    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."

    Informatics for devices within telehealth systems for monitoring chronic diseases
    (Cranfield University, 2011-04) Adeogun, Oluseun; Alcock, Jeffrey R.; Tiwari, Ashutosh
    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 perspective. (iv) to identify the capabilities of telehealth systems. (v) to evaluate key components of telehealth systems (i.e. POC devices and intermediate devices). (vi) to analyse the capabilities of telehealth systems as enablers to a healthcare policy. The literature review showed that data transfer from devices is an important part of generating information. The implication of this is that future designs of devices should have efficient ways of transferring data to minimise the errors that may be introduced through manual data entry/transfer. The full impact of a servitized model for point-of-care devices is possible within a telehealth system, since capabilities of interpreting data for the patient will be offered as a service (c.f. NHS Direct). This research helped to deduce components of telehealth systems which are important in supporting informatics and decision making for actors of the system. These included actors and devices. Telehealth systems also help facilitate the exchange of data to help decision making to be faster for all actors concerned. This research has shown that a large number of capability categories existed for the patients and health professionals. There were no capabilities related to the caregiver that had a direct impact on the patient and health professional. This was not surprising since the numbers of caregivers in current telehealth systems was low. Two types of intermediate devices were identified in telehealth systems: generic and proprietary. Patients and caregivers used both types, while health professionals only used generic devices. However, there was a higher incidence of proprietary devices used by patients. Proprietary devices possess features to support patients better thus promoting their independence in managing their chronic condition. This research developed a six-step methodology for working from government objectives to appropriate telehealth capability categories. This helped to determine objectives for which a telehealth system is suitable.

    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.

    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.
