Observable discomfort in people with dementia: does it point to pain or another cause?

Jenny T van der Steen, Elizabeth L Sampson and Nele JA Van Den Noortgate explain the background to their longer article published in the May/June edition of the European Journal of Palliative Care.

Pain is common in older people, and probably no less so in people with dementia. However, risk of inadequate treatment is increased if they are unable to self-report pain. The practice of systematic observation of possible pain indicators is favoured to help detect pain and indicate intensity; for example, through direct observation or through recall of facial expressions, vocalisation, and changes in activities of daily living (ADL). As many as around 30 such pain tools have been developed. Some other tools observe general discomfort or distress that may or may not indicate pain in people with dementia.

We are members of the Palliative Care Working Group of a European Union COST Action (Pain Assessment in Patients with Impaired Cognition, especially Dementia), that is geared towards developing a pain toolkit. As such, we wondered if, and how, these tools differed. We therefore reviewed in detail eight exemplary pain and discomfort tools. This required thorough and in-depth reasoning and enjoyable, complicated discussions. Despite great variation among the tools, we found some differences between the items of pain and discomfort tools. For example, discomfort tools had more subjective items. However, only a few items were specific to either type of tool, such as ‘guarding’ for pain tools and ‘serenity’ for discomfort tools.

Next, via our networks, we had an interesting and intense debate regarding the pros and cons of two distinct approaches. The first is direct observation of standardised items and is used to observe pain with the PAINAD (Pain Assessment in Advanced Dementia Scale) (Prof. Ladislav Volicer and colleagues). The second builds a baseline of individualised behaviour when patients are content or distressed. A later assessment is compared with the baseline. This is used in the DisDAT (Disability Distress Assessment Tool) (Dr Claud Regnard and colleagues). The PAINAD developers assume that pain is expressed by a limited number of signs observable in two minutes. The DisDAT team, by contrast, believes that expression of distress is highly individual and stable over time, and that behaviour cannot indicate a specific cause.

We extended the debate with PhD students and teachers attending the COST spring school in Ghent in March. How might a tool to assess non-pain distress look? Should we drop the guarding item from pain tools if guarding is uncommon? How representative is the case of a lady whose individual pain indicator was fiddling with her left trouser leg?

There is little research to help identify the best approach, or that compares pain and discomfort tools head-to-head. It might depend on the situation such as availability of a familiar caregiver, time, and a stable condition. Moreover, in practice, assessment is not enough: observations, whether with pain or discomfort tools, should lead to finding a cause. Still, we feel that even imperfect approaches and tools may help recognise behavioural cues as possible indicators of pain or discomfort – an individualised approach and systematic assessment remain at the heart of palliative care.
