M.Cur. / The purpose of this study was to describe the clinical competencies of the shift leader in the ICU setting in order to determine if there is a gap between what is expected of the shift leader and what is happening in reality. A quantitative, descriptive design was used and cluster sampling implemented. A survey, utilizing questionnaires, was used to gather data from three clusters, comprising 11 hospitals from a single private healthcare group. 251 questionnaires were distributed and 98 were returned, indicating a response rate of 39%. Validity and reliability were ensured. Results indicated that respondents classified the majority of competencies as essential competencies. None were classified as critical competencies and only four were classified as specific competencies. Shift leaders were viewed as competent by all respondents in all three clusters. Results were used to describe a typology of the competencies of the shift leader in the ICU setting.

M.Cur. / In the cardiothoracic critical care unit, the respiratory management, post-extubation forms an important component of the total nursing care of the patient. To ensure optimal respiratory management the critical care nurse needs guidelines through which quality and continuity of nursing care can be ensured. Through the effective management of the respiratory system of the patient the critical care nurse contributes to maintaining, promoting and restoring health. In this way the critical care nurse facilitates the patient's strive towards reaching his/her objective of obtaining wholeness and he/she obtains his/her objective of quality nursing. The aim of this study is to formulate guidelines for the respiratory mangement of the cardiothoracic patient, post-extubation. A qualitative-descriptive contextual spesific reseach was followed in which a focus group interview, the opinions of field specialists and the deductive analysis of a literture study were used to formulate guidelines for the respiratory management of the cardiothoracic patient, post-extubation. An analysis was done through which the focus group interview was coded and categories were formulated. These main categories and subcategories were then further explored and described by the literature and by die opinions of the field specialists. The guidelines which were formulated must relieve the uncertainty that exists among different critical care nurses and it must ensure continuity of nursing care. After the guideliness have been established to promote the nursing practice recommendations were made for nursing practice, nursing education and for further research.

M.Cur. / The intra-aortic balloon pump is a volume displacement device that is used to provide partial support to the left ventricle. The IABP is an effective and general used circulatory support device. The nursing of a patient on IABP therapy requires demonstration of specific clinical competence by the critical care nurse. Clinical competence is defined as the ability of the critical care nurse to integrate his/her knowledge, skills and values and to demonstrate it during nursing of a patient on IABP with the aim to promote the patient's health. The aim of this research had been to evaluate the clinical competence of the critical care nurse during the nursing of a patient on IABP, and to make recommendations according to that regarding education, the practice and research. The relationship between the components of clinical competence namely knowledge, skills and values that were set as aim, were also established. A quantitative, contextual, descriptive, correlational research design had been used in the study to compile a self-developed evaluation instrument that had been used to evaluate the clinical competence of the critical care nurse. The evaluation instrument consisted of a questionnaire that evaluated the knowledge of the critical care nurse, a check list that evaluated the skills of the critical care nurse and a semantic differential scale that evaluated the values of the critical care nurse during the nursing of a patient on IABP therapy. After the data was analyzed, it appeared that critical care nurses don't possess the necessary knowledge and skills to nurse patients on IABP, and as such are not clinically competent to nurse patients on IABP. iii Recommendations were made regarding education, the practice and research in order to improve the clinical competence of critical care nurses during the nursing of a patient on IABP therapy

M.Cur. / The nursing service manager is accountable for the managerial outputs of the nursing service, being quality nursing care, cost effectiveness and quality nursing staff management. These managerial responsibilities will influence the overall management efficiency of the health delivery system. There is a need for a more scientific basis of staffing in South African critical care units. Various methods are used to determine staffing needs, but the most accurate and acceptable method being used is the patient classification system. The success of a critical care patient classification system is based upon the accurate determination of the ideal nurse-patient ratio. Ideal nursepatient ratio depends on matching the competency of the critical care nurse to the severity of the critical care patient's illness. Internationally and nationally very few guidelines describe the competency requirements that the critical care nurse should have to function effectively in the critical care unit. To maintain a high standard of quality nursing care, the critical care nurse should be assigned to a critical care patient according to her competency level. The aim of this study was to describe a scientific patient classification system for critical care patients according to which workload and nursing requirements can be ascertained. Secondly, to describe guidelines for the competency requirements of a registered critical care nurse assigned to nurse the different categories of critical care patients categorised by the patient classification system as prescribed. The aim of the study is justified by means of an exploratory, descriptive, contextual research design. A critical care patient classification system has been developed and validated by a group of critical care nursing experts using a structured two phase research method. The statistical validity of each item of the critical care patient classification system was determined by means of a content validity index. All the items of the critical care patient classification system were rated as valid and therefore the critical care patient classification system as a whole has been accepted as valid. The reliability of the critical care patient classification system was tested by means of a pilot study in two selected research units. It was determined that the inter-rater reliability was within the 95 per cent confidence interval, that the system could discriminate between different critical care patients and nurse-patient ratios were effectively determined by the system. Critical care nurse competency requirements were identified by critical care nursing experts by means of a focus group interview. The results obtained from the focus group interview were verified by a literature control and peer group review. Guidelines for the competency requirements of the critical care nurse were compiled. The critical care patient classification system developed will equip the critical care manager with a scientific instrument to assign personnel to critical care units. The critical care patient classification system will furthermore assist the critical care unit manager in the daily utilisation of valuable human resources, in that critical care nurses with the appropriate level of expertise can be assigned to each patient, thus facilitating quality critical care nursing.
