he O'Malley administration launched an effort Thursday to bring medical services to disadvantaged neighborhoods by designating the state's first five "health enterprise zones" created under a law passed last year. One of the areas selected for such a zone, aimed at bringing health care to the poor, is in West Baltimore, where the Bon Secours Health System will take a lead role. Lt. Gov. Anthony G. Brown, who led the administration's efforts to start the four-year, $16 million pilot project, announced that the other four zones will be in Annapolis, Capitol Heights (Prince George's County), Greater Lexington Park (St. Mary's County) and Dorchester-Caroline counties.
