Hospital Algorithms Are Biased Against Black Patients, New Research Shows (medium.com) 79

Algorithms meant to help patients in need of extra medical care are more likely to recommend relatively healthy white patients over sicker black patients, according to new research set to be published in the journal Science. From a report: While the researchers studied one specific algorithm in use at Brigham and Women's Hospital in Boston, they say their audit found that all algorithms of this kind being sold to hospitals function the same way. It's a problem that affects up to 200 million patients being sorted through this system, their paper claims. Sendhil Mullainathan, co-author of the paper and professor at the University of Chicago, says the research is intended to empower "customers" -- hospitals in this case -- to vet the mechanisms behind the software they're buying. "We're going through this phase where customers buying crucial products aren't being informed in what they are," Mullainathan says. "It's like when I buy a car -- I don't literally know what's happening under the hood."

    Can you stop screaming at me please? NORMAL TONES OF VOICE ARE RACIST!

    Hospitals try to come up with a care regimen based on a proverbial "average" patient.

    That doesn't mean they don't deal with patients as individuals.

    Merely that their care metrics START at a given point, then are adjusted to meet the patient's needs.

    It's not like they get a POC in, and the nursing staff berate them for not responding "as well as a WHITE patient does".

      No one said anything about racism, that's all you. Algorithms can't be racist but they can be wrong or misleading, and when that happens systematically like this it can be a problem and it can also be interesting to learn why.

    The algorithms aren't biased toward white people. They are biased toward conditions and insurance coverage which generates more revenue. This apparently indirectly results in recommending more attention for white patients than black patients as a statistical correction but has nothing to do with racial thinking or bias. The software is not looking at race, if more black patients came in with better insurance or more profitable conditions the software would show a different correlation.

    The race card is a red herring to divide us roughly down the middle and pit us against each other. The actually issue is one of wealth inequality which divides us at 99.99% to 0.01% distracting you from that is the purpose "multiple dimension" racial thinking. The straw man is when they "sicker black people." It shouldn't matter what race the individuals are that has nothing to do with medical care but the sicker part does. Are you good with a for profit medical system that would put assign more resources to a nose job than your heart attack? If not stop supporting the idea the system should work that way, regardless of race.

    • Pretty sure that's the point, and I'm pretty sure the goal here is to maximize patient outcome, not profit.

Those aren't better outcomes but they are certainly more profitable.

If the report stuck to discussion of income it would probably not have provoked this this reaction in you. In the report, 'black' is used as a proxy for poorer. But it is right; since black people are poorer and hence pay less for their healthcare they get recommended for less treatment in the future.

        The algorithm calculates a threshold based on prior expenditures and asks doctors to pay more attention to people who are above the threshold. The study actually says that Doctors are biased _for_ black people. Doctors countermand the algorithm and admit/accept black patients at a much higher rate (19.2% vs. 11.9% in sample), and higher than the trained/computed factor of 18.3%. The study does further sift the data for the most critical patients and says that doctors could do better there.

    When you read the actual article it turns out that the algorithm isn't biased against black people, it selects people who have more healthcare expenses. It turns out that black people spend less on healthcare, and so their cases don't receive the same weighting. The article is very careful to avoid providing enough detail for us to see how it all really works because that would probably make it clear that the problem wasn't the algorithm, but rather s conflict between the researcher's desired outcomes and the actual outcomes. The algorithm is designed to steer patients with the highest need of medical attention over and above the "usual" level of care, and the article does nothing to suggest that the algorithm is not correctly identifying these patients. The number of people with chronic heart disease is not the same number of people who need extra care over and above the usual care for people with chronic heart disease, but the researcher and the author of the article conflate the two in their hunt for victimhood.
    • The algorithm is based on assumptions that bias the results in favor of white people. It needs to bias results on better patient outcomes.

        It does bias results based on better patient outcomes, the algorithm simply decided that there are real divides between certain groups of people and then the "journalist" inserted their own biased thinking into the article.

        It's not racist, because it doesn't exclude ALL black people or ONLY includes white people. It divides across a line which happens to have more black people on one side compared to the other. Moreover, it happens to be that the people recommended by the algorithm get MORE intensive treatment which statistics prove that groups that receive more treatment also have higher deaths both as a result of the cases they came in as well as higher risk of hospital-borne diseases.

        We inserted the bias into the statistical result, the 'algorithm' is just a simple statistical binning algorithm, you can't call the algorithm or its creators racist because they happen to show results that don't stroke your ego or accord to your political viewpoint.

      • Agree completely. One of the authors of the paper (who is quoted in the article) is simply pointing out that using ineffective proxies can result in poor patient outcomes. In this case, the proxy should be adjusted to result in better patient outcomes. The conclusion would be the same even if you leave out the dimension of race.

    From the comments [sciencemag.org] on the original article: [sciencemag.org]

    "When the researchers searched for the source of the scores, they discovered that Impact Pro was using bills and insurance payouts as a proxy for a person’s overall health—a common tactic in both academic and commercial health algorithms..."

    Seems to me the algorithm is design to maximize profit rather than health outcomes, or at the very least the designers are being lazy/clueless in selecting parameters that describe the patient's state. African Americans get ignored because they are less profitable:

    "The problem with that, he notes, is that health care costs tend to be lower for black patients, regardless of their actual wellbeing. Compared with white patients, many black patients live farther from their hospitals, for example, making it harder to go regularly. They also tend to have less flexible job schedules and more child care responsibilities."

    The same should apply to any low income patient regardless of skin color. So the algorithm is not exactly racist. It is just greedy, stupid and inhumane like the rest of the healthcare system in US.

    • Agree - the algorithm is about costs, reasons about prior costs, and makes recommendations. It's up to the nurses and doctors to do their job. But what the study leaves out is that, regardless of income, women spend more on health care than men. But you can't report that an algorithm is biased against men, so they left out those conclusions.

      Nonsense. The algorithm attempted to make a high level recommendation based on the data which is available. Thank HIPAA for keeping most healthcare related data out of sight. That, plus the fact that medical records are notoriously difficult to parse and understand, it was a reasonable decision to use total previous cost as a proxy for how sick the patient has been in the past (billing records are much more standardized than medical records).
