The impact of gaps in health insurance coverage on immunization status for young children.
To examine the impact of full-year versus intermittent public and private health insurance coverage on the immunization status of children aged 19-35 months. ⋯ Our findings raise concerns about access to needed immunizations for children with gaps in private health insurance coverage and challenge the prevailing belief that private health insurance represents the gold standard with regard to UTD status for young children.

Comparative StudyAssessing validity of ICD-9-CM and ICD-10 administrative data in recording clinical conditions in a unique dually coded database.
The goal of this study was to assess the validity of the International Classification of Disease, 10th Version (ICD-10) administrative hospital discharge data and to determine whether there were improvements in the validity of coding for clinical conditions compared with ICD-9 Clinical Modification (ICD-9-CM) data. ⋯ The validity of ICD-9-CM and ICD-10 administrative data in recording clinical conditions was generally similar though validity differed between coding versions for some conditions. The implementation of ICD-10 coding has not significantly improved the quality of administrative data relative to ICD-9-CM. Future assessments like this one are needed because the validity of ICD-10 data may get better as coders gain experience with the new coding system.
