Haji Vahabzadeh, A. (2018). Optimal Allocation of Intensive Care Unit nurses to Patient-At-Risk-Team. Doctoral thesis, University of Auckland, Auckland.
Abstract: Explains the need for nurse-led Patient-at-Risk-Teams(PART) to prevent unnecessary ICU admissions. Investigates which nurse allocation policy between PART and ICU would result in the best outcomes for patients and hospitals. Provides econometric models to estimate the impact of critical care nurses on hospital length of stay. Proposes queueing and simulation models to obtain the optimal nurse allocation policy for minimising the ICU mortality rate. Validates proposed models at Middlemore Hospital from 2015 to 2016. Estimates the financial and mortality impact of allocating another nurse to PART per shift.

McNamara, N. (2007). The meaning of the experience for ICU nurses when a family member is critically ill: A hermeneutic phenomenologcial study. Ph.D. thesis, , .
Abstract: This study provides insight into the experience of being an ICU nurse and relative of a critically ill patient. Analysis of data from interviews of four ICU nurses who had experienced having a family member admitted to ICU brought up several themes. These included: a nurses' nightmare, knowing and not knowing, feeling torn, and gaining deeper insight and new meaning. Recommendations for organisational support for ICU nurse/relatives, and education for staff are made, based on the findings.

Rummel, L. (2001). Safeguarding the practices of nursing: The lived experience of being-as preceptor to undergraduate student nurses in acute care settings. Ph.D. thesis, , .
Abstract: This thesis used a Heideggerian Hermeneutic approach to explore the experiences of registered nurses who act as preceptors to undergraduate student nurses. The researcher interviewed fifteen volunteer registered nurses twice as preceptors to investigate their experience. The data generated was audio-taped and analysed. Four dominant themes emerged. The first, 'Becoming attuned – the call', related to registered nurses responding to the call to be preceptors to students in their clinical placement. The second, “The emerging identity of being-as preceptor: keeping the student in mind”, related to preceptors cultivating their own identity as preceptors as they worked with students in the world of nursing practice. The third, 'Assessing where the student is at: the preceptor and preceptee working and growing together', related to a constant evaluation by preceptors of students' knowledge, readiness to learn, and the provision of learning opportunities. The fourth, 'Preceptors as builders of nursing practice through teaching reality nursing', facilitated the preceptee's experience of the real world of nursing practice. An overall constitutive theme: 'Preceptors as the safeguarders of the practices of nursing', emerged as the essence of the experience.

Ryder-Lewis, M. (2004). Reliability study of the Sedation-Agitation Scale in an intensive care unit. Ph.D. thesis, , .
Abstract: This study is an extension of a previous study by Riker, Picard and Fraser (1999) to determine whether doctors and nurses rate patients similarly using the Sedation-Agitation Scale (SAS) in a natural Intensive Care Units (ICU) setting. The author notes that it is essential to establish whether these different professionals provide consistent scores and have a mutual understanding of the SAS and its constituent levels. This will help ensure that clinical decisions relating to sedation-needs can be made appropriately and consistently. This quasi-experimental reliability study was set in a 12-bed tertiary general ICU in New Zealand. The SAS had recently been introduced into this unit and a convenience sample of 42 nursing and medical staff performed paired ratings on 69 randomly selected adult ICU patients over an eight week time frame. The mean patient age was 58 years, and 79% of patients were on continuous infusions of Propofol. Intubated patients made up 91% of the sample. 74% of patients were given the same SAS score by the doctor-nurse pair. The weighted kappa score for inter-rater agreement was 0.82 indicating very good agreement. Of the 26% of scores where there was a difference, the two readings were only one score apart. Most of the difference occurred around SAS scores of 1-2 and 3-4. Further analysis found no staff or patient variables to be statistically significant in impacting on the ratings. The SAS was found to be a reliable sedation-scoring tool in a general ICU when used by nurses and doctors of varying experience.

Abstract: The author explores possible approaches to the ethical dilemma confronting nurses of critically ill premature infants with an uncertain or futile outcome despite aggressive neonatal intensive care. A case history illustrates the issues. The morality of nursing decisions based on deontological and utilitarian principles is examined, as are the concepts of beneficence and non-maleficence. A fusion of virtue ethics and the ethic of care is suggested as appropriate for ethical decision-making in the neonatal intensive care environment.

Abstract: This article describes the care of a brain-dead intensive care unit patient. The human caring theory of Jean Watson is used to interpret the interactions between family, patient and nurse in this case study. Watson's concepts of care are examined as they relate to each stage of caring for the patient and his family.

Evans-Murray, A. (2004). Meeting the needs of grieving relatives. Kai Tiaki: Nursing New Zealand, 10(9), 18–20.
Abstract: This article examines the role of nurses working in intensive care units who may need to work with families as they face the death of a loved one. How the nurse communicates with relatives during these crucial hours prior to the death can have profound implications on their grief recovery. Universal needs for families in this situation have been identified in the literature, and include: hope; knowing that staff care about their loved one; and having honest information about their loved one's condition. A case study is used to illustrate key skills and techniques nurses can employ to help meet these universal needs. In the first stage of grief the bereaved is in shock and may feel a sense of numbness and denial. The bereaved may feel confused and will have difficulty concentrating and remembering instructions, and they may express strong emotions. Studies on families' needs show that honest answers to questions and information about their loved one are extremely important. It is often very difficult for the nurse to give honest information when the prognosis is poor. Good communication skills and techniques are discussed, in which hope is not offered at the expense of truthfulness, and the nurse facilitates the process of saying goodbye and expressing emotions. Practical techniques, such as including the family in basic care such as foot massaging and simple hygiene routines, may also be used to move the family from being bystanders to the impending death, to comforters.

Rose, L., Nelson, S., Johnston, L., & Presneill, J. J. (2008). Workforce profile, organisation structure and role responsibility for ventilation and weaning practices in Australia and New Zealand intensive care units. Journal of Clinical Nursing, 17(8), 1035–1043.
Abstract: The aim of this research is to provide an analysis of the scope of nursing practice and inter-professional role responsibility for ventilatory decision-making in Australian and New Zealand intensive care units (ICU). Self-administered questionnaires were sent to nurse managers of eligible ICUs within Australia and New Zealand. Survey responses were available from 54/180 ICUs. The majority (71%) were located within metropolitan areas and categorised as a tertiary level ICU (50%). The mean number of nurses employed per ICU bed was 4.7 in Australia and 4.2 in New Zealand, with 69% (IQR: 47-80%) of nurses holding a postgraduate specialty qualification. All units reported a 1:1 nurse-to-patient ratio for ventilated patients with 71% reporting a 1:2 nurse-to-patient ratio for non- ventilated patients. Key ventilator decisions, including assessment of weaning and extubation readiness, were reported as predominantly made by nurses and doctors in collaboration. Overall, nurses described high levels of autonomy and influence in ventilator decision-making. Decisions to change ventilator settings, including FiO(2) (91%, 95% CI: 80-97), ventilator rate (65%, 95% CI: 51-77) and pressure support adjustment (57%, 95% CI: 43-71), were made independently by nurses. The authors conclude that the results of the survey suggest that, within the Australian and New Zealand context, nurses participate actively in ventilation and weaning decisions. In addition, they suggest, the results support an association between the education profile and skill-mix of nurses and the level of collaborative practice in ICU.

Tweed, C., & Tweed, M. (2008). Intensive care nurses' knowledge of pressure ulcers: Development of an assessment tool and effect of an educational program. American Journal of Critical Care, 17(4), 338–347.
Abstract: The aim of this study was to assess intensive care nurses' knowledge of pressure ulcers and the impact of an educational programme on knowledge levels. A knowledge assessment test was developed. A cohort of registered nurses in a tertiary referral hospital in New Zealand had knowledge assessed three times: before an educational programme, within two weeks after the programme, and 20 weeks later. Completion of the educational programme resulted in improved levels of knowledge. Mean scores on the assessment test were 84% at baseline and 89% following the educational programme. The mean baseline score did not differ significantly from the mean 20-week follow-up score of 85%. No association was detected between demographic data and test scores. Content validity and standard setting were verified by using a variety of methods. Levels of knowledge to prevent and manage pressure ulcers were good initially and improved with an educational programme, but soon returned to baseline.

Abstract: The author presents research on nursing strategies that reduce the psychological effects of critical illness and prevent the intensive care unit (ICU) atmosphere from adversely affecting the nurse-patient relationship. Post-traumatic stress disorder and other phobic anxiety syndromes are noted as a risk among former ICU patients. Four interventions to put in place for discharge are presented: patient-centred nursing, communication, multidisciplinary care, and patient/family education.

Abstract: Discontinuation of life support measures for an extremely low birthweight or very premature baby is controversial and difficult for both the parents and the healthcare professional involved in caring for the infant. This study seeks to investigate the attitude of nurses and midwives to the withdrawal of care from sick neonates. Part 1 reviewed the literature on this subject. Part 2 reports the results of a survey carried out in a New Zealand NICU.
