Data Discovery and Query Builder (DDQB)
The Mayo Clinic CTSA offers consulting appointments for Mayo investigators and study team members who need assistance using Data Discovery and Query Builder (DDQB). DDQB is an advanced query tool that allows authorized research users to access clinical and administrative data stored in the Mayo Clinic Life Sciences System (MCLSS), a clinical data warehouse developed through a Mayo/IBM collaboration.
Examples of data in MCLSS include patient demographics (including research authorization), clinical notes, laboratory test results, and hospital and clinical diagnosis data — essentially, it is a "one-stop shop" for investigators and study teams to access aggregate data under Institutional Review Board (IRB)-approved research protocols.
The DDQB intranet site (requires that you be logged in to the Mayo network) offers a much more comprehensive look at DDQB; you are strongly encouraged to read more about DDQB there before proceeding.
Before scheduling a CTSA consultation
Prior to scheduling a DDQB consultation through the CTSA, you must first:
- Have active MCLSS authorization
- Attend an initial DDQB orientation session
- Upon requesting authorization, you will be added to the DDQB training schedule. This initial orientation by DDQB staff will introduce you to the look and feel of the tool, teach you to build a proper query, explain the tool's abilities and limitations, and more.
If after the above steps you need additional assistance with DDQB, make an appointment through the CTSA Service Center.
Scheduling a consultation
Individual appointments with a data retrieval expert from the Department of Health Sciences Research are available through the CTSA. The goal of these one-on-one consultations is to build on the initial orientation (described above) and make you a self-sufficient DDQB user.
Consultations are available in 50-minute slots on Monday mornings at 10 a.m. or 11 a.m., and Thursday afternoons at 1 p.m. and 2 p.m. Schedule an appointment by calling the CTSA Service Center at 507-255-7101. Consultations take place in the main CTSA offices on Plummer 3.
