Bristol Stool Chart for Carers: Assessing Bowel Health in Care Settings
Care home and community care reference - Updated September 2026
Why the Bristol Stool Chart Matters in Care Settings
NHS England publishes a carer-facing Bristol Stool Chart and describes it as a visual aid to help someone identify whether they are experiencing constipation. The reason it earns its place in care settings is that it is an objective, visual, standardised scale that does not depend on the person being able to describe what they passed. For carers supporting individuals who cannot reliably describe their symptoms - including people with dementia, learning disabilities, acquired brain injuries, or those receiving end-of-life care - the chart transforms a subjective observation into a documented clinical data point.
Constipation is one of the most common - and most dangerous - unaddressed health conditions in UK care homes. Faecal loading and impaction can cause confusion and delirium (especially in older adults), urinary retention, loss of appetite, abdominal pain, and in severe cases, bowel obstruction. Regular bowel monitoring using the Bristol chart prevents these complications through early identification and intervention.
How to Use the Chart in Care Assessment
The chart should be used consistently across shifts and between carers. Consistency is the core value: one carer's interpretation of "soft" is not the same as another's, but Bristol Type 4 is a standardised descriptor. Standardised documentation prevents the inconsistency that leads to missed escalation.
Note the stool type at each bowel movement. A simple chart on the bathroom wall or in the care plan folder reduces reliance on memory.
Log the type number, date, time, frequency, and any associated symptoms (blood, mucus, pain, urgency). Use the care plan or keyworker notes - not this website's tracker for clinical data.
Compare against the individual's baseline. A shift from their normal (e.g., usually type 4, now consistently type 2) is more meaningful than the absolute type.
Apply the escalation thresholds below. Act promptly - delayed response to bowel problems in elderly or vulnerable patients causes avoidable harm.
Escalation Thresholds for Carers
Encourage fluids, offer fruit or high-fibre food, increase mobility if possible. Document. If 5 days with no movement: contact GP.
Contact GP. Do not administer laxatives without medical authorisation unless they are already prescribed in the care plan.
This triad may indicate faecal impaction with delirium. Urgent GP or 111 assessment. Do not wait.
Do not treat with anti-motility medication. This may be overflow around impacted stool. Urgent GP assessment required.
Consider C. difficile (especially if recent antibiotic use). Stool sample required. Infection control precautions (separate toilet, gloves, apron, hand hygiene with soap - not just gel).
Document and notify GP or nurse. In a non-verbal patient, fresh blood without an obvious explanation (known haemorrhoids) warrants prompt assessment.
Special Considerations: Dementia and Learning Disabilities
Individuals with dementia often cannot verbalise that they are in pain or discomfort from constipation. Behavioural signs of bowel discomfort include increased agitation, refusal of food and drink, rocking, facial grimacing, and withdrawal. The Bristol chart provides a way to identify and document bowel problems objectively without relying on self-report.
NHS England's carer-version Bristol Stool Chart, published in July 2023, was produced for its constipation campaign for people with a learning disability and the people who care for them. It uses simplified visual language and large-format illustrations, and tells the carer to contact the GP surgery of the person they care for if a poo does not look like type 3 or type 4. The chart is available to download free from NHS England's website.
STOMP (Stopping Over Medication of People with a learning disability, autism or both) is NHS England's programme on psychotropic prescribing. Many of the psychotropic medications involved have constipation as a significant side effect, which is one reason regular bowel monitoring matters in these settings.
Continence Care and Bristol Type
Bristol type also informs continence care product selection. Firm types 3-4 are manageable with standard continence pads. Types 5-7 (loose to liquid) require higher absorbency products and more frequent changing to prevent skin breakdown and pressure ulcer risk. Consistent type 7 diarrhoea in a care setting should trigger a continence review with the district nurse or continence specialist, as well as bowel assessment for the underlying cause.
