Marshall recognized on Forbes Top Hospitals 2026. Posted On: April 13, 2026 PLACERVILLE, CA (April 13, 2026) - Forbes, the iconic business magazine and global media giant, has recognized Marshall on its Top Hospitals 2026 list. This prestigious listing focuses on healthcare quality measures that assess patient outcomes, hospital best practices, value, and patient experience. Recognition on the list reflects work taking place across Marshall's organization. According to Forbes, this inaugural listing of general acute care hospitals in the United States was designed to offer consumers unbiased information on which hospitals offer top-notch, high value medical services, and a benchmark against which hospitals can compare their performance to that of their peers. "What makes this recognition so gratifying," says Siri Nelson, Marshall's President and CEO, "is that the criteria looked at everything from our emergency, surgical, and stroke care, for example, to the work of our environmental services and hospital discharge teams. It is truly a recognition of the extraordinary work of our organization as a whole." To develop its ranking, Forbes analyzed data from the Centers for Medicare and Medicaid Services (CMS) Provider Data Catalog (PDC). Detailed evaluation criteria were chosen specifically because they have been developed and regularly tested by leaders in the healthcare community to meet rigorous national standards. Approximately 5,400 general acute hospitals were eligible for consideration. Of that initial pool, just under half met the inclusion criteria. Across the United States, only1,298 facilities received a rating of three stars and above.
Marshall Medical Center receives 2026 Women's Choice award(r) as one of America's best hospitals for ER wait time & efficiency. Health system Monday, March 2, 2026 LEWISBURG, Tenn. - Marshall Medical Center has been named one of the Best Hospitals for Emergency Timeliness by the Women's Choice Award, America's trusted referral source for the best in health care. This recognition places Marshall Medical Center in the top 4% of 4,655 U.S. hospitals offering emergency care services. "This recognition is a reflection of the multidisciplinary teams, including physicians, nurses, specialists and technicians who work together to provide quality care for our patients," said Maury Regional Health CEO of Rural Hospitals Phyllis Brown. "This award validates our commitment to maintaining strong systems and processes that enable our ER to operate efficiently, especially when time is of the essence in an emergency." Emergency departments play a critical role in the health care system, delivering life-saving care when every second counts. Unlike other hospital settings, ER teams often have only one brief encounter with patients - typically during moments of high stress and urgency - making timeliness, efficiency and patient experience essential. "Emergency departments can be incredibly stressful - especially for the elderly or a parent with a sick or injured child," said Delia Passi, founder and CEO of the Women's Choice Award. "In those critical moments, time becomes more precious than gold. The ER is a place where every second matters, and swift, informed decisions can save lives. That's why we honor hospitals that not only deliver care quickly but also earn high patient recommendation scores - demonstrating their commitment to both efficiency and compassion when it matters most." The Best Hospitals for ER Wait Time & Efficiency designation recognizes hospitals that excel in emergency timeliness while also providing outstanding patient experience. Rankings are based on the following performance measures reported by the Centers for Medicare and Medicaid Services (CMS): * Average time patients spend in the Emergency Department before leaving the hospital * Percentage of patients who left the Emergency Department without being seen * Admissions decision time to ED Department for admitted patients * HCAHPS recommendation rating To qualify, hospitals must meet or exceed the national average recommendation rating of 68%, ensuring that timely care is also delivered with compassion and quality. Hospitals that did not report or pass the third metric were required to rank in the top 25% for average ER time to remain eligible. Hospitals meeting these criteria and maintaining a 68%+ recommendation rating were ranked in the top 10% nationally, earning the Women's Choice Award for ER Wait Time & Efficiency. "Marshall Medical Center not only has some of the shortest ER wait times, but it also has a higher-than-average recommendation rating - an important factor for women making healthcare decisions," added Passi. Marshall Medical Center is one of 463 award recipients recognized for meeting the highest standards for emergency timeliness in the U.S. The 25-bed critical access hospital in Lewisburg serves residents of Marshall County and the surrounding area.
