Many of the health care technology solutions available today are designed to help physicians or professionals in health care institutions. Taking a significantly different approach, the Project HealthDesign team based at the University of Rochester wants to use technology to help people diagnosed with congestive heart failure (CHF) manage their health from their homes, as part of their daily lives. Building on decades of research on how people interact with technology to solve problems, the Rochester team chose to develop a personal health management assistant that helps patients better understand and interpret the symptoms they experience. The team focused on this disease not only because millions of Americans suffer from CHF but because the condition requires, as with many chronic illnesses, that the patient monitor themselves for changes and follow specific guidelines for self-care activities to keep themselves stable and out of the hospital.
Through focus groups, interviews and surveys, the Rochester team created designs for a relevant personal health record (PHR) application. They found that the most common questions the heart failure patients have include: "How am I doing today?" and "What can I do to help myself?" While they found that patients were willing to "check in" daily with a computerized device, they also found that patients wanted to spend fewer than five minutes per day using it. Building on the team’s previous experience in demonstrating the inherent power of the spoken word in capturing information, the team designed a computerized "conversational assistant" to provide a "daily check-up" for CHF patients.
Through a series of questions and responses, written in conversational language, patients respond with their own appraisal of how they are feeling. The computer decodes the person’s own words and then interprets how they are doing each day. Then the person receives personalized treatment recommendations based on established guidelines for heart failure patients, and the system collects longitudinal data to share with patients and their doctors.
The Rochester team now has a simple prototype system for chronic heart failure self-care management and has evaluated it informally. Interaction is via spoken language or typed text chat (written in standard non text-messaging language). Through computer-generated graphics, the system’s displays its understanding of the patient’s own words.
The team hopes to demonstrate that this device will not only keep patients out of the hospital setting by alerting them to potential changes in their disease but also give patients confidence in their ability to go about living regular lives.
