Short-Term Scientific Mission Msury Mahunnah Tallinn University of Technology Ehitajate tee 5, 19086, Tallinn msury.mahunnah@ttu.ee http://maurus.ttu.ee/sts/ 1. Details Beneficiary: Msury Mahunnah, Tallinn University of Technology, Estonia Host: Prof. Michael Schumacher, University of Applied Science Western Switzerland, Sierre Period: from 15th May, 2012 to 15th June, 2012 Place: 3960 Sierre, Switzerland 2. Purpose of the visit The purpose of the visit was to study and analyze possible architectural patterns for Personal Health Systems (PHS) at the Institute of Business Information Systems in the University of Applied Science Western Switzerland (HES-SO). The outcome of the visit expected to assist the STSM applicant to propose a methodology for developing such systems after comparing with other similar projects. 3. Description of the work As PHS is a new research era, there is no systematic approach to deciding its architectures. In proposing a methodology for developing PHS, we are particularly interested in the distributed architectures of a kind where stakeholders, such as patients and healthcare professionals, are presented by software agents that perform on behalf of their principles activities delegated to them [1]. The STSM at HES-SO helped the applicant to comprehensively study and analyze the actual architectural designs of the following two main projects related to patients with diabetes mellitus; (a) Ongoing project for providing continuous monitoring, diagnosis and treatment adjustment of Gestational Diabetes Mellitus (GDM) (b) Recently started project for providing COntinuous Multi-parametric and Multi-layered analysis Of DIabetes TYpe 1 and 2 (COMMODITY 12 Project) With the assistance from the research group members at the host university, the STSM applicant explored the following matters related to the project (a) mentioned above; - Comprehensively studied and analyzed a normal 3 tier client-server architecture where presentation layer contains a web interface for caregivers as well as a mobile interface for patients to send their observations and receive notifications from the system. The application layer contains a well designed multi-agent platform GOLEM [2] attached to it for the purpose of performing detailed processing of the collected observation(s). GOLEM implements the agent environment concept and it is built around four main entities: agents, avatars, objects, and containers. - Was exposed to interoperability issues experienced by group members when deploying project (a) at Lausanne Hospital in Switzerland. Three main types of interoperability have - - been identified: technical interoperability, syntactic interoperability, and semantic interoperability. Went through programming concepts and testing phase of the whole system including web interface for caregivers, mobile application for patients, and the application layer including agents in GOLEM as well as the database for storing information on continuous monitoring, diagnosis, and treatment of patients with GDM. Learnt on the actual challenges experienced by the project members especially when communicating with other healthcare stakeholders such as caregivers and hospital administrators about the suggested approaches for improving the healthcare delivered to diabetic patients. 4. Future work It is categorized into two parts: - The recently started project (b) is anticipated to be more complex as it involves issues of personalizing a given treatment according to physiological values, lab test results, diet, physical examinations, genetic data and contextual data about the patient with diabetes mellitus type 1 and 2. We have started working on simplifying the analysis and design models for project in (b) by using a methodology appropriate for designing complex sociotechnical systems [3] proposed in the monograph co-authored by the applicant’s supervisor at the home university. The methodology is centered on the notion of “agent” that is used as a modeling abstraction rather than just a technological building block. - Using the lessons learnt at the Institute of Business Information Systems in HES-SO to compare with other similar projects for the purpose of proposing a methodology for developing PHS.
