Use of Simulation in Full-Scale Exercises for Response to Disasters and Mass-Casualty Incidents: A Scoping Review.

Disasters or mass-casualty incidents are uncommon events. The use of simulation is an ideal training modality in full-scale exercises as it immerses the participants in a replication of the actual environment where they can respond to simulated casualties in accordance with existing protocols.The objective of this scoping review is to answer the research question: "How effective is simulation, as assessed in full-scale exercises, for response to disasters and mass-casualty incidents world-wide?" Studies on full-scale exercises, as defined in World Health Organization (WHO) simulation exercise toolbox, that were published in peer-reviewed journals using the English language from 2001 through 2021 were included. Twenty studies were included from searching PubMed, Embase, and Web of Science. Simulated casualties were the most common simulation modality. Using Kirkpatrick's levels of evaluation to synthesize the data, simulation was reported to be generally effective and mostly demonstrated at the levels of learning of individuals and/or systems, as well as reaction of individuals. Evaluations at levels of behavior and results were limited due to the uncommon nature of disasters and mass-casualty incidents. However, evaluation outcomes across the full-scale exercises were varied, leading to the inability to consolidate effectiveness of simulation into a single measure. It is recommended for best evidence-based practices for simulation to be adhered to in full-scale exercises so that the trainings could translate into better outcomes for casualties during an actual disaster or mass-casualty incident. In addition, the reporting of simulation use in full-scale exercises should be standardized using a framework, and the evaluation process should be rigorous so that effectiveness could be determined and compared across full-scale exercises.

Assessing Knowledge, Attitudes, and Perceptions of Medical Students Toward Emergency Preparedness and Disaster Medicine in Singapore.

OBJECTIVE: Despite rising incidences of global disasters, basic principles of disaster medicine training are barely taught in Singapore's 3 medical schools. The aim of this study was to evaluate the current levels of emergency preparedness, attitudes, and perceptions of disaster medicine education among medical students in Singapore. METHODS: The Emergency Preparedness Information Questionnaire (EPIQ) was provided to enrolled medical students in Singapore by means of an online form, from March 6, 2020, to February 20, 2021. A total of 635 (25.7%) responses were collated and analyzed. RESULTS: Mean score for overall familiarity was low, at 1.50 ± 0.74, on a Likert scale of 1 for not familiar to 5 for very familiar. A total of 90.6% of students think that disaster medicine is an important facet of the curriculum, and 93.1% agree that training should be provided for medical students. Although 77.3% of respondents believe that they are unable to contribute to a disaster scenario currently, 92.8% believe that they will be able to contribute with formal training. CONCLUSIONS: Despite low levels of emergency preparedness knowledge, the majority of medical students in Singapore are keen for adaptation of disaster medicine into the current curriculum to be able to contribute more effectively. This can arm future health-care professionals with the confidence to respond to any potential emergency.

Patient-controlled analgesia for the management of adults with acute trauma in the emergency department: A systematic review and meta-analysis.

BACKGROUND: Patient-controlled analgesia (PCA) has potential as a form of analgesia for trauma patients in the emergency department (ED). The objective of this review was to evaluate the effectiveness and safety of PCA for the management of adults with acute traumatic pain in the ED. The hypothesis was that PCA can effectively treat acute trauma pain in adults in the ED, with minimal adverse outcomes and better patient satisfaction compared with non-PCA modalities. METHODS: MEDLINE (PubMed), Embase, SCOPUS, ClinicalTrials.gov , and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from inception date to December 13, 2022. Randomized controlled trials involving adults presenting to the ED with acute traumatic pain who received intravenous (IV) analgesia via PCA compared with other modalities were included. The Cochrane Risk of Bias tool and the Grading of Recommendation, Assessment, Development, and Evaluation approach were used to assess the quality of included studies. RESULTS: A total of 1,368 publications were screened, with 3 studies involving 382 patients meeting the eligibility criteria. All three studies compared PCA IV morphine with clinician-titrated IV morphine boluses. For the primary outcome of pain relief, the pooled estimate was in favor of PCA with a standard mean difference of -0.36 (95% confidence interval, -0.87 to 0.16). There were mixed results concerning patient satisfaction. Adverse event rates were low overall. The evidence from all three studies was graded as low-quality because of a high risk of bias from lack of blinding. CONCLUSION: This study did not demonstrate a significant improvement in pain relief or patient satisfaction using PCA for trauma in the ED. Clinicians wishing to use PCA to treat acute trauma pain in adult patients in the ED are advised to consider the available resources in their own practice settings and to implement protocols for monitoring and responding to potential adverse events. LEVEL OF EVIDENCE: Systematic Review/Meta-Analyses; Level III.

Developing the Disaster Medical Responder's Course in Singapore.

Problem: Emergency medical teams (EMTs) deployed to mass casualty incidents (MCIs) are required to work outside their usual settings and according to different principles, which may affect their performance and the survival of casualties. Prior to 2013, training offered to domestic EMTs was limited to ad hoc and infrequent simulation exercises. Context: Domestic EMTs are activated from public tertiary hospitals to provide pre-hospital medical support to the Singapore Civil Defence Force and establish a first-aid post (FAP) for triaging, stabilizing and treating casualties. These casualties are then evacuated to public hospitals for further management. Action: Recognizing the need for a more systematic approach to the training of domestic EMTs, the Disaster Medical Responder's Course (the Course) was developed as a multiinstitutional collaboration to equip EMT members attending a MCI with the necessary skills to perform effectively at the FAP. Outcome: The Course was first run in 2013 and is usually offered six to eight times a year. Since June 2019, a total of 414 health-care staff and allied health professionals have participated. There have been numerous revisions of the course content and delivery to reflect the latest concepts in operations and global best practice, as well as developments in educational methodologies. Discussion: Preparedness is crucial to optimize the survival and outcomes of casualties. The Course provides standardized training of domestic EMTs and plays a pivotal role in ensuring operational readiness for MCIs in Singapore.

Reorganising the emergency department to manage the COVID-19 outbreak.

BACKGROUND: The COVID-19 disease outbreak that first surfaced in Wuhan, China, in December 2019, has taken the world by storm and ravaged almost every country in the world. Emergency departments (ED) in hospitals are on the frontlines, serving an essential function in identifying these patients, isolating them early whilst providing urgent medical care. This outbreak has reinforced the role of Emergency Medicine in public health. This paper documents the challenges faced and measures taken by a tertiary hospital's ED in Singapore, in response to the outbreak. MAIN BODY: The ED detected the first case of COVID-19 in Singapore on 22 January 2020 in a Chinese tourist and also the first case of locally transmitted COVID-19 on 3 February 2020. The patient journeys through the patient reception area in the ED and undergoes fever screening before being shunted to isolation areas within the ED. Management and disposition of suspect COVID-19 patients are guided by a close-knit collaboration between ED and department of infectious diseases. With increasing number of patients, back-up plans for expansion of space and staff augmentation have been enacted. Staff safety is also of utmost importance, with provision and guidelines for personal protective equipment and team segregation to ensure no cross-contamination across staff. These have been made possible with an early setup of an operational command and control structure within the ED, managing manpower, logistics, operations, communication and information management and liaison with other clinical departments. CONCLUSION: With the large numbers of undifferentiated patients managed by the ED to date, more than 820 patients with COVID-19 have been identified in the hospital. Not a single member of the staff of the SGH Emergency Department has come down with the illness. The various measures undertaken by the department have helped to ensure good staff morale and strict adherence to safety procedures. We share the lessons learnt so that others who manage EDs around the world can benefit from our experience.

Emergency department 'outbreak rostering' to meet challenges of COVID-19.

The COVID-19 outbreak has posed unique challenges to the emergency department rostering. Additional infection control, the possibility of quarantine of staff and minimising contact among staff have significant impact on the work of doctors in the emergency department. Infection of a single healthcare worker may require quarantine of close contacts at work. This may thus affect a potentially large number of staff. As such, we developed an Outbreak Response Roster. This Outbreak Response Roster had fixed teams of doctors working in rotation, each team that staff the emergency department in turn. Members within teams remained constant and were near equally balanced in terms of manpower and seniority of doctors. Each team worked fixed 12 hours shifts with as no overlapping of staff or staggering of shifts. Handovers between shifts were kept as brief as possible. All these were measures to limit interactions among healthcare workers. With the implementation of the roster, measures were also taken to bolster the psychological wellness of healthcare workers. With face-to-face contact limited, we also had to maintain clear, open channels for communication through technology and continue educating residents through innovative means.
