SAN ANTONIO – Micro-hospitals are built in areas where there’s a need but not a big enough demand for a traditional hospital. Baptist Health System is opening a micro-hospital called Baptist Emergency Hospital near Cupples Road and Highway 90. Micro-hospitals are good for minor emergencies, like if someone breaks a leg or if someone thinks they are having a heart attack. Stone said micro-hospitals are cheaper than full-service hospitals because they’re not as large, and they aren’t set up to treat everything. The Baptist Health System micro-hospital will open by the end of the month.
