1 FUTURE OF HEALTHCARE USING WIRELESS MONITORS Masako Miyazaki, Associate Professor Faculty of Rehabilitation Medicine, University of Alberta Presented at the CMC Workshop in Ottawa February 5, 2010

2 What I see as key issues in Wearable Wireless Devices research Complexity of sensing technologies Multi stakeholders Multi purpose Cost Life span of technolgy

3 Sensors such as HR, ECG, BP, BG, PO2, PCO2, pedometer, weight, temperature, Respiration and etc. Communication device Sensing >local communication device such as cell Local communication device >data center Interpretation of data Data mining and clinical parameter pre determined by healthcare provider Clinical applications Diabetes, post surgical follow up, COPD, etc.

4 My research infrastructure needs related to the design, prototyping and testing of Wearable Wireless Devices It is not feasible to R & D Wearable Wireless Devices on campus resources alone. There are grant funding for R & D and clinical trials. Prototyping would require additional funding from the government. The prototype have to meet the regulatory compliance requirement before the clinical trials. No funding for commercialization.

5 If it is NOT wireless

6 Home Care Technology: The Concept 21 st Century Solution Bring round the clock health care to patient Home based healthcare service via sensor technologies, smart systems for home, and effective telecommunications Integrated continuum of care service for patient:

7 Why Home Care? Traditional hospital-base care service disables the patient Unfamiliar environment Isolated from social support structure Patients have to dependent on others

8 Home Health: Market Directions (USA) Large and growing market One of few markets in the medical industry show growth (~20% projected until 2025) 1990s: Average annual rate of growth ~20% 1996: 18% sales growth of medical device products for home care (market size $12-20 Billion) infusion therapy, diabetes, respiratory, cardiac, etc. Growth due to Aging Baby Boomer population Health care policy changes

9 Home Health: Current Conditions (USA) Current Market Size for Home Care Products: In US: $12 Billion (out of $55 B total for medical devices) Worldwide: $20 30 B (out of $130 B) Home Visits: ~ 550 million home visits/year 7 million $75 each visit (avg) Typical nurse can make 5 visits/day Not new concept Idea is to use technology to increase quality of care, efficiency of nurses, and reduce cost

10 Wireless Wearable Physiological monitor (WWPM) Core Participants

11 Pulse Sensor

12 Power charger

13 Wireless Station

14 System Overview Sample schedule Central server (CS) Time 10:00 Action Measure pulse Display Result pulse rate Schedule 12:00 Take medication Medicine yes or no 13:00 Eat lunch Lunch yes or no 14:00 Measure Glucose Glucose Glucose Value Internet 18:00 Take medication Medicine yes or no Data Schedule Home Internet Wireless Station (WS) Data Call Glucose monitor Clinician Features Bi-directional communication Integration of additional devices to WS Wearable pulse sensor (WPS)

15 WWPM system: The core system contains three components: the Central Server System (CSS) - a hardware and software solution; the Wireless Station (WS); and the Wearable Pulse Sensor (WPS). The CSS allows a care plan to be created for any individual that has a WS and a WPS. The CSS also has programs for storing, interpreting and visualizing physiological and client response data.

16 Phase I WWPM System Pilot Study (Volunteer and Home Care Clients) The primary purpose of this pilot study was to determine the acceptability (e.g., user friendliness, convenience, etc.) of the WWPM system in a sample of healthy adult Volunteers and Home Care Clients within the Capital Health region in Alberta. The pilot study was a prospective study using structured interviews as the primary data collection technique.

17 Phase II: Clinical trial with home care clients in Alberta Health Service Capital Health The purpose of this study was to examine the function of the WWPM System for exchanging messages between home care clients and health professionals, and for remote monitoring of pulse and blood glucose levels. Community residing healthy older adults while performing an activity of daily living.

18 Results We have shown that it is possible to integrate clinical home care and wireless networking as a new way of collecting physiological data. Unobtrusive, wearable sensors will certainly allow us to collect large volume of data, and mine the data for new information over time. We may find significant individual differences in how patients' bodies respond to medications, to medical treatment, to the emotions of others, to food they eat, and to their environment.
