Preliminary investigation at the beginning of this research showed that informatics on point-of-care (POC) devices was limited to basic data generation and processing. This thesis is based on publications of several studies during the course of the research. The aim of the research is to model and analyse information generation and exchange in telehealth systems and to identify and analyse the capabilities of these systems in managing chronic diseases which utilise point-of-care devices. The objectives to meet the aim are as follows: (i) to review the state-of-the-art in informatics and decision support on point-of-care devices. (ii) to assess the current level of servitization of POC devices used within the home environment. (iii) to identify current models of information generation and exchange for POC devices using a telehealth pers...

Aim: The aim of the paper was to identify the models of information exchange for UKtelehealth systems.Methodology: Twelve telehealth offerings were evaluated and models representing theinformation exchange routes were constructed. Questionnaires were used to validate thediagrammatical representations of the models with a response rate of 55%.Results: The models were classified as possessing four sections: preparing for data transfer,data transfer, information generation and information transfer from health professional topatient.In preparing for data transfer, basic data entry was automated in most systems thoughadditional inputs (i.e. information about diet, lifestyle and medication) could be enteredbefore the data was sent into the telehealth system. For the data transfer aspect, results andadditional inputs were sent to intermediate...

Abstract Objective: Proprietary intermediate telehealth devices are those which are specifically designed as connectors between the entities of telehealth systems. This article seeks to understand what are the capabilities of such devices and then to investigate how these are clustered on the current generation of devices. Materials and Methods: Fourteen current-generation devices available from 12 device providers were selected and analyzed. Four categories of questions were composed to evaluate the devices: setup/ configuration, available features, inputs, and outputs. Results: Data were collected and synthesized on the following capabilities: availability from suppliers, setup, environments of use, multiple-condition monitoring, multiuser capabilities, prompts, reminders and alerts, interaction with the health professional, access t...

Informatics related to point-of-care devices denotes the ability to translate stand-alone biological data into meaningful information that can be interpreted to enable and support users in taking the most appropriate steps to aid in managing their health. This paper considers small point-of-care devices used outside healthcare environments, and presents glucometers as an example. The paper seeks to evaluate the current level of servitization of point-of-care testing devices and considers whether they are, or could form, the product-core of a product-service system. The type of product-service system, its informatics requirements, and the services such a system could provide are also considered.
