Critical thinking : perspectives and experiences of critical care nurses

[摘要] ENGLISH ABSTRACT: The increasingly complex role of the critical care nurse in an intensive care environment demands a much higher level of critical thinking and clinical judgment skill than ever before. Critical thinking in nursing practice may be defined as the cognitive ability to analyse, predict and transform knowledge, ensuring quality nursing care. To reason from a nurse's perspective requires that we learn the content of nursing; this includes the concepts, ideas and theories of nursing. The aim and objectives of the study were to explore critical care nurses' perspectives and experiences with regards to the concept of critical thinking, facets influencing the application of critical thinking skills in clinical practice and how these impact on the delivery of quality nursing care.A qualitative approach, using a case study design was utilised. A sample of six participants, who met the study inclusion criteria and consented to participate, were interviewed individually. Subsequently, five of these six participants took part in a focus group discussion to capture additional data to clarify and enrich the individual interview data. A field worker was present during the interviewing processes to note non-verbal data and later verify transcribed data.Feasibility of the proposed study was established by conducting a pretest which elicited relevant information. Ethical approval for the study was obtained from the Health Research Ethics Committee at the Faculty of Medicine and Health Sciences, Stellenbosch University. Permission and consent was obtained from the relevant hospital group to interview nurses working in the intensive care units.Qualitative content analysis, which focuses on the content or contextual meaning, was used to analyse interview data. Coding of the data through emergent themes and sub-themes was done by the researcher and supported through independent coding to verify and strengthen the analysis and interpretation of the researcher. .The results depicted how the participants personally understood the concept of critical thinking and the components influencing the application of critical thinking skill in clinical practice. The study of the participants' perspective of the concept of critical thinking and portrayed how they experience analytical and independent thinking, competence and confidence, as well as knowledge, skill and expertise, to influence the quality of patient care.The data revealed several themes that facilitated critical thinking in critical care nurses. These themes were 'team support', 'experience and exposure' and 'empowering the mind'. Emergent themes elaborating the limitations of critical thinking included 'being stressed', 'professional boundaries' and 'being busy'.Several recommendations and suggestions for future research were offered.
