Clinical learning experiences form an integral part of the student nurse's training, for it is in the clinical setting that students acquire the knowledge, skills and values necessary for professional practice. The purpose of this research was to explore student nurses experiences during clinical practice. A qualitative, exploratory, descriptive and contextual design was utilised, employing the phenomenological method. Unstructured interviews were conducted with student nurses in their final year of the four year nursing programme at a nursing college campus in the Limpopo Province. Tesch's method of data analysis was used. The findings indicate that there are aspects which impact negatively on student nurses' clinical learning experiences, such as lack of teaching and learning support, lack of opportunities for learning, poor theory-practice integration, and poor interpersonal relationships between the students, college tutors and ward staff. Recommendations to enhance the clinical learning experiences of student nurses were made. / Health Studies / M.A. (Health Studies)

Clinical practice is the core of nursing education during which the student is socialized into the nursing profession. During this period, there is transfer of knowledge and skill from qualified nurses and other members of the multidisciplinary team to student nurses. The purpose of this study is to describe and explore student nurse’s experiences of clinical accompaniment in a public hospital in Gauteng Province by means of a qualitative approach that included the exploratory, descriptive and contextual study. Three focus group interviews were conducted with students and one with clinical accompanists. Qualitative methods included categorizing and coding. The major findings of the research revealed that participants regarded relationships and communication as important for clinical accompaniment. Both student nurses and unit supervisors expected nurse facilitators to accompany students in clinical settings; but some hospital staff members did not perceive clinical accompaniment to be their task. / Health Studies / M.A. (Public Health)

The purpose of the study was to explore the perceptions of professional nurses on student mentorship. A qualitative, explorative, hermeneutic phenomenological research was conducted to determine the meaning of mentoring as perceived by professional nurses and to identify the successes and challenges encountered by professional nurses with regard to student mentorship during clinical practice. A face-to-face semi-structured interviews were done to collect data from operational managers (n=16) who were managing all unit activities, student mentoring included. Each interview lasted for ± 45 minutes. A hermeneutic data analysis (hermeneutic circle) was followed for data analysis. Four (4) themes and 15 sub-themes emerged from data collected from operational managers. The findings revealed that mentoring was perceived as a valuable phenomenon to apply in the preparation of student nurses for future professional role. In the process of mentoring, the caring attitude is revealed. Factors found to drive mentoring process successful was amongst other commitment, interest and partnership which guarantee the mutual efforts to the process. Though it is beneficial to mentor, mentee and the organisation as according to findings, challenges were also seen impacting on this process limiting its intentions / Health Studies / M.A. (Health Studies)

Schizophrenia is a complex disorder affecting 1% of the population and is highly heritable, but the majority of contributing genetic factors has remained elusive. Current risk estimates for clinical practice are primarily determined by family history and associated empirical risk. Copy number variants (CNVs) may hold the key to explaining the missing heritability in schizophrenia research; schizophrenia risk estimates as high as 30% have been found for the most-studied CNV associated with schizophrenia, 22q11. Currently, there are methods to identify CNVs though previously collected data from SNP microarrays that would facilitate these types of studies. To determine if algorithms that call CNVs from microarray data are robust four genomic regions with putative CNVs called by the Wellcome Trust Consortium using Birdseye in Birdsuite with Affymetrix 6.0 array raw SNP intensities, primarily affecting genes CHD1L, COX5B, PAK7, ZFYVE20, were validated using Taqman real-time qPCR assays in 29 samples by research groups at VCU and Dublin. CNVs called from the algorithm were 100% validated at VCU though there were false negatives from the algorithm that were validated. Two samples at loci with putative duplications were not called by the Dublin group, which may be because of differing sensitivities of the Taqman assays to be able to detect a 50% difference in copy number between duplications and diploid controls, or because of another technical or analytical difference between the two sites. Deletion frequency of one common CNV found in the gene ERBB4, was assessed by qPCR in both Irish singleton (ICCSS) and Irish family (IHDSF) samples and compared with Irish control (Trinity Biobank) and North American control populations. The ERBB4 deletion frequency was not significantly different when comparing the Irish controls to the Irish singleton or the Irish family samples though the family samples were different when compared against the North American control population, which suggests population stratification, rather than a true association between ERBB4 and increased schizophrenia risk. Current clinical practice has been improved by knowledge and evaluation of CNV-related disorders that include risk for psychosis and additional phenotypes. Genotyping of individuals with known psychosis has led to improved patient care for non-psychosis-related phenotypes associated with CNVs. Individuals with suspected genomic disorders that are found to have CNVs can be counseled on potential psychosis risk and potential risk to their offspring. Recurrent CNVs may hold promise in future clinical practice in order to individualize risk estimates in the general patient population, and increase the number of individuals able to receive anticipatory treatment to minimize disease severity.

Les connaissances décisionnelles sont un type particulier de connaissances dont le but est de décrire des processus de prise de décision. En cancérologie, ces connaissances sont généralement regroupées dans des guides de bonnes pratiques cliniques. Leur publication est assurée par des organismes médicaux suite à un processus d'édition collaboratif complexe. L'informatisation des guides a conduit à la volonté de formaliser l'ensemble des connaissances contenues de manière à pouvoir alimenter des systèmes d'aide à la décision. Ainsi, leur édition peut être vue comme une problématique d'acquisition des connaissances. Dans ce contexte, le but de cette thèse est de proposer des méthodes et des outils permettant de factoriser l'édition des guides et leur formalisation. Le premier apport de cette thèse est l'intégration des technologies du Web social et sémantique dans le processus d'édition. La création du wiki sémantique OncoLogiK a permis de mettre en oeuvre cette proposition. Ainsi, un retour d'expérience et des méthodes sont présentés pour la migration depuis une solution Web statique. Le deuxième apport consiste à proposer une solution pour exploiter les connaissances décisionnelles présentes dans les guides. Ainsi, le framework KCATOS définit un langage d'arbres de décision simple pour lequel une traduction reposant sur les technologies du Web sémantique est développée. KCATOS propose en outre un éditeur d'arbres, permettant l'édition collaborative en ligne. Le troisième apport consiste à concilier dans un même système les approches pour la création des guides de bonnes pratiques informatisés : l'approche s'appuyant sur les connaissances symbolisée par KCATOS et l'approche documentaire d'OncoLogiK. Leur fonctionnement conjoint permet de proposer une solution bénéficiant des avantages des deux approches. De nombreuses perspectives sont exposées. La plupart d'entre elles visent à améliorer les services aux utilisateurs et l'expressivité de la base de connaissances. En prenant en compte le travail effectué et les perspectives, un modèle réaliste visant à faire du projet Kasimir un système d'aide à la décision complet est proposé / Decision knowledge is a particular type of knowledge that aims at describing the processes of decision making. In oncology, this knowledge is generally grouped into clinical practice guidelines. The publication of the guidelines is provided by medical organizations as a result of complex collaborative editing processes. The computerization of guides has led to the desire of formalizing the knowledge so as to supply decision-support systems. Thus, editing can be seen as a knowledge acquisition issue. In this context, this thesis aims at proposing methods and tools for factorizing editing guides and their formalization. The first contribute on of this thesis is the integration of social semantic web technologies in the editing process. The creation of the semantic wiki OncoLogiK allows to implement this proposal. Thus, a feedback and methods are presented for the migration from a static web solution. The second contribution consists in a solution to exploit the knowledge present in the decision-making guides. Thus, KcatoS framework defines a simple decision tree language for which a translation based on semantic web technologies is developed. KcatoS also proposes an editor of trees, allowing collaborative editing online. The third contribution is to combine in a single system approaches for the creation of clinical guidelines: the approach based on the knowledge symbolized by KcatoS and the documentary approach symbolized by OncoLogiK. Their joint operation can propose a solution benefiting from the advantages of both approaches. Many future works are proposed. Most of them aim at improving services to users and the expressiveness of the knowledge base. Taking into account the work and prospects, a realistic model to create a decision-support system based on clinical guidelines is proposed

It comprises both the account of her personal path in psychoanalytic formation and the problematization of the relations between theoretical and technical devices and experience in this learning process. The account is based on session records, supervision records, recollections and impressions brought about by these records and the theoretical referential of Freudian and post Freudian psychoanalysis. The analyses and discoveries about the difficulties and conflicts present on the learning path of psychoanalytic practice engendered a process of de-idealization of both the practice itself and the value of truth of the theoretical and technical formulations of the pioneers of this métier. The conduction of clinical practice is revealed to be based on an ethical referential, in the sense of sheltering both the afflicted alterity and the afflicted other / O presente trabalho procura identificar e analisar algumas dificuldades e conflitos vivenciados pela autora ao longo do processo de aprendizagem da prática psicanalítica. Apresentam-se a narrativa do percurso pessoal de formação em psicanálise e a problematização das relações entre os aparatos teórico-técnicos norteadores do ofício da clínica e as experiências vividas nesse processo de aprendizagem. A construção da narrativa tem como suportes relatos de sessões, relatos de supervisões, memórias e impressões evocadas por esses registros e o referencial teórico da psicanálise freudiana e pós-freudiana. O trabalho de análises e descobertas acerca das dificuldades e conflitos presentes na caminhada de aprendizagem da prática psicanalítica engendrou um processo de desidealização, tanto da prática, quanto do valor de verdade das formulações teóricas e técnicas dos pioneiros no ofício da clínica. Desvela-se o encaminhamento do exercício da clínica pautado em um referencial ético, no sentido do acolhimento da alteridade e do outro em sofrimento

A lack of consistent, evidence-based practices for blood lead testing of children existed in a local public health department (LHD). No known blood lead level is safe, and toxicity can result in behavioral and cognitive impairments. The purpose of this project was to develop and analyze a clinical practice guideline to establish blood lead testing procedures in the LHD to improve testing procedures and enhance future testing within the jurisdiction. The RE-AIM framework was used to address the reach, effectiveness, adoption, implementation, and maintenance of the clinical practice guideline. Five experts evaluated the guideline using the Appraisal of Guidelines for Research and Evaluation instrument. The assessment results indicated 96.4% agreement across all domains. The experts agreed unanimously to recommend adoption of the clinical practice guideline. Implementation of the guideline might advance nursing practice and patient care in the LHD through incorporation of evidence-based practices. Implementation might also lead to early identification of lead-burdened children and may provide the opportunity for treatment to mitigate cognitive and behavioral deficits related to lead toxicity, thereby improving child health and decreasing related health care costs. Engagement of the clinical practice guideline will support positive social change through the empowerment of public health nurses to provide optimal care to a population of children at risk of deleterious and long-term side effects of lead exposure.

Residents in nursing facilities are more prone to falls than those living in the community. Injuries resulting from falls impact residents, their families, and healthcare costs. The gap in nursing practice was the lack of a comprehensive fall-prevention program in a long-term care facility that had experienced high fall rates among residents. This project addressed whether an educational program using the American Medical Directors Association's clinical practice guideline and the Centers for Disease Control and Prevention's STEADI (Stopping Elderly Accidents, Deaths, & Injuries) toolkit for fall- prevention improved the self-efficacy of direct-care staff in preventing falls among residents in a long-term care facility. The practice-focused question focused on whether education on the use of an integrated multifactorial fall-prevention guideline would increase confidence of long-term care staff in reducing falls in long-term care residents. The evaluation used the 11-item Self-Efficacy for Preventing Falls-Nurse scale for 5 licensed nursing staff and the 8-item Self-Efficacy for Preventing Falls-Assistant scale for 21 nursing assistants. The positive change in self-efficacy scores of nurses and nursing assistants after the education program was greatest for face-to-face team communication regarding fall risk and individual resident prevention plans. The use of best-practice guidelines that improve fall risk-assessment and use of fall precautions to decrease the number of falls and falls with injury has the potential to bring about positive social change by improving the nursing care of nursing home residents, resulting in improved resident safety and quality of life.
