A national body to investigate medical accidents in England should be established immediately, MPs say.
The House of Commons Public Administration select committee said the service was needed because of the scale of the problems in the NHS.
The cross-party group of MPs said the current patient safety system was "too complicated" and "took too long".
It comes just weeks after the government announced it was considering setting up such a service.
Ministers conceded such changes may be needed following publication of the Morecambe Bay hospital inquiry into baby deaths.
