Data is to be extracted from the source WelshPAS system instance for each Local Health Board. There will be a requirement that traditional DSCN data feed methods will have to continue for some Health Boards where non-WelshPAS systems or multiple PAS systems are in place and these will either be provided through a CSV file format or a SQL-to-SQL transfer. In both instances, the data will be transported into the NDR controlled data stores for dissemination.
