Why Do We Need Health Care Data?

Understanding the data being gathered and analyzed is necessary before we can talk about health data analytics and its function in the healthcare industry. A significant amount of health data is also being obtained, kept, and analyzed, in addition to data on the processes and procedures of the commercial side of the healthcare industry.


All information about a patient’s or a population’s health is called health data. Healthcare practitioners, insurance providers, and governmental agencies use a variety of health information security (HIS) and other technical methods to collect this data.


We can see trends related to place, socioeconomic status, race, and propensity in addition to an overall picture of each patient. The gathered information can be divided into certain datasets, which can subsequently be examined.


A number of technologies and systems are employed to capture, store, distribute, and analyze health data obtained through multiple channels. Among these tools are:


  • Health Information Technology (EHRs)
  • Personal Health Information (PHRs)
  • Master patient indexes, patient portals, and 
  • electronic health services (e-prescribing) (MPI)

Smartphone apps for health

The amount of healthcare data that can be studied grows every second, thanks to digital data collection. A sizable amount of data is being collected in real-time due to the expansion of electronic record keeping, apps, and other electronic communication of data collecting and storage.


The complexity of these data sets prevents the use of conventional processing tools and storage systems. Cloud storage is crucial for “Big Data” operations. While handling sensitive patient information, cloud storage is essential because it is designed to be secure. It has helped to reduce the rising expense of health care because it is also very economical.

Large-scale data analysis and COVID-19

Everyone can clearly see the effect COVID-19 has had on the healthcare sector. To understand what has been occurring across the globe during this pandemic, you don’t have to be well-versed in medicine.


The influence COVID-19 is having on medical data analytics is something that most people fail to see, though. Big data tools, according to HealthITAnalytics, have become more important in the decision-making process for healthcare. Politicians, academics, and other stakeholders are turning to big data analytics and predictive models to assist in distributing resources, forecast surges, improve patient care and outcomes, and implement preventive measures.


The fight against COVID-19 has benefited greatly from the analysis of big data and health data. The rate at which the data arrive is almost constant. It is now possible to respond to and treat patients more effectively thanks to the analysis of such health data.


Because of the pandemic, there has been a huge increase in the amount of health data collected and altered, enabling more sophisticated analyses. The unfortunate thing is that COVID-19 is “shining a sharp spotlight on health care’s core flaws,” as the report puts it. Health data sharing between companies has many challenges, and the methods used to gather and evaluate the data are noticeably nonstandard.


This pervasive issue became clear as contradicting and constantly-changing information was being disseminated to the public in the early stages of the pandemic. When it came to COVID-related material, we noticed a shift towards skepticism, with many people continuing to hold outdated assumptions about how to treat this infection.


Yet, these issues may now be fixed because of the limelight that COVID-19 has shone on them. These errors can be learned from by service providers, academics, and politicians, who can then collaborate to develop a better, more standardized approach to big data in healthcare.

Healthcare Data Analytics: Their Significance

We can get all the data we want, but it will be useless if we don’t know what to do with it. We need a centralized, organized method to collect, store, and analyze data effectively and efficiently.


In recent years, data-gathering procedures in healthcare settings have been reduced. The data may now be used more effectively in predictive modeling, which helps to enhance daily operations and patient care. We may use both datasets to track trends and make forecasts rather than focusing only on historical or present data. We can now prevent problems from occurring and monitor the results.


Health care delivered on a fee-for-service basis is fading into history. A significant movement towards predictive and preventative actions in terms of public health has occurred recently as a result of the increased demand for patient-centric, or value-based, medical care. Data allows for this. Practitioners can spot patients at a high risk of acquiring chronic illnesses and provide treatment before symptoms appear, as opposed to just treating the symptoms as they appear. Preventative care may help ward off costly long-term problems and hospital stays, which reduces expenses for the doctor, insurance provider, and patient.


Practitioners can forecast infection, worsening, and readmission risks using data analytics if hospitalization is necessary. This, too, can aid in reducing expenses and enhancing patient care results.


Take the COVID-19 pandemic into consideration. The data being gathered is being evaluated in real-time to better understand the virus’s effects and forecast future patterns to stop the spread and further outbreaks.

Healthcare Analytics – Types

The same data analysis cannot be used to address every query. Many of the concerns posed in healthcare settings can be resolved using various forms of big data analytics.

  • Descriptive Analytics

In order to make comparisons or find trends, descriptive analytics makes use of historical data. Using this kind of study is advisable to respond to inquiries concerning the past. With descriptive analytics, we can learn about the past.

  • Predictive analytics

Predictive analytics uses recent and old data to create predictions about the future. The models developed using these analytics are most useful for predicting potential future events. Through predictive analytics, we can see into the future.

  • Prescriptive analytics

Advanced analytics will also forecast potential outcomes. This kind of analytics heavily relies on machine learning. The data offered can assist in selecting the best course of action. Prescriptive analytics can give us insight into the actions that should be taken to achieve the best possible result.

Role of Data Analytics in Healthcare Solutions

If used correctly, healthcare data management may result in better treatment. While using centralized datasets, it is possible to get rapid access to the required data anytime and wherever it is required. Efficiency is increased across the board with the advent of big data analytics. Improved data results in better healthcare.

Predictive Modeling

Predictive modeling is used to analyze recent and past data to forecast future results. In order to find patterns and forecast outcomes, algorithms use data mining, machine learning, and statistics. On a macro and micro level, predictive models created from the health records being gathered offer solutions.


Predictive analytics can notify medical professionals of potential risks. Behavioral data analysis enables us to forecast treatment outcomes, possible hazards for chronic illness, and even the danger of self-harm. The health information gathered can be utilized at the individual patient level for risk assessment, readmission prediction, treatment, identifying infection and deterioration, and much more.


A significantly wider range of applications for predictive modeling exists. Without the application of these models, managing population health is not possible. In understanding the things to come, prevention steps can be performed. Outbreaks and consequences can both be forecast.


Predictive modeling can even be utilized in administrative applications to boost productivity and cut expenses for everyone.


Expense savings for healthcare

Healthcare is pricey. Furthermore, all of these prices are just going up. Nonetheless, we are witnessing a transition from fee-for-service payment methods to value-based care.


Healthcare providers and organizations can gain precise models for reducing costs and patient risk by using predictive and prescriptive analytics. Health data analytics can lessen fraud, manage costs associated with supply chains, prevent equipment breakdowns, and reduce appointment no-shows in addition to the patient-centered advantages already highlighted.
