs to be preserved and dynamic and ongoing efforts21. Conducting research and producing scientific evidence relevant to disease burdens resulting from DSS can help to improve the health system preparedness for DSS71. Given that health disorders caused by climate change affect the pattern and changing the burden of disease in the community, therefore, having basic guidelines on preparedness will make optimal use of resources in health service delivery72,73. The health managers in EMR must develop their readiness based on the recognition of the burden of acute and long-term diseases and different dimensions of phenomenon. DSS preparedness requires a clear understanding and assessment of the country's situation. Health centers also need to be prepared regarding the personnel, equipment, medicine, and infrastructure.

The trained people that have greater understanding are more aware of the risks of hazards and in the event of a disaster, they act more appropriately74,75. One of the top priorities of the Sendai Framework for disaster risk 2015–2030 is the understanding of disasters in all their dimensions to allow appropriate measures to be taken for disaster preparedness. This framework is the result of consultations and intergovernmental negotiations that were encouraged by the United Nations Office for Disaster Risk Reduction13. Training, as one of the effective factors in the promotion of a disaster-preparedness culture, is essential in two levels: community-based education and training of health providers. Planning and doing regular drills in various scales is essential for the promotion of general and specialized education levels of the organizations and the people affected by this phenomenon. To enhance the understanding of disaster risk among managers and the community, awareness-raising programs should focus on capacity development through sharing previous experiences and lessons about preparedness for DSS. Also, the development of indigenous knowledge should be considered. For instance, in desert area, and not available to a mask, using of keffiyeh76,77 is recommended for protection from DSS.

With the purpose of planning for preparedness, regional policymakers must consider local considerations when using air quality indexes. Tsiouri et al.63 and Murena78 noted that different geographical regions have specific climatic conditions; therefore, this issue has an impact on atmospheric pollutants that affect human health as well as population responses to air pollution. As a result, the localization and adaptation of air pollution and its indicators can take place throughout the world. With the purpose of planning for preparedness, regional policymakers have to take into account that cannot be ignored local considerations when using air quality indexes63,78. To reduce the concerns, in light of valid regional evidence, the use of these standards should be reviewed.

Some studies in EMR18,45,50,53,54 and other regions of the world have shown that there is no association between the occurrence of dust and increasing health problems79–82. However, it is important to conclude that with increasing frequency, intensity and geographic expansion of DSS, it is necessary to ensure a timely and valid warning to vulnerable populations and groups16,83. Provision of advanced and accurate warning systems requires continuous efforts to improve air quality modeling and prediction73. Moreover, the results of various studies in the world show that early health warnings to vulnerable people about air pollution can reduce emergency visits to health centers through the reduction of outdoor activity during dusty days16,83.

The trans-boundary nature of DSS, unlike many natural hazards, is not limited to a specific geographic area; therefore, regional cooperation is needed to prepare for this phenomenon. In this regard, Kuwaiti scholars have suggested that it is essential to establish a regional committee54. The health system of the countries involved in DSS give priority to the development of regional health memorandums of understanding (MoU). In the framework of these MoUs, countries can strengthen regional and global collaboration as with UN and WMO to transfer modern technologies for prediction of DSS occurrences, exchange of medical knowledge, allocation of financial and technical assistance, combat against desertification, share of information and successful practical experiences, to form a regional credit union, and to build training workshops.

Strengths and limitations of the study

It can be noted, among the strengths of this study, the literature analysis performed with carefully assessing and have been done several times by the research team. Their research area was about Health in Disasters and Emergencies. The focus of this SR was on the EMR, as one of the most challenging areas, which has large DSS sources and creates regional health problems. A comprehensive study with this goal, so far, has not been conducted in this region. However, in this SR, only English articles related to EMR were included, the number of articles related to dust and health field was limited, and the full text of some studies was not accessible.

Conclusion

The burden of diseases caused by dust in EMR shows the need to undertake measures for government preparedness to protect the health of affected. Given that DSS is a large-scale hazard, to gain preparedness, countries should move towards regional and international cooperation. The health system needs to develop a comprehensive plan of readiness to improve the effectiveness of the response measures. Also, regular exercises in all scales are a very important component. To increase public health recommended the development of dust-health EWS. Promotion of preparedness culture and the increase of public awareness about the effects of DSS through public media are suggested. In preparedness programs, the participation of the community is recommended. Health workers should receive regular training on cardiovascular and respiratory problems. Further quantitative and qualitative researches to identify the nature of DSS and adaptive factors can help bridge the gap between scientific findings and preparedness measures. Although we addressed preparedness in this study, there should be a comprehensive plan to manage the hazard and to consider all the loops of the disaster risk management cycle. In general, this study can help policy-makers of the health system in disaster risk management to identify factors that are effective in preparedness for DSS and to take the necessary preparedness measures.
