Cover that stethoscope!

We have placed a great deal of emphasis on hand hygiene in the healthcare setting over the past few years, but unfortunately little is said about the stethoscope. Found hanging from almost every doctor's neck, the device is used many times in the course of a day, but most physicians seldom wipe it down. Studies have shown it to be contaminated with common pathogens. So I was excited to see an article in the Boston Globe about Dr. Richard's Ma invention, a disposable plastic cover (shown in the photo). Do you think physicians are any more likely to use the cover than wiping the stethoscope down?
