With the help of technical revolutions like healthcare software development, predicting, identifying trends and patterns, gaining actionable insights, and limiting the spread of illnesses have been possible. This involves executing a variety of analytical operations on both historical and real-time data.

Global Big Data Analytics in Healthcare Market

In this post, we’ll go over what is meant by “Healthcare Data Analytics” or Healthcare Analytics, some of its applications, and the role of visual analytics in Healthcare Analytics.

1. What is Healthcare Data Analytics?

Health data analytics is the practice of examining data with a variety of tools with the purpose of spotting patterns and trends that can then be used to inform and direct decision-making. Controlling and monitoring the spread of illnesses is the primary application area for Healthcare Data Analytics.

Analytical rigor in data collection and processing is the backbone of healthcare data analytics. The term “data analysis” is commonly used to describe the method of processing data sets in order to gain useful insights that can be used to guide better business decisions.

Healthcare professionals in the Healthcare industry may use data visualization in the same way that it is employed in any other industry. Data Analytics is practiced to conduct in-depth data analyses and show complex data in a way that is easy to understand and interpret. Patient care attempts, positive/negative feedback, or any other real-time information that might aid in decision-making could all form the basis of an assessment of the data.

When it comes to improving patient outcomes and operational efficiencies, the healthcare sector generates a massive quantity of data but has trouble turning it into actionable insights. One goal of data analytics in healthcare is to remove roadblocks to data’s widespread use for clinicians. Following are a few more:

  • Facilitating the exchange of healthcare information between internal and external stakeholders and the visualization of such information for the general public.
  • Allowing healthcare providers to adapt more swiftly to shifting healthcare markets and settings through the provision of accurate data-driven projections in real time.
  • The automation of low-impact data management operations is improving healthcare companies’ ability to collaborate on data and generate new ideas.

2. Types of Healthcare Analytics

Unfortunately, the same data analysis won’t work for every inquiry. Many problems in healthcare may be answered with the help of big data analytics. Below are major types of data analytics in healthcare.

Types of Healthcare Analytics

2.1 Descriptive Analytics

In order to make comparisons or find predicted trends, descriptive analytics examines data from the past. Questions regarding the past are best tackled using this method of investigation. Descriptive analytics allows you to better understand the past.

2.2 Predictive Analytics

Data from the present and the past are analyzed in order to foretell what will happen in the future; this is what predictive analytics does. Questions regarding the future are particularly well suited to the predictive models generated by this sort of analytics. 

2.3 Prescriptive Analytics

The results of prescriptive analytics will be predicted as well. This kind of analytics relies heavily on machine learning. With this data, you can make an educated decision on what to do next. With the help of prescriptive analytics, you can figure out what steps need to be followed to achieve the best possible results.

2.4 Diagnostic Analytics

Similar to descriptive analytics, diagnostic analytics examines the past to provide an explanation. Diagnostic analytics, on the other hand, shifts the emphasis from the “what” to the more pressing “why” of an event occurrence in a certain context. The goal of diagnostic analytics is to pin down what made something happen.

Diagnostic analytics are utilized in the medical field to determine the cause of a patient’s condition and arrive at a correct diagnosis.

3. Benefits of Healthcare Data Analytics

3.1 Analyzing Clinical Data to Improve Medical Research

By compiling and evaluating clinical data from a wide range of sources, data analytics methods are being used to advance research in many branches of medicine. Electronic health records (EHRs), electronic medical records (EMRs), personal health records (PHRs), and public health records are among the most helpful collections of healthcare data.

Electronic health records (EHRs) compile a patient’s medical history in a standardized digital format, including X-rays and other medical pictures, diagnoses, care planning, sensitivities, and test results. This facilitates communication but also adds privacy and regulatory compliance restrictions that restrict the data’s potential use.

Electronic health records (EHRs) are comparable to electronic medical records (EMRs), however EMRs only incorporate data from the patient’s paper charts maintained in medical facilities like doctors’ clinics and hospitals. Their primary significance is in documenting a patient’s healthcare history over several healthcare professionals’ appointments and screenings.

The patient, rather than a healthcare practitioner, is responsible for keeping track of the patient’s medical history in the form of a personal health record. It is important to note that these records are meant to supplement the patient’s personal health management, not to serve as a legal substitute for the official medical records that healthcare practitioners keep.

Researchers can benefit greatly from the information included in public health records. Examples include the Cancer Research Data Commons (CRDC) hosted by the National Cancer Institute, which is a cloud-based data science system that connects data analytics tools with information sources for genomic, biochemical, comparative oncology, radiology, and other types of data.

There are three main ways in which medical researchers might profit from data analytics:

  • Researchers can use the findings to pinpoint potential avenues for streamlining hospital operations and enhancing the quality of patient care.
  • The findings improve healthcare delivery by allowing more precise diagnosis and individualization of therapy.
  • By tying together risk variables and health outcomes, cohort studies give doctors fresh perspective on chronic illness origins.

3.2 Using Patient Data to Improve Health Outcomes

Quality improvement in healthcare aims to reduce risks to patients while improving services. Healthcare providers gather and evaluate patient data, progressively in real time, to better comprehend today’s complicated health ecosystems; to create and employ a systematic strategy for improving patient results; and to build, test, and implement improvements to health systems.

Readmission rates, mistake rates, and the inability to detect at-risk individuals can all be reduced by examining patient data. 

In this kind of analysis, data including a patient’s glucose level, temperature, medical tests, and treatment preferences are utilized. Primary determinants of treatment quality for patients include:

  • A patient’s desired and most important health outcomes
  • When and how a healthcare organization’s methods affect the results that patients want to see
  • What role does the healthcare system, including its resources, equipment, laws, and other factors, have in determining the standard of treatment patients receive?

Getting immediate access to patient data that might help them enhance the quality of services they deliver is a major concern for healthcare providers. Concentrating on a few important performance indicators and collecting only as much data as is necessary to track those measures might help alleviate the stress caused by having too much patient information. The process involves qualitative evaluations of patient data and the provision of metrics that are easily available to physicians and can be monitored over time to identify and record progress.

In contrast to procedural measures of progress like unnecessary readmissions, hospital-acquired diseases, and fatalities, patient-reported outcome measures (PROMs) are concerned with the clinical outcomes that actually concern to patients and that are:

  • Complete healing after a severe illness
  • Thriving while dealing with a long-term health issue
  • Upholding human respect towards the end of life

Questions concerning the patient’s state of mind, pain levels, energy levels, ability to do daily tasks, and the severity of any symptoms are all part of the information gathered to evaluate the quality of services provided. It takes time and effort to obtain this information from patients, which slows the implementation of PROMs in healthcare settings. Because of the wide range of socioeconomic and demographic variables that affect patient outcomes, healthcare practitioners have a hard time drawing connections between patient-reported results and individual therapies.

The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed by the National Institutes of Health to assess and track patients’ emotional, psychological, and social well-being. The PROMIS Computer Adaptive Tests (CATs) are available for demonstration to healthcare providers in a number of different domains. These domains include unhappiness, anxiousness, distress, tiredness, pain behaviour patterns, pain intervention, physical function, and fulfillment with civil activities and social responsibilities.

3.3 Diagnosis and Treatment

Diagnosis and treatment cycles for individual patients have varied widely from recommended clinical protocols. By studying these outliers, it may be possible to enhance the quality of treatment offered, boost patient safety as well as happiness, and fine-tune the app’s performance.

The improved availability of trustworthy data from health information systems allows for a better understanding of transit patterns and anomalies.

Simply put, Data Analytics has proven instrumental in improving the quality of care provided to patients and medical staff alike, hence reshaping the Healthcare sector.

3.4 Gaining Operational Insights from Healthcare Provider Data

The quality of treatment patients get and the probability of excellent patient outcomes are strongly influenced by healthcare practitioners’ work procedures and organizational structures. The capacity to gather and evaluate relevant data from healthcare providers relating to these procedures and structures is essential for assessing the impact of process and organizational changes on results and operational efficiency in today’s complex healthcare settings.

A healthcare system-wide evaluation of present circumstances and an integration of the institution’s plans and objectives for change are essential first steps toward enhancing healthcare excellence and cost. Scheduling, charts, emergency planning, accounting, financial management, and regulation are some of the most probable operational sectors to gain from data analytics.

Some methods healthcare organizations and clinics have implemented to cut costs without compromising quality of care are the following:

Getting Rid of Extraneous Stuff – Variability in clinical practices, improper patient care, avoidable care-related injury and death, and a lack of adherence to established protocols contribute significantly to healthcare waste.

Economical Application of Technology – Analytics and other cutting-edge tools are difficult and time-consuming to implement. Applying data analytics in a cost-effective manner requires a framework that isolates and prioritizes the processes with the most potential for growth.

Developing More Space in Hospitals – Instead of spending money on pricey new healthcare facilities, providers may save money by using analytics to better control the need for healthcare organizations wards and other healthcare services.

Enhancements to The Project Management Framework – Project management is becoming increasingly important in the healthcare industry as businesses embrace the Triple Aim framework developed by the Institute for Healthcare Improvement to optimize patient experiences and administrative effectiveness.

Preserving Gains in Performance – Data-driven healthcare improvement initiatives frequently fall short in allocating sufficient funds to maintain their gains. An organization’s analytics initiatives have a better chance of succeeding in the long run if all relevant parties are involved from the start.

3.5 Improved Staffing Thanks to Analytics in Health Business Management

To solve staffing problems and find qualified candidates for open positions, healthcare organizations employ data analytics. However, there is a rising scarcity of skilled medical personnel, which complicates efforts to reduce healthcare costs, increase efficiency, and better serve patients. About 60% of healthcare organizations expenditures are consumed by labor expenditures, and this proportion is likely to grow as the healthcare industry continues to expand.

In healthcare settings, data analytics is being used to control costs by maximizing the efficiency with which services are provided to patients. One of Hawaii’s major healthcare providers, Hawaii Pacific Health (HPH), saved $2.2 million over 16 months by using a data-driven method to labor relations while preserving quality results.

In place of HPH’s previous manual paper-based management system, new computer-generated visual representations of labor usage were implemented, providing both real-time views of staffing and visual depictions of staff levels. It allowed the hospital to cut labor expenses without compromising the quality of care delivered or patient outcomes by providing management with a clearer picture of the performance of individual employees and teams, as well as the cost-effectiveness of hiring considerations.

As a result of implementing an automated method for managing labor, managers now spend only 15 minutes out of every four hours on scheduling. The hospital has hundreds of employees who all utilize the same automated system to coordinate their shifts and access other work-related materials.
