What Is NHS Continuing Healthcare (CHC) and Who Can Qualify?
“Primary health need” is the central test for NHS Continuing Healthcare, and one of the phrases families find hardest to translate into ordinary life.
“Primary health need” is the central test for NHS Continuing Healthcare, and one of the phrases families find hardest to translate into ordinary life.
It does not mean that somebody must have one particular diagnosis, be receiving treatment in hospital or need a registered nurse every minute of the day.
The assessment looks at the overall picture of need and asks whether, taken together, those needs are primarily health needs rather than needs a local authority could lawfully be expected to meet as social care.
The four characteristics
The National Framework uses four characteristics to help understand the totality of need: nature, intensity, complexity and unpredictability.
They are not four separate boxes that somebody must all “pass”.
They are ways of asking what the needs are like, how much care they require, how different needs interact and how difficult they are to anticipate and manage.
Nature: what are the needs and what do they involve?
Nature considers the type and effect of the needs and the interventions required to manage them.
Two people may both need help eating, for example, but one may simply need meals prepared while another has swallowing difficulties, aspiration risk, specialist feeding requirements and close monitoring.
The task label can look similar while the underlying need is very different.
Intensity: how much and how often?
Intensity considers quantity, severity and continuity.
A person needing occasional reassurance is different from somebody requiring repeated interventions throughout the day and night.
Ask how often care is needed, how long interventions take, whether needs are sustained and what happens if support is delayed.
Complexity: how do the needs interact?
Complexity is often visible where one problem makes another harder to manage.
Cognitive impairment may prevent somebody understanding diabetes treatment. Parkinson’s symptoms may combine with falls, swallowing difficulty and medication timing. Behaviour may be affected by pain that the person cannot communicate.
The assessment should look at the interaction, not divide the person into unrelated medical labels.
Unpredictability: how easily can needs change?
Unpredictability concerns unexpected changes and the level of skill or response needed when they happen.
A condition does not have to be chaotic every minute. The question can include whether deterioration, seizures, behaviour, breathing, blood sugar, falls or other needs fluctuate in ways that create significant risk or require timely intervention.
Why a list of diagnoses is not enough
A diagnosis tells you what condition somebody has. CHC eligibility depends on the needs arising from the condition and their overall quality and quantity.
This is why two people with the same diagnosis can receive different CHC decisions without either decision automatically being inconsistent.
The useful evidence is what actually happens: frequency, severity, intervention, risk, response and interaction between needs.
Do not turn the four characteristics into magic words
Simply writing “complex” or “unpredictable” repeatedly does not establish eligibility.
Describe the facts that demonstrate the characteristic. What changes? How often? Who has to respond? What skill is needed? What is the consequence if the intervention is late or ineffective?
Strong CHC evidence describes the person rather than trying to imitate the language of the framework.
