People are confusing the two different types of CHC funding.
There is fast track continuing healthcare which is awarded without a DST being completed if the person meets the criteria of being terminally ill with a rapidly deteriorating condition. This is reviewed after 12 weeks.
Fully Funded continuing healthcare is awarded after a full DST and is for people whose nursing care needs are of a nature, complexity, intensity or level of unpredictability that is above and beyond the typical care that would be provided by nurses in a nursing home.
It's not diagnosis specific or even how 'unwell' someone is, it's about how complicated it is to manage their care.
The NHS pays a weekly contribution called the funded nursing contribution to anyone needing nursing care as NHS care is 'free at the point of delivery'. If someone's nursing needs costs more than the funded nursing contribution provides for then this is where CHC funding becomes relevant
Examples:
pressure sores that are not responding to a treatment regime requiring specialist support.
Moving/hoisting that requires more than the standard 2 people due to extreme fragility or complexities in how a person needs to be moved.
Medications requiring titration or daily decision making e.g. lorzepam to manage behaviours.
Challenging behaviours that don't readily respond to standard reassurance techniques
Regular fits or other conditions that may require daily nursing intervention e.g. very unstable blood sugars.
