How is a midstream intervention distinguished from an upstream intervention in care delivery models?

• A. Address individual social needs, while upstream interventions address root causes like policy and community conditions
• B. Upstream focuses on individual social needs
• C. Midstream addresses policy changes
• D. They are the same

Answer: (D)

Interventions are categorized by the level at which they influence health determinants. Upstream interventions target broad, structural factors that shape health opportunities—policy, laws, funding, housing, education, and other social conditions that affect entire populations. Midstream interventions work within communities and care settings to change the immediate environment and processes that people interact with daily—things like improving access to primary care, coordinating services, or adding community-based resources that influence how people behave and use health services. So, upstream is about altering the big-picture context, while midstream focuses on the middle layer—the practical, on-the-ground changes within systems and communities that bridge policy and individual health actions. They are not the same, because they operate at different levels and target different determinants.
