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 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 good philosophers Dire Straits: “Two males say they’re Jesus, one in all them have to be flawed.” We’ll shortly see who’s flawed (um, that means about weight reduction medicine) after we dive into the examine in a minute. However first, let’s evaluate 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 trainer 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 at the least one psychological well being encounter with one in all 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 partially 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 a long time on this subject, 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 examine. Apparently an “efficiency ratio” in healthcare measures how quickly a hospital turns over its stock. So Aon’s use of the time period remembers the immortal phrases of the good thinker Bob Uecker: “Juuussst a bit outside.”
When publicly and privately requested to elucidate any of this stuff, Aon clammed up. That was probably clever on their half.
Nor will they reply right here, as a result of they perceive the Streisand Effect. (Barbra 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 folks had downloaded that picture earlier than she sued. After she sued, one million folks downloaded the picture. Additionally, she misplaced and needed to pay lawyer charges as properly.)
Most just lately, it seems that they may have had their hand within the PBM cookie jar as properly.
Aon’s Weight Loss Drug Research
Whereas admitting that prices bounce within the first yr, Aon discovered a 7% “bend” in the associated fee 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 firms use them. Most famously, some Very Steady Geniuses within the wellness business inadvertently proved this after they printed this graph. They thought they had been displaying that contributors in wellness applications saved cash vs. matched non-participants. Sadly for them, a cursory take a look at the x-axis reveals the “complete financial savings” from the aptly named “therapy” began two years earlier than the therapy began, just because voluntary contributors are motivated.
The associated difficulty is that over a two-year interval – the identical period that Aon studied – most weight reduction drug customers have dropped out. But, there isn’t any accounting for – or mentioning of – dropouts on this examine.
Solely folks nonetheless on the medicine 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 reveals nice outcomes – most individuals give up most applications as a result of they aren’t succeeding. Satirically, the larger the dropout price, typically the higher the outcomes among the many few survivors.
It’s also fairly actually inconceivable for prices to “bend” 7% general by decreasing 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 do 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 “threat” of those occasions by 44%. A cynic may observe that clearly in the event that they did cut back precise occasions by that quantity, they might have mentioned so.

How they will decide somebody’s threat from their claims is anybody’s guess. Suppose twins have dad and mom who died early of coronary heart illness. The primary could 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 threat. The second is at a lot greater threat than the primary, however the “threat 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, properly, being an actuarial consulting agency wouldn’t threat that fame by writing articles like these, proper?
Properly, actually not without spending a dime.
They received paid by Lyra, received paid by Accolade, and (allegedly) received 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 impression of GLP-1 adoption.”
And since their mannequin is flawed, “working with” Aon is – as soon as once more within the immortal phrases of Dire Straits – “cash for nothing.”
