Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

"Wash your hands." Variations on those three simple words adorn many washrooms and hospital corridors because handwashing can help prevent the spread of disease.
It's not a new idea: Dr. Ignaz Semmelweis first proposed having doctors wash their hands before treating patients in 1847.
Although washing hands may be a simple and effective way to reduce the spread of infection, getting care providers to consistently wash their hands when entering patient rooms and coming into contact with patients may be more challenging. A similar challenge was observed by Dr. Semmelweis himself.
At Toronto Rehab, every patient room has easy access to soap and water or an alcohol-based hand sanitizer. When sensors were added to the soap and sanitizer dispensers, opportunities for improved hand hygiene to reduce the spread of infection were discovered.
To help encourage handwashing, a research team led by Senior Scientist Dr. Geoff Fernie invented a wearable badge that provides a discrete reminder in the form of a vibration and gentle beep. With sensors that are easily installed, the badges can determine when a staff member enters or exits a patient room, and whether they have dispensed soap or sanitizer.
If they forget to clean their hands, the badge gently vibrates to discretely remind them. After washing, a light on the badge glows green for positive encouragement.
The team recently completed a study to measure the effects on handwashing behaviour and to determine whether long-term use of the system could lead to sustained increased hand washing when entering patient rooms and delivering patient care.
The results were very promising: soap and sanitizer use nearly doubled when the hand hygiene prompting badges with the reminder were introduced at several Toronto Rehab clinical units.
The improved performance was sustained over the course of a year, demonstrating the effectiveness of the technology.
"Our findings show that this technology holds great promise for ensuring proper hand hygiene," says Dr. Fernie. "It may one day be integrated into hospitals around the world as an important part of the global commitment to caring safely."
