Infection Control Practices

Greetings! I was wondering if you all would be willing to share your institution's practice when it comes to supplies in an isolation room. I in an ICU that stores more than 24 hours worth of syringes, needles, gauze, tape, IV start materials, sat probes, kerlix, vacutainers, statlocks, yankauers, nasal cannulas, salem sumps, & more (all in their original wrappings) in the pt rooms. They don't dispose of what is in the pt rooms after an isolation pt is in the room. The rooms are all used for patients that need isolation as well as patients that don't. Nurses & techs have questioned this and are told it isn't cost effective to dispose of what is in the room & our infection control person says it isn't necessary. We are lucky if the isolation carts have gloves in them, much less supplies. This has bugged me since I started working there & I am about to tackle this issue in my unit. I would like to know what other facilities do. Thanks in advance.
