Appendix Utah Department of Health Family Health Services Division Methodology for Birth/MMIS Match 1985 to 1989 From the file computer tapes of all Medicaid paid claims, January 1985 through October 1990, we initially selected the "infant" claims, that is, claims with recipient date of birth in the period from 1985 to 1989 with a date of service within the first year of life (N=50,087). Abort 44% of these claims were for inpatient hospital births (DRG 385-391), the remainder hospital and medical claims for procedures performed later in infancy. We attempted to match all the infant claims to Utah Birth certificates for the years from 1985 to 1989, using an iterative matching process based on name, sex, and date of birth information available on both the claim record and the birth certificate. Approximately 92% of the inpatient hospital claims could be linked to Utah resident birth certificates, yielding a birth/MMIS study file of 19,902 cases for the period from 1985 to 1989. About 87% of the claims for procedures later in infancy were linked to birth certificates. The file thus enables analysis of Medicaid birth claims as well as claims in the first year of life for the study cases. 134 NOTES |
