The only hospital serving the Upper Keys community, Mariners Hospital is a 25-bed critical access hospital located in Tavernier and founded in 1962. In addition to medical-surgical and intensive care units, Mariners is home to the southernmost branch of Baptist Health's Miami Cancer Institute. Specialized nurses, trained by the Oncology Nursing Society in chemotherapy/biotherapy administration and pain management, offer care in a supportive and healing environment. Mariners also operates the only hospital-based hyperbaric chamber in the Keys, which uses oxygen therapy to treat many illnesses and injuries, including diving-related decompression sickness, non-healing wounds, radiation tissue damage, and carbon monoxide poisoning. The Diabetes Care Center and Sleep Diagnostic Center are also located on the campus, as well as swing bed services, which are available to patients who are recovering from illness or injury and require specialized care. And to help the Keys community achieve a new level of wellbeing, the 7,000-square-foot Wellness Center, offers a comprehensive line of gym equipment, exercise physiologists, group exercise classes, and personal training.
