Final month Aon, the most important advantages consulting agency, released a “study” claiming:
A major alternative to scale back healthcare prices for employers and improve general workforce well being by means of a complete weight problems administration program that features GLP-1 drugs.
This, in fact, is the other of what most researchers have proven. And within the immortal phrases of the nice philosophers Dire Straits: “Two males say they’re Jesus, considered one of them have to be incorrect.” We’ll shortly see who’s incorrect (um, that means about weight reduction medication) after we dive into the research in a minute. However first, let’s evaluation Aon’s earlier analyses.
A short historical past of Aon
Aon claimed that Accolade saved 8%, but it looks like they must coincidentally have been absent each on the day that the biostatistics professor defined how management teams work, and in addition on the day the fifth-grade math instructor defined how averages work.
Then, they claimed that Lyra – which is a psychological well being firm – achieved the next non-mental enhancements within the set of sufferers who had a minimum of one psychological well being encounter with considered one of their “220,000 high-quality suppliers”:
§ A 30% discount in non-mental health-related ER visits
§ A 30% discount in generic drug spending
§ A 20% discount in specialty drug spending
Thanks partly to beginning the y-axis at $4000 to enhance the optics, Aon additionally revealed that Lyra achieved a really excessive “effectivity ratio”:
I can’t object to that discovering as a result of – regardless of three many years on this area, about 100 articles/interviews/quotes/citations together with the Wall Street Journal, two trade-bestselling books and one Harvard Enterprise Faculty case study – I nonetheless don’t know what an “effectivity ratio” is, apart from that has nothing to do with evaluating contributors to non-participants in a psychological well being research. Apparently an “efficiency ratio” in healthcare measures how quickly a hospital turns over its stock. So Aon’s use of the time period recollects the immortal phrases of the nice thinker Bob Uecker: “Juuussst a bit outside.”
When publicly and privately requested to elucidate any of these items, Aon clammed up. That was possible smart on their half.
Nor will they reply right here, as a result of they perceive the Streisand Effect. (Barbara sued a photographer for photographing her Malibu mansion from the air as a routine a part of documenting erosion alongside the California shoreline on the behest of the state. Six individuals had downloaded that picture earlier than she sued. After she sued, one million individuals downloaded the picture. Additionally, she misplaced and needed to pay legal professional charges as effectively.)
Most just lately, it seems that they may have had their hand within the PBM cookie jar as effectively.
Aon’s Weight Loss Drug Research
Whereas admitting that prices bounce within the first yr, Aon discovered a 7% “bend” in the price curve within the second yr, by contributors as in comparison with a “exactly matched management group.” Matched controls, no matter how “precise,” are invalid, period. That’s the reason the FDA doesn’t let pharma corporations use them. Most famously, some Very Steady Geniuses within the wellness trade inadvertently proved this once they revealed this graph. They thought they had been displaying that contributors in wellness applications saved cash vs. matched non-participants. Sadly for them, a cursory have a look at the x-axis reveals the “whole financial savings” from the aptly named “remedy” began two years earlier than the remedy began, just because voluntary contributors are motivated.
The associated subject is that over a two-year interval – the identical period that Aon studied – most weight reduction drug customers have dropped out. But, there is no such thing as a accounting for – or mentioning of – dropouts on this research.
Solely individuals nonetheless on the medication are counted. The others can be “misplaced to follow-up.” Counting solely those nonetheless in this system on the finish is known as “survivor bias,” or the “final man standing” fallacy. It’s why any weight reduction program exhibits nice outcomes – most individuals give up most applications as a result of they aren’t succeeding. Paradoxically, the better the dropout charge, typically the higher the outcomes among the many few survivors.
It is usually fairly actually unimaginable for prices to “bend” 7% general by lowering the speed of coronary heart assaults and strokes by 44%. That’s as a result of there merely aren’t sufficient of those occasions to try this. The speed of each is about 1 per 1000 within the <65 insured inhabitants. And Aon didn’t even declare a 44% discount in these occasions. They claimed to scale back the “danger” of those occasions by 44%. A cynic may observe that clearly in the event that they did scale back precise occasions by that quantity, they might have stated so.

How they will decide somebody’s danger from their claims is anybody’s guess. Suppose twins have dad and mom who died early of coronary heart illness. The primary may be very involved about this. He takes statins, metformin, perhaps sees a heart specialist, will get a stent and so forth. The second does nothing to mitigate his genetic danger. The second is at a lot larger danger than the primary, however the “danger rating” will say the other. Many people don’t even know they’re in danger for coronary artery illness till they’ve an occasion. So how can Aon know?
What’s Aon as much as?
Certainly an actuarial consulting agency whose fame relies on, effectively, being an actuarial consulting agency wouldn’t danger that fame by writing articles like these, proper?
Effectively, actually not free of charge.
They bought paid by Lyra, bought paid by Accolade, and (allegedly) bought paid by Categorical Scripts. On this case – for anybody who doesn’t really feel like opening the free Weight Loss Drug Calculator above to determine themselves – Aon will “work with employers in modeling the long-term enterprise affect of GLP-1 adoption.”
And since their mannequin is incorrect, “working with” Aon is – as soon as once more within the immortal phrases of Dire Straits – “cash for nothing.”
