“…If these 2 dates were not available (about 13% of last menstrual period date is missing on birth certificates), this information was imputed from clinical estimate. [27][28][29] A previous study suggested that the last menstrual period from birth certificates and clinical estimates agreed within less than 2 weeks. 30 Continuous use of AEDs was defined as at least 2 consecutive prescriptions for AEDs or totaling more than a 30-day supply.…”

Objective: The study aims were to investigate secular trends in antiepileptic drug (AED) use in women during pregnancy, and to compare the use of first-and second-generation AEDs.Methods: Study participants consisted of female Florida Medicaid beneficiaries, older than 15 years, and pregnant within the time period 1999 to 2009. Fifteen AEDs were categorized into first and second generation of AEDs. Continuous use of AEDs was defined as at least 2 consecutive AED prescriptions totaling more than a 30-day supply. Polytherapy was defined as 2 or more AEDs continuously used for at least 30 overlapping days. Annual prevalence was estimated and compared.

“…For instance, we used gestational age from birth certificates considered as the criterion standard in a validation study of ICD-9-CM gestational age codes, which inadequately identified preterm infants. 24 Nevertheless, there are environmental risk factors for hospitalizations for RSV that could not be operationalized. One unmeasured and unadjusted risk factor, daycare attendance, deserves some discussion.…”

IMPORTANCE It is unknown whether the age threshold (Յ24 months) for preterm infants with chronic lung disease (CLD) to receive immunoprophylaxis for respiratory syncytial virus (RSV) as currently recommended by American Academy of Pediatrics guidelines correctly identified infants at higher risk for hospitalization for RSV. OBJECTIVE To determine the age when the risk of hospitalization for RSV among preterm infants with CLD becomes equivalent to the risk for healthy, 1-month-old term infants who do not qualify for immunoprophylaxis. DESIGN, SETTING, AND PARTICIPANTSA retrospective cohort study was conducted of 1 018 593 healthy term infants and 5181 preterm infants with CLD using Medicaid billing records (Medicaid Analytic eXtract files) from January 1, 1999, to December 31, 2010, linked to Florida and Texas birth and death certificates. EXPOSURES Age-trend discrete time logistic regression models within a survival analysis framework were developed, adjusting for covariates including the use of immunoprophylaxis, to compare the risk of hospitalization of preterm infants (<32 weeks' gestational age) with CLD at 3 through 34 months of age with the risk of hospitalization of term infants (37-41 weeks' gestational age) at 1 month of age. MAIN OUTCOMES AND MEASURESAge at which risk of hospitalization for RSV among preterm infants with CLD equals the risk for healthy term infants at age 1 month. RESULTSThe study cohort included 1 018 593 healthy term infants and 5181 preterm infants with CLD; because patients could reenter the cohort for a second or third season, the total study cohort consisted of 1 880 531 healthy term infant-seasons (926 206 girls and 954 325 boys; mean [SD] age at first season entry, 12.6 [9.6] months) and 8680 CLD infant-seasons (3519 girls and 5161 boys; mean [SD] age at first season entry, 15.1 [9.1] months). Among term infants with siblings, the risk of hospitalization for RSV averaged across all covariate strata was 9.0 (95% CI, 8.4-9.6) per 1000 patient season-months at 1 month of age. The risk of hospitalization for RSV among preterm infants with CLD became similar to that of 1-month-old term infants at an age of 18.5 months (95% CI, 15.6-22.8). CONCLUSIONS AND RELEVANCEThe age threshold at which the risk of hospitalization for RSV among qualifying preterm infants with CLD approximates that of healthy term infants supports the current American Academy of Pediatrics practice guideline recommending RSV prophylaxis until a maximum of 24 months of age.

An algorithm to identify preterm infants in administrative claims data

Abstract: Identification of prematurity based on gestational age ICD-9-CM codes is not sensitive. The prematurity score has superior construct validity and allows more comprehensive identification of preterm infants in the absence of birth certificates.
