Clinical Outcomes Research Unit (COR Unit)

The Clinical Outcomes Research Unit (COR Unit) focuses on using patient-based and quality of life outcomes to improve clinical care. Under the direction of Richard Gliklich, M.D.,the COR Unit has developed a series of patient-based measures used internationally for clinical trials, registries and quality improvement programs. Some of these validated measures include:

• Chronic Sinusitis Survey (CSS, also called Nasal Health Survey)
• Snore Outcomes Survey (SOS) (Click to see survey and automated scoring algorithm.)
• Voice Outcomes Survey (VOS-5)
• Head and Neck Survey (HNS)
• Chronic Ear Survey (CES)
