Group Members • Butt, Salman • MOT Model: Domain/Goal Maps • LAG Strategies • Researching adaptation in healthcare • Fernando, Charith • MOT Model: Domain/Goal Maps • LAG Strategies • Researching adaptation in healthcare • Yang, Hui • Researching Healthcare information • Domain Model
Index • Motivation for the chosen topic • Related Research • Main Findings • Adaptive Information for Consumers • Demonstration • Further Research • Conclusions • Questions • References
Motivation • Internet has provided new opportunities for new generation of users, “the health information consumers”. • Can bring real benefits and have a big impact on the lives of consumers • Growing need for adaptive healthcare information.
Related Research • Adaptive user interfaces for health care applications, IBM [5] • Techniques of Adaptive Hypermedia [6] • Providing personalized accurate healthcare information [7]
Main Findings • Generic health information has a less impact than health information tailored to the individual • An increasing number of people are now using the Internet to support their healthcare. • The amount of information available on the web continues to grow. • Web based interventions to provide knowledge can have more impact than non web-based interventions
Health Education Goals • To Inform, to enable decision making or to persuade • Adapt to the needs of the patients both emotional and informational and adjust content accordingly. • To make sure the patients follow prescribed medical plan. • Educate patients on medications and its side effects.
What needs to be captured (User Modelling) • Medical condition and the state of the patient • Current treatments • Patient's current mental and emotional state • Different types of personality
How to Capture the Information • Existing patient records. • Standardized questionnaires: Personality, Stage of change, anxiety level • Psychological sensors: Emotional state and stress, Motivation levels.
User Modelling • State of change model - The model assumes that people progress through very distinct stages of change on their way to improve health • Pre-contemplation - people see no problem with their behaviour and don’t intend to change. • Contemplation – people understand the problem and its causes and start to take action. • Preparation – planning to take action and putting together a plan. • Action – in process of making changes • Maintenance – health behaviour continues on regular basis. • Termination – no problem or threat presented.
Techniques for Adaptation • Page Variant Approach – Different versions of each page. • Versions have to be written in advance • At runtime most appropriate page will be displayed. • Fragment-Variant approach – Constructed by combining appropriate set of fragments. • Fragments refers to a self contained information element eg. Text paragraph or picture • Page Constructed by selecting and combining an appropriate set of fragments.
Techniques for Adaptation Cont... • Natural Language Generation(NLG) • Natural Language Generation (NLG) is the natural language processing task of generating natural language from a machine representation system such as a knowledge base or a logical form. • It involves: • Content planning; deciding what content is most relevant to the current user. • Content Presentation; deciding how to most effectively adapt the presentation of the selected content to the user.
Evaluation • Usability of the overall system • Evaluate whether the content presented according to the system goals • Anxiety levels • Level of Compliance • State of Health • Validity of the content presented • How privacy is maintained when it comes to patient data
Evaluation Techniques • Questionnaires: Rate & Compare systems • Monitoring usage of the system (if permitted) • Randomized evaluation • Patients are randomly assigned and results monitored • Cannot always draw conclusions • Costly approach • Usually used to decide benefits of various treatments and monitor behavioral towards different systems (web vs. non-web or tailored vs. generic data)
Issues with Health Care Information • Privacy, security and trust. • Patient’s emotional state and attitude • Updating the user model
Demonstration of our system • Adaptive Healthcare Information system adapted in two main strategies • Monitor user behaviour to identify the medical condition of the user/patient • Enable the user to adapt the system to its medical condition and the state.
Adaptive Behavior • Show articles on different health conditions • Capture the user’s condition by this • Show educational articles and medication details according to the user’s identified condition • Let the user configure the system on medical condition and the state • Show medical condition related articles and the educational material according to the user’s preferences • Show medications according to the state of the health condition
Conclusions • We learned that • There is a growing interest in health care applications • The system not only educate patients but also assists health professionals • Promotes better communication between both health professionals and between patients and their health care team • Provides diagnostic tools and assists in health care provision
Further Research • How to capture patients emotional states • Measuring anxiety levels • Detecting the current mental state of the patient • Better communication between patients and health care professionals
