 The analysis will be conducted in 2 stages. In the first stage, indicators of social complexity as assessed by characteristics of the patients geocoded addresses will be tested for significant association with patient level outcomes meeting or not meeting a specific standard of care. These indicators will be assessed in 4 cohorts: 2 cohorts of patients identified in electronic health records of Clinical Research Networks of community health centers, and 2 cohorts of patients insured by Medicaid in 2015 Oregon and Florida Medicaid cohorts. Due to limitations in the available data, some quality indicators can only be evaluated in a subset of the cohorts. The consistency of specific social complexity indicators, referred to as Community Vital Signs CVS, will be evaluated across the cohorts and quality metrics.
