Since 2008, follow-up examinations at 2 years of age with the standardized Bayley II test have become obligatory in Germany for all very low birth weight infants.


We already performed such examinations before 2006. Here, we compared our data and the completeness of our examinations before and after the introduction of the obligatory 2-year follow-up.


From 2004-2007, 372 infants <1500 g or <32 weeks were discharged alive from our center, 19 infants died during their initial hospital stay, 2 after discharge.


271 patients participated in the follow-up examination at age 2 years, with the proportion of participating infants increasing from 64% to 84% after the introduction of obligatory tests. 75% of infants showed a normal development, while 4% had a severe impairment (defined as being blind (1), deaf (1) or having cerebral palsy (6), the CP rate thus being 2%). 49% of infants completed the Bayley test; the mean MDI was 100.3 (SD 10.6). There were no significant qualtitative differences in test results with the introduction of the obligatory test.


The completeness of our follow-up increased over the years. In comparison with international data we found a low rate of severely impaired, deaf or blind VLBW infants.
