9 9 How can the cost of suicide be measured?

10 Components of the cost of suicide Direct costs (medical, funeral, legal, etc.) Indirect costs ( human capital approach) lost tmarket ktoutput t lost non market output Non economic, quality of life cost to individual ( willingness to pay ) py) Cost to family and associatess decreased productivity decreased quality of life Increased risk of health problems and suicide Societal costs lost productive capacity perceptions of family and community cohesiveness suicide contagion costs to prevent suicidal behavior 10

17 17 Effects of suicide on the family [Diversity of methods and target subjec cts makes it difficult to draw clear conclusions] Response of family members to suicide varies highly based on relationships of deceased within the family, the underlying psychological health of surviving family members, and type of response from external support networks Common issues that need to be dealt with are blame, shame, secrecy, stigma Decreased family cohesion and adaptability following suicide can lead to separation, mental health problem ms, problems with the law, and suicide Social ostracism and self isolation of family members is common Estimated 7,000 12,000 children lose a parent to suicide each year in US Cross sectional studies find increased substance abuse, violence, suicide attempts Unclear if response to suicide is fundamentally different from other types of bereavement in children Very few studies on effect on family members following attempted suicide Very few studies on family effect of suicide in low and middle income (LAMIC) countries ti but we do know from stu udies of HIV/AIDS that t children from LAMIC who lose a parent have poor educational, health and social outcomes

19 19 Serious methodolog gical problems in assessing the costs associated with suicide The human capital approach yields low or negative values for certain groups and implies life is worth more in richer countries How do you value lost non market output? Willingness to pay methods assess the human value of life as the amount a person would be willing to pay to avoid death, butdifferent assumptions when using the method lead to widely variant results about the value of life ($0.1 million to $29.4 million), and it has never be assessed for suicide Is the quality of the life of someon e who dies of suicide the same as that of someone who dies of some other cause? Should the fact that most persons who die of suicide have mental illness and, thus, are less productive and have highermedicalcosts costs infuture beconsidered? The lost output and decreased quality of life of family members and associates or suicide decedents and the negative utilities on society more generally are not considered in any of the costing mo odels How should the social costs of suicide prevention activities be factored in?

27 27 The pesticidee story Worldwide intentional pesticide ingestion is the most common method of suicide accounting for over 300,000 suicides annually. In China pesticides are used in 62% of all suicides. The estimated 166,000 suicides by pesticide ingestion each year in China account for one fifth of all suicides in the world. 75% use pesticides stored in the home 58% use category I organophosphates 62% receive medical resuscitation that fails Pesticides are also used in 574,000 of the medically treated attempted suicides in China each year, 28.7% of all attempts. 84% use pesticid des stored in the home 82% use category I organophosphates

33 Promoting the suicide prevention effort in LAMICs Develop model research and service delivery centers around the country (centers of excellence) Develop, implement and monitor local and national suicide prevention plan Conduct periodically national psychological autopsy studies to monitor the changing pattern of suicide iid and attempted t suicide iid Conduct high quality research to assess the cost effectiveness of proposed prevention measures

34 Promote national and local suicide prevention plans with the follow wing goals: 1. Promote psychological well being, resilience and community connectedness 2. Promote broad based support for suicide prevention 3. Decrease access to and lethality of means for suicide, particularly pesticides 4. Enhance social supportnetw works for high riskgroups groups 5. Promote community based screening programs to identify high risk individuals 6. Change attitudes about me ental health problems and suicide 7. Improve availability and quality of mental health services 8. Develop specific services for high risk individuals and others affected by suicide iid 9. Expand scientific evidence base for the prevention and management of suicide 10. Improve and expand surveillance of suicidal behavior 11. Develop sources of sustained funding for suicide related services and research 34

35 Prevention measu res that need to be tested as part of lo ocal and national suicide prevention n plans 1) different methods for restricting access to means 2) methods for increasing psychological resilience in youth 3) methods to increase social support networks for high risk groups 4) promotion campaigns about mental health and suicide 5) improve health providers ability to recognize and manage the psychiatric problems associated with suicide 6) institutescreening screening program ms to identify high riskindividuals individuals 7) expand crisis support services and targeted mental health services for high risk individuals 8) increase the ability of primary care facilities to manage the medical complications of suicide attempts
