This poster on IRIS networks and community-level outcomes was presented at the American Public Health Association conference on November 10, 2023 in Atlanta, GA.


Developing cross-sector referral networks can be an effective way of addressing community-level health and well-being outcomes. Social network analyses (SNA) were conducted on 44 individual community care networks active between 2018-2022 to derive composite network typology scores using five SNA metrics. Standardized Health Factor data from were matched to each of the 44 networks and their geographical catchment areas. Multiple linear regressions were conducted to test whether the type of network uniquely predicted health factor outcomes while controlling for the age of the network. Results found that more centralized and cohesive community care networks uniquely predicted better than average physical environment and social-economic outcomes. The maturity of the network had contradictory effects on social-economic (positive) and clinical care (negative) outcomes at the community level. These results have practical implications for how to optimize community care networks to achieve population-level outcomes and theoretical implications for typological classification of networks and their relationship to change over time.
