Mayor Bill de Blasio is expected to announce today that the city has begun work on six new community health centers, part of a larger push by the administration to reduce health inequalities in certain neighborhoods. The mayor's plan, which he will unveil in his State of the City address, is consistent with the broader public health strategy being implemented by city health commissioner Dr. Mary Bassett, who is refreshing a 90-year old idea in an effort to improve health outcomes in some of New York's most challenged neighborhoods.
