8. Module 8 · Environment & Prevention
Prevention is better than de-escalation
The best way of dealing with challenging behaviour is prevention: heading it off so that escalation happens less often or not at all. This is usually easier, more dignified and safer than de-escalating afterwards. Prevention starts with the causes and triggers (Modules 2 and 3). First, recognise and meet needs – basic needs such as freedom from pain, going to the toilet, food, drink, warmth, movement, rest and attention, as well as individual needs – before unmet needs turn into challenging behaviour. Second, avoid triggers: know the general and individual triggers (Module 3) and avoid them or handle them differently, for example by announcing care, working calmly and gently and reducing sensory overload. Third, adapt the environment (see below).
Fourth, relationship and communication: a familiar, trusting relationship and respectful communication that announces what will happen help the person to feel safe, so fear, hurt and resistance arise less often. Fifth, structure and meaningful activity, especially in dementia: a clear daily routine and occupation against boredom and restlessness. Sixth, attentive observation: notice early warning signs and respond early (Module 4). Seventh, documentation and handover: record triggers and approaches that worked and pass them on in the team, so that everyone acts preventively (NICE, 2015). Prevention addresses the causes instead of dealing with the consequences.
Learning objectives of this module
- You understand prevention as the best approach (preventing instead of de-escalating).
- You meet needs and avoid triggers.
- You adapt the environment/milieu.
- You use relationship, structure, observation and documentation.
The milieu as a de-escalation factor
The environment, often called the milieu, is an important and frequently underestimated factor. It affects wellbeing and behaviour, especially in dementia: an unfavourable environment can trigger challenging behaviour, a favourable one can reduce it (BMG, 2007).
Unfavourable factors include sensory overload – noise, bustle, a television running, many people, glaring light – which overwhelms people with dementia in particular and can lead to restlessness, aggression or withdrawal; cramped, crowded spaces; time pressure in care routines, which transfers to residents; disorientation in a confusing environment, which creates fear; conflicts among residents; and a cold, uncomfortable atmosphere. Favourable factors include a calm, homely atmosphere; the right level of stimulation – neither overwhelming nor boring, with quiet areas and places to withdraw to; orientation and security; enough space; structure and meaningful activity; and a calm, unhurried mood among the staff themselves. In practice, care teams can limit noise and television, create quiet corners, support orientation, offer activities and avoid passing on their own stress (NICE, 2018).
Prevention
| Approach | In practice |
|---|---|
| Meeting needs | Pain!, toilet, hunger, rest, attention |
| Avoiding triggers | Announcing, gentle, avoiding individual triggers |
| Adapting the milieu | Reducing sensory overload, calm, orienting |
| Relationship/structure | Trust, communication, occupation |

Needs orientation as the best prevention
The most fundamental prevention is needs orientation: recognising and meeting a person’s needs before unmet needs lead to challenging behaviour. This follows from the basic understanding in Modules 1 and 2 – challenging behaviour is usually the expression of an unmet need or distress. Needs orientation covers three levels. Physical needs: above all freedom from pain (pain is a common cause, Module 2, so good pain management is important prevention), timely toilet visits, food and drink, warmth, movement, rest and sleep. Psychological needs: security instead of fear, control and self-determination instead of helplessness, respect instead of hurt, attention and relationship instead of loneliness, and demands that do not overwhelm. Meaning and participation: meaningful activity, structure and stimulation, especially in dementia.
Needs orientation means perceiving needs attentively – including those expressed only through behaviour (‘detective work’, Module 2) – with the help of the person’s biography and information from relatives. It also means meeting needs proactively: accompanying the person to the toilet in good time, treating pain, giving attention and offering activities. Preventing challenging behaviour therefore largely coincides with good, person-centred care.
The calm environment
In one living area, restlessness and aggressive situations increase, especially in the late afternoon in the loud, crowded common room with the television running and a lot of commotion. The team analyses the situation and identifies sensory overload as a factor. It adapts the milieu: less noise, with television and radio limited, quieter areas and places to withdraw to, a calmer atmosphere, more structure and meaningful activity. It also pays closer attention to needs such as going to the toilet, pain and rest. Restlessness and aggressive situations decrease markedly.
More control instead of a better milieu. The same living area, but this time the team reacts differently. The common room stays loud, and the television keeps running. Residents who become restless are taken to their rooms early, and the team asks the doctor for something to calm them. Over the following weeks some residents are drowsy during the day and unsteady on their feet; in the late afternoon the restlessness continues.
How to classify it: The causes – sensory overload and unmet needs – remained untouched. Sedating medication does not remove them and carries risks such as falls; for antipsychotics in dementia, guidelines advise use only when there is a risk of harm or severe distress (NICE, 2018). Keeping a person in their room against their will, or sedating them in order to restrict their movement, can be a measure that deprives them of liberty and needs consent or court approval (section 1831 BGB). The first step is always to look for causes and adapt the milieu.
| Aspect | Case study: adapting the milieu | Version B: more control |
|---|---|---|
| Analysis | sensory overload identified | no analysis |
| Action | less noise, quiet areas, activity | residents taken to their rooms, medication |
| Needs | toilet, pain and rest checked | not considered |
| Risks | few | drowsiness, falls, deprivation of liberty |
| Outcome | restlessness decreases markedly | restlessness continues |

Exercise: How do you prevent challenging behaviour – by meeting needs, avoiding triggers, adapting the milieu, and building relationship and structure? Do you perceive needs attentively and meet them early? Is the environment in your area calming and easy to find one’s way in, or does it cause sensory overload?
Show suggested approach
Take a short walk through your living area at the time of day when restlessness is greatest and note: 1. What do you hear and see (noise, television, light, number of people)? 2. Are there quiet places to withdraw to, and is it easy to find one’s way? 3. Which needs are typically unmet at that time (toilet, drink, pain, rest, activity)?
Choose one change that the team can try for two weeks – for example switching off the television in the late afternoon, offering a regular drink round or setting up a quiet corner. Agree in the team who observes what, document the effect and discuss it at the next team meeting.
- Prevention is usually easier, more dignified and safer than de-escalating afterwards.
- The basis is needs orientation: meet physical, psychological and social needs before they turn into distress.
- The milieu matters: reduce sensory overload, time pressure and disorientation; create calm, orientation and activity.
- Relationship, structure, early observation and good documentation make prevention a team task.
