Medicine trends

The future of medicine

A new supplement in Nature explains the main trends in Medicine. It is really helpful to have a quick look focused on those approaches that are the more promising for the next future. From the issue, I would pick one article: A CRISPR edit for heart disease, A one-off injection to reduce the risk of cardiovascular disease is now a prospect thanks to advances in gene editing.This is amazing, it changes current perspectives on the first cause of death worldwide (18 million people per year).

 In 2014, Musunuru and his team showed that more than half of Pcsk9 genes in the mouse liver could be silenced with a single injection of an adenovirus containing a CRISPR–Cas9 system directed against Pcsk9. This led to a roughly 90% decrease in the level of Pcsk9 in the blood and a 35–40% fall in blood LDL cholesterol⁴. Next, they used a mouse engineered to contain human liver cells, and tuned the CRISPR–Cas9 payload to target human PCSK9⁵. The team succeeded in showing that the human gene can also be switched off.

This is changing the focus of drug research, and a recent article explains the new approach.  Let's see if finally delivers what they say.

Setting priorities explicitly (or not)

PRIORITISING HEALTH SERVICES OR MUDDLING THROUGH

A chapter of this book explains who does what in prioritisation (resource allocation and rationing).
I've found of interest this classification of rationing:

• Rationing by denial. Exclusion of specific services or treatments from the National Health System portfolio (often explicitly) or from one healthcare provider (near always implicitly) that believes that such treatment or service is inappropriate.
• Rationing by selection. Exclusion of some patients of some treatments because they do not meet certain eligibility criteria fixed by the regulator (often explicitly) or the provider (near always implicitly). 
• Rationing by delay. The demand that cannot be met by a rigid offer remains on hold (waiting list) and the wait acts as a barrier to access and, in many cases, as a de facto denial of care. 
• Rationing by deterrence. Barriers placed, either consciously or unconsciously, by the healthcare providers that make it difficult for patients to find out about, and book appointments with, some healthcare services. 
• Rationing by deflection. Patients being shunted off to another institution, agency or programme. 
• Rationing by dilution. Services continue being offered to patients, but with fewer resources, and the quality of care gets worse

 And the summary:

In conclusion, adequate priority setting is not about choosing either to muddle through implicit rationing or to be corseted by an exhaustive, rigid and explicit interventionist structure at the macro, meso and micro decision-making levels. This dichotomy fails to capture the complexity of priority setting in practice. We need more and better explicit priority setting, not to substitute but to improve implicit priority setting.

In vitro, veritas

El Diagnóstico In Vitro Hoy. Un cambio de paradigma en la calidad de vida y en el proceso de atención a los pacientes

A new report highlights the role of clinical laboratory in medical decision making. Though its increasing complexity, it requires larger recognition in terms of the value that creates. Some selected statements:

Desde el punto de vista de los costes, el IVD es económicamente muy accesible, tanto por su competitividad en costes de producción como por no necesitar de grandes inversiones iniciales en equipamiento: – El IVD consume una proporción de recursos de los hospitales muy baja, inferior en todos los estudios al 4% del coste hospitalario y supone en promedio un 0,8% del total del gasto sanitario4. – La mayoría de equipamientos se ceden mediante la contratación de los reactivos, lo que elimina la barrera de inversión inicial para su adquisición 

El Diagnóstico In Vitro es sin duda el proceso diagnóstico más utilizado con carácter habitual. A diferencia de otros grandes equipamientos diagnósticos que se utilizan muy selectivamente, el IVD se utiliza masivamente para la gran mayoría de pacientes y en la mayoría de los actos asistenciales.

Paradójicamente, y a diferencia de otros equipamientos, el IVD es cada vez más complejo tecnológicamente, pero también más simple en su utilización. La innovadora y alta tecnología incorporada internamente contrasta con la apariencia de simplicidad. – Si se compara con otros equipamientos médicos de alta tecnología, como los de diagnóstico por la imagen o de cirugía robótica, los equipamientos de IVD, cada vez más pequeños, automatizados y fáciles de utilizar, tienen una visibilidad más bien escasa.

I suggest a close look.
