Covid vaccine landscape

 Evolution of the COVID-19 vaccine development landscape

Currently there are 321 vaccine candidates for COVID, however only 33 have entered clinical trials.

Although the leading COVID-19 vaccine candidates have progressed to advanced stages of clinical development at exceptional speed, many uncertainties remain given the lack of robust clinical data so far. Moreover, given the highly unusual circumstances associated with developing a vaccine during the evolution of a novel global pandemic, probability of success benchmarks for traditional vaccine development are likely to underrepresent the risks associated with delivering a licensed vaccine for COVID-19. The most advanced candidates are expected to begin reporting data from pivotal studies over the coming months, which if positive will be used to support accelerated licensure of the first COVID-19 vaccines.

Population Health amidst pandemic

 Fitting Community-Centered Population Health (CCPH) Into the Existing Health Care Delivery  Patchwork. The Politics of CCPH

COVID-19 Crisis Creates Opportunities for Community-Centered Population Health Community Health Workers at the Center

Norbert Goldfield et al provides a useful reflection on the current moment in US. And says:

The virus has exposed glaring weaknesses that cannot be unseen. The US health care system’s embrace of patient-centered care is being tested.

We need a new paradigm, one that moves from a patient-centered care system to a community-centered health and social care ecosystem. Unlike much of the current US medical care system, the community sector has lacked funding and development. Strong and consistent sources of support are needed to make this sector viable and keep it flourishing.

Politics will ultimately determine how our current patient-centered acute care–focused health care system will change. The wealthy undoubtedly will continue to have an outsize influence on any legislation promoting CCPH. Despite this fact, we will at least think about becoming better in improving our response before the next pandemic hits.

Both articles deserve being read.

Dual practice regulation

Dual practice regulatory mechanisms in the health sector A systematic review of approaches and implementation 

Dual practice refers to physicians concurrent activity, public and private. The conflicts of incentives arise and some regulatory mechanisms are needed.

The regulatory mechanisms that have been employed across countries can be divided into three categories: those that advocate for total banning of DP, those that allow it with restrictions and those that allow it without restriction. Countries that attempted total banning of dual practice, as in Portugal and Greece, could not easily stamp it out. DP continued to exist on a wide scale in Portugal until the ban was lifted in 1993 (Oliveira and Pinto, 2005). Similarly, the ban in Greece from 1983 to 2002 did not prevent public doctors from practising privately (Mossialos et al., 2005). Efforts to ban dual practice failed because of lack of capacity to enforce it. The resources needed to enforce it may not be commensurate with the benefits a country gets from banning it. Moreover, banning dual practice has in some countries been associated with the migration of health workers, especially specialists, from the public to the private sector as well as an international brain drain (Buchan and Sochalski, 2004; Mossialos et al., 2005). In LMIC settings where health workers are underpaid and members of the general population are willing to pay for more convenient and possibly better services, this option might not be viewed as legitimate or even feasible.

 The second category is allowing dual practice with restrictions. This was the most frequent approach used by countries. Financial and licensure restrictions as well as promotional incentives were employed. Financial restrictions included limiting private sector earnings, providing incentives to limit private sector activities, salary increases for public sector workers and performance-based payments. All financial restrictions intrinsically require well-established and adequate health financing systems to fund and monitor public and private sector activity. A combination of tax-based public financing, mandatory health insurance and private insurance might be necessary to counter the financial resource demands of this approach, while supervision, monitoring systems and transparent bureaucracies would be necessary to ensure that private sector activities and earnings are indeed limited and payments are matched by performance.

 Allowing DP without restrictions was noted in countries like Indonesia and Egypt, where DP is routine and accepted. An interesting point to note is that in both countries, the productivity of physicians far exceeded the capacity of the public sector to employ them. Because of the low salaries offered in the public sector, physicians are allowed to supplement their incomes with private sector earnings. This approach is unlikely to be feasible in countries with health worker shortages. Considering the three options of total ban, allowing dual practice with restrictions and allowing it without restrictions, the most feasible for the LMICs is allowing it with restrictions. With health workers who are underpaid, in short supply and working in areas with a high burden of disease, they will scarcely be able to satisfy the demands of the public or the private sector alone.

DRGs 101

 DIAGNOSIS-RELATED GROUPS: a question and answer guide on case-based classification and payment systems

WHO has released a report on DRGs that is useful as introduction to the concept and the design of payment systems.

The document consists of four parts:

Part 1 outlines definitions, terminology and the main conceptual aspects related to CBG and DRG.

Part 2 covers the assessment phase and highlights questions and issues that policy-makers should consider before taking the decision to introduce a CBG system.

Part 3 delves into the preparation phase by exploring policy and design aspects once a country has decided to introduce a CBG system.

Part 4 is concerned with the implementation phase and discusses implementation questions, requirements for system adjustments and the need for monitoring and revision in order to identify and address unintended impacts of a CBG system.

Improving CRISPR, a crowd of proteins

Improving CRISPR from Mammoth Biosciences; 

 Genome editing is the process researchers use to make targeted changes to an organism’s DNA (its genome). Scientists have used a variety of technologies for genome editing (see the history of genome editing here). However, since ~2012, CRISPR has made the genome editing processes much easier. CRISPR associated or “Cas” proteins drive this process. They are relatively easy to target to specific DNA sequences. They also work in many organisms.

Yet, the main Cas protein currently used for CRISPR genome editing, SpCas9, has limitations. In this post, we cover SpCas9’s limitations and how newly discovered Cas protein families, Cas14 and CasΦ, potentially overcome these limitations. We hope Cas14 and CasΦ will enable more efficient genome editing in diverse organisms and tissues.

Spillover effects of payment systems

 Randomized trial shows healthcare payment reform has equal-sized spillover effects on patients not targeted by reform

From PNAS: 

Changes in the way health insurers pay healthcare providers may not only directly affect the insurer’s patients but may also affect patients covered by other insurers.

This is the research question. And this is the result:

We use a payment reform in TM, which was randomly applied to some markets but not others, to study spillovers of healthcare payment reform. We find spillovers of the same sign and similar magnitude on privately insured MA patients. Naturally, our findings are specific to our setting; the existence, sign and magnitude of any spillovers may well vary across contexts.

Sounds good. However, there is a previous research question, which is the insurer's market share that allows to have the option to change the payment system. This former question is as relevant as the later one.

Health impact of social isolation and loneliness

Social Isolation And Health

The lonely century

Social isolation and loneliness are both terms that denote a degree of social disconnection. Social isolation is an objective state marked by few or infrequent social contacts. Loneliness is the subjective and distressing feeling of social isolation, often defined as the discrepancy between actual and desired level of social connection.

Social connection and connectedness encompass a variety of terms used in the scientific literature (for example, social support, social integration, social cohesion) that document the ways that being physically or emotionally connected to others can influence health and well-being. 

In this HA Brief, the author explains that loneliness impact on health may be greater than we think. Rather than being alarming, she shows a description of the situation, the evidence and a proposal for policy agenda.

And if you are not convinced, than I would suggest this book:

An unprecedented discovery


Mapping genetic regulation

The GTEx Consortium atlas of genetic regulatory effects across human tissues

A great step in research:
The GTEx v8 data release represents a deep survey of both intra- and interindividual transcriptome variation across a large number of tissues. With 838 donors and 15,201 samples—approximately twice the size of the v6 release used in the previous set of GTEx Consortium papers—we have created a comprehensive resource of genetic variants that influence gene expression and splicing in cis. This substantially expands and updates the GTEx catalog of sQTLs, doubles the number of eGenes per tissue, and saturates the discovery of eQTLs with greater than twofold effect sizes in ~40 tissues. The fine-mapping data of GTEx cis-eQTLs provide a set of thousands of likely causal functional variants. While trans-QTL discovery and the characterization of sex- and population-specific genetic effects are still limited by sample size, analyses of the v8 data provide important insights into each.

On being honest in politics

 Eliciting preferences for truth-telling in a survey of politicians

From PNAS: 

Voters who would like to accurately evaluate the performance of politicians in office often rely on incomplete information and are uncertain whether politicians’ words can be trusted. Honesty is highly valued in politics because politicians who are averse to lying should in principle provide more trustworthy information. Despite the importance of honesty in politics, there is no scientific evidence on politicians’ lying aversion. We measured preferences for truth-telling in a sample of 816 elected politicians and study observable characteristics associated with honesty. We find that in our sample, politicians who are averse to lying have lower reelection rates, suggesting that honesty may not pay off in politics.

Therefore, in this case, truth-telling is a dominant non-rational strategy in politics. We still do need more evidence. Maybe the next presidential election will provide us a confirmation of this article.

Pricing panic, massageing data

The Price of Panic. How the Tyranny of Experts Turned a Pandemic into a Catastrophe

So, what caused the viral panic? The panic and lurching government overreach were inspired not so much by deaths people knew about firsthand, and not so much by the virus’s murky origins in China. They were sparked by a few forecasts that had the smell of science. The World Health Organization (WHO) favored a single, untested, apocalyptic model from Imperial College London. The United States government took its cues from the Institute for Health Metrics & Evaluation (IHME) at the University of Washington. We now know these models were so wrong they were like shots in the dark. After a few months, even the press admitted as much. But by then vast damage had been done.

But what of those experts? They treated predictive models—which are at best complex conjectures about future events—as if they were data. And then, when the models flopped, they began to massage the data. To get past this catastrophe we will need to forgive, but we should never forget. We should do whatever we can to dismantle such experts’ unchecked power over public policy.

These experts, however, could never have done so much damage without a gullible, self-righteous, and weaponized media that spread their projections far and wide. The press carpet-bombed the world with stories about impending shortages of hospital beds, ventilators, and emergency room capacity. They served up apocalyptic clickbait by the hour and the ton.

History shows that you will rarely lose your job making predictions if you’re wrong in the right direction. On the other hand, you may well lose it if you’re right in the wrong direction. Neither rulers nor subjects welcome the bearer of bad, but true, news. (Especially if it’s bad news for power-grabbing elites.)

Being wrong in the right direction, though, often reaps reward. Early pandemic models indicated that only prompt and massive state action could save us. The models were wrong—way off—but they were wrong in the right direction. They gave politicians justification for taking over almost every aspect of citizens’ lives. They gave the press clickbait galore. We’re not assuming malice here. We assume that many of these folks were moved by concern and even love for others. The issue is one of incentives and human nature, not bad intentions.

Our imagined pandemic model has made a huge mistake. How to explain that whopping error? In a perfect world, the experts who created the model, publicized, and used it to create public policy would reassess the assumptions they fed into the model—A, B, and C—find the mistake, and try new ones, which may better match the “observables.”

But we don’t live in a perfect world with perfect experts. What if experts are loath to admit that they were wrong? (We know that’s a real stretch, but stick with us here.) What if they have been feted by the press and promoted to positions of authority and power? They have other options besides the humiliating one of going back to the drawing board. For starters, such experts can stop using the word “predictions” to describe the forecasts that the model has been spitting out. Now they’re just “scenarios” or “guidelines” or “projections.” But these are just word games. There’s little daylight between a forecast, a prediction, a guess, a scenario, and a projection. All those words describe what the model is doing when it says, If A, B, and C are true, then something like X will happen, give or take a margin of error. If nothing like X happens, then something’s wrong with at least one of the model’s conceptual inputs, that is, with one of the propositions that that model assumed to be true. At least one of A, B, or C must be wrong.

It's only one view. Uncertainty is everywhere, and you may find snake-oil sellers in every corner.

PS. Great post on pandemic models.

The burden of disease around the world

Global Burden of Disease (GBD) 2019

The Lancet latest issue: 

The potential to improve health by risk reduction is well reported in GBD 2019. All risks quantified in GBD collectively account for 48% of global DALYs. Exposure to many risks highly correlated with SDI has been steadily decreasing as global SDI has increased, including household air pollution; child growth failure; and unsafe water, sanitation, and handwashing. Additionally, there have been notable decreases in exposure to smoking. Figure 4 shows the annualised rate of change in exposure from 2010 to 2019 for select risk factors ordered by global attributable DALYs. Among the 15 leading causes of attributable DALYs shown, high systolic blood pressure, high fasting plasma glucose, high body-mass index (BMI), ambient particulate matter pollution, alcohol use, and drug use stand out because rates of exposure are increasing by more than 0·5% per year.

 Success in reducing the disease burden from causes of communicable, maternal, neonatal, and nutritional  CMNN diseases by global collective action to fund key programmes should be celebrated. Catch-up social and economic development is fuelling more rapid health progress in the lower socio-demographic index (SDI) quintiles. But there is reason to believe that, although the past 70 years have largely been a story of sustained improvements in health, rising exposure to crucial risks, such as high BMI, high fasting plasma glucose, and ambient particulate matter pollution, as well as stagnant exposure to many other behavioural risks, including diet quality and physical activity, might attenuate progress. Most alarmingly, the mortality decreases in cardiovascular diseases of the past half a century have slowed substantially, or even reversed, in some nations with high SDI. 

Good news!

Dying from COVID

 Magnitude, demographics and dynamics of the effect of the first wave of the COVID-19 pandemic on all-cause mortality in 21 industrialized countries

The total mortality effect of the COVID-19 pandemic is the difference between the observed number of deaths from all causes and the number of deaths had the pandemic not occurred, which is not directly measurable. The most common approach to calculating the number of deaths had the pandemic not occurred has been to use the average number of deaths over previous years—for example, the most recent 5 years—for the corresponding week or month when the comparison is made. This approach, however, does not take into account changes in population size and age structure, nor long- and short-term trends in mortality, which are particularly pronounced for some age groups52,53. Nor does this approach account for time-varying factors, such as temperature, that are largely external to the pandemic but also affect death rates.

We developed an ensemble of 16 Bayesian mortality projection models that each make an estimate of weekly death rates that would have been expected if the COVID-19 pandemic had not occurred. We used multiple models because there is inherent uncertainty in the choice of model that best predicts death rates in the absence of pandemic. 

I suggest you to find where is Spain...

Markets in Healthcare, some weaknesses and what to do about them

 The Role of Market Forces in U.S. Health Care

No market functions perfectly, however, and health care markets are more imperfect than most.

The article explains weaknesses of the market and some potential fine tunning to avoid them. And says: 

Many of the “single-payer” health care systems around the world have some market components, and many are actually expanding the role of markets. The more important question is how government and markets can complement one another. Essentially, we do not need to abandon markets — we can make them better. Specifically, relatively incremental actions, such as continued support for ACA  marketplaces, continued efforts to increase the effectiveness of transparency initiatives, procompetitive reforms to reduce the deleterious consequences of provider consolidation,5 and regulations to prevent the most severe market failures, such as limits on surprise billing or more aggressive caps on excessive prices in the commercial market, seem like first-order ways to improve market functioning with a relatively light touch.  If we fail to improve market functioning, stronger government involvement will most likely be needed.

My impression is that unless there is stronger government involvement there will no be equity of access, specially after covid pandemic.

Milgrom and Wilson on auctions and Nobel Prize

The Prize in Economic Sciences 2020

The quest for perfect auction

Additional readings

When basic and applied sciences meet together:

Milgrom and Wilson’s ground-breaking initial work should be regarded as basic research. They wanted to use and develop game theory to analyse how diferent actors behave strategically when they each have access to diferent information. Auctions – with their clear rules that govern this strategic behaviour – comprised a natural arena for their research. However, auctions have gained in practical signifcance and, since the mid-1990s, they have been increasingly used in the distribution of complex public assets, such as frequency bands, electricity and natural resources. Fundamental insights from auction theory provided the foundation for constructing new auction formats that overcame these new challenges. 

The new auction formats are a beautiful example of how basic research can subsequently generate inventions that beneft society. The unusual feature of this example is that the same people developed the theory and the practical applications. The Laureates’ ground-breaking research about auctions has thus been of great beneft, for buyers, sellers and society as a whole.

Long time ago, I studied my PhD with Milgrom-Roberts book on organizational economics, later I published an article on auctions for primary care in Hacienda Publica, using Milgrom ideas. It is a well deserved Prize, I know what it really means.

The future of work (2)

 A World Without Work. Technology, Automation and How We Should Respond

The struggle for subsistence was the challenge that preoccupied most of mankind. Our generation has been fortunate to wake up in a world where people need not be condemned to that fate, where there is in principle enough economic prosperity for us all to keep ourselves and our families alive. The looming problems—of inequality, power, and meaning—are just the consequences of this unprecedented
prosperity. They are the price we pay for the material abundance that some of us (though as yet not all of us) have been fortunate to enjoy. And in my view, it is a price worth  paying. 
In the twenty-first century, we will have to build a new age of security, one that no longer relies on paid work for its foundations. And we have to begin this task today. Although we cannot know exactly how long it will take to arrive at a world with less work for human beings to do, there are clear signs that we are on our way there. The problems of inequality, power, and meaning are not lurking in the distance, hidden out of sight in the remote future. They have already begun to unfold, to trouble and test our inherited institutions and traditional ways of life. It is up to us now to respond.

Health as a priority

Mckinsey Global Institute has released a relevant report:

In Prioritizing health: A prescription for prosperity, we measure the potential to reduce the burden of disease globally through the application of proven interventions across the human lifespan over two decades. By intervention, we mean actions aimed at improving the health of an individual. These range from public sanitation programs to surgical procedures and adherence to medication and encompass interventions recommended by leading institutions like the World Health Organization or national medical associations. We also examine the potential to reduce the disease burden from innovations over the same period.

Health reform, a lost chance (once again)


In the midst of covid crisis, our government created a Comitè d’Experts per a la Transformació del Sistema Públic de Salut. It gave them 2 months to solve such a complex issue, and this is the result. The message is clear, the implementation fuzzy. My impression is that if the Parliament asked for a reform and we delivered a report 6 years ago and nothing happened, now that the government is leaving it is not the best moment to think about it. Nevertheless, health reform, public and private, is as relevant as it was 6 years ago, but unfortunately nobody is taking charge.

PS. Someday I'll explain what really happened, the enablers and the blockers, and why all this has still impact in the current situation.

Integrated care as organizational innovation

Innovative Integrated Health And Social Care Programs In Eleven High-Income Countries 

High-income countries face the challenge of providing effective and efficient care to the relatively small proportion of their populations with high health and social care needs. Recent reports suggest that integrated health and social care programs target specific high-needs population segments, coordinate health and social care services to meet their clients’ needs, and engage clients and their caregivers. We identified thirty health and social care programs in eleven high-income countries that delivered care in new ways. We used a structured survey to characterize the strategies and activities used by these programs to identify and recruit clients, coordinate care, and engage clients and caregivers. We found that there were some common features in the implementation of these innovations across the eleven countries and some variation related to local context or the clients served by these programs.

Needs segmentation, Patient coordination and Engagement are the crucial topics. More details inside the article.

Patients are not consumers

 Patient-Centered Care, Yes; Patients As Consumers, No

There are numerous calls for building health care delivery systems that are more patient centered. The focus on patient-centered care has increasingly begun to rely upon, and even merge with, the concept of patients as consumers. Early references to patients as consumers were made by patient advocates who were attempting to challenge professional and corporate dominance in health care. Today, “consumer-driven” health care has become associated with neoliberal efforts to emphasize market factors in health reform and deemphasize government regulation and financing. In our view, a narrow focus on consumerism is conceptually confused and potentially harmful. The consumer metaphor wrongly assumes that health care is a market in the usual understanding of that term, that the high cost of US health care is a function of excessive consumer demand, and that price transparency and competition can deliver on the promise of reducing costs or ensuring quality. Furthermore, a consumer metaphor places disproportionate burdens on patients to reduce health care costs, and it could erode professional obligations to provide appropriate and effective care.

So, all said.
