ACKNOWLEDGEMENTIn preparation of the Clinical Risk Assessment & Management. A Practical Manualfor Mental Health Clinicians, we acknowledge and reference the New Zealand‘Assessment and Management of Risk to Others Trainee Workbook 2006’ and theStatewide Clinical Risk Assessment and Management Training ProgramParticipant Handbook.The authors would particularly like to acknowledge the work done by ProfessorChristopher Webster and colleagues in the development of the HCR-20.We acknowledge the contribution made by Dr David Chaplow, Director, MentalHealth in New Zealand along with Dr Sandy Simpson, Director of the RegionalPsychiatric Services in Auckland, New Zealand and their New Zealand colleagues.Also, many thanks to Mr Michael Davis, Mr Murray Ferguson, Mr Chi Meng Chu,Dr Andrew Carroll, Dr Daniel Riordan and Mrs Nicole Kitto.We would also like to thank our many colleagues within Justice Health, NSW andin particular the support of Ms Julie Babineau, Chief Executive, Professor KarinLines and Associate Professor John Basson.“We are not now and probably never will be in a position to be able to determinewith certainty who will or will not engage in a violent act. Relying on a range ofempirically supported risk factors, though, we can make a reasoned determinationof the extent to which those we are assessing share the factors that have beenfound in others to relate to an increased level of risk.” Mullen & Ogloff1iv

PREFACE"Risk: The nature, severity, imminence, frequency/duration and likelihood ofharm to self or others. A hazard that is to be identified measured and ultimately,prevented". (Best Practice in Managing Risk, document prepared for the NationalMental Health Risk Management Programme. June 2007).This definition comes from a document “Principles and evidence for best practicein the assessment and management of risk to self and others in mental healthservices. This was produced in the United Kingdom in 2007.In New South Wales, as in other states and countries with modern psychiatricservices, we are being asked about the risk that mentally ill people present tothemselves, their family members and other members of the public.We know that there is a real increased risk of serious harm to others by thementally ill, though it is small. The advent of increased use of illicit drugs has madethis a much more real issue.Assessing the risk, formulating a management plan, and carrying it into action willimprove patient care and from that position it will have a possible impact on futureharm.How is this assessment done? We know that most mental health clinician’sprediction of risky incidents by their patients is just above the level of chance. Whatwe are endeavoring to do is improve risk assessment and management. Severalactions are important:-Collecting as much information as is possible and analyzing it regardingfrequency, circumstances, severity of the risky behaviour.Speaking with family, friends, staff caring for the patient.Using actuarial tools that indicate the level of risk of the group which thepatient belongs.Putting all the information collected together and systematically examine itto assess the risk.Formulate a management plan.All of this should be done with careful, involvement of the patient, carers andstaff of mental health services.In saying all of this we must be clear that the responsibility for risk management isnot just the responsibility of individual practitioners. In the document from theDepartment of Health in London referred to at the start of this preface there is areference to their National Patient Safety agency and seven steps to patient safety.v

These are: Build a safety cultureLead and support your staffIntegrate your risk management activityPromote reportingInvolve and communicate with service users and the publicLearn from and share safety lessons, andImplement solutions to prevent harmRisk management is every member of staffs’ responsibility and all clinicians needto agree the strategy and method they will use to assess and manage clinical risk.This will need regular review and modification in the light of experience.It is important therefore to train staff in risk assessment and risk management.The manual that follows and the work done along with it is one such training. Weare grateful to colleagues in New Zealand, particularly for the work they have donein this area of mental health service development as we borrowed from them andwere encouraged. The work from the United Kingdom – England and Scotland hasalso encouraged us in our endeavour.In all of this work there is a need for the patient to be fully involved and the roleplayed by carers and staff respected. Culture and background are vital aspects ofour identities that must be taken into account. The emphasis of our New Zealandcolleagues on Maori culture reminds us that our Aboriginal patients have importantcultural beliefs which need to be integrated in any plan. Patients from a culturallyand linguistically diverse background equally need extra attention. Such mattersare part of our identity, sense of self so often challenged by mental illnessinstitution services.Leadership in all these matters is crucial and this training is to give practitioners theskills required for the task.A/Professor John BassonStatewide Clinical DirectorForensic Mental Healthvi
