reporting delay is thus a precondition for valuable prospective monitoring.
Approaches exist for dealing with such reporting delay (see, e.g., Heisterkamp
et al. 2006), but these are currently not available for routine use in surveil-
lance and have also not methodologically been adapted to the CUSUM
context. Finally, the open-source and copyleft approach of the R system and
surveillance is well suited for the EuroMOMO project aim of obtaining a
mortality monitoring system operating in many different countries.
