Item Open Access Capabilities of proprietary intermediate telehealth devices(2011-10-28T00:00:00Z) Adeogun, Oluseun; Tiwari, Ashutosh; Alcock, Jeffrey R.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 to historical data, device inputs, and their transfer technology. Conclusions: There are three main roles for proprietary intermediate devices in telehealth systems: displaying information to the patient; receiving data manually/automatically; forwarding results and questionnaire responses to another entity. Provider Perspective: Intermediate devices are usually part of closed proprietary systems. Providers produce disease-customisable devices. Connectivity is considerably ahead of the current generation of point-of-care devices. However, little data are available on connection to rest of the proprietary system. Patient Perspective: It shows clear benefit that one intermediate device can be potentially used with several chronic conditions. Simple setup, authentication procedures, and automatic data transfer are key design aspects. Health Professional Perspective: Little direct interaction with the health professional was observed. Payer Perspective: Details of costs of devices are generally unavailable; system providers indicate that cost variability is based on "user requirements."Item Open Access Informatics-based product-service systems for point-of-care devices(Elsevier, 2010-12-31T00:00:00Z) Adeogun, Oluseun; Tiwari, Ashutosh; Alcock, Jeffrey R.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.Item Open Access Models of information exchange for UK telehealth systems(Elsevier Science B.V., Amsterdam., 2011-05-01T00:00:00Z) Adeogun, Oluseun; Tiwari, Ashutosh; Alcock, Jeffrey R.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 devices, which were connectors between pointof-care devices, patients and health professionals. Data were then forwarded to either a webportal, a remote database or a monitoring/call centre. Information generation was eitherthrough computational methods or through the expertise of health professionals. Informationtransfer to the patient occurred in four forms: email, telehealth monitor message, textmessage or phone call.Conclusion: On comparing the models, three generic models were outlined. Five differentforms of information exchange between users of the system were identified: patientpush,system-stimulation, dialogue, health professional-pull and observation. Patient-pushand health professional-pull are the dominant themes from the telehealth offeringsevaluated.
