BackgroundDe-escalation techniques are a recommended non-physical intervention for
the management of violence and aggression in mental health. Although
taught as part of mandatory training for all National Health Service
(NHS) mental health staff, there remains a lack of clarity around
training effectiveness.AimsTo conduct a systematic review of the learning, performance and clinical
safety outcomes of de-escalation techniques training.MethodThe review process involved a systematic literature search of 20
electronic databases, eligibility screening of results, data extraction,
quality appraisal and data synthesis.ResultsA total of 38 relevant studies were identified. The strongest impact of
training appears to be on de-escalation-related knowledge, confidence to
manage aggression and de-escalation performance (although limited to
artificial training scenarios). No strong conclusions could be drawn
about the impact of training on assaults, injuries, containment and
organisational outcomes owing to the low quality of evidence and
conflicting results.ConclusionsIt is assumed that de-escalation techniques training will improve staff's
ability to de-escalate violent and aggressive behaviour and improve
safety in practice. There is currently limited evidence that this
training has these effects.
