On RSIAs, the RiPCORD-iSEREST project states that there are no evaluation studies available on the effect of performing RSIAs (Eenink, 2008).
It does consider it likely, however,
that a RSIA influences the choices that are made and that small changes can have enormous (safety and financial) effects. Regarding finally NSM,
the RiPCORDiSEREST project also states that the use of NSM is so new that no effect studies have been made.
Nevertheless, it does see a great potential in NSM for saving lives.
