A phenomenological investigation of pre-qualifying nursing, midwifery and social work students' perceptions of learning from patients and clients in practice settings

Government policies have emphasised the importance of patient and client involvement in all aspects of health and social care delivery, with a corresponding impetus for their involvement in the education of practitioners. Professional education programmes adopt andragogical, student-centred approaches and incorporate both academic and practice based learning and assessments. Practice experience is recognised as a crucial aspect of student learning and has become a major focus of quality reviews in health and social care education. Whilst it might seem self-evident that students on practice placements will learn from their interactions with patients and clients, this is a relatively neglected area for formal modeling, evaluation and research. This study, therefore, explores pre-qualifying nursing, midwifery and social work students’ experiences of learning from patients and clients during practice placements. The research project is underpinned by a descriptive phenomenological approach and the extensive data are analysed using phenomenological reduction (Giorgi, 1989a; 1989b). Two key themes and six categories emerged from the data. The first theme is presented as the ‘Ways of Learning’ and this comprises the categories of: facilitation of learning; critical incidents/patient stories; and role modeling. The second theme is presented as the ‘Nature of Learning’ and comprises three categories: professional ideals; professional relationships; and understanding patients’ and clients’ perspectives. It is evident that contemporary theories, including andragogy, social learning, experiential, reflective and transformative learning theories, remain relevant to professional education. The new knowledge obtained in this research is that the most powerful learning opportunities result from unplanned, informal learning opportunities involving interactions with patients and clients. However, this is not fully explained by these contemporary learning theories. This thesis will, therefore, argue that complexity theory is relevant to the requirements of professional education programmes. It will present an overarching framework to explain the data from this study and will propose strategies to harness the complexity inherent in this important aspect of student learning.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Microbiome Signatures Associated With Steatohepatitis and Moderate to Severe Fibrosis in Children With Nonalcoholic Fatty Liver Disease.

BACKGROUND & AIMS:The intestinal microbiome might affect the development and severity of nonalcoholic fatty liver disease (NAFLD). We analyzed microbiomes of children with and without NAFLD. METHODS:We performed a prospective, observational, cross-sectional study of 87 children (age range, 8-17 years) with biopsy-proven NAFLD and 37 children with obesity without NAFLD (controls). Fecal samples were collected and microbiome composition and functions were assessed using 16S ribosomal RNA amplicon sequencing and metagenomic shotgun sequencing. Microbial taxa were identified using zero-inflated negative binomial modeling. Genes contributing to bacterial pathways were identified using gene set enrichment analysis. RESULTS:Fecal microbiomes of children with NAFLD had lower α-diversity than those of control children (3.32 vs 3.52, P = .016). Fecal microbiomes from children with nonalcoholic steatohepatitis (NASH) had the lowest α-diversity (control, 3.52; NAFLD, 3.36; borderline NASH, 3.37; NASH, 2.97; P = .001). High abundance of Prevotella copri was associated with more severe fibrosis (P = .036). Genes for lipopolysaccharide biosynthesis were enriched in microbiomes from children with NASH (P < .001). Classification and regression tree model with level of alanine aminotransferase and relative abundance of the lipopolysaccharide pathway gene encoding 3-deoxy-d-manno-octulosonate 8-phosphate-phosphatase identified patients with NASH with an area under the receiver operating characteristic curve value of 0.92. Genes involved in flagellar assembly were enriched in the fecal microbiomes of patients with moderate to severe fibrosis (P < .001). Classification and regression tree models based on level of alanine aminotransferase and abundance of genes encoding flagellar biosynthesis protein had good accuracy for identifying case children with moderate to severe fibrosis (area under the receiver operating characteristic curve, 0.87). CONCLUSIONS:In an analysis of fecal microbiomes of children with NAFLD, we associated NAFLD and NASH with intestinal dysbiosis. NAFLD and its severity were associated with greater abundance of genes encoding inflammatory bacterial products. Alterations to the intestinal microbiome might contribute to the pathogenesis of NAFLD and be used as markers of disease or severity
