The healthcare sector produces copious amounts of data, everyday. Electronic medical records, billing, healthcare services, wearables data and various study pieces continue to churn out huge amounts of information. This gives healthcare providers a powerful opportunity to ensure quality patient care, driven by actionable knowledge from past patient records.Of course, data science is making it happen.

Data scientists worldwide are slowly revolutionizing the healthcare sector with the aid of advanced machine learning and analytics. From optimizing care quality to gaining operational experience, they work by leveraging the value of data to improve any aspect of health care service.
Healthcare analytics have the ability to reduce healthcare costs, predict infection outbreaks, avoid preventable diseases and enhance overall quality of life.

Data science applications in healthcare:

Workflow Optimization and Process Improvements
Databases and cloud computing technology will significantly reduce the time needed for the operation and improve the quality of the test results. Less time and reliable test results contribute to improved workflow performance. Better performance leads to higher recovery times, quicker emergency response and, most importantly, fewer catastrophic results due to sepsis and other factors requiring immediate reactions.

Medical Image Analysis
Analysis of medical images is one of the most promising areas of pattern recognition technology. It is one of the essential elements of the evaluation and the subsequent selection of the treatment plan.

Predictive Analytics
Predictive analytics, another application of data science in healthcare, helps “predict the future” where the models are based on statistical knowledge from existing databases of historical data, which are continuously updated. Visualized predictive analytics transform complex observations into knowledge that can help make fast decisions , which is critical in healthcare.

The following are some of the cases of usage in which data science makes a significant difference in the healthcare sector:

Diagnostics
Using data science, researchers can use profound learning techniques to analyze detailed clinical and laboratory records and make a faster and more accurate diagnosis. Analysis of data will help them to identify early signs of a problem and allow the doctors to provide patients with preventive care and better treatment.

Public health
Most health care agencies, in an attempt to boost overall patient health, have already begun using big data. This data holds the key to understanding a particular geography for the general public health. It can be analyzed by data scientists to create heat maps related to parameters such as population, health conditions, regional medical outcomes of people etc.

Reduced healthcare costs
Healthcare costs tend to only increase over time, and this continues to be an important factor in providing a better patient experience. Data analysts may look at billing data and health program details relating to payment and variables groups. This enables them to dig up to the patterns in room use and the services needed to meet patient needs.

Optimal staffing
Data analytics has the solution to having optimum staff available in emergency situations, it can forecast variations in patient visits based on historical data over the years and establish a trend in staff allocation based on previous admission patterns. That would give providers an idea of when the center would need what level of staff.

In addition to improving patient care, data science helps health care professionals solve workforce allocation problems, insufficient medical resources and high cost of service.
