Municipal-hospital workers aren’t happy with the new electronic medical-record system that’s costing taxpayers at least $764 million.

The system, dubbed Epic, launched Saturday at Elmhurst and Queens hospitals, and employees are already complaining that newly generated medical records are being lost.

One veteran Elmhurst Hospital employee described how a new dictation system for doctors to input postoperation notes isn’t retaining the reports.

“For two days, the doctor couldn’t find the operating report in the Epic system because there was a delay,” he said.

“Let’s says a patient comes back to the ER after experiencing complications from a procedure. The doctor could read the progress notes to find out what happened, but for two days, they couldn’t see the operating report.”

Insiders at NYC Health + Hospitals have warned for weeks that the network should have extended its deadline to launch the system, citing at least a dozen warnings that doing so prematurely
could threaten patients’ safety.

Some insiders have even said that Dr. Ramanathan Raju, head of the agency, told employees that he feared losing his job if he didn’t make Epic’s April 2 deadline. Raju denied facing termination.

Ian Michaels, an agency spokesman, said Sunday there have been “minor issues” associated with the launch, but declined to elaborate.

About 900 city employees and consultants were assigned to implement and troubleshoot the transition for the two hospitals.

According to one source, some employees have even been sleeping over at the agency’s Water Street offices to ensure the launch goes smoothly.
