Comparative analysis of developmental outcomes in very preterm infants: BSID-II versus Bayley-III German norms.
<h4>Introduction</h4>After the release of the Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), US norms, an overestimation of outcome was observed. But, the conformity between the Bayley Scales of Infant Development, second edition (BSID-II), and the Bayley-II...

| description | <h4>Introduction</h4>After the release of the Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), US norms, an overestimation of outcome was observed. But, the conformity between the Bayley Scales of Infant Development, second edition (BSID-II), and the Bayley-III German norms is unknown. This retrospective analysis aimed to compare outcomes of very preterm infants tested with BSID-II and Bayley-III German norms.<h4>Methods</h4>Infants born from November 2007 to July 2018 were included. Exclusion criteria were death or missing outcome. Infants underwent testing with either BSID-II until December 2013 or Bayley-III from January 2014 onward, at 12 and/or 24 months. BSID-II Mental Developmental Index (MDI) was compared to Bayley-III cognitive score and a combined Bayley-Score (CB-III) consisting of the cognitive and language composite score. BSID-II Psychomotor Developmental Index (PDI) was compared to Bayley-III motor composite score. Abnormal outcomes were defined as scores <85 (delay) or <70 (impairment).<h4>Results</h4>649 infants were included. At 12 months, the Bayley-III cohort achieved higher scores in all domains compared to the BSID-II cohort (all p<0.05), with lower rates of motor delay in the Bayley-III cohort (p<0.001). At 24 months, only Bayley-III motor composite scores were higher than the BSID-II PDI (p<0.001). Rates of cognitive impairment were higher in the Bayley-III cohort (p = 0.013).<h4>Interpretation</h4>Our findings indicate that the Bayley-III German norms effectively identify children needing interventions, particularly at 24 months corrected age. This supports both clinical application and scientific comparability with the BSID-II. |
