Feasibility Counts

The ICTR Informatics Core provides multiple resources that investigators can use to get feasibility counts for inclusion in grants and other study preparatory activities. Options for getting feasibility counts are:

  1. SlicerDicer – Investigators with access to Epic can use Epic’s SlicerDicer to get rough patient counts.  To find SlicerDicer in Epic, go to the Epic search bar and type in SlicerDicer. IRB approval is needed prior to using these data for recruitment or to conduct your research or publish.  Note that SlicerDicer has the following limitations:
    – not all data in Epic are available for searching in SlicerDicer (most notably text data)
    – patient data collected outside of the Johns Hopkins Epic system will not be available in SlicerDicer with the exception of some historical lab and encounter data. To learn more about SlicerDicer visit http://slicerdicer.johnshopkins.edu/
  1. TriNetX – TriNetX is a new self-service tool which we plan to launch broadly in January 2019. TriNetX has advanced analytic tools and a cleaner set of data then what is available in SlicerDicer. We will update this website once TriNetX is available for use.
  1. Core for Clinical Data Acquisition (CCDA) – When investigators have sophisticated inclusion and exclusion criteria that cannot be satisfied by using SlicerDicer or TriNetX, we recommend that they contact the CCDA for assistance. Investigators receive 2 initial hours of service subsidized by the ICTR, during which we are often able to complete simple feasibility queries.
