School-age outcomes of late preterm infants in New York City.

OBJECTIVE: This study compares school-age outcomes among preterm (PT) (32 0/7-<34 weeks), late PT (LP) (34 0/7-<37 weeks), and full-term (FT) infants to assess cognitive sequelae of LP births. STUDY DESIGN: We obtained linked birth and educational data for all nonanomalous singleton infants born 1994 through 1998 in New York City who had a third-grade standardized test score (n = 215,138). RESULTS: Children delivered LP and PT had 30% and 50% higher adjusted odds of needing special education than those delivered FT (adjusted odds ratio, 1.34; 95% confidence interval, 1.29-1.40; and adjusted odds ratio, 1.53; 95% confidence interval, 1.30-1.69). They also had lower adjusted math and English scores than those delivered FT (math: 7% and 10% of SD, respectively; English: 4% and 6% of SD). A linear association between gestational age and test scores was seen through 39 weeks' gestation. CONCLUSION: There is a significant risk of developmental differences in PT and LP infants compared with FT infants.

Rates of early intervention referral and significant developmental delay, by birthweight and gestational age.

Though correlated, birthweight (BW) and gestational age (GA) have independent effects on cognitive and neurological outcomes. Jurisdictions vary in their inclusion of these two characteristics in their list of established conditions for automatic eligibility for Early Intervention (EI) services, which may lead them to miss important high-risk groups. We evaluated the relationship between BW-GA combinations and both EI referral rates and risk of EI-diagnosed significant developmental delay in a population of New York City (NYC) births. We linked birth certificates of children born in NYC to resident mothers during 1999-2001 and surviving the first 28 days of life (n = 339,522) to EI administrative data. We calculated EI referral rates for various BW-GA categories, and used a logistic model to directly estimate the predicted risk of delay. EI referral rates of over 50% were observed in children born <1,250 g and those born <30 weeks and 1,250-1,499 g. Additionally, more than one in two children born either less than 1,250 g or <30 weeks and 1,250-1,499 g were predicted to be diagnosed with a developmental delay, compared with almost one-tenth among those born >2,500 g and 39+ weeks. A BW threshold of <1,250 g would identify children with the highest risk of delay; GA as an additional criterion would prevent overlooking high-risk children born <30 weeks but at higher birthweights. Physicians should monitor children with high-risk birth characteristics and refer them, if appropriate, for formal evaluation. EI programs may use these findings to guide determination of automatic eligibility criteria.

Missed opportunities for tuberculosis prevention in New York City, 2003.

BACKGROUND: Proper management and prevention can radically decrease the incidence of tuberculosis (TB). To further decrease TB cases in New York City, every opportunity for prevention must be utilized. This study sought to identify patients whose disease could have been prevented and describe missed opportunities for TB prevention. METHODS: Patients diagnosed with TB from April to July, 2003 were identified using the New York City TB registry. Surveillance data, medical records, and patient interviews were used to determine whether patients missed a prevention opportunity or potential for screening. Preventable TB was defined as inappropriate screening of contacts and immigrants, inappropriate treatment of persons with prior TB diagnoses, or those who tested positive for latent TB infection (LTBI) as contacts, immigration, or in community settings. Potentially preventable TB was defined as occurring when those eligible for LTBI screening in community settings were not screened more than 1 year before TB diagnosis. Patients classified as having preventable or potentially preventable TB were grouped as patients with missed opportunities. We calculated the odds of missing a prevention opportunity using logistic regression. RESULTS: Among the 218 study patients, 22% had preventable TB and 35% had potentially preventable TB. The most common missed opportunity among patients with preventable TB was the failure to initiate LTBI treatment. Birth outside of the United States was not associated with missing a prevention opportunity (odds ratio [OR] = 1.31, confidence interval [CI] = 0.71-2.39); however, extended travel outside of the United States increased the odds (OR = 2.51, CI = 1.19-5.69), particularly among non-US-born patients (OR = 3.01, CI = 1.21-8.59). Missed screening opportunities related to pregnancy, employment, or school attendance were encountered by over half of the study patients. CONCLUSIONS: The majority of New York City TB patients in our cohort experienced at least 1 missed opportunity for prevention. Further study is warranted to determine whether LTBI treatment eligibility should be extended to those who travel for extended periods, particularly among the non-US-born patients.
