A serious case review into the death of four-year-old Daniel Pelka found repeated failures by agencies set up to safeguard children's welfare but concluded nobody could have predicted his death at the hands of an abusive mother her partner.
The Coventry and Warwickshire Partnership NHS Trust has looked at "a number of actions" that it needed to take following the death of four-year-old Daniel Pelka, medical director Dr Sharon Binyon said.
Dr Binyon told ITV News: "We know that the number of health visitors in Coventry was one of the lowest in the country, so we have been working with NHS England.
"Since the time of Daniel's death we have doubled the number of health visitors and they will be trebled by 2015."
The Trust has also implemented a new system "whereby when there is a child in the house and domestic violence is reported then automatic reporting goes to school nurses and health visitors as appropriate, but it's also kept electronically on their records."
Opportunities to protect Daniel Pelka, who was beaten to death by his mother and stepfather, 'were missed' a serious case has revealed.
Daniel Pelka's Serious Case Review is strong on what went wrong, but weak on explaining why it was allowed to happen.
