RESUMO

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.

RESUMO

Introduction: Out-of-hospital-cardiac-arrest (OHCA) is a major public health challenge and post-return-of-spontaneous-circulation (ROSC) goals have shifted from just survival to survival with intact neurology. Although post-ROSC care is crucial for survival with intact neurology, there are insufficient well-established protocols for post-resuscitation care. We aimed to evaluate post-resuscitation care in the emergency department (ED) of adult (aged ≥16 years) OHCA patients with sustained ROSC and its associated neurologically intact survival. Methods: A retrospective review of electronic medical records was conducted for OHCA patients with sustained ROSC at the ED. Data including demographics, pre-hospital resuscitation, ED resuscitation, post-resuscitation care and eventual outcomes were analysed. Results: Among 921 OHCA patients, 85 (9.2%) had sustained ROSC at the ED. Nineteen patients (19/85, 22.4%) survived, with 13 (13/85, 15.3%) having intact neurology at discharge. Electrocardiogram and chest X-ray were performed in all OHCA patients, whereas computed tomography (CT) was performed inconsistently, with CT brain being most common (74/85, 87.1%), while CT pulmonary angiogram (6/85, 7.1%), abdomen and pelvis (4/85, 4.7%) and aortogram (2/85, 2.4%) were done infrequently. Only four patients (4.7%) had all five neuroprotective goals of normoxia, normocarbia, normotension, normothermia and normoglycaemia achieved in the ED. The proportion of all five neuroprotective goals being met was significantly higher (P = 0.01) among those with neurologically intact survival (3/13, 23.1%) than those without (1/72, 1.4%). Conclusion: Post-resuscitation care at the ED showed great variability, indicating gaps between recommended guidelines and clinical practice. Good quality post-resuscitation care, centred around neuroprotection goals, must be initiated promptly to achieve meaningful survival with intact neurology.

RESUMO

Introduction: Paediatric patients admitted to the inpatient units from the emergency department (ED) are increasing, but the mean length of stay has fallen significantly. We aimed to determine the reasons behind paediatric one-day admissions in Singapore and to assess their necessity. Methods: A retrospective study involving paediatric patients who were admitted from a general ED of an adult tertiary hospital to a paediatric tertiary hospital between 1 August 2018 and 30 April 2020. One-day admission was defined as an inpatient stay of less than 24 h from the time of admission to discharge. An unnecessary admission was defined as one with no diagnostic test ordered, intravenous medication administered, therapeutic procedure performed or specialty review made in the inpatient unit. Data were captured in a standardised form and analysed. Results: There were 13,944 paediatric attendances - 1,160 (8.3%) paediatric patients were admitted. Among these, 481 (41.4%) were one-day admissions. Upper respiratory tract infection (62, 12.9%), gastroenteritis (60, 12.5%) and head injury (52, 10.8%) were the three most common conditions. The three most common reasons for ED admissions were inpatient treatment (203, 42.2%), inpatient monitoring (185, 38.5%) and inpatient diagnostic investigations (32, 12.3%). Ninety-six (20.0%) one-day admissions were unnecessary. Conclusion: Paediatric one-day admissions present an opportunity to develop and implement interventions targeted at the healthcare system, the ED, the paediatric patient and their caregiver, in order to safely slow down and perhaps reverse the trend of increased hospital admissions.

RESUMO

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.

RESUMO

AIMS: Ultrasound guided nerve blocks have been shown to be an effective analgesia option for patients with hip fracture. An education program was developed to train Emergency Department doctors and it received positive feedback from partici-pants who demonstrated competency after the training. We aimed to evaluate the education program at the behavioral level of the Kirkpatrick Model by determining the translation of training to practice of ultrasound guided nerve blocks in patients with a hip fracture at the Emergency Department. MATERIALS AND METHODS: A retrospective review of medical records was carried out from 18 August 2018 to 31 December 2020. Data on patient demographics, type of hip fracture, pain score, analgesia pro-vided and complications were collected using a standardized form and analyzed. RESULTS: Among 634 patients, their median age was 79 years old (Interquartile range (IQR): 70 to 85) and 416 (65.6%) were female. The median pain score was 6 (IQR: 5 to 8) and analgesia was provided for 561 (88.5%) patients. Analgesia was administered most frequently via the intravenous route (n=407, 72.5%) and tramadol (n=293, 52.2%) was most commonly used. Ultrasound guided nerve block was performed in 26 (4.7%) patients - all were performed successfully without complications. The utilization increased from 1.0% before to 4.7% after the conduct of the training workshops (p=0.16). CONCLUSION: A significant gap still exists in the translation of training to practice. Barriers must be identified and overcome so that ultimately, the education program can bring about an organizational impact to benefit patients and improve their outcomes.

RESUMO

Objective: Current knowledge on the global burden of infant sepsis is limited to population-level data. We aimed to summarize global case fatality rates (CFRs) of young infants with sepsis, stratified by gross national income (GNI) status and patient-level risk factors. Methods: We performed a systematic review and meta-analysis on CFRs among young infants < 90 days with sepsis. We searched PubMed, Cochrane Central, Embase, and Web of Science for studies published between January 2010 and September 2019. We obtained pooled CFRs estimates using the random effects model. We performed a univariate analysis at patient-level and a meta-regression to study the associations of gestational age, birth weight, onset of sepsis, GNI, age group and culture-proven sepsis with CFRs. Results: The search yielded 6314 publications, of which 240 studies (N = 437,796 patients) from 77 countries were included. Of 240 studies, 99 were conducted in high-income countries, 44 in upper-middle-income countries, 82 in lower-middle-income countries, 6 in low-income countries and 9 in multiple income-level countries. Overall pooled CFR was 18% (95% CI, 17-19%). The CFR was highest for low-income countries [25% (95% CI, 7-43%)], followed by lower-middle [25% (95% CI, 7-43%)], upper-middle [21% (95% CI, 18-24%)] and lowest for high-income countries [12% (95% CI, 11-13%)]. Factors associated with high CFRs included prematurity, low birth weight, age less than 28 days, early onset sepsis, hospital acquired infections and sepsis in middle- and low-income countries. Study setting in middle-income countries was an independent predictor of high CFRs. We found a widening disparity in CFRs between countries of different GNI over time. Conclusion: Young infant sepsis remains a major global health challenge. The widening disparity in young infant sepsis CFRs between GNI groups underscore the need to channel greater resources especially to the lower income regions.

RESUMO

AIM: This study explored how body habitus in the paediatric population might potentially affect the use of one-third external anterior-posterior (APD) diameter when compared to age-appropriate absolute chest compression depth targets. It also explored how body habitus could potentially affect the relationship between one-third external and internal APD (compressible space) and if body habitus indices were independent predictors of internal APD at the lower half of the sternum. METHODS: This was a secondary analysis of a retrospective study of chest computed tomography (CT) scans of infants and children (>24-hours-of-life to less-than-18-years-old) from 2005 to 2017. Patients' scan images were reviewed for internal and external APDs at the mid-point of the lower half of the sternum. Body habitus and epidemiological data were extracted from the electronic medical records. RESULTS: Chest CT scans of 193 infants and 398 children were evaluated. There was poor concordance between one-third external APD measurements and age-specific absolute chest compression depth targets, especially in infants and overweight/obese adolescents. There was a co-dependent relationship between one-third external APD and internal APD measurements. Overweight/obese children's and adolescents' internal and external APDs were significant different from the normal/underweight groups. Body-mass-index (BMI) of children and adolescents (p = 0.009), but not weight-for-length (WFL) of infants (p = 0.511), was an independent predictor of internal APD at the compression landmark. CONCLUSION: This study demonstrated correlations between external and internal APDs which were affected by BMI but not WFL (infants). Clinical studies are needed to validate current chest compression guidelines especially for infants and overweight/obese adolescents.(250 words).

RESUMO

BACKGROUND: Left ventricular assist devices (LVADs) can be used as a bridging therapy for myocardial recovery or cardiac transplant, as well as a destination therapy for long-term support in patients with advanced heart failure. Patients with LVADs can present to the emergency department (ED) for acute deterioration and emergency physicians (EPs) must be equipped with the necessary knowledge and skill to treat this unique population. OBJECTIVE: This review describes the role of point-of-care ultrasound (POCUS) in the evaluation of patients with LVADs and illustrates how EPs can incorporate POCUS into the evaluation of these patients in the ED. DISCUSSION: The clinical applications for which POCUS may be useful in patients with LVADs include hypotension or shock, dyspnea, cardiac failure, dysrhythmia, syncope, and cardiac arrest. The normal features of POCUS in patients with LVADs and the features of POCUS associated with diseased states are presented. CONCLUSIONS: Patients with LVADs have altered anatomy and physiology. Therefore, an understanding of key modifications to standard POCUS views is necessary so that EPs can use POCUS effectively in their evaluation of these patients.

RESUMO

BACKGROUND: Computed tomography (CT) is associated with a risk of cancer development. Strategies to reduce radiation doses vary between centers. We compared radiation doses of CT brain studies between pediatric and general emergency departments (EDs), and determine the proportion studies performed within the reference levels recommended by the International Commission on Radiological Protection (ICRP). METHODS: A retrospective review was carried out in a healthcare network consisting of one pediatric ED and three general hospital EDs. Pediatric patients less than 16 years old with CT brain studies performed between 1 January 2015 and 31 December 2018 were included. Information on demographic, diagnosis, volume-averaged computed-tomography dose index and dose length product (DLP) were collected. Effective dose was then calculated from DLP using conversion factors, termed k-coefficients which were derived using a 16 cm head CT dose phantom. RESULTS: Four hundred and seventy-nine CT brain studies were performed - 379 (79.1%) at the pediatric ED. Seizure (149, 31.1%), head injury (147, 30.7%) and altered mental status (44, 9.2%) were the top three ED diagnoses. The median effective dose estimates were higher in general than pediatric EDs, particularly for those aged > 3 to ≤6 years old [1.57 mSv (IQR 1.42-1.79) versus 1.93 mSv (IQR 1.51-2.28), p = 0.047], > 6 to ≤10 years old [1.43 mSv (IQR 1.27-1.67) versus 1.94 mSv (IQR 1.61-2.59), p = 0.002) and > 10 years old (1.68 mSv (IQR 1.32-1.72) versus 2.03 mSv (IQR 1.58-2.88), p < 0.001). Overall, 233 (48.6%) and 13 (2.7%) studies were within the reference levels recommended by ICRP 60 and 103 respectively. CONCLUSIONS: Radiation doses for CT brain studies were significantly higher at general EDs and less than half of the studies were within the reference levels recommended by ICRP. The development of diagnostic reference levels (DRLs) as a benchmark and clinical justification for performing CT studies can help reduce the radiation risks in the pediatric population.

RESUMO

AIM: We explored the potential for over-compression from current paediatric chest compression depth guidelines using chest computed tomography(CT) images of a large, heterogenous, Asian population. METHODS: A retrospective review of consecutive children, less than 18-years old, with chest CT images performed between from 2005 to 2017 was done. Demographic data were extracted from the electronic medical records. Measurements for internal and external anterior-posterior diameters (APD) were taken at lower half of the sternum. Simulated chest compressions were performed to evaluate the proportion of the population with residual internal cavity dimensions less than 0 mm (RICD < 0 mm, representing definite over-compression; with chest compression depth exceeding internal APD), and RICD less than 10 mm (RICD < 10 mm, representing potential over-compression). RESULTS: 592 paediatric chest CT studies were included for the study. Simulated chest compressions of one-third external APD had the least potential for over-compression; no infants and 0.3% children had potential over-compression (RICD < 10 mm). 4 cm simulated chest compressions led to 18% (95% CI 13%-24%) of infants with potential over-compression, and this increased to 34% (95% CI 27%-41%) at 4.4 cm (upper limit of "approximately" 4 cm; 4 cm + 10%). 5 cm simulated compressions resulted in 8% (95% CI 4%-12%) of children 1 to 8-years-old with potential over-compression, and this increased to 22% (95% CI 16%-28%) at 5.5 cm (upper limit of "approximately" 5 cm, 5 cm + 10%). CONCLUSION: In settings whereby chest compression depths can be accurately measured, compressions at the current recommended chest compression of approximately 4 cm (in infants) and 5 cm (in young children) could result in potential for over-compression.

RESUMO

BACKGROUND: Pediatric patients present to Emergency Departments (EDs) with a variety of medical conditions. An appreciation of the common presenting conditions can aid EDs in the provision of pediatric emergency care. In this study, we established the common pediatric diagnoses seen at the general EDs, with reference to a pediatric ED. METHODS: A retrospective review of medical records was performed for patients less than 16 years old at a pediatric ED and two general EDs from 1 January to 31 December 2018. Information including patient demographics, triage category, case type and diagnoses were collected. RESULTS: There were 159,040 pediatric attendances, of which 3477 (2.2%) were seen at the general EDs. Non-traumatic conditions were most prevalent at both general (N = 1933, 55.6%) and pediatric (N = 128,415, 82.5%) EDs. There was a higher proportion of trauma related conditions seen at the general EDs (N = 1544, 44.4%) compared to the pediatric ED (N = 27,148, 17.5%; p < 0.01). Across all EDs, upper respiratory tract infection, unspecified musculoskeletal pain and gastroenteritis were the three most common non-trauma related diagnoses, while fracture, wound and contusion were the three most common trauma related diagnoses. There was a greater proportion of emergent (P1) cases seen at the general EDs (N = 233, 6.7%) than the pediatric ED (N = 3821, 2.5%; p < 0.01). Respiratory conditions including bronchiolitis, asthma and bronchitis were the most common emergent (P1) diagnoses. CONCLUSIONS: The common diagnoses among pediatric attendances varied between pediatric and general EDs. Therefore, general EDs should focus their efforts on these common diagnoses, especially the emergent (P1) ones, so that they can enhance their preparedness and work towards providing quality pediatric emergency care.

RESUMO

BACKGROUND: Intubation is a life-saving intervention at the Emergency Department (ED). However, general and pediatric EDs may vary in their preparedness to manage children with airway emergencies. AIMS: We aimed to compare rates of first-pass intubation and adverse tracheal intubation-associated events between general and pediatric EDs. METHODS: A retrospective review of medical records was conducted at a pediatric ED and three general EDs from January 1, 2015, to December 31, 2018. Information about the intubation process involving pediatric patients (less than 16 years old), as well as eventual outcomes of first-pass intubation and adverse tracheal intubation-associated events were collected and analyzed. RESULTS: There were 180 pediatric intubations, of which 115 (63.9%) were performed in pediatric ED. The median age was 2 years old (interquartile range 0-6). Intubation was most commonly performed for patients with cardiac arrest (88, 48.9%). Direct laryngoscopy was used in 178 (98.9%) cases and uncuffed tube was used in 135 (75.0%) cases. Apneic oxygenation was performed in 26 (14.4%) cases-all in pediatric ED. Intubation was predominantly performed by senior clinicians (162, 90.0%). Overall, intubation was performed successfully in 175 (97.2%) cases, with a first-pass intubation rate of 82.2% which was similar between pediatric (96, 83.5%) and general EDs (52, 80%) (Odds ratio [OR] 1.26, 95% confidence interval [CI] 0.58 to 2.76, p = .558). There were 68 adverse tracheal intubation-associated events with right mainstem intubation being the most common (23, 12.8%). Pediatric EDs (44, 38.3%) had a higher rate of adverse tracheal intubation-associated events than general EDs (15, 23.1%) (OR 2.07, 95% CI 1.04 to 4.11; p = .037). CONCLUSIONS: Differences exist in intubation outcomes between pediatric and general EDs. Quality improvement efforts should focus on standardizing intubation practices across both pediatric and general EDs.

RESUMO

This study examines the impact of a newly developed structured training on Singapore paramedics' psychological comfort before the implementation of a prehospital termination of resuscitation (TOR) protocol. Following a before and after study design, the paramedics underwent a self-administered questionnaire to assess their psychological comfort level applying the TOR protocol, 22 months before and one month after a 3-h structured training session. The questionnaire addressed five domains: sociocultural attitudes on resuscitation and TOR, multi-tasking, feelings towards resuscitation and TOR, interactions with colleagues and bystanders and informing survivors. Overall psychological comfort total (PCT) scores and domain-specific scores were compared using the paired t-test with higher scores representing greater comfort. Ninety-six of the 345 eligible paramedics responded. There was no statistically significant change in the mean PCT scores at baseline and post-training; however, the "feelings towards resuscitation and TOR" domain improved by 4.77% (95% CI 1.42 to 8.13 and p = 0.006) and the multi-tasking domain worsened by 4.11% (95% CI -7.82 to -0.41 and p = 0.030). While the structured training did not impact on the overall psychological comfort levels, it led to improvements in the feelings of paramedics towards resuscitation and TOR. Challenges remain in improving paramedics' psychological comfort levels towards TOR.

RESUMO

Disasters are often unforeseen events. Hospitals form a critical component of any country's disaster management medical support system. To ensure optimal operations, minimize chaos, and allow flexibility in response, planning and practice are crucial. Singapore Health Services (SingHealth) collaborated with Hasanuddin University (UnHas) in Makassar, Indonesia, to develop a Hospital Disaster Medical Support (HDMS) program for the province of South Sulawesi, Indonesia. An assessment of the needs of the hospitals in Makassar, Indonesia, for disaster preparedness was carried out. A curriculum for the HDMS program was developed based on the assessment. Discussions with stakeholders of various hospitals were held for the implementation of this program. A total of 310 participants were trained in this program over the two-year period. The feedback from the participants was positive. The exercises provided a more realistic simulation of the concepts of hospital management in a disaster situation. Up to 73 persons were also trained as program instructors during this period. The development of the cadre of instructors in hospital disaster medical support will likely help sustain the program for the next few years.
