TriNetX

TriNetX is a self-service web-based data exploration tool which helps clinical researchers to define a patient cohort using inclusion and exclusion criteria and to explore cohort attributes.

 

TriNetX is populated with data from Epic which have been cleaned, curated and more fully mapped to codes like LOINC to improve data quality and analysis. The date range of data in TriNetX is from July 2016 – present in order to reduce the problem of unexpected gaps in the data prior to the Johns Hopkins Medicine Epic enterprise go-live.

Some investigators may already be using Epic SlicerDicer to explore patient cohorts. While similar in concept, TriNetX and SlicerDicer have different strengths and weaknesses.

  1. Complete the request form and send to Diana Gumas at dgumas1@jhmi.edu. You will be contacted within 2-3 business days.

TriNetX Request Form

TriNetX offers the ability to request a patient-level data download for either Johns Hopkins patients or for patients across multiple healthcare institutions using the TriNetX Research Network. 

To request a data set (medical record number and name) for Johns Hopkins patients

  1. Create a new study (query) in TriNetX. We recommend using Summary Statistics and Design Assistance features to analyze criteria and validate your cohort.
  1. Seek IRB approval to receive the desired data. Confirm that your query matches what was approved by the IRB or request a Change in Research to update your protocol to indicate use of the TriNetX Research Network as the data source. View a sample of the protocol language.
  1. Once your IRB protocol is approved, submit a request to the CCDA.  Include the IRB number for your protocol in the request. The CCDA manager will schedule a brief consult with you, write a specification document, and review the IRB protocol to ensure that the query aligns with IRB approval.
  1. The CCDA manager will then download the patient identifiers (patient MRN, patient name) and deliver the patient list to the study team’s SAFE desktop folder.

 

The CCDA offers two hours of complimentary service, subsidized by the ICTR, after which an hourly rate of $118 is charged. Services include IRB review and specification development, all communications between CCDA and study team members, data download, and data delivery. Most requests can be fulfilled within the 2 hours. 

  1. Create a new study (query) in TriNetX. We recommend using Summary Statistics and Design Assistance features to analyze criteria and validate your cohort.
  1. Contact TriNetX by emailing JHM’s contact, Rich Lilienthal. TriNetX will follow up with the study team to discuss the purpose of the data request and ask about study funding. For datasets requested using Research Network data which are being used for a grant, TriNetX will ask study teams to include costs for the data in the grant. Costs vary from free for most non-grant related use to high depending on use and grant funding. The investigator must negotiate the costs with TriNetX.  Retain the email from TriNetX that indicates whether or not your study will need to pay TriNetX. If you will need to pay TriNetX, they should provide you with a TriNetX Dataset Order Form with negotiated cost and terms.
  1. Seek IRB approval to receive the desired data. Confirm that your query matches what was approved by the IRB or request a Change in Research to update your protocol to indicate use of the TriNetX Research Network as the data source. View a sample of the protocol language.

The CCDA manager will schedule a brief consult with you, write a specification document, and review the IRB protocol to ensure that the query aligns with IRB approval.
  1. The CCDA manager will submit a download request to TriNetX on behalf of the study team. TriNetX will create the dataset and make the dataset available to the CCDA.CCDA will then download the data and deliver to the study team’s SAFE desktop folder.
