The GEMINI Database
The GEMINI study collects administrative and clinical data from participating hospitals.
2.2 billion +
Data are grouped into two main categories: Administrative and Clinical Data
Discharge Abstract Database (DAD) and National Ambulatory Care Reporting System (NACRS): Data reported to Canadian Institute for Health Information (CIHI) which includes administrative and demographic information associated with acute inpatient and emergency department care.
Costs: Costs associated with each hospital encounter.
Room/Bed Transfers: Information about bed, room and unit transfers during each hospital encounter.
Physician: Physician details associated with each hospital encounter.
Laboratory: Tests orders and results from Transfusion Medicine, Biochemistry, Hematology, Immunology and Microbiology.
Imaging: Diagnostic imaging test orders and reports from X-ray, CT, Ultrasound, Vascular Ultrasound, MRI, Nuclear Medicine, Interventional and Echocardiogram.
Pharmacy: Medication orders during the hospital encounter.
Vitals: Electronically captured vital signs.
Why is it important to collect, clean, and standardize data?
Health care organizations collect information from every patient they see. This could include anything from lab results and radiology reports to age, gender, and why and how frequently they’ve been admitted to a hospital. This information is collected as “data” and is analyzed by physicians, health care teams, and hospitals to make important operational and clinical decisions.
Over time, each hospital, and often even each department, has established their own way of collecting, labelling, and organizing their data. As a result, it can be challenging for physicians, care teams, and hospitals to compile their data into a format that is truly informative and effective for making the best and safest decisions for patients.
The GEMINI Data Repository Dictionary is an essential resource for anyone using GEMINI data. This document describes the metadata of all the data tables within GEMINI. Individuals will be granted access to a subset of tables needed to investigate their research question. For any questions or feedback, please contact GEMINI.firstname.lastname@example.org.
