A look at how Big Data is generated

How is so much data generated within the healthcare industry? Which are the touchpoints of data creation and analysis? To what end does the analytics drive changes within the healthcare industry?

Here are some points of data creation that together contribute to the voluminous data in healthcare:

Electronic Medical Records

The clinical history of patient data maintained by doctors provides a comprehensive picture of a patient’s health record. This includes the physician’s notes, diagnosis and treatment.

Other Clinical Information

Clinical data also include diagnostic and prescriptive records entered by doctors, patient profiles and medical prescriptions. There is also plenty of administrative data related to the logistics and supply of medicines used within the hospital. Insurance claims data is another set of healthcare data that is finding popular use amongst insurance companies.

IOT data

The proliferation of wearable devices, online health monitoring apps and connected medical devices; have generated huge streams of data in the IoT network. Medical devices and sensors like pulse monitors and electronic weighing scales; and wearables that track heart rate, blood pressure or activity levels; send streaming data to the cloud. Healthcare apps on smartphones track a user’s exercise activity and quality of sleep. All of this data is stored in the private cloud, for sharing and analysis by various stakeholders – insurance providers, health care practitioners, public health services, medical and pharmaceutical manufacturers, and world health organizations that function as community health watchdogs.

Data maintained by Insurance providers and Government Health Agencies

Medical Insurance covers healthcare, accidents and specific diseases. This gives rise to huge data related to policy coverage types, claims and government health plans.

Social Feeds

Healthcare providers are much dependent upon brand image for patient loyalty and competitive edge in a crowded, competitive marketplace. So unstructured data generated from social media conversations and forums are another source of data, analyzed for improving patient care and customer services.

Opt-in Genome and Research Registries

Many genomic research organizations gather volunteered patient data to support research in clinical trials and preventive healthcare.

Together, these touchpoints of data creation contribute to gigabytes of structured and unstructured data within the healthcare industry.

How Big Data Analytics is bringing value in Healthcare

Big data analytics offers various benefits of data-driven insights to individual healthcare practices as well as large facilities or Government health departments. At the micro level, predictive analytics and models help to offer better patient care and optimization of resources. At the macro level, healthcare data collected across agencies, regions, and ethnicities over a span of time; can help develop a comprehensive picture of global health conditions for data-driven policy making.

POPULATION HEALTH ANALYTICS IS USED FOR

Public health management

  • Analytics of data related to diseases, patterns of incidence, and outbreaks; can help understand the cause of outbreaks and locations to predict and prevent the future occurrence.
  • Such public health data when shared between participating agencies like the government and civic planners can support the discovery of hidden patterns and linkages.
  • For instance, data related to dengue outbreaks can not only help the civic authorities investigate the underlying cause in the location, but also facilitate suitable measures to control the spread.
  • The spread of Ebola disease could be contained only through analysis of data collected at local sites and healthcare facilities.
  • This hasn’t only enabled the timely deployment of medicines, equipment and health care providers to the locations, but also helped to develop models that could predict the sites of high-risk incidence even before their occurrence.

Policy-making by global health organizations

Data collected from individual health practitioners, facilities, hospital, pharmaceutical and insurance companies, government health and municipal departments; together help build world health databases. Analytics of the data help determine, for instance, demographies at high risks of malnutrition or disease and support appropriate policy making and regulations.

CLINICAL DATA ANALYTICS IS USED FOR

Patient healthcare management

Patient data analytics is used to ensure quality control of healthcare, and ensure that the norms of diagnosis and treatment are adhered to. Advances in analytics application can now even spot a patient not taking his medicine!

Improved services and preventive healthcare

Analytics of patient data across departments can help determine quick and cheap ways to diagnose and treat patients. Drug prescriptions and success rates are correlated to discover optimal treatments, drugs and devices. Clinical trials are analyzed using big data analytics prior to the launch of a medical device or drug.

Patient Profiling

Predictive analytics models help identify patients who may benefit from measures like diet, lifestyle changes and therapies. Analytics also helps identify whether patients affected by say, an auto-immune disease has the risk of contracting other diseases like diabetes. In case of diseases related to specific ethnicities, analytics of affected patients can help better disease management.

Finding cures for diseases

Genome analytics is being used to develop insights into the human genomes to detect patterns for detection of diseases like cancer. As no two persons have the same genetic sequences, response to the line of treatment also varies for persons. The study of genomic medicine creates huge data, which analyzed can uncover unknown correlations and hidden patterns. Doctors are now finding value in these insights to engineer a correct treatment or drug suited to the individual level.

Pharmaceutical / medical equipment companies to meet requirements of patients and hospitals

Patient record, drug prescriptions, disease incidence data and lab tests; help pharmaceutical companies to leverage predictive analytics for production and supply of medicines, and medical devices.

Actuarial use

Hospitals partner with insurance providers to share patient data and hospital admission data. Predictive analytic models built on such data matched with actuarial tables, help to develop health plans and devise insurance premiums.

OPERATIONAL ANALYTICS IS USED FOR

  • Fraud Management– Analysis of insurance claim requests can help identify cases of fraudulent claims. Similarly, insights into hospital processes can help identify fraud.
  • Safety Monitoring– The large volumes of streaming data generated in hospitals when analyzed, can help monitor safety measures and predict negative event occurrence.
  • Optimising facility performance– Analytics as a business intelligence (BI) strategy can reap the benefits of operational efficiencies. For instance, analysis of hospital admission rates can help identify issues like poor emergency care or staff inadequacies.

Performance analytics of different points of operational silos and bottlenecks can aid reduction in wastage and inefficiencies. Resource use in areas like energy consumption, security services, and store supplies; can be better optimized with analytics.

The big data ecosystem allows equipment diagnostics and analytics in real-time for timely maintenance and prevention of system breakdowns. This ensures a seamless facility operation and enhanced patient service, with better patient safety, and facility brand ratings.

FINANCIAL ANALYTICS

Ultimately, healthcare practitioners, facilities and government hospitals are financially accountable to shareholders or government audit reports. Analytics of the huge amount of financial data, can help facilitate claim processing, enable risk assessment, manage the revenue cycle and prevent financial crime.

Case Studies from India and the World

  • Apollo Hospitals in India tackled the problem of ‘Hospital Acquired Infection’ using an analytics model.
  • Disease and infection data across clinical and non-clinical departments like microbiologists, laboratory teams, doctors and pharmacologists; were leveraged to discover preventive and prescriptive treatment methods to tackle in-house infections.
  • The Hospital for Sick Children in Toronto captures and analyses medical monitor data in real time to drive“near-real-time decision support and retrospective analysis” of treatment.
  • Atlanta (U.S.) based Piedmont Healthcare deployed analytics tools to provide better outcomes for its Medicare patients with pneumonia.
