AI in Health Care

 Artificial Intelligence in Health Care. Benefits and Challenges of Technologies to Augment Patient Care

This report is being jointly published by the Government Accountability Office (GAO) and the National Academy of Medicine (NAM). Part One of this joint publication is the full presentation of GAO’s Technology Assessment: Artificial Intelligence in Health Care: Benefits and Challenges of Technologies to Augment Patient Care. Part Two is the full presentation of NAM’s Special Publication: Advancing Artificial Intelligence in Health Settings Outside the Hospital and Clinic.

 Policy Options to Address Challenges or Enhance Benefits of AI to Augment Patient Care

Policy OptionOpportunitiesConsiderations

Collaboration (report p. 32)


Policymakers could encourage interdisciplinary collaboration between developers and health care providers.

  • Could result in AI tools that are easier to implement and use within a providers’ existing workflow.
  • Could help implement tools on a larger scale.
  • Approaches to encourage collaboration include agencies seeking input from innovators. For example, agencies have used a challenge format to encourage the public to develop innovative technologies.
  • May result in the creation of tools that are specific to one hospital or provider.
  • Providers may not have time to both collaborate and treat patients.

Data Access (report p. 33)


Policymakers could develop or expand high-quality data access mechanisms.

  • A “data commons”–a cloud based-platform where users can store, share, access, and interact with data–could be one approach.
  • More high-quality data could facilitate the development and testing of AI tools.
  • Could help developers address bias concerns by ensuring data are representative, transparent and equitable.
  • Cybersecurity and privacy risks could increase, and threats would likely require additional precautions.
  • Would likely require large amounts of resources to successfully coordinate across different domains and help address interoperability issues.
  • Organizations with proprietary data could be reluctant to participate.

Best Practices (report p. 34)


Policymakers could encourage relevant stakeholders and experts to establish best practices (such as standards) for development, implementation, and use of AI technologies.

  • Could help providers deploy AI tools by providing guidance on data, interoperability, bias, and implementation, among other things. Could help improve scalability of AI tools by ensuring data are formatted to be interoperable.
  • Could address concerns about bias by encouraging wider representation and transparency.
  • Could require consensus from many public- and private-sector stakeholders, which can be time- and resource-intensive.
  • Some best practices may not be widely applicable because of differences across institutions and patient populations.

Interdisciplinary Education (report p. 35)


Policymakers could create opportunities for more workers to develop interdisciplinary skills.

  • Could help providers use tools effectively.
  • Could be implemented in a variety of ways, including through changing academic curriculums or through grants.
  • Employers and university leaders may have to modify their existing curriculums, potentially increasing the length of medical training.

Oversight Clarity (report p. 36)


Policymakers could collaborate with relevant stakeholders to clarify appropriate oversight mechanisms.

  • Predictable oversight could help ensure that AI tools remain safe and effective after deployment and throughout their lifecycle.
  • A forum consisting of relevant stakeholders could help recommend additional mechanisms to ensure appropriate oversight of AI tools.
  • Soliciting input and coordinating among stakeholders, such as hospitals, professional organizations, and agencies, may be challenging.
  • Excess regulation could slow the pace of innovation.

     

Status quo (report p. 37)

Policymakers could maintain the status quo (i.e., allow current efforts to proceed without intervention).

  • Challenges may be resolved through current efforts.
  • Some hospitals and providers are already using AI to augment patient care and may not need policy-based solutions to continue expanding these efforts.
  • Existing efforts may prove more beneficial than new options.
  • The challenges described in this report may remain unresolved or be exacerbated. For example, fewer AI tools may be implemented at scale and disparities in use of AI tools may increase.

CRISPR therapeutic success

 Treatment by CRISPR-Cas9 Gene Editing — A Proof of Principle

CRISPR-Cas9 Gene Editing for Sickle Cell Disease and β-Thalassemia

Transfusion-dependent β-thalassemia (TDT) and sickle cell disease (SCD) are severe monogenic diseases with severe and potentially life-threatening manifestations. BCL11A is a transcription factor that represses γ-globin expression and fetal hemoglobin in erythroid cells. We performed electroporation of CD34+ hematopoietic stem and progenitor cells obtained from healthy donors, with CRISPR-Cas9 targeting the BCL11A erythroid-specific enhancer. Approximately 80% of the alleles at this locus were modified, with no evidence of off-target editing. After undergoing myeloablation, two patients — one with TDT and the other with SCD — received autologous CD34+ cells edited with CRISPR-Cas9 targeting the same BCL11A enhancer. More than a year later, both patients had high levels of allelic editing in bone marrow and blood, increases in fetal hemoglobin that were distributed pancellularly, transfusion independence, and (in the patient with SCD) elimination of vaso-occlusive episodes. 

A pivotal moment. Great.

Prioritizing vaccines

 Who Goes First? Government Leaders and Prioritization of SARS-CoV-2 Vaccines

In US,

The vice president, Senate majority leader, House speaker, surgeon general, and members of Congress were among the first people vaccinated against Covid-19 in the United States. The president-elect, incoming first lady, vice president-elect, and her husband were also vaccinated in the first phase. Yet prioritization frameworks created by expert panels and adopted by states do not grant government leaders any special status, and giving them priority raises important questions of fairness and transparency. As vaccination proceeds, will other political or institutional leaders, or even celebrities and elite athletes, decide that prioritization plans don’t apply to them?

In another country, military personnel stole 300 vaccines that were for health personnel and administered themselves. I suggest you may guess which is this country....

Genethics in practice

 The ethics of genomic medicine: redefining values and norms in the UK and France

This paper presents a joint position of the UK-France Genomics and Ethics Network (UK-FR GENE), which has been set up to reflect on the ethical and social issues arising from the integration of genomics into routine clinical care in the UK and France. In 2018, the two countries announced enhanced cooperation between their national strategies, Genomics England and Plan France Médecine Génomique 2025, which offers a unique opportunity to study the impact of genomic medicine and relevant policies in different national contexts. The paper provides first insights into the two national strategies and the norms, values and principles at stake in each country. It discusses the impact of genomic medicine on established relationships and existing regulations, and examines its effects on solidarity and trust in public healthcare systems. 

A must read for neighbour countries that have forgotten their homework.

Mazzucato as a supplier of a flattering narrative for politicians (2)

Mission Economy. A Moonshot Guide to Changing Capitalism

My former post on a recent book by Mazzucato was based on a comment by McCloskey. Now, she has published a new one, and the best comment has been made by John Kay, clear message, I don't have anything to add.

Ever since 1969, people have asked themselves why if humans can land on the moon, can’t they solve pressing problems here on Earth, such as poverty, dementia and climate change. Mariana Mazzucato offers an answer: if only governments would apply the mission-driven methods of the Apollo project, they could.

Mission Economy, the new book from the high-profile economist noted for her advocacy of a more active state, contains many screenshots of the whiteboards beloved of brainstorming meetings, each with an ambitious goal at the top: secure the future of mobility, clean oceans, defeat cancer; below is a jumble of boxes and circles linked by multidirectional arrows.

We need a “solutions based economy”, driven and co-ordinated by more powerful governments engaged in every stage of the process of innovation.

But Apollo was a success because the objective was specific and limited; the basic science was well understood, even if many subsidiary technological developments were needed to make the mission feasible; and the political commitment to the project was sufficiently strong to make budget overruns almost irrelevant. Centrally directed missions have sometimes succeeded when these conditions are in place; Apollo was a response to the Soviet Union’s pioneering launch of a human into space, and the greatest achievement of the USSR was the mobilisation of resources to defeat Nazi Germany.

Nixon’s war on cancer, explicitly modelled on the Apollo programme, was a failure because cancer is not a single illness and too little was then — or now — understood about the science of cell mutation. Mao’s Great Leap Forward, a vain bid to create an industrial society within five years, proved to be one of the greatest economic and humanitarian disasters in human history. At least 30m people died.

Democratic societies have more checks and balances to protect them from visionary leaders driven by missions and enthused by moonshots, but the characteristics which made the Great Leap Forward a catastrophe are nevertheless still evident in attenuated version.

With political direction of innovation we regularly encounter grandiosity of ambition and scale; the belief that strength of commitment overcomes practical problems; an absence of honest feedback; the suppression of sceptical comment and marginalisation of sceptical commentators. All these were seen in Britain’s experience with Concorde, the Channel Tunnel and the AGR nuclear reactor programme, some of the worst commercial projects in history. More recently, there is the £12bn wasted on the NHS computerisation programme — a project that Mazzucato mentions, though only to blame private contractors for their failure to deliver on the political imperative.

On a smaller scale, Britain has suffered in the last year from the delays resulting from Public Health England’s insistence on central control of the coronavirus testing programme and the predictable fiasco of the attempt to sideline the expertise of Apple and Google in order to develop a uniquely advanced NHS test and trace app. And in September there was prime minister Boris Johnson’s “operation moonshot”, designed to control the coronavirus by testing 10m people daily in early 2021.

In contrast to these failures, the rapid development of vaccines is, at least provisionally, a success story. That development is not the product of visionary central direction but is the result of a competitive process with many different teams around the world attempting to be among the first across the finishing line.

Their work has drawn on a combination of existing academic science with the expertise in development and testing and the manufacturing and logistics capabilities of the global pharmaceutical industry. The role of government, appropriately, has primarily been in funding basic research and assuring that there will be a rewarding market for successful products.

Mazzucato lists “twenty things we wouldn’t have without space travel”. Athletic shoes, CAT scanners, home insulation, baby formula, artificial limbs. Yes, really. But beyond the ridiculous headline, we see the reality of productive innovation: a decentralised process in which developers draw on and help create the collective intelligence that leads to constant incremental improvement in so many fields — including better running shoes.

When historians of technology review the past 50 years, they may conclude that Neil Armstrong exaggerated when he announced “one giant leap for mankind”. The “new frontier” of the late 1960s turned out to be, not space, but information technology. And the development of IT was characterised by a striking absence of centralised vision and direction.

No moonshots; but piecemeal innovation through disciplined pluralism in which temporary winners were almost always displaced as they failed to anticipate the next step of the journey. Do you remember Digital Equipment, Word Perfect, Wang Laboratories, CompuServe, Netscape, AOL, BlackBerry? Each once a leader, now forgotten. Even Apple suffered more than one near-death experience, Microsoft failed to anticipate mobile computing or the cloud, IBM was swept out of the industry it had created.

Mazzucato has correctly emphasised the contribution of state funded basic research to Silicon Valley, but thank goodness the development was in the hands of Steve Jobs, Travis Kalanick and Elon Musk rather than a committee in the department of commerce.

No one has, or could have, the knowledge of present or future required to create or implement successfully the strategies that Mazzucato recommends. Take her modern signature example — Germany’s Energiewende, or energy transition to renewables. You will not learn from Mission Economy that this highly political, much publicised and wildly expensive project has brought about significantly smaller reductions in carbon emissions than Britain’s quiet, economically and socially beneficial substitution of gas for coal.

The failure of the Energiewende illustrates the dangers of moonshots and the mission economy. As talk of a “Green New Deal” becomes more frequent on both sides of the Atlantic, the prospect of more large, costly and ineffectual visionary projects grows.

Politicians readily fall in love with such proposals, and Mazzucato is not shy in reminding us how anxious they are to engage with her in discussing them. But the vision that propelled China’s economic development was not Mao’s Great Leap Forward or Cultural Revolution, but Deng’s “it doesn’t matter whether a cat is black or white if it catches mice”. It is more rewarding and effective to build better mousetraps than to shoot for a mice-free world.

The loss of professional autonomy and the hegemony of marketplace medicine

The Corporatization of American Health Care_ The Rise of Corporate Hegemony and the Loss of Professional Autonomy

Marketplace medicine has achieved such a strong ideological grip on our national consciousness, especially within the ranks of the health professions. Vested interests have been very persuasive in their propaganda against systems in other nations. Canada’s universal national health insurance model is maligned continually as unworkable here in the United States, even though our own Medicare system borrowed both its name and some structure from the Canadian national system—just without becoming universal for everyone! Americans do not realize how much of their money is wasted in this corporate healthcare system on overly priced, tax-supported care, coupled with such climbing out-of pocket personal payments for their families for this corporate healthcare system.

Clinical utility of genomic sequencing

 Clinical utility of genomic sequencing: a measurement toolkit

From Genomic Medicine:

For a diagnostic test such as WGS (whole genome sequencing) to be accepted into practice, commissioned in a health system, or receive coverage and reimbursement through health insurance, evidence of clinical utility and cost-effectiveness is generally required. Unlike prospective clinical research where the ‘effectiveness’ of an intervention can be easily tied to a predefined health outcome, the concept of clinical utility in genetic medicine is rarely uniformly defined nor necessarily directly tied to a specific health outcome. As such, generating and evaluating evidence of clinical utility is complex. The challenge in defining clinical utility today is compounded by the extraordinary heterogeneity of rare diseases, as well as the polygenic nature of more common conditions for which WGS is expected to be relevant. In this paper, we aim to extend earlier conceptualizations of clinical utility as applied to the diagnostic use of WGS and suggest that this framework not only be used as a tool for evidence review

 The application of this model to WGS includes six levels of efficacy: technical efficacy, diagnostic accuracy efficacy, diagnostic thinking efficacy, therapeutic efficacy, patient outcome efficacy, and societal efficacy (Table 1, Fig. 1). The model is hierarchical; achieving a given level of efficacy is often but not always contingent upon a demonstration of efficacy at the preceding level. As described in Fig. 1, levels 1–3 are necessarily contingent but beyond level 3, a genetic test can achieve therapeutic, patient outcome, and/or societal impact in ways that are contingent upon one another or independent of one another. We retain the levels of technical and diagnostic accuracy efficacy (i.e., levels 1 and 2) as essential starting points in our guiding framework as they are fundamental precursors to achieving clinical utility. However, since these laboratory-based components of efficacy are well-debated and described in the WGS literature and in recent guidelines published by members of our group27, we focus here on four levels of the efficacy model (i.e., levels 3–6) that align most directly with a broad definition of clinical utility and extend beyond laboratory-based components of efficacy. In emphasizing these four levels of efficacy as components of clinical utility, our intent is to encourage the use of a broad set of health and non-health-related indicators of value to bolster the state of evidence in this area, rather than to convey that all aspects of clinical utility need to be achieved for WGS adoption and reimbursement.

CRISPR 2020, a breakthrough year

 2020 Was the Turning Point for CRISPR

At an Oregon hospital in March, a patient with a type of inherited blindness became the first to receive a gene-editing injection directly into their eye. It was the first time CRISPR was used in an attempt to edit a gene inside someone’s body. A second person this year also received the experimental treatment, which is designed to snip out a genetic mutation responsible for their severe visual impairment.

 Despite its versatility, CRISPR is still error-prone. For the past few years, scientists have been working on more precise versions of CRISPR that are potentially safer than the original. This year, they made notable progress in advancing these new versions to human patients.
