RT Journal A1 Cooper WO, Hickson GB, Gray CL, Ray WA T1 CHanges in continuity of enrollment among high-risk children following implementation of tenncare JF Archives of Pediatrics & Adolescent Medicine JO Archives of Pediatrics & Adolescent Medicine YR 1999 FD November 1 VO 153 IS 11 SP 1145 OP 1149 DO 10.1001/archpedi.153.11.1145 UL http://dx.doi.org/10.1001/archpedi.153.11.1145 AB Background  TennCare, Tennessee's Medicaid managed care program, was introduced in 1994 with the goals of controlling spending and of improving access to health care.Objective  To assess changes in the continuity of enrollment following the implementation of TennCare for 2 groups: infants in the first year of life (defined as persons aged 0-12 months in this study) and children hospitalized with a chronic health condition (defined as persons aged 0-18 years in this study).Design  Retrospective cohort analysis.Setting and Population  Infants born during 1992 or 1995 to women enrolled in Medicaid or TennCare and 0- to 18-year-old children enrolled in Medicaid or TennCare who were discharged from a hospital during 1992 or 1995 with a chronic health condition.Main Outcome Measures  For infants, failure to enroll an infant in the first 30 days of life or subsequent gaps in enrollment for 7 days or longer during the first year of life. For children hospitalized with a chronic health condition, any gap in enrollment lasting 7 days or longer by 1 year after discharge from a hospital.Results  There was a reduction in the proportion of infants without continuous enrollment in the first year of life following TennCare (19.4% after vs 25.1% before TennCare; odds ratio, 0.69; 95% confidence interval, 0.67-0.72). Improvements in continuity of enrollment for infants occurred despite an increase in the proportion of infants who were not enrolled in TennCare in the first 30 days of life, even though their mother was enrolled at delivery (14.0% after vs 8.0% before TennCare; odds ratio, 1.86; 95% confidence interval, 1.78-1.96). There was a decrease in the proportion of children hospitalized with a chronic health condition who had subsequent gaps in enrollment by 1 year following discharge from a hospital (14.3% after vs 23.3% before TennCare; odds ratio, 0.52; 95% confidence interval, 0.46-0.59).Conclusion  For infants in the first year of life and for children hospitalized with a chronic health condition, implementation of TennCare improved continuity of coverage.
