Curricular Threads Integrating health disparities science, health system science, and nutrition education into the medical school curriculum.

Curricular threads represent the integration of critical content throughout the entirety of the undergraduate medical school curriculum for topics that are not the primary focus of a particular course or clerkship but are fundamental to the practice of medicine. For example, awareness of social determinants impacting health care delivery and outcomes is material that is not the subject of a single course but is crucial to provide effective care for patients. Given their importance these topics do not merely exist as standalone workshops or lectures, but are woven into the fabric of our entire curriculum.

Content within each thread is developmentally sequenced and incorporated within courses and clerkships throughout the curriculum. The thoughtful sequencing of content and assessment and the transparency of threads provides continuity of subject matter and allows careful monitoring of thread function. 

Thread leaders work closely with the course directors, clerkship directors, curriculum deans, and others to establish the learning objectives, instructional strategies, and assessment methods for their topic across the entire undergraduate medical education curriculum.

Health Disparities Science Thread 

The burden of illness is disproportionately higher in certain groups and communities due to disparities influenced by social determinants of health. The Health Disparities Science thread examines social determinants of health and explores evidence-based strategies for healthcare providers, institutions, and organizations to improve health outcomes using approaches that identify and mitigate factors that may influence clinical decision-making and the delivery of high-quality care. The thread aims to help students navigate their professional development and effectively advocate for their patients and their communities. 

Health System Science Thread 

Health systems science encompasses the principles and practice of improving quality, costs, and outcomes of healthcare delivery for patients and populations within healthcare systems. Domains include patient safety, quality improvement, population health, value, systems-thinking, evidence-based medicine, and clinical informatics. The thread will aim to help prepare students to become physicians who recognize how patients and populations access and receive care in today's complex health care networks.

Nutrition Education Thread

Nutrition is a fundamental component of health and disease prevention, influencing outcomes across the lifespan and within every clinical specialty. The Nutrition Education Thread provides students with evidence‑based knowledge of nutrition science and develops their skills in nutrition assessment, counseling, and the application of dietary principles in patient care. Through longitudinal integration across preclinical courses and clinical clerkships, students explore how nutrition contributes to disease prevention and management in diverse clinical contexts. Learning is supported by interdisciplinary collaboration with registered dietitians, hands‑on culinary medicine activities, and community‑engaged experiences that highlight food access, cultural considerations, and patient‑centered dietary care.
