Context Children from low-income and racial or ethnic minority populations in the U.S. are less likely to have a conventional source of medical care and more likely to develop chronic health problems than are more-affluent and non-Hispanic white children. They are more often chronically stressed, tired, and hungry, and more likely to have impaired vision and hearing—obstacles to lifetime educational achievement and predictors of adult morbidity and premature mortality. If school-based health centers (SBHCs) can overcome educational obstacles and increase receipt of needed medical services in disadvantaged populations, they can advance health equity. Evidence acquisition A systematic literature search was conducted for papers published through July 2014. Using Community Guide systematic review methods, reviewers identified, abstracted, and summarized available evidence of the effectiveness of SBHCs on educational and health-related outcomes. Analyses were conducted in 2014–2015. Evidence synthesis Most of the 46 studies included in the review evaluated onsite clinics serving urban, low-income, and racial or ethnic minority high school students. The presence and use of SBHCs were associated with improved educational (i.e., grade point average, grade promotion, suspension, and non-completion rates) and health-related outcomes (i.e., vaccination and other preventive services, asthma morbidity, emergency department use and hospital admissions, contraceptive use among females, prenatal care, birth weight, illegal substance use, and alcohol consumption). More services and more hours of availability were associated with greater reductions in emergency department overuse. Conclusions Because SBHCs improve educational and health-related outcomes in disadvantaged students, they can be effective in advancing health equity.

SHPPS 2006 suggests that the breadth of school health services can and should be improved, but school districts need policy, legislative, and fiscal support to make this happen. Increasing the percentage of schools with sufficient school nurses is a critical step toward enabling schools to provide more services, but schools also need to enhance collaboration and linkages with community resources if schools are to be able to meet both the health and academic needs of students.

The results of this study demonstrated that school nursing services provided in the Massachusetts ESHS schools were a cost-beneficial investment of public money, warranting careful consideration by policy makers and decision makers when resource allocation decisions are made about school nursing positions.
