Health care institutions constantly must be prepared for disaster response. However, there are deficiencies in the current level of preparedness. The aim of this study was to investigate the factors affecting the perception of health care workers (HCWs) towards individual and institutional preparedness for a disaster.
Methods
A survey on disaster incident preparedness was conducted among doctors, nurses, and allied health workers over a period of two months in 2010. The survey investigated perceptions of disaster preparedness at the individual and institutional level. Responses were measured using a five-point Likert scale. The primary outcomes were factors affecting HCWs’ perception of institution and individual preparedness. Secondary outcomes were the proportions of staff willing to participate and to place importance on disaster response training and their knowledge of access to such training. Data was analyzed using descriptive statistics. Logistic regression was performed to determine the factors that influenced the HCWs’ perception of their individual and institutional readiness. Odd ratios (ORs) of such factors were reported with their 95% confidence intervals (CIs).
Results
Of 1700 HCWs, 1534 (90.2%) completed the survey. 75.3% (1155/1534) felt that the institution was ready for a disaster incident, but only 36.4% (558/1534) felt that they (as individuals) were prepared. Some important factors associated with a positive perception of institution preparedness were leadership preparedness (OR = 13.19; 95% CI, 9.93-17.51), peer preparedness (OR = 6.11; 95% CI, 4.27-8.73) and availability of training opportunities (OR = 4.76; 95% CI, 3.65-6.22). Some important factors associated with a positive perception of individual preparedness were prior experience in disaster response (OR = 2.80; 95% CI, 1.99-3.93), institution preparedness (OR = 3.71; 95% CI, 2.68-5.14), peer preparedness (OR = 3.49; 95% CI, 2.75-4.26), previous training in disaster response (OR = 3.48; 95% CI, 2.76-4.39) and family support (OR = 3.22; 95% CI, 2.54-4.07). Most (80.7%, 1238/1534) were willing to participate in future disaster incident response training, while 74.5% (1143/1534) felt that being able to respond to a disaster incident constitutes part of their professional competency. However, only 27.8% (426/1534) knew how to access these training opportunities.
Conclusions
This study demonstrated that HCWs fare poorly in their perception of their individual preparedness. Important factors that might contribute to improving this perception at the individual and institution level have been identified. These factors could guide the review and implementation of future disaster incident response training in health care institutions.

The newer cyanide antidote, hydroxocobalamin, due to its pigmentation, has been found to cause interferences in some laboratory assays. Co-oximetry may also be affected by hydroxocobalamin, leading to false elevations in hemoglobin concentration, methemoglobin, carboxyhemoglobin, and false decreases in oxyhemoglobin. The Masimo Radical-7 is a medical device that performs noninvasive oximetry and estimates hemoglobin (Hb) concentration and percent carboxyhemoglobin (COHb), methemoglobin (MetHb), and oxyhemoglobin saturation (O2Hb).
Study Objectives
The study sought to determine the effect of hydroxocobalamin on noninvasive measurement of hemoglobin indices using the Masimo Radical-7 monitor.
Methods
Seven asymptomatic volunteers who were unexposed to cyanide had baseline heart rate (HR), blood pressure (BP), and oximeter measurements recorded followed by an infusion of five grams of hydroxocobalamin over 15 minutes. The above parameters were subsequently recorded at: 5, 10, 15, 30 and 60 minutes post infusion. Data were analyzed by calculating the area under the curve (AUC) for each variable and comparing the results to expected values by paired t tests. Expected AUC values were calculated by extrapolating baseline values across the entire time period.
Results
The mean differences from baseline values with 95% confidence intervals and t tests of mean difference were: SBP: 11 mm Hg (95% CI, 0-22; P = .051); HR: -9 (95% CI, -15 to -3; P = .01); Hb: -0.1 (95% CI, -0.7 to 0.4; P = .57); O2Hb: 0 g/dL (95% CI, -1 to 1; P = .41); COHb: -1 (95% CI, -3 to 1; P = .25); MetHb: -0.2 (95% CI, -0.3 to 0; P = .03).
Discussion
After infusion of hydroxocobalamin there was a significant elevation of systolic blood pressure and decrease in heart rate. There were no significant differences in Hb, O2Hb, and COHb. Although percent methemoglobin concentrations were statistically lower, the authors feel this difference is of trivial clinical significance.
Conclusion
The administration of hydroxocobalamin does not significantly impact noninvasive oximetry.

Providing comprehensive emergency preparedness training (EPT) to care providers is important to the future success of disaster operations in the US. Few EPT programs possess both competency-driven goals and metrics to measure performance during a multi-patient simulated disaster.
Methods
A 1-day (8-hour) EPT course for care providers was developed to enhance provider knowledge, skill, and comfort necessary to save lives during a simulated disaster. Nine learning objectives, 18 competencies, and 34 performance objectives were developed. During the 2-year demonstration of the curriculum, 24 fourth-year medical students and 17 Veterans Hospital Administration (VHA) providers were recruited and volunteered to take the course (two did not fully complete the research materials). An online pre-test, two post-tests, course assessment, didactic and small group content, and a 6-minute clinical casualty scenario were developed. During the scenario, trainees working in teams were confronted with three human simulators and 10 actor patients simultaneously. Unless appropriate performance objectives were met, the simulators “died” and the team was exposed to “anthrax.” After the scenario, team members participated in a facilitator-led debriefing using digital video and then repeated the scenario.
Results
Trainees (N = 39) included 24 (62%) medical students; seven (18%) physicians; seven (18%) nurses; and one (3%) emergency manager. Forty-seven percent of the VHA providers reported greater than 16 annual hours of disaster training, while 15 (63%) of the medical students reported no annual disaster training. The mean (SD) score for the pre-test was 12.3 (3.8), or 51% correct, and after the training, the mean (SD) score was 18.5 (2.2), or 77% (P < .01). The overall rating for the course was 96 out of 100. Trainee self-assessment of “Overall Skill” increased from 63.3 out of 100 to 83.4 out of 100 and “Overall Knowledge” increased from 49.3 out of 100 to 78.7 out of 100 (P < .01). Of the 34 performance objectives during the disaster scenario, 23 were completed by at least half of the teams during their first attempt. All teams except one (8 of 9) could resuscitate two simulators and all teams (9 of 9) helped prevent anthrax exposure during their second scenario attempt.
Conclusions
The 1-day EPT course for novice and experienced care providers recreated a multi-actor clinical disaster and enhanced provider knowledge, comfort level, and EPT skill. A larger-scale study, or multi-center trial, is needed to further study the impact of this curriculum and its potential to protect provider and patient lives.

One of the important tenets of emergency preparedness is that planning for disaster response should resemble standard operating procedure whenever possible. Electronic order entry has become part of the standard operating procedures of most institutions but many of these systems are either too cumbersome for use during a surge or can even be rendered non-functional during a sudden patient surge such as a mass-casualty incident (MCI). Presented here is an experience with delayed radiology order entry during a recent MCI and the after action programming of the system based on this real experience. In response to the after action analysis of the MCI, a task force was assigned to solve the MCI radiology order entry problem and a solution to streamline disaster image ordering was devised. A “browse page” was created that lists every x-ray and every CT scan that might be needed in such an event with all required information defaulted to “Disaster.” This created a way to order multiple images for any one patient, with 40% time saving over standard electronic order entry. This disaster radiology order entry solution is an example of the surge preparedness needed to promote patient safety and efficient care delivery as the widespread deployment of electronic health records and order entry continues across the United States.

Following the Great East Japan Earthquake on March 11, 2011, the Japan Medical Association deployed medical disaster teams to Shinchi-town (population: approximately 8,000), which is located 50 km north of the Fukushima Daiichi nuclear power plant. The mission of the medical disaster teams sent from Fukuoka, 1,400 km south of Fukushima, was to provide medical services and staff a temporary clinic for six weeks. Fear of radiation exposure restricted the use of large medical teams and local infrastructure. Therefore, small volunteer groups and a cloud-hosted, web-based electronic health record were implemented. The mission was successfully completed by the end of May 2011. Cloud-based electronic health records deployed using a “software as a service” model worked well during the response to the large-scale disaster.

The health of people with chronic medical conditions is particularly vulnerable to the disruptions caused by public health disasters, especially when there is massive damage to the medical infrastructure. Government agencies and national organizations recommend that people with chronic illness prepare for disasters by stockpiling extra supplies of medications.
Problem
A wide range of chronic illnesses has long been documented among veterans of the US armed forces. Veterans with chronic illness could be at great risk of complications due to disaster-related medication disruptions; however, the prevalence of personal medication preparedness among chronically ill veterans is not currently known.
Methods
Data was used from the 2009 California Health Interview Survey on 28,167 respondents who reported taking daily medications. After adjusting for differences in age, health status, and other characteristics, calculations were made of the percentage of respondents who had a two-week supply of emergency medications and, among respondents without a supply, the percentage who said they could obtain one. Veteran men, veteran women, nonveteran men, and nonveteran women were compared.
Results
Medication supplies among veteran men (81.9%) were higher than among nonveteran women (74.8%; P < .0001) and veteran women (81.1%; P = 0.014). Among respondents without medication supplies, 67.2% of nonveteran men said that they could obtain a two-week supply, compared with 60.1% of nonveteran women (P = .012).
Discussion
Among adults in California with chronic illness, veteran men are more likely to have personal emergency medication supplies than are veteran and nonveteran women. Veteran men may be more likely to be prepared because of their training to work in combat zones and other emergency situations, which perhaps engenders in them a culture of preparedness or self-reliance. It is also possible that people who choose to enlist in the military are different from the general population in ways that make them more likely to be better prepared for emergencies.
Conclusion
Veterans in California have a relatively high level of emergency medication preparedness. Given the health complications that can result from disaster-related medication disruptions, this is a promising finding. Disasters are a national concern, however, and the personal preparedness of veterans in all parts of the nation should be assessed; these findings could serve as a useful reference point for such work in the future.

The prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization among Emergency Medical Services (EMS) personnel is not well studied. Methicillin-resistant Staphylococcus aureus colonization can be a health hazard for both EMS personnel and patients. The aim of this study was to quantify the prevalence of MRSA colonization among EMS personnel. This study will help the scientific community understand the extent of this condition so that further protocols and policies can be developed to support the health and wellbeing of EMS personnel.
Hypothesis/ Problem
The hypothesis of this study was that the prevalence of MRSA colonization among EMS personnel is significantly higher than among the general population.
Methods
This was a cross-sectional study. A total of 110 subjects were selected from two major US Mid-Atlantic fire departments. Methicillin-resistant Staphylococcus aureus colonization was detected by nasal swabbing. Nasal swabs were inoculated onto a special agar medium (C-MRSAgar) with polymerase chain reaction testing performed. One-sided binomial distribution at the StudySize 2.0 Web calculator was used. Using the Web calculator, p (H0 proportion) = 1.5%; a difference (H1-H0) ‘Δ’ = 4.53% can be detected at α = 5% and power = 80% with N = 110.
Results
Samples were collected from 110 volunteers. Seven samples were positive for MRSA, resulting in a prevalence of 7/110 or 6.4% (95% CI, 1.8%-11%; P < .0003) compared with a 1.5% prevalence of MRSA colonization among the general population.
Conclusion
There is evidence that EMS personnel have a higher prevalence of MRSA colonization than the general population. This can be a risk to patients and can be recognized as an occupational hazard.

Very little is known on the impact of recurrent disasters on mental health.
Aim
The present study examines the immediate impact of a recurrent flood on mental health and functioning among an affected population in the rural district of Bahraich, Uttar Pradesh, India, compared with a population in the same region that is not affected by floods.
Methods
The study compared 318 affected respondents with 308 individuals who were not affected by floods. Symptoms of anxiety and depression were assessed by the Hopkins Symptom Checklist-25 (HSCL-25). Psychological and physical functioning was assessed by using the Short Form-12 (SF-12).
Results
The affected group showed large to very large differences with the comparison group on symptoms of anxiety (D = .92) and depression (D = 1.22). The affected group scored significantly lower on psychological and physical functioning than the comparison group (respectively D = .33 and D = .80). However, hierarchical linear regressions showed no significant relationship between mental health and the domains of functioning in the affected group, whereas mental health and the domains of functioning were significantly related in the comparison group.
Conclusion
This study found a large negative impact of the recurrent floods on mental health outcomes and psychological and physical functioning. However, in a context with recurrent floods, disaster mental health status is not a relevant predictor of functioning. The findings suggest that the observed mental health status and impaired functioning in this context are also outcomes of another mechanism: Both outcomes are likely to be related to the erosion of the social and environmental and material context. As such, the findings refer to a need to implement psychosocial context-oriented interventions to address the erosion of the context rather than specific mental health interventions.

The objectives of this study were to develop a novel training model for using mass-casualty incident (MCI) scenarios that trained hospital and prehospital staff together using Microsoft Visio, images from Google Earth and icons representing first responders, equipment resources, local hospital emergency department bed capacity, and trauma victims. The authors also tested participants’ knowledge in the areas of communications, incident command systems (ICS), and triage.
Methods
Participants attended Managing Multiple-Casualty Incidents (MCIs), a one-day training which offered pre- and post-tests, two one-hour functional exercises, and four distinct, one-hour didactic instructional periods. Two MCI functional exercises were conducted. The one-hour trainings focused on communications, National Incident Management Systems/Incident Command Systems (NIMS/ICS) and professional roles and responsibilities in NIMS and triage. The trainings were offered throughout communities in western Montana. First response resource inventories and general manpower statistics for fire, police, Emergency Medical Services (EMS), and emergency department hospital bed capacity were determined prior to MCI scenario construction. A test was given prior to and after the training activities.
Results
A total of 175 firefighters, EMS, law enforcement, hospital personnel or other first-responders completed the pre- and post-test. Firefighters produced higher baseline scores than all other disciplines during pre-test analysis. At the end of the training all disciplines demonstrated significantly higher scores on the post-test when compared with their respective baseline averages. Improvements in post-test scores were noted for participants from all disciplines and in all didactic areas: communications, NIMS/ICS, and triage.
Conclusions
Mass-casualty incidents offer significant challenges for prehospital and emergency room workers. Fire, Police and EMS personnel must secure the scene, establish communications, define individuals’ roles and responsibilities, allocate resources, triage patients, and assign transport priorities. After emergency department notification and in advance of arrival, emergency department personnel must assess available physical resources and availability and type of manpower, all while managing patients already under their care. Mass-casualty incident trainings should strengthen the key, individual elements essential to well-coordinated response such as communications, incident management system and triage. The practice scenarios should be matched to the specific resources of the community. The authors also believe that these trainings should be provided with all disciplines represented to eliminate training “silos,” to allow for discussion of overlapping jurisdictional or organizational responsibilities, and to facilitate team building.

Each mass disaster has its own characteristics and will involve a different approach, so the safeguarding and collection of forensic evidence have to be considered as part of the field response procedure. DNA typing has played a more prominent role in the identification of human remains, and particularly so for highly decomposed and fragmented remains. Although the ultimate goal is to obtain the identification, the specific context of each application of human identity testing has its specific problems, ranging from technical approach, through statistical interpretation, to ethical issues. The preparedness plan of the forensic genetics laboratory needs to include policies for family notification, long-term sample storage, and data archiving. For this reason, DNA sample collection and a strategy for DNA-based victim identification needs to be part of the preparedness plan. In this paper, the authors seek to define three of these ethical aspects: (1) the humanitarian importance of identification; (2) resource allocation in the victims’ DNA identification; and (3) the secondary use for research of the samples initially collected for identification purposes. DNA analysis for the purpose of identifying victims of mass disasters has complex implications that demand much more rigorous examination than they have received until now.

Portable suction units used by EMS personnel are utilized infrequently and often are powered by batteries. Lack of use and inspection often results in failure of the device when it is needed. The purpose of this study was to examine the incidence of portable suction unit failure in a rural EMS system and to identify the reasons for failures.
Methods
A convenience sample was obtained through both random inspections by the staff of a regional EMS council and data from twice monthly checks reported by respective EMS agencies following a standard protocol for each unit. A standard protocol was used, including checking the vacuum level on each suction unit and inspecting the tubing, canister, and battery. Each inspector assessed whether the unit was capable of achieving 300 mmHg of suction within four seconds. Also, the unit was inspected for any signs of misalignment or dry rot of the gasket, kinking of suction hose, damage to the suction canister, weak/dead battery, or defective pump. Findings were recorded.
Results
Over a two-year period, 9,631 suction unit inspections were completed. There were 233 failures (2.4%) noted. The majority (126, 54.1%) were due to battery failure. Seventy-three units failed due to other reasons (not recorded, switch failure, battery not seated). Ten inspections failed due to incorrect assembly. Nineteen inspections failed due to defects with the suction canister. Five inspections failed due to kinked/disconnected suction tubing.
Conclusion
Only a relatively small percentage of inspections of suction units revealed failures (4.6% Advanced Life Support, 8.6% Basic Life Support) using the above-stated criteria. However, given the importance of airway management and potential complications associated with airway compromise, including aspiration pneumonia, hypoxia, and hemodynamic instability, this is of concern relative to the morbidity and mortality that could be related to airway failure. Due to the relative infrequency of use and the nature of portable suction units, the potential for lack of maintenance and deficiencies in routine inspection may impact the functional status of these devices in EMS agencies. Clearly, improved documentation of battery installation date, charging in accordance with manufacturer recommendations, and thorough inspection of the portable suction unit in its entirety will ensure readiness of these devices. Additionally, more rigorous documentation and analysis of inspections should be a focus of EMS agencies.

An investment strategist recently published, in the journal Nature, an impassioned plea to all scientists that they must begin to speak out on the resource crisis exacerbated by global warming. In this Editorial response, the author reminds health professionals that they can no longer stay silent and pander to the ignorance of others, and challenges them, along with multidisciplinary partners and stakeholders, to define a strong collaborative and cooperative stance on climate change.

The emergency telephone number 9-1-1 serves as a lifeline to the public during emergencies, and first responders rely on information gathered by 9-1-1 telecommunicators who speak with callers. Timely, accurate information from the telecommunicators is essential for providing appropriate care on scene. Language barriers can hamper these efforts and result in less efficient information exchange. Although 9-1-1 telecommunicators may access over-the-phone interpreter (OPI) services to facilitate communication, managing three-way communication during an emergency is challenging.
Problem
There is little published on the relationship between limited English proficient (LEP) callers and 9-1-1 police telecommunicators, and the role of OPI services during these calls. Further, little is known about effective strategies to manage such calls.
Methods
In King County, Washington, 9-1-1 police telecommunicators were surveyed about their experiences handling LEP calls and managing three-way communication with OPI services. The survey contained 13 multiple-choice and three open-response questions addressing communication strategies, challenges with LEP callers, and three-way communication with OPI services. Goodman-Kruskal Gamma and chi-square tests were conducted with OPI use as the dependent variable. Additional analyses were conducted using stress levels as the dependent variable.
Results
Of 123 respondents, 69 (56.5%) 9-1-1 telecommunicators reported utilizing OPI services at least 75% of the time when receiving a call from an LEP caller. Further, 35 (28.7%) of these telecommunicators reported calls with LEP individuals as more stressful than calls with fluent English speakers. Dispatcher stress level during LEP calls compared with stress during calls with fluent English speakers was positively associated with use of OPI services (P < .01). Further, stress level was also positively associated with telecommunicator difficulties in assessing the situation with respect to officer safety (P < .01). Sixty-three (58.3%) of the telecommunicators described difficulties assessing the situation to determine the appropriate response as the biggest challenge with LEP callers. Additionally, 62 (53%) identified knowing their location in English as information LEP callers need to know prior to calling 9-1-1.
Conclusion
These results highlight intervention opportunities for both 9-1-1 telecommunicators and LEP communities. Together, interventions such as working with LEP communities to educate them on best communication practices during 9-1-1 calls, and with 9-1-1 telecommunicators to help them manage three-way communication and reduce stress associated with concern for officer safety may improve emergency communication during 9-1-1 calls.

The objective of disaster preparedness is to ensure that appropriate systems, procedures, and resources are in place to provide prompt, effective assistance to disaster victims, thus facilitating relief measures and rehabilitation of services. Disaster preparedness efforts include the identification of possible health scenarios based on the probability of hazards and vulnerability of the population as a basis for creating a disaster plan. Exercises that simulate emergency response, involving the health and other sectors, have been suggested as useful tools to test the plans on a regular basis and measure preparedness efforts; the absence of actual testing is likely to negate even the best of abstract plans.
Problem
Exercises and after action reports (AARs) are used to document preparedness activities. However, to date, limited analysis has been performed on what makes an exercise an effective tool to assess public health emergency preparedness (PHEP), and how AARs can be developed and used to support PHEP improvement efforts. The scope of this project was to achieve consensus on: (1) what makes an exercise an effective tool to assess PHEP; and (2) what makes an AAR an effective tool to guide PHEP improvement efforts.
Methods
Sixty-one PHEP experts were convened by the use of Nominal Group Techniques to achieve consensus on a series of characteristics that exercises should have when designed to assess PHEP and on the recommendations for developing high-quality AARs.
Results
The panelists achieved consensus on a list of recommendations to improve the use of exercises and AARs in PHEP improvement efforts. Such recommendations ranged from the characteristics of the exercise audience to the evaluation methodology being used and the characteristics of the produced AAR such as its structure and content.
Conclusions
The characteristics of the exercise audience, scenario and scope are among the most important attributes to the effectiveness of an exercise conducted for PHEP evaluation purposes. The evaluation instruments used to gather observations need an appropriate matching between exercise objectives and the response capabilities tested during the exercise, to build the base for the production of a good AAR. Improvements in the design and creation of exercises and AARs could facilitate better reporting and measurement of preparedness outcomes.
