What is TriNetX?
The University of Maryland Medical System (UMMS) and the University of Maryland Baltimore (UMB) Institute for Clinical & Translational Research (ICTR) have jointly founded a new Clinical Research Data Sub-core to centralize and streamline the provision of UMMS Epic data for clinical research at no or little cost to the researcher.
Before TriNetX, UMB researchers could not determine if a patient population of interest existed within the University of Maryland Medical System (UMMS). Within TriNetX, a researcher can now explore UMMS Epic data for a cohort of interest. Researchers use the TriNetX query building tool to add a disease condition (ICD 10 code), further refining by treatments and value ranges, medication uses, gender, ages, date range, etc. Within TriNetX, the output can only be displayed in aggregate. However, the researcher can take the next step and request the patient level data file related to the query. The request is routed through the UMB ICTR for a consultation with the UMMS Epic data team. Although IRB approval is not needed at the time of the consultation, it is required to receive the data file.
Researchers needing access to Epic data should make TriNetX the FIRST STOP
Below: Example of TriNetX output for query, Diagnosis of osteomyelitis of jaw and/or osteonecrosis of jaw and any antimicrobial treatment and equal to or greater than 18 years of age.
IF THE AGGREGATE OUTPUT INDICATES A RESONABLY SIZED COHORT OF INTEREST and you would like to request the raw data, see Requesting Data in FAQs below for this process. NOTE: IRB Review and Approval is Required before the honest broker will release data to you.
Please see FAQs below for more information and obtaining access. Good News! If you are UMB faculty, you probably already have a TriNetX account; however, before jumping in, take time to check out the training videos below to get familiar with the platform!

Who can access TriNetX?
TriNetX accounts were set up for current UMB faculty as of early 2023. Logging in requires a UMID. We are working towards providing access to non-faculty at UMB. If you are faculty and it appears you do not have an account, or if you are non-UMB faculty, please see below.
. If it appears you do not have an account, please email EDA-Research@umm.edu noting the following:
1. Subject line: "Requesting TriNetX Account
2. Body of email, please include:
Affiliation: faculty, adjunct faculty, UMMS employee without UMB faculty status, resident, fellow, UMB staff, other.
For non-faculty, please describe the purpose of requesting the TriNetX account. For example, will you be assisting faculty with developing a query in TriNetX.
Your credentials and contact information.
Please remember that you will only see de-identified, aggregate data in TriNetX. TriNetX DOES NOT CONTAIN ANY IDENTIFIABLE INFORMATION. After developing your TriNetX query and examining the aggregate data output, you may then consider using the "Request Data" button. This option notifies the UMMS Epic Team and the UMB ICTR that you are interested in seeing record level data. The UMMS Epic Team will have the key to link your TriNetX query with the UMMS Epic data. The UMMS Epic data team will require prior UMB IRB review and approval of all data elements you are requesting. This includes: the purpose; how and where it will be stored; protections; names of individuals who will have access to the data; how and when it will be stored. See the FAQ on requesting data.
- UMMS Epic Data* from 13 facilities (see Date Range of Data tab below for list):
- Patient demographics: age, gender, race, ethnicity
- Encounters: Site of Care, Admit date
- Diagnoses: billed, recorded at encounter
- Lab Results: panels, microbiology
- Medications: ordered, administered, patient-reported
- Procedures: surgical, imaging, rehabilitative, therapeutic
*Currently, UMMS genomics data is not available. UMMS data is patient-level only at this time with very little encounter-level data. Also, imaging data results/comments are not reported in the TriNetX output.
Data have been cleaned, curated, and more fully mapped to improve data quality and analysis. However, a few things you need to consider:
- How Current are the Data?
- UMMS pushes updated data to TriNetX monthly. This is typical for the 70+ HCOs contributing data to TriNetX
- Erroneous Data Output:
- If data pushed to TriNetX from the HCOs has errors - such as extreme high or low values due to sample mislabeling - the TriNetX data will contain those errors as well. TriNetX does not correct erroneous data.. As they do their quality checks, they will notify the institution of errors they discover. It is up to the institution to make corrections, if possible. Corrections will not be appear until the next data push to TriNetX. Best practice is to enter valid ranges to avoid pulling erroneous data.
- Non-numeric Lab Values:
- Most institutions, including UMMS, do not report numeric values for some labs that fall under or exceed a value threshold. Instead, the values are reported as text values, such as < 1.0 or >9.0 (contains less than or greater than signs). Patients with a text value will not appear in your TriNetX query count because the query can only pull numeric values. This means you may miss patients that meet your criteria. If you request an UMMS Epic data pull, discuss how this can be managaged. Identifying the records with text values becomes a manual process.
- Patient Counts:
- UMMS has multiple hospitals. A patient will be included in the count for each, respective institution's count where they have received care. However, for the overall UMMS sum of patients, a patient will be counted only once.
Please remember that you will only see de-identified, aggregate data in TriNetX. TriNetX DOES NOT CONTAIN ANY IDENTIFIABLE INFORMATION. After developing your TriNetX query and examining the aggregate data output, you may then consider using the "Request Data" button. This option notifies the UMMS Epic Team and the UMB ICTR that you are interested in seeing record level data. The UMMS Epic Team will have the key to link your TriNetX query with the UMMS Epic data and will then be able to add variables containing identifiable information to appear in the Epic data pull on the UMMS side. PLEASE NOTE! Before data can be released, you must provided UMB IRB review and approval of all data elements you are requesting. This includes: the purpose; how and where it will be stored; protections; names of individuals who will have access to the data (include them in your IRB team list); how and when it will be stored. Please used IRB template language below.
A. REQUESTING UMMS EPIC DATA
1. On the right panel of your TriNetX query portal, select the yellow "Request Dataset" button, which will notify the UMB ICTR and UMMS/UMB Research Informatics Core (RIC) team. The ICTR will reach out to you about the next steps and application process. The application link can be found in the "How to Apply for ICTR Resources" section HERE at the bottom of the page. In the application, navigate to the Informatics section and select Access to Clinical Data.
After ICTR administrative review, your application will be forwarded to the UMMS Epic data honest broker and team who will schedule a consult with you to discuss your request. PLEASE NOTE! Data cannot be released without IRB review and approval. The approval must match the project title noted in the ICTR Resource Request form.
Recommended IRB language:
We will be using the TriNetX Research Network Database, a web-based tool for research population cohort and feasibility queries that provides access to aggregate data of dozens of academic medical centers and health care organizations. The University of Maryland Medical System (UMMS) is part of this network.
We will perform a search query within the TriNetX portal, designed in consultation with the TriNetX analysts and/or the UMB TriNetX team, using [specify data elements (ICD codes, lab results, etc.)] to identify a cohort of patients meeting the criteria. The information displayed is de-identified aggregate data only. We will send a request to the UMMS Epic data team via the TriNetX "Request Data" feature. This will alert the UMMS Epic data team and the UMB ICTR that we wish to obtain row level data. The UMMS Epic Team will have the key to link our TriNetX query with the UMMS Epic data and will be able to include any identifiable information we need with the Epic data pull at that time.
The dataset will be downloaded as an Excel file in coordination with the UMMS Epic data honest broker and team. The data is downloaded to the University of Maryland Baltimore (UMB) Secure Research Environment (SRE) in the Azure Virtual Desktop (AVD) for our access. The SRE AVD is the required storage platform for UMMS electronic medical record data for research and TriNetX Research Network downloads. The data cannot be moved from this environment without IRB approval and the required approvals, such as Data Use Agreements from the UMB/UMMS campus and with assistance from the RIC team.
B. REQUESTING TRINETX GLOBAL RESEARCH NETWORK PATIENTS LIMITED DATASET
1. Please note that this activity is outside of UMMS/UMB. Select the 'Browse Network' tab, then select the 'Research' option instead of University of Maryland. Also, TriNetX may charge you a fee for this data.
2. Create study (query) in TriNetX. TriNetX recommends using Summary Statistics and Design Assistance features to analyze criteria and validate your cohort.
3. Use the yellow 'Request Data' button on far right. TriNetX will contact you to discuss the purpose of the data request and ask about study funding. TriNetX will ask you to include costs for the data in a grant-related request. 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.
4. Seek IRB approval to receive the desired data UMB Institutional Review Board (IRB). Confirm that your query matches what was approved by the IRB or submit an IRB modification to update your protocol to indicate use of the TriNetX Research Network as the data source.
Suggested IRB language:
We will be using the TriNetX Global Research Network Database, a web-based tool for research population cohort and feasibility queries that provides access to clinical data of dozens of academic medical centers and health care organizations. The University of Maryland Medical System (UMMS) is part of this network.
We will perform a search query within the TriNetX portal, designed in consultation with the TriNetX analysts using [specify data elements (ICD codes, lab results, etc.)] to identify a cohort of patients meeting the criteria. The output is deidentified aggregate data only. To obtain a limited dataset, we will request the data from TriNetX who will follow up with the PI of this protocol to discuss the purpose of the data request. If approved, the UMMS/UMB Research Informatics Core (RIC) honest broker will work with TriNetX to move the limited dataset from TriNetX to the UMB Secure Research Environment (SRE) Azure Virtual Desktop (AVD) for our access. The SRE AVD is the required storage platform for TriNetX Research Network data downloads. The data cannot be moved from this environment without IRB approval and other required approvals, such as Data Use Agreements from the UMB/UMMS campus, and with assistance from the RIC team.
5. Once your IRB protocol is approved, submit a request through the ICTR Resource Request form HERE. Scroll to the Informatics section of the form and select 'Access to Clinical Data". Include the IRB protocol and approval letter for your protocol in the request, and indicate that you are approved to receive data from the TriNetX Global Research Network. The UMMS Epic data honest broker and team will schedule a brief consult with the PI, write a specification document, and review the IRB protocol to ensure that the query aligns with IRB approval.
6. The honest broker will submit a download request to TriNetX on behalf of the PI. TriNetX will create the dataset and make the dataset available to the UMMS Epic data honest broker and team who will download the data and move to the SRE AVD environment.
