Along with many units we are examining our disinfection routines to see if there's a way to save energy, emissions and money. We use 5008H for which the manual states that a delay of up to 72hrs is acceptable.
We currently run three shifts a day and disinfect 4 times. This means disinfection is done approx 06.00 11.30, 17.00 and 23.30. I've considered removing the early morning disinfection routine and would be really interested to hear people's thoughts and experiences on the subject.
We do high vol HDF treatments and change ultrafilters as per OEM instructions.
We have different equipment but same manufacturer's guidance. We do not routinely disinfect each morning, just post each treatment in centre, as operational 6 days per week. Though 72 hours is acceptable we have always used 48 hours as guidance to users, though that is purely historical.
For home patients we also ask them to do an additional disinfection if they have a a two day break.
We have a mix of HDF, DF and standard HD equipment.
No start of day disinfections at Wolverhampton but they are carried out after each session. We also carryout a double disinfect from an isolated BBV machine is to be "de-isolated" and returned to general machine pool.
I'm old enough to remember when we used to store our HDF machines in a bacteriostatic low level peroxide solution overnight, and would internally disinfect after sitting idle for 4 hours. Changed days We stopped the automatic morning disinfect some years ago. I tried requesting the evidence FMC based the 72hrs on but didn't get anything back. I'm sure they would have to validate this before stating in the manual.
We set our machines for an automatic thermal cycle mid morning so that any machines not in use will be disinfected daily and be ready for use, and not left to stagnate in a run up bay or plant room.
