Decentralized clinical trials (DCTs) and quality of data

Clinical trial programs generates varied data that needs to be carefully collated and reviewed. Traditionally, this data is collected in the customized Case Report Form (CRF) for a specific clinical study. With digital technology, the paper CRFs are getting replaced by electronic CRFs. Therefore, instead of entering the data on the paper, it is entered using computers to the dedicated and customized Electronic Data Capture system. This interface is an integral part of DCTs. Here data refers to the information collected from participants throughout the course of the clinical trial. Unlike traditional clinical trials, where data collection often occurs at physical study sites, DCTs leverage digital technologies to enable remote data collection. Data in decentralized clinical trials is collected through various digital channels and technologies, promoting flexibility, convenience, and real-time monitoring. Ensuring the quality and integrity of this data is crucial for the success and reliability of the study outcomes.

Key components of data in DCTs includes patient-generated data comprising of Patient-Reported Outcomes (PROs) and wearable device data, Electronic Health Records (EHRs) comprising of health history and medical records, remote laboratory testing results, data collected during virtual visits between participants and healthcare professionals, digital imaging data, medication adherence and compliance data, demographic and baseline data, data related to the study’s primary and secondary objectives, adverse events and safety data, and informed consent data.

Assessing the quality of data in decentralized clinical trials involves evaluating various aspects to ensure reliability, accuracy, and integrity. Here are some key considerations:

  1. Data Accuracy:
  • Source Data Verification (SDV): Ensure that data collected remotely aligns with source documents, such as electronic health records or patient diaries.
  • Real-time Data Monitoring: Implement real-time monitoring tools to identify and address data discrepancies promptly.
  1. Patient Engagement:
  • Patient Training and Support: Ensure patients are adequately trained to use any technology or devices required for data collection.
  • Patient Compliance: Monitor and address issues related to patient compliance with data collection protocols.
  1. Data Security and Privacy:
  • Secure Data Transmission: Implement secure channels for transmitting data to maintain confidentiality.
  • Compliance with Regulations: Ensure adherence to data protection regulations, such as HIPAA (Health Insurance Portability and Accountability Act) in the United States or GDPR (General Data Protection Regulation)in the European Union.
  1. Technology Reliability:
  • System Validation: Validate the reliability and functionality of the digital platforms and devices used for data collection.
  • Data Encryption: Implement encryption protocols to protect data during transmission and storage.
  1. Regulatory Compliance:
  • Regulatory Alignment: Ensure that decentralized trial processes and data collection methods comply with regulatory guidelines and standards.
  • Audit Trails: Maintain comprehensive audit trails to track any changes or modifications to the data.
  1. Data Monitoring and Management:
  • Centralized Monitoring: Establish a central monitoring system to oversee data quality across multiple sites.
  • Data Cleaning Protocols: Develop and implement protocols for identifying and addressing data errors or inconsistencies.
  1. Site and Investigator Training:
  • Training Programs: Provide training for investigators and site staff on the use of technology and adherence to data collection protocols.
  • Site Audits: Conduct periodic site audits to assess data collection practices and address any issues.
  1. Adherence to Protocols:
  • Protocol Compliance Checks: Regularly assess whether the decentralized trial is adhering to the study protocol.
  • Protocol Amendments: Implement procedures for managing and documenting protocol amendments.
  1. Data Validation and Quality Control:
  • Data Validation Checks: Implement automated checks for data validation to identify outliers or errors.
  • Quality Control Processes: Establish robust quality control processes to ensure data accuracy and completeness.
  1. Patient-reported Outcomes (PROs):
  • Validation Studies: Validate patient-reported outcomes instruments to ensure their reliability and validity.
  • Patient Training: Provide clear instructions and support for patients reporting outcomes remotely.

Assessing the quality of data in decentralized clinical trials (DCTs) requires a holistic approach that considers technology, patient engagement, regulatory compliance, and data management practices. Regular monitoring, training, and validation processes contribute to maintaining data quality throughout the trial. It requires technical compatibility between various digital interfaces as well as with gadgets, wearables and various software programs are integrated in the clinical study program. It requires reasonable computer literacy and familiarity to use gadgets/ wearables for the end users and those involved in the data entry at various levels.
