Watson, P., B. (2010). Positive pressure intravenous access ports on central venous devices in children: An evidence-based review. Kai Tiaki Nursing Research, 1(1), 12–18.
Abstract: This research aimed to assess the evidence for benefits and risks of positive pressure mechanical valve (PPMV) intravenous access ports on central nervous system devices (CVADs) in children. PPMVs on CVADs have been promoted as preventing occlusion and the need for heparin flushing. A search for primary research to March 2010 was conducted using MEDLINE, EMBASE and CINAHL. There is sufficient evidence that some models of PPMV intravenous access ports on CVADs, when flushed with normal saline, are associated with increased bloodstream infections in children. Further research is required.

Gibbons, V., Rice, S., & Lawrenson, R. (2010). Routine and rigidity: Barriers to insulin initiation in patients with Type 2 Diabetes. Kai Tiaki Nursing Research, 1(1), 19–22.
Abstract: It has been shown that intensive management of diabetes with type 2 diabetes is effective and has led to wider use of insulin. The conversion of patients from oral medication to insulin is usually managed in primary care. The study discussed here aimed to explore how patients with type 2 diabetes mellitus (T2DM) perceived insulin. The study waa conducted in 2009 in an urban general practice in a large town in New Zealand with more than 300 patients with type 2 diabetes. A qualitative study was conducted with face-to-face interviews with 13 participants. The question focused on insulin initiation, lifestyle and routine. The transcribed responses were subject to thematic anaylsis. Interviews showed participants felt restricted by the prospect and eventuality of the routine and restrictions of being on insulin. Results show there needs to be a greater emphasis on the disease being progressive. This study provides the ground work for developing resources that will benefit patients with T2DM.

Honey, M. L. L. (2010). Methodological issues with case study research. Kai Tiaki Nursing Research, 1(1), 9–11.
Abstract: Case study research, as a qualitative methodology, attracts some criticism, especially related to rigour, reliability and validity. A New Zealand-based study that explored complex phenomena – flexible learning for postgraduate nurses – provides a practical example of how the case study design can address these criticisms. Through describing the mixed methods used, different sources and methods of data collection, and data analysis, the process of achieving data quality and trustworthiness are highlighted.
