The Development of Extremely Premature Infants.

BACKGROUND: Until now, there has been no comprehensive long-term study in Germany on the development of extremely premature infants up to school age. METHODS: From October 2004 to September 2008, in the German federal state of Lower Saxony, 437 infants born at a gestational age less than 28 weeks were followed up at the ages of 2 and 5 years, and some at the age of 10 years. The 5-year follow-up data were collated with the peri- and neonatological parameters and compared with the 2- and 10-year follow-up data. RESULTS: The mortality of extremely premature infants was 25.1%. Among the five-year-olds studied, 14.1% showed cognitive impairment and 17.4% had cerebral palsy. 40.4% manifested abnormalities of speech or language, 33.1% had behavioral abnormalities, and 72.5% received therapeutic interventions. Infants in whom severe brain damage was diagnosed by ultrasonography shortly after birth were more likely to develop cerebral palsy (odds ratio [OR] 38.28, 99% confidence interval [12.55; 116.80]) and to have impaired cognitive development (OR 7.36 [2.52; 21.51]). The likelihood of cognitive impairment was also higher among infants whose mothers had a lower level of education (OR 3.83 [1.68; 8.77]). 73.1% (242 out of 331) of the two-year-olds were in the same category of cognitive function at the 5-year follow-up; 82.4% (65 out of 79) of the 5-year-olds were in the same category of cognitive function at the 10-year follow-up. CONCLUSION: Many of these extremely premature infants had developmental disturbances, and many required therapeutic interventions. The risk factors revealed by this study may help identify patients who are in particular need of support, enabling targeted measures to be taken at the earliest possible stage in order to improve their cognitive and motor abilities. Nationwide, standardized follow-up at the age of 5 years would be desirable.

Based on perinatal and neonatal quality assurance programmes, a follow-up project for the high-risk group of extremely preterm infants, unparalleled in Germany, was initiated in the federal state of Lower Saxony in 2004. Here we describe the new approach of examining a comparison group of term infants, which, for the first time, allows a valid interpretation of the collection of area-wide long-term outcome data on preterm children. The prospective long-term outcome project investigates the medical care situation for children born at less than 28 weeks of gestation up to school age. Based on the information obtained about the children's development the quality of health care will be optimised. A standardised examining concept with established development tests at defined follow-up intervals (at the age of 6 months, 2, 5 and 10 years) is used. At the age of five years 75 % of the examined premature children exhibited impairments. In order to better assess remarkable results, a comparison group of term infants (n=305) selected by a matched-pairs method was examined at the age of five using an analogous concept in kindergartens in Lower Saxony. The results were compared with the first two age cohorts of the follow-up-project (n=226) and quality analyses performed. As expected, significant differences have been found in the children's motor, cognitive and linguistic development between the preterm and term infants examined. This fact draws attention to the importance of early support for the majority of extremely premature infants. Feedback on the results given to the medical staff involved allows for the implementation of best practices and quality improvements. Identifying potential for improvement in everyday health care will help to develop specific optimisation measures.

A long-term outcome project for the special high-risk group of extremely preterm (ELBW) infants has been established in the federal state of Lower Saxony, which is unique in Germany. All departments of neonatology and all divisions of paediatric neurology are participating. Since October 2004 children who were born at <28 weeks gestation are examined using a standardised concept at defined follow-up intervals (at the age of 6 months, 2, 5 and 10 years). The aim is to achieve a cross-sectoral improvement of quality in healthcare on the basis of neurodevelopmental outcome parameters (the right therapy for the right child, at the right time). So far 739 extremely preterm infants (81% of the survivors) were examined at the age of six months, 513 ELBW infants (74% of the survivors) at the age of two years, and 99 children (59% of the survivors) at the age of five years. The comparison of the follow-up intervals has demonstrated an increase of children with minor and major impairment, which indicates the importance of the long-term scheme. At the age of five years 27% of the children exhibit normal development, 49% minor impairment and 24% major impairment. Many ELBW infants need therapy. The model of the project can be transferred to other federal states or regions and other high-risk groups.

The concept of the "ZQ In-house Seminars" provided by external trainers/experts pursues the specific aim to enable all healthcare staff members of hospital departments to analyse statistical data--especially from external quality measurements--and to initiate in-hospital measures of quality improvement based on structured team work. The results of an evaluation in Lower Saxony for the period between 2004 and 2008 demonstrate a sustainable increase in outcome quality of care and a strengthening of team and process orientation in clinical care.
