4 Massachusetts hospitals investigating: Patients’ files left at public dump

The unshredded records included pathology reports with patients’ names, addresses, and results of breast, bone, and skin cancer tests, as well as the results of lab work following miscarriages.

By law, medical records and documents containing personal identifying information must be disposed of in a way that protects privacy, and leaving them at a dump is probably illegal, privacy lawyers and hospital officials said. Violators face steep fines.

A Globe photographer discovered the records July 26 when he was dumping his trash at the Georgetown Transfer Station. When he got out of his car, he said, he saw a huge pile of paper about 20 feet wide by 20 feet long. Upset that the paper wasn’t being recycled, he looked more closely.

The photographer said he saw health and insurance records from at least four hospitals and their pathology groups — Milford, Holyoke, Carney, and Milton — mostly dated 2009. The Globe notified the hospitals. It is unclear how many other hospitals’ records might have been discarded in the dump.
