It's called 'delayed discharge' where I work. It's caused by a number of things.
Paperwork completed and sent to the correct team to be allocated to a social worker. Then the patient has to wait for the social worker to assess the patient, however this often is delayed as relatives want to be present at the assessments or we can't get the relatives to come in to sign the paperwork in the first place as they are working or busy.
Then an ot and physio report is needed (why the physio and ot notes that the ward staff use can't be accepted I don't know as they contain the same information) which can take a while.
Then the social worker makes their decision ie care package (which can take a week or so to organise) even longer if there is issues around self funding, catchment areas etc.
If the patient is for a care home then its longer. The social worker finds a list of homes that 'fit' the patients needs as the care homes have strict criteria for the patients that they accept and hands this list to the next of kin to have a look at the homes and decide. Then the homes that are chosen by the family are asked to assess the patient on the ward. If the patient fits the criteria then there is normally a delay as the homes don't accept new residents on Fridays, over the weekend, after 4pm and they want x y or z providing for the patient such as hospital beds or air mattresses etc. So these have to be prescribed,funding agreed and equipment delivery arranged.
By this time the patient has probably developed a chest infection/urine infection/deranged bloods so is now medically unfit which means the whole process is ground to a halt and has to be restarted once the patient is fit. It can't all just be reinstated, it has to be started from the beginning again
This is a simple discharge process to be honest. It doesn't take into account
-- relatives arguing over funding,
-son and daughter arguing over which home mum goes into,
-the relatives that ignore the phone calls and messages asking them to ring as dad is fit for discharge and has been for three weeks but we can't do anything as they have to signed the papers
-the next of kin to bring the house key in so mum can actually get back in the house.
-next of kin to bring the bed downstairs to provide a micro enviroment (bed,commode all in the living room, like a bedsit)
-family members that insist mum cannot go home even with a four times a day care package and must go to rehab ( even though physio,ot and social workers say patient doesn't meet the criteria)
Then there are the patients that refuse care packages, go home, fall and are readmitted back to the ward as a failed discharge (which is a bad mark against the ward)
There's also the care homes that refuse to accept their residents back as their needs can no longer be met ie the care home has had enough of the lady that sings at 2am every night or fights bites and swears.
