Throughout the years, the effects of conflicts of interest with the sugar industry were never quantified, until a recent systematic review of systematic reviews was published in 2013 in the journal PLOS Medicine. The review found that in studies with a conflict of interest with the food industry, 83.3 percent found no evidence linking sugar-sweetened beverages with weight gain/obesity. In contrast, when only studies without conflicts of interest with the food industry were analyzed, the same percentage (83.3 percent) found a positive association—that sugar-sweetened beverages have a definitive connection with weight gain and obesity. This one study provides just a small glimpse of how much science has likely been affected by these types of influences. The Salt Fix: Why the Experts Got it All Wrong and How Eating More Might Save Your Life, Dr. James DiNicolantonio, June 2017Nothing particularly new, but we do need reminding of the importance of incentives even on hard-working, well-meaning, highly talented members of the medical profession. Of course, financial incentives can reinforce public health as well as degrade it. The Social Policy Bond concept, as applied to health, would align our national health goals with rewards to those who are efficient at achieving them. It's unfortunate that, under our current healthcare systems, there is little to encourage people to seek out those ways of improving our health at least cost. Medical specialists, expert in their field, advocate effectively for their share of limited resources, but the overall health of the nation isn't effectively targeted. Few people have any financial incentive to consider it, and especially not to question the current ways in which funding is allocated.
Health Bonds would be different. They would target our broad health goals, probably in the form of a range of indicators such as longevity and Quality Adjusted Life Years. For the bonds to be redeemed, each indicator would have to fall into a specified range, representing an improvement over the current level. Significant improvements in a nation's health will probably take decades to achieve, but Health Bonds would be tradeable, meaning that any coalition of interests who improve our health, however marginally, can profit from their doing so by virtue of the increased value of their bondholding. By backing and issuing Health Bonds, a government could effectively maximise the health gains per tax dollar spent without having to specify how such gains shall be achieved, nor who shall achieve them. Opportunities for the sort of corruption (whether deliberate or not) hinted at by Dr DiNicolantonio and the authors of the paper he cites, would disappear, to be replaced by a healthcare system in which the interests of practitioners and population would be entirely congruent.
