DCOL Center for Clinical Research began conducting clinical trials in 2005. We are a dedicated research department within a large, multi-specialty group practice consisting of over 90 physicians. Longview is located in Northeast Texas with a population of about 77,000. However, due to the large number of surrounding towns and communities we draw patients from a total population of about 250,000. Our group practice has an active database of over 140,000 patients. The research department has access to EMR, so we are able to run searches and recruit specific patient populations.

Being a department of Diagnostic Clinic of Longview, we have easy access to other departments such as Radiology, Ultrasound, Imaging, Echocardiograms, and GI procedures. In addition, we use only Central IRBs.

Our group currently has over 140,000 active patient charts and we have been utilizing electronic medical records since 2008. The research department has full access to these electronic medical records which allows us to do a quick search for potential subjects for our trials. It also allows us to give credible and trackable statistics on feasibilities.

Our patient population is relatively research naïve. We service a population of approximately 250,000 since we draw from many of the smaller surrounding towns. Our population is mainly comprised of Caucasion, African American, Hispanic and Asian.


We utilize only Central IRBs
