Erythema and induration of the Bacillus Calmette-Guérin site for diagnosing Kawasaki disease

INTRODUCTION@#Kawasaki disease (KD) is a challenging diagnosis. Erythema and induration of the Bacillus Calmette-Guérin (BCG) site is increasingly recognised as a significant clinical clue. However, there is little data to support its specificity for KD as compared to other febrile illnesses. We aimed to evaluate BCG reaction or induration as a diagnostic tool for KD.@*METHODS@#A retrospective case-controlled study of patients discharged with a diagnosis of KD from 2007 to 2010 was conducted. Another group of patients admitted over the same period for possible KD, but later found not to have KD, served as control.@*RESULTS@#Significantly more infants with KD (69.7%) had BCG site changes than older children (27.8%; p < 0.001). It also presented earlier in the course of KD; < 5 days (53.3%) compared to ≥ 5 days of fever (30.0%; p < 0.001). Positive predictive value of BCG site reaction or induration for KD was 90.8% (95% confidence interval [CI] 0.819-0.962) for infants and 96.2% (95% CI 0.868-0.995) for older children. The prevalence rate of changes at the BCG site was 9.9% among patients with non-KD febrile illnesses and 42.6% among patients with KD.@*CONCLUSION@#BCG site reaction or induration is a useful clinical clue for the diagnosis of KD in both infants and older children, with a higher prevalence in infants. Physicians should consider KD in children with febrile illness and redness or crust formation at the BCG site, especially in view of low rates of BCG reaction or induration in non-KD febrile illnesses.

Knowledge and attitudes of Singapore schoolchildren learning cardiopulmonary resuscitation and automated external defibrillator skills

<p><b>INTRODUCTION</b>Victims of out-of-hospital cardiac arrests require timely cardiopulmonary resuscitation (CPR) and early defibrillation. Callers to emergency medical services are asked to provide dispatcher-guided responses until an ambulance arrives. Knowing what to expect in such circumstances should reduce both delay and confusion.</p><p><b>METHODS</b>This study was conducted among schoolchildren aged 11-17 years using ten-item pre- and post-training surveys. We aimed to observe any knowledge and attitude shifts regarding CPR and automated external defibrillator (AED) use subsequent to the training.</p><p><b>RESULTS</b>A total of 1,196 students across five schools completed the pre- and post-training surveys. Survey questions tested basic CPR knowledge and attitudes towards CPR and AED use. The overall response rate was 80.8% and 81.5% in the pre- and post-training surveys, respectively. There was a statistically significant improvement in the students' CPR knowledge. The number of students who selected all the correct answers for the knowledge-based questions in the post-training survey increased by 64.7% (95% confidence interval 61.9%-67.5%; p < 0.001). There was also an improvement in their willingness to administer CPR (likely/very likely to administer CPR pre-training vs. post-training: 13.0% vs. 71.0%; p < 0.001) and use AED (likely/very likely to administer AED pre-training vs. post-training: 11.7% vs. 78.0%; p < 0.001) after training.</p><p><b>CONCLUSION</b>The training programme imparted new information and skills, and improved attitudes towards providing CPR and using AED. However, some concerns persisted about hurting the victim while performing CPR.</p>

Measuring the effectiveness of a novel CPRcard™ feedback device during simulated chest compressions by non-healthcare workers

<p><b>INTRODUCTION</b>There is a need for a simple-to-use and easy-to-carry CPR feedback device for laypersons. We aimed to determine if a novel CPRcard™ feedback device improved the quality of chest compressions.</p><p><b>METHODS</b>We compared participants' chest compression rate and depth with and without feedback. Compression data was captured through the CPRcard™ or Resusci Anne's SimPad® SkillReporter™. Compression quality was defined based on 2010 international guidelines for rate, depth and flow fraction.</p><p><b>RESULTS</b>Overall, the CPRcard group achieved a better median compression rate (CPRcard 117 vs. control 122, p = 0.001) and proportion of compressions within the adequate rate range (CPRcard 83% vs. control 47%, p < 0.001). Compared to the no-card and blinded-card groups, the CPRcard group had a higher proportion of adequate compression rate (CPRcard 88% vs. no-card 46.8%, p = 0.037; CPRcard 73% vs. blinded-card 43%, p = 0.003). Proportion of compressions with adequate depth was similar in all groups (CPRcard 52% vs. control 48%, p = 0.957). The CPRcard group more often met targets for compression rate of 100-120/min and depth of at least 5 cm (CPRcard 36% vs. control 4%, p = 0.022). Chest compression flow fraction rate was similar but not statistically significant in all groups (92%, p = 1.0). Respondents using the CPRcard expressed higher confidence (mean 2.7 ± 2.4; 1 = very confident, 10 = not confident).</p><p><b>CONCLUSION</b>Use of the CPRcard by non-healthcare workers in simulated resuscitation improved the quality of chest compressions, thus boosting user confidence in performing compressions.</p>

Understanding decisions leading to nonurgent visits to the paediatric emergency department: caregivers' perspectives

<p><b>INTRODUCTION</b>A significant percentage of paediatric emergency department (ED) attendances worldwide are nonurgent, adversely affecting patient outcomes and healthcare systems. This study aimed to understand the reasons behind nonurgent ED visits, in order to develop targeted and effective preventive interventions.</p><p><b>METHODS</b>In-depth interviews were conducted with 49 caregivers to identify the decision-making factors related to taking children to the ED of KK Women's and Children's Hospital, Singapore. Interviews were carried out in the emergency room of the hospital after the children had been diagnosed with nonurgent conditions by the attending physician. Interview transcripts were analysed based on grounded theory principles.</p><p><b>RESULTS</b>The demographics of our study cohort were representative of the target population. The main reasons given by the caregivers for attending paediatric EDs included perceived severity of the child's symptoms, availability of after-hours care, perceived advantage of a paediatric specialist hospital and mistrust of primary care physicians' ability to manage paediatric conditions. Insurance or welfare was a contributing factor for only a small portion of caregivers.</p><p><b>CONCLUSION</b>The reasons provided by Singaporean caregivers for attending paediatric EDs were similar to those reported in studies conducted in Western countries. However, the former group had a unique understanding of the local healthcare system. The study's findings may be used to develop interventions to change the knowledge, attitudes and behaviours of caregivers in Singapore.</p>
