Health Informatics

Using data analysis to improve research, patient care and clinical outcomes

A tremendous amount of electronic data is available to improve children's health care and influence lifetime health. The Johns Hopkins All Children’s Health Informatics Core brings innovation in using electronic health data to provide high quality care—from achieving the best outcomes to ensuring the highest level of patient safety and lowering the cost of care.

The Health Informatics Core provides the tools and knowledge to use data more effectively institution-wide in real-time clinical decision-making, pediatric research and other operational decisions that can enhance patient care. Experts in research methods, database design and integration, epidemiology, biostatistics and predictive analytics provide meaningful data and analysis that improve care and increase understanding of pediatric illnesses.

Multidisciplinary collaboration is integral to the efforts of the Health Informatics Core. Our team works closely with researchers and clinicians to use data-driven information to better understand the underlying causes and mechanisms of diseases, as well as to predict or determine effective treatments in specific patient populations—the essence of precision medicine.

The work of the Health Informatics team enhances patient care in real-time—from something as simple as creating an alert to remind the medical team to redose a child with antibiotics during a 12-hour surgery or as complex as shaping guidelines that eliminate costly blood typing and matching for patients who don’t need it.

The Health Informatics team also works closely with Decision Support (Finance Division) and Information Technology leadership to continually develop the enterprise Data Warehouse and initiatives that enhance value-based care.

Clinical Database Registries 

Because clinical and outcomes data are essential to the core’s mission and scope, the Health Informatics Core provides dedicated Clinical Database Registry Administrators for several existing databases and outcome registries. These registries include:

  • VPS—Virtual PICU Systems (critical care)
  • VON—Vermont Oxford Network (neonatology)
  • CHNC—Children’s Hospitals Neonatal Consortium (neonatology)
  • NSQIP—American College of Surgeons National Surgical Quality Improvement Program—Pediatric  (surgery)
  • STS—Society of Thoracic Surgeons (cardiology)
  • PHTS—Pediatric Heart Transplant Society (cardiology)
  • IMPACT—National Cardiovascular Data Registry (cardiology)
  • CRStar—Cancer Registry (hematology/oncology)

Epidemiology and Biostatistics 

The epidemiology and biostatistics teams within the Johns Hopkins All Children's Health Informatics Core provides collaboration and consultation services on study design and data analysis to the hospital's investigators and their collaborators.

We assist investigators at each stage of a study’s lifecycle, including refining the research question, study design, mid-study evaluation and the analysis, interpretation and reporting of results. Services are matched to the needs of each investigator and duration, from long-term collaboration to routine service support to enhance the research efforts of investigators.

Biostatistics services are also available for quality improvement and operational needs and projects. The biostatistics team provides analytic services for all areas across the organization.

Database Design and Data Management

The Database Design and Data Management team provides collaboration and consultation services on database design and data management to assist investigators and stakeholders at Johns Hopkins All Children’s Hospital and their collaborators.

The primary objective of the Database Design and Data Management team is to assist in the design of data collection tools, design and build of database architecture, query and report design and execution, and ongoing data management assistance throughout the life of a research study, operational endeavor or quality improvement initiative.

The Database Design and Data Management team provides support for the use of electronic survey tools such as Qualtrics and also serves as the administrators for the use of REDCap at Johns Hopkins All Children's.

Specific types of support include, but are not limited to:

  • Database design: Creation of the database and corresponding web-based case report forms (CRFs) according to the Institutional Review Board (IRB)-approved or other protocol specifications regarding confidentiality and protected health information, with appropriate enforcement of data security through the implementation of user-based accounts and permissions.
  • Survey design: Electronic platforms for survey distribution and deployment, as well as assistance with survey design to reduce response bias and ensure valid results.
  • Database management: Electronic storage, governance, and oversight for databases that are required for research or quality improvement studies.
  • REDCap design and implementation: The primary electronic data capture platform supported by the team is REDCap, a secure web application designed by Vanderbilt University specifically for data capture of research studies and operational or quality improvement endeavors. Qualtrics is also supported for direct electronic surveying, where needed.
  • User support and training: User training at the outset of the study and support on a continuing basis, as needed.

Clinical Data Warehouse Extracts

A team of Analytic Specialists within the Health Informatics Core provide expertise on sourcing, extracting and formatting clinical data from the Johns Hopkins All Children's Data Warehouse and other clinically-focused data repositories. The team gathers, consolidates, and analyzes data for use in clinically-oriented research, quality improvement projects and operational processes.
 
Information housed in the Data Warehouse also supports Johns Hopkins All Children’s population health initiatives to improve the health of all children, through the analysis of data related to the influence of genes, environment and treatment options for common child health problems like prematurity, asthma and obesity.
 
The Data Warehouse team adheres to strict quality control and privacy and security standards to maintain the validity of all member-related data. 

Predictive Analytics

The Predictive Analytics team fosters enhanced collaborations with groups throughout Johns Hopkins All Children’s, including the Johns Hopkins All Children’s Institutes. The team is focused on the advancement of machine learning and predictive analytics at Johns Hopkins All Children’s.

In just 24 hours, a patient’s electronic medical record grows quickly—with everything from vital signs and lab results, to medication schedules and physicians’ notes. An algorithm can be constructed to more quickly and efficiently analyze retrospective data aggregated into large databases or real-time data during a patient’s care, to identify trends and patterns for determining the best course of treatment and increase the likelihood of postive outcomes.

Visual analytics—the science of displaying information from large data sets in a compressible manner—is then used to sort large amounts of data to identify the subsections most important to the patient, department or research study.
