Positive Impact of Decontamination
![Page 11: NHS Quality conference - Tom Lister](https://reader034.fdocuments.in/reader034/viewer/2022042607/5599df781a28ab3f318b4595/html5/thumbnails/11.jpg)
The negative impact of decontamination:
Time constraints
Exit block from ED?
Only able to be carried out in vacated rooms
What do we do in bay scenarios?
