July 2007 brought unprecedented levels of flooding to the United Kingdom. Health and financial implications were vast and still are emerging. Hydrological disasters will increase in frequency. Therefore, individual preparedness is paramount, as it may mitigate some of the devastating impacts of flooding. Literature on individual preparedness for flooding is scarce, so it is key that current levels of awareness, information gathering, and protective behaviors are investigated. It also is not clear whether being in a high-risk area or having recent exposure to flooding are motivational factors for preparedness.

The objectives of this study were to: (1) ascertain whether prior experience with flooding is a strong motivational factor for preparedness for future flooding episodes; and (2) assess preparedness in populations at high risk for flooding.

A prospective questionnaire survey was sent to individuals living in two towns in the United Kingdom, Monmouth and Tewkesbury. Both towns are deemed to be at significant risk for flooding, and Tewkesbury was severely affected by the July 2007 flooding disaster. Data were obtained from these two populations and analyzed.

A total of 125 responses (of 200) were returned, and demographic data indicated no major differences between the two populations. The number of protective behaviors was higher from participants from Tewksbury (flood risk and exposure; p = 0.004). Participants from Tewkesbury were more likely to be aware of living in a flood-risk area and of the emergency systems present in the area, and feel prepared for future episodes of major flooding (p = 0.03, p = 0.005).

Awareness of living in a flood risk-area increased the likelihood of being knowledgeable about emergency systems and adopting protective behaviors (p = 0.0053, p = 0.043). However, feeling prepared for future episodes of flooding was not associated with a strong increase in knowledge gained to prepare for flooding or having an increased number of protective behaviors.

Awareness of being at-risk for flooding is vital for self-protective behavior. Both awareness of risk and recent exposure are motivational for flood preparedness. Recent exposure to flooding increases awareness, but it is unknown how long this effect will last. Recent exposure increases the preparedness of individuals for major flooding 18 months after major flooding and, if it continues, will help mitigate the devastating health, financial, and social effects of major flooding.

The H1N1 influenza virus has been described by the World Health Organization (WHO) and the media as a disease that could rival the 1918 Spanish Influenza epidemic in deaths. During the spring of 2009, emergency departments across the world saw a spike in the number of influenza cases and by June 2009, the WHO had declared H1N1 a pandemic. In order to prevent emergency department staff from becoming ill and to provide upto-date medical care to patients, information had to be disseminated quickly to emergency department staff.

An anonymous Internet survey was utilized to query emergency department staff regarding communication methods and overall attitudes regarding safety and treatment during the spring of 2009.

The majority of emergency department staff (263; 88.3%) used multiple sources to obtain information about the H1N1 virus. There were 258 respondents (88.9%) that felt that the hospital was supplying them with the necessary information to protect themselves and their families and 280 (98.5%) felt confident that their emergency department was treating patients by the government-recommended guidelines. Statistically significant differences were noted in communication patterns between direct and indirect patient care providers.

In general, H1N1 communication to emergency department staff was perceived as good during the initial H1N1 outbreak. However, because of the limitations associated with an online survey, these results do not allow for generalization to the total emergency department staff population. Hospital administrators may need to consider the differences in communication preferences of direct patient care providers and indirect patient care providers when distributing important information to emergency department staff during crisis and emergency situations.

Falls are one of the most common types of complaints received by 9-1-1 emergency medical dispatch centers. They can be accidental or may be caused by underlying medical problems. Though not alert” falls patients with severe outcomes mostly are “hot” transported to the hospital, some of these cases may be due to other acute medical events (cardiac, respiratory, circulatory, or neurological), which may not always be apparent to the emergency medical dispatcher (EMD) during call processing.

The objective of this study was to characterize the risk of cardiac arrest and “hot-transport” outcomes in patients with “not alert” condition, within the Medical Priority Dispatch System (MPDS®) Falls protocol descriptors.

This retrospective study used 129 months of de-identified, aggregate, dispatch datasets from three US emergency communication centers. The communication centers used the Medical Priority Dispatch System version 11.3–OMEGA type (released in 2006) to interrogate Emergency Medical System callers, select dispatch codes assigned to various response configurations, and provide pre-arrival instructions. The distribution of cases and percentages of cardiac arrest and hot-transport outcomes, categorized by MPDS® code, was profiled. Assessment of the association between MPDS® Delta-level 3 (D-3) “not alert” condition and cardiac arrest and hot-transport outcomes then followed.

Overall, patients within the D-3 and D-2 “long fall” conditions had the highest proportions (compared to the other determinants in the “falls” protocol) of cardiac arrest and hot-transport outcomes, respectively. “Not alert” condition was associated significantly with cardiac arrest and hot-transport outcomes (p < 0.001).

The “not alert” determinant within the MPDS® “fall” protocol was associated significantly with severe outcomes for short falls (<6 feet; 2 meters) and ground-level falls. As reported to 9-1-1, the complaint of a “fall” may include the presence of underlying conditions that go beyond the obvious traumatic injuries caused by the fall itself.

The Medical Priority Dispatch System (MPDS) is an emergency medical dispatch system widely used to prioritize 9-1-1 calls and optimize resource allocation. This study evaluates whether the assigned priority predicts a Delphi process-derived level of prehospital intervention in each emergency medical dispatch category.

All patients given a MPDS priority in a suburban California county from 2004–2006 were included. A Delphi process of emergency medical services (EMS) professionals in another system developed the following categories of prehospital treatment representing increasing acuity, which were adapted for this study: advanced life support (ALS) intervention, ALS–Stat, and ALS–Critical. The sensitivities and specificities of MPDS priority for level of prehospital intervention were determined for each MPDS category.

A total of 65,268 patients met inclusion criteria, representing 61% of EMS calls during the study period. The overall sensitivities of high-priority dispatch codes for ALS, ALS-Stat, and ALS-Critical interventions were 83% (95% confidence interval 83–84%), 83% (82–84%), and 94% (92–96%). Overall specificities were: ALS, 32% (31–32%); ALS-Stat, 31% (30–31%); and ALS-Critical 28% (28–29%). Compared to calls assigned to a low priority, calls with high-priority dispatch codes were more likely to receive ALS interventions by 22%, ALS-Stat by 20%, and ALS-Critical by 32%. A low priority dispatch code decreased the likelihood of ALS interventions by 48%, ALS-Stat by 45%, and ALS-Critical by 80%. Among high-priority dispatch codes, the rates of interventions were: ALS 26%, ALS-Stat 22%, and ALS-Critical 1.5%, all of which were significantly greater than low-priority calls (p <0.05) [ALS 13%, ALS-Stat 11%, and ALS-Critical 0.2%]. Major MPDS were categories with high sensitivities (>95%) for ALS interventions included breathing problems, cardiac or respiratory arrest/death, chest pain, stroke, and unconscious/fainting; these categories had an average specificity of 3%. Medical Priority Dispatch System categories such as back pain, unknown problem, and traumatic injury had sensitivities for ALS interventions <15%.

The MPDS is moderately sensitive for the Delphi process derived ALS, ALS-Stat, and ALS-Critical intervention levels, but non-specific. A low MPDS priority is predictive of no prehospital intervention. A high priority, however, is of little predictive value for ALS, ALS-Stat, or ALSCritical interventions.

Attendance at UK emergency departments is rising steadily despite the proliferation of alternative unscheduled care providers. Evidence is mixed on the willingness of emergency medical services (EMS) providers to decline to transport patients and the safety of incorporating such an option into EMS provision. Physiologically based Early Warning Scores are in use in many hospitals and emergency departments, but not yet have been proven to be of benefit in the prehospital arena.

The use of a physiological-social scoring system could safely identify patients calling EMS who might be diverted from the emergency department to an alternative, unscheduled, care provider.

This was a retrospective, cohort study of patients with a presenting complaint of “shortness of breath” or “difficulty breathing” transported to the emergency department by EMS. Retrospective calculation of a physiologicalsocial score (PMEWS) based on first recorded data from EMS records was performed. Outcome measures of hospital admission and need for physiologically stabilizing treatment in the emergency department also were performed.

A total of 215 records were analyzed. One hundred thirty-nine (65%) patients were admitted from the emergency department or received physiologically stabilizing treatment in the emergency department. Area Under the Receiver Operating Characteristic Curve (AUROC) for hospital admission was 0.697 and for admission or physiologically stabilizing treatment was 0.710. No patient scoring <2 was admitted or received stabilizing treatment.

Despite significant over-triage, this system could have diverted 79 patients safely from the emergency department to alternative, unscheduled, care providers.

Seattle-King County (SKC) Washington is at risk for regional disasters, especially earthquakes. Of 1.8 million residents, >400,000 (22%) are children, a proportion similar to that of the population of the State of Washington (24%) and of the United States (24%). The county's large area of 2,134 square miles (5,527 km2) is connected through major transportation routes that cross numerous waterways; sub-county zones may become isolated in the wake of a major earthquake. Therefore, each of SKC's three sub-county emergency response zones must have ample pediatric medical response capabilities. To date, total quantities and distribution of crucial hospital resources (available in SKC) to manage pediatric victims of a medical disaster are unknown. This study assessed whether geographical distribution of hospital pediatric resources corresponds to the pediatric population distribution in SKC.

Surveys were delivered electronically to all eight acute care hospitals in SKC that admit pediatric patients. Quantities and categories of pediatric resources, including inpatient treatment space, staff, and equipment, were queried and verified via site visits.

Within the seven responding hospitals of eight queried, the following were identified: 477 formal pediatric bed spaces (pediatric intensive care unit, neo-natal intensive care unit, general wards, and emergency department), 43 informal pediatric bed spaces (operating room and post-anesthesia care unit), 1,217 pediatric nurses, 554 pediatric physicians, and 252 infant/pediatric-adaptable ventilators. The City of Seattle emergency response zone contains 82.1% of bed spaces, 83.5% of nurses, and 95.8% of physicians, yet only 22.8% of all SKC children live in that zone.

The majority of hospital pediatric resources are located in the SKC sub-region with the fewest children. These resources are potentially inaccessible and unable to be redistributed by ground transportation in the event of a significant regional disaster. Future planning for pediatric care in the event of a medical disaster in SKC must address this vulnerability.

The objective of this study was to evaluate the time saved by usage of lights and siren (L&S) during emergency medical transport and measure the total number of time-critical hospital interventions gained by this time difference.

A retrospective study was performed of all advanced life support (ALS) transports using lights and siren to this university emergency department during a three-week period. Consecutive times were measured for 112 transports and compared with measured transport times for a personal vehicle traveling the same day of the week and time of day without lights and siren. The time-critical hospital interventions are defined as procedures or treatments that could not be performed in the prehospital setting requiring a physician. The project assessed whether the patients received the hospital interventions within the average time saved using lights and siren transport.

The average difference in time with versus without L&S was -2.62 minutes (95% CI: -2.60− -2.63, paired t-test p <0.0001). The average transport time with L&S was 14.5 ±7.9 minutes (min) (1 standard deviation/minute (min), range = 1–36 min.). The average transport time without L&S was 17.1 ±8.3 min (range = 1−40 min). Of the 112 charts evaluated, five patients (4.5%) received time-critical hospital interventions. No patients received time-critical interventions within the time saved by utilizing lights and siren. Longer distances did not result in time saved with lights and siren.

Limiting lights and siren use to the patients requiring hospital interventions will decrease the risks of injury and death, while adding the benefit of time saved in these critical patients.

A rapid sequence intubation (RSI) method was introduced to a university-based emergency medical services (EMS) system. This is a report of the initial experience with the first 50 patients in a unique, two-tiered, two-advanced life support (ALS) providers system.

The data were evaluated prospectively after an extensive RSI training period, consisting of didactic information and skills performance. Fifty consecutive patient records that documented the procedure were abstracted. Data abstracted included end-tidal CO2, heart rate, blood pressure, and pulse oximetry at various time intervals. Intubation success rates and number of attempts were documented. The consistency of proper documentation also was noted on patient care records.

No differences were noted in heart rate prior to RSI and one and five minutes after the RSI procedure was begun. No differences in blood pressure at one and five minutes were noted. Statistically significant improvements were found in pulse oximetry comparing prior to RSI and one minute after (p < 0.001; 95% CI = 3.15–11.41) as well as prior to RSI and five minutes after RSI was started (p < 0.0002; 95% CI = 4.60–13.33). No differences were observed in end-tidal CO2 at one and five minutes. Overall intubation success rate was 96%, with 82% on first attempt and 92% on two or less attempts. Documentation for individual vitals was consistently <75%.

Patients had no significant worsening of vital signs during the RSI procedure and mild improvement in pulse oximetry. Intubation success rates were consistent with national averages. Proper documentation was lacking in more than one quarter of the charts. These data add to a body of literature that raises further concerns regarding prehospital RSI.

In the absence of other data, military Tactical Combat Casualty Care (TCCC) precepts are increasingly being adapted to law enforcement needs. The purpose of this study is to better describe the nature of potentially preventable law enforcement Line-of-Duty Deaths (LODDs) occurring as a result of felonious assaults.

A retrospective analysis was performed of open source data available through the US Federal Bureau of Investigation (FBI) Uniform Crime Reporting (UCR) Law Enforcement Officers Killed and Assaulted (LEOKA) program for the years 1998–2007 inclusive.

After applying exclusion criteria, 341 victim officers were included in the study. The most common cause of death was head trauma (n = 198), followed by chest trauma (n = 90). There were 123 victim officers that suffered potentially preventable deaths; the majority of these injuries involved the chest. Over the 10-year study period, only two officers (0.6%) died from isolated extremity hemorrhage.

The current emphasis of TCCC on control of exsanguinating extremity hemorrhage may not meet the needs of law enforcement personnel in an environment with expedited access to well-developed trauma systems. Further study is needed to better examine the causes of preventable deaths in law enforcement officers, as well as the most appropriate law enforcement tactical medical skill set and treatment priorities.

Four weeks after the earthquake in Kashmir, Pakistan, multi-disciplinary surgical teams were organized within the United Kingdom to help treat disaster victims who had been transferred to Rawalpindi. The work of these teams between 05-17 November 2005 is reviewed, and experiences and lessons learned are presented.

Two self-sufficient teams consisting of orthopedic, plastic surgical, anesthetic, and theatre staff were deployed consecutively over a two-week period. A trauma unit was set up in a donated ward within a private ophthalmological hospital in Rawalpindi.

Seventy-eight patients with a mean age of 23 years were treated: more than half (40) were <16 years of age. Fifty-two patients only had lower limb injuries, 18 upper limb injuries, and eight combined lower and upper limb. The most common types of injuries were: (1) tibial fractures (n = 24), with the majority being open grade 3B injuries (n = 22); (2) femoral fractures (n = 11); and (3) forearm fractures (n = 9). Almost half (n = 34) of the fractures were open injuries requiring soft tissue cover.

Over 12 days, 293 operations were performed (average 24.4 per day). A total of 202 examinations under anesthesia, washouts, and debridements were performed. The majority of wounds required multiple washouts prior to definitive procedures. Thirty-four definitive orthopedic procedures (fixations) and 57 definitive plastic procedures were performed. Definitive orthopedic procedures included 15 circular frame fixations of long bones, nine of which required acute shortening and five open reduction and internal fixation of long bones. Definitive plastic procedures included 21 skin grafts, four amputations, 11 revisions of amputations, 20 regional flaps, and one free flap.

A joint ortho-plastic approach was key to the treatment of the spectrum of injuries encountered. Only four patients required fresh amputations. Twenty patients may have required amputation without the use of ring fixators and soft tissue reconstruction. Having self-sufficient teams along with their own equipment and supplies also was mandatory in order not to put further demand on already scarce resources. However, mobilizing such teams logistically was difficult, and therefore, an organization consisting of willing volunteers for future efforts has been established.
