Doctors in emergency rooms around the world are using clinical decision rules developed at The Ottawa Hospital to figure out if diagnostic tests are needed for particular problems. The rules save time and money and spare patients from unneeded and often uncomfortable diagnostic procedures. Examples include:
- The Ottawa Ankle Rules, used to figure out if an injured ankle needs an x-ray
- The Wells Rule, used to figure out a person’s probability of having a deep-vein blood clot
- The Canadian C-Spine Rule, used to figure out if a person with neck injuries needs a CT scan
Researchers from Harvard named these three rules among the top five of their kind in the world. They’ve even been used on TV shows such as ER and Grey’s Anatomy.
