Physicians treating refugees and immigrant populations face a minefield of potential cultural gaffes. They should not touch a Muslim man during the initial interview. A nod of the head may mean "no" instead of "yes" if the patient is Albanian. Among Latinos, the head of the family, not the patient, makes treatment decisions. A $604,000 federal grant from the National Heart Lung and Blood Institute to the University at Buffalo will help new and experienced physicians avoid such missteps.
