Suicide statistics could benefit from a different analysis

Regular readers of this blog would be aware that I feel that the prevention of suicide gains less attention than early intervention and that mental health has dominated suicide discussions to the point that suicides without a mental health context are largely ignored. This situation is starting to change with non-psychological pressures gaining some acknowledgement, if not examination. Mental health still dominates but the pool of contributory factors is expanding.

On 30 November 2020, the Medical Journal of Australia published the best recent example of this change, an article called “Suicide by young Australians, 2006-20415: a cross-sectional analysis of national coronial data.” The most useful statement in the research report, and the media release, is:

Noisy Buggers in the Post-COVID world

Guest Post by Melody Kemp

In my more bizarre moments, I can imagine the cockpit conversation:

‘Hey Bill, there’s the blue and white house. We turn left here’
‘Bob, Copy. Over.’

Of course, it’s nonsense to think that the complexities of aircraft take-offs and landings would depend on visual cues, rather than complex technology, weather and fuel economy.  In fact, it’s the very technology that allows communities to track and identify aircraft and the noise level as they pass overhead.

But I have to admit that, particularly at night, when I see the queue of aircraft waiting to approach, their starboard and port lights blazing into our living room, it’s hard not to go out and shake an impotent fist at the crew.

As I completed this third paragraph, a Jetstar plane flew overhead. I measured the roar at 76DbA, another app told me it was slightly less than 1000 feet above my roof.  As it continues to descend, it passes over the densely populated parts of the city that follow the Brisbane River, including New Farm and Doomben, well known to race goers. What was that old saying about don’t scare the horses?

I work at home. My concentration and the paragraphs I write, come in lumps divided by the passing of planes. Some, like the Flying Doctor prop-jets, make, in objective terms, little noise (around 58dBA), but if one is sensitised to the noise in general, they become yet another psychological hazard. Evidence for aircraft noise exposure being linked to poorer well-being, lower quality of life, and psychological ill health is reflected by the responses to my questions and Facebook comments posted by concerned residents (some are included below)

The never-ending line between healthy and sick

Infographics are increasingly used to summarise sometimes quite complex reports about occupational health and safety (OHS) matters. But often the nuance of the facts being depicted are stripped away in the translation process. There is one graphic that is repeatedly used in the context of mental health that seems to misrepresent reality for the sake of clarity.

Thanks, but we need more

Statistics are vital to any decisions about occupational health and safety (OHS). Safe Work Australia (SWA) does a great job providing statistical packages based on the data sources it can access. Last week SWA released its 2019 report on “Work-related Traumatic Injury Fatalities” which identified vehicle collisions as, by and large, the most common cause of worker fatalities. This category may be a surprise to many readers but perhaps the most important part of the report is what is omitted.

The black sheep of safety leadership

Western Australia’s Industrial Manslaughter (IM) laws are now in effect. The same arguments for and against were posed in Parliament and outside as they were in Queensland and Victoria, and the Australian Capital Territory well before that. The IM laws will face the same institutional hurdles to application and offer the same, nominal, deterrent effect.

But WA also prohibited insurance policies that cover the financial penalties applied by the Courts. Such policies may make good business sense in managing risk, but they also remove the pain and deterrence intended in the design and application of Work Health and Safety laws.

Evidence of COVID19 anxiety AND optimism

One of the first research reports into the psychological impacts of the COVID19 pandemic has been published in the Medical Journal of Australia.  It studied the first month of the infection’s appearance in Australia and seems much more evidential than some of the marketing-based survey reports that have also appeared in the last three months.  Below is a reformatted summary of findings from the report’s Abstract:

  • “The estimated prevalence of clinically significant symptoms of depression was 27.6% and
  • of clinically significant symptoms of anxiety 21.0%
  • 14.6% of respondents reported thoughts of being better off dead or self-harm on at least some days and
  • 59.2% that they were more irritable.
  • An estimated 28.3% of respondents reported great optimism about the future.”

The structure of this study was limited to a specific timeframe – April 3-May 3 2020 – so it is no surprise that most of the respondents who had contracted COVID19 were from New South Wales which had outbreaks from the Ruby Princess cruise ship and several aged care facilities prior to the survey period.

Concussed sportspeople are workers too

David Michaels devoted a whole chapter to sport-related concussions and brain damage in his 2020 book “The Triumph of Doubt“. He wrote about how the National Football League obfuscated over the appearance of concussions and chronic traumatic encephalopathy, and how the the NFL downplayed the injury’s significance by referring to repeated head trauma as Mild Trauma Brain Injury.

The Australian experience is different and this was examined recently in an excellent edition of the ABC radio program, The Ticket. Significantly several interviewees mentioned the injuries in relation to occupational health and safety (OHS) and workers compensation.
