According to Sousa & Voss (2006), “A virtual channel refers to a means of communication using advanced telecommunications, information, and multimedia technologies” . In this study, we focus on mobile health services ( mHealth) , which is defined as an interactive medical service over a mobile platform ( e.g., mobile phone , PDA ) containing both virtual ( e.g., e referral, e prescription etc.) and physical service components ( e.g., treatment consultation with doctors) ( see Exhibit 1). mHealth is seen as a transformative service for shifting the care paradigm from crisis intervention to promoting wellness, prevention, and self management (Ostrom et al. 2010; Kaplan & Litewka 2008). Though mHealth is transforming healthcare delivery around the world; however, there are growing concerns about the p...

Using a literature review, the Australian National Guidelines for Type 2 Diabetes Mellitus (T2DM), SNOMED-CT-AU and input from health professionals, we developed a Diabetes Mellitus Ontology (DMO) to diagnose and manage patients with diabetes. This paper describes the manual validation of the DMO-based approach using real world EHR data from a general practice (n=908 active patients) participating in the electronic Practice Based Research Network (ePBRN). The DMO-based algorithm to query, using Semantic Protocol and RDF Query Language (SPARQL), the structured fields in the ePBRN data repository were iteratively tested and refined. The accuracy of the final DMO-based algorithm was validated with a manual audit of the general practice EHR. ...

This paper explores ways to improve clinical outcomes by linking different multiple datasets held in a diverse set of clinical, research and other repositories in many different organisations. This research aims to realise this potential by identifying the most effective ways to utilise the growing amount of data generated by cancer care information systems through improved data linkage and application of big data and emerging business intelligence applications. Given the growing number and sophistication of big data in health initiatives and the insights that current big data researchers are producing, the issue of how well they are taken up and applied by clinicians becomes more important. For that reason, this paper aims to realise this potential by researching the most effective ways for clinicians to utilise the growing amount of data generated by cancer care information systems.
Improving Health Management through Clinical Decision Support Systems

The data stored or captured in EHRs are diverse and include demographics, billing, medications, and laboratory reports; and can be categorized as structured, semi-structured and unstructured data. Various data and text mining techniques have been used to extract these data from EHRs for use in decision support, quality improvement and research. Mining EHRs has been used to identify cohorts, correlated phenotypes in genome-wide association studies, disease correlations and risk factors, drug-drug interactions, and to improve health services. However, mining EHR data is a challenge with many issues and barriers. The aim of this chapter is to discuss how data and text mining techniques may guide and support the building of improved clinical decision support systems.

We started with management theories, and then described and analyzed e-business models. This was followed by a discussion of e-business management issues and evolving techniques for ebusiness management solutions. Most examples were given from the ebusiness domain in general, and from the telecommunication sector in particular. We highlighted the fact that a business service had to be defined and measured through business level parameters. Although we discussed the framework based on Service Level Agreements (SLA), it was not clear how qualitative service parameters could be quantified and measured to track a business service performance. Therefore, some of the questions may be formulated as: How to define e-business management specifications irrespective of the type of e-business (e.g., book publishing, travel service, e-commerce, ehealthcare, or e-government)? How can an e-business management solution be designed from scratch? How are qualitative business service parameters translated to measurable, quantitative parameters? How do we breakdown the complexity of such a design and deployment process?

Implementation of e-business management is complex due to the interplay of a range of associated factors, such as network management, systems management, and application management. It is important to integrate management process models, such as help desk with platforms for integrated management. Hence the discussion of the operation and implementation of e-business management may be broken into the following categories to facilitate understanding: Realization of the service perspective of e-business management as discussed in this chapter Realization of the infrastructure perspective (including network and systems management) as discussed in Part 4 (Chapter 7) of this book

To integrate these different paradigms it is necessary to think about the interoperability of different standards and technologies. Integration and interoperability of ebusiness management may be considered with respect to the following dimensions: – Types of business (healthcare, telecommunications, finance etc.) – Functions

The increasing distribution of management resources (including people) necessitates groupware/workflow-integrated enterprise-wide solutions for network management. The design of network management systems involves the cooperation of multiple groups of people within and across organisations. Hence it may be useful to adopt a formal design methodology. However, such a methodology needs to be flexible enough to accommodate a wide variety of design models and notations in this multidisciplinary area of research. This paper presents a new methodology (called CoMEN-cooperative management methodology for enterprise networks) for the design and implementation of enterprise-oriented network management solutions

The elderly enjoy being reminded about past experience and having conversations about their life history. However, there are common reports of frustration that carers do not know the elderly person in the way they family do. Further, with staff turnover, it is difficult for a single staff member to provide meaningful conversations about the older person’s life history. In this paper we describe possibilities for technology advances using avatars and robots to provide this service. An elderly person or her/his family could answer questions regarding past experiences. This could involve family, care staff or students on placements. Answers to the questions are compiled into a composite view of the person’s experiences. An avatar could use this knowledge to converse with the elderly person in a meaningful way. Possible benefits are that the process may enhance family involvement and personalized care that does not require additional resources or specialised skills. The same knowledge could be inserted into a humanoid robot whereby the robot converses with the elder person. In this presentation we provide an example of story-capture and a conversation with the avatar. We discuss the efficacy of the approach and compare it with the possibilities of using a humanoid robot in engaging older people in conversations about their past.

The size of information received in a day now is larger than what you have
