Hey Dot,
Thanks for asking for my thoughts. Bottom line is this: I do not think in the hospital setting you can properly sterilize nebulizer cups for reuse. We use more care at home than the guidelines provide for a hospital and you don't have nearly the issues of MRSA etc. But more importantly is the inability for staff to be compliant. I was curious re our hospital's infection control procedures and googled and found that with c-diff, following the hospital's OWN policies was horrible. Only about 50% of doctors followed, nurses were about 80%. (RTs may be better or worse? Turn over could be an issue as well.) And from the personal experience, we see stupid stuff all the time: for instance staff cleaning my fil button and then opening the door with the same gloves. And what do you think my mil is going to touch leaving the room? Or the CF mom who said how the doctor doing her son's lung transplant scrubed in and then turned the light switch on? And then you have issues of mold growing in the sink (which our clinic rooms do because they have overflow values and the hand soap which bubbles goes through that when draining and is more susceptible to mold. So even if you have the best policy for sterilization/cleaning, I sincerely doubt you will have compliance and asceptic handling of more than 50%. (See the example of the RT who dropped it on the floor and then wanted to reuse.) This is coming from a momma bear who is clearly anxious in the hospital setting, but it is rational when you read the studies of how these horrible CF bacteria are transferred and how much easier it is to transfer than believed. And as you said, it is cheeper to avoid the infection than pay for it when more harm is done.
I am not, though, oblivious to the cost. I have a business background and understand that if you lose money you won't stay in business (or non-profit) to serve anyone. And that insurance companies control reimbursement. However, I also think that there is much more to the cost than the mere cost of the disposable nebulizer. (I also wonder if the studies really show that much is wasted in using disposables???). The cost of RT time in cleaning, baby sterilizers (which would need sterilization after using for one patient--and I wonder how and IF that could even be down), the cost of supplies to clean, and then the training cost and the cost of disposing ones that aren't properly cleaned anyway, and of course the cost of litigation if someone is infected, as well as the loss of reputation if that happens. On the other hand, it might be possible to work with the CF center or the CFF pharmacy to get the disposable at an even better rate than you currently can.
Anyway, that's where I'm coming from. Thanks for listening Dot.
