Is it time for AI to start replacing doctors?


Hello wizards and apprentices,

Most people, regardless of their politics, understand that healthcare, notably in the US, is too often unaffordable and sometimes destructive through financial means.

Many doctors, from my observations, function as pen pushers in what seems an administrative bureaucracy, relying as often as not, on remembered-information rather than improvisation or critical thinking. Many of the conditions they treat or medicate are done so in an almost automated manner. In many cases, a nurse would suffice at a much lower cost.

Obviously those who sacrifice a decade of their lives to study medicine desire and deserve to be rewarded. The discretion and experience that comes with such an immersive decade is of undeniably great value. However, I am convinced AI could rival a significant portion of what they do, theoretically at a drastically lower cost.

We (or some of we) trust AI to pilot vehicles, some of them weighing 80,000 lbs. We (some of we) trust AI with many serious matters; it could be argued that it has already begun replacing professionals at the PhD level, eg psychologists (Fusion Centers, law enforcement, pre-crime, etc). There's social credit and Trust Scores and more. Clearly we (some of we) are willing, if not eager to shirk our burdens and responsibilities onto artificial shoulders. Why not include, at least one, application that might have a clear, unambiguous and tangible benefit to the majority?

I think the Hippocratic oath is very amenable in this direction.

In The Checklist Manifesto, Atul Gawande wrote that he

...came across two professors who studied the science of complexity, which highlighted three types of problems in the world: the simple, the complicated and the complex. They are defined as:

Simple Problems – “are ones like baking a cake from a mix. There is a recipe. Sometimes there are a few basic techniques to learn. But once these are mastered, following the recipe brings a high likelihood of success.”

Complicated Problems – “are the ones like sending a rocket to the moon. They can sometimes be broken down into a series of simple problems. But there is no straightforward recipe. Success frequently requires multiple people, often multiple teams and specialized expertise. Unanticipated difficulties are frequent. Timing and coordination become serious concerns.”

Complex Problems – “are ones like raising a child. Once you learn how to send a rocket to the moon, you can repeat the process with other rockets and perfect it. One rocket is like another rocket. But not so with raising a child. Every child is unique. Although raising one child may provide experience, it does not guarantee success with the next child. Expertise is valuable but most certainly not sufficient. Indeed, the next child may require an entirely different approach from the previous one. And this brings up another feature of complex problems: their outcomes remain highly uncertain. Yet we all know that it is possible to raise a child well.”

For the longest time medicine has been part of the complex problem set. Doctors (very rightly) are highly trained with a minimum of 4 years of training followed by years of residency. The profession is seen as highly complex where they need to combine their book learning, with hands-on training and decades of experience to diagnose and treat a wide variety of health conditions. However in Low and Middle Income Countries, where doctors are in short supply, can some level of healthcare be provide by applying Artificial Intelligence to the SOAP (Subjective, Objective, Assessment, Plan) Note along with a touch of the Bayesian Priors?

I think most people can relate to the horrible experience of calling in to a bank or insurance company and being forced through their chatbot voice recognition system instead of getting to talk to a real person.

If we can't even do something that simple (granted I understand the goal with chatbots is to prevent people from reaching a human rather than actually helping them) how could we possibly believe that an "AI" doctor is a good idea? Find a simple to moderate complexity consumer interaction that AI does well, and maybe we can begin to think about how it could help on healthcare. For now, it will only lead to the hellscape we see in other areas of customer service

Let’s say starting tomorrow we decided to pay all doctors in the US $0 dollars a year. How much would the US actually save an annual healthcare expenditures? Approximately 8%

Doctors salaries are not a major driver of healthcare expenditures - they’re just an easy target because doctors tend to be the most public facing part of healthcare. How many health care administrators do you meet when you go to the hospital?

This contempt towards doctors never fails to impress me... I don't see it aimed at other professions either.

Check expert systems, there were already experimental good medical experts systems in the 1980'. None of them ever hit the market, because medicine is an incredibly difficult market to penetrate due to regulations, but also the structure of power: When doctors can vet what they buy or use, nothing that they perceive to weaken their power can succeed.

One area you can try is alternative medicine, such as naturopathic medicine, which is a social group much less powerful.

U.S. jurisdictions that permit access to prescription drugs to naturopathic medicine: Arizona, California, District of Columbia, Hawaii, Kansas, Maine, Montana, New Hampshire, Oregon, Utah, Vermont, and Washington.

This post is extremely stupid, reeks of ignorant arrogance. And one like it seems to pop up every month.

Why don't we ever folks like this ever ask, "when will AI replace SWE?"

Afterall SWEs deal with deterministic systems that follow well-understood laws of physics, while doctors deal with humans with all their capricious complexities. By any logical thought, software engineering is orders of magnitude more replaceable by AI than doctors, yet the people writingb these posts don't ever consider themselves threatened to be replaced by AI. Arrogant ignorance.


👤 nradov
Your "observations" are ignorant, condescending bullshit and thus the entire premise of your question is wrong. Go spend a few years working with physicians in an actual healthcare delivery organization and you'll understand how it really works.

AI can be somewhat helpful in medical research and clinical decision support. But compared to simpler deterministic algorithms it is a marginal improvement at best. In particular AI sucks at gathering actionable clinical data from patients.

The US is an outlier. There are countries with a similar and a much higher GDP/per capita that pay almost 50% less.

I’m a programmer, and my dads a doctor, and for ten years I’d always tell him that something like 20 questions could do his job.

After about 5 years he did this graduation speech and in it he referenced that: “yes, AI is getting great, your phone is a supercomputer, but the truth is that a computer will never be able to hold the hand of a dying patient and tell them it will be all be okay.”


👤 bediger4000
I think AI already has supplemented doctors. Think about all those prepandemic articles about how early/bad the flu season was based on number of Google queries on "flu symptoms".

And be honest: you've googled some set of symptoms to see what you've got, probably before deciding to see a human doctor. No, you don't have 5-alpha reductase deficiency.

You say that doctors are pen pushers in administrative bureaucracies and come to the conclusion that doctors need fixing and not the bureaucracies?

That seems like a very odd and backwards conclusion which reeks of treating a symptom instead of the root cause. I think you may have missed the forest for the trees.

The SOAP note (an acronym for subjective, objective, assessment, and plan)is a methodology for documenting a patient's condition on first examination by a medical professional. It serves as an excellent cognitive framework for medical professional to assess their patients.

The SOAP Note originated from the early work done by Dr. Lawrence Weed (an American physician, researcher, educator, entrepreneur and author, who is best known for creating the problem-oriented medical record as well as one of the first electronic health records).

SOAP notes are commonly found in Electronic Medical Records as a means to succinctly communicate patient information in a standard format and are particularly useful between hand-offs between medical professionals.

Modern Electronic Health Record (EHR) Systems offer a great deal more in terms of adding additional diagnostic information as well as a longitudinal patient record but the basics SOAP note could prove immensely valuable as we think about how to design a system that can empower Community Health Workers (CHWs).

SOAP Note in Practice (highly simplified for an illustrative example)

Situation: A medical professional encounters an individual who seeks or is identified for medical care

Subjective data collection

Shaking chills

Muscle ache

Fatigue

Objective data collection

Fever of 102 F (suing a Bluetooth connected thermometer or a cell phone camera based temperature detector)

Malaria Rapid Diagnostic Test (RDT) administered - shows positive

Assessment

The Subjective and Objective information is collated in the medical professionals mind and and she assesses that the patient shows indications of Malaria

Plan

Based on the Subjective and Objective and informed by the Assessment, the medical professional develops a Plan that is specific to the situational context - in this case it may involve sending the patient for a confirmatory Malaria confirmatory test or in some cases starting them directly on anti-malarial treatment.

The SOAP note allows a complicated problem to be broken down into components to then become a simple problem. However, in Global Health today, this complicated problem is treated as a complex problem because it is felt that only a doctor with decades of experience and a medical degree would be able to accurately diagnose and treat Malaria.

There any studies looking for differences in outcomes between patients cared for by physicians and those cared for by other highly intelligent, capable humans with fewer years of specialized training in healthcare.

It might be interesting to examine some of this literature in the context of this thread.


👤 sniperjoe360
I think it might happen in diagnostic specialties like pathology and radiology. But in situations in which "speaking to patients" is required - many of whom cannot write, much less use a computer, you need nothing short of AGI.

An if statement can replace doctors. But then insurers, hospitals, and drug companies would lose money.

👤 desmond373
Doctors have very complicated jobs.

They need to deal with patients expectations and understanding of their own diseases

Like self-driving, the 1 mistake AI made would be global headlines, people are still too biased

This is a profound misunderstanding of both healthcare and the current state of AI.

I doubt you'll ever find an insurance company willing to underwrite that risk

I’m a physician, medical oncologist and researcher with a previous background in software engineering. I happen to hear your points often and always reply the same way: if it is that easy and cost-saving, why don’t you build a tool that does this? The healthcare market is huge, the knowledge basis is more or less the same for all countries and almost all information is available online for free. There is a plethora of startups developing symptom checkers, supportive tools, clinical decision support systems and much more. I’m testing a lot of these systems and helping companies to realize their wishes, still in my opinion those systems are ages from what doctors are able to do. The argument has been made before, that physicians make up only a fraction of the total cost of healthcare. There is plenty of data supporting the fact that physicians even save money for healthcare systems and serve to avoid unnecessary, expensive and possibly harmful diagnostics. So if you are able to develop a tool that is competent enough to talk to you for 2 minutes, perform 20 secs of auscultation and correctly diagnose and treat your common cold while excluding signs of potential worse underlying conditions, you will make millions of dollars. But because the problem of turning all the available medical literature into data that can be acted upon, bridging the gap between a device and a human being with more than cameras and voice recognition whilst being ridiculously cheap and easy to maintain I’m quite confident even my grandchildren can be doctors (if they want to) and almost all of their responsibilities will still be performed by them. I assume you are a healthy human being and luckily you weren’t forced to consult doctors for severe healthcare problems, but I assure you, once you happen to touch problems we assume to be even slightly more complex than the healthy population has to deal with, you will be happy that a human doctor is making the decisions, answers your questions, performs diagnostic tests and treatments on you and talks to your relatives. And if your are able to develop a tool that frees me from even 50% of the administrative bulls… I have to deal with, I will more than happily buy it. TLDR: medical problems are more complex and inaccessible by non-human objects than it is commonly acknowledged by the layman. If you have a credible solution to a fraction of the problems we face and are able to sell it, you will be a millionaire.
