Consultation-Liaison Psychiatry


The adult Consult-Liaison Psychiatry Service is made up of three collaborative and multidisciplinary teams that include attending psychiatrists, attending psychologists, psychiatry second-, third-, and fourth-year residents, medical students, physician assistant students, psychology doctoral interns, advanced practice providers, and licensed clinical social workers.

We offer psychiatric and psychological consultation to the medically ill patients at Parkland Memorial Hospital, UT Southwestern University Hospitals, and the Dallas Veterans Affairs Medical Center (VAMC), and we provide education, emotional support, and assistance with treatment and discharge planning to the primary care medical teams caring for these patients. The Consult-Liaison Psychiatry teams work to ensure positive outcomes for both patients and medical teams. We also work in outpatient clinical settings such as diabetes, hematology-oncology, maternal fetal medicine, integrated internal medicine-psychiatry clinics, and integrated family medicine-psychiatry clinics.

In addition to CL Psychiatry fellows being part of the Consult-Liaison Psychiatry Service, Addiction Psychiatry fellows also train and provide care on the Consult-Liaison Psychiatry Service at Parkland under Kapila Marambage, M.D., who started the comprehensive addictions services at Parkland and was awarded Consultant of the Year by the Hospitalist Service in 2018 for this service.

The Consult-Liaison Service features a weekly conference with a guest speaker every Monday. Although the conference is primarily targeted to those currently rotating on the Consult-Liaison Psychiatry Service at Parkland Memorial Hospital and UT Southwestern University Hospitals, meetings are open to other interested faculty, staff, and students. Residents also have the opportunity to present case conferences with the consulting faculty of their choice, allowing for group discussion of treatment protocols and ethical implications in complex cases.

We offer a monthly Journal Club, as well as daily educational and staffing rounds with the attending faculty. Medical students attend regular teaching rounds and are evaluated on their presentation skills. Psychology interns at Parkland Memorial Hospital attend weekly didactics and receive regular supervision and consultation from attending faculty.

The Consult-Liaison Service has also created the Psychiatry Student Interest Group (PSIG), overseen by faculty leader Lia Thomas, M.D. Since 1981, PSIG has organized events and volunteer opportunities for students at UT Southwestern interested in psychiatry as a topic and career. It aims to increase awareness of psychiatry, introduce students to faculty, and provide an environment for exploration and discussion of the psychiatry field beyond the classroom. PSIG has presented medical students, interns, residents, faculty, and staff with informative and innovative lectures on a variety of topics.

Many CL psychiatry faculty are psychiatry mentors in the UT Southwestern Colleges program and are paired with an Internal Medicine or other primary care physician to meet with a small group of medical students periodically during their first year and a half of medical school to develop interview skills, perform physical and mental status examinations, and explore certain topics such as wellness, cultural medicine, social and spiritual history, and ethics.

Patient Care

Students, residents, and fellows rotating on the Consult-Liaison Services gain exposure to diverse patient populations, reflecting a variety of ethnic, socioeconomic, and cultural backgrounds. Parkland Memorial Hospital is a Dallas county hospital with a complex, multifaceted patient population. Parkland’s position as an internationally renowned center for trauma and burn services also provides trainees with varied and challenging treatment and consultation opportunities. Parkland has psychiatrists working in collaborative care outpatient clinics in diabetes, hematology-oncology, maternal fetal medicine, integrated internal medicine-psychiatry clinics, and integrated family medicine-psychiatry clinics.

UT Southwestern William P. Clements Jr. University Hospital is the inpatient home of the Peter O’Donnell Brain Institute and allows for consultation with neurology colleagues and their patients with complex and often rare neurological conditions.
