Breaking News 3: About 1,800 Patients Secretly Recorded by Spy Cameras in California Hospital Delivery Rooms

You can’t imagine that there are hidden cameras in the hospital’s labor and delivery rooms. The places that should be the most private are installed spy cameras.

On April 3, 2019, CNN reported a piece of shocking news that about 1,800 women were secretly recorded in California labor and delivery rooms.

Patients’ faces and their delivery processes were all recorded, completely and clearly.

California Sharp Grossmont Hospital

“It’s the most fundamental breach of privacy,” said Allison Goddard, a lawyer representing over 80 women who say they are part of the victims.

According to Allison, in the videos, she can see everything clearly including how women were rolled into the operating room, how they were prepped for surgery. And she can even see the birth of the baby.

Everything is just recorded extremely clearly and patients have no privacy!

It’s even worse that the videos were saved on desktop computers, and some without the need for a password. In other words, anyone can access the videos without an effort!

Why did a hospital install spy cameras in 3 of private rooms?

According to the hospital’s document, the installation of the hidden cameras is to catch a thief.

The file states that around May 2012, drugs were stolen from medial carts in operating rooms, so the hospital installed motion-detecting cameras on the carts to captured who stole the drugs.

John Cihomsky, Sharp Healthcare’s vice president of public relations and communications, said, “Although the cameras were intended to record only individual in front of the anesthesia carts removing drugs, others, including patients and medical personnel in the operating rooms, were at times visible to the cameras and recorded.”

Hospital is a private zone. “There are a very long list of reasons why taping, recording, videoing for anything other than medical or treatment purposes has to be strictly off-limits, because you're trying to protect people who can't protect themselves.”, said Art Caplan, head of the Division of Medical Ethics at the New York University School of Medicine.

And a lot of people have commented on this case: it’s totally unacceptable for a hospital to install hidden cameras in private rooms recording patients’ most fragile times. It’s undoubtedly a severe violation of patients’ privacy.

Currently, the case remains ongoing and the hospital was unable to comment further about this case.

We will keep updating the case here once the authorization updates the process of the case.
