In science and healthcare, the amount of data needed to answer important questions keeps expanding. Large health databases are currently being created due to new technology. These technologies include better value genome sequencing, digitising medical tools, and expanding electronic health records (EHRs).
These vast datasets can provide important insights and eventually enhance lives. Recent groundbreaking studies that illustrate the power of big data in health research include
This article outlines the value of applying consistent formats and models to create standardised datasets that can be accessed and used for research and innovation in healthcare and research.
"Whilst the amount of data available for research is growing, the majority of users of health data (64%) lack the knowledge necessary to standardise data quickly. This results in researchers spending too much time preparing the data for analysis."
"80% of data scientists'
time is spent cleaning
& organising data."
Whilst the amount of data available for research is growing, the majority of users of health data (64%) lack the knowledge necessary to standardise data quickly. This results in researchers spending too much time preparing the data for analysis.
Furthermore, according to some estimates, data scientists devote 80% of their work to organising and cleaning data.
Data must be transformed into interoperable formats to solve these health data analysis problems. This process is known as data standardisation.
Common Data Models (CDMs) are being increasingly utilised in the healthcare sector to overcome the lack of consistency in health data. Examples of clinical CDMs are the Observational Medical Outcomes Partnership (OMOP) CDM and Clinical Data Interchange Standards Consortium (CDISC).
Data can be efficiently merged when standardised to these CDMs, making it more useful than the sum of its components alone. The standard approach to data transformation provided by CDMs makes it possible to share research tools and data throughout different nations, sources, and systems.
Combining and assessing information is much simpler if all health data are organised following a single and consistent standard.
It is clear that a lack of or limited health data standardisation stalls research progress. The table details some key benefits of performing health data transformation techniques.
There are many different sources and formats of health information. Only when the data is made interoperable can it be effectively combined to produce new insights. It is essential to standardise health datasets to ensure data quality and accelerate collaboration for maximum insights and discoveries.
Look out for the next blog in our series, where we will describe the technical challenges researchers and clinicians can face when standardising health data and some of the solutions currently being developed.
