Welcome to the University of Texas Medical Branch Department of Internal Medicine! We are proud to offer advanced medical care, research, and training in the region’s only academic health science center south of Houston.

Our work is shaped by the unique places we practice and the patients for whom we care. Based on Galveston Island and with hospital and clinic locations throughout our mainland communities, our medical practice is diverse in every way – the patients we have the privilege to serve, the illnesses we treat, and the places where we work.

Our vision combines top-notch clinical care with education and research, transforming how we care for patients, teach our students, and expand our knowledge. At UTMB, supported by the Galveston National Laboratory and the nation’s #1 Microbiology department for NIH funding, we create an environment where research and patient care go hand in hand. Through UTMB’s Clinical Translational Sciences Award, we operate a state-of-the-art Clinical Research Center to conduct clinical trials, PI-initiated studies, and industry-sponsored studies that will help shape the future of medicine. Our commitment to innovation drives new solutions, like AI tools that help clinicians practice more efficiently and improve patient care.

UTMB has formed important partnerships that push the boundaries of traditional medicine, making us stronger and more adaptable. We provide essential telehealth care to passengers at sea through our innovative cruise ship medicine program. Our Aerospace Medicine program prepares doctors to deliver care in extreme environments. Our expertise reaches the most remote locations through UTMB’s medical contract with the National Science Foundation in Antarctica. We train and practice in the secure UTMB – Texas Department of Criminal Justice Hospital, the only hospital for care of the incarcerated on a major academic medical center campus.

In a region that has endured many storms, UTMB is an indisputably resilient institution. From our beginnings as a safety-net hospital to our growth into a comprehensive health care system, we have always supported our community through natural disasters, explosions, a pandemic, and more. For prospective faculty, UTMB offers an environment where you can build a fulfilling career and live up to the mission of providing exceptional care to all. Our promise to our patients is this: no matter who you are or what your circumstances, we are dedicated to providing you with the best possible care.

Background

In low-income settings, clinical trial participation may influence participant behavior, including among control groups. Increased access to care and heightened health awareness during trial enrollment could lead to altered behaviors, a phenomenon known as the Hawthorne effect, which may obscure true intervention impacts; however, this effect remains poorly studied in low-income environments. Aim: To conduct a secondary exploratory analysis of healthcare utilization among control participants of a randomized clinical trial (RCT).

Aim

To conduct a secondary exploratory analysis of healthcare utilization among control participants of a randomized clinical trial (RCT).

Methods

We retrospectively analyzed electronic medical records from the control arm (n=26) of an RCT involving low-income Hispanic adults with type 2 diabetes receiving care at a community clinic. Before randomization to a 12-month diabetes education intervention or usual care (control), participants underwent on-site measurements of HbAic, blood pressure, and weight. Healthcare utilization among control participants was compared during the year before and throughout the study, including all types of exposures: provider visits and other services (eg,orders).

Results

Total healthcare utilization was similar between the pre-period (11.9 exposures/year) and the study-period (11.4 exposures/year; P=.93), with no significant changes across visit types. There were no significant differences in fitted mean monthly visits between the pre- and study- periods (P=.93), nor over time (P=.89).

Conclusion

This exploratory study found no evidence of a Hawthorne effect on healtheare utilization among control participants. While this may suggest consistent healthcare behaviors, it may also highlight an important public health concern: individuals in low-income settings may lack the resources to translate increased awareness into health-related action. Larger studies are needed to further elucidate behavioral patterns in low-income populations.
