How It Works

The Discovery Platform brings together data from different
sources for you to analyze.

Epic

Electronic Medical Records, including patient demographics, encounters, notes, labs, flowsheets, and more

REDCap

Research registries

Custom data
sources

Research Access databases spreadsheets

Vendor
Neutral
Archives

Radiology imaging

Physiological monitors

Including critical care units

Note: Additional sources can be requested and added

Data Commons

The Data Commons is a repository that collects patient data from all across Johns Hopkins Medicine. You can think of it as an enterprise data warehouse or data lake.

It currently pulls data from our Electronic Medical Record system, Vendor Neutral Archives (radiology), Hospital Physiological Monitoring, and several research databases (REDcap, Access, SQL and others). We plan to add other sources over time. The data from all those sources is cross-linked and joined into a very wide patient-focused data set.

Subsets of data from the Data Commons can be extracted for your use in research or in patient quality and safety improvement. You can use the Data Catalog to look for tables an * of data you can request.

Data Projections

If you have an approved IRB protocol, you can request a subset of data from the Data Commons. That subset is delivered to you in a Data Projection. Your Data Projection will include a read-only database that houses your IRB-approved data, and a writeable database.

You can access your Data Projection as well as a suite of Analytical Tools through the SAFE Desktop.

You can access your data and the Data Catalog through the SAFE Desktop.

The SAFE Desktop comes installed with several tools for exploration and analysis.

How Do I Use the PMAP?

You can try it out for free now, via the SAFE Desktop following these steps:

When you're ready to use the PMAP for an IRB-approved study:

Decide what data you need, using the Data Catalog
Sign up for PMAP and request your own data projection
If you need access to data that isn't shown in the Data Catalog, request new data to be included in the PMAP
Start development in the SAFE Desktop or in the crunchr analytic tool (Note: crunchr is only available in the SAFE Desktop)

SAFE Desktop Tools

Installed for exploration and analysis, including:

Microsoft SQL Server

Database management system

sas

Statistical analysis

Stata

Statistical software

Statistical Computing

R Studio

Integrated Development Environment

Python

Programming language

PMAP Tools

Access several tools that can handle more computationally intensive workloads
and modern machine learning tools.

crunchr

Collaboration, Jupyter Notebooks

Provides access to Jupyter Notebooks to write and run analytical code right in your browser. You can work on your code with co-investigators.

Data Catalog

Explore Available Data Sets

Data Catalog uses tags to assist with catalog searching, so that users do not need to know exact table and field names in order to find entries of interest. Example tags include: Demographics. Labs, Medication, Vital, Biospecimen.

The Delivery Platform hosts applications used
in your clinic or with patients.

Delivery applications are built to your needs.

We use reusable visualizations and data modules to build clinical decision support tools, patient education tools, and more, and make them available within Epic if appropriate.
