An important aspect of qualitative research is reaching saturation-loosely, a point at which observing more data will not lead to discovery of more information related to the research questions. However, there has been no validated means of objectively establishing saturation. This article proposes a novel quantitative approach to measuring thematic saturation based on a sound statistical model. The model is validated on two data sets from different qualitative research projects involving interviews, focus groups, and literature surveys. The proposed model provides consistent estimates of saturation across data sets, within branches of data sets, and over the course of a research project. The model can be used for both quantifying saturation and estimating the number of observations required to achieve a specified level of saturation.

This article proposes a strategic framework or road map for sustainable m-health. The drivers and critical success factors of this framework are identified from the literature and a survey of the views of senior strategists in the New Zealand health sector. The success factors are associated with key tasks in the framework that identify suitable applications, channel development activity, and confirm activity by continued support of innovation whilst moving successful applications into the mainstream. The two most important outcomes from the research are that m-health has a crucial, even inevitable, role to play in future healthcare, and the development and exploitation of m-health demands a top-down strategy or framework to match and encourage bottom-up innovation by healthcare practioners. Without such a strategy to guide (but not direct) innovation, many otherwise valuable advances will not be sustainable and resources will be wasted on questionable applications that will slow development and reduce credibility.

An overview is provided of education and training in health information management in the context of national information strategies. Although the article focuses upon British programmes, there are examples from North America, Australasia and other countries. Reference is made to international activities in the development of generic courses for education and training, the need for education and training, the content of courses, and methods of delivery, including Internet-based training and education. Governments and health authorities in many countries have recognized the urgent need for a highly educated and trained workforce in information management, but universities have been slow to respond, until the last few years. However, there is now a plethora of education and training programmes in North America, most European countries, and Australasia.

This paper outlines the roles of health informatics in modern health planning and delivery and defines the key challenges and opportunities for promoting high-quality and cost-effective care. It describes the main information management and technology drivers that improve the generation, use and flow of health information, categorizing these drivers under the headings of healthcare complexity, policy and priorities, clinical support and technology. The discussion draw attention to the ethical and legal issues associated with the drivers and summarizes the general features of these issues as they arise from computer-mediated medicine.
