RESUMO

Despite a lack of clinical data demonstrating the effectiveness of alcohol swab cleansing prior to vaccinations as a prophylactic measure to prevent skin infections, it is recommended for vaccine administration by the Canadian Immunization Guide. The objective of this study was to evaluate the risk of adverse events after omitting alcohol skin cleansing in long-term care (LTC) residents receiving vaccinations during the COVID-19 pandemic. Two medium-sized LTC homes participated in a cohort study, whereby one LTC used alcohol swab cleansing prior to resident vaccinations and the other did not. All residents received two doses of the BNT162b2 COVID-19 vaccine separated by an average (SD) 29.3 (8.5) days. The electronic chart records of participants were reviewed by researchers blinded to group allocation to assess for the presence of adverse events following immunization (AEFI), including reactogenicity, cellulitis, abscess, or systemic reactions. Log-binomial regression was used to compute risk ratios (with 95% confidence intervals) of an AEFI according to alcohol swab status. 189 residents were included, with a total of 56 AEFI between the two doses. The risk of reactogenicity (adjusted RR 0.54, 95% CI 0.17-1.73) or systemic reactions (adjusted RR 0.75, 95% CI 0.26-2.13) did not differ for the residents that received alcohol skin antisepsis compared to those that did not. There were no cases of cellulitis or abscess. This study did not demonstrate an elevated risk of AEFI in LTC residents receiving two doses of the BNT162b2 mRNA COVID vaccine without alcohol skin antisepsis.

RESUMO

Background: Prolonged QT interval (QTc) can be a serious adverse event from SARS-CoV-2 infection and associated treatment, including remdesivir. Methods: We present a case of a 55-year-old woman with COVID-19 pneumonia who was treated with remdesivir. The QTc on admission was 483 ms. After three doses of remdesivir, she had an episode of non-sustained ventricular tachycardia. Repeat QTc was significantly prolonged at 609 ms. She experienced a polymorphic ventricular tachycardic cardiac arrest the next morning, thought to be secondary to torsades de pointes. Results: Transthoracic echocardiogram showed normal biventricular function. Electrolytes were within normal limits. In the absence of other QTc-prolonging medications, remdesivir was thought to be inciting agent. Following discontinuation of remdesivir, the patient's QTc returned to baseline. Conclusions: There is a risk for cardiac events from QTc prolongation effects of SARS-CoV-2 infection and associated treatment. We recommend pharmacological profile review and cardiac monitoring for patients receiving remdesivir.


Historique: Un intervalle QT prolongé (QTc) peut être un grave effet indésirable de l'infection par le SRAS-CoV-2 et du traitement qui s'y associe, y compris le remdésivir. Méthodologie: Les chercheurs présentent le cas d'une femme de 55 ans atteinte d'une pneumonie à COVID-19 qui a reçu un traitement au remdésivir. Son QTc à l'admission était de 483 ms. Après trois doses de remdésivir, elle a subi un épisode de tachycardie ventriculaire non soutenue. La reprise du QTc était particulièrement prolongé, à 609 ms. La patiente a vécu un arrêt cardiaque causé par une tachycardie ventriculaire polymorphe le lendemain matin, considéré comme secondaire à des torsades de pointe. Résultats: L'échocardiogramme transthoracique a révélé une fonction biventriculaire normale. Les électrolytes se situaient dans les limites normales. En l'absence d'autres médicaments pour prolonger le QTc, le remdésivir a été présumé comme responsable. Après l'arrêt de ce médicament, le QTc de la patiente est redevenu normal. Conclusions: La prolongation du QTc découlant de l'infection par le SRAS-CoV-2 et du traitement qui s'y associe entraîne un risque d'arrêt cardiaque. Il est recommandé de procéder à une évaluation du profil pharmacologique et d'assurer la surveillance cardiaque des patients qui reçoivent du remdésivir.

RESUMO

Objectives: CARD (comfort, ask, relax, distract) is a vaccine delivery framework that includes interventions to improve the patient's experience. CARD has not been previously implemented in long-term care (LTC) settings. This study evaluated drivers to implementation for COVID-19 vaccinations in an LTC facility. Methods: Postimplementation interpretive evaluation including qualitative interviews and quantitative surveys with eight participants. The Consolidated Framework for Implementation Research (CFIR) was used for analysis. Adverse reactions to vaccinations and CARD interventions, including local reactogenicity and systemic reactions, were abstracted from medical charts of residents. Results: Eight CFIR constructs emerged. Staff perceived CARD was complex because it added steps to vaccination delivery. Motivated to meet residents' needs, a receptive implementation climate of support among staff led to using strategies within CARD, such as administering topical anesthetics and omitting alcohol skin antisepsis prior to injections. Having an effective network like the residents council positively influenced implementation by allowing residents to voice their opinions. Facilitators to implementation included staff knowledge and beliefs and staff's commitment to their organization, which was focused on person-centered care. Barriers included lack of available resources (inadequate staffing), insufficient communication between management and staff and lack of awareness of CARD, and external policies not aligned with CARD. Chart reviews conducted for 93 vaccinated residents corroborated perceptions of vaccination and CARD intervention safety, revealing a low rate of local and systemic adverse reactions and no cases of skin infection. Discussion: We identified positive and negative implementation drivers. Future research is recommended to expand the strategies employed and involve residents more directly.


Objectifs: Le système CARD (confort, aide, relaxation, distraction) est un cadre d'administration de vaccins qui comprend des interventions pour amèliorer l'expérience du patient. Le système CARD n'a pas été mis en œuvre précédemment dans les établissements de soins de longue durée. Cette étude a évalué les facteurs de sa mise en œuvre pour la vaccination contre la COVID-19 dans un établissement de soins de longue durée.Méthodes: Évaluation interprétative après la mise en œuvre, y compris des entretiens qualitatifs et des enquêtes quantitatives auprès de huit participants. Le Cadre consolidé pour la recherche sur la mise en œuvre (CFIR) a été utilisé pour l'analyse. Les effets indésirables à la vaccination et aux interventions CARD, y compris la réactogénicité locale et les réactions systémiques, ont été extraites des dossiers médicaux des résidentsRésultats: Huit construits du CFIR ont émergé. Le personnel a perçu que le système CARD était complexe car il ajoutait des étapes à la vaccination. Motivé à répondre aux besoins des résidents, un climat de mise en œuvre réceptif suscitant le soutien du personnel a conduit à l'utilisation de stratégies propres au système CARD, telles que l'administration d'anesthésiques topiques et l'omission de l'antisepsie cutanée à l'alcool avant les injections. Le fait d'avoir un réseau efficace comme le conseil des résidents a influencé positivement la mise en œuvre en permettant à ces derniers d'exprimer leurs opinions. Les facilitateurs de la mise en œuvre comprenaient les connaissances et les croyances du personnel et l'engagement de celui-ci envers l'organisation, qui mettait l'accent sur les soins centrés sur la personne. Les obstacles comprenaient le manque de disponibilité des ressources (effectifs insuffisants), l'insuffisance de la communication entre la direction et le personnel et le manque de connaissances au sujet de CARD, de même que les politiques externes non alignées avec le système CARD. Un examen des dossiers effectué pour 93 résidents vaccinés a corroboré les perceptions de la sécurité de la vaccination et de l'intervention CARD tout en révélant un faible taux d'effets indésirables locaux et systémiques et aucun cas d'infection cutanée.Discussion: Nous avons identifié des facteurs de mise en œuvre positifs et négatifs. Des recherches futures sont recommandées pour élargir les stratégies utilisées et impliquer plus directement les résidents.

RESUMO

OBJECTIVE: Infectious diseases, including pneumonia, malaria, and diarrheal diseases, are the leading causes of death in children younger than 5 years worldwide. The vast majority of these deaths occur in resource-limited settings where there is significant variation in the availability and type of human, physical, and infrastructural resources. The ability to identity gaps in healthcare systems that may hinder their ability to deliver care is an important step to determining specific interventions for quality improvement. Our study objective was to develop a comprehensive, digital, open-access health facility survey to assess facility readiness to provide pediatric critical care in resource-limited settings (eg, low- and lower middle-income countries). METHODS: A literature review of existing facility assessment tools and global guidelines was conducted to generate a database of survey questions. These were then mapped to one of the following 8 domains: hospital statistics, services offered, operational flow, facility infrastructure, staff and training, medicines and equipment, diagnostic capacity, and quality of clinical care. A 2-phase survey was developed and an iterative review process of the survey was undertaken with 12 experts based in low- and middle-income countries. This was built into the REDCap Mobile Application for electronic data capture. RESULTS: The literature review process yielded 7 facility assessment tools and 7 global guidelines for inclusion. After the iterative review process, the final survey consisted of 11 sections with 457 unique questions in the first phase, "environmental scan," focusing on the infrastructure, availability, and functionality of resources, and 3 sections with 131 unique questions in the second phase, "observation scan," focusing on the level of clinical competency. CONCLUSIONS: A comprehensive 2-phase survey was created to evaluate facility readiness for pediatric critical care. Results will assist hospital administrators and policymakers to determine priority areas for quality improvement, enabling them to implement a Plan-Do-Study-Act cycle to improve care for the critically ill child.

RESUMO

BACKGROUND: Pediatric intensive care relies on having experienced and effective transport systems to transfer critically ill children to the appropriate centre for care. Our aim was to compare hospital outcomes among children admitted directly to a pediatric intensive care unit (PICU) with those of children transferred from another facility. METHODS: We conducted a descriptive study using electronic medical records and the PICU database from the BC Children's Hospital. Patients admitted to the PICU from January 2015 to December 2017 were included. We excluded patients who were admitted electively, were admitted for recovery postoperatively, or had inconsistent or out-of-range addresses. We compared hospital mortality rates, use of mechanical ventilation within 24 hours of admission and length of PICU stay between children admitted directly from the BC Children's Hospital emergency department and those transferred from a referring institution. RESULTS: During the study period, there were 870 unique admissions comprising 386 direct admissions and 484 transferred patients. Transported patients were younger, were more critically ill on presentation and required longer stays. The proportions of children who died and of children who required mechanical ventilation within 24 hours of admission were higher in the transported group than in the group admitted directly from the emergency department (8.3% v. 3.9%, p = 0.008, and 75.8% v. 58.0%, p < 0.001, respectively). INTERPRETATION: Mortality rate and use of intensive care resources were higher among children who were transported. Further research is needed to examine the key factors driving the differences in outcomes, including the severity of illness on first presentation, transport team composition, and transport distance and duration.

RESUMO

Sepsis is a life-threatening dysfunction of the immune system leading to multiorgan failure that is precipitated by infectious diseases and is a leading cause of death in children under 5 years of age. It is necessary to be able to identify a sick child at risk of developing sepsis at the earliest point of presentation to a healthcare facility so that appropriate care can be provided as soon as possible. Our study objective was to generate a list of consensus-driven predictor variables for the derivation of a prediction model that will be incorporated into a mobile device and operated by low-skilled healthcare workers at triage. By conducting a systematic literature review and examination of global guideline documents, a list of 72 initial candidate predictor variables was generated. A two-round modified Delphi process involving 26 experts from both resource-rich and resource-limited settings, who were also encouraged to suggest new variables, yielded a final list of 45 predictor variables after evaluating each variable based on three domains: predictive potential, measurement reliability, and level of training and resources required. The final list of predictor variables will be used to collect data and contribute to the derivation of a prediction model.

RESUMO

Spinal mGluR5 is a key mediator of neuroplasticity underlying persistent pain. Although brain mGluR5 is localized on cell surface and intracellular membranes, neither the presence nor physiological role of spinal intracellular mGluR5 is established. Here we show that in spinal dorsal horn neurons >80% of mGluR5 is intracellular, of which ∼60% is located on nuclear membranes, where activation leads to sustained Ca(2+) responses. Nerve injury inducing nociceptive hypersensitivity also increases the expression of nuclear mGluR5 and receptor-mediated phosphorylated-ERK1/2, Arc/Arg3.1 and c-fos. Spinal blockade of intracellular mGluR5 reduces neuropathic pain behaviours and signalling molecules, whereas blockade of cell-surface mGluR5 has little effect. Decreasing intracellular glutamate via blocking EAAT-3, mimics the effects of intracellular mGluR5 antagonism. These findings show a direct link between an intracellular GPCR and behavioural expression in vivo. Blockade of intracellular mGluR5 represents a new strategy for the development of effective therapies for persistent pain.
