Center of Excellence


Apply Online

The Center of Excellence in Bariatric & Metabolic Surgery program is an OSSI initiative aimed at Indian national patient safety and quality improvement available to all bariatric surgeons and facilities across the nation. The COEBMS program reflects the specific needs of obese patients and the unique roles and responsibilities of bariatric and metabolic surgery providers. The COE needs to be renewed every three years

Safe patient care is the result of both the individual surgeon and the facility where the surgery is performed. The COEBMS certification is therefore awarded to a facility and its associated surgeons who have successfully completed the designation process, which enables patients to distinguish providers who have met the state-of-the-art requirements with regards to volume, manpower and facility for delivering high-quality perioperative and long-term follow-up care.

Benefits :

  • Ensure patient safety
  • Improve the quality of the services offered by both Institutions and Surgeons
  • Ensure highly efficient and safe patient treatment
  • Advise existing bariatric institutions to upgrade their status to level of excellence
  • A Registry that will guide our decisions and respond to challenges by our colleagues, insurance carriers, health care providers, governments and the public.
  • An invaluable resource for research.
