What is Data Analytics in Healthcare?

Before moving forward, let’s answer the most important and frequently asked questions: “What is data analytics in healthcare industry?” Healthcare data analytics allows businesses to analyse the healthcare-related raw datasets to uncover hidden, useful insights, trends, and patterns. Including this process can lead to the improvement of both the patient and the business levels. 

There are more than one type of healthcare analytics that can be included in the healthcare business. Have a look, we have mentioned them below. 

Types of Healthcare Analytics

1. Descriptive Analytics: 

This analytics depends on historical data of patients to determine the trends and benchmarks in healthcare. Descriptive analytics allow us to acquire certain insight into the past and answer questions like how many patients were hospitalized, what is the average BMI (Body Mass Index) of a particular patient population, what treatment plan was prescribed in a particular disease or symptoms. The answers to these questions are provided using simple statistics such as counts, percentages, averages, and standard deviations. 

2. Predictive Analytics: 

This kind of analytics applies modeling and forecasting to forecast what will occur in the future in healthcare, like which patients will be the most at risk of hospitalization, or which patients can change their home therapy to in-center care. Historical data are used to build models, forecast events in the future, and, based on sophisticated methods of computation, like machine learning, data scientists use past data to do so. Through predictive models, we would be able to estimate risk scores on individual patients and understand which patients might need further care. However, predictive analytics also have their share of issues in healthcare, and this is going to be mentioned subsequently.

3. Prescriptive Analytics: 

This form of analytics involves the application of machine learning in finding possible solutions to healthcare issues. Prescriptive analytics using machine learning in healthcare can be considered a more advanced technique that takes predictive analytics a step further. It proposes certain measures that can be undertaken to alter the forecasted result and adopt more informed decisions. 

4. Diagnostic Analytics: 

This form of analytics assists us in knowing why events took place, so we can then answer questions of why patients visited the hospital or why patients missed home therapy. In further research of the data, we can understand more about the answers that were discovered in descriptive analytics. Diagnostic analytics presupposes exploration of past data, and some statistical methods are applied to understand why some events took place.

Moreover, healthcare synthetic data is also being applied to analytics to model real-world conditions whilst preserving patient privacy and improving model training.

5. Population Health Analytics: 

Population health analytics refers to the examination, analysis, and data breakdown of data that will put the major health issues into perspective and answer questions that will focus on how resources may be distributed to eliminate the issues that contribute to poor health conditions among the population.  

It assists the payers and provider networks to take a holistic look at the member populations, as well as to assist quality improvement, care intervention, and case management initiatives to provide patient-centred care and cost reduction.  

Such data comes from many different sources, such as patient surveys, clinical records, claims data, wearable devices, and socioeconomic databases. The inclusion of the social determinants of health, including economic status and living conditions ,gives the overall picture of population health.  

All these categories of data analytics necessitate the use of various tools and methods, and each of them has its practical uses in healthcare organizations and for patients.
