THE BRONX - A popular medical center in the Bronx is scoring low when it comes to the safety of its patients. 

Three of Montefiore Medical Center's campuses, the Wakefield, Moses and Einstein campuses, have received "C" grades. The grades are assigned twice a year, and each campus has been given a "C" since the fall of 2013. 

Officials say the hospital safety score is becoming the gold standard for rating patient safety and is assigned to more than 2,500 hospitals across the nation. More specifically, it looks at how hospitals and other health care organizations protect their patients from errors, injuries, accidents and infections. 

However, not all Bronx-area hospitals received poor grades. Both Lincoln Medical Center and Bronx Lebanon Hospital received an "A," while Jacobi Medical Center and Saint Barnabas Hospital were given a "B."
