Hello all, I'm pretty new to this site...actually just stumbled upon it earlier today while trying to find some blasted research. I am a CNA in an ICU on days and we are constantly bothered and interrupted by immense flows of visitors and families. We used to be able to lock our doors most of the day, but the hospital management decided that we needed to be a more open facility, despite the protests from the actual workers of the units. My boss has said the upper management would rethink their decision about the open door policy if the staff can provide research and information on locked door units. I suppose they are interested in seeing if a locked ICU has the same efficiency AND family satisfaction as an open ICU. I've been on google for a couple hours now and haven't found much in the way of "research". Please, If anyone knows of any data, it would be immensely beneficial, since we might be able to close our doors once more. Thanks!
