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 odds ratios (95% CIs). 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.
