Emergency room nurses in Richmond, Va., are helping to reduce the number of nonemergency ER visits by answering 911 calls for minor health care problems -- such as an ear infection or fever. The 750 people who have been helped by the nurses -- rather than going to the ER -- have saved the nonprofit Richmond Ambulance Authority more than $266,250, which more than covers the salaries of the four part-time nurses who answer the calls.
