Apple Patch Assisted Living Community to Use ALRT Constant Health Companion(TM) (CHC(TM)) System in All Their Homes

WINSTON-SALEM, NC--(Marketwire - December 4, 2007) - ALR Technologies, Inc. (OTCBB: ALRT) announces that Apple Patch Inc., an assisted living organization based in Crestwood, KY, is buying CHCs for each of the homes in their assisted living community. Apple Patch provides leading edge innovations in assisted living care for those with mental disabilities.

The CHC is a portable and easy-to-use adherence monitoring system. It addresses treatment non-adherence of patients with chronic illnesses by enhancing efficiency of healthcare providers and facilitates timely intervention. An innovative feature of the system is a documented audit trail to evaluate provider programs. Non-adherence of treatments currently contributes to over $150 billion a year of preventable excess healthcare costs. ALRT's CHC system provides the only comprehensive and affordable solution to this $150 billion a year problem.

Chris Stevenson, the executive director of Apple Patch, reports that his organization began using ALRT home compliance systems over a year ago and now with availability of the newly enhanced system, Apple Patch will be placing a CHC in each home. "Our caregivers have been asking about placing these systems for all our homes. The ALRT compliance system has provided our caregivers with the assistance needed to remember to complete or administer the many activities and medications that are essential for quality care. Now with the additional ability to monitor and document activities we will be able to provide more accurate and timely care as well as better understand when adjustments and education activities should be implemented.

"Bottom-line, the CHC system will result in better quality of life for the individuals we serve, bring better efficiency to our caregivers and lower our cost of care," adds Stevenson.
