Abstract
To efficiently allocate medical resources at disaster sites, medical workers perform triage to prioritize medical treatments based on the severity of the wounded or sick. In such instances, evaluators often assess the severity status of the wounded or sick quickly, but their measurements are qualitative and rely on experience. Therefore, we developed a wearable device called Medic Hand in this study to extend the functionality of a medical worker's hand so as to measure multiple biometric indicators simultaneously without increasing the number of medical devices to be carried. Medic Hand was developed to quantitatively and efficiently evaluate "perfusion" during triage. Speed is essential during triage at disaster sites, where time and effort are often spared to attach medical devices to patients, so the use of Medic Hand as a biometric measurement device is more efficient for collecting biometric information. For Medic Hand to be handy during disasters, it is essential to understand and improve upon factors that facilitate its public acceptance. To this end, this paper reports on the usability evaluation of Medic Hand through a questionnaire survey of nonmedical workers.

Abstract
During a disaster, all hospitals are expected to function as "social critical institutions" that protect the lives and health of people. In recent disasters, numerous hospitals were damaged, and this hampered the recovery of the affected communities. Had these hospitals business continuity plans (BCPs) to recover quickly after the disaster, most of the damage could have been avoided. This study conducted a scoping review of the historical trend and regional differences in hospital BCPs to validate the improvement of the BCP concept based on our own experience at Tohoku University Hospital, which was affected by the 2011 Great East Japan Earthquake and Tsunami (GEJET). We searched PubMed by using keywords related to BCP and adapted 97 articles for our analysis. The number of articles on hospital BCPs has increased in the 2000s, especially after Hurricane Katrina in 2005. While there are regional specificity of hazards, there were many common topics and visions for BCP implementation, education, and drills. From our 2011 GEJET experience, we found that BCPs assuming region-specific disasters are applicable in various types of disasters. Thus, we suggest the following integral and universal components for hospital BCPs: (1) alternative methods and resources, (2) priority of operation, and (3) resource management. Even if the type and extent of disasters vary, the development of BCPs and business continuity management strategies that utilize the abovementioned integral components can help a hospital survive disasters in the future.

Carrington MA, Ranse J, Hammad K. The impact of disasters on emergency department resources: review against the Sendai framework for disaster risk reduction 2015-2030. Australas Emerg Care 2020; 24:55-60. [PMID: 33032978 DOI: 10.1016/j.auec.2020.09.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 08/03/2020] [Accepted: 09/14/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Emergency departments (EDs) are often first to feel the intra-hospital effects of disasters. Compromised care standards during disasters eventuate from increased demands on health resources; the facilities, supplies, equipment and manpower imperative for a functioning healthcare facility. Emergency departments must understand the effect of disasters on their health resources. This paper examines the impact on resources within the ED as a result of a disaster and provides a review against the United Nations Office for Disaster Risk Reduction's Sendai Framework for Disaster Risk Reduction 2015-2030 priorities. METHOD An integrative literature review design was utilised. Articles were extracted from databases and search engines. The Preferred Reporting Items of Systematic reviews and Meta-Analysis Guidelines for systematic literature reviews were used. RESULTS Seven papers met inclusion criteria. Disaster consumable stocking was used to mitigate disaster risk and improve resilience. Logistical challenges were exacerbated by poor building design. Ineffective human resource management, communications failure, insufficient ED space, diminished equipment and supplies and unreliable emergency power sources were described. CONCLUSIONS Disaster planning and preparedness strategies can address health resource deficits, increasing ED resilience. Further retrospective case studies are required to greater understand the effects of disasters on ED health resources.

Five Challenges When Managing Mass Casualty or Disaster Situations: A Review Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17093068. [PMID: 32354076 PMCID: PMC7246560 DOI: 10.3390/ijerph17093068] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 04/16/2020] [Accepted: 04/22/2020] [Indexed: 12/15/2022]
Abstract
Background: Managing mass casualty or disaster incidents is challenging to any person or organisation. Therefore, this paper identifies and describes common challenges to managing such situations, using case and lessons learned reports. It focuses on sudden onset, man-made or technologically caused mass casualty or disaster situations. Methods: A management review was conducted based on a structured search in the PubMed and Web of Science databases. Results: The review included 20 case—and lessons learned reports covering natural disasters, man-made events, and accidents across Europe, the United States of Amerika (USA), Asia and the Middle East. Five common challenges were identified: (1) to identify the situation and deal with uncertainty, (2) to balance the mismatch between the contingency plan and the reality, (3) to establish a functional crisis organization, (4) to adapt the medical response to the actual and overall situation and (5) to ensure a resilient response. Conclusions: The challenges when managing mass casualty or disaster events involved were mainly related to the ability to manage uncertainty and surprising situations, using structured processes to respond. The ability to change mind set, organization and procedures, both from an organizational- and individual perspective, was essential. Non-medical factors and internal factors influenced the medical management. In order to respond in an effective, timely and resilient way, all these factors should be taken into consideration.

Water supply facility damage and water resource operation at disaster base hospitals in miyagi prefecture in the wake of the Great East Japan Earthquake. Prehosp Disaster Med 2015; 30:193-8. [PMID: 25665093 DOI: 10.1017/s1049023x15000084] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/07/2022]
Abstract
INTRODUCTION The aim of this study was to shed light on damage to water supply facilities and the state of water resource operation at disaster base hospitals in Miyagi Prefecture (Japan) in the wake of the Great East Japan Earthquake (2011), in order to identify issues concerning the operational continuity of hospitals in the event of a disaster. METHODS In addition to interview and written questionnaire surveys to 14 disaster base hospitals in Miyagi Prefecture, a number of key elements relating to the damage done to water supply facilities and the operation of water resources were identified from the chronological record of events following the Great East Japan Earthquake. RESULTS Nine of the 14 hospitals experienced cuts to their water supplies, with a median value of three days (range=one to 20 days) for service recovery time. The hospitals that could utilize well water during the time that water supply was interrupted were able to obtain water in quantities similar to their normal volumes. Hospitals that could not use well water during the period of interruption, and hospitals whose water supply facilities were damaged, experienced significant disruption to dialysis, sterilization equipment, meal services, sanitation, and outpatient care services, though the extent of disruption varied considerably among hospitals. None of the hospitals had determined the amount of water used for different purposes during normal service or formulated a plan for allocation of limited water in the event of a disaster. CONCLUSION The present survey showed that it is possible to minimize the disruption and reduction of hospital functions in the event of a disaster by proper maintenance of water supply facilities and by ensuring alternative water resources, such as well water. It is also clear that it is desirable to conclude water supply agreements and formulate strategic water allocation plans in preparation for the eventuality of a long-term interruption to water services.

Abstract
OBJECTIVE This study aimed to clarify the management of emergency electric power and the operation of radiology diagnostic devices after the Great East Japan Earthquake. METHODS Timing of electricity restoration, actual emergency electric power generation, and whether radiology diagnostic devices were operational and the reason if not were investigated through a questionnaire submitted to all 14 disaster base hospitals in Miyagi Prefecture in February and March 2013. RESULTS Commercial electricity supply resumed within 3 days after the earthquake at 13 of 14 hospitals. Actual emergency electric power generation was lower than pre-disaster estimates at most of the hospitals. Only 4 of 11 hospitals were able to generate 60% of the power normally consumed. Under emergency electric power, conventional X-ray and computed tomography (CT) scanners worked in 9 of 14 (64%) and 8 of 14 (57%) hospitals, respectively. The main reason conventional X-ray and CT scanners did not operate was that hospitals had not planned to use these devices under emergency electric power. Only 2 of the 14 hospitals had a pre-disaster plan to allocate emergency electric power, and all devices operated at these 2 hospitals. CONCLUSIONS Pre-disaster plans to allocate emergency electric power are required for disaster base hospitals to effectively operate radiology diagnostic devices after a disaster.

Abstract
OBJECTIVE A survey was conducted to describe the characteristics of patients treated for hypothermia after the Great East Japan Earthquake. METHODS Written questionnaires were distributed to 72 emergency medical hospitals in Miyagi Prefecture. Data were requested regarding inpatients with a temperature less than 36ºC admitted within 72 hours after the earthquake. The availability of functional heating systems and the time required to restore heating after the earthquake were also documented. RESULTS A total of 91 inpatients from 13 hospitals were identified. Tsunami victims comprised 73% of the patients with hypothermia. Within 24 hours of the earthquake, 66 patients were admitted. Most patients with a temperature of 32ºC or higher were treated with passive external rewarming with blankets. Discharge without sequelae was reported for 83.3% of patients admitted within 24 hours of the earthquake and 44.0% of those admitted from 24 to 72 hours after the earthquake. Heating systems were restored within 3 days of the earthquake at 43% of the hospitals. CONCLUSIONS Hypothermia in patients hospitalized within 72 hours of the earthquake was primarily due to cold-water exposure during the tsunami. Many patients were successfully treated in spite of the post-earthquake disruption of regional social infrastructure.

Abstract
OBJECTIVE To clarify advance measures for business continuity taken by disaster base hospitals involved in the Great East Japan Earthquake. METHODS The predisaster situation regarding stockpiles was abstracted from a 2010 survey. Timing of electricity and water restoration and sufficiency of supplies to continue operations were investigated through materials from Miyagi Prefecture disaster medicine headquarters (prefectural medical headquarters) and disaster base hospitals (14 hospitals) in Miyagi Prefecture after the East Japan earthquake. RESULTS The number of hospitals with less than 1 day of stockpiles in reserve before the disaster was 7 (50%) for electricity supplies, 8 (57.1%) for water, 6 (42.9%) for medical goods, and 6 (42.9%) for food. After the disaster, restoration of electricity and water did not occur until the second day or later at 8 of 13 (61.5%) hospitals, respectively. By the fourth postdisaster day, 14 hospitals had requested supplies from the prefectural medical headquarters: 9 (64.3%) for electricity supplies, 2 (14.3%) for water trucks, 9 (64.3%) for medical goods, and 6 (42.9%) for food. CONCLUSIONS The lack of supplies needed to continue operations in disaster base hospitals following the disaster clearly indicated that current business continuity plans require revision.
