Fellows gain exposure to diverse patient populations, reflecting a variety of ethnic, socioeconomic, and cultural backgrounds at UT Southwestern-affiliated hospitals, including Parkland, William P. Clements Jr. University Hospital, and the Dallas Veterans Affairs Medical Center. The diverse patient population and opportunity to work with and learn from our large psychiatry faculty at these three teaching hospitals are strengths of our program.

• Parkland is a publicly funded, 862-bed county hospital that opened in 2015. Parkland allows trainees to see patients on a variety of medical services and practice liaison care within the context of a large hospital system with a Level 1 Trauma Center, one of the largest civilian burn units in the United States, and one of the busiest obstetrics services in the nation. Fellows will work on the Addiction Psychiatry CL service and have opportunities for buprenorphine waiver training.
  
  Fellows will attend Parkland Institutional Ethics Committee meetings each month while on the Parkland Consult-Liaison rotation and may also participate in an ethics consultation service elective. The Parkland Institutional Ethics Committee meets its consultation mission through a robust clinical ethics consult service, with a volume of 200 consults/year. Fellows are invited to participate in new consults that arise during their rotation on the committee. In order to improve the care delivery to our patients, families and loved ones with behavioral health concerns, fellows may also participate in an ethics consultation service elective for 1-4 weeks during the year. During the elective, fellows will be expected to participate in facilitating ethics consultation services, serving as the primary contact for ethics consults with behavioral health concerns. Fellows will also be expected to work collaboratively with behavioral health team members on the ethics committee to identify interdisciplinary care team members needing support. Jennifer M Wimberly, Medical Director of Clinical Ethics and Resiliency and Theresa Larsen, Advance Practice Service Lead of Consult-Liaison Psychiatry at Parkland Health will serve as points of contact for the rotation and elective.
  
  
• William P. Clements Jr. University Hospital  is a 751-bed university hospital that opened in 2014 and received a major expansion in 2020 as a state-of-the-art facility designed to be patient centered. The hospital is the inpatient home of the Peter O’Donnell Brain Institute and allows for consultation with neurology colleagues and their patients with complex, often rare, neurological conditions. UT Southwestern Transplant Services are based at this hospital, adding to the CL Psychiatry training opportunities, along with consultation to the medical, surgical, and obstetrics services and the Emergency Department. One of our CL psychiatry faculty, Dr. Jonathan deVries, works full-time in the MICU, providing a 1-month rotation for fellows in critical care psychiatry.
  
  
• Dallas Veterans Affairs Medical Center  is a vibrant academic medical center and part of the Veterans Administration (VA) North Texas Health Care System, which is the second largest VA in the US. It provides fellows with specialized CL clinical, research, and educational experiences in the Spinal Cord Injury Center and the Traumatic Brain Injury and Polytrauma centers, in addition to the medical and surgical units, Emergency Department, and Primary Care-Mental Health Integration outpatient clinics.
  
  CL fellows have ambulatory care experiences in integrated/collaborative care in various outpatient clinical settings, such as HIV, Pain, Neuropsychiatry, Oncology, Maternal Fetal Medicine, Transplant, Integrated Internal Medicine-Psychiatry clinics, and integrated Family Medicine-Psychiatry clinics.
  
  CL fellows receive multiple opportunities to enhance their clinical, communication, leadership, and teambuilding skills as they serve a patient population at UT Southwestern that presents from a variety of backgrounds, speaks a variety of languages, and may present with extremely challenging and complicated medical, neurological, psychiatric, and social histories.

Our consultation-liaison (CL) psychiatrists and psychologists care for medically ill patients at Parkland Memorial Hospital, UT Southwestern University Hospitals, and the Dallas Veterans Affairs Medical Center (VAMC).

Parkland

The Parkland Memorial Hospital Consultation Liaison Psychiatry Service is a large service made up of multiple teams to serve Dallas County. On average, the daily number of consults is 10, with each resident and fellow taking 2 new consults per day. The service includes the Triage Team, made up of a postgraduate year 4 resident, a social worker, up to two advanced practice providers, and a psychiatry registered nurse. This team organizes the consults by acuity and complexity and assigns consults to the rest of the teams. The rest of the service includes two teaching teams, often with two residents who can be psychiatry residents, neurology/psychiatry residents, neurology residents, or internal medicine/psychiatry residents. A separate addiction team is composed of an addiction fellow, multiple psychiatry residents, two social workers, and an advanced practice provider. All these teams have medical students and often physician assistant students as learners. Also, a separate psychology team is staffed by three psychologists with multiple psychology interns. The Consultation Liaison Psychiatry Fellow will meet with Dr. Fernandez and Dr. Robinson to develop a personalized schedule based on interest, which can be a combination of experiences. An average work day is 8 am to 5 pm.

CL Psychiatry Fellow Inpatient Work at Parkland

• Addiction: Rotate with Dr. Marambage and the addiction fellows treating substance use disorders and psychiatric comorbidities. On this team, one can gain more confidence treating complicated alcohol withdrawal, starting Suboxone (buprenorphine/naloxone) or methadone, treating stimulant withdrawal, and practicing motivational interviewing.

On this rotation, one can gain experience guiding junior residents in evaluations and treatment of all psychiatric illnesses found on the CL service with evidence-based care, practice giving feedback to junior residents, learn to attest notes, and improve teaching skills for learners at all levels. This is a rotation for a fellow interested in an academic career.

The initial screening identifies risk factors for needing a psychiatric consultation. Secondary screening involves a structured evaluation of the patient to identify if a full psychiatric consultation is needed. This experience is important, as this model of psychiatric care delivery is becoming more common across the country.

The CL fellow joins the weekly multidisciplinary burn meetings and provides the psychiatric consults for the burn trauma team. This rotation is for the fellow with interest in not only Burn Psychiatry but also ICU Psychiatry and who enjoys being part of a multidisciplinary team.

The CL fellow will take the ethics consults that overlap with CL consults and have the opportunity to work with the Chair of the Parkland Ethics Committee on general ethics consults.

CL Psychiatry Fellow Outpatient Work at Parkland

• Psycho-Oncology: Work with Dr. Robinson embedded within the outpatient hematology-oncology clinic treating specific cancer-related and cancer-treatment-related neuropsychiatric symptoms. The CL fellow will work with patients in all stages of illness, from diagnosis to survivorship. This experience also includes a psycho-oncology journal club that the fellow can continue throughout the year.
• Maternal Fetal Medicine: This rotation is an experience for fellows interested in learning not only maternal fetal medicine psychiatry but also another model of collaborative care. The fellow works with Dr. Doty, providing informal and formal consults to the Parkland OB-GYN outpatient clinic.
