Abstract: This dissertation explores the assessment of nurses' clinical competence in the adult ICU setting. Specifically, methods for the assessment of competence are critiqued for their practical application to the novice nurse with less than six months experience in ICU. The assessment methods considered are continuous clinical assessment, self-assessment, peer review, objective structured clinical examination (OSCE), portfolio and computer assisted assessment. Several criteria are applied to the methods including the ability of each method to assess skills, knowledge and attitudes or values. Each method is critiqued for its implications in terms of cost and staffing resource, benefits and barriers to implementation. In addition, reliability and validity issues are considered for each method. The outcome of this exploration is the recommendation of a combination of methods; namely, portfolio and OSCE, for the assessment of competence in the ICU novice. The author concludes that this finding enhances current understanding within the ICU specialty of the multidimensional nature of competence assessment.

Abstract: This study explores how registered nurses working within the acute surgical ward environment of a New Zealand hospital communicate changes in a patient's condition. The purpose of this research study was to examine the processes, communication techniques and behaviours that nurses use, in order to determine the critical requirements for registered nurses to effectively communicate changes in patients' conditions to doctors. The critical incident technique developed by Flanagan (1954) was adapted and used to explore incidents that occurred when six registered nurses working in acute surgical wards communicated a change in a patient's condition to a doctor. Communication is an integral part of everyday activity. This study has shown an assessment process occurs before communication can take place. A nurse's concern for a patient's condition initiates the assessment process. A judgement is formed from the nurse's concern that a patient's condition has changed. Judgements take into account multiple ways of knowing including pattern recognition, empirical knowing and intuition. Institutional protocols also affect judgements and the ability of a nurse to ensure support is received for the patient's well being. The communication process is initiated for two reasons, to support the patient, and to support the nurse in providing care for the patient. Significant in determining the need for support is the action required that might be outside the nurse's scope of practice. The response should address the nurse's concern and take into account the importance of the relationship, trust between all parties, respect of each other's positions and knowing team members and their capabilities. Understanding these aspects of the communication process should enhance nurses and doctors abilities to effectively communicate regarding a change in a patient's condition.

Abstract: A retrospective descriptive design was used to examine the records of all presentations to the emergency department of patients with COPD over a 3-month period to determine whether there is a subset group of people who present with hypercarbia. There were 114 presentations, amongst those there were 71 individuals, a number presenting more than once within the three months. 80% of the 71 individuals had a smoking history of which 53% were female. Of the 114 presentations, 76 had arterial blood gases taken during their emergency department presentation. Of these 76 presentations 30 had hypercarbia and 46 were non-hypercarbia. These 76 presentations involved 58 individuals, with some individuals presenting five times over the three-month period. Three groups emerged, some who were only hypercarbia (n= 18), some in the non-hypercarbia group (n=35) and 5 individuals who had presentations in both the hypercarbia and non-hypercarbia groups. Data showed that there was no definable subset group of hypercarbia patients within acute exacerbations of COPD presenting to the emergency department according to the variables. However the sample of presentations (with a blood gas) found within the study suffering hypercarbia was much higher (31.1%) than anticipated. Further analysis showed that the hypercarbia group had a significant lower forced expiratory volume in one second (FEV1) and a combination diagnosis of emphysema or asthma and congestive heart failure. An implication to the clinician is that identification of hypercarbia within COPD exacerbation is problematically difficult until the late signs are shown with the individual. By that time effective treatment patterns may have changed from the initial presenting problem. The author concludes that future areas of research within this field needs to lie within the community, and look at when these people start the exacerbation, what leads them to progression presentation to the emergency department, and whether these people are chronic sufferers of hypercarbia or presenting after a period of days exacerbation within their own home.
