It is essential for investigators to provide robust data security measures such as complying to regulatory requirements such as HIPAA, GDPR as well as educating their patients.
-
Keeping The Metric Data Valid
The fidelity of any clinical trial is often dependent on how clinical trial data points are collected, which in the case of virtual clinical trials is significantly impacted by the reliance on patient self-reports and digital therapeutics devices. It is important to keep repeating the instructions on how participants are to log in and report health readings, including elevated cardiovascular statistics in order to remain in compliance with accurate metric reporting.
-
Digital gaps/ Digital Illiteracy: Technology Ownership and Usage
These include technology gaps and technology fluencies. Alden and Zuniga (2020) point out that some elderly or rural communities do not possess devices or internet connections which can in turn form barriers to participation in virtual trials. This gap can negatively affect demographic diversity since not everyone would be able to take part in the trial.
-
Regulatory Compliance
Virtual clinical trials also confront a hard reality of regulatory compliance: Country laws, for instance, telemedicine laws and data protection, are also asymmetrical resulting in researchers having a hard time complying across jurisdictions. This complexity can be a hurdle when it comes to commencing trials as well as operational processes.
-
Participant Engagement and Retention
While efforts made in keeping participants engaged throughout the trial are critical to success, such focus often presents unique difficulties in a virtual format. New methods need to be executed, such as routine virtual updates, interesting digital materials, and even push alerts via desired mobile applications. If participants are not actively engaged in the study, there are likely to be many who will withdraw from it.
-
Behavioral Resistance
The transition from conventional to remote trials encounters resistance and hesitance from stakeholders due to perceived risks. With the new measures that come with new technology, a lot of sponsors and sites tend to resist when there is no clear information on what it will entail. This is in a way a great hindrance to the effective penetration and adoption of remote trials.
-
Integration of Systems
In virtual trials, the success of the study depends on the effective integration of a large number of technological systems. This is an issue that many institutions face which makes data collection and management a cumbersome task. This, in turn, may increase the burden on participants and compliance issues which will have an impact on the outcome of trials.
-
Remote Monitoring Challenges
The issue of quality of monitoring data in the remote setting is another impediment that needs to be addressed. It is important to ascertain that the systems for remote monitoring used in the trial are credible and can provide the needed data in real time in order to protect the integrity of the trial results.
