The weirdest health financing system of the world (2)
Tracking Universal Health Coverage: 2017 Global Monitoring Report
If I had to summarise the best outcome of health policy in the last century in western countries, I would say mandatory health insurance. No doubt. And the joint report by WHO and WB reminds us that there is still a long way to achieve such goal for the whole population in the world. Mandatory insurance is the most efficient way to solve the failures of the health insurance market. We al know the details and difficulties that arise as a result of information asymmetries and opportunistic behaviour.
Therefore the recommendation is clear, for those that already have a mandatory system, keep on it. This is precisely what hasn't happened here. In 2012 the system changed from universal towards a social security based membership funded by taxes. The weirdest health financing system of the world.

Measuring morbidity in large populations
MODELIZACIÓN ECONÓMICA DEL AJUSTE POR RIESGO DEL GASTO SANITARIO PER CÁPITA SEGÚN MORBILIDAD EN LA COMUNIDAD VALENCIANA
There is a unique study on measuring morbidity in a large population. In Valencia (4.7 million inhabitants) the Clinical Risk Group classification system has been applied. And you may find the results comparing the whole population, and one Department (Denia). The study shows details about the utilization and costs related with morbidity. Interesting application that replicates former ones. Epidemiologists, clinicians, policy makers and managers should be interested in using these approaches for taking decisions.

Changing the production function of diagnostic tests
Next-generation diagnostics with CRISPR
Last week while reading Science I noticed a short and crucial article. Up to now CRISPR technology was focused on gene editing, now we can say that its usefulness is widening into diagnostics. It may change completely molecular diagnostics of "infectious diseases through detection of Zika virus (ZIKV), Dengue virus (DENV), and human papillomavirus (HPV) in human samples, and noninfectious diseases, such as detection of gene mutations in circulating cell-free DNA from lung cancer patients." The production founction of lab testing would change completely.
Several articles explain details about it. The fight for patents is going to start again on CRISPR diagnostics. And this are unfortunately bad news.
Anyway, Science article reminds us:

Anyway, Science article reminds us:
These emerging diagnostic tools will by necessity be compared to standard diagnostics to ensure sensitivity and specificity and will need to be field-tested to guarantee performance in patient care settings, as environmental conditions and end-user application might affect performance. Proven assays, if affordable, promise to improve care in resource-limited settings where undifferentiated febrile illness is the norm and where gaps or delays in diagnosis, targeted care, and infection control contribute to infectious disease mortality and spread.More details in The Verge.

Cost-effectiveness of genome sequencing (2)
Application of next-generation sequencing to improve cancer management: A review of the clinical effectiveness and cost-effectiveness
If you want to go deeper on the issue, have a look at this article. It is focused on one disease, cancer and tries to combine clinical effectiveness and cost effectiveness. Sounds good. At the end you'll see that the number of available studies is limited (6), but that's the situation and these are the conclusions:

At the end you'll see that the number of available studies is limited (6), but that's the situation and these are the conclusions:
We report the rate of successfully detecting mutations from the clinical studies. The incremental cost-effectiveness ratio and sensitivity analysis outcomes are reported for the cost-effectiveness articles. Fifty-six articles reported that sequencing patient samples using targeted gene panels, and 83% of the successfully sequenced patients harboured at least 1 mutation.
In our evaluation of the effectiveness of NGS, we found that NGS is effective at identifying mutations in cancer patients, and we reported that 37% of the diagnosed patients proceeded to receive therapy matching their genetic profile. However, with only 6 articles available that assess the cost-effectiveness of NGS in various settings, it remains an area for future research to determine whether the technology is cost-effective in routine cancer management.PS. Today this blog has surpassed its 200.000 visits. That's great! Thank you for your loyalty.

Cost-effectiveness of genome sequencing
Are whole-exome and whole-genome sequencing approaches cost-effective? A systematic review of the literature
It is quite difficult to talk about value in genetic tests without any reference to analytical validity, clinical validity and clinical utility. Once these three issues are appropriately solved, then we need to assess costs. Cost effectivenes makes sense once this three steps are covered successfully.
An analysis of cost-effectiveness of whole genome/exome sequencing it sounds too generic if there is no reference to specific baseline that allows to estimate incremental cost-effectiveness ratios.
That's the reason why a recent article trying to review existing studies fails to achieve any conclusion.

Diagnosing diseases and editing genes
CRISPR: The gene-editing tool revolutionizing biomedical research
The WIRED Guide to Crispr
A New Startup Wants to Use Crispr to Diagnose Disease
Take your time and read Wired and watch CBSNews. It will provide an exciting perspective of CRISPR. And just to end, imagine that diagnostic tests could be based on CRISPR while you read the last piece of WIRED.
We are closer than you may think.
