Advances in technology open door for improved EHR to EDC transfer process.
Since the turn of the century, the pharmaceutical industry has actively supported the steady increase in the use of digital health technologies, including the important transition from paper-based health records to electronic health record systems (EHRs). An increasing proportion of health data is now digital (known from a regulatory perspective as eSource), bringing benefits to patients and clinicians alike.
While these advances in healthcare data have been mirrored in clinical trial settings, healthcare and clinical research activities remain, overwhelmingly, in separate worlds. Estimates are that 70%1 of clinical trial data is duplicated between electronic data capture (EDC) systems used for clinical trials and EHRs. The current methods for transferring this data continue to be manual, open to transcription errors, hugely wasteful and, ultimately, severely restricting to our ability to trial and launch potentially life-saving treatments for patients.
As an illustrative example, in a typical late Phase II/Phase III oncology trial encompassing around 200 patients, an average of 3.5 million data points will be entered into the EDC. Current methods involve a manual re-keying of a large proportion of this data from the EHR to the EDC, copying from screen to screen. This is followed by a manual data quality check known as source data validation (SDV), where it is not unusual for the clinical research associate (CRA) to also be accompanied by a hospital study coordinator. At each stage, time, effort, and costs multiply. In fact, around 20% of the total costs of a study (which can translate to between $16M-$24M2) is allocated to duplicating and verifying data.
The idea that the current approach is less than optimal is not a new one. Attempts have been made to achieve an electronic transfer of data from EHR to EDC systems going back up to 30 years. However, previous efforts have been highly localized, bespoke solutions that only work between specific (often in-house) systems, and so have not realized the benefits we need at scale.
Now, with a growing network of eSource-ready hospitals, advances in technology, and a growing imperative due to the increasing complexity and cost of clinical trials, a tipping point has been reached. High quality, structured data is now available; connectivity has seen huge improvements; and adoption of systems designed for interoperability is fast becoming the norm. Achieving a seamless transfer of data from EHR to EDC is now not only possible, but essential.
As Table 1 shows below, the cost savings that could be achieved in a typical oncology trial by using an automated transfer of data from EHR to EDC (referred to as EHR2EDC) in place of the current manual re-keying and verification, could result in a cost saving of $15,000 per patient.
We must also consider the time saving benefits–a staggering 87,500 hours in our average 3.5 million data point study—in a climate where every day that a drug is delayed from market, sponsors lose up to $8 million3, but also delays patient access to a potentially valuable new treatment.
Over the last decade the stage has been set for EHR2EDC. A potted history of some of the work in this space includes:
These program studies and developments have demonstrated that it is possible, not only to achieve an electronic transfer of a significant proportion of data from EHR to EDC, but to do this in a secure manner, with patient data remaining on site.
Aside from widespread adoption of electronic records in hospitals, the technical blocker to achieving EHR2EDC has historically been the absence of a scalable solution that would apply across multiple platforms, multiple trial sites, and for multiple sponsor requirements. Bespoke solutions developed to date would require too much adaptation and too much support to be commercially viable at scale.
In recent years HL7 FHIR has emerged as a standard format for packaging health data. A pivotal turning point was the US government’s 2016 21st Century Cures Act, which requires that all new EHR systems developed in the US use HL7 FHIR. This has paved the way for a new level of interoperability between different systems.
Further, the development of SMART on FHIR–an application programming interface (API)–which acts as the conduit for transferring data from one system to another–has completed the puzzle on the healthcare side to allow the development of software that can be scaled for use across multiple platforms and systems.
Regulators such as FDA and EMA have published guidance in recent years about the quality criteria and provenance metadata they would require in order to accept imported EHR data as valid eSource, to be included within regulatory submissions. EHR2EDC specifications align with and formalize this guidance as EHR system requirements and EHR metadata.
A common concern around system interoperability is in the reliability or suitability of the source data, to support highest quality standards required for clinical research.
Data such as laboratory data, medical history, adverse events, vital signs, demographics, medications, and more, is structured by design and high quality. This has been validated by studies conducted by the EHR2EDC consortium (TransFAIR9) and the recent Buckley MT et al.10 paper, that showed that between 37% to 54% of data in key structured data domains can be successfully sourced from the EHR.
The value of automating this structured data is high as it accounts for a considerable percentage of the data that is currently manually replicated in a typical clinical trial. When this is combined with a dramatic reduction in transcription errors (therefore higher quality data and reduced need for monitoring), the value for both hospital and sponsor is obvious to see.
A notable example of the potential of HL7 FHIR and SMART on FHIR is being demonstrated now in a partnership between AstraZeneca and IgniteData, as shown in Figure 1 below. IgniteData’s software, ‘Archer’ makes powerful use of HL7 FHIR and SMART on FHIR to provide a solution which can be adapted to work between different EHR and EDC systems. Running Archer in parallel with traditional methods, the project is already meeting critical success factors and will test and measure the efficiencies gained in time, cost and effort. Initially being deployed at two leading NHS hospitals, it is worth noting that enthusiasm from the hospital community has been high, with, essentially, a waiting list of hospital sites in line to be involved as the project scales.
In parallel, because of work by i~HD, Sanofi and other members of the EHR2EDC consortium, an eSource-readiness tool is being developed and to be made available this year. Based on the TransCelerate Site Capability Questionnaire and eClinicalForum eSource-Readiness Assessment Tool, this will allow hospitals to check for themselves whether they are ready to welcome this new era of clinical trials.
i~HD have also recently launched an updated quality accreditation scheme for vendors of EHR2EDC software, ensuring good practice and compliance, with the latest data protection thinking built in. Vendors such as IgniteData are working closely with them to consult, where required, on the design of this scheme to ensure it is fit for purpose, and to build commitment and industry buy-in.
Learnings so far, particularly from the TransFAIR study in 2018/19, point to the vast benefits that could be gained from widespread use of automated EHR2EDC technology, exemplified in oncology studies. Research points to the highest benefits in oncology due to the:
The ability to acquire data in near real time for these studies will not only save time and cost, but allow for patient safety and treatment assessments to be made more quickly and with a higher level of confidence, hence improving safety monitoring of patients in trials.
Furthermore, we believe that using real world data more broadly in clinical trial design, recruitment and execution will enhance the generalizability of new drugs. The resulting new dialogue will inform protocols and produce trial results that are more closely matched to the real world.
From the hospital perspective, those taking advantage of EHR2EDC technology will only stand to gain. By removing the painful task of manual data entry, sites will immediately become more efficient, attractive and competitive places to conduct research. The end result will be increased ability to conduct larger numbers of studies and introduce wider variety to the studies they take part in, including opening up capacity for studies that would otherwise not have taken place. And, as using this technology will increase focus on data quality, a virtuous circle will result, with increased quality and increased quantities of data available for automatic transfer feeding off each other.
Finally, transitioning from siloed, manually duplicated data entry into streamlined data collection from EHR records will reduce the current gap between care and research, and enable clinical trials to become treatment options with direct benefit to patients.
Critical to the successful cross-industry scaling of this technology will be:
The potential for a paradigm shift in how we conduct clinical trials has already been proven. The time for separation of the worlds of healthcare and clinical trials is over. What is needed now is collaborative action between the healthcare and research communities to bridge the gap between the two worlds, for the benefit of patients.
We believe that the use of hybrid studies (where eSource capability is introduced for a proportion of the collected data) and a stepwise approach will be the key to accelerating the unlocking of the full potential of EHR2EDC technology. A few years ago, we all agreed that electric cars were the future. We have since witnessed widespread adoption of hybrid cars, which has, in turn, opened the floodgates to the advances needed to achieve the ultimate vision of efficient fully electric cars. Similarly, our industry cannot wait for 100% readiness to switch on the lights of EHR2EDC technology.
And we are, in fact, already in a position where we can see huge benefits from using the power of this technology in many settings. Even if only 10% of sites involved in a typical oncology study deployed EHR2EDC technology, with the remainder using more traditional methods, significant gains will be seen across all stakeholders. If the technology was used to transfer a limited set of 30% of structured data points in a study, think of the benefits all stakeholders would see from reduction in errors, time, and cost. The unmissable opportunity for all players in the clinical trials space cannot be overstated, so the time for sitting on the sidelines of this revolution really is over.
The path forward should be focused on pre-competitive collaboration with vendors, hospitals, pharma and regulators to create the first 100-strong EHR2EDC-ready hospital network across therapeutic areas. This will truly demonstrate how we can transform the way we do clinical trials.
