Hospital installs hand washing surveillance cameras

Doctors and nurses in the ICU at Long Island’s North Shore University Hospital are being watched by 39 video cameras in an effort to increase compliance with hand washing. According to a report hand washing compliance is up from less than 10% to 90% since the program started.

Cameras are positioned near the doors of patient rooms and at sinks Patients are not being videoed. The real-time feed is observed by workers in India. Staff failure to wash hands is noted, and the results are posted on electronic bulletin boards in the unit. So far, miscreants are simply talked to.

"No one's been fired, no one’s been written up but there have been one-on-ones," the news story says and, “Infections have decreased though an exact percentage was unavailable.” That raises the question of how they would know if infections have really decreased if the exact percentage is unavailable. And there’s another question, “Is the decrease statistically significant?”

This venture, while well-intended, seems like a bad idea to me. I suppose you are thinking, “Could Skeptical Scalpel really be against hand washing?” Well, I’m not. But what seems logical and correct sometimes may not be. For example, everyone knows that sinks with faucets that have electronic eye sensors are cleaner and better to use in hospitals than sinks with manual faucets, right?

A study presented at a meeting of the Society for Healthcare Epidemiology of America last year by a group from Johns Hopkins concluded the following: Electronic faucets were more likely to become contaminated with Legionella spp. (species) and other bacteria after water system disruption. Electronic faucets were less likely to be disinfected after chlorine dioxide remediation. Electronic faucet components may provide points of concentrated bacterial growth. These findings led to removal of all electronic faucets from clinical areas in our institution. [Emphasis added.]

Washing hands with soap and water may cause dryness and irritation resulting in skin breakdown. It may be that constant, obsessive hand washing and use of gels could promote the emergence of resistant organisms.

Another potential issue with the video observation is a false accusation of failure to wash. Patient rooms and patients themselves are not being watched. Let’s say a nurse went into a patient’s room to tell him something and didn’t touch anything. A person in India watching a video from a camera focused on a door or sink would not be able to tell that. If the nurse doesn’t wash her hands when she leaves the room, is she going to be cross-examined?

And what about cost? How much does it cost to install and maintain 39 video cameras, stream the video to India and pay people there to watch the monitors and feed back the information 24 hours per day? Remember, they have no proof that video surveillance reduces infections.

What does this scheme say about the relationship of the professional staff to the hospital’s administration? More problematic is the fact that even though they know they should, doctors and nurses at a major medical center apparently cannot be trusted to wash their hands unless they are spied upon. What else do they not do?

Instead of issuing press releases about this ill-advised program, hospital management might want to consider investigating why their staff is non-compliant.
