Medical-surgical nurses at the project site demonstrated a knowledge deficit regarding the care of adult patients with a tracheostomy. Such knowledge deficits could expose patients to higher risks for infection, bedsores, prolonged hospital stays, increased costs, increased caregiver burden, and death. The purpose of this project was to develop an educational program to improve nurses'€™ knowledge and confidence in the provision of evidence-based tracheostomy care to answer the question if the content of an evidence-based educational program developed to improve nurses'€™ knowledge and confidence in managing adult patients with tracheostomy on a medical-surgical floor would meet the expectations of a panel of content experts. Bandura'€™s self-efficacy and social learning theories provided theoretical guidance for the project. Five local nurse practitioners served as content experts and made recommendations about how the program could be improved, as well as suggestions relating to the wording of and the time allowed for the simulation aspect of the program. Content experts used a 5-point Likert-scale survey to evaluate the education at the completion of the program. Results showed that all reviewers strongly agreed that the content of the program was relevant, was based on the best available evidence, and was well organized and easy to follow. This project may promote positive change on the medical-surgical floor by improving providers'€™ knowledge, skills, and confidence in the provision of care based on the best available evidence, which may lead to improvements in the quality of care provided to tracheostomized patients.

Since 1999, Methicillin-resistant Staphylococcus aureus (MRSA) outbreaks have occurred in many correctional facilities. Even after the Federal Bureau of Prisons developed clinical practice guidelines on the management of MRSA within correctional facilities, the prevalence of MRSA decreased only insignificantly. Other researchers suggested infection control compliance was equally as important as developing clinical practice guidelines in reducing the incidence of MRSA. Several studies identified the healthcare professionals' nonadherence and inconsistencies to clinical practice guidelines as contributors to MRSA transmission. Accordingly, this project was designed to develop evidence-based recommendations for improving nurse professionals' adherence to MRSA practice guidelines in correctional settings. Using the health belief model as the theoretical framework, this project examined the nurse professionals' perceptions as well as their level of knowledge regarding MRSA by using an original instrument, Knowledge and Health Beliefs Regarding MRSA Questionnaire. The study employed a quantitative design with a purposeful sample of 36 participants using social media. Through descriptive statistical analysis, it was determined that MRSA training and education were the greatest barriers among the nurse professionals in taking MRSA preventive action (64%, n = 23). Based on the findings, assessing the educational needs of the nurse professionals must become the priority when designing infection control programs. This study contributes to social change by recognizing the potential health impact of MRSA and cautions that if public health officials do not control MRSA within correctional settings, such behavior can affect the transmission of MRSA both nationally and globally.

(English) Smoking is the leading cause of premature mortality and morbidity globally (WHO, 2018). Within the Czech Republic (CR) tobacco consumption ranks among the highest in the world, and tobacco control measures rank among the poorest globally (Joossens and Raw, 2014; American Cancer Society, 2018). Smoking related chronic diseases and the loss of active part of life are an enormous and growing burden on the Czech system. There is urgency to invest in efforts that will control and decrease the demand for tobacco products (OECD, 2017). Experiences and lessons learned in tobacco control (TC) by other countries, such as Canada, may provide valuable insight to help guide Czech decision makers in identifying policy best buys moving forward. The basic research carried out as part of this PhD project focuses specifically on a comparison of TC in Canada and the CR. It also includes: 1) a national cross-sectional survey of all organizations involved in TC to describe capacity and involvement in TC measures outlined by the WHO Framework Convention on Tobacco Control (FCTC) (Fraser et al. 2019); 2) a prospective cohort study which describes the results of intensive smoking cessation treatment offered by Centers for Tobacco Dependent (CTD) (Králiková et al. 2014); 3) a cross sectional survey of patients...

An evidence-based clinical practice guideline was developed to prevent and manage constipation in long-term care (LTC) residents, a vulnerable population not specifically addressed in previous guidelines. A literature review was completed, and evidence was evaluated and included in initial draft recommendations. The guideline was reviewed for content validity using a Delphi committee of clinical experts in gastroenterology, geriatrics, and pharmacy. The updated guideline was presented to an interdisciplinary team that reviewed its clinical applicability. Overall, interdisciplinary team members agreed or strongly agreed the guideline was clinically applicable (n=30). Finally, the guideline was evaluated by a group of doctorally-prepared practicing nurse practitioners using the Appraisal of Guidelines for Research and Evaluation II instrument. Appraiser scores were 85% or higher in every domain, indicating the guideline was perceived as high in quality. Development of this guideline signifies an initial step in the management and prevention of constipation in LTC residents.

This dissertation presents a body of research consisting of 5 scientific papers with an overarching objective to develop and test interventions that can enhance the dissemination, access and use of current best evidence at the point of care. Questions constantly arise from clinicians’ interactions with their patients, but more than 60% remain unanswered. The first 4 papers therefore focused on evidence dissemination to clinicians and trainees looking for answers and trying to stay alert to new evidence. We used as our “laboratory” an online tool developed at McMaster University’s Health Information Research Unit, the MacPLUS Federated Search (MacPLUS FS), which allows busy clinicians to search multiple top high quality resources simultaneously and display a 1-page output with the most clinically useful results at the top. Guided by effective models for the teaching of clinical skills at the point of care, we designed 3 web-based interventions addressing logistical and educational barriers to increase the quantity and quality of searching for current best evidence. These interventions were: (A) a web-based Clinical Questions Recorder and Reminder; (B) an Evidence Retrieval Coach composed of 8 short videos embedded in MacPLUS; (C) and a Gamified Audit & Feedback based on the allocation of “badges” and “reputation scores” for evidence searching. We tested these interventions in 4 factorial randomized-controlled trials among 1,868 heath care professionals and students currently registered in MacPLUS FS, namely: 477 medical faculty members, 431 postgraduate medical trainees, 725 nursing students and 235 medical students. Results showed that these target populations substantially differed both in their baseline frequency of search and access to alerts, as in their responsiveness to the 3 web-based interventions on evidence utilization. Evidence summaries have traditionally been tailored to meet the educational needs of clinicians, but are seldom provided in a format that supports shared decision-making. Our fifth paper explored a potential solution, which constitutes another route for evidence dissemination and use. In a project called SHARE-IT, we developed a new framework and online prototype for the generic production of decision aids, which allow physicians and patients to discuss the evidence together in the clinical encounter. We present the framework, design methods and early testing of this generic approach, which showed promising results for the translation of evidence summaries into useful tools for shared decision-making. / Thesis / Doctor of Philosophy (PhD)

Title: Clinical Decision Making in Paramedicine Author(s) & affiliation(s): Michael Eby – McMaster University, Hamilton, ON, Canada Sandra Monteiro – McMaster University, Hamilton, ON, Canada Geoffrey Norman – McMaster University, Hamilton, ON, Canada Walter Tavares – McMaster University, Hamilton, ON, Canada Background: Paramedics are frequently required to make rapid decisions in an uncontrolled, dynamic environment, often with limited diagnostic information. In Ontario, paramedic practice is based on a set of provincial medical directives that provide diagnostic and treatment criteria. Unsupervised deviation from these directives is classified as a form of error and highly discouraged. To date, there is little known about how years of clinical experience or level of certification affect the way these medical directives are used. The purpose of this study was to examine the relationship between paramedic experience, training and accuracy of treatment decisions when faced with patients who meet and fall outside of the existing medical directives. Methods: Thirty-one participants (16 experienced / 15 novice) were recruited from two paramedic services in Ontario. “Experienced” was defined as in-practice for 5 years or more. Participants were presented with 9 scenarios; in 6 scenarios, the patient presentation fit within the existing directives, while in 3 scenarios, the patient presentation fell outside the medical directives. Multiple-choice responses were used to capture participants’ decisions to treat or not treat the patients. Responses were scored and submitted to a mixed-factorial ANOVA to evaluate differences in accuracy between case types, years of experience and level of training. Results: There was a significant effect of case type (p < 0.004). Accuracy was lower when the patient presentation did not meet the criteria of the medical directive (76.34% (CI = 67.15% to 85.53%) vs. 98.35% (CI = 96.55% to 100%) when they did. There was no effect of years of clinical practice or level of certification. Conclusion: The results suggest both novice and experienced paramedics are able to accurately apply medical directives, however, there is a significant decrease in accuracy when the patient presentation does not fit one. This variation in practice may have a significant impact on patient safety, and further research is required to determine what factors may be causing this decreased accuracy. / Thesis / Master of Science (MSc) / Paramedics work in a fast-paced, dynamic environment. The types of patients, and the situations paramedics encounter are different every day. Paramedic practice is based on a series of provincial medical directives that outline the different proceedures, medications and types of patients that can be treated. While these directives cover many of the cases paramedics encounter, there will always be cases that don’t “fit”. The purose of this study is to see if paramedics approach those types of cases in a different way, and if their years of experience or level of training change how good they are at idenfiying what patients require treatment. As there is very little paramedic specific research on this topic, this study will serve as a starting point for future research and hopefully stimulate discussion about paramedic practice, and how to support paramedics getting better at their jobs.

An important aspect in the process of architectural design is the testing of solution alternatives in order to evaluate them on their appropriateness within the context of the design problem. Computational Fluid Dynamics (CFD) analysis is one of the approaches that have gained popularity in the testing of architectural design solutions especially for purposes of evaluating the performance of natural ventilation strategies in buildings. Natural ventilation strategies can reduce the energy consumption in buildings while ensuring the good health and wellbeing of the occupants. In order for natural ventilation strategies to perform as intended, a number of factors interact and these factors must be carefully analysed. CFD simulations provide an affordable platform for such analyses to be undertaken. Traditionally, these simulations have largely followed the direction of Best Practice Guidelines (BPGs) for quality control. These guidelines are built around certain simplifications due to the high computational cost of CFD modelling. However, while the computational cost has increasingly fallen and is predicted to continue to drop, the BPGs have largely remained without significant updates. The need to develop a CFD simulation framework that leverages the contemporary and anticipates the future computational cost and capacity can, therefore, not be overemphasised. When conducting CFD simulations during the process of architectural design, the variability of the wind flow field including the wind direction and its velocity constitute an important input parameter. Presently, however, in many simulations, the wind direction is largely used in a steady state manner. It is assumed that the direction of flow downwind of a meteorological station remains constant. This assumption may potentially compromise the integrity of CFD modelling as in reality, the wind flow field is bound to be dynamic from place to place. In order to improve the accuracy of the CFD simulations for architectural design, it is therefore necessary to adequately account for this variability. This study was a two-pronged investigation with the ultimate objective of improving the accuracy of the CFD simulations that are used in the architectural design process, particularly for the design and analysis of natural ventilation strategies. Firstly, a framework for integrated meso-scale and building scale CFD simulations was developed. Secondly, the newly developed framework was then implemented by deploying it to study the variability of the wind flow field between a reference meteorological station, the Virginia Tech Airport, and a selected localized building scale site on the Virginia Tech campus. The findings confirmed that the wind flow field varies from place to place and showed that the newly developed framework was able to capture this variation, ultimately, generating a wind flow field characterization representative of the conditions prevalent at the localized building site. This framework can be particularly useful when undertaking de-coupled CFD simulations to design and analyse natural ventilation strategies in the building design process. / Doctor of Philosophy / The use of natural ventilation strategies in building design has been identified as one viable pathway toward minimizing energy consumption in buildings. Natural ventilation can also reduce the prevalence of the Sick Building Syndrome (SBS) and enhance the productivity of building occupants. This research study sought to develop a framework that can improve the usage of Computational Fluid Dynamics (CFD) analyses in the architectural design process for purposes of enhancing the efficiency of natural ventilation strategies in buildings. CFD is a branch of computational physics that studies the behaviour of fluids as they move from one point to another. The usage of CFD analyses in architectural design requires the input of wind environment data such as direction and velocity. Presently, this data is obtained from a weather station and there is an assumption that this data remains the same even for a building site located at a considerable distance away from the weather station. This potentially compromises the accuracy of the CFD analyses as studies have shown that due to a number of factors such the urban built form, vegetation, terrain and others, the wind environment is bound to vary from one point to another. This study sought to develop a framework that quantifies this variation and provides a way for translating the wind data obtained from a weather station to data that more accurately characterizes a local building site. With this accurate site wind data, the CFD analyses can then provide more meaningful insights into the use of natural ventilation in the process of architectural design. This newly developed framework was deployed on a study site at Virginia Tech. The findings showed that the framework was able to demonstrate that the wind flow field varies from one place to another and it also provided a way to capture this variation, ultimately, generating a wind flow field characterization that was more representative of the local conditions.

Thesis (DPhil (Psychology))—University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This dissertation examines how nurses in primary health care in South Africa make use of guidelines. Primary level health care is reliant primarily on nurses, who are under-resourced and often overwhelmed by the complex needs of their clients in the context of the TB and HIV/AIDS epidemic. Despite various continuing education strategies to promote current and evidence-based practice, there are many barriers to providing optimal care. Clinical practice guidelines using best evidence are an important tool for updating health professionals in current practice, particularly at primary care level, where busy practitioners often do not have time or sufficient access to the best evidence. Despite this, we know little of the practitioners’ experiences of guideline use. This study describes experiences of nurses in implementing clinical practice guidelines in the delivery of health care in selected primary level contexts in the Free State Province. The primary research question for this study was “What are the experiences of nurses in using guidelines in primary health care facilities?” A qualitative research approach, drawing on a psychoanalytic framework, was adopted. Three linked studies were conducted, utilising secondary data analysis of transcripts collected during the PALSA (Practical approach to Lung Health in South Africa) RCT study (sub-study 1), document description and review of guidelines used in primary care settings (sub-study 2), observation of nurses in practice and during patient consultations, and focus group discussions with nurses in primary health care facilities (sub-study 3). After the introduction of new format guidelines with onsite training and access to good support and updates, nurses reported feeling more confident, as the guidelines were explicit and gave them clear direction as to when a patient would need referral to the medical practitioner. When the guidelines were followed, and the patient responded positively to an intervention, this gave nurses a sense of credibility and validated their role as primary level health care providers. Guidelines available in the primary care clinics covered a wide variety of clinical conditions, were inconsistent, often outdated and even contradictory. A detailed comparison of two selected guidelines, the South African TB control guidelines and the PALSA PLUS guidelines, both in everyday use in the Free State province, shows that the preferences expressed by the nurses in sub-study 1 are evident in the layout, colour, and user-friendliness of the PALSA PLUS guideline. Nurses in the Free State province do use guidelines, but not consistently. Nurses make clinical judgments and decisions based on experience, alternative knowledges and intuitive responses, in consultation with colleagues and through the use of guidelines. Very few guidelines were used regularly, and each nurse had her preferences for a limited number of guidelines which she found useful. There is a clear need for integrated approaches to the information needs and support of nurses and nurse practitioners at primary care level. Guidelines play a role in promoting learning, changing professional practice and strengthening health care delivery by nurse practitioners at primary level. They can also be thought of as a strategy the health care system uses to defend against the possibility of its health professionals not meeting its expectations of providing quality care. Guidelines may contain anxiety and improve the quality of care, or compromise practice through the imposition of controls. The use of guidelines in primary care settings facilitates decision making, may contain practitioner anxiety and improve the quality of care, yet guidelines pose challenges to creative discernment of the patient’s symptoms in relation to his/her personal circumstances and may impact on the personalised holistic care approach which characterises the essence of nursing. Today’s primary care nurse and nurse practitioner needs to be a competent clinician, compassionate carer, and confident co-ordinator – the overlapping roles of caring, diagnosing and treating and managing. The challenge for the nurse in primary care is to combine her traditional caring and co-ordination role into a role which encompasses curing, caring and co-ordination, a new, yet critically important identity for the 21st century nurse. / AFRIKAANSE OPSOMMING: Die proefskrif ondersoek hoe verpleegsters in primêre gesondheidsorg in Suid-Afrika van riglyne gebruik maak. Primêre vlak gesondheidsorg steun hoofsaaklik op verpleegsters, alhoewel hulle verswelg word deur die komplekse behoeftes van hul kliënte in die konteks van die TB en HIV/AIDS epidemie. Ten spyte van verskeie volgehoue onderrigstrategieë om die huidige en bewese basiese te bevorder, is daar verskeie struikelblokke om optimale versorging te voorsien. Kliniese praktyk riglyne voorsien die beste bewyse en is 'n belangrike hulpmiddel om praktiserende professionele gesondheidswerkers, veral op die vlak van primêre gesondheidsorg, op hoogte van sake te hou. Besige programme en onvoldoende toegang tot hierdie riglyne weerhou dikwels die gesondheidswerkers van bestaande inligting. Dit is egter onbekend wat gesondheidswerkers se ondervinding en gebruik van riglyne is. Die studie beskryf versorgers se ervaring van die implementering van kliniese praktyk riglyne vir gesondheidsorg in primêre vlak kontekste in die Vrystaatprovinsie. 'n Kwalitatiewe navorsingsbenadering wat steun op 'n psigoanalitiese raamwerk, is gebruik. Drie verbandhoudende studies is gedoen wat sekondêre data analise transkripsies gebruik het wat verkry is gedurende die PALSA (Practical Approach to Lung Health in South Africa): RCT (Willekeurig Gekontroleerde Toets) studie (sub-studie 1), beskrywing van dokumentasie en oorsig van riglyne wat in primêre vlak ontwikkeling gebruik is (sub-studie 2), en observasie van verpleegsters in die praktyk en gedurende konsultasies met pasiënte, en fokusgroep besprekings met verpleegsters in primêre vlak gesondheidsorg fasiliteite (sub-studie 3). Na die bekendstelling van 'n nuwe formaat riglyne vir indiensopleiding en toegang tot goeie ondersteuning, het die verpleegsters meer selfversekerd gevoel omdat die riglyne duideliker was en aan hulle 'n beter aanduiding gegee het wanneer 'n pasiënt verwysing na 'n mediese praktisyn benodig het. Wanneer die riglyne gevolg is en die pasiënt positief op behandeling gereageer het, het dit aan hulle 'n gevoel van agting en deug vir hulle rol in primêre vlak gesondheidsorg gegee het. Beskikbare riglyne in primêre sorg klinieke dek 'n wye verskeidenheid kliniese kondisies, is onsamehangend, dikwels verouderd en selfs soms weersprekend. 'n Gedetailleerde vergelyking is tussen twee geselekteerde riglyne gedoen: die Suid-Afrikaanse TB kontrole riglyne en die PALSA PLUS riglyne. Beide word daagliks in die Vrystaatprovinsie gebruik. Die verpleegsters in sub-studie 1 het a.g.v. die uitleg, kleur en gebruikersvriendelikheid die PALSA PLUS riglyne verkies. Verpleegsters in die Vrystaat gebruik wel riglyne maar nie op 'n gereelde grondslag nie. Hulle maak eerder kliniese keuses en besluite gebaseer op ondervinding, alternatiewe kennis en intuïtiewe gevoel, in konsultasie met kollegas en na bestudering van die riglyne. Baie min riglyne is gereeld gebruik, en elke verpleegster het haar voorkeure vir 'n beperkte aantal riglyne wat sy bruikbaar vind. Daar is 'n duidelike behoefte aan 'n geïntegreerde benadering tot die informasiebehoeftes en ondersteuning aan verpleegsters en praktisyns op primêre sorg vlak. Riglyne speel 'n belangrike rol in die bevordering van onderrig, verandering van professionele praktyke en die versterking van gesondheidsorg wat deur verpleegsters in primêre vlak gesondheidsorg gelewer kan word. Dit kan ook gesien word as 'n strategie wat die gesondheidsorgsisteem kan gebruik om te verseker dat gesondheidswerkers kwaliteit diens lewer. Riglyne kan moontlik angstigheid beperk en verhoogde versorgingskwaliteit bring, of dit kan gesondheidsorg benadeel deur die afdwing van kontrolemaatreëls. Die gebruik van riglyne in primêre sorg fasiliteer besluitneming, en mag dalk angstigheid by die praktisyn beperk, wat dan die kwaliteit van versorging kan verhoog. Riglyne bied uitdagings aan die kreatiewe oordeelsvermoë om die pasiënt se simptome te sien binne die konteks van sy/haar omstandighede en mag 'n impak hê op persoonlike holistiese versorging wat die aard en kern van verpleging is. Die huidige primêre sorg verplegingspraktisyn moet 'n bekwame klinikus, ontfermende versorger en betroubare koördineerder wees – met oorvleuelende rolle van versorging, diagnosering en behandeling, en bestuur. Die uitdaging vir die verpleegster in primêre sorg is om die tradisionele versorging en koördinering te kombineer tot 'n omvattende rol van genesing, versorging en koördinasie; 'n nuwe, maar krities-belangrike identiteit vir die 21ste-eeuse versorger.
