Re: Can suicide be prevented?

Dear Madam

Is Kamerow as guilty of lacking specificity and focus as the United States (US) Surgeon General he criticises (1)? "Psychiatric disorders" may be present in around 90% of people who kill themselves, but what does this actually mean?

Meta-analysis of North American psychological autopsies shows that substance misuse, present in 40%, predominates (2). However, this includes "harmful use" of substances, including binge drinking, and even simple alcohol intoxication; no sensible person would consider these phenomena psychiatric disorders.

Mental illness, such as depressive disorder (34%) and schizophrenia (4%), is represented (2), but even these figures warrant closer observation. As depressive disorder is hugely overdiagnosed in life (3), what is there to suggest the same is not true in death? Recent prescription of antidepressants to a deceased subject or retrospective reports of insomnia, lethargy and low mood from family members do not automatically equate to a true diagnosis of depressive disorder. Yet the pragmatic methodology of psychological autopsy studies dictates precisely that.

The reality is that a small minority of people who commit suicide are mentally ill. The vast majority are people encountering difficult life circumstances, to whom suicide seems a logical solution at the time; acts are often carried out impulsively and whilst intoxicated. This is borne out by the close relationship between suicide rates over the last century and international economic trends, exemplified by the recent increase in the US during the current recession (4).

We must not be complacent in the management of people who are indeed unwell, but any suicide-reduction policy targeting psychiatric or primary care services is bound to fail, as has been seen in the US. Successful policies in the United Kingdom, such as restriction of analgesic sales, have restricted access to means.

The US national suicide rate will not dramatically reduce until radical gun law is introduced. Kamerow may be waiting some time.

I remain, Madam, your obedient servant,
