Waste in Rooms

When going a shift on Saturday I was alarmed to notice several used auroscope earpieces stacked up on the desk in one of the rooms. I spoke to the Health Care Assistants who told me that this was a common occurrence and that used urine sample bottles & test strips are commonly left out as well. There are clinical waste bins in all the consulting rooms; I would like to request that doctors use them as there are obvious infection risks in not doing so.
