Maintaining Preparedness to Severe Though Infrequent Threats-Can It Be Done?

Use of a Nerve Agent Antidote-Dosing Tool for Mass Casualty Incident Emergency Preparedness

OBJECTIVE

Nerve agent attacks pose a serious threat worldwide and ensuring optimal readiness is essential to management. We review a mass casualty incident (MCI) drill in a busy urban New York City Emergency Department incorporating an antidote-dosing tool.

METHODS

Emergency Management and Preparedness planned an MCI drill involving a nerve agent exposure and engaged the pharmacy department to participate on a more comprehensive level. The clinical pharmacist prepared a treatment tool with antidote dosing recommendations to distribute to team members participating in the drill.

RESULTS

During the launch of the exercise, all clinicians involved reviewed the antidote-dosing tool with the pharmacy team members. Because of the ease of use, limited time was necessary to review the dosing tool before the start of the exercise. After the exercise, feedback regarding the use of the tool was very positive and participants appreciated the tool for use in a theoretical emergency that they have had limited experience managing.

CONCLUSIONS

Optimizing team preparedness with accessible and practical dosing tools may be a helpful addition to emergency preparedness for chemical and biological events with the potential for many casualties.

Review of the requirements for effective mass casualty preparedness for trauma systems. A disaster waiting to happen?

Mass casualty incidents (MCIs) are diverse, unpredictable, and increasing in frequency, but preparation is possible and necessary. The nature of MCIs requires a trauma response but also requires effective and tested disaster preparedness planning. From an international perspective, the aims of this narrative review are to describe the key components necessary for optimisation of trauma system preparedness for MCIs, whether trauma systems and centres meet these components and areas for improvement of trauma system response. Many of the principles necessary for response to MCIs are embedded in trauma system design and trauma centre function. These include robust communication networks, established triage systems, and capacity to secure centres from threats to safety and quality of care. However, evidence from the current literature indicates the need to strengthen trauma system preparedness for MCIs through greater trauma leader representation at all levels of disaster preparedness planning, enhanced training of staff and simulated disaster training, expanded surge capacity planning, improved staff management and support during the MCI and in the post-disaster recovery phase, clear provision for the treatment of paediatric patients in disaster plans, and diversified and pre-agreed systems for essential supplies and services continuity. Mass casualty preparedness is a complex, iterative process that requires an integrated, multidisciplinary, and tiered approach. Through effective preparedness planning, trauma systems should be well-placed to deliver an optimal response when faced with MCIs.

Exercising for mass casualty preparedness

Exercising for mass casualty incidents is mandated by governing organisations with the aim of maintaining readiness within the healthcare sector for the many challenges these incidents bring. This readiness is delivered through a combination of discussion-based and operation-based exercises that are targeted to the needs of both the individuals delivering care and the needs of the overall system of patient flow and treatment. Although exercising for disaster preparedness is resource intensive, it is the repetitive, iterative nature that allows for wide staff capture and exposure along with continual improvement of plans. Having been recently involved in exercising is also likely to increase the confidence of staff and makes them feel better prepared. Exercising should be tailored to the needs and likely challenges of each healthcare system. A cycle of design, challenge, and redesign should target areas of greatest need and greatest benefit. The conventional advice, when introducing exercising, is to start small and build up over time with repeated exercises that demonstrate increasing response capability. However, some organisations would benefit from an exercise that lays bare shortcomings and acts to galvanise change.

Emotional intelligence, cortisol and α-amylase response to highly stressful hyper-realistic surgical simulation of a mass casualty event scenario

Lifetime exposure to stress leads to risk of suffering from cumulative detrimental physiological and psychological ailments. Due to the nature of healthcare and exposure to trauma, medical professionals are particularly susceptible to the negative impacts of high stress environments. emotional intelligence plays a role in ameliorating the risk of being negatively impacted by these stressors. As such, there is special interest to develop and implement training interventions for medical personnel that would allow them to improve emotional intelligence potential with the goal of enabling them to handle stress better and mitigate burnout. A hyper-realistic surgical simulation training session, replicating the intensity of a Mass-Casualty Event scenario, was implemented to allow medical professionals to experience this in real time. Overall, the training led to increased emotional intelligence, correlating with decreased hypothalamus-pituitary-adrenal axis and sympathetic nervous system stress biomarkers, cortisol and α-amylase. This novel training provides, at least, short-term improvements in emotional intelligence that is reflected with a physiological response. These results guide the ongoing effort to develop therapeutic tools to improve long term stress management, mitigate burnout and reduce post-traumatic stress risk after an exposure to a Mass-Casualty event scenario.

•

This study examines the relationship between emotional intelligence and stress response.

•

Higher values in self-perception and stress management correlate with lower cortisol and α-amylase values.

•

Alpha-amylase is more predictive of pre-event emotional intelligence while cortisol levels are better for post-event.

•

Training improves short-term emotional intelligence, that may be useful to enhance stress management and mitigate burnout.

•

Monitoring α-amylase and cortisol levels may help identify individuals at risk or with lower resilience potential.
