Informatics and Data Science

Doctor with Nurse at Computer

DLS develops, implements, and evaluates informatics and data science approaches to strengthening laboratory information systems for improved clinical and public health outcomes. This collaborative work includes coordination of regional and national systems, reporting of laboratory diagnostic information to electronic health records (EHR), decision-making tools for health care providers, research and application of laboratory-related data, and informatics solutions for improved laboratory management, practice, and emergency preparedness.

Our Services
  • Improve the collection, maintenance, research, and application of data from national laboratory systems and other large health databases, such as medical data warehouses.
  • Provide leadership and coordination for improving the management of laboratory information systems.
  • Support interoperable health IT standards, such as harmonization of laboratory testing codes (e.g., LOINC, SNOMED CT) to enable meaningful comparison of results worldwide.
  • Operate the CDC Biorepository  – The CDC Biorepository preserves CDC’s valuable sample collections, including those from historical studies, outbreak investigations, and emergency responses.
  • In partnership with the genetic testing community, the Genetic Testing Reference Material Program (GeT-RM) develops and provides publicly available, appropriate, and well-characterized genomic DNA reference materials that can be used for quality control, proficiency testing, test development/validation, and research. Use of these materials can help to assure the quality of clinical genetic tests.
  • Collaborate with partners such as the Association of Public Health Laboratories (APHL), to enhance access, analysis, and sharing of information about laboratory services and capacity nationwide through the Public Health Laboratory System Database (PHLSD) and the Informatics Self-Assessment Tool.
Our Impact

  • DLS’ laboratory services are a critical component of health IT. Accurate, expedient, and user-friendly integration of laboratory diagnostic results into EHRs helps ensure quality patient care and treatment.
  • DLS collaborates wtih many partners to provide subject matter expertise and build consensus on topics, such as the development of standardized vocabulary, semantic operability of laboratory test coding, certification of EHR modules, inclusion of Clinical Laboratory Improvement Amendments requirements, and laboratory accreditation standards.
  • The CDC Biorepository samples play crucial and historical roles in public health research and population health. DLS provides a controlled, uniform environment to preserve CDC’s unique samples. The CDC Biorepository supports national studies, such as the National Health and Nutrition Examination Survey, the Active Bacterial Core Surveillance Program, and the Child Health and Mortality Prevention Surveillance Network.
  • DLS has amassed a large inventory of samples to support genetic testing. These reference materials, available through Coriell Institute for Medical Resarch, are used by clinical laboratories, research laboratories, and test developers nationwide to improve the quality and availability of genetic testing and to develop new tests.

  • When fully implemented, the PHLSD will form the basis of a first-ever, online national directory of public health laboratory services. Health departments will be able to immediately direct samples to laboratories that can run the tests needed. The web-based Informatics Self-Assessment Tool provides for the first time, data available on the informatics capacity of public health laboratories nationwide, and a suite of tools for comparison and analysis from the national to organizational level.
  • DLS’ products provide real solutions using current technologies. DLS designed the partial thromboplastin time (PTT) Advisor app, an innovative mobile application that helps clinicians select the right follow-up tests for patients with blood clotting disorders.
Ensuring safety and effectiveness of laboratory data in EHR systems

As reported in the news, “A young woman’s abnormal Pap smear results went undetected for four years because of a usability issue with her physician’s EHR system. Because of a default setting, the system showed the physician the patient’s previously normal laboratory result, and the more recent abnormal result went unnoticed.1

The young woman’s advanced cervical cancer was only detected when she sought treatment for other symptoms that had developed. As a result of the delay in diagnosis and treatment, the young woman had a hysterectomy.
