Bristol Stool Chart for Carers: Assessing Bowel Health in Care Settings

Care home and community care reference - Updated April 2026

Note for care professionals: This page provides a reference guide based on NHS England's Bristol Stool Chart for Carers (2023) and general clinical guidance. It is not a substitute for your organisation's clinical procedures, care plans, or the specific guidance of the patient's GP. For clinical documentation of patient bowel data, always use your organisation's approved record system.

Why the Bristol Stool Chart Matters in Care Settings

NHS England has officially recommended the Bristol Stool Chart for use in care settings precisely because it provides an objective, visual, standardised scale that does not rely on verbal description. 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.

O
Observe

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.

R
Record

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.

C
Compare

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.

E
Escalate

Apply the escalation thresholds below. Act promptly - delayed response to bowel problems in elderly or vulnerable patients causes avoidable harm.

Escalation Thresholds for Carers

No bowel movement for 3 days
Monitor

Encourage fluids, offer fruit or high-fibre food, increase mobility if possible. Document. If 5 days with no movement: contact GP.

No bowel movement for 5+ days
GP contact

Contact GP. Do not administer laxatives without medical authorisation unless they are already prescribed in the care plan.

Abdominal distension + no bowel movement + confusion
Urgent

This triad may indicate faecal impaction with delirium. Urgent GP or 111 assessment. Do not wait.

Overflow diarrhoea (liquid type 7 in a usually constipated patient)
Urgent

Do not treat with anti-motility medication. This may be overflow around impacted stool. Urgent GP assessment required.

Type 6-7 with fever in care home setting
Urgent + infection control

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).

Blood in stool (any type)
Notify GP

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.

For people with learning disabilities, NHS England's carer-version Bristol Stool Chart (2023) was specifically designed for use in supported-living and residential settings. It uses simplified visual language and large-format illustrations. The chart is available to download free from NHS England's website and is widely used in community learning disability nursing.

STOMP (Stopping Over-Medication of People with a Learning Disability) guidance notes that many psychotropic medications prescribed for people with learning disabilities have constipation as a significant side effect. Regular Bristol chart monitoring is a recommended safeguard.

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.
