RESUMEN

Chronic hepatitis C (HCV) in women of childbearing age is a major public health concern with ∼15 million women aged 15-49 years living with HCV globally in 2019. Evidence suggests HCV in pregnancy is associated with adverse pregnancy and infant outcomes. This includes ∼6% risk of infants acquiring HCV vertically, and this is the leading cause of HCV in children globally. However, few countries offer routine universal antenatal HCV screening, and direct-acting antivirals (DAAs) are not approved for pregnant or breastfeeding women although small clinical trials are ongoing. We conducted a survey of pregnant and postpartum women in 3 high HCV burden lower-middle-income countries to assess the acceptability of universal antenatal HCV screening and DAA treatment in the scenario that DAAs are approved for use in pregnancy. Pregnant and postpartum women attending antenatal clinics in Egypt, Pakistan, and Ukraine were invited to complete a survey and provide demographic and clinical data on their HCV status. Among the 630 women included (n=210 per country), 73% were pregnant and 27% postpartum, 27% were ever HCV antibody or PCR positive. Overall, 586 (93%) reported acceptability of universal antenatal HCV screening and 544 (88%) would take DAAs in pregnancy (92%, 98%, and 73% in Egypt, Pakistan, and Ukraine, respectively). Most said they would take DAAs in pregnancy to prevent vertical acquisition and other risks for the baby, and a smaller proportion would take DAAs for maternal cure. Our findings suggest that should DAAs be approved for use in pregnancy, the uptake of both HCV screening and DAA treatment may be high in women living in lower-middle-income countries.

RESUMEN

BACKGROUND: Healthcare workplace mistreatment has been documented globally. Poor workplace behaviour, ranging from incivility to bullying and harassment, is common in healthcare, and contributes significantly to adverse events in healthcare, poor mental health among healthcare workers, and to attrition in the healthcare workforce, particularly in junior years. Poor workplace behaviour is often normalised, and is difficult to address. Verbatim theatre, a form of research informed theatre in which plays are created from informants' exact words only, is particularly suited to facilitating workplace culture change by raising awareness about issues that are difficult to discuss. The objective of this study was to assess the impact of the verbatim theatre play 'Grace Under Pressure' on workplace culture in NSW hospitals. METHODS: The intervention was conducted in 13 hospitals from 8 Local Health Districts (LHDs) in NSW, Australia, in October and November 2019, with aggregated impact across all sites measured by a bespoke survey ('Pam McLean Centre (PMC) survey') at the conclusion of the intervention. This study was conducted in 3 Local Health Districts (one urban, one regional, one remote), with data collection conducted in November-December 2019 and December 2020. The study design was a mixed methods assessment of the play's impact using (1) validated baseline measures of psychosocial risk, analysed descriptively, (2) overall findings from the PMC survey above, analysed descriptively, (3) interviews conducted within a month of the intervention, analysed thematically and (4) interviews conducted one year later, analysed thematically. RESULTS: Half (51.5%) of the respondents (n = 149) to the baseline survey had scores indicating high risk of job strain and depressive symptoms. Of 478 respondents to the PMC survey (response rate 57%), 93% found the play important, 92% recommended others see the play, 89% considered that it stimulated thinking about workplace behaviour, and 85% that it made discussing these issues easier. Thematic analysis of interviews within one month (n = 21) showed that the play raised awareness about poor workplace behaviour and motivated behaviour change. Interviews conducted one year later (n = 6) attributed improved workplace culture to the intervention due to improved awareness, discussion and capacity to respond to challenging issues. CONCLUSIONS: Verbatim theatre is effective in raising awareness about difficult workplace behaviour in ways that motivate behaviour change, and hence can be effective in catalysing real improvements in healthcare workplace culture. Creative approaches are recommended for addressing similarly complex challenges in healthcare workforce retention.

RESUMEN

PURPOSE: Children who require specialist outpatient care typically wait substantial periods during which their condition may progress, making treatment more difficult and costly. Timely and effective therapy during this period may reduce the need for lengthy specialist care. This study evaluated the cost-effectiveness of an individualized, evidence-informed, web-based program for children with urinary incontinence awaiting a specialist appointment (eADVICE) compared to usual care. eADVICE was supervised by a primary physician and delivered by an embodied conversational agent (ECA). MATERIALS AND METHODS: A trial-based cost-effectiveness analysis was performed from the perspective of the healthcare funder as a sub-study of eADVICE, a multicenter waitlist-controlled randomized trial. Outcomes measures were incremental cost per incremental change in continence status and quality of life on an intention-to-treat basis. Uncertainty was examined using cost-effectiveness planes, scenarios, and 1-way sensitivity analyses. Costs were valued in 2021 Australian dollars ($). RESULTS: The use of eADVICE was found to be cost-saving and beneficial (dominant) over usual care, with a higher proportion of children dry over 14 days at 6 months (RD 0.13; 95%CI 0.02-0.23, P = .03) and mean healthcare costs reduced by $188 (95%CI $61-$315) per participant. CONCLUSION: An individualized, evidence-informed web-based program delivered by an ECA is likely cost-saving for children with urinary incontinence awaiting a specialist appointment. The potential economic impact of such a program is favorable and substantial and may be transferable to outpatient clinic settings for other chronic health conditions.

RESUMEN

BACKGROUND: Cardiovascular disease (CVD) represents the greatest burden of mortality worldwide, and statins are the most commonly prescribed drug in its management. A wealth of information pertaining to statins and their side effects is on the internet; however, to date, no assessment of the accuracy, credibility, and readability of this information has been undertaken. OBJECTIVE: This study aimed to evaluate the quality (accuracy, credibility, and readability) of websites likely to be visited by the general public undertaking a Google search of the side effects and use of statin medications. METHODS: Following a Google web search, we reviewed the top 20 consumer-focused websites with statin information. Website accuracy, credibility, and readability were assessed based on website category (commercial, not-for-profit, and media), website rank, and the presence or absence of the Health on the Net Code of Conduct (HONcode) seal. Accuracy and credibility were assessed following the development of checklists (with 20 and 13 items, respectively). Readability was assessed using the Simple Measure of Gobbledegook scores. RESULTS: Overall, the accuracy score was low (mean 14.35 out of 20). While side effects were comprehensively covered by 18 websites, there was little information about statin use in primary and secondary prevention. None of the websites met all criteria on the credibility checklist (mean 7.8 out of 13). The median Simple Measure of Gobbledegook score was 9.65 (IQR 8.825-10.85), with none of the websites meeting the recommended reading grade of 6, even the media websites. A website bearing the HONcode seal did not mean that the website was more comprehensive or readable. CONCLUSIONS: The quality of statin-related websites tended to be poor. Although the information contained was accurate, it was not comprehensive and was presented at a reading level that was too difficult for an average reader to fully comprehend. As such, consumers risk being uninformed about this pharmacotherapy.

RESUMEN

Ethanol is the psychoactive substance identified most frequently in post-mortem specimens. Unfortunately, interpreting post-mortem ethanol concentrations can be difficult because of post-mortem alcohol redistribution and the possibility of post-mortem alcohol neogenesis. Indeed, in the time interval between death and sample collection, the decedent may be exposed to non-controlled environments for an extended period, promoting microbial colonization. Many authors report that in the presence of carbohydrates and other biomolecules, various species of bacteria, yeast, and fungi can synthesize ethanol and other volatile substances in vitro and in vivo. The aim of this study was to study the impact of several variables on microbial ethanol production as well as develop a mathematical model that could estimate the microbial-produced ethanol in correlation with the most significant consensual produced higher alcohol, 1-propanol. An experimental setup was developed using human blood samples and cadaveric fragments incubated under strictly anaerobic conditions to produce a novel substrate, "cadaveric putrefactive blood" mimicking post-mortem corpse conditions. The samples were analyzed daily for ethanol and 1-propanol using an HS-GC-FID validated method. The formation of ethanol was evaluated considering different parameters such as putrefactive stage, blood glucose concentration, storage temperature, and storage time. Statistical analysis was performed using the Mann-Whitney non-parametric test and simple linear regression. The results indicate that the early putrefactive stage, high blood glucose concentration, high temperature, and time of incubation increase microbial ethanol production. In addition, the developed mathematical equation confirms the feasibility of using 1-propanol as a marker of post-mortem ethanol production.

RESUMEN

The neuron-specific K+/Cl- co-transporter 2, KCC2, which is critical for brain development, regulates γ-aminobutyric acid-dependent inhibitory neurotransmission. Consistent with its function, mutations in KCC2 are linked to neurodevelopmental disorders, including epilepsy, schizophrenia, and autism. KCC2 possesses 12 transmembrane spans and forms an intertwined dimer. Based on its complex architecture and function, reduced cell surface expression and/or activity have been reported when select disease-associated mutations are present in the gene encoding the protein, SLC12A5. These data suggest that KCC2 might be inherently unstable, as seen for other complex polytopic ion channels, thus making it susceptible to cellular quality control pathways that degrade misfolded proteins. To test these hypotheses, we examined KCC2 stability and/or maturation in five model systems: yeast, HEK293 cells, primary rat neurons, and rat and human brain synaptosomes. Although studies in yeast revealed that KCC2 is selected for endoplasmic reticulum-associated degradation (ERAD), experiments in HEK293 cells supported a more subtle role for ERAD in maintaining steady-state levels of KCC2. Nevertheless, this system allowed for an analysis of KCC2 glycosylation in the ER and Golgi, which serves as a read-out for transport through the secretory pathway. In turn, KCC2 was remarkably stable in primary rat neurons, suggesting that KCC2 folds efficiently in more native systems. Consistent with these data, the mature glycosylated form of KCC2 was abundant in primary rat neurons as well as in rat and human brain. Together, this work details the first insights into the influence that the cellular and membrane environments have on several fundamental KCC2 properties, acknowledges the advantages and disadvantages of each system, and helps set the stage for future experiments to assess KCC2 in a normal or disease setting.

RESUMEN

BACKGROUND: Xylazine is a dangerous veterinary sedative found mainly in illicit fentanyl in the Northeast and Midwest. Its role in the Deep South overdose crisis is not well-characterized. METHODS: We conducted a retrospective review of autopsy data in Jefferson County, Alabama to identify trends in xylazine prevalence among people who fatally overdosed from June 2019 through June 2023. RESULTS: 165 decedents met inclusion criteria. While the first identified xylazine-associated overdose was in June 2019, xylazine has become consistently prevalent since January 2021. All cases of xylazine-associated fatal overdoses were accompanied by fentanyl, and most (75.4%) involved poly-drug stimulant use. The average age was 42.2, and most decedents were white (58.8%) and male (68.5%). Overall, 18.2% of people were unhoused at the time of death. DISCUSSION: Xylazine is prevalent in the Deep South. Efforts to promote harm reduction, publicly viewable drug supply trends, and legalization of drug checking and syringe service programs should be prioritized.

RESUMEN

Cardiovascular homeostasis is maintained, in part, by neural signals arising from arterial baroreceptors that apprise the brain of blood volume and pressure. Here, we test whether neurons within the nodose ganglia that express angiotensin type-1a receptors (referred to as NGAT1aR) serve as baroreceptors that differentially influence blood pressure (BP) in male and female mice. Using Agtr1a-Cre mice and Cre-dependent AAVs to direct tdTomato to NGAT1aR, neuroanatomical studies revealed that NGAT1aR receive input from the aortic arch, project to the caudal nucleus of the solitary tract (NTS), and synthesize mechanosensitive ion channels, Piezo1/2 To evaluate the functionality of NGAT1aR, we directed the fluorescent calcium indicator (GCaMP6s) or the light-sensitive channelrhodopsin-2 (ChR2) to Agtr1a-containing neurons. Two-photon intravital imaging in Agtr1a-GCaMP6s mice revealed that NGAT1aR couple their firing to elevated BP, induced by phenylephrine (i.v.). Furthermore, optical excitation of NGAT1aR at their soma or axon terminals within the caudal NTS of Agtr1a-ChR2 mice elicited robust frequency-dependent decreases in BP and heart rate, indicating that NGAT1aR are sufficient to elicit appropriate compensatory responses to vascular mechanosensation. Optical excitation also elicited hypotensive and bradycardic responses in ChR2-expressing mice that were subjected to deoxycorticosterone acetate (DOCA)-salt hypertension; however, the duration of these effects was altered, suggestive of hypertension-induced impairment of the baroreflex. Similarly, increased GCaMP6s fluorescence observed after administration of phenylephrine was delayed in mice subjected to DOCA-salt or chronic delivery of angiotensin II. Collectively, these results reveal the structure and function of NGAT1aR and suggest that such neurons may be exploited to discern and relieve hypertension.

RESUMEN

OBJECTIVE: Since the U.S. Supreme Court eliminated the federal right to abortion, there is a heightened need to understand public opinion about the criminalization of people who attempt to end their pregnancies outside the formal healthcare setting, referred to as self-managed abortion (SMA). We assessed U.S. attitudes about whether three forms of SMA should be legal, reported or punished: 1) using abortion pills obtained outside the healthcare system, 2) using other medications, drugs, herbs, or by drinking alcohol, and 3) using traumatic methods (inserting an object in their body or hitting their stomach). METHODS: From December 2021 to January 2022, we administered a national probability-based online survey to English- and Spanish-speaking people assigned female (AFAB, ages 15-49) or male at birth (AMAB, ages 18-49) regarding their attitudes about criminalizing SMA, using Ipsos' KnowledgePanel. We estimated weighted proportions and conducted multivariable regression analyses to identify characteristics associated with support for SMA legality and punishment (reporting to authorities, paying a fine or going to jail). RESULTS: A total of 7,016 AFAB and 360 AMAB completed the survey. People were less likely (p < .05) to agree that SMA using abortion pills should be illegal (34% of AFAB and 43% of AMAB) than other forms of SMA (36-48%), although over one-fifth were unsure (AFAB, 20-23% and AMAB, 24-27%). People were less likely to agree SMA using abortion pills should be criminalized than SMA using other drugs, medications, herbs, alcohol or by using traumatic methods. In multivariable analyses, AMAB and Christian religion were associated with agreeing that SMA using abortion pills should be illegal; people who identified as Hispanic/Latinx ethnicity and experienced medical mistreatment were less likely to agree SMA with medication abortion pills should be illegal. CONCLUSIONS: Public support for criminalizing SMA is complex and varied by SMA method and form of punishment.

RESUMEN

BACKGROUND: Systematic reviews provide the highest level of evidence about a topic. Ten-week workshops in conducting systematic reviews were held with hospital doctors in 2019 and 2020. AIM: This study analysed participants' feedback about the systematic review workshops to improve how we teach clinicians about conducting systematic reviews. METHODS: Attendees completed a post-workshop survey (with multiple-choice and free-text items) to assess knowledge and skills gained. We compared the responses of senior and junior doctors. We used descriptive statistics for the quantitative data and compared groups using Χ2 testing. Qualitative data were analysed using conceptual content analysis. RESULTS: Of 81 attendees, 52% completed the survey. Of those, 69% had no prior experience with systematic reviews, 93% reported increased knowledge and ability to conduct research and 69% reported increased ability to conduct systematic reviews. More senior than junior clinicians reported gaining knowledge about writing and publishing (37% vs 11%, P = 0.047) and making greater use of skills gained to conduct research (56% vs 23%, P = 0.029). Five themes were identified: learning through course structure; learning through course organisation; teaching style; flexible learning; and suggestions for progression and improvement. Respondents suggested running the workshops during protected teaching time, more time for some sessions, conducting the workshop series more often and making clinicians aware of the workshop series at hospital orientation. CONCLUSION: The skills learnt from the systematic review workshop series impacted not only participants' research knowledge and skills, and plans to conduct future research, but also facilitated looking up medical literature in daily clinical work, supporting evidence-based clinical practice.

RESUMEN

PURPOSE: Children referred to specialist outpatient clinics by primary care providers often have long waiting times before being seen. We assessed whether an individualized, web-based, evidence-informed management support for children with urinary incontinence while waiting reduced requests for specialist appointments. MATERIALS AND METHODS: A multicenter, waitlisted randomized controlled trial was conducted for children (5-18 years) with urinary incontinence referred to tertiary pediatric continence clinics. Participants were randomized to the web-based eHealth program electronic Advice and Diagnosis Via the Internet following Computerized Evaluation (eADVICE), which used an embodied conversational agent to engage with the child at the time of referral (intervention) or 6 months later (control). The primary outcome was the proportion of participants requesting a clinic appointment at 6 months. Secondary outcomes included persistent incontinence, and the Paediatric incontinence Questionnaire (PinQ) score. RESULTS: From 2018 to 2020, 239 children enrolled, with 120 randomized to eADVICE and 119 to the control arm. At baseline, participants' mean age was 8.8 years (SD 2.2), 62% were males, mean PinQ score was 5.3 (SD 2.2), 36% had daytime incontinence, and 97% had nocturnal enuresis. At 6 months, 78% of eADVICE participants vs 84% of controls requested a clinic visit (relative risk 0.92, 95% CI 0.79, 1.06, P = .3), and 23% eADVICE participants vs 10% controls were completely dry (relative risk 2.23, 95% CI 1.10, 4.50, P = .03). The adjusted mean PinQ score was 3.5 for eADVICE and 3.9 for controls (MD -0.37, 95% CI -0.71, -0.03, P = .03). CONCLUSIONS: The eADVICE eHealth program for children awaiting specialist appointments doubled the proportion who were dry at 6 months and improved quality of life but did not reduce clinic appointment requests.

RESUMEN

Recent years have seen the development of high-accuracy and high-throughput genetic manipulation techniques, which have greatly improved our understanding of genetically tractable microbes. However, challenges remain in establishing genetic manipulation techniques in novel organisms, owing largely to exogenous DNA defence mechanisms, lack of selectable markers, lack of efficient methods to introduce exogenous DNA and an inability of genetic vectors to replicate in their new host. In this review, we describe some of the techniques that are available for genetic manipulation of novel microorganisms. While many reviews exist that focus on the final step in genetic manipulation, the editing of recipient DNA, we particularly focus on the first step in this process, the transfer of exogenous DNA into a strain of interest. Examples illustrating the use of these techniques are provided for a selection of human gut bacteria in which genetic tractability has been established, such as Bifidobacterium, Bacteroides and Roseburia. Ultimately, this review aims to provide an information source for researchers interested in developing genetic manipulation techniques for novel bacterial strains, particularly those of the human gut microbiota.

RESUMEN

Three-dimensional (3D) printing is increasingly used in medical education and paediatric cardiology. A technology-enhanced learning (TEL) module was designed to accompany 3D printed models of congenital heart disease (CHD) to aid in the teaching of medical students. There are few studies evaluating the attitudes and perceptions of medical students regarding their experience of learning about CHD using 3D printing. This study aimed to explore senior medical students' experiences in learning about paediatric cardiology through a workshop involving 3D printed models of CHD supported by TEL in the form of online case-based learning. A mixed-methods evaluation was undertaken involving a post-workshop questionnaire (n = 94 students), and focus groups (n = 16 students). Focus group and free-text questionnaire responses underwent thematic analysis. Questionnaire responses demonstrated widespread user satisfaction; 91 (97%) students agreed that the workshop was a valuable experience. The highest-level satisfaction was for the physical 3D printed models, the clinical case-based learning, and opportunity for peer collaboration. Thematic analysis identified five key themes: a variable experience of prior learning, interplay between physical and online models, flexible and novel workshop structure, workshop supported the learning outcomes, and future opportunities for learning using 3D printing. A key novel finding was that students indicated the module increased their confidence to teach others about CHD and recommended expansion to other parts of the curriculum. 3D printed models of CHD are a valuable learning resource and contribute to the richness and enjoyment of medical student learning, with widespread satisfaction. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-023-01840-w.

RESUMEN

BACKGROUND: Volunteering is a form of prosocial behaviour that has a been recognised as having positive benefits for medical students. However, there is a lack of research on what influences students to volunteer during and after weather-related disasters. Our study (1) explores factors related to medical students' willingness and readiness to volunteer, and (2) describes mental health impacts of the flood events on students. METHODS: We conducted a mixed-methods study of medical students on rural clinical placements in a regional area of Australia, 2 to 6 weeks after two major flooding events in 2022. Data were collected through survey and focus groups. Summary statistics were generated from the survey data, and Fisher's exact test was used to determine associations between student experience of the flood and self-rated well-being. Qualitative data were deductively analysed using Byrne and colleagues' theory of prosocial behaviour during an emergency. RESULTS: The 36 students who participated in focus groups (including the 34 who completed the survey) (response rates 84% and 79%, respectively) demonstrated high levels of prosocial behaviours and were willing to volunteer. A sense of moral obligation was the primary reason for volunteering, whereas concerns for their physical and psychological safety, and missing key aspects of their training, were the strongest reasons for not continuing to volunteer. Students reported personal stress, anxiety and trauma during this period, with significant associations between self-rated impacts on their well-being and feelings of being terrified, helpless and hopeless during the flooding events and of still being distressed weeks later (p < .05). CONCLUSIONS: This study expands on prosocial behaviour theory by applying Byrne and colleagues elaborated model in the context of medical student volunteering during the 2022 major flooding events in Australia. Modifiable barriers to prosocial behaviour are identified along with proposed strategies to address these barriers.

RESUMEN

Copper is an essential enzyme cofactor in oxidative metabolism, anti-oxidant defenses, and neurotransmitter synthesis. However, intracellular copper, when improperly buffered, can also lead to cell death. Given the growing interest in the use of copper in the presence of the ionophore elesclomol (CuES) for the treatment of gliomas, we investigated the effect of this compound on the surround parenchyma-namely neurons and astrocytes in vitro. Here, we show that astrocytes were highly sensitive to CuES toxicity while neurons were surprisingly resistant, a vulnerability profile that is opposite of what has been described for zinc and other toxins. Bolstering these findings, a human astrocytic cell line was similarly sensitive to CuES. Modifications of cellular metabolic pathways implicated in cuproptosis, a form of copper-regulated cell death, such as inhibition of mitochondrial respiration or knock-down of ferredoxin 1 (FDX1), did not block CuES toxicity to astrocytes. CuES toxicity was also unaffected by inhibitors of apoptosis, necrosis or ferroptosis. However, we did detect the presence of lipid peroxidation products in CuES-treated astrocytes, indicating that oxidative stress is a mediator of CuES-induced glial toxicity. Indeed, treatment with anti-oxidants mitigated CuES-induced cell death in astrocytes indicating that oxidative stress is a mediator of CuES-induced glial toxicity. Lastly, prior induction of metallothioneins 1 and 2 in astrocytes with zinc plus pyrithione was strikingly protective against CuES toxicity. As neurons express high levels of metallothioneins basally, these results may partially account for their resistance to CuES toxicity. These results demonstrate a unique toxic response to copper in glial cells which contrasts with the cell selectivity profile of zinc, another biologically relevant metal.

RESUMEN

BACKGROUND: Many pregnant and parenting people with substance use disorders (SUD) refrain from seeking perinatal care or treatment for their SUD for fear of being treated poorly by health care providers and/or triggering a child welfare investigation. For those who do seek treatment, there are relatively few clinicians willing and able to prescribe medications for opioid use disorder (MOUD) to pregnant people. Both stigma and lack of access to treatment put many pregnant and parenting people at risk. Drug-related deaths contribute significantly to U.S. maternal mortality rates, with people at especially high risk of drug overdose in the months following delivery. METHODS: The Foundation for Opioid Response Efforts (FORE) is a national philanthropy focused on finding and fostering solutions to the opioid crisis. We draw lessons from our grantees' efforts to expand access to substance use treatment and recovery supports for pregnant and parenting people. RESULTS: To build systems of care that ensure more pregnant people get timely perinatal care, we need to expand training for perinatal providers on how to provide OUD treatment, clarify child welfare reporting rules, and engage and support trusted organizations and community-based services. CONCLUSIONS: In addition to changes to our systems of SUD treatment and recovery, we need greater philanthropic investment in efforts to combat the public health crisis of substance use and overdose among pregnant and parenting people. Private funders have the leeway to act quickly, take risks, and demonstrate the effectiveness of new approaches, building the case for investment of public resources in such initiatives.

RESUMEN

SETTING: Early in the pandemic, KFL&A Public Health needed a way to capture, organize, and display COVID-19-related events to be accountable for and evaluate our actions. INTERVENTION: We used accessible software (Microsoft Office 365 suite, Microsoft PowerBI) to develop a data collection and visualization system. The Canadian Institute for Health Information (CIHI) developed a timeline and categorization approach for provincial and national COVID-related interventions, which was used to develop a regional version for local events using similar categories. We collected and displayed qualitative data alongside epidemiological data that allowed users to display different timelines of actions and outcomes and evaluate our response. OUTCOMES: In developing the timeline, we took stock of the information and data we wanted to collect, sort, and display locally. Next, we collected information on response actions, case and contact tracing, and staffing changes in a database that we displayed on a timeline. We included CIHI's data set to provide insight into pandemic response across all jurisdictions. IMPLICATIONS: Our timeline tool has many advantages for public health authorities beyond responding to a rapidly evolving emergency. By collecting information on events as they occur, decisions and actions are documented that may otherwise be overlooked. This enables decision-makers to visualize the impact of public health actions on health outcomes over time. The tool is completely customizable and scalable depending on the project scope and we plan to apply this method to other public health programming. Finally, we include lessons learned from quickly developing these tools in a real-time pandemic setting, both locally at KFL&A Public Health and nationally at CIHI.


RéSUMé: LIEU: Au début de la pandémie, le Bureau de santé de Kingston, Frontenac, Lennox et Addington (KFL&A) avait besoin d'un moyen de saisir, d'organiser et de présenter les événements liés à la COVID-19 pour pouvoir en rendre compte et évaluer ses actions. INTERVENTION: Nous avons utilisé des logiciels accessibles (Microsoft Office 365, Microsoft PowerBI) pour mettre au point un système de collecte et de visualisation de données. L'Institut canadien d'information sur la santé (ICIS) a créé un fil d'actualité et une approche de catégorisation pour les interventions provinciales et nationales liées à la COVID; nous avons créé une version régionale de ces outils pour présenter les événements locaux, en utilisant des catégories semblables. Nous avons collecté et affiché des données qualitatives en plus des données épidémiologiques, ce qui a permis aux utilisateurs d'afficher les mesures prises et leurs résultats sur différentes périodes et d'évaluer leurs interventions. RéSULTATS: Pour créer ce fil d'actualité, nous avons fait l'inventaire des informations et des données que nous voulions collecter, trier et présenter localement. Ensuite, nous avons réuni des informations sur les mesures d'intervention, les enquêtes sur les cas, la recherche de contacts et les changements de personnel dans une base de données, et nous les avons présentées dans un fil d'actualité. Nous avons inclus le jeu de données de l'ICIS pour apporter un éclairage sur la lutte contre la pandémie dans toutes les administrations du pays. CONSéQUENCES: Notre fil d'actualité présente de nombreux avantages pour les autorités de santé publique, en plus de la possibilité de réagir à une situation urgence qui évolue rapidement. En collectant des informations sur les événements à mesure qu'ils se produisent, il est possible de documenter des décisions et des mesures qui risquent d'être oubliées sinon. Cela permet aux décideurs de visualiser dans le temps l'effet des mesures de santé publique sur les résultats cliniques. L'outil est entièrement personnalisable et évolutif, selon la portée du projet, et nous avons l'intention de l'appliquer à d'autres programmes de santé publique. Enfin, nous présentons les leçons de la mise au point rapide d'un tel outil pendant une pandémie en temps réel, tant à l'échelle locale (à la Santé publique de KFL&A) qu'à l'échelle nationale (à l'ICIS).
