Catching up on Big Data & Healthcare

November 24, 2017

The health area is characterized by the management of huge data volumes. What if those data are processed and provided to the health professionals and their patients or, even to the health system at large? Not only one, two, three patients are healed but also it enables to enhance the population’s health, in general. This level of analysis of information, due to its wide variety and speed, saves lives in the health world.

 

When Big Data got involved in the health industry, endless opportunities and challenges emerged causing continuous progress. At the same time, it created a revolution in the medical world because it proposes alternative ways to collect clinical evidence.

Its use implies a great progress in all areas, such as pharmacoepidemiology, in response to pharmacological treatments according to genetic profiles or lifestyles; prevention and forecasting of risks adverse reactions of medications; enhancement of the adherence to treatments; and consequently, an exponential growth of results in health. Likewise, costs reduction is evident.

 

One of the greatest challenges is the privacy of the information managed, which is sensitive. Having in mind that current technological systems are not properly prepared to contain Big Data projects, it will be essential to adequate the infrastructure and communications accordingly.

Below, we will make a summary of the health topics that most interested us.

 

Population Health

Population Health refers to the health’s overview of the population, not only based on the patient. Many of the diseases that individuals suffer are shared by others, as well as its causes, cultural elements, etc.

 

Reduce readmission index

Each visit to the doctor has a cost, wherefore unnecessary visits are an obstacle for the availability of resources for other patients that really need them. In this lecture they explained that in Baystate Hospital, 45% of the visits are “unnecessary” so the lecture was basically focused in PA (Predictive Analytics) and in the experience they were carrying out specifically in that health center. Applied to healthcare, predictive analytics uses technology and statistical methods to search through massive amounts of information, analyzing it to predict outcomes for individual patients.

 

Treatment based in evidence is increasingly more relevant

 

There are 4 factors that affect the most the treatment readmission of patients with hypertension:

1.    The level of diastolic blood pressure.

2.    The patient’s age.

3.    The year the physician graduated from medical school.

4.    The amount of target-organ damage.

 

As you can see, the third factor it is not related with the patient. The conclusion was that the education of the “oldest” doctors used to be focused in their experience and the education of the younger professional is based on “academic advances”. Wide variations in practice are often not related to differences among patients and to improve the treatment quality these variations should be minimized:

1.    Variation in response when evidence is lacking

2.    Variation in beliefs

3.    Variation in interpretation of evidence

 

Precision medicine

Nowadays we can benefit from the human genome to improve our health. The costs for sequencing the genome are decreasing and it is believed that we are not far from the fact that each person may carry his/her genome in his/her mobile device which would open a great range of opportunities for the precision medicine.
