Issues and Known Bugs (persistently important)

TriNetX was created by a third-party company to facilitate patient cohort queries by the pharmaceutical industry. Because there are scores of other healthcare organizations in the TriNetX network, TriNetX provides a federated query for pharmas to simultaneously search across all the member organizations to identify sites for clinical studies. UC is part of this network to attract clinical research from industrial sponsors. An added benefit is we can use TriNetX to search our own patient population using this new tool with features beyond what our legacy i2b2 offered.

User Interface

To access TriNetX, you need a computer with an updated modern web browser and your assigned credentials from the CHI. After you are assigned credentials, be sure to watch the brief video tutorials in the TriNetX Training Center before you begin.

Note: If you are interested in newly incident cases, the date function works well for acute (non-chronic) illnesses such as pneumonia, less so with chronic illnesses such as diabetes or complex diseases. The reason for this is the incidence of such diseases is much harder to index in the system. For example, a new patient may come into the system with diabetes diagnosed years ago, but diabetes is entered into the encounter record or problem list at the time of visit, this clearly does not tell us when the patient was originally diagnosed. From a prevalence standpoint, we can more accurately count how many patients simply have diabetes.

Getting Help

If you feel the query is too complex or are not sure what you want, contact the CHI for assistance.
