The Jefferson Health hospital in North Philadelphia was cited by inspectors for providing incorrect mammogram results. "We are pleased to report," the letter from Jefferson Einstein Philadelphia Hospital read, "that the result of your recent mammogram shows no sign of breast cancer." But the letter was wrong. Her scan had actually been inconclusive, and an internal error resulted in the patient not being notified to come back for additional testing. The issue came to light one year later, when the patient returned for another routine mammogram and was diagnosed with breast cancer. The incident, described in a report released by Pennsylvania hospital inspectors in September, drew one of the state's harshest warnings for the North Philadelphia hospital formerly known as Einstein Medical Center.
