RESUMEN

OBJECTIVE: Pasteurization kills harmful microorganisms found in milk. While consumption of unpasteurized milk and its products is discouraged due to increased risk of infections, some individuals prefer unpasteurized dairy products. Our objective was to estimate the burden of illness from outbreaks arising from consumption of unpasteurized and pasteurized dairy products in Canada and the United States. METHODS: We conducted a systematic review of dairy-associated outbreaks in Canada and the USA from 2007 onward. We searched MEDLINE, Embase, Cochrane Library, TRIP Database for guidelines, and North American government agency websites up to October 2020. We included outbreak reports where the pathogenic microbe was confirmed in both the patient and the dairy product through laboratory testing. SYNTHESIS: Thirty-two disease outbreaks were linked to dairy consumption. Twenty outbreaks involving unpasteurized products resulted in 449 confirmed cases of illness, 124 hospitalizations, and five deaths. Twelve outbreaks involving pasteurized products resulted in 174 confirmed cases of illness, 134 hospitalizations, 17 deaths, and seven fetal losses. Listeria accounted for 10 out of 12 outbreaks from pasteurized products from 2007 through 2020. CONCLUSION: Public warnings about the risk of unpasteurized dairy consumption need to continue and pregnant women and immunocompromised hosts need to be made aware of foods at high risk of contamination with Listeria.

RéSUMé: OBJECTIF: La pasteurisation tue les micro-organismes dangereux contenus dans le lait. Même si la consommation du lait non pasteurisé et ses produits fût déconseillée en raison d'un risque accru d'infection, certaines personnes préfèrent des produits laitiers non pasteurisés. Notre objectif était d'évaluer le fardeau de maladie des éclosions résultant de la consommation des produits laitiers non pasteurisés et pasteurisés au Canada et aux États-Unis. MéTHODE: Nous avons mené une revue systématique des éclosions liées aux produits laitiers au Canada et aux États-Unis depuis 2007. Nous avons cherché dans MEDLINE, Embase, Cochrane Library, TRIP Database et les sites web des agences gouvernementales Nord-Américaines pour la période 2007 jusqu'au mois d'octobre 2020. Nous avons inclus des rapports d'éclosion lorsque les essais en laboratoire ont confirmé la présence du microbe pathogène dans le patient ainsi que dans le produit laitier. RéSULTATS: Trente-deux éclosions étaient liées à la consommation des produits laitiers. Les produits non pasteurisés étaient impliqués dans 20 éclosions, avec 449 cas de maladie confirmés, 124 hospitalisations et 5 morts. Les produits pasteurisés étaient impliqués dans 12 éclosions, avec 174 cas de maladie confirmés, 134 hospitalisations, 17 morts et sept morts fœtales. Listeria comptait pour 10 des 12 éclosions des produits pasteurisés de 2007 à 2020. CONCLUSION: Les avis publics au sujet du risque de la consommation des produits laitiers non pasteurisés devraient continuer et les femmes enceintes et les hôtes immunodéprimés devraient être informés de la nourriture à haut risque de la contamination avec Listeria.

RESUMEN

The Cochrane COVID-19 Study Register (CCSR) is a public, continually updated database of COVID-19 study references. The aim of this study-based register is to support rapid and living evidence synthesis, including an evidence ecosystem of COVID-19 research (CEOsys). In November and December 2020, we conducted an evaluation of the CCSR for CEOsys, measured its performance and identified areas for improvement. For the evaluation we generated a purposive sample of 286 studies from 20 reviews to calculate the CCSR's comprehensiveness (sensitivity), accuracy (correctly classified and linked studies) and currency (time to publish and process references). Our sample showed that the CCSR had an overall comprehensiveness of 77.2%, with the highest coverage for interventional studies (94.4%). The study register had 100% coverage for trial registry records, 86.5% for journal articles and 52.4% for preprints. A total of 98.3% of references were correctly classified with regard to study type, and 93.4% with regard to study aim. A total of 89% of studies were correctly linked. A total of 81.4% of references were published to the register in under 30 days, with 0.5 day (median) for trial registry records, 2 days for journal articles and 56 days for preprints. The CCSR had high comprehensiveness, accurate study classifications and short publishing times for journal articles and trial registry records in the sample. We identified that coverage and publishing time for preprints needed improvement. Finally, the evaluation illustrated the value of a study-based register for identifying additional study references for analysis in evidence synthesis.

RESUMEN

OBJECTIVES: Patient priority setting projects (PPSPs) can reduce research agenda bias. A key element of PPSPs is a review of available literature to determine if the proposed research priorities have been addressed, identify research gaps, recognise opportunities for knowledge translation (KT) and avoid duplication of research efforts. We conducted rapid responses for 11 patient-identified priorities in depression to provide a map of the existing evidence. DESIGN: Eleven rapid responses. DATA SOURCES: Single electronic database (PubMed). ELIGIBILITY CRITERIA: Each rapid response had unique eligibility criteria. For study designs, we used a stepwise inclusion process that started with systematic reviews (SRs) if available, then randomised controlled trials and observational studies as necessary. RESULTS: For all but one of the rapid responses we identified existing SRs (median 7 SRs per rapid response, range 0-179). There were questions where extensive evidence exists (ie, hundreds of primary studies), yet uncertainties remain. For example, there is evidence supporting the effectiveness of many non-pharmacological interventions (including psychological interventions and exercise) to reduce depressive symptoms. However, targeted research is needed that addresses comparative effectiveness of promising interventions, specific populations of interest (eg, children, minority groups) and adverse effects. CONCLUSIONS: We identified an extensive body of evidence addressing patient priorities in depression and mapped the results and limitations of existing evidence, areas of uncertainty and general directions for future research. This work can serve as a solid foundation to guide future research in depression and KT activities. Integrated knowledge syntheses bring value to the PPSP process; however, the role of knowledge synthesis in PPSPs and methodological approaches are not well defined at present.

RESUMEN

CONTEXT: Children in care of the child welfare system tend to underutilize preventive health services compared with other children. The purpose of this systematic review was to assess current knowledge regarding immunization coverage levels for children in the child welfare system and to determine barriers and supports to them utilizing immunization services. EVIDENCE ACQUISITION: Articles published in Medline, Embase, Cochrane Library, CINAHL, SocINDEX, and ERIC from January 1, 2000 to October 13, 2017 were searched. Thesis and conference databases and relevant websites were also examined. Studies were included if written in English, from high-income countries, and addressed immunizations for children in the child welfare system. Independent dual screening, extraction, and quality appraisal were conducted between October 2016 and December 2017, followed by narrative synthesis. EVIDENCE SYNTHESIS: Of 2,906 records identified, 33 met inclusion criteria: 21 studied coverage, two studied barriers/supports, and ten studied both. Nineteen studies were moderate or high quality and thus included in the narrative synthesis; 15 studied coverage, one studied barriers/supports, and three studied both. Most studies found lower coverage among children in child welfare. The few studies that explicitly studied barriers/supports to immunization identified that a collaborative and coordinated approach between health and social services was key to service delivery to this population. CONCLUSIONS: This review highlights that children in care of the child welfare system are at risk of poor immunization coverage. There is a need for high-quality studies on this issue, with a focus on assessing supports/barriers to immunization in this population.

RESUMEN

TREKK (Translating Emergency Knowledge for Kids) was established to address knowledge needs to support care of children in general emergency departments. To achieve this goal, we developed an integrated knowledge translation (KT) process based on identified priorities to create the TREKK Evidence Repository, containing "knowledge pyramids" and Bottom Line Recommendations (summary documents) on the diagnosis and treatment of emergency pediatric conditions. The objective of this article is to describe our methods for developing and disseminating the TREKK Evidence Repository to improve pediatric emergency care in Canada. Our work was guided by the research question: Can an integrated KT process address an information gap in healthcare practice? We utilized a pyramid-shaped framework, built upon the "4S" hierarchy of evidence model, to provide detailed evidence appropriate to stakeholders' needs. For each priority condition (asthma, bronchiolitis, croup, etc.), clinical advisors and KT experts collaborated to create a Bottom Line Recommendation and to select guidelines, reviews, and key studies for that condition's topic area in the Evidence Repository on the TREKK website (trekk.ca). Targeted promotion, including a social media campaign, communicated the availability of new topics in the Evidence Repository and available knowledge tools. Feedback from 35 end-users on pilot versions of the Evidence Repository was positive with 91% indicating that they would use the resource in the emergency department. Using an integrated KT process, we responded to end-users' requests for varying level of information on priority pediatric conditions through the creation of knowledge tools and development of a process to identify and vet high quality evidence-based resources.

RESUMEN

BACKGROUND: Health care providers value ready access to reliable synthesized information to support point-of-care decision making. Web-based communities, facilitated by the adoption of social media tools such as Facebook, Twitter, and YouTube, are increasingly being used for knowledge dissemination, bridging the gap between knowledge generation and synthesis and knowledge implementation. OBJECTIVE: Our objective was to implement and evaluate a structured social media strategy, using multiple platforms, to disseminate Cochrane Child Health evidence to health care providers caring for children. METHODS: Our social media strategy had three components: daily "tweets" using the Cochrane Child Health Twitter account, weekly WordPress blog posts, and a monthly journal club on Twitter ("tweet chat"). Each tweet, blog, and journal club shared Cochrane evidence on a child health topic. We evaluated the strategy through (1) Twitter and blog site analytics, (2) traceable link (Bitly) statistics, (3) Altmetric.com scores for promoted evidence, and (4) participant feedback. We also tracked the resources required to write the blog, tweet content, and manage the strategy. RESULTS: The 22-week social media strategy ran between November 2014 and April 2015. We created 25 blog posts, sent 585 tweets, and hosted 3 tweet chats. Monthly blog visits and views and Twitter account followers increased over time. During the study period, the blog received 2555 visitors and 3967 page views from a geographically diverse audience of health care providers, academics, and health care organizations. In total, 183 traceable Bitly links received 3463 clicks, and the Twitter account gained 469 new followers. The most visited and viewed blog posts included gastrointestinal topics (lactose avoidance), research on respiratory conditions (honey for cough and treatments for asthma), and maternal newborn care (skin-to-skin contact). On Twitter, popular topics were related to public health (vaccination) and pain management. We collected Altmetric.com scores for 61 studies promoted during the study period and recorded an average increase of 11 points. Research staff (n=3) contributed approximately 433 hours to promotion activities and planning (6.5 hours each per week) to implement the social media strategy, and study investigators reviewed all content (blog posts and tweets). CONCLUSIONS: This study provides empirical evidence on the use of a coordinated social media strategy for the dissemination of evidence to professionals providing health services to children and youth. The results and lessons learned from our study provide guidance for future knowledge dissemination activities using social media tools.

RESUMEN

INTRODUCTION: Children may be placed in the care of the child welfare system when they require additional supports or intervention to ensure their safety and security. Transitions in living arrangements (eg, home to foster care and return to home) and other difficult circumstances for these children may result in interruptions in routine preventive healthcare, such as childhood immunisations. The purpose of this systematic literature review is to determine whether immunisation coverage is a problem among children in the child welfare system and identify any known supports and/or barriers to vaccine uptake in this population. METHODS AND ANALYSIS: This systematic review will encompass published and unpublished primary research studies that assess (A) immunisation coverage of children in the child welfare system, (B) how this coverage compares to the general population and/or children not in the child welfare system, and (C) supports and barriers affecting immunisation status of these children. Vaccines in the recommended childhood immunisation schedule for each study setting will be considered. Medline, Embase, Cochrane Library, CINAHL, SocINDEX and ERIC will be comprehensively searched. We will also search ProQuest dissertations and theses, the Conference Proceedings Citation Index for Science and Social Science & Humanities, and a sample of relevant provincial, national and international websites. References of included studies will be manually searched for relevant studies. English language primary studies from 2000 to current focused on immunisations of children (age 0-17 years) in the child welfare system, in a high-income country, will be included. A narrative analysis of key findings from included studies will be performed and presented. ETHICS AND DISSEMINATION: This protocol does not require ethics approval. Planned dissemination includes peer-reviewed publication, conference presentations and briefs for policy makers. TRIAL REGISTRATION NUMBER: This protocol is registered in the PROSPERO International Prospective Register of Systematic Reviews, registration number CRD42016047319.

RESUMEN

Background: Electronic alerts (e-alerts) for acute kidney injury (AKI) in hospitalized patients are increasingly being implemented; however, their impact on outcomes remains uncertain. Methods: We performed a systematic review. Electronic databases and grey literature were searched for original studies published between 1990 and 2016. Randomized, quasi-randomized, observational and before-and-after studies that included hospitalized patients, implemented e-alerts for AKI and described their impact on one of care processes, patient-centred outcomes or resource utilization measures were included. Results: Our search yielded six studies ( n = 10 165 patients). E-alerts were generally automated, triggered through electronic health records and not linked to clinical decision support. In pooled analysis, e-alerts did not improve mortality [odds ratio (OR) 1.05; 95% confidence intervals (CI), 0.84-1.31; n = 3 studies; n = 3425 patients; I 2 = 0%] or reduce renal replacement therapy (RRT) use (OR 1.20; 95% CI, 0.91-1.57; n = 2 studies; n = 3236 patients; I 2 = 0%). Isolated studies reported improvements in selected care processes. Pooled analysis found no significant differences in prescribed fluid therapy. Conclusions: In the available studies, e-alerts for AKI do not improve survival or reduce RRT utilization. The impact of e-alerts on processes of care was variable. Additional research is needed to understand those aspects of e-alerts that are most likely to improve care processes and outcomes.

RESUMEN

CONTEXT: In spontaneously breathing preterm infants with respiratory distress syndrome (RDS) receiving nasal continuous positive airway pressure, a method of less invasive surfactant administration (LISA) using a thin catheter has been described as an alternative to endotracheal intubation for surfactant delivery to reduce lung injury. OBJECTIVE: A systematic review of randomised controlled trials (RCTs) comparing LISA with the standard method of surfactant delivery for clinical outcomes. METHODS: Medline, CENTRAL and Embase databases were searched (until 29 October 2015). Additional citations were identified from trial registries, conference proceedings and the bibliographies of selected articles. The included studies were RCTs enrolling preterm infants with RDS and compared LISA technique with intubation for surfactant delivery for any of the prespecified clinical outcomes. RESULTS: Six RCTs were identified, enrolling a total of 895 infants. The use of LISA technique reduced the composite outcome of death or bronchopulmonary dysplasia (BPD) at 36 weeks (risk ratio (RR)=0.75 (95% CI 0.59 to 0.94), p=0.01), BPD36 among survivors (RR=0.72 (0.53 to 0.97), p=0.03), need for mechanical ventilation within 72 hours of birth (RR=0.71 (0.53 to 0.96), p=0.02) or need for mechanical ventilation anytime during the neonatal intensive care unit stay (RR=0.66 (0.47 to 0.93), p=0.02). There were no differences noted for the outcome of death and other neonatal morbidities. Procedure failure rate on the first attempt and the need for additional doses of surfactant were not different between the intervention groups. CONCLUSIONS: LISA technique for surfactant delivery results in a lesser need for mechanical ventilation in infants with RDS, reduction in the composite outcome of death or BPD at 36 weeks, and BPD36 among survivors.

RESUMEN

BACKGROUND: Rapid review (RR) products are inherently appealing as they are intended to be less time-consuming and resource-intensive than traditional systematic reviews (SRs); however, there is concern about the rigor of methods and reliability of results. In 2013 to 2014, a workgroup comprising representatives from the Agency for Healthcare Research and Quality's Evidence-based Practice Center Program conducted a formal evaluation of RRs. This paper summarizes results, conclusions, and recommendations from published review articles examining RRs. METHODS: A systematic literature search was conducted and publications were screened independently by two reviewers. Twelve review articles about RRs were identified. One investigator extracted data about RR methods and how they compared with standard SRs. A narrative summary is presented. RESULTS: A cross-comparison of review articles revealed the following: 1) ambiguous definitions of RRs, 2) varying timeframes to complete RRs ranging from 1 to 12 months, 3) limited scope of RR questions, and 4) significant heterogeneity between RR methods. CONCLUSIONS: RR definitions, methods, and applications vary substantially. Published review articles suggest that RRs should not be viewed as a substitute for a standard SR, although they have unique value for decision-makers. Recommendations for RR producers include transparency of methods used and the development of reporting standards.

RESUMEN

OBJECTIVE: The research provides an understanding of pandemic information needs and informs professional development initiatives for librarians in disaster medicine. METHODS: Utilizing a multisite, comparative case series design, the researchers conducted semi-structured interviews and examined supplementary materials in the form of organizational documents, correspondence, and websites to create a complete picture of each case. The rigor of the case series was ensured through data and investigator triangulation. Interview transcripts were coded using NVivo to identify common themes and points of comparison. RESULTS: Comparison of the four cases revealed a distinct difference between "client-initiated" and "librarian-initiated" provision of pandemic information. Librarian-initiated projects utilized social software to "push" information, whereas client-initiated projects operated within patron-determined parameters to deliver information. Health care administrators were identified as a key audience for pandemic information, and news agencies were utilized as essential information sources. Librarians' skills at evaluating available information proved crucial for selecting best-quality evidence to support administrative decision making. CONCLUSIONS: Qualitative analysis resulted in increased understanding of pandemic information needs and identified best practices for disseminating information during periods of high organizational stress caused by an influx of new cases of an unknown infectious disease.

RESUMEN

OBJECTIVES: To develop a knowledgebase of stories illustrating the variety of roles that librarians can assume in emergency and disaster planning, preparedness, response, and recovery, the National Library of Medicine conducted an oral history project during the summer of 2007. The history aimed to describe clearly and compellingly the activities--both expected and unusual--that librarians performed during and in the aftermath of the disasters. While various types of libraries were included in interviews, the overall focus of the project was on elucidating roles for medical libraries. METHODS: Using four broad questions as the basis for telephone and email interviews, the investigators recorded the stories of twenty-three North American librarians who responded to bombings and other acts of terrorism, earthquakes, epidemics, fires, floods, hurricanes, and tornados. RESULTS: Through the process of conducting the oral history, an understanding of multiple roles for libraries in disaster response emerged. The roles fit into eight categories: institutional supporters, collection managers, information disseminators, internal planners, community supporters, government partners, educators and trainers, and information community builders. CONCLUSIONS: Librarians--particularly health sciences librarians--made significant contributions to preparedness and recovery activities surrounding recent disasters. Lessons learned from the oral history project increased understanding of and underscored the value of collaborative relationships between libraries and local, state, and federal disaster management agencies and organizations.
