Evaluating the internalisation of the intrinsic role of health advocacy of student pharmacists in a new integrated Bachelor of Pharmacy curriculum: a mixed-methods study.

To keep up with the contemporary health landscape, there is an imperative need for healthcare professionals to practise health advocacy through health promotion on the individual, population, and systems levels. In the Academic Year of 2020/2021, the National University of Singapore (NUS) Department of Pharmacy implemented a new spiral curriculum integrating basic, clinical, and systems sciences with one of its aims to deepen students' health advocacy internalisation and prepare them as future health advocates. A mixed-methods approach was adopted. Questionnaires were disseminated across three time-points to elicit students' levels of internalisation of health advocacy, which were then categorised into levels, and a Mann-Whitney U test was conducted. In comparison with prematriculation, no significant difference was found after students underwent the first year of the curriculum, while a significant difference was found after students underwent two years of the curriculum. Semi-structured interviews were also conducted after each Academic Year to gain deeper insights into the questionnaire results. Thematic analysis of the interviews revealed that curricular integration in the first year was perceived to be lacking. However, with learnt knowledge constantly reinforced and more experiential learning opportunities incorporated throughout the second year, students found the integrated curriculum beneficial in instilling confidence to practise health advocacy. This study offers insights into the prospects of a spiral integrated curriculum in imparting health advocacy, and may even suggest its potential to be applied to other educational settings. Future follow-up studies can also be conducted on the same study population to evaluate long-term impacts and areas for improvement of the curriculum.

Point of care ultrasound: a clinical decision support tool for COVID-19.

The COVID-19 global pandemic has overwhelmed health services with large numbers of patients presenting to hospital, requiring immediate triage and diagnosis. Complications include acute respiratory distress syndrome, myocarditis, septic shock, and multiple organ failure. Point of care ultrasound is recommended for critical care triage and monitoring in COVID-19 by specialist critical care societies, however current guidance has mainly been published in webinar format, not a comprehensive review. Important limitations of point of care ultrasound include inter-rater variability and subjectivity in interpretation of imaging findings, as well as infection control concerns. A practical approach to clinical integration of point of care ultrasound findings in COVID-19 patients is presented to enhance consistency in critical care decision making, and relevant infection control guidelines and operator precautions are discussed, based on a narrative review of the literature.

Trauma-induced coagulopathy: Mechanisms and clinical management.

INTRODUCTION: Trauma-induced coagulopathy (TIC) is a form of coagulopathy unique to trauma patients and is associated with increased mortality. The complexity and incomplete understanding of TIC have resulted in controversies regarding optimum management. This review aims to summarise the pathophysiology of TIC and appraise established and emerging advances in the management of TIC. METHODS: This narrative review is based on a literature search (MEDLINE database) completed in October 2020. Search terms used were "trauma induced coagulopathy", "coagulopathy of trauma", "trauma induced coagulopathy pathophysiology", "massive transfusion trauma induced coagulopathy", "viscoelastic assay trauma induced coagulopathy", "goal directed trauma induced coagulopathy and "fibrinogen trauma induced coagulopathy'. RESULTS: TIC is not a uniform phenotype but a spectrum ranging from thrombotic to bleeding phenotypes. Evidence for the management of TIC with tranexamic acid, massive transfusion protocols, viscoelastic haemostatic assays (VHAs), and coagulation factor and fibrinogen concentrates were evaluated. Although most trauma centres utilise fixed-ratio massive transfusion protocols, the "ideal" transfusion ratio of blood to blood products is still debated. While more centres are using VHAs to guide blood product replacement, there is no agreed VHA-based transfusion strategy. The use of VHA to quantify the functional contributions of individual components of coagulation may permit targeted treatment of TIC but remains controversial. CONCLUSION: A greater understanding of TIC, advances in point-of-care coagulation testing, and availability of coagulation factors and fibrinogen concentrates allows clinicians to employ a more goal-directed approach. Still, hospitals need to tailor their approaches according to available resources, provide training and establish local guidelines.

Preparing your intensive care unit for the COVID-19 pandemic: practical considerations and strategies.

The coronavirus disease 2019 (COVID-19) has rapidly evolved into a worldwide pandemic. Preparing intensive care units (ICU) is an integral part of any pandemic response. In this review, we discuss the key principles and strategies for ICU preparedness. We also describe our initial outbreak measures and share some of the challenges faced. To achieve sustainable ICU services, we propose the need to 1) prepare and implement rapid identification and isolation protocols, and a surge in ICU bed capacity; (2) provide a sustainable workforce with a focus on infection control; (3) ensure adequate supplies to equip ICUs and protect healthcare workers; and (4) maintain quality clinical management, as well as effective communication.

Preparing for a COVID-19 pandemic: a review of operating room outbreak response measures in a large tertiary hospital in Singapore.

The coronavirus disease 2019 (COVID-19) outbreak has been designated a public health emergency of international concern. To prepare for a pandemic, hospitals need a strategy to manage their space, staff, and supplies so that optimum care is provided to patients. In addition, infection prevention measures need to be implemented to reduce in-hospital transmission. In the operating room, these preparations involve multiple stakeholders and can present a significant challenge. Here, we describe the outbreak response measures of the anesthetic department staffing the largest (1,700-bed) academic tertiary level acute care hospital in Singapore (Singapore General Hospital) and a smaller regional hospital (Sengkang General Hospital). These include engineering controls such as identification and preparation of an isolation operating room, administrative measures such as modification of workflow and processes, introduction of personal protective equipment for staff, and formulation of clinical guidelines for anesthetic management. Simulation was valuable in evaluating the feasibility of new operating room set-ups or workflow. We also discuss how the hierarchy of controls can be used as a framework to plan the necessary measures during each phase of a pandemic, and review the evidence for the measures taken. These containment measures are necessary to optimize the quality of care provided to COVID-19 patients and to reduce the risk of viral transmission to other patients or healthcare workers.

RéSUMé: L'épidémie liée au coronavirus 2019 (COVID-19) a été qualifiée d'urgence de santé publique de portée internationale. La préparation face à une pandémie nécessite de la part d'un hôpital l'élaboration de stratégies pour gérer ses infrastructures, ses processus, son personnel et ses patients; il doit notamment instaurer des mesures de prévention des infections pour réduire la transmission intrahospitalière. Pour un bloc opératoire, ces préparations impliquent la participation de nombreux acteurs et peuvent constituer un véritable défi. Nous décrivons les mesures prises en réponse à l'épidémie par le département d'anesthésie qui sert le plus grand hôpital universitaire de soins aigus (1700 lits) de Singapour (Singapore General Hospital) et un plus petit hôpital régional (Sengkang General Hospital). Cela a été obtenu grâce à des expertises d'ingénierie, telles que l'identification et la préparation d'une salle d'opération en isolation, des mesures administratives telles que la modification du déroulement des activités et des processus, l'introduction d'équipements de protection individuels pour le personnel et ­ enfin ­ la formulation de lignes directrices cliniques pour la gestion anesthésique. La simulation a été importante pour évaluer la faisabilité de toutes nouvelles modifications des salles d'opération ou d'un nouveau flux de travail. Dans le contexte des différentes phases d'une pandémie, nous discutons de l'application d'une hiérarchie de contrôles comme cadre des modifications à chaque niveau de contrôle et nous passons aussi en revue les données probantes soutenant les mesures prises. Ces mesures de confinement sont nécessaires pour optimiser la qualité des soins procurés aux patients atteints de COVID-19 et pour réduire le risque de transmission du virus à d'autres patients ou employés du domaine de la santé.

Intubation of the patient with a suspected or confirmed COVID-19 infection.

We propose a set of recommendations from our clinical practice for intubation of the patient with a suspected or confirmed COVID-19 infection, with a goal to safely securing the airway while optimizing infection prevention practices to reduce the risk to healthcare personnel.

Skin-to-epidural distance in the Southeast Asian paediatric population: multiethnic morphometrics and international comparisons.

INTRODUCTION: Paediatric epidurals can present technical challenges due to wide variations in age and weight among children, ranging from neonates to teenagers. This study evaluated the skin-to-epidural distance in the thoracic and lumbar regions to determine the relationship between age, weight and ethnicity and depth to the epidural space in our Singapore paediatric population. METHODS: Data from the Acute Pain Service was prospectively collected over 16 years. Details included patient demographics, level of epidural performed and distance from skin to epidural space. Multivariable regression analysis was performed to determine the association of weight, age, ethnicity and gender with the depths to the thoracic and lumbar epidural spaces. A simple linear regression was calculated to predict the depth to both thoracic and lumbar epidural spaces based on body weight. Equations were formulated to describe the relationship between weight and depth of epidural space. RESULTS: A total of 616 midline epidurals were studied. Regression analysis was performed for 225 thoracic epidurals and 363 lumbar epidurals. Our study revealed a clear correlation between skin-to-lumbar epidural distance and weight in children. The best correlation was demonstrated between skin-to-lumbar epidural distance and body weight (R2 = 0.729). This relationship was described by the formula: depth (mm) = (0.63 × weight [kg]) + 9.2. CONCLUSION: Skin-to-lumbar epidural distance correlated with weight in children. Our results highlighted the clinical significance of differences between Southeast Asian paediatric populations when compared to other populations.

Fibreoptic intubation in airway management: a review article.

Since the first use of the flexible fibreoptic bronchoscope, a plethora of new airway equipment has become available. It is essential for clinicians to understand the role and limitations of the available equipment to make appropriate choices. The recent 4th National Audit Project conducted in the United Kingdom found that poor judgement with inappropriate choice of equipment was a contributory factor in airway morbidity and mortality. Given the many modern airway adjuncts that are available, we aimed to define the role of flexible fibreoptic intubation in decision-making and management of anticipated and unanticipated difficult airways. We also reviewed the recent literature regarding the role of flexible fibreoptic intubation in specific patient groups who may present with difficult intubation, and concluded that the flexible fibrescope maintains its important role in difficult airway management.

An Audit of 829 Paediatric Epidurals in a Tertiary Singapore Hospital: Complications and Conundrums.

INTRODUCTION: The incidence of complications related to epidural analgesia remains less well defined in the paediatric population as compared to adults. A retrospective review of prospectively collected data was performed to review and quantify risks of both adverse events and complications related to epidural analgesia in our Singaporean paediatric population. MATERIALS AND METHODS: Data from the Acute Pain Service (APS) was prospectively collected over 19 years. Details included the age of the patients, level of insertion of the epidural catheter, number of attempts, staff grade of the practitioner, adverse events and complications. RESULTS: Collectively, 829 epidurals were performed from 1 June 1997 to 31 May 2016. No deaths or major complications occurred within the 16-year period. There were 5 instances of dural puncture (0.6%). The incidence of minor postoperative complications was 3.1% with the majority of postoperative events comprising catheter-related problems (n = 161, 22.4%). Prolonged use of the catheter beyond 3 days is associated with a statistically significant increase in the frequency of skin infective/ inflammatory changes (P <0.01). We highlight common complications and conundrums faced. CONCLUSION: Epidural analgesia has been shown to be associated with a relatively low risk of complications both in the adult and paediatric populations, albeit with a fourfold increased risk in the latter cohort. Adverse events reported are largely related to catheter problems and have minimal impact upon the patient.

Anaesthetic management of acute airway obstruction.

The acutely obstructed airway is a medical emergency that can potentially result in serious morbidity and mortality. Apart from the latest advancements in anaesthetic techniques, equipment and drugs, publications relevant to our topic, including the United Kingdom's 4th National Audit Project on major airway complications in 2011 and the updated American Society of Anesthesiologists' difficult airway algorithm of 2013, have recently been published. The former contained many reports of adverse events associated with the management of acute airway obstruction. By analysing the data and concepts from these two publications, this review article provides an update on management techniques for the acutely obstructed airway. We discuss the principles and factors relevant to the decision-making process in formulating a logical management plan.
