Problem:• Growth in chronic diseases and conditions, e.g., obesity, type 2
diabetes, and aging population
• Resulting lower quality of life and higher healthcare costs
“Individuals’ daily decisions and health behaviors are the most critical factor in how they fare”
Solutions: mHealth technologies are now available to help
• Mobile Devices (Smartphones)─ “The Future of Medicine is in your Smartphone”, Topol, WSJ, Jan 9, 2015.
─ “Pocket Doctor”, Strong, Agu, Pedersen, Tulu, Practical Patient Care, Oct 2012.
• Wearable, wireless health sensors and devices
• Online health information (e.g., web sites, patient portals)
• Online health communities (e.g., disease-specific support groups)
Why mHealth Technologies?

Key Design Challenges formHealth Solutions
3
Discontinued use before benefits occur• Within months, many mHealth apps are no longer used
• Many mHealth apps provide little or no user feedback, leading to discontinued use
• Effort burden (e.g., manual data entry) key in discontinued use
• Smart systems and automation can reduce burden but also reduce user control, which promotes engagement and use
mHealth devices are often viewed as data collection devices, rather than patient engagement devices
Lack of behavior change• Double adoption problem: Must adopt the app or device and adopt
new behaviors, both over the long-term
• Supporting healthy behaviors differs from supporting task completion, and requires voluntary usage assumption

Use mHealth technologies to design, develop and test apps that
• Engage patients in managing their health
• Motivate patients to adopt healthy behaviors
• Support self-management of chronic conditions, and wellness
Conduct research that
• Seeks to understand and generate predictions from collected health and usage data (e.g., using data mining and machine learning)
• Tests ideas, techniques, and predictive algorithms
Employ best clinical and technological practices in
• Disease management, Behavioral medicine, Wellness
• User engagement, Designing the user experience
Focus has been on
• Smartphone apps – design, develop, and test
• Patient portals – how and why patients use them

• TJR-Decision─ Physician-patient decision
making about Total Joint
Replacement, based on pain
and activity data
─ AHRQ funding
─ http://tjrapp.wpi.edu
• Sugar─ Advanced type 2 diabetes
and diabetic foot ulcers (image processing)
─ NSF funding─ http://sugar.wpi.edu
WPI’s Health Apps (sample)
For chronic disease, primarily elderly

• Relax─ Stress-induced eating
─ NIH funding
• SlipBuddy─ Overeating episodes
─ NSF REU Site funding
8
• Habit─ Weight loss─ NIH funding─ http://habit.wpi.edu/
• Mom-o-meter─ Control gestational
weight gain
WPI’s Health Apps (sample)
For weight control

• Socialoscope─ Senses loneliness by
analyzing smartphone activities of college students
─ At risk freshmen, seniors, internationals
WPI’s Health Apps (sample)
For college student health
• SleepHealth─ College student
sleep health• Alcogait
─ Senses intoxication levels from gait
─ Put smartphone in your pocket and it tracks as you walk
Designing to Meet mHealthChallenges
• Minimize manual data entry
• Predict discontinued use and intervene
• Support goal setting and other behavioral medicine principles
• Follow user experience and behavior change support system design principles

Design for Minimal Manual Data Entry
11
SleepHealth will learn from data and reduce data entry over time
SlipBuddy only collects data on
problem episodes
Sugar uses Bluetooth glucometer and scale; footbox
for wound image capture

Predict and Intervene to Avoid Discontinued Use
12
Sugar provides feedback on measure-ment frequency and activity levels (e.g., goal of measuring weight once a week)
Sugar provides a summary of usage activity to care team, for purposes of human interventions
Socialoscope captures measures of smartphone usage to predict loneliness
SleepHealth will continually monitor usage and predict when usage is declining
Worcester Polytechnic Institute
Healthcare Delivery Institute
13
For Sugar, users can set glucose, weight, and activity goals, and Sugar’s feedback is relative to those goals
Support Goal Setting, Other Behavioral Medicine Principles
HABIT’s design is based on behavioral medicine principles that are highly effective for weight management
Worcester Polytechnic Institute
Healthcare Delivery Institute
Follow User Experience and BCSS Design Principles
14
Design Principles
• Delight the user with an excellent user experience
• Generate smart feedback and context-appropriate interventions─ Based on prior user input, time, location
─ SleepHealth will suggest different interventions depending on point in the educational cycle (e.g., near end of term) and location of the user
• Use Behavioral Change Support Systems (BCSS) design recommendations─ Use system features (e.g., personalization)
that aid behavioral change
─ Use system features that are persuasive and motivating
Allow some app personalization
For Mom-o-meter, provide pink, blue backgrounds; Display baby names
Worcester Polytechnic Institute
Healthcare Delivery Institute Conclusions and Next Steps
15
Lessons Learned
• Design for patient engagement – to attain continued use and behavior changes
• Development team needs technical, clinical, and behavioral expertise; also patient involvement
Next Steps
• Smarter feedback
• Design and test interventions
• Add more group and community level features
