SAFETY HARBOR — Mease Countryside Hospital is launching a $156 million expansion to build a four-story patient tower with all private rooms and a four-story parking garage.The tower will include 70 private patient rooms, a 30-bed observation unit, critical care services combined in one cohesive unit, aligned outpatient and inpatient surgical services, expanded women’s care, new outpatient chemotherapy services and a new endoscopy unit.When the tower is completed by the target date of August 2020, the portion of private rooms at the 311-bed facility will increase from 31 percent to 82 percent, according to a news release. The 950-space parking garage, expected to be built by October, will also serve to enhance access, according to hospital president Lou Galdieri.An elevated pedestrian walkway will connect the new tower to the hospital, taking people over Mease Drive. Landscaping will aim to enhance greenspaces and discourage pedestrian traffic on the street level.The hospital, on McMullen-Booth Road in Safety Harbor, has been awarded 12 Top 100 Hospital designations in the areas of stroke, orthopedic, intensive care and overall care by the Truven Health Analytics 100 Top Hospitals: National Benchmarks for Success. It is part of the BayCare Health System."We are responding to the growing needs of our surrounding community by enhancing access and efficiency, which we believe will improve the experience of our patients and their families," Galdieri said.
