Emergency department triage and COVID-19: Performance of the Interagency Integrated Triage Tool during a pandemic surge in Papua New Guinea

Objective: To determine the sensitivity of the Interagency Integrated Triage Tool to identify severe and critical illness among adult patients with COVID-19. Methods: A retrospective observational study conducted at Port Moresby General Hospital ED during a three-month Delta surge. Results: Among 387 eligible patients with COVID-19, 63 were diagnosed with severe or critical illness. Forty-seven were allocated a high acuity triage category, equating to a sensitivity of 74.6% (95% CI 62.1–84.7) and a negative predictive value of 92.7% (95% CI 88.4–95.8). Conclusion: In a resource-constrained context, the tool demonstrated reasonable sensitivity to detect severe and critical COVID-19, comparable with its reported performance for other urgent conditions

Multimodal learning for emergency department triage implementation: experiences from Papua New Guinea during the COVID-19 pandemic

Background: Triage implementation in resource-limited emergency departments (EDs) has traditionally relied on intensive in-person training. This study sought to evaluate the impact of a novel digital-based learning strategy focused on the Interagency Integrated Triage Tool, a three-tier triage instrument recommended by the World Health Organization. Methods: A mixed methods study utilising pre-post intervention methods was conducted in two EDs in Papua New Guinea. The primary outcome was the mean change in knowledge before and after completion of a voluntary, multimodal training program, primarily delivered through a digital learning platform accessible via smartphone. Secondary outcomes included the change in confidence to perform selected clinical tasks, and acceptability of the learning methods. Findings: Among 136 eligible ED staff, 91 (66.9%) completed the digital learning program. The mean knowledge score on the post-training exam was 87.5% (SD 10.4), a mean increase of 12.9% (95% CI 10.7–15.1%, p < 0.0001) from the pre-training exam. There were statistically significant improvements in confidence for 13 of 15 clinical tasks, including undertaking a triage assessment and identifying an unwell patient. In an evaluation survey, 100% of 30 respondents agreed or strongly agreed the online learning platform was easy to access, use and navigate, and that the digital teaching methods were appropriate for their learning needs. In qualitative feedback, respondents reported that limited internet access and a lack of dedicated training time were barriers to participation. Interpretation: The use of digital learning to support triage implementation in resource-limited EDs is feasible and effective when accompanied by in-person mentoring. Adequate internet access is an essential pre-requisite

Reference values of body composition parameters and visceral adipose tissue (VAT) by DXA in adults aged 18–81 years—results from the LEAD cohort

Background Increasing attention has been drawn on the assessment of body composition phenotypes, since the distribution of soft tissue influences cardio-metabolic risk. Dual-energy X-ray absorptiometry (DXA) is a validated technique to assess body composition. European reference values from population-based cohorts are rare. Aims To provide age- and sex-related reference values of body composition parameters and visceral adipose tissue (VAT) mass, and for lean mass index (LMI) with regard to fat mass index (FMI) quantities and BMI categories. Methods GE-Lunar Prodigy DXA scans of 10.894 participants, aged 18–81 years, recruited from 2011 to 2019 by the Austrian LEAD study, a population-based cohort study, have been used to construct reference curves using the LMS method. Parameters assessed are FMI, LMI, appendicular LMI, fat mass ratios android/gynoid and trunk/limbs, and VAT. Results All lean mass and fat mass parameters indicating central fat accumulation were higher in men, whereas other fat mass indices were higher in women. LMI differed between each FMI subgroup (low vs. normal, low vs. high, normal vs. high), and BMI category in all ages and LMI increased with FMI and BMI classes. VAT mass was higher in men compared with women and increased across all age groups within both sexes. Conclusion The present study provides age- and sex-related reference values for European adults aged 18–81 years for body composition parameters and VAT mass for Lunar Prodigy DXA. In addition, this study reports LMI reference values with regard to fat mass quantities, showing a positive association with increasing FMI percentiles and BMI categories.ISSN:0954-3007ISSN:1476-564

Utilização de medidas antropométricas para a avaliação do acúmulo de gordura visceral The use of anthropometric measures to assess visceral fat accumulation

A obesidade visceral tem sido associada ao desenvolvimento de doenças cardiovasculares e a alguns tipos de câncer. Nesse sentido, é crescente o interesse na avaliação da adiposidade intra-abdominal, de forma a se analisarem o risco de doenças e alterações metabólicas, como intolerância à glicose, hiperinsulinemia, diabetes mellitus tipo 2, dislipidemias e hipertensão arterial. Técnicas de imagem, como a tomografia computadorizada e a ressonância magnética, permitem a mensuração acurada e precisa da gordura visceral..Contudo, ambas são dispendiosas e inaplicáveis na prática clínica de rotina e nos estudos epidemiológicos..Parâmetros antro-pométricos surgem como uma opção para a avaliação da gordura visceral nessas situações, por serem inócuos, de fácil aplicação e de baixo custo. À luz dessas questões, este trabalho objetivou analisar criticamente estudos que avaliaram a pertinência em empregar parâmetros antropométricos como indicadores da gordura visceral. Realizou-se um levantamento bibliográfico, no qual foram consultados periódicos nacionais e internacionais disponíveis nas seguintes bases científicas: Portal de periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, Scientific Electronic Library Online, Science Direct e Pubmed, abrangendo publicações entre os anos de 1947 e 2007. Procurou-se dar ênfase aos parâmetros antropométricos, como o índice de massa corporal, a circunferência da cintura, a relação cintura-quadril e o diâmetro abdominal sagital.<br>Visceral obesity has been associated with the development of cardiovascular diseases and some types of cancer. Therefore, there is an increasing interest in quantifying intra-abdominal adiposity in order to assess the risk of metabolic disorders, such as glucose intolerance, hyperinsulinemia, type 2 diabetes, dyslipidemia and hypertension. Imaging techniques such as computed tomography and magnetic resonance provide an accurate and precise measurement of visceral fat. However, both are costly and inapplicable in routine clinical practice and epidemiological studies. Anthropometric parameters are an option for visceral fat assessment in these situations, since they are innocuous, easy to use and inexpensive. In this context, this work aimed to critically analyze studies that assessed anthropometric parameters as indicators of visceral fat. A bibliographic review of domestic and international articles found in the databases Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, Scientific Electronic Library Online, Science Direct and Pubmed, published from 1947 to 2007 was done. Emphasis was given to anthropometric parameters, such as body mass index, waist circumference, waist-to-hip ratio and sagittal abdominal diameter
