Relative risk

<<< Back to Misc

Hi Antoinette

Good to hear from you as always.

I must admit it's been encouraging to see my work gain increasing recognition. I'd like to think that it's robust. The NZ Parliamentary Health Select Committee accepted it without question; no one has been able to discredit it though some have tried using the, "but the benefit of medicines are so significant that the adverse effects are acceptable" argument.

I'm attaching five slides.

The Relative risk - meteor one is NZ data with some gaps filled with overseas data (mainly related to food as the is no definitive NZ data available and officials generally accept Aus/US data as being generally similar to what can be expected in NZ. The main references are included -- I data mined every government, quasi government, sport foundation, university, and every other data source I could think of. I also corresponded with researchers around the world who have studied medical injury in hospitals. None of them could recall coming across any injury caused by supplements which means that they exist at the background noise level.

The relative risks - bubble graph is the same data stripped to several common causes of fatality represented with bubbles proportionate to risk. Note that one axis is deaths per million at risk and the other is deaths per million total total population. I'm working towards developing a graduated range of risks for individual risk and for societal risk for use in the regulation of supplements. The biggest problem I see is that regulators talk in terms of 'acceptable level of risk' but they never define it or even attempt to -- they apply the old-boy 'we know best' method which is incompatible with an evidence based era, and with good regulatory practice. The model is in draft form in 'amodel for prioritising risk management policy and resources.'

The 'relative risk - Boeing 747' attachment is using Canadian data -- and includes risk groupings on the left margins.

The Canadian Minister has acknowledged that in Canada it costs $Can 10 billion (yes billion) to deal with adverse effects of pharmaceutical drugs alone!! And the cost of the actual drugs to the Canadian government is about $Can 15 billion. In other words, for every dollar spent on drugs, another (acknowledged) 66 cents is spent managing the adverse effects of them.

The fifth slide is one by professor Lucian Leape (Harvard University) who's adapted work by a French Aviations professor Renee Amalberti. It demonstrates how dangerous modern medicine is compared to many other activities. The mountain climbing relates to high altitude climbing such as Mt Everest (30% of all successful climbers of Mt Everest are dead as a result of climbing activities!)

If you need to mention, I was a member of the NZ government's expert group advising the government on the reporting and management of medical injury in our health system.

I'm undertaking a similar exercise for the UK & USA -- preliminary data for both suggest similar patterns. Given the global nature of both medicine and food supplements, I'll be very surprised if there is any significant variation in results. Certainly regarding medical injury in hospital research, that coming out of NZ, Australia, US, UK, Denmark, France all point to an adverse event rate of about 10% with about 1:300 of all admitted to hospital dying from a highly preventable medical injury.

Oh to be able to present all of this at Codex! Set acceptable levels of risk and the argument becomes academic... it will then shift from philosophical to evidence based. Perhaps you'd like to submit a discussion paper to codex?

Kind regards
