Pain Assessment in Advanced Dementia Scale (PAINAD)
Observational pain scale for non-verbal patients with advanced dementia. Assesses 5 behavioural indicators of pain: breathing, negative vocalisations, facial expression, body language, and consolability. Score 0-10; higher score indicates more pain. Validated by Warden et al. 2003. NICE CG103 and BSG recommend structured pain assessment tools in patients who cannot self-report.
Score interpretation
PAINAD 0 -- no behavioural signs of pain detected at this assessment
→ Continue regular assessments (at least once per shift and before/after procedures); document PAINAD score; ensure comfort measures: repositioning, pressure care, mouth care; carers and family as partners -- ask if they have observed pain behaviours at other times; reassess if behaviour changes.
PAINAD 1-3 -- mild pain or discomfort behaviours
→ Non-pharmacological measures: repositioning, warmth, gentle touch, music therapy, massage; distraction and reassurance; address possible causes: check for pressure sores, urinary retention, constipation, joint contractures; if non-pharmacological insufficient: consider regular paracetamol 500-1000 mg QDS (safe first-line in dementia); reassess PAINAD after 30-60 minutes; document response to intervention; carers and family engagement.
PAINAD 4-6 -- moderate pain behaviours; analgesia required
→ Pharmacological analgesia: regular paracetamol (if not already prescribed) as first-line; if inadequate: consider opioids -- morphine 1-2.5 mg SC/PO PRN (4-hourly, reduce dose in renal impairment and frailty); review and treat underlying causes (repositioning, pressure care, bowel care); avoid NSAIDs if possible (renal/GI risk in elderly); dementia team or pain team input if refractory; document PAINAD before and after intervention; reassess at 30-60 minutes; family discussion about pain management goals.
PAINAD 7-10 -- severe pain; urgent assessment and treatment required
→ Urgent analgesia: opioids (morphine or equivalent) titrated; consider subcutaneous morphine 2.5-5 mg SC PRN if oral route not available or swallow unsafe; review syringe driver for continuous SC opioid/midazolam if distress prolonged; palliative care team urgent input; rule out acute cause: acute abdomen, fracture, urinary retention (catheter), acute chest pain -- ECG, bloods; family/carer meeting regarding pain management, goals of care, and ceiling of treatment; if end of life: Liverpool Care Pathway equivalent, anticipatory medication for pain and agitation; document all assessments and management.
