To determine the effect of a State of Emergency (SOE) on penetrating injuries at the main trauma center in Trinidad and Tobago.

Emergency room registers were accessed in order to identify all patients treated for penetrating injuries from July 1, 2010 through December 30, 2012. This study period was chosen to include injuries one year before and one year after the SOE that spanned from August 21, 2011 to December 5, 2011. Data were analyzed using SPSS version 19 and a P value <.05 was considered statistically significant.

There were 1,067 patients treated for penetrating injuries. There were significantly more injuries from gunshots compared to stab wounds (64.7% vs 35.3%; P<.001), and this pattern was maintained during the SOE (54.7% vs 45.3%; P=.37). There was a significant fall in mean monthly admissions for penetrating trauma during the SOE when compared to the 12-month period before its imposition (17.7, SD=4.0 vs 38.9, SD=12.3; CI, 5.6-36.8; P=.0108). One year later, mean monthly admissions for penetrating trauma were similar to those during the SOE (22.7, SD=2.1 vs 17.6, SD=4.0; CI, -2.3-12.3; P=.1295). The incidence of gunshot wounds remained low and stab wounds increased.

This study has demonstrated that there was a reduction in the incidence of penetrating trauma at the national trauma center after the SOE, with a shift from gunshot to stab wounds.

Hospital-evacuation decisions are rarely straightforward in protracted advance-warning events. Previous work provides little insight into the decision-making process around evacuation. This study was conducted to identify factors that most heavily influenced the decisions to evacuate the US Department of Veterans Affairs (VA) New York Harbor Healthcare System’s (NYHHS; New York USA) Manhattan Campus before Hurricane Irene in 2011 and before Superstorm Sandy in 2012.

Semi-structured interviews with 11 senior leaders were conducted on the processes and factors that influenced the evacuation decisions prior to each event.

The most influential factor in the decision to evacuate the Manhattan Campus before Hurricane Irene was New York City’s (NYC’s) hospital-evacuation mandate. As a federal facility, the Manhattan VA medical center (VAMC) was exempt from the city’s order, but decision makers felt compelled to comply. In the case of Superstorm Sandy, corporate memory of a similar 1992 storm that crippled the Manhattan facility drove the decision to evacuate before the storm hit.

Results suggest that hospital-evacuation decisions are confounded by political considerations and are influenced by past disaster experience. Greater shared situational awareness among at-risk hospitals, along with a more coordinated approach to evacuation decision making, could reduce pressure on hospitals to make these high-stakes decisions. Systematic mechanisms for collecting, documenting, and sharing lessons learned from past disasters are sorely needed at the institutional, local, and national levels.

Non-invasive positive pressure ventilation (NIPPV) is used to treat severe acute respiratory distress. Prehospital NIPPV has been associated with a reduction in both in-hospital mortality and the need for invasive ventilation.

The authors of this study examined factors associated with NIPPV failure and evaluated the impact of NIPPV on scene times in a critical care helicopter Emergency Medical Service (HEMS). Non-invasive positive pressure ventilation failure was defined as the need for airway intervention or alternative means of ventilatory support.

A retrospective chart review of consecutive patients where NIPPV was completed in a critical care HEMS was conducted. Factors associated with NIPPV failure in univariate analyses and from published literature were included in a multivariable, logistic regression model.

From a total of 44 patients, NIPPV failed in 14 (32%); a Glasgow Coma Scale (GCS) <15 at HEMS arrival was associated independently with NIPPV failure (adjusted odds ratio 13.9; 95% CI, 2.4-80.3; P=.003). Mean scene times were significantly longer in patients who failed NIPPV when compared with patients in whom NIPPV was successful (95 minutes vs 51 minutes; 39.4 minutes longer; 95% CI, 16.2-62.5; P=.001).

Patients with a decreased level of consciousness were more likely to fail NIPPV. Furthermore, patients who failed NIPPV had significantly longer scene times. The benefits of NIPPV should be balanced against risks of long scene times by HEMS providers. Knowing risk factors of NIPPV failure could assist HEMS providers to make the safest decision for patients on whether to initiate NIPPV or proceed directly to endotracheal intubation prior to transport.

Patient transfers among medical facilities are high-risk situations. Despite this, there is very little training of physicians regarding the medical and legal aspects of transport medicine.

To examine the effects of a one hour, educational intervention on Emergency Medicine (EM) residents’ and Critical Care (CC) fellows’ knowledge regarding the medical and legal aspects of interfacility patient transfers.

Prior to the intervention, physician knowledge regarding 12 key concepts in patient transfer was assessed using a pre-test instrument. A one hour, interactive, educational session followed immediately thereafter. Following the intervention, a post-intervention test was given between two and four weeks after delivery. Participants were also asked to describe any prior transportation-medicine-related education, their opinions as they relate to the relevance of the topic, and their comfort levels with patient transfers before and after the intervention.

Only a minority of participants had received any formal training in patient transfers prior to the intervention, despite dealing with patient transfers on a frequent, often daily, basis. Both groups improved in several categories on the post-intervention test. They reported improved comfort levels with the medicolegal aspects of interfacility patient transfers after the intervention and felt well-prepared to manage transfers in their daily practice.

A one hour, educational intervention objectively increased EM and CC physician trainees’ understanding of some of the medicolegal aspects of interfacility patient transfers. The study demonstrated a lack of previous training on this important topic and improved levels of comfort with transfers after study participation.

Needle thoracostomy is the prehospital treatment for tension pneumothorax. Sufficient catheter length is necessary for procedural success. The authors of this study determined minimum catheter length needed for procedural success on a percentile basis.

A meta-analysis of existing studies was conducted. A Medline search was performed using the search terms: needle decompression, needle thoracentesis, chest decompression, pneumothorax decompression, needle thoracostomy, and tension pneumothorax. Studies were included if they published a sample size, mean chest wall thickness, and a standard deviation or confidence interval. A PubMed search was performed in a similar fashion. Sample size, mean chest wall thickness, and standard deviation were found or calculated for each study. Data were combined to create a pooled dataset. Normal distribution of data was assumed. Procedural success was defined as catheter length being equal to or greater than the chest wall thickness.

The Medline and PubMed searches yielded 773 unique studies; all study abstracts were reviewed for possible inclusion. Eighteen papers were identified for full manuscript review. Thirteen studies met all inclusion criteria and were included in the analysis. Pooled sample statistics were: n=2,558; mean=4.19 cm; and SD=1.37 cm. Minimum catheter length needed for success at the 95th percentile for chest wall size was found to be 6.44 cm.

A catheter of at least 6.44 cm in length would be required to ensure that 95% of the patients in this pooled sample would have penetration of the pleural space at the site of needle decompression, and therefore, a successful procedure. These findings represent Level III evidence.

An adequate level of personal protective equipment (PPE) is necessary when treating patients with highly infectious diseases or those contaminated with hazardous substances.

Following National Institute for Health Research’s Research Centre (London, United Kingdom) approval, the authors of this study conducted a survey of specialist registrars’ knowledge of the respiratory and skin protection requirements needed during a resuscitation scenario with Advanced Life Support. Participant responses were compared to UK national recommendations and to a previous survey in 2009.

A total of 98 specialist registrars (in Anesthesiology, n=51; in Emergency Medicine (EM), n=21; and in Intensive Care Medicine (ICM) n=26) completed hand-delivered surveys. The best knowledge of PPE requirements (76%) was found for severe acute respiratory syndrome (SARS), with less knowledge about PPE requirements for anthrax, plague, Ebola virus disease (EVD), and smallpox (60%). The results show limited knowledge of PPE requirements (20%-30%) for various chemical warfare agents. Personal protective equipment knowledge regarding treatment of sarin-contaminated casualties was over-rated by 80%, and for patients with EVD, it was over-rated by up to 67% of participants.

The results of the tested cohort indicate that current knowledge regarding PPE for chemical warfare agents remains very limited.

Management of contaminated patients in the decontamination corridor requires the use of hazardous material (HazMat) personal protective equipment (PPE). Previous studies have demonstrated that HazMat PPE may increase the difficulty of airway management. This study compared the efficiency of video laryngoscopy (VL) with traditional direct laryngoscopy (DL) during endotracheal intubation (ETI) while wearing HazMat PPE.

Post-graduate year (PGY) 1-3 Emergency Medicine residents were randomized to VL or DL while wearing encapsulating PPE. Video laryngoscopy was performed using the GlideScope Cobalt AVL video laryngoscope. The primary outcome measure was time to successful ETI in a high-fidelity simulation mannequin. Three time points were utilized in the analysis: Time 0 (blade at lips), Time 1 (blade removed from lips after endotracheal tube placement), and Time 2 (bag valve mask [BVM] attached to endotracheal tube). Secondary outcome measures were perceived ease of use and feasibility of VL and DL ETI modalities.

Twenty-one of 23 (91.3%) eligible residents participated. Mean time to ETI was 10.0 seconds (SD=5.3 seconds) in the DL group and 7.8 seconds (SD=3.0 seconds) in the VL group (P=.081). Mean times from blade insertion until BVM attachment were 17.4 seconds (SD=6.0 seconds) and 15.6 seconds (SD=4.6 seconds), respectively (P=.30). There were no unsuccessful intubation attempts. Seventeen out of 20 participants (85.0%) perceived VL to be easier to use when performing ETI in PPE. Twelve out of 20 participants (60%) perceived DL to be more feasible in an actual HazMat scenario.

The time to successful ETI was not significantly different between VL and DL. Video laryngoscopy had a greater perceived ease of use, but DL was perceived to be more feasible for use in actual HazMat situations. These findings suggest that both DL and VL are reasonable modalities for use in HazMat situations, and the choice of modality could be based on the clinical situation and provider experience.

In the past two decades, there has been a worldwide increase in the number of disasters, as well as the number of people affected, along with the number of foreign medical teams (FMTs) deployed to provide assistance. However, in the wake of the 2010 Haiti earthquake, multiple reports and anecdotes questioned the actual, positive contribution of such FMTs and even the intentions behind these aid efforts. This brought on a renewed interest in the humanitarian community towards accountability. Between 2000 and 2012, the number of “Quality and Accountability” initiatives and instruments more than tripled from 42 to 147. Yet, to date, there is no single accepted definition of accountability in the humanitarian context.

The aim of this report was to explore and assess how accountability in the humanitarian context is used and/or defined in the literature.

The electronic database PubMed and a predefined list of grey literature comprising 46 organizations were searched for articles that discussed or provided a definition of accountability in the humanitarian context. The definitions found in these articles were analyzed qualitatively using a framework analysis method based on principles of grounded theory as well as using a summative content analysis method.

A total of 85 articles were reviewed in-depth. Fifteen organizations had formal definitions of accountability or explained what it meant to them. Accountability was generally seen in two paradigms: as a “process” or as a “goal.” A total of 16 different concepts were identified amongst the definitions. Accountability to aid recipients had four main themes: empowering aid recipients, being in an optimal position to do the greatest good, meeting expectations, and being liable. The concepts of “enforcement/enforceability” under the last theme of “being liable” received the least mention.

The concept of accountability is defined poorly in many humanitarian organizations. Humanitarian providers often refer to different concepts when talking about accountability in general. The lack of a common understanding is contributed by the semantic and practical complexities of the term. The lack of emphasis on “enforcement/enforceability” is noteworthy. Other aspects of accountability, such as its “measurability” and by whom, similarly lack a common understanding and community-wide consensus. To what extent these vague definitions of accountability affect agencies’ work in the field remains to be documented.

Music festivals, including electronic dance music events (EDMEs), increasingly are common in Canada and internationally. Part of a US $4.5 billion industry annually, the target audience is youth and young adults aged 15-25 years. Little is known about the impact of these events on local emergency departments (EDs).

Drawing on prospective data over a 2-day EDME, the authors of this study employed mixed methods to describe the case mix and prospectively compared patient presentation rate (PPR) and ambulance transfer rate (ATR) between a first aid (FA) only and a higher level of care (HLC) model.

There were 20,301 ticketed attendees. Seventy patient encounters were recorded over two days. The average age was 19.1 years. Roughly 69% were female (n=48/70). Forty-six percent of those seen in the main medical area were under the age of 19 years (n=32/70). The average length of stay in the main medical area was 70.8 minutes. The overall PPR was 4.09 per 1,000 attendees. The ATR with FA only would have been 1.98; ATR with HLC model was 0.52. The presence of an on-site HLC team had a significant positive effect on avoiding ambulance transfers.

Twenty-nine ambulance transfers and ED visits were avoided by the presence of an on-site HLC medical team. Reduction of impact to the public health care system was substantial.

Electronic dance music events have predictable risks and patient presentations, and appropriate on-site health care resources may reduce significantly the impact on the prehospital and emergency health resources in the host community.

Debriefing, a controversial crisis intervention delivered in the early aftermath of a disaster, has not been well evaluated for use with children and adolescents. This report constitutes a review of the child debriefing evidence base.

A systematic search of selected bibliographic databases (EBM Reviews, EMBASE, ERIC, Medline, Ovid, PILOTS, PubMed, and PsycINFO) was conducted in the spring of 2014 using search terms related to psychological debriefing. The search was limited to English language sources and studies of youth, aged 0 to 18 years. No time limit was placed on date of publication. The search yielded 713 references. Titles and abstracts were reviewed to select publications describing scientific studies and clinical reports. Reference sections of these publications, and of other literature known to the authors that was not generated by the search, were used to locate additional materials. Review of these materials generated 187 publications for more thorough examination; this assessment yielded a total of 91 references on debriefing in children and adolescents. Only 15 publications on debriefing in children and adolescents described empirical studies. Due to a lack of statistical analysis of effectiveness data with youth, and some articles describing the same study, only seven empirical studies described in nine papers were identified for analysis for this review. These studies were evaluated using criteria for assessment of methodological rigor in debriefing studies.

Children and adolescents included in the seven empirical debriefing studies were survivors of motor-vehicle accidents, a maritime disaster, hostage taking, war, or peer suicides. The nine papers describing the seven studies were characterized by inconsistency in describing the interventions and populations and by a lack of information on intervention fidelity. Few of the studies used randomized design or blinded assessment. The results described in the reviewed studies were mixed in regard to debriefing’s effect on posttraumatic stress, depression, anxiety, and other outcomes. Even in studies in which debriefing appeared promising, the research was compromised by potentially confounding interventions.

The results highlight the small empirical evidence base for drawing conclusions about the use of debriefing with children and adolescents, and they call for further dialogue regarding challenges in evaluating debriefing and other crisis interventions in children.
