Cripes don't attempt to read the DST without a stiff drink and a donut!
The way I usually try and explain it is that medical is anything that requires carrying out/prescribing by a medical professional or regular oversight by a medical professional.
So for physical needs basically anything that district nurses would do rather than home carers in the community e.g dressing wounds, taking bloods, inserting catheters, complex PEG feeding, dealing with complex continence issues and administering certain medications would be medical.
Providing personal care (emptying catheters, changing pads, feeding and washing) would be social care.
It gets a bit trickier to define with mental health conditions e.g. dementia but again it basically boils down to does this person's needs require a registered mental health nurse overseeing their care on a day to day basis or can their needs generally be managed by a care assistant as part of the normal routines of the care home.
So someone violent, or extremely distressed, or someone requiring medication to be administered covertly because they refuse to take it would be seen to have medical needs.
The DST states that these medical needs must be considered in terms of their Nature, Complexity, Intensity and Unpredictability when deciding if the funding balance should be tipped into needing to be fully funded by the NHS.
