The Richter Scale measures the magnitude of a seismic occurrence, but it does not feasibly quantify the magnitude of the “disaster” at the point of impact in real humanitarian needs, based on United Nations International Strategy for Disaster Reduction (UNISDR; Geneva, Switzerland) 2009 Disaster Terminology. A Disaster Severity Index (DSI) similar to the Richter Scale and the Mercalli Scale has been formulated; this will quantify needs, holistically and objectively, in the hands of any stakeholders and even across timelines.

An agreed terminology in quantifying “disaster” matters; inconsistency in measuring it by stakeholders posed a challenge globally in formulating legislation and policies responding to it.

A quantitative, mathematical calculation which uses the median score percentage of 100% as a baseline, indicating the ability to cope within the local capacity, was used. Seventeen indicators were selected based on the UNISDR 2009 disaster definition of vulnerability and exposure and holistic approach as a pre-condition. The severity of the disaster is defined as the level of unmet needs. Thirty natural disasters were tested, retrospectively, and non-parametric tests were used to test the correlation of the DSI score against the indicators.

The findings showed that 20 out of 30 natural disasters tested fulfilled the inability to cope, within local capacity in disaster terminology. Non-parametric tests showed that there was a correlation between the 30 DSI scored and the indicators.

By computing a median fit percentage score of 100% as the ability to cope, and the correlation of the 17 indicators, in this DSI Scale, 20 natural disasters fitted into the disaster definition. This DSI will enable humanitarian stakeholders to measure and compare the severity of the disaster objectively, as well as enable future response to be based on needs.

Natural disasters have many effects on vulnerable groups, especially infants and children. Protecting breastfeeding in disasters is important, because artificial feeding puts a lot of risk to the child. In disasters, artificial nutrition is dangerous to children and its supplementation requires special equipment. There is little information on the nutritional status of infants after disasters in Iran.

The purpose of this study was to explore the barriers to appropriate lactation after disasters in Iran.

This was a qualitative study using a content analysis method. A total of 19 midwives with disaster-relief experiences were approached for interview. Data were collected using semi-structured interviews. Data analysis was performed using the Graneheim’s approach.

The categories of maternal factors, neonatal factors, management factors, and context-base factors were extracted from the data.

The challenges of social support, mothers’ self-efficacy, educated staff for disasters, and privacy for breastfeeding can be considered as important barriers to breastfeeding in disasters. Training programs, as well as health system support, can help overcome the breastfeeding barriers in disasters.

Recent natural and infrastructural disasters, such as Hurricanes Sandy (2012) and Katrina (2005) and the Northeastern power outage of 2003, have emphasized the need for hospital staff to be trained in disaster management and response. Even an internal hospital disaster may require the safe and efficient evacuation and transfer of patients with varying medical conditions and complications. A notably susceptible population is renal transplant patients, including those with post-transplant complications.

This descriptive study evaluated staff performance of a vertical evacuation drill of renal transplant patients at State University of New York (SUNY) Downstate Medical Center – University Hospital Brooklyn (UHB; Brooklyn, New York USA).

Thirteen standardized patients, 12 of whom received a renal transplant, with varying medical histories, ambulatory ability, and mental status were vertically evacuated by the transplant staff from the eighth floor to the ambulance entrance on the ground floor. Non-ambulatory patients were transported on portable evacuation sleds.

All patients were evacuated successfully within 3.5 hours. On a post-drill evaluation form, drill participants self-reported largely positive results concerning their own role in the drill and the evacuation drill itself. Drill evaluators observed very different results, including staff reticence, poor training retention, and lack of leadership.

Despite encouraging post-drill evaluation results from the participants, the evacuation drill highlighted several immediate deficiencies. It also demonstrated a significant discrepancy in performance perception between the drill participants and the drill evaluators.

In addition to the traditional logistics role, pharmacists are undertaking important new roles in disasters. Despite this, little is known about the level of acceptance of these activities by other providers.

The aim of this study was to determine the international opinion of disaster and health professionals regarding the emerging roles of pharmacists in disasters.

Delegates at the World Association for Disaster and Emergency Medicine’s (WADEM; Madison, Wisconsin USA) 20th Congress in Toronto, Canada (April 2017) were invited to complete an anonymous survey posing eight questions regarding attitudes towards pharmacists’ roles in disasters. Quantitative data were analyzed using IBM (IBM Corp.; Armonk, New York USA) SPSS statistical software version 23, and qualitative data were manually coded.

Of the 222 surveys handed out, 126 surveys were completed yielding a 56.8% response rate. Of the respondents, 96.8% (122/126) believed pharmacists had a role in disasters additional to logistics. Out of 11 potential roles pharmacists could perform in a disaster, provided on a 5-point Likert scale, eight roles were given a rating of “Agree” or “Strongly Agree” by 72.4% or more of the participants. Lack of understanding of a pharmacist’s roles and capabilities was the highest described barrier to pharmacists’ roles in disaster management.

This multi-disciplinary disaster health “community” agreed pharmacists have roles in disasters in addition to the established role in supply chain logistics. Participants accepted that pharmacists could possibly undertake numerous clinical roles in a disaster. Several barriers were identified that may be preventing pharmacists from being further included in disaster health management planning and response.

Conducted electrical weapons (CEWs), including Thomas A. Swift Electric Rifles (TASERs), are increasingly used by law enforcement officers (LEOs) in the US and world-wide. Little is known about the experience of Emergency Medical Service (EMS) providers with these incidents.

This study describes EMS encounters with documented TASER use and barb removal, characteristics of resulting injuries, and treatment provided.

This retrospective study used five combined, consecutive National Emergency Medical Services Information System (NEMSIS; Salt Lake City, Utah USA) public-release datasets (2011-2015). All EMS activations with documented TASER barb removal were included. Descriptive analyses were carried out.

The study included 648 EMS activations with documented TASER barb removal, yielding a prevalence rate of 4.55 per 1,000,000 EMS activations. Patients had a mean age of 35.9 years (SD=18.2). The majority were males (80.2%) and mainly white (71.3%). Included EMS activations were mostly in urban or suburban areas (78.3%). Over one-half received Advanced Life Support (ALS)-level of service (58.2%). The most common chief complaint reported by dispatch were burns (29.9%), followed by traumatic injury (16.1%). Patients had pain (45.6%) or wound (17.2%) as a primary symptom, with most having possible injury (77.8%). Reported causes of injury were mainly fire and flames (29.8%) or excessive heat (16.7%). The provider’s primary impressions were traumatic injury (66.3%) and behavioral/psychiatric disorder (16.8%). Only one cardiac arrest (0.2%) was reported. Over one-half of activations resulted in patient transports (56.3%), mainly to a hospital (91.2%). These encounters required routine EMS care (procedures and medications). An increase in the prevalence of EMS activations with documented TASER barb removal over the study period was not significant (P=.27).

At present, EMS activations with documented TASER barb removal are rare. Routine care by EMS is expected, and life-threatening emergencies are not common. All EMS providers should be familiar with local policies and procedures related to TASER use and barb removal.

Frequent calls to 911 and requests for emergency services by individuals place a costly burden on emergency response systems and emergency departments (EDs) in the United States. Many of the calls by these individuals are non-emergent exacerbations of chronic conditions and could be treated more effectively and cost efficiently through another health care service. Mobile integrated community health (MICH) programs present a possible partial solution to the over-utilization of emergency services by addressing factors which contribute to a patient’s likelihood of frequent Emergency Medical Services (EMS) use. To provide effective care to eligible individuals, MICH providers must have a working understanding of the common conditions they will encounter.

The purpose of this descriptive study was to evaluate the diagnosis prevalence and comorbidity among participants in the Queen Anne’s County (Maryland USA) MICH Program. This fundamental knowledge of the most common medical conditions within the MICH Program will inform future mobile integrated health programs and providers.

This study examined preliminary data from the MICH Program, as well as 2017 Maryland census data. It involved secondary analysis of de-identified patient records and descriptive statistical analysis of the disease prevalence, degree of comorbidity, insurance coverage, and demographic characteristics among 97 program participants. Diagnoses were grouped by their ICD-9 classification codes to determine the most common categories of medical conditions. Multiple linear regression models and chi-squared tests were used to assess the association between age, sex, race, ICD-9 diagnosis groups, and comorbidity among program enrollees.

Results indicated the most prevalent diagnoses included hypertension, high cholesterol, esophageal reflux, and diabetes mellitus. Additionally, 94.85% of MICH patients were comorbid; the number of comorbidities per patient ranged from one to 13 conditions, with a mean of 5.88 diagnoses per patient (SD=2.74).

Overall, patients in the MICH Program are decidedly medically complex and may be well-suited to additional community intervention to better manage their many conditions. The potential for MICH programs to simultaneously improve patient outcomes and reduce health care costs by expanding into larger public health and addressing the needs of the most vulnerable citizens warrants further study.

In the years following the September 11, 2001 terrorist attacks in New York City (New York USA), otherwise known as 9/11, first responders began experiencing a range of health and psychosocial impacts. Publications documenting these largely focus on firefighters. This research explores paramedic and emergency medical technician (EMT) reflections on the long-term impact of responding to the 9/11 terrorist attacks.

Qualitative methods were used to conduct interviews with 54 paramedics and EMTs on the 15-year anniversary of 9/11.

Research participants reported a range of long-term psychosocial issues including posttraumatic stress disorder (PTSD), anxiety, depression, insomnia, relationship breakdowns and impact on family support systems, and addictive and risk-taking behaviors. Ongoing physical health issues included respiratory disorders, eye problems, and cancers.

These findings will go some way to filling the current gap in the 9/11 evidence-base regarding the understanding of the long-term impact on paramedics and EMTs. The testimony of this qualitative research is to ensure that an important voice is not lost, and that the deeply personal and richly descriptive experiences of the 9/11 paramedics and EMTs are not forgotten.

Mass gatherings such as marathons are increasingly frequent. During mass gatherings, the provision of timely access to health care services is required for the mass-gathering population, as well as for the local community. However, the nature and impact of health care provision during sporting mass gatherings is not well-understood.

The aim of this study was to describe the structures and processes developed for an emergency health team to operate an in-event, acute health care facility during one of the largest mass-sporting participation events in the southern hemisphere, the Gold Coast Marathon (Queensland, Australia).

A pragmatic, qualitative methodology was used to describe the structures and processes required to operate an in-event, acute health care facility providing services for marathon runners and spectators. Content analysis from 12 semi-structured interviews with emergency department (ED) clinical staff working during the two-day event was undertaken in 2016.

Important structural elements of the in-event health care facility included: physical spaces, such as the clinical zones in the marathon health tent and surrounding area, and access and egress points; and resources such as bilingual staff, senior medical staff, and equipment such as electrocardiograms (ECGs) and intravenous fluids. Process elements of the in-event health care facility included clear communication pathways, as well as inter-professional care coordination and engagement involving shared knowledge of and access to resources, and distinct but overlapping clinical scope between nurses and doctors. This was seen to be critical for timely care provision and appropriate case management. Staff reported many perceived benefits and opportunities of in-event health care delivery, including ED avoidance and disaster training.

This in-event model of emergency care delivery, established in an out-of-hospital location, enabled the delivery of acute health care that could be clearly described and defined. Staff reported satisfaction with their ability to provide a meaningful contribution to hospital avoidance and to the local community. With the number of sporting mass gatherings increasing, this temporary, in-event model of health care provision is one option for event and health care planners to consider.

Music festivals are globally attended events that bring together performers and fans for a defined period of time. These festivals often have on-site medical care to help reduce the impact on local health care systems. Historically, the literature suggests that patient transfers off-site are frequently related to complications of substance use. However, there is a gap in understanding why patients are transferred to hospital when an on-site medical team, capable of providing first aid services blended with a higher level of care (HLC) team, is present.

The purpose of this study is to better understand patterns of injuries and illnesses that necessitate transfer when physician-led HLC teams are accessible on-site.

This is a prospective, descriptive case series analyzing patient encounter documentation from four large-scale, North American, multi-day music festivals.

On-site medical teams that included HLC team members were present for the duration of each festival, so every team was able to “treat and release” when clinically appropriate. Over the course of the combined 34 event days, there were 10,406 patient encounters resulting in 156 individuals being transferred off-site for assessment, diagnostic testing, and/or treatment. A minority of patients seen were transferred off-site (1.5%). The patient presentation rate (PPR) was 16.5/1,000. The ambulance transfer rate (ATR) was 0.12/1,000 attendees, whereas the total transfer-to-hospital rate (TTHR), when factoring in non-ambulance transport, was 0.25/1,000. In contrast to existing literature on transfers from music festivals, the most common reason for transfer off-site was for musculo-skeletal (MSK) injuries (53.8%) that required imaging.

The presence of on-site HLC teams impacted the case mix of patients transferred to hospital, and may reduce the number of transfers for intoxication. Confounding preconceptions, patients in the present study were transferred largely for injuries that required specialized imaging and testing that could not be performed in an out-of-hospital setting. These results suggest that a better understanding of the specific effects on-site HLC teams have on avoiding off-site transfers will aid in improving planning for music festivals. The findings also identify areas for further improvement in on-site care, such as integrated on-site radiology, which could potentially further reduce the impact of music festivals on local health services. The role of non-emergency transport vehicles (NETVs) deserves further attention.

The aim of this study was to examine the extent to which an exposure to disaster is associated with change in health behaviors.

Federal disaster declarations were matched at the county-level to self-reported behaviors for participants in the Health and Retirement Study (HRS), 2000-2014. Multivariable logistic regression was used to evaluate the relationship between disaster and change in physical activity, body mass index (BMI), and cigarette smoking.

The sample included 20,671 individuals and 59,450 interviews; 1,451 unique disasters were declared in counties in which HRS respondents lived during the study period. Exposure to disaster was significantly associated with weight gain (unadjusted RRR=1.19; 95% CI, 1.11-1.27; adjusted RRR=1.21; 95% CI, 1.13-1.30). Vigorous physical activity was significantly lower among those who had experienced a disaster compared to those who had not (unadjusted OR=0.89; 95% CI, 0.84-0.95; adjusted OR=0.84; 95% CI, 0.79-0.89). No significant difference in cigarette smoking was found.

This study found an increase in weight gain and decrease in physical activity among older adults after disaster exposure. Adverse health behaviors such as these can contribute to functional decline among older adults.

There is insufficient research on medical care at mass-gathering events (MGEs) on college and university campuses. Fun Day is an annual celebratory day held at Skidmore College (Saratoga Springs, New York USA), a small liberal arts college in the Northeastern United States. Fun Day is focused around an outdoor music festival; students also congregate and celebrate throughout the surrounding campus. To improve care and alleviate strain on local resources, a model was developed for the provision of emergency care by a collegiate-based, volunteer first-response service – Skidmore College Emergency Medical Services (EMS) – in coordination with a contracted, private ambulance service.

The aims of this study were to: (1) analyze medical usage rates and case mixes at Fun Day over a four-year period, and to (2) describe the collegiate-based first response model for MGEs.

Data were collected retrospectively from event staff, college administrators, and Skidmore College EMS on event-related variables, patient encounters, and medical operations at Fun Day over a four-year period (2014-2017).

Annual attendance at the music festival was estimated at 2,000 individuals. Over four years, 54 patients received emergency medical care on campus on Fun Day, and 18 (33.3%) were transported to the emergency department. On-site contracted ambulances transported 77.8% of patients who were transported to the emergency department; mutual aid was requested for the other 22.2% of transports. The mean (SD) patient presentation rate (PPR) was 7.0 (SD = 1.0) per 1,000 attendees. The mean (SD) transport-to-hospital rate (TTHR) was 2.0 (SD = 1.0) per 1,000 attendees. Thirty (55.6%) patients presented with intoxication, seven (13.0%) with laceration(s), and five (9.3%) with head trauma as the primary concern. Medical command was established by volunteer undergraduate students. Up to 16 volunteer student first responders (including emergency medical technicians [EMTs]) were stationed on campus, in addition to two contracted ambulances at the Basic Life Support (BLS) and Advanced Life Support (ALS) levels. Operational strategies included: mobile first response crews, redundant communication systems, preventative education, and harm reduction.

High medical usage rates were observed, primarily due to alcohol/illicit substance use and traumatic injuries. The provision of emergency care by a collegiate-based first response service in coordination with a contracted, private ambulance agency serves as an innovative model for mass-gathering medical care on college and university campuses.

In the prehospital setting, many providers advocate for video laryngoscopy as the initial method of intubation to improve the likelihood of a successful first attempt. However, bright ambient light can worsen visualization of the video laryngoscope liquid crystal display (LCD).

A patient involved in a motor vehicle accident was evaluated by an Emergency Medical Services (EMS) crew. Initial endotracheal intubation attempt using video laryngoscopy was aborted after the patient desaturated. The primary reason for the failure was poor visualization of the video laryngoscope LCD, despite attempts to block direct sunlight. Debriefing revealed that the intubating provider was wearing polarized sunglasses.

Because LCDs emit polarized light, use of polarized sunglasses may cause the display to appear dark. Thus, the purpose of this Case Report is to raise awareness of a potential safety issue that is likely under-recognized by prehospital providers but can be easily avoided.
