Moving Upstream From the Individual to the Community: Addressing Social Determinants of Health.

School nurses are often the primary health professional promoting children's health-and address not just individuals, but communities. This article, featuring the key principle of community/public health, is the first in a series focusing on The Framework for 21st Century School Nursing Practice™ and presents a case study on asthma and air quality issues comparing the more traditional individual approaches to health (labeled downstream and midstream) with population-level approaches (labeled upstream). Through collaboration with key community stakeholders, school nurses can successfully implement policies and programs to address social determinants of health and, in turn, improve the health of the entire community. As we look to advance school nursing and support best practices, concentrating on population-level, upstream approaches align with recommendations outlined in the Framework for 21st Century School Nursing Practice™.
