Take-home kits to detect respiratory viruses among healthcare personnel: Lessons learned from a cluster randomized clinical trial.
Ontology highlight
ABSTRACT: Background
Health care personnel (HCP) working in outpatient settings routinely interact with patients with acute respiratory illnesses. Absenteeism following symptom development and lack of staff trained to obtain samples limit efforts to identify pathogens among infected HCP.Methods
The Respiratory Protection Effectiveness Clinical Trial assessed respiratory infection incidence among HCP between 2011 and 2015. Research assistants obtained anterior nasal and oropharyngeal swabs from HCP in the workplace following development of respiratory illness symptoms and randomly while asymptomatic. Participants received take-home kits to self-collect swabs when absent from work. Samples mailed to a central laboratory were tested for respiratory viruses by reverse transcription polymerase chain reaction.Results
Among 2,862 participants, 3,467 swabs were obtained from symptomatic participants. Among symptomatic HCP, respiratory virus was detected in 904 of 3,467 (26.1%) samples. Self-collected samples by symptomatic HCP at home had higher rates of viral detection (40.3%) compared to 24% obtained by trained research assistants in the workplace (P < .001).Conclusions
In this randomized clinical trial, take-home kits were an easily implemented, effective method to self-collect samples by HCP. Other studies have previously shown relative equivalence of self-collected samples to those obtained by trained healthcare workers. Take-home kit self-collection could diminish workforce exposures and decrease the demand for personnel protective equipment worn to protect workers who collect respiratory samples.

Project description:ObjectivesThis study describes the 2016 expansion of the British Columbia Take Home Naloxone (BCTHN) programme quantitatively and explores the challenges, facilitators and successes during the ramp up from the perspectives of programme stakeholders.DesignMixed-methods study.SettingThe BCTHN programme was implemented in 2012 to reduce opioid overdose deaths by providing naloxone kits and overdose recognition and response training in BC, Canada. An increase in the number of overdose deaths in 2016 in BC led to the declaration of a public health emergency and a rapid ramp up of naloxone kit production and distribution. BCTHN distributes naloxone to the five regional health authorities of BC.ParticipantsFocus groups and key informant interviews were conducted with 18 stakeholders, including BC Centre for Disease Control staff, urban and rural site coordinators, and harm reduction coordinators from the five regional health authorities across BC.Primary and secondary outcome measuresTake Home Naloxone (THN) programme activity, qualitative themes and lessons learnt were identified.ResultsIn 2016, BCTHN responded to a 20-fold increase in demand of naloxone kits and added over 300 distribution sites. Weekly numbers of overdose events and overdose deaths were correlated with increases in THN kits ordered the following week, during 2013-2017. Challenges elicited include forecasting demand, operational logistics, financial, manpower and policy constraints. Facilitators included outsourcing kit production, implementing standing orders and policy changes in naloxone scheduling, which allowed for easier hiring of staff, reduced paperwork and expanded client access.ConclusionFor THN programmes preparing for potential increases in naloxone demand, we recommend creating an online database, implementing standing orders and developing online training resources for standardised knowledge translation to site staff and clients.

Project description:Noroviruses (NoVs) are highly prevalent, positive-sense RNA viruses that infect a range of mammals, including humans and mice. Murine noroviruses (MuNoVs) are the most prevalent pathogens in biomedical research colonies, and they have been used extensively as a model system for human noroviruses (HuNoVs). Despite recent successes in culturing HuNoVs in the laboratory and a small animal host, studies of human viruses have inherent limitations. Thus, owing to its versatility, the MuNoV system-with its native host, reverse genetics, and cell culture systems-will continue to provide important insights into NoV and enteric virus biology. In the current review, we summarize recent findings from MuNoVs that increase our understanding of enteric virus pathogenesis and highlight similarities between human and murine NoVs that underscore the value of MuNoVs to inform studies of HuNoV biology. We also discuss the potential of endemic MuNoV infections to impact other disease models.

Project description:Background and objectiveIntermountain Healthcare has a long history of using coded terminology and detailed clinical models (DCMs) to govern storage of clinical data to facilitate decision support and semantic interoperability. The latest iteration of DCMs at Intermountain is called the clinical element model (CEM). We describe the lessons learned from our CEM efforts with regard to subjective decisions a modeler frequently needs to make in creating a CEM. We present insights and guidelines, but also describe situations in which use cases conflict with the guidelines. We propose strategies that can help reconcile the conflicts. The hope is that these lessons will be helpful to others who are developing and maintaining DCMs in order to promote sharing and interoperability.MethodsWe have used the Clinical Element Modeling Language (CEML) to author approximately 5000 CEMs.ResultsBased on our experience, we have formulated guidelines to lead our modelers through the subjective decisions they need to make when authoring models. Reported here are guidelines regarding precoordination/postcoordination, dividing content between the model and the terminology, modeling logical attributes, and creating iso-semantic models. We place our lessons in context, exploring the potential benefits of an implementation layer, an iso-semantic modeling framework, and ontologic technologies.ConclusionsWe assert that detailed clinical models can advance interoperability and sharing, and that our guidelines, an implementation layer, and an iso-semantic framework will support our progress toward that goal.

Project description:'Take Home' Naloxone (THN) kits for use by peers in the event of an opioid overdose may reduce further overdose and deaths, but distribution through Drugs Services may not reach those at highest risk. Attendance by paramedics at emergency calls for patients who have suffered an overdose presents an opportunity to distribute THN kits. In this feasibility study we will assess the acceptability of this intervention, and gather data to inform definitive trial planning.Cluster randomised trial with staggered allocation of paramedics (clusters) to groups. We will invite paramedics in an urban area of south Wales, UK to take part. We will randomly allocate those that accept to training sessions during the first 4 months of the trial. Patients attended by paramedics who have been trained and issued THN kits will fall into the intervention group. Patients attended by paramedics following usual practice (until they receive their training and THN kits) will fall into the control group. We will gather data about processes and outcomes of care: numbers of patients eligible for intervention, offered and accepted THN, attended emergency department, suffered further overdose, died within 3 months and about follow-up rates: numbers of patients consented, completed (postal or telephone) questionnaire. We will gather qualitative data about acceptability to patients and paramedics through interviews and focus groups.Ethical approval for this study was granted on 7 December 2011, by South East Wales Research Ethics Committee, Panel C. Results of this study will be reported through peer-reviewed scientific journals, conference presentations and internal organisational report. We will also seek to report our findings through local and national substance misuse networks and publications.ISRCTN98216498.

Project description:This study investigated the experiences of gay, bisexual, and other men who have sex with men (GBM) conducting HIV and sexually transmitted infection (STI) self-testing procedures. We analyzed mixed-methods data from 11 GBM who self-tested HIV-positive and 1,070 HIV-negative GBM who completed the HIV self-testing and STI self-sampling procedures. Nearly all (99%) reported ease in urine-based STI self-sampling and most (90%) found rectal swab self-collection easy. Most (94%) checked their rapid-HIV self-testing results during the correct window (20-40 minutes), and nearly all (99%) trusted their HIV results. Recommendations for future self-testing procedures are provided based on findings from free-response data.

Project description:Simulation-based research has grown substantially over the past two decades; however, relatively few published simulation studies are multicenter in nature. Multicenter research confers many distinct advantages over single-center studies, including larger sample sizes for more generalizable findings, sharing resources amongst collaborative sites, and promoting networking. Well-executed multicenter studies are more likely to improve provider performance and/or have a positive impact on patient outcomes. In this manuscript, we offer a step-by-step guide to conducting multicenter, simulation-based research based upon our collective experience with the International Network for Simulation-based Pediatric Innovation, Research and Education (INSPIRE). Like multicenter clinical research, simulation-based multicenter research can be divided into four distinct phases. Each phase has specific differences when applied to simulation research: (1) Planning phase, to define the research question, systematically review the literature, identify outcome measures, and conduct pilot studies to ensure feasibility and estimate power; (2) Project Development phase, when the primary investigator identifies collaborators, develops the protocol and research operations manual, prepares grant applications, obtains ethical approval and executes subsite contracts, registers the study in a clinical trial registry, forms a manuscript oversight committee, and conducts feasibility testing and data validation at each site; (3) Study Execution phase, involving recruitment and enrollment of subjects, clear communication and decision-making, quality assurance measures and data abstraction, validation, and analysis; and (4) Dissemination phase, where the research team shares results via conference presentations, publications, traditional media, social media, and implements strategies for translating results to practice. With this manuscript, we provide a guide to conducting quantitative multicenter research with a focus on simulation-specific issues.

Project description:BackgroundIn this study, we sought to assess healthcare professionals' acceptance of and satisfaction with a shared decision making (SDM) educational workshop, its impact on their intention to use SDM, and their perceived facilitators and barriers to the implementation of SDM in clinical settings in Iran.MethodsWe conducted an observational quantitative study that involved measurements before, during, and immediately after the educational intervention at stake. We invited healthcare professionals affiliated with Tabriz University of Medical Sciences, East Azerbaijan, Iran, to attend a half-day workshop on SDM in December 2016. Decisions about prenatal screening and knee replacement surgery was used as clinical vignettes. We provided a patient decision aid on prenatal screening that complied with the International Patient Decision Aids Standards and used illustrate videos. Participants completed a sociodemographic questionnaire and a questionnaire to assess their familiarity with SDM, a questionnaire based on theoretical domains framework to assess their intention to implement SDM, a questionnaire about their perceived facilitators and barriers of implementing SDM in their clinical practice, continuous professional development reaction questionnaire, and workshop evaluation. Quantitative data was analyzed descriptively and with multiple linear regression.ResultsAmong the 60 healthcare professionals invited, 41 participated (68%). Twenty-three were female (57%), 18 were specialized in family and emergency medicine, or community and preventive medicine (43%), nine were surgeons (22%), and 14 (35%) were other types of specialists. Participants' mean age was 37.51 ± 8.64 years with 8.09 ± 7.8 years of clinical experience. Prior to the workshop, their familiarity with SDM was 3.10 ± 2.82 out of 9. After the workshop, their belief that practicing SDM would be beneficial and useful (beliefs about consequences) (beta = 0.67, 95% CI 0.27, 1.06) and beliefs about capability of using SDM (beta = 0.32, 95% CI -0.08, 0.72) had the strongest influence on their intention of practicing SDM. Participants perceived the main facilitator and barrier to perform SDM were training and high patient load, respectively.ConclusionsParticipants thought the workshop was a good way to learn SDM and that they would be able to use what they had learned in their clinical practice. Future studies need to study the level of intention of participants in longer term and evaluate the impact of cultural differences on practicing SDM and its implementation in both western and non-western countries.

Project description:A World Health Organization (WHO)/United Nations Children's Fund (UNICEF) (2009) joint statement recommended home visits by community-based agents as a strategy to improve newborn survival, based on promising results from Asia. This article presents detailed evaluation of community volunteer assessment and referral implemented within the Ghana Newhints home visits cluster-Randomized Controlled Trial (RCT). It highlights the lessons learned to inform implementation/scale-up of this model in similar settings. The evaluation used a conceptual framework adopted for increasing access to care for sick newborns and involves three main steps, each with a specific goal and key requirements to achieving this. These steps are: sick newborns are identified within communities and referred; families comply with referrals and referred babies receive appropriate management at health facilities. Evaluation data included interviews with 4006 recently delivered mothers; records on 759 directly observed volunteer assessments and 52 validation of supervisors' assessments; newborn care quality assessment in 86 health facilities and in-depth interviews (IDIs) with 55 mothers, 21 volunteers and 15 health professionals. Assessment accuracy of volunteers against supervisors and physician was assessed using Kappa (agreement coefficient). IDIs were analysed by generating and indexing into themes, and exploring relationships between themes and their contextual interpretations. This evaluation demonstrated that identifying, understanding and implementing the key requirements for success in each step of volunteer assessment and referrals was pivotal to success. In Newhints, volunteers (CBSVs) were trusted by families, their visits were acceptable and they engaged mothers/families in decisions, resulting in unprecedented 86% referral compliance and increased (55-77%) care seeking for sick newborns. Poor facility care quality, characterized by poor health worker attitudes, limited the mortality reduction. The important implication for future implementation of home visits in similar settings is that, with 100% specificity but 80% sensitivity of referral decisions, volunteers might miss some danger signs but if successful implementation must translate into mortality reductions, concurrent improvement in facility newborn care quality is imperative.

Project description:BackgroundResearch indicates that the implicit biases and racist attitudes of healthcare workers are fundamental contributing factors to race-based health inequities. However, few studies and reviews appear to have examined the provision and effects of anti-racist education and training on post-licensure healthcare workers. The purpose of this systematic literature review was to explore what research methods are being used to ascertain the training healthcare workers are receiving post-licensure and to identify the goals and outcomes of this training.MethodsUsing PubMed, CINAHL, and Google Scholar databases, peer-reviewed articles meeting inclusion criteria were identified and reviewed by the authors from March through October of 2020 in alignment with the renewed national focus on anti-racism and racial justice. Studies or initiatives involving students were excluded as were commentaries on studies and studies not specific to racism or anti-racism.ResultsEleven articles were identified as meeting stipulated inclusion criteria. Few were outcome studies (n = 3), and many articles did not clearly delineate training methods, content, or outcomes assessed. Identified methods included group discussion, case studies, and online modules. Reported outcomes included increased self-awareness of implicit biases and racism. Only two studies focused specifically on nurses, with the majority of studies centering on physicians (n = 5).ConclusionsA considerable knowledge gap exists regarding effective methods, tools, and outcomes to use for undoing racism and mitigating bias in healthcare professionals. Nothing less than a seismic paradigm shift is called for, one in which an anti-racist perspective informs all healthcare education, research, and practice.

Project description:BackgroundThe current outbreak of the coronavirus disease (COVID-19) is of unprecedented proportions in several regards. Recent reports suggest that many frontline healthcare workers (HCWs) suffer from mental health problems, including posttraumatic stress symptoms (PTSS). Previous studies have identified several key factors associated with short-term PTSS in pandemic HCWs, yet limited data is available on factors associated with long-term PTSS. Understanding the psychological impact of the pandemic on HCWs is important in planning for future outbreaks of emerging infectious diseases. In the current study, we look to findings from a highly relevant subsection of the trauma field, the military domain.ObjectivePandemic HCWs and military peacekeepers may experience similar stressors in the line of duty. This study investigated whether factors linked to short-term PTSS in pandemic HCWs were also associated with long-term PTSS in military peacekeepers.Materials and methodsPeacekeepers who reported pandemic-relevant stressors during deployment to a UN peacekeeping mission were included in the study (N = 1,627). PTSS was self-reported using the Posttraumatic Stress Disorder Checklist - Military Version. Descriptive instruments were used to assess possible factors associated with PTSS. A multiple linear regression analysis was performed to explore associations between these factors and PTSS.ResultsOur model accounted for 50% of the variance in PTSS, F(1503,11) = 139.00, p < 0.001. Age, relationship and employment status, preparedness, working environment, social support after deployment, barriers to disclose, recognition, and loneliness were all significantly associated with PTSS on average 30 years after deployment. The most important risk factors of long-term PTSS were personal barriers to disclose one's experiences and current unemployment.ConclusionSeveral factors linked to short-term PTSS in pandemic HCWs were associated with long-term PTSS in peacekeepers. We discuss how these findings may be used to prevent long-term PTSS in HCWs involved in the current COVID-19 outbreak.
