Background (for being here ?)
NICE guidance NG10, on the short term management of violence and aggression, recommends using an actuarial prediction instrument such as the BVC (Brøset Violence Checklist) or the DASA-IV (Dynamic Appraisal of Situational Aggression - Inpatient Version), rather than unstructured clinical judgement alone, to monitor and reduce incidents of violence and aggression and to help develop a risk management plan in inpatient psychiatric settings.

Center for Clinical Guidelines (DK)
Conclusions/recommandations: ü Standardised risk assessment tools can be
used to predict aggressive and violent behaviour
ü MHC staff should use the BVC in their clinical work in adult inpatient services

Growth of Risk Assessment
• Monahan (1981) – 5 studies • Early 1990s – handful of instruments • Today – too many instruments ?! • 1998 – first publication on BVC • 1999 – first publication on HCR-20 • Today
› 150+ disseminations on HCR-20 › Estimated 300 SPJ disseminations › Estimated 600 disseminations, generally
10
SPJ studies over time (Guy 2008)
11
SPJ Decision Steps (HCR-20 Version 3, Douglas et al., 2013)
1 • Gather relevant information
2 • Determine presence of risk factors
3 • Determine relevance of risk factors
4 • Develop formulation of violence risk
5 • Develop primary scenarios of violence
6 • Develop case management plans
7 • Develop final risk judgments

Brøset Violence Checklist - BVC
Ø A risk assessment tool hitting the Bull’s eye ?
13
Brøset Violence Checklist (BVC) History and Background
ü Developed at R.S.U. Bröset based on data from forensic inpatients.
ü Extensively tested out on acute wards, nursing homes and geriatric wards in Norway
ü Extensive validation studies in various settings nationwide as well as international
14
Brøset Violence Checklist
Six variables/behaviours: ® Confused ® Irritable ® Boisterous ® Physically threatening ® Verbally threatening ® Attacking objects
15
Interpretation and operationalisation • Confused - Appears obviously confused and disorientated. May be
unaware of time, place or person. • Irritable - Easily annoyed or angered. Unable to tolerate the
presence of others. • Boisterous - Behaviour is overtly "loud" or noisy. For example
slams doors, shouts out when talking etc. • Physically threatening - Where there is a definite intent to
physically threaten another person. For example the taking of an aggressive stance; the grabbing of another persons clothing; the raising of an arm, leg, making of a fist or modelling of a head-butt directed at another.
16
Interpretation and operationalisation
• Verbally threatening - A verbal outburst which is more than just a raised voice; and where there is a definite intent to intimidate or threaten another person. For example verbal attacks, abuse, name-calling, verbally neutral comments uttered in a snarling aggressive manner.
• Attacking objects - An attack directed at an object and not an individual. For example the indiscriminate throwing of an object; banging or smashing windows; kicking, banging or head-butting an object; or the smashing of furniture.

Interpretation of BVC score
Score Risk
Sum = 0 Risk of violence is small
Sum = 1-2 The risk of violence is moderate, Preventative measures should be taken
Sum = > 2 The risk of violence is high. Preventative measures should be taken and plans about how to manage an attack made.

Nurses and research…………. Professor C. Pirquet (Vienna 1927):
”one cannot think of nurses doing scientific research – their ability to think originally are more seldom than in men”
Chief medical officer Wyller (Oslo 1918):
”The knowledge that are forced into the nurses is completely dead ballast – their brain is not capable of receiving it”

Acceptability and psychometric properties of Brøset Violence Checklist in psychiatric care settings in China; X . Yao et al in Journal of Psychiatric and Mental Health Nursing, 2014
BVC provides nurses with a quick and easily administered method to screening out patients with violence potential, thus allowing for early intervention. Feedback from the nurses was quite encouraging and the further use of BVC seems promising.

Evidence on effects • Abderhalden et al in BJP (2008): Introducing twice daily
staff measures on risk assessment (BVC Swiss version) – 41 % reduction in severe violent incidents – 27 % reduction in the use of coercive measures
• Van de Sande et al in BPJ (2011): Implementing regular risk and violence assessment – 68 % reduction of aggressive incidents – 45 % reduction of time in seclusion
• Hvidhjelm et al in PhD thesis, Uni of Copenhagen (2015) – 48 % reduction in violent incidents

Nurses assessment of the BVC
ü 95,8 % thinks that the use of BVC rarely or never increase the use of coercive measures
ü 75 % describes increased insight in to the pt’s risk for violence, but not necessarily more insight in to pt’s vulnerability
ü 83,4 % reports that BVC is used activily in the daily risk assessment routines
ü 68,5 % reports that BVC makes them better in risk prediction ü 67,6 % reports that the use of BVC often or always leads to early
inteventions
