NASHVILLE, Tenn. — Dr. Sammie Stewart Mosier, the Senior Vice President and Chief Nurse Executive of HCA Healthcare, passed away suddenly this week, shocking colleagues, nurses and healthcare communities across the country. Her death has sparked an outpouring of grief and appreciation for a leader whose influence reached into hundreds of hospitals and tens of thousands of caregiving professionals.
Dr. Mosier wasn’t just a high-ranking executive at one of America’s largest healthcare systems — she was the heart of its nursing mission. At HCA, where more than 100,000 nurses depend on coordinated leadership and advocacy, she helped shape strategies that improved clinical practice, deepened professional development, and strengthened the support nurses receive every day.
Her journey began decades ago on the hospital floor as a registered nurse, a role that grounded her leadership style in real, everyday patient care. From those early days at Frankfort Regional Medical Center to the helm of an enterprise-wide nursing agenda, Dr. Mosier’s rise was defined by her commitment to compassion, mentorship, and excellence in practice.
Professionally, she was known for her visionary approach to nursing leadership. Under her guidance, HCA expanded its clinical education platforms, strengthened mentorship programs, and championed nurse advocacy at every level — from new graduates finding their footing to veteran leaders shaping policy. Many within the profession credit her with helping launch initiatives that made a meaningful difference in career development and patient care outcomes.
But beyond her professional achievements, it was her personal warmth and genuine care that left an enduring mark on colleagues and friends. Nurses who worked with her remember a leader who listened, encouraged, and brought out the best in others — someone whose laughter and support could turn a challenging day into a moment of resilience. A fellow nurse leader recently shared heartfelt memories of Dr. Mosier’s mentorship, emphasizing how deeply she connected with people both personally and professionally.
The reaction since the news of her passing has been profound. Tributes from across the healthcare field speak not only to her influence but to her humanity — the way she lifted others up, fought for their recognition, and reminded everyone of the human side of caregiving. Her legacy isn’t just policy or programmatic; it’s in the countless nurses who feel honored to have learned from her example.
Details about memorial services, obituary arrangements, and tributes from HCA Healthcare are still emerging. For now, families, colleagues, and friends are holding space for loss while also celebrating a life that reshaped nursing leadership and touched so many hearts.
