Cohort Query Tools
A: You can search the Mount Sinai Data Warehouse (MSDW) to identify eligible cohorts by using one of our de-identified self-service tools: Leaf, ATLAS, or TriNetX. Each tool has an accompanying tutorial for use. Click here to learn more.
A: The majority of the data provided by the MSDW comes from the Epic (Verona, WI) electronic health record (EHR), which is the primary EHR for the Mount Sinai Health System (MSHS). Epic was implemented as the inpatient EHR at Mount Sinai Hospital (MSH) in late 2011. The MSDW provides researchers access to data on the over 12 million unique patients in the Mount Sinai Health System Epic EHR, of which nearly 5.5 million of these patients have had an encounter. In total there are over 115 million patient encounters recorded in Epic. The majority of the data collected by the MSDW comes from the Epic Clarity and Caboodle databases, as Epic is the primary electronic health record (EHR) across the Mount Sinai Health System (MSHS). The clinical data is extracted from the Epic Caboodle and Clarity databases, transformed to the OMOP Common Data Model (CDM) and is stored in the MSDW2 database. Epic data can be supplemented with other data resources, such as insurance information from MSX and endoscopy data from Provation.
A: The majority of the data provided by the MSDW comes from the Epic (Verona, WI) electronic health record (EHR), which is the primary EHR for the Mount Sinai Health System (MSHS). Epic was implemented as the inpatient EHR at Mount Sinai Hospital (MSH) in late 2011. Subsequently, Epic has been implemented in additional inpatient facilities across the MSHS, including Mount Sinai Queens (2013), Mount Sinai West (2018), Mount Sinai St. Lukes (2018), Mount Sinai Brooklyn (2019) and Mount Sinai Beth Israel (2020).
A: The data in the MSDW is refreshed nightly.
A: MSDW data broadly includes clinical and operational data, specifically patient encounters and associated diagnoses; patient medical, surgical, social, family, and immunization histories; patient assessments; vitals; clinical orders including lab, radiology, pathology, and medications; medication administrations, clinical progress notes; and clinical discharge summaries. A vast majority of this data is drawn from Mount Sinai Health System’s Epic EHR. Our Data Analysts can help you to determine what will work best for your research and ensure your requested data set is accurate and comprehensible.
Also, please see our comprehensive list of data sources for more details here.
A: MSDW contains PHI data, which is accessible with an approved IRB or QI documentation. Researchers requesting data without an IRB will receive de-identified data. The de-identified data set is provided with confirmation that the data have no HIPAA identifiers. Please note that the MSDW team does not offer de-identified health information in free text fields (such as progress notes). Click here to learn more about the de-identified data service.
A: Yes, there is. You can browse here for more information on the data that is available in the MSDW.
A: Data with identifiable information is available with a valid IRB or QI documentation detailing the PHI allowed. When completing a ticket to request MSDW data, include a copy of the valid IRB or QI documentation along with the details of the data request. Click here to submit a ticket. Click here to learn more about the IRB process through the Office of Research Services.
A: If you are searching for de-identified diagnoses, procedures, encounters, labs, medications, vitals, or demographics and review generated visualizations of demographic details, Leaf may be the intuitive self-service tool for you. Leaf offers de-identified data only, and therefore no IRB or QI documentation is required to browse Leaf. Click here to see Leaf’s user tutorial.
If you are searching for Facilities, diagnoses, procedures, medications, labs, orders, and patient demographics using an OMOP-centric standard vocabulary, ATLAS may be the dynamic query tool for you. ATLAS offers de-identified data to all Mount Sinai users, and contains PHI data and custom datamarts for researchers with valid IRB or QI documentation. Click here to see ATLAS’ user tutorial.
If you are searching for Demographics, diagnoses, procedures, medications, labs, vitals, BioMe patients, and Image Research Warehouse patients, TriNetX may be the clinical research query tool for you. Though the global research network can be slow to operate at times, de-identified data and imagery is available to users. Click here to see TriNetX’s user tutorial.
Still unsure which tool is best for you? Click here to see a comparison table.
A: Leaf and ATLAS query MSDW2, which is run by Scientific Computing and Dara. The TriNetX tool queries a third-party database to which Mount Sinai contributes data. The functionality of TriNetX for defining a patient cohort is very similar. To compare data types, advantages, and disadvantages of the three tools, refer to the MSDW Services comparison table.
A: All users need to be connected to the Mount Sinai network with VPN tunnel (or on site) to access these tools. If you are still getting an error message in your browser, please submit a help ticket.
A: Nope! Requesting access to a query tool will establish a user account. Each user must have their own account to access a query tool, and once an account is set up a user can keep using their login credentials to access de-identified data.
For users requesting PHI data, a valid IRB must be submitted with access request. When the IRB expires, a renewed IRB must be submitted to continue accessing approved PHI data. Click here to submit access request.
A: The “Conditions” being queried by both Leaf and ATLAS in MSDW2 are the diagnoses from Epic. These include encounter diagnoses, problem list, hospital problems, past medication history, etc. If the patient has a diagnoses documented in this way, the query tools will pick them up, regardless of whether the patient is getting treatment or not.
A: Custom queries with our analysts are charged at a rate of $180 per hour. A fund number is required to get started. You can open a ticket to request information here. Please sure to budget for this when developing your grant applications.
If you need a cost estimate ahead of time, submit an MSDW Data Request ticket and specify the request as a Cost Estimate Only. The MSDW team will provide a cost estimate and, from there, you may choose to move forward with the data request.
A: Yes, a fund number must be provided for all IRB Approved projects. Quality, process, financial improvement or similar (non-research) projects, are covered by combined Hospital/School support of the Data Warehouse. There is no chargeback to individual requestors for these types of projects. See the MSDW charge back policy here.
A: All IRB project requests should include an IRB approval letter and protocol document. You can learn more about the IRB process through the Office of Research Services here.
A: Turnaround time varies. A standard data request turnaround time is 2-3 weeks. From the time a researcher submits a data request to the point of receiving the requested data set may take anywhere from 1-6 weeks depending on complexity of data, change requests mid-process, and billing/fund processing. Click here to review the Custom Data Set Delivery process and the steps involved.
A: Yes, cost estimates for approved projects will be provided to the user based on the complexity of the request, and the department’s charge back policy. Please note, if project specifications change, the final price may be adjusted.
