Watsi seems to be doing great work, but the title—"you helped save 33k lives"—reads as misleading to me. I guess "helped" could be doing a lot of heavy lifting here, but I would be incredibly surprised if the counterfactual number of lives saved was more than 3000. (But don't let this dissuade you from donating; concretely improving someone's life is totally a worthwhile goal, and Watsi seems very good at effecting this)

"Counterfactual number of lives saved" is not the normal sense of the phrase "save a life". By that logic, each person's life can only be saved once, which is not how people normally use the phrase.

Your definition may be useful for cold hard utilitarian calculus, of the sort that hospital directors need to do if they've run out of fundraising opportunities. However, "effective altruism" – which I suspect you're alluding to here – isn't actually an efficient way to save lives, the way it's usually practised (ignoring second-order effects, and everything that doesn't fit on a spreadsheet).

You're right; I should've been more precise. However, we have tools for dealing with this—that's what quality-adjusted life-years are for! I don't contest that surgeries often significantly increase QALYs, and may do so pretty cost-effectively.

Yes they are surprisingly cost-effective in the countries Watsi operates in, which isn't intuitive for those of us who live in places where surgeries are very expensive.

"A review across 23 LMICs found that low-complexity surgeries (e.g., appendectomy, hernia repair) cost only about ~$17 per DALY, whereas even complex procedures were often cost-effective" (Most surgeries on Watsi are low-complexity)

"Reports from the WHO and Lancet Commission consistently emphasize that investing in surgical capacity has high value, in many cases, more than essential drugs or vaccines on a per-DALY basis"

You must be fun at parties ;-)

Lol, I just care a lot about saving as many lives as I can; the most effective charities I've been able to find good evidence on save one life for $6–8k. If Watsi had a credible claim at being able to save lives 10x cheaper I would redirect my entire donation budget to them!

That said, once again, Watsi is great. I really appreciate all the hard work they've put into making this happen—this is orders of magnitude more impressive and impactful than most projects I've ever seen!

There was a link posted here that showed some hernia surgery in Malawi costing 400$ , some others listed via links at 160$ to 1000$.

I honestly have no idea about healthcare costs in countries like that, but assuming the main cost is a surgeon, the reported median salary for surgeons in Sweden is between 110-150k usd yearly. Assuming 200 working days a year and available for something like 4 surgeries a day on average that goes to about 137 usd per surgery. Adjust for Malawi being a far cheaper country but addition of more staff and a cost of 400$ for a relatively minor surgery doesn't seem too far fetched if there isn't middlemen taking a cut (actually googling it seems like middlemen can take a fairly large cut even with those costs).

Ah well then, please forgive my snark - you're right of course; I misread your intent with your original comment.
