## Excess costs of for-profit healthcare ecosystem must be attributable to e-cigarettes

[UCSF🟥](wiki/pr-studies) paper projects additional health costs from exclusive e-cigarettes use at $2000.
It relies on sidelining the previous smoking history, and subfuscating the calculation
priors. The study was contracted by the FDA, which is currently in the process of
rejecting non-Big-Tobacco and non-smoking-relapse-flavored vaping products. Naturally
a press release embargo was used to avert the usual academic review manners; blatant
conflicts of interest found no mention, yet teared-into papers did (obligatory [Glantz](/wiki/Glantz),
who coincidentally also engineered the grant).

Not gonna do a full review here, as it doesn't appear to be a classic PR study.
It was largely just crosspolinated [<1>](https://12ft.io/proxy?q=https://www.ketv.com/article/study-vaping-costs-per-year/40082883)
[<2>](https://www.sfgate.com/news/article/New-study-finds-costs-of-vaping-exceeds-2-000-17193509.php)
among syndicated cable outlets. Unlikely to sway the public at large (already pretty
smothered with trivia exaggerations); nor will this add significantly to smokers
being deterred from quit attempts.

#### calculation selectives

The final calculation, of $2024 for ex-smokers now using e-cigarettes exclusively,
actually doesn't seem too farfetched. And probably reproducible from the amassed
NHIS data. Which doesn't seem too high; given the US healthcare ecosystem quite benign
even. The FDA is probably more interested in the total $1.3 or $15.1 billion numbers
to rationalize the PMTA clownshow.

Naturally it relies on misrepresenting the previous smoking history. People using
e-cigarettes have often given up on other quitting aids, and not uncommonly
already experienced health impacts from decades-long cumbustible use. The paper
makes quite a few attempts at obfuscating it. Extrapolating from 0.2% prevalence
(an unlikely quota to begin with) seems ventured. Interestingly the comparison
to the $61.6 billion costs attributed to current smokers falls short. Given
their interpretative approach, the PR could have pointed out the $40 billion
loss in healthcare profits due to smokers becoming ex-smokers.

Not gonna delve deeper into this. Because hey, if the authors had welcomed
a full review, they could have not averted the usual review processes.

   gives a rundown of the interpolation on a small sample size and
   misrepresenting discrepancies to the actual default cost of continued
   smoking.

#### author response

Did send the corresponing author an email. No reply. In retrospect, asking for
potential COI self-evaluation wasn't overly courteous, TBH.

#### verdict

Nothing wrong with assessment papers, even if was just a numb causality
chain.  Obviously "how can things be improved?" studies have more practical
value.  But it's kinda obvious what this paper was construed for.  Judging
on the meta attributes (COI), it warrants a "False"; but for lack of
calculation review leaving it at Mostly here.

  "text": "Aims This study estimated annual healthcare expenditures attributable to current e-cigarette use among US adults, including current exclusive and dual/poly e-cigarette use.\n\nMethods Analysing the 2015\u20132018 National Health Interview Survey data, we estimated the impacts of e-cigarette use on healthcare utilisation among adults aged 18+ years. Healthcare utilisation outcomes were hospital nights, emergency room (ER) visits, doctor visits and home visits. Current e-cigarette use was categorised as exclusive and dual/poly e-cigarette use. The econometric model included two equations: health status as a function of e-cigarette use and other independent variables, and healthcare utilisation as a function of health status, e-cigarette use, and other independent variables. Using an \u2018excess utilisation\u2019 approach, we multiplied the e-cigarette-attributable fraction derived from the model by annual health expenditures to calculate healthcare expenditures attributable to current exclusive and dual/poly e-cigarette use, the sum of which were expenditures attributable to all current e-cigarette use.\n\nResults Current exclusive and dual/poly e-cigarette use, with 0.2% and 3.5% prevalence in 2015\u20132018, were associated with higher odds of reporting poor health status than never tobacco users. Poor health status was associated with higher odds of using the four healthcare services and a greater number of ER and doctor visits. Annual healthcare expenditures attributable to all current e-cigarette use was $15.1\u2009billion ($2024 per user) in 2018, including $1.3\u2009billion attributable to exclusive e-cigarette use ($1796 per user) and $13.8\u2009billion attributable to dual/poly e-cigarette use ($2050 per user).\n\nConclusion Adult current e-cigarette use was associated with substantial excess healthcare utilisation and expenditures.\n\nNot applicable. We used secondary data that are publicly available for our analysis.",
