Taken On Trust: Ensuring Safe, Secure Access To Health Data For Research

Affected person information is considered one of our Most worthy sources for understanding well being and tackling illness. Nevertheless, we should be certain that delicate affected person information is stored secure and safe whereas it’s getting used for analysis. On this article, Well being Knowledge Analysis UK’s chief expertise knowledgeable, Gerry Reilly, discusses the important thing improvement in well being information analysis safety: Trusted Analysis Environments.

Well being information analysis depends on permitting scientists to entry delicate affected person information, to allow them to uncover patterns and particulars about illnesses and coverings that will in any other case be tough and even inconceivable to search out.

Nevertheless, affected person well being information will be extraordinarily private and delicate, so it’s important that it’s stored safe and solely accessed for reputable analysis functions. “We have got to have the ability to return to the sufferers and say thanks for letting us use your information, we’ll take care of it correctly”, says Gerry Reilly, Well being Knowledge Analysis UK’s chief expertise knowledgeable.

At present, most well being information, equivalent to GP information, are stored in a safe database. Scientists can request entry to the info they should reply their explicit analysis questions and are then despatched anonymized extracts of the database, in a mannequin often known as ‘information launch’.

Though any private figuring out info has been eliminated, releasing delicate information on this approach remains to be a safety danger. What’s extra, it could possibly take a very long time for scientists to obtain the info they want, and once they do, it could already be outdated.

A secure haven for information

Trusted Analysis Environments (TREs) are the subsequent era of safe platforms for information analysis that might assist researchers get the info they want, while sustaining safety.“Trusted Analysis Environments present a secure expertise space that researchers can use to investigate anonymized patient-level information with out that information ever leaving that safe space,” explains Reilly.Moderately than sending datasets out into the world, TREs permit vetted researchers to return into the database and entry anonymized info in a secure, safe surroundings. It is a bit like having to go to a particular safe library to learn a valuable, uncommon guide, as a substitute of getting just a few badly photocopied pages despatched over to you.One instance of a TRE is the SAIL Databank in Swansea. SAIL allows scientists to entry anonymized information remotely, utilizing a safe gateway. The scientists conduct their analysis remotely throughout the secure, protected surroundings, and as soon as their evaluation is full, they will solely take away their statistical outcomes, not particular person affected person information.

TREs come of age throughout COVID-19

In addition to elevated safety, the TRE frameworks present fast entry to the most recent well being information, which has been significantly necessary through the COVID-19 pandemic when researchers wanted solutions rapidly. Many very important datasets are actually being fed into the UK’s 4 main nationwide well being data-focused TREs – the NHS Digital Knowledge Processing Service in England, Scotland’s Nationwide Knowledge Protected Haven, the Northern Irish Sincere Dealer Service, and SAIL in Wales – so it may be accessed safely and securely to assist the UK’s response and make clear this fast-moving new illness.For instance, information from the 4 million customers of the UK’s COVID Symptom Study app is being held by SAIL, so it may be safely accessed by vetted researchers eager to grasp extra about when, the place and the way COVID-19 is affecting the inhabitants.“As an alternative of ready 3-6 months to do their evaluation, researchers have been in a position to entry the info they want in days. It is proven us how useful TREs are throughout a public well being disaster.” Reilly says. One other TRE that has been used to search out out extra about COVID-19 is OpenSAFELY. This platform was designed by scientists on the Evidence-Based Medicine DataLab at the University of Oxford, and the London School of Hygiene and Tropical medicine to permit extremely safe entry GP information for researchers exploring the dangers from COVID-19. The platform has been used to investigate the info from 17 million folks, revealing a clearer image of who’s most in danger from dying from COVID-19. The study was one of many first to indicate that folks from black, Asian and minority ethnic (BAME) backgrounds have been extra more likely to catch coronavirus and die from the illness. It additionally confirmed that being male, having uncontrolled diabetes or extreme bronchial asthma additionally will increase the danger of dying from COVID-19.

Chopping down on file fatigue

Moreover elevated safety and fast entry to up-to-date information, TREs additionally take away the necessity to switch large information information to researchers – an issue that’s solely getting extra urgent as the scale of recent well being datasets grows.“Analysis linking issues like imaging information, genomic information, and digital well being information isn’t going to be accomplished by information launch as a result of the info units required are simply too large, so TREs are the one scalable approach ahead,” says Reilly.Though TREs supply a number of apparent benefits for well being information analysis, Gerry says that almost all analysis remains to be performed utilizing information launch and we’re nonetheless early on within the journey.“Some scientists imagine that TREs scale back productiveness as a result of they’re extra advanced,” says Gerry. “Going forwards, we have to strike a stability between safety and productiveness, however I imagine we’re making large strides, and the alternatives are simply unimaginable.”
