The significance and influence of knowledge in healthcare is bigger than it has ever been, with entry to really large-scale datasets and highly effective analytical tooling creating the potential to ship transformative outcomes for society. Such examples embody the function of knowledge in response to the COVID-19 pandemic and vaccine improvement. Take Austin Well being, who onboarded 20k+ sufferers remotely through the pandemic to evaluate COVID-19 danger. By unlocking all of their information, together with their digital well being report (EHR) system, their self-service COVID display screen device offered next-best-action to sufferers, decreasing danger of an infection by 85% by informing them to remain dwelling. In actuality the use circumstances are boundless. The Division for Well being and Social Care whitepaper, “Information saves lives: reshaping well being and social care with information” additional highlights the influence that high quality information property can have throughout well being and social care. In short, it outlines 4 functions of how information can be utilized:

  • For the direct care of people
  • To enhance inhabitants well being by the proactive concentrating on of companies
  • For the planning and enchancment of companies
  • For the analysis and innovation that can energy new medical therapies

To help these goals throughout the well being {industry}, academia, and life sciences there’s a want for researchers to entry and collaborate on delicate information. This may vary from analysing digital well being information, by to exploring scientific trial outcomes with the aspiration for researchers, analysts, and builders to create consumable outcomes from delicate information that in the end enhance the life and wellbeing of residents—with out breaching information privateness legal guidelines.

Nevertheless, present approaches typically depend on many small initiatives working in silos with a number of copies of large datasets being distributed throughout groups and initiatives. This results in prices handed alongside to the patron, making well being care costlier and fewer accessible.

In his paper, Higher, broader, safer: utilizing well being information for analysis and evaluation, Professor Ben Goldacre particulars the necessity for collaboration and highlights the challenges going through the analysis neighborhood attributable to present approaches to analysis. While the principle problem can finest be summarised as “How can we facilitate entry to NHS information by researchers, commissioners, and innovators, whereas preserving affected person privateness?”, there are different challenges past safety which can be attributable to information being disseminated throughout a number of silos:

  • Duplication danger – as information is distributed to many siloes, the inherent danger of knowledge breaches and privateness violations is elevated
  • Restricted central oversight – a number of siloes with their very own governance layers and controls imply there is no such thing as a central authority for governance, auditing and entry management
  • Duplication price – a number of environments imply a number of know-how implementations and prices, together with the related sources to handle and preserve mentioned environments
  • Duplication of effort and complexities round information entry, resulting in a discount in analytic high quality

Mentioned intimately within the Goldacre evaluation, Trusted Analysis Environments (TREs) are options designed to ship on these necessities and sort out the challenges head on. TREs present safe environments and information platforms the place researchers can collaborate and securely entry delicate information while offering the mandatory tooling for them to provide helpful outputs and insights.

Though there’s loads of materials out there about TREs already, two additional good sources are offered by HDR UK and NHS England (as NHS X) which go into nice element concerning the “why we’d like TREs” and the advantages they drive, with instance advantages from NHS England proven beneath:


In the previous couple of years, the necessity for such safe improvement areas for analysis and innovation has grown considerably, with the COVID-19 pandemic accelerating this shift. Examples of present TRE programmes embody the Scotland Information Secure Haven programme and the UK Safe eResearch Platform in Wales.

Though the necessity for TREs is nicely understood, there has not typically been a finest strategy or “blueprint” that may permit well being organisations to ship such an surroundings with out appreciable price, effort and improvement. Variations of TREs can differ, with no “normal” strategy on the market. This has resulted in a plethora of TREs being produced, creating a fancy panorama of options and approaches.

At a excessive degree although, TREs typically look to stick to the 5 Safes Framework across the accountable use of knowledge:

  • Secure Individuals – Solely skilled and accredited researchers can entry the information
  • Secure Initiatives – Information is barely used for moral, permitted analysis with the potential for clear public profit
  • Secure Settings – Entry to information is barely attainable utilizing safe know-how programs
  • Secure Information – Researchers solely use information which were de-identified to guard privateness
  • Secure Outputs – All analysis outputs are checked to make sure they can’t be used to determine topics

The excessive degree structure and information move are nicely described with the graphic beneath from the Trusted Analysis Environments Information for Newcomers:
