Research at COI

We are a multidisciplinary group of providers working on patient-centric care along the continuum.

Our team of clinicians and researchers work closely together on research initiatives to improve the utilization and effectiveness of healthcare delivery and develop new strategies to provide evidence-based quality care. We primarily focus on patient-reported outcomes, which capture the patient’s perspective of the impact of orthopedic-related care on quality of life and ability to function.
