As if a visit to the doctor is not stressful enough, many Marylanders have trouble understanding the doctor or making the doctor understand them. That’s where medical interpreters come in, and the need for interpretation has grown along with the region’s non-English speaking population. In the Johns Hopkins Hospital system, for example, there were 17,313 requests for an interpreter in fiscal year 2009. Four years later, requests had jumped to 40,424. And those numbers exclude Spanish requests at Bayview and Howard County General Hospitals, which are part of the Johns Hopkins system. Those hospitals run their own Spanish interpretation programs.
