  • Demographic and preventive services data from OCHIN safety net clinic networked electronic health record dataset; insurance coverage confirmed through individual links to Medicaid enrollment data (2005–2007). OCHIN originally stood for the Oregon Community Health Information Network; it was renamed just “OCHIN” as clinics in states other than Oregon became OCHIN members.

  • Values provided as n (%). Demographic data from OCHIN Inc. safety net clinic networked electronic health record dataset; insurance coverage confirmed through individual links to Medicaid enrollment data (2005–2007).

  • * P < .0001 (χ2) for an association between insurance continuity and demographic characteristics.

  • P < .001 (χ2) for an association between insurance continuity and demographic characteristics.

  • Mean federal poverty level (FPL) was calculated as the average over all visits in the study period. Values >1000% were considered missing; this was <2% of the visits, and the 5.7% with missing FPL information include these outliers.
