Again, I agree. On my ICU, the drugs keys had a big item attached to stop this because it was so common. People are in a hurry, grab the keys from a colleague, open the drug cupboard and get the drugs, then need their hands to carry the drugs, possibly a fluid bag or two, so shove the keys in their pocket. Only when someone else needs to use the drug cupboard does the search begin, and a nurse from the shift before says 'I've got them, I'll be there in 10 minutes!'
Handover sheets should go in the confidential waste bins but again, people get behind, handover, perhaps stop to check their notes are correct, that pressure area charts are signed, that cannula monitoring forms are complete, that everything is properly documented to do with positioning, etc., so many things, and then the last thing on their mind is the slip of paper in their pocket.
I think it's worth remembering that this opening statement from the prosecution is only a sketchy outline of the case against the defendant. Then we'll hear a sketchy outline of the defence case. The actual evidence will be painstaking. In such a high care environment, everything is documented, so I expect they'll be moving slowly through documents, tracing steps, establishing timelines, etc., very carefully.
On normal wards it isn't uncommon for one overarching summary of care given to be made at some point in the shift. E.g. 'Patient slept well, no pain reported.' Areas such as ICU have extensive notes because the condition of patients can change so rapidly.
