Partnering on the Social Determinants of Health With the Community Health Improvement Matrix.

The research goal was to describe local health department community health improvement plans and hospital implementation strategies, assessing the extent to which they address the social determinants of health. In 2014, we used a grounded theory approach to conceptualize the extent of social determinant efforts in a purposive sample of improvement plans and implementation strategies (N = 12) taken from the community health assessment database pilot project (N = 502). We developed the Community Health Improvement Matrix (CHIM), categorizing public health activities according to target and prevention levels. In 2016, we surveyed NACCHO's Performance Improvement Workgroup (N = 9) using CHIM categories. In 2017, we tested the interrater reliability of the CHIM through an analysis of stories in 30 states (N = 101). We shared the CHIM in conferences, trainings, and focused conversations. The CHIM provides a framework for local public health partners to work together to address social determinants.
