Abstract:
Typically, chemotherapy selection takes into account patient demographic data, including disease symptoms, family history, environmental factors and concurrent medications. Although validated and approved genomics tests are available for targeted therapeutics, a major challenge facing healthcare is the ability to process the genomic data in the patient's context and to return clinically interpretable dosing guidance to the physician in a realistic time frame. Delivery of these targeted therapeutics, made possible by clinical decision support systems connected to an electronic health record may help drive both the acceptance and adaptation of an electronic health record system, as well as provide personalized information at point-of-care, as part of the routine workflow. The realization of targeted therapeutics will depend on the concerted efforts of stakeholder groups as they address political, ethical, socioeconomical and technical challenges to achieve personalized medicine adoption through real-world implementation.
Insights
Integrating genomic data into clinical decisions for chemotherapy is challenging. Clinical decision support systems connected to electronic health records can enable personalized medicine by providing interpretable dosing guidance.
Area of Science:
- Genomic medicine
- Clinical informatics
- Personalized oncology
Background:
- Chemotherapy selection traditionally relies on patient demographics, symptoms, and history.
- Genomics tests for targeted therapeutics are available but face challenges in clinical data integration.
- Processing genomic data within patient context for timely, interpretable dosing guidance is a significant hurdle.
Purpose of the Study:
- To address the challenge of integrating genomic data into clinical decision-making for chemotherapy.
- To explore the role of clinical decision support systems in delivering personalized medicine.
- To facilitate the adoption of electronic health record systems through enhanced point-of-care information delivery.
Main Methods:
- Utilizing clinical decision support systems (CDSS) integrated with electronic health records (EHR).
- Developing methods to process genomic data within the patient's specific context.
- Focusing on generating clinically interpretable dosing guidance for physicians.
Main Results:
- CDSS connected to EHRs can provide personalized information at the point-of-care.
- This integration can improve the acceptance and adaptation of EHR systems.
- The workflow can be enhanced by providing actionable genomic insights during routine patient care.
Conclusions:
- Realizing the potential of targeted therapeutics requires overcoming political, ethical, socioeconomic, and technical challenges.
- Concerted stakeholder efforts are crucial for the widespread adoption of personalized medicine.
- Successful implementation hinges on integrating genomic data effectively into clinical workflows.
