Emergency medical care in Pakistan has not been a priority of medical education and training because of the country's need to address its lack of primary care. Resources and trained personnel are scarce. Despite these challenges, the value of emergency medical care is gaining attention. The objective of this study was to explore the breadth of Emergency Medicine training in Pakistan through an analysis of an Emergency Medicine residency in a teaching hospital. The Aga Khan University Hospital in Karachi is a teaching institution with the only Emergency Medicine residency program in the region. It was started in 2000, led by US-trained physicians, and it laid the foundation for Emergency Medicine in the country.

The study was conducted over a four-week period in January of 2009. Data collection consisted of three components: (1) a survey of the Emergency Department and hospital services; (2) a survey of the Emergency Medicine training curriculum; and (3) a retrospective chart review of every tenth patient seen in the Aga Khan Emergency Department from December 1-14, 2008.

The training program is similar to that of the US models. Of the 153 patients selected for the chart review, the majority presented with GI complaints. Of these, 51 (33%) were admitted to the hospital; 20% (n = 15) left against medical advice; the remaining 57% (n = 87) were discharged.

The hospital admitted patients with complaints that were expected in the region. Although Aga Khan University Hospital is a pioneer in establishing Emergency Medicine as an official medical discipline in the region, the hospital's obstetrics and gynecology, trauma, toxicology and prehospital services training do not meet current curriculum standards set forth by the Society of Academic Emergency Medicine and the Council of Emergency Medicine Residency Directors. Nevertheless, the review provides a snapshot of the development of Emergency Medical Services in a developing nation. This information may assist other nations that are interested in developing such programs.

The Comprehensive Framework for Disaster Evaluation Typologies, developed in 2017 (CFDET 2017), aims to unify and facilitate agreement regarding the identification, structure, and relationships between various evaluation typologies found in the disaster setting. A peer-reviewed validation process sought input from international experts in the fields of disaster medicine, disaster/emergency management, humanitarian/development, and evaluation. This paper discusses the validation process, its results, and outcomes.

Previous frameworks, identified in the literature, lack validation and consistent terminology. To gain credibility and utility, this unique framework needed to be validated by international experts in the disaster setting.

A mixed methods approach was designed to validate the framework. An initial iterative process informed an online survey which used a combination of a five-point Likert scale and open-ended questions. Pre-determined consensus thresholds, informed by a targeted literature review, provided the validation criteria.

A sample of 33 experts from 11 countries responded to the validation process. Quantitative measures largely supported the elements and relationships of the framework, and strongly supported its value and usefulness for supporting, promoting, and undertaking evaluations, as well as its usefulness for teaching evaluation in the disaster setting. Qualitative input suggested opportunities to strengthen and enhance the framework. There were limited responses to better understand the barriers and enablers of undertaking disaster evaluations. A potential for self-selection bias of respondents may be a limitation of this study. The attainment of high consensus thresholds, however, provides confidence in the validity of the results.

For the first time, a framework of this nature has undergone a rigorous validation process by experts in three related disciplines at an international level. The modified framework, CFDET 2018, provides a unifying framework within which existing evaluation typologies can be structured. It gives evaluators confidence to choose an appropriate strategy for their particular evaluation in the disaster setting and facilitates consistency in reporting across the different phases of a disaster to better understand the process, outcomes, and impacts of the efficacy and efficiency of interventions. Future research could create a series of toolkits to support improved disaster evaluation processes and to evaluate the utility of the framework in the real-world setting.

Official counts of deaths attributed to disasters are often under-reported, thus adversely affecting public health messaging designed to prevent further mortality. During the Oklahoma (USA) May 2013 tornadoes, Oklahoma State Health Department Division of Vital Records (VR; Oklahoma City, Oklahoma USA) piloted a flagging procedure to track tornado-attributed deaths within its Electronic Death Registration System (EDRS). To determine if the EDRS was capturing all tornado-attributed deaths, the Centers for Disease Control and Prevention (CDC; Atlanta, Georgia USA) evaluated three event fatality markers (EFM), which are used to collate information about deaths for immediate response and retrospective research efforts.

Oklahoma identified 48 tornado-attributed deaths through a retrospective review of hospital morbidity and mortality records. The Centers for Disease Control and Prevention (CDC; Atlanta, Georgia USA) analyzed the sensitivity, timeliness, and validity for three EFMs, which included: (1) a tornado-specific flag on the death record; (2) a tornado-related term in the death certificate; and (3) X37, the International Classification of Diseases, 10th Revision (ICD-10) code in the death record for Victim of a Cataclysmic Storm, which includes tornadoes.

The flag was the most sensitive EFM (89.6%; 43/48), followed by the tornado term (75.0%; 36/48), and the X37 code (56.2%; 27/48). The most-timely EFM was the flag, which took 2.0 median days to report (range 0-10 days), followed by the tornado term (median 3.5 days; range 1-21), and the X37 code (median >10 days; range 2-122). Over one-half (52.1%; 25/48) of the tornado-attributed deaths were missing at least one EFM. Twenty-six percent (11/43) of flagged records had no tornado term, and 44.1% (19/43) had no X37 code. Eleven percent (4/36) of records with a tornado term did not have a flag.

The tornado-specific flag was the most sensitive and timely EFM. Using the flag to collate death records and identify additional deaths without the tornado term and X37 code may improve immediate response and retrospective investigations. Moreover, each of the EFMs can serve as quality controls for the others to maximize capture of all disaster-attributed deaths from vital statistics records in the EDRS.

Emergency physicians are using bolus-dose vasopressors to temporize hypotensive patients until more definitive blood pressure support can be established. Despite a paucity of clinical outcome data, emergency department applications are expanding into the prehospital setting. This series presents two cases of field expedient vasopressor use by emergency medicine providers for preflight stabilization during aeromedical evacuation to a hospital ship as part of the United States Navy disaster response in Puerto Rico. A critical approach and review of the literature are discussed.

Two critically ill patients were managed in an austere environment as a result of the devastation from Hurricane Maria (Yabucoa, Puerto Rico; 2017). They both exhibited signs of respiratory distress, hemodynamic instability, and distributive shock requiring definitive airway management and hemodynamic support prior to aeromedical evacuation.

The novel use of field expedient vasopressors prior to induction for rapid sequence intubation was successfully and safely employed in both cases. Both patients had multiple risk factors for peri-induction cardiac arrest given their presenting hemodynamics. Despite their illness severity, both patients were induced, transported, and ultimately admitted to the intensive care unit (ICU) in stable condition following administration of the field expedient vasopressors.

Field expedient vasopressors were safely and effectively employed in an austere field environment during a disaster response. This case series contributes to the growing body of literature of safe bolus-dose vasopressor use by emergency physicians to temporize hypotensive patients in resource-constrained situations.

Paramedics accurately estimate the closest trauma hospital for ground transport.

Ground ambulance scene transports of trauma system patients to six participating trauma hospitals in Multnomah County, Oregon from 1 January 1986 to 1 January 1987 were studied. Transports involving multiple patients or pediatric patients were excluded.

A retrospective analysis was performed on consecutive patient transports to be taken to the closest trauma hospital as required by protocol. The availability of each hospital to receive trauma patients was monitored continuously by a central communications facility. Paramedics were provided hospital availability data at the time of patient system entry. When several hospitals were available, the paramedics were required by protocol to select the “closest” hospital. Subsequently, the vector distance from the trauma site to each of the available hospitals was measured using a grid map. This method was validated by odometer measurement (r2 = 0.924). Chisquare analysis was used to analyze hospital bypasses to specific hospitals.

Of the 1193 eligible patients entered into the trauma system, 160 (13%; 95% CI = 11–15%) transports bypassed the closest available hospital for a receiving hospital ≥1 mile more distant. There were 11 (1%; 0–2%) patients transported to a hospital more than five miles more distant. Of the 132 patients with a trauma score (TS) <12, 15 (11%; 6–18%) were taken to a hospital one mile or further beyond the closest hospital. None (0%; 0–2%) were transported more than five miles past the closest hospital. Of the six hospitals, three were bypassed more than one mile significantly more often then they received bypass patients. One hospital received such patients four times more than it was bypassed (p <.001).

While paramedics generally can identify the closest hospital for trauma patient transport, some systematic hospital bypass errors occur. If a community wants assurance of an equitable patient distribution among participating trauma hospitals and assignment of the closest geographic hospital for injured patients, then map vector distance determination to identify the closest available hospital should supplement paramedic dispatching.

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 prehospital 12-lead electrocardiogram (ECG) has become a standard of care. For the prehospital 12-lead ECG to be useful clinically, however, cardiologists and emergency physicians (EP) must view the test as useful. This study measured physician attitudes about the prehospital 12-lead ECG.

This study tested the hypothesis that physicians had “no opinion” regarding the prehospital 12-lead ECG.

An anonymous survey was conducted to measure EP and cardiologist attitudes toward prehospital 12-lead ECGs. Hypothesis tests against “no opinion” (VAS = 50 mm) were made with 95% confidence intervals (CIs), and intergroup comparisons were made with the Student-t-test.

Seventy-one of 87 (81.6%) surveys were returned. Twenty-five (67.6%) cardiologists responded and 45 (90%) EPs responded. Both groups of physicians viewed prehospital 12-lead ECGs as beneficial (mean = 69 mm; 95% CI = 65–74mm). All physicians perceived that ECGs positively influence preparation of staff (mean = 63 mm; 95% CI = 60–72mm) and that ECGs transmitted to hospitals would be beneficial (mean = 66 mm; 95% CI = 60–72mm). Cardiologists had more favorable opinions than did EPs. The ability of paramedics to interpret ECGs was not seen as important (mean = 50 mm; 95% CI = 43–56mm). The justifiable increase in field time was perceived to be 3.2 minutes (95% CI = 2.7–3.8 minutes), with 23 (32.8%) preferring that it be done on scene, 46 (65.7%) during transport, and one (1.4%) not at all.

Prehospital 12-lead ECGs generally are perceived as worthwhile by cardiologists and EPs. Cardiologists have a higher opinion of the value and utility of field ECGs. Since the reduction in mortality from the 12-lead ECG is small, it is likely that positive physician attitudes are attributable to other factors.
