[Synchronising school entry health examinations in Lower-Saxony, Germany].

BACKGROUND
In the German federal state of Lower-Saxony the districts are responsible for conducting school entry health examinations. There exist two different standard protocols for diagnosis and documentation, denoted as Weser-Ems (WE) and SOPHIA. In order to analyse and improve the comparability between these two protocols, a working group was established in 2006. One of the objectives was to adjust the protocols in such a way that in the future the collected data will allow for joint health reporting.


METHODS
Each variable was discussed individually by the working group, and if diagnosis or documentation differed between the two protocols, specific modifications were proposed. For certain variables external expert opinions were obtained. For those variables that had to be revised quite generally, specific sub-working groups were established. As prerequisite for implementation, the recommendations of the working group had to be accepted by the user groups through majority votes.


RESULTS
Of 88 (WE) or, respectively, 66 (SOPHIA) variables, 39 (WE) or, respectively, 34 variables initially fulfilled the requirements for a joint analysis. As a result of the working group, for more than 20 other variables the requirements for a joint analysis could be achieved. As soon as the sub-working groups have completed their work, also the issues of physical coordination, cognitive abilities and psychological health will be available for joint analysis.


DISCUSSION
The synchronisation of school entry health examinations in Lower-Saxony is an example of how different protocols of diagnosis and documentation can be adapted to each other to enable joint data analysis without loosing their individual characteristics.
