Immigrants make mark in Massachusetts healthcare work force

Immigrants now make up more than a quarter of the workforce in several key healthcare jobs in Massachusetts, such as pharmacists, medical scientists, and surgeons, according to an executive summary for a study by professors from the University of Massachusetts at Boston, Tufts University, and the University of California, Berkeley. But the study's authors say the state should find more ways to move immigrants into the healthcare field to meet a growing demand for care, fueled partly by Massachusetts' campaign to make sure almost every resident has health insurance.
