Key Terms

clinical informatics technical

Clinical informatics organizes and analyzes medical and patient data using software, databases and tools so clinicians can make faster, safer decisions—think of it as a traffic-control system and smart filing cabinet for healthcare information. Investors care because these systems drive adoption of digital tools, reduce errors and costs, help providers meet regulatory requirements, and create recurring revenue opportunities for companies that sell or host the technology.

electronic health records technical

Electronic health records are digital versions of a patient’s medical history, tests, treatments and prescriptions that healthcare providers create and store electronically instead of on paper. For investors, they matter because they drive recurring software and services revenue, enable new data-based products like remote care and analytics, and carry financial risk from privacy rules, data breaches and the ease of sharing records between systems—factors that affect a healthcare or technology company's value.

graduate medical education medical

Postgraduate clinical training for physicians, commonly called residency and fellowship, where medical school graduates practice under supervision to gain the skills and board certification needed to work independently. It matters to investors because GME shapes the supply and specialization of doctors, influences hospital and university staffing costs and revenues, and is tied to government funding, accreditation rules and workforce trends that can affect healthcare providers, insurers and medical education-related businesses—like an apprenticeship that determines future labor supply and institutional expenses.

NASHVILLE, Tenn.--(BUSINESS WIRE)-- HCA Healthcare, Inc. (NYSE:HCA) today announced that Michael Schlosser, M.D., MBA, senior vice president and chief transformation officer, has been appointed executive vice president and chief clinical officer, effective Sept. 1, 2026.

Also, effective Sept. 1, Charles Gressle, president of HCA Healthcare’s East Florida Division, has been appointed president of HCA Healthcare’s new Ambulatory Operations Group.

Dr. Schlosser will succeed Dr. Michael Cuffe, who announced in June that he will step down as executive vice president and chief clinical officer, effective Aug. 31.

In his new role, Dr. Schlosser will report to Sam Hazen, chief executive officer of HCA Healthcare, and assume responsibility for the company’s Clinical Services Group, which includes Quality, hospital Chief Medical Officers, Nursing, Graduate Medical Education, Hospital Based Services and other enterprise clinical functions. He will continue to lead HCA Healthcare’s Digital Transformation and Innovation organization and oversee the company’s clinical informatics organization and enterprise strategy for electronic health records, digital technologies and data platforms.

“Mike is a trusted physician leader whose experience and commitment to our mission have strengthened our organization,” said Hazen. “He has played an important role in advancing our clinical and digital capabilities, and his expanded responsibilities will extend the impact of that work more fully across HCA Healthcare as we continue integrating innovation, AI technology solutions and clinical excellence to improve care for our patients.”

Before assuming his current role, Dr. Schlosser served as group chief medical officer for HCA Healthcare’s National Group and vice president of clinical excellence and surgical services for the Clinical Services Group. Earlier in his career, he served as chief medical officer for HealthTrust and chief of staff at TriStar Centennial Medical Center.

Dr. Cuffe will continue to serve HCA Healthcare as an executive consultant through February 2027 to support the leadership transition.

“We are grateful for Mike Cuffe’s many contributions to HCA Healthcare and the lasting impact he has had on our organization,” said Hazen. “His leadership has strengthened our clinical enterprise and improved care for the patients and communities we serve. We appreciate his continued support during this transition and wish him all the best.”

As president of the Ambulatory Operations Group, Gressle will report to Jon Foster, executive vice president and chief operating officer. Gressle will be responsible for HCA Healthcare’s Physician Services Group, which includes Urgent Care operations and Physician Practice Operations. In addition, Gressle will oversee HCA Healthcare’s Surgery Ventures Group and other corporate service line and support functions. The group, which includes more than 2,700 facilities and clinics, is designed to strengthen integration across the company’s growing ambulatory network and enhance coordination in support of patients, physicians and caregivers.

“Charles is a proven leader with deep operational experience and a strong track record of building high-performing teams,” said Hazen. “As we build out our networks to meet the growing demand for our services, this new structure allows for better network integration with more service line focus, and most importantly, it makes it easier for our patients to navigate our systems.”

Searches for successors to Dr. Schlosser’s and Gressle’s current roles are underway.
