What use would a simple 'attended A&E' be in a child's file? Unless a Dx is also included, then it is useless data.
From what I remember of the BP case, there was information sharing going on, however, some professional's input was valued much lower than others by SW. eg CM flagged up concerns, not taken into account by SW, despite CM being funded by SS as P on ARR. It would be nice to think this is no longer the case, but I doubt it.
Glad to see that SS and HS databases now 'talk' to each other, they didn't when I worked at a SW led CMHT, which meant either health or SS notes had to be copied across from one to the other, without a copy/paste facility.
Not 100% sure how this will prevent abuse to be honest. Prevention is about having enough properly trained people identifying and supporting families at risk, how this is done without adequate numbers of HVs is beyond me. Once a child is taken into a hospital A&E for NAI, there tends to have been a fairly long history of abuse and unreported injury, which may or may not have been flagged up.
