Let us look at the topics that we will be going through in this blog on applications of Data Science in healthcare:
Why do we use Data Science in Healthcare?
According to a study, the data generated by every human body is 2 terabytes per day. This data includes activities of the brain, stress level, heart rate, sugar level, and many more. To handle such a large amount of data, now, we have more advanced technologies and one of them is Data Science. It helps monitor patients’ health using recorded data.
With the help of the application of Data Science in healthcare, it has
now become possible to detect the symptoms of a disease at a very early stage.
Also, with the advent of various innovative tools and technologies, doctors are
able to monitor patients’ conditions from remote locations.
In earlier days, doctors and hospital management were not able to handle multiple numbers of patients at the same time. And due to the lack of proper treatment, the patients’ conditions used to get worse.
However, now, the scenario has changed. With the help of Data Science and Machine Learning applications, doctors can be notified about the health conditions of the patients through wearable devices. Then, hospital management can send their junior doctors, assistants, or nurses to these patients’ homes.
Hospitals can further install various equipment and devices for the diagnosis of these patients. These devices built on top of Data Science are capable of collecting data from the patients such as their heart rate, blood pressure, body temperature, etc. Doctors get this real-time data of the patients’ health through updates and notifications in mobile applications. They can then diagnose the conditions and assist the junior doctors or nurses to give specific treatments to the patients at home. This is how Data Science helps in caring for patients using technology.

factors in healthcare analytics. Due to the lack of proper information about a patient,
the condition can get worse. Thus, information or data about the patient must be collected efficiently. This data can be anything from the patient’s blood
pressure, body temperature to sugar level. After collecting the patient’s data,
it is analyzed to search for patterns and correlations in it.
This process tries to identify the symptoms of a disease, the stages of the disease,
the extent of damage, and many more.
Then, the predictive analytics model built on top of
Data Science makes predictions on the condition of the patient. Also, it helps in making
strategies for the appropriate treatment that should be given to the patient.
Therefore,
predictive analytics is a very useful technique and it plays a major role in
the healthcare industry.
The major benefits of predictive analytics in healthcare are given below:
- It helps in the
management of chronic diseases.
- It efficiently monitors and analyzes the demand for pharmaceutical
logistics.
