UCLA Medical Informatics Program: An Overview

Medical informatics is a rapidly growing interdisciplinary field that leverages computational methods to revolutionize healthcare. As medical practice relies more and more on complex data, the ability to effectively manage and transform this data into actionable insights becomes paramount. The Medical Informatics Home Area at UCLA is at the forefront of this transformation, offering comprehensive training programs for graduate students and postdoctoral fellows.

Introduction to Medical Informatics at UCLA

The Medical Informatics Home Area is a key component of the UCLA Graduate Programs in Bioscience (GPB) and collaborates closely with the Bioinformatics Interdepartmental Program. It serves as UCLA’s central hub for interdisciplinary training in biomedical informatics and data science. The program provides a dynamic environment for PhD graduate students who are passionate about integrating engineering, medicine, public health, and other related fields to modernize healthcare through data-driven methods and tools.

With over two decades of experience, Medical & Imaging Informatics (MII) is integral to various biomedical informatics and data science training initiatives at UCLA. The program supports numerous NIH-funded training programs, including long-standing efforts in medical and imaging informatics, as well as newer programs in biomedical data science and informatics.

Admissions and Program Structure

The Medical Informatics Home Area accepts applications each fall for admission to both M.S. and Ph.D. programs. Prospective students are required to complete a "Plans for Graduate Study" page and submit a one-page personal statement. A writing sample is not required; instead, the admissions committee uses the statement of purpose to align applicants' academic and research interests with faculty expertise.

If invited for an on-campus interview, applicants must arrange for their institutions to send official transcripts directly to Bioinformatics. International students whose native language is not English must also submit TOEFL or IELTS results, unless they hold a bachelor's or higher degree from a university in a country where English is the primary language of instruction or have completed at least two years of full-time study at such an institution.

Admission requirements include a baccalaureate degree from an accredited institution, as well as one year each of calculus, linear algebra, chemistry, and physics. While these prerequisites serve as guidelines, exceptional applicants who do not meet all requirements may be admitted and asked to complete remedial coursework during their first year. Applicants with a completed or in-progress M.S. or M.A. degree should possess extensive research experience and publications closely related to bioinformatics.

Curriculum and Training

Coursework in the UCLA Medical Informatics Home Area covers a wide range of foundational and contemporary topics in biomedical informatics, as well as cross-cutting topics in biostatistics and data science. The curriculum emphasizes biomedical and clinical applications and use cases, ensuring that students understand how research can have a significant impact through interdisciplinary team science.

The program trains PhD graduate students from various UCLA departments and programs, including Bioengineering and other fields. Students come from diverse backgrounds, including computational, engineering, biological, clinical, and basic science disciplines. UCLA's innovative training programs offer students unique opportunities for advanced studies in graduate and post-graduate education.

Key Training Programs

Medical & Imaging Informatics (MII): This signature graduate training program, supported since 2002, focuses on new approaches to research using emergent data types. It provides a broad understanding of biomedical informatics and data science, along with cutting-edge computational methods for analysis and clinical decision support.
Biomedical Data Science for Precision Health: This NLM T15 program trains graduate students and postdoctoral fellows at the intersection of computational approaches, biomedical informatics, public health, and precision medicine. It addresses the gap in translating scientific discoveries into precision healthcare solutions, with trainees gaining expertise in clinical informatics, translational bioinformatics, clinical research, and public health informatics.
Learning Health Systems: UCLA’s Clinical and Translational Science Institute TL1 program provides formal training opportunities for individuals interested in learning health systems and the role of data science. Participants take biomedical informatics and data science coursework alongside students from engineering and the Medical Informatics Home Area, fostering a collaborative learning environment.
KUH-Advanced Research Training (KUH-ART): This TL1 program is a comprehensive interdisciplinary training program based in the Los Angeles metropolitan area. It prepares trainees for long-term careers in high-impact research in benign nephrology, urology, and hematology.
AHA iDIVERSE: This American Heart Association program is a collaboration between UCLA, the University of Hawaii, and Washington University. It establishes research projects and training to advance cardiovascular health for all, focusing on improving community and academic awareness of research ethics, demystifying academia, and addressing attitudinal barriers by enhancing clinical trial recruitment.

The Resident Informaticist Program: Cultivating Clinical Informatics Expertise

Recognizing the limited opportunities for physician trainees to gain exposure to clinical informatics, UCLA Health has developed the Resident Informaticist Program. This program introduces physician trainees to clinical informatics and its academic nature, providing opportunities to expand the clinical informatics workforce.

Program Structure and Curriculum

Taught by the UCLA Physician Informaticist (PI) Committee, the program includes a structured curriculum with monthly sessions covering health IT topics and a journal club that highlights the field as an academic discipline. Each RI designs an informatics project to complete during the program, mentored by a PI and supported by a health IT department/EHR technical team member.

The curriculum covers major topics in clinical informatics, with reading materials from an HIT textbook. RIs can participate in EHR build sessions and access an EHR practice environment to develop their skills.

Program Outcomes and Impact

The RI program has seen significant success, with a high application rate and a positive impact on patient care. A substantial proportion of RI projects have resulted in positive changes impacting patient care, provider efficiency and workflow, reporting, or end-user training. The program has also led to abstract presentations at national EHR vendors’ user group meetings and AMIA meetings.

Satisfaction surveys indicate that RIs find the program to be a rewarding experience with educational benefit and value for their training. The mentorship component is particularly valued, and the program has successfully engaged residents and fellows from various departments, fostering collaborative projects.

Addressing Challenges and Ensuring Sustainability

The program has overcome administrative challenges, secured support from hospital and medical school leadership, and established a mechanism to provide financial incentives for participation. Long-term funding from the health system ensures the program's sustainability, covering stipends, textbooks, meeting expenses, and symposium costs.
