The public option for population health improvement

Addressing Social Determinants to Improve Population Health
Integrating Social Care into the Delivery of Health Care: Moving Upstream to Improve the Nation’s Health
The Public Option How to Expand Freedom, Increase Opportunity, and Promote Equality

This is what JAMA article says about population health

While health care organizations may not be equipped to address each of the root causes of their patients’ conditions, they need to broaden their perspective on how to address social determinants of health and use their expertise to influence initiatives on education, housing, employment, and other important health related social issues that take place beyond their immediate clinical purview.

"Need to broaden their perspective", this is the message for health care organizations according to the articoe. I'm not so sure about it. The message is not only for health care organizations, it is for public policies. This is much more difficult to address when there is not a public option for the whole population. A new book sheds light on this topic for the US policy.

How altruistic behaviors reduce pain

Altruistic behaviors relieve physical pain

That's it. You'll find the details in PNAS article:

For centuries, scientists have pondered why people would incur personal costs to help others and the implications for the performers themselves. While most previous studies have suggested that those who perform altruistic actions receive direct or indirect benefits that could compensate for their cost in the future, we offer another take on how this could be understood. We examine how altruistic behaviors may influence the performers’ instant sensation in unpleasant situations, such as physical pain. We find consistent behavioral and neural evidence that in physically threatening situations acting altruistically can relieve painful feelings in human performers. These findings shed light on the psychological and biological mechanisms underlying human prosocial behavior and provide practical insights into pain management.

Fighting against techno-eugenics

A Chinese scientist who shocked the medical community last year when he said he had illegally created the world's first gene-edited babies has been sentenced to three years in prison by a court in southern China.
He Jiankui announced in November 2018 that he had used a powerful technique called CRISPR on a human embryo to edit the genes of twin girls. He said he modified a gene with the intention of protecting the girls against HIV, the virus that causes AIDS. Many scientists expressed concerns about possible unintended side effects of the genetic changes that could be passed down to future generations.
Last fall, He also indicated there might be another pregnancy involving a gene-edited embryo. The court indicated that three genetically edited babies have been born.
The closed court in Shenzhen found He and two colleagues guilty of illegal medical practice by knowingly violating the country's regulations and ethical principles with their experiments, Xinhua news agency reported. It also ordered He to pay a fine of about $430,000.

Such unethical medical behavior is the worst news of 2019. And this article explained last June the reasons:

The link between CCR5 and HIV is fairly well studied. Disabling CCR5 removes the doorway HIV uses to enter and infect cells, but it does so only for some strains of HIV; there are others that don’t need CCR5. Further, the genetic sequence He’s edits produced does not match this well-studied variant of CCR5; in fact, it has never been observed in humans or animals. In other words, no one has any idea whether the variant with which Lulu and Nana are now living will affect HIV immunity or anything else.
That’s a key issue: Genes don’t do just one thing. Most illnesses and traits are influenced by dozens, hundreds, even thousands of DNA variations. Each of our roughly 20,000 genes is linked to many different aspects of our physiology and health. So what else does CCR5 do? A variant that provides protection against HIV also seems to increase susceptibility to a number of more common diseases, like flu and West Nile virus.
CCR5 has also been linked to brain function, which led to some sensational headlines and media speculation that the gene-edited babies might have enhanced brains. There are likely myriad other processes to which CCR5 contributes that we don’t know about yet. To that point: before the recent study, no one had researched whether the CCR5 mutation resulted in better or worse health over a person’s lifetime.
The CCR5 story illustrates a flaw in the logic that underlies gene editing. Efforts to change one gene to affect one illness in a future person ignore the fact that health is the result of infinitely complex interactions within and outside a person’s body. In most cases, the presence or absence of a particular genetic variant is not the sole determinant of a disease or condition.

And this article reminds us that, despite the appearance of agreement, ethical questions that have surrounded human germline editing for years have yet to be properly addressed.

How confirmation bias contributes to polarization

Confirmation bias in the utilization of others’ opinion strength

Humans tend to discount information that undermines past choices and judgments. This confirmation bias has significant impact on domains ranging from politics to science and education. Little is known about the mechanisms underlying this fundamental characteristic of belief formation. Here we report a mechanism underlying the confirmation bias. Specifically, we provide evidence for a failure to use the strength of others’ disconfirming opinions to alter confidence in judgments, but adequate use when opinions are confirmatory. This bias is related to reduced neural sensitivity to the strength of others’ opinions in the posterior medial prefrontal cortex when opinions are disconfirming. Our results demonstrate that existing judgments alter the neural representation of information strength, leaving the individual less likely to alter opinions in the face of disagreement.

The notion that the strength of disconfirming opinion is not necessarily proportionate to its impact on belief change is in accord with anecdotal and ‘real-world’ observations in domains ranging from science to politics. The underlying process is remarkably flexible, with the neural circuitry involved switching on a trial-bytrial basis from high sensitivity to relative neglect, contingent on whether the opinion is confirmatory or disconfirming. This process may leave the individual less likely to alter opinions in the face of disagreement.

Interesting article from Nature. So what? Is there any exercise to train the neural sensitivity of our posterior medial prefrontal cortex? If so, I would suggest these exercise to some guys.

Ethical algorithms like hammers?

Main messages:

All decision-making—including that carried out by human beings—is ultimately algorithmic. The difference is that human decision-making is based on logic or behaviors that we struggle to precisely enunciate. If we humans had the ability to describe our own decision-making processes precisely enough, then we could in fact represent them as computer algorithms. So the choice is not whether to avoid using algorithms or not, but whether or not we should use precisely specified algorithms.

Machine learning is a powerful tool that has many extant and potential benefits.  Technology companies such as Google and Facebook of course rely on products powered by machine learning for much of their revenue—but as these techniques grow in applicability, their scope and societal benefits grow as well.

The result is that, at least for a while, the critics of the algorithmic approach may often be right. There are many consequential domains where algorithmic tools are still too naive and primitive to be fully trusted with decision-making. This is because to model the forest, we need to start with the trees. This book offers a snapshot of exciting strands of research aimed at developing ethical algorithms, many of which are still in their very earliest days.

Global pharmaceutical market vs. local regulators

Regulating Medicines in a Globalized World: The Need for Increased Reliance Among Regulators

As defined by the World Health Organization (WHO), recognition occurs when a regulatory authority accepts the regulatory decision of another authority “as its own decision;”— reliance takes place when a regulatory authority takes into account the work products of another authority (e.g., inspection reports, scientific assessment reports, joint assessment reports produced together with another authority) to help inform the receiving authority's own regulatory decision, which, in the end may differ from the made by the initial authority using the same products. 

Recognition and reliance are the first steps towards an improvement of real coordination between regulatory bodies. If the pharmaceutical market is global, the regulators should cooperate for a coherent global regulation.

Effect of Teaching Bayesian Methods Using Learning by Concept vs Learning by Example on Medical Students’ Ability to Estimate Probability of a Diagnosis

Why do we need more bayesian reasoning?. Can we improve clinical decision making? The answer in this JAMA article.

Although bayesian reasoning has been widely promoted in the literature as a diagnostic strategy, there has been scant evidence that teaching bayesian reasoning actually improves diagnostic accuracy. Providing learners with relatively brief instruction on these abstract concepts appeared to significantly improve their diagnostic performance in comparison with simply providing a number of relevant examples or no relevant instruction.

 The previously reported discrepancy between human probability estimation and optimal bayesian probability estimation has become traditionally accepted in the psychology and medical literature as cognitive biases, including base-rate neglect, anchoring bias, confirmation bias, and representativeness, all of which suggest suboptimal revision and have been purported to be a primary cause of diagnostic error.13,14 However, on closer scrutiny, much of this evidence was derived from situations that were not representative of the typical diagnostic setting. One highly cited study9 used a screening situation in which the base rate was very low and any positive test result, even one with excellent operating characteristics, would have most likely been a false-positive result. Participants in that study also appeared to exhibit semantic confusion by confusing the posttest probability with the conditional probability that was presented in the problem-solving exercise.

Laboratory medicine as a data science

Data science, artificial intelligence, and machine learning: Opportunities for laboratory medicine and the value of positive regulation

Artificial intelligence (AI) and data science are rapidly developing in healthcare, as is their translation into laboratory medicine.

These are the four areas that the authors consider that AI will have impact:

• Processes and care pathways
• Laboratory test ordering and interpretation
• Data mining, early diagnosis, and proactive disease monitoring
• Personalized treatment and clinical trials

Meanwhile there is a long way ahead.

The fight between commercialism and professionalism in medicine (3)

The Price We Pay
What Broke American Health Care--and How to Fix It

Health care is perhaps today’s most divisive, territorial political issue. But many of the needed solutions are not partisan; they’re American. We are at a pivotal juncture. Spending on health care threatens every aspect of American society. The time for commonsense reform has arrived. All of us can play a part in driving badly needed reforms, both in the marketplace and in the policy world.

As a society, we should embrace a basic set of patient rights, including a right to obtain a timely quote for a shoppable medical service. Lawmakers should look at the price transparency trails blazed by Florida, New Hampshire, and Maine. The prerequisite of any free market is viewable pricing information—not just inflated charges, but the actual amounts of settled bills. New policies should ensure a level playing field to make the free market functional again, to cut the waste and restore competition to the marketplace.

I disagree with the author. Competition it is not the tool for a fairer health care. Wishfull thinking will not drive us to an improvement.

Ensuring America's Health

The Public Creation of the Corporate Health Care System

A second book on the same topic on US healthcare. And the regulatory messages are:

Despite the political uproar surrounding the ACA, many citizens, including the legislation's opponents, acknowledged the need for some type of reform. Indeed, ACA antagonists were most effective raising the specter of how federal programming would worsen health care rather than boasting about prevailing arrangements. Poor service distribution, fragmented care, and uneven service quality had long characterized U.S. medicine. But policymakers and voters were primarily concerned about the uninsured and the exorbitant costs that ranked American health care as the world's most expensive. These flaws helped push the ACA over the finish line. And the program has thus far proven resilient, withstanding presidential and congressional contests as well as significant court challenges.
The ACA built new rooms atop a defective, jerry-built edifice. The public option would have put the nation firmly on the path toward a nationalized, universal system by creating a government-managed plan and using regulations and mandates to enfeeble and eventually drive out private coverage. Readers can decide for themselves the wisdom of creating a centralized system. Nonetheless, because the ACA failed to secure fundamental, structural reform, it will be unable to rein in costs while also maintaining or improving the quality of care. Indeed, this narrative has illustrated how a fusion of public and private power constructed an institutionally tangled health care system that, even under the banner of comprehensive reform, policymakers were ultimately unable to rescue from the insurance company model.

Right now it seems that ACA is not enough. Let's wait and see.
