Physicians who choose to partner with DaVita have direct access to some of the world's leading clinical experts in our discipline. Together, DaVita's entire clinical team, including the Office of the Chief Medical Officer (OCMO), the Physician Council, group medical directors and our physician partners, identify, shape and drive the patient programs that are implemented in our more than 2,000 dialysis centers. When determining our approach to care at DaVita our clinical leadership team continuously innovates new and better ways to address patients' kidney care issues, as well as their comorbid conditions.
We listen to our physician partners because they know better than anyone what is best for their patients. We communicate with them multiple times a month via emails, e-newsletters, OCMO webinars and conference calls, and through NephLink.com, the leading online physician community for kidney care. In addition, by holding in-person meetings, such as our Physician Council meetings and our annual Physician Leadership Meeting, we make sure that our physician partners have access to their peers in order to discuss important issues that arise in daily practice. And in turn, we invite physicians to advise us on our policies and protocols as they are developed.
DaVita established OCMO to ensure that a group of experienced nephrologists is dedicated to working with the business leadership at DaVita to provide value for patients, deliver high quality outcomes and be responsible stewards of resources. OCMO is committed to focusing on the needs of DaVita's medical directors and nephrologists by strengthening the clinical-operational partnership and developing new tools and resources to help tackle the daily challenges in kidney care. OCMO is led by:
