-
Interoperability and Standardization: Another challenge that researchers face is related to interoperability and standardization (not uncommon to RWE research). The MHS is characterized by a diversity of data sources, including electronic health records (EHRs), administrative data, and operational deployment records. This diversity presents significant hurdles in data standardization and interoperability, making it difficult to achieve a cohesive and unified view of health data across different platforms and formats.
Overcoming these Challenges
Addressing the unique challenges of conducting large-scale research within the Military Health System (MHS) necessitates innovative approaches to data management, privacy, and analysis. The implementation of data standardization techniques, the use of Common Data Models (CDMs), tokenization strategies, and the execution of network studies emerge as pivotal elements in overcoming these obstacles. Here’s how these strategies can be effectively applied:
Data Standardization and the Use of Common Data Models (CDMs):
-
Foundation for Interoperability: Data standardization through CDMs such as the Observational Medical Outcomes Partnership (OMOP) model provides a structured and consistent format for health data. This uniformity is crucial for combining data from diverse sources within the MHS, including electronic health records (EHRs), administrative data, and operational deployment records, thereby addressing the challenge of interoperability and ensuring a cohesive view of health data.
-
Facilitating Complex Analyses: The standardization of data allows for the integration of military-specific information, such as ranks and deployment histories, into research datasets. By mapping these unique elements within a CDM, researchers can conduct sophisticated analyses that account for the nuanced implications of military service on health outcomes.
Tokenization for Enhancing Data Privacy:
- Safeguarding Sensitive Information: Tokenization can be employed to protect the privacy of service members' information. This process involves substituting sensitive data elements with non-sensitive equivalents, or tokens, ensuring that personal and operational data are not exposed. Unlike encryption, which can be reversed with a key, or general anonymization, which might still allow for re-identification in certain contexts, tokenization ensures that the original data cannot be retrieved without access to the tokenization system. This method aligns with the stringent data privacy measures required within the MHS, enabling researchers to navigate the sensitive nature of military operations while maintaining data utility.
- Compliance with Regulations: By anonymizing identifiable information, tokenization helps research activities within the MHS to comply with specific regulations governing the use and disclosure of health information. This approach facilitates ethical research practices, balancing the advancement of scientific inquiry with the protection of service members' privacy.
Enhanced Collaboration through Federated Network Models:
The utilization of federated network models represents a paradigm shift in how research collaborations are conducted within the MHS. This approach prioritizes the sharing of analytical methods and algorithms over direct data exchange, addressing the critical need for data privacy and security while enabling substantial research partnerships.
- Enabling Secure Collaborations: In a federated network model, external researchers can collaborate with their counterparts in the MHS without the need for direct access to sensitive military health data. By sharing code rather than data, this model ensures that the integrity and confidentiality of service members' information are preserved, adhering to the stringent privacy standards required by military regulations.
- Expanding Research Capabilities: This model facilitates a more dynamic and expansive research environment. Researchers can apply sophisticated analytical techniques across multiple datasets without compromising data security.
