I know when the spares were to be withdrawn for the 4008 machine we were given 7 years notice. I think Gambro gave 10 year notice on the AK200s machines.
Its a difficult one. I know when I started my old boss told me that machines would last 7 years or around 20,000hrs. We were talking Ak100 machines here and after 7 years they probably would be a bit problematic. Personally I haven't had a 5008 keep returning to the workshop with various faults you may put down to as "the machine is just old". I have seen them return to the workshop on more than one occasion but that's because it wasn't repaired properly in the first place! (went through heat, went through test and now I'll chuck it back out syndrome)
These days I personally feel that age or hours of machine is no longer that important as long as parts can be bought. So if most if not all companies will give 7 years notice I see the managing of that period more important. A machine replacement program won't help you if you're going to have to move to a different machine.
We've had brand new machines in the past which have been more problematic than the older ones - sometimes there are just gremlins in there, sometimes the manufacturer has changed a manufacturing technique or supplier (leaking rinse chambers, sub standard gold plating on connectors, plastics cracking anyone!?)
Guidance is only guidance at the end of the day - it isn't law
The guidance would be better off being left at:
The routine maintenance of the equipment used for renal replacement therapy is essential and the service history of each
machine should be documented fully throughout its use-life by the renal unit technicians.
Although it is possible to keep a dialysis machine operating safely for many years, practical considerations of obsolescence and maintenance costs should be considered when it comes to replacement. When a particular model of a machine becomes obsolete, companies generally only undertake to supply replacement parts for seven years.
We've seen from other posts the variation in how long people will run their machines for. Guidance is one thing - reality with directorate accountants and clinicians can be a completely different beast!
