Ms Walker said the issue was something that could potentially affect NHS patients all over the country, given current regional differences in practice.
The West Yorkshire Integrated Care Board (ICB) previously said it was reviewing the points made by the coroner as a result of the case and would “establish what changes are required in order to prevent similar losses in future”.
Ms Walker added: “You’re relying on someone asking you the same questions again and coming to the same conclusion, which they didn’t for Chloe.
“For Chloe, for us and for any other mums out there we need to try to get it changed – and I don’t see why it wouldn’t be.”
A spokesperson for the Department of Health and Social Care said: “Our deepest sympathies are with Ms Ellis’ family and friends in this tragic case.
“As part of our 10-year health plan we are shifting healthcare from analogue to digital and introducing a new single patient record so health and care professionals will have all of the information they need about a patient in one place.”
Dr Mark Freeman, deputy chief medical officer at the Mid Yorkshire Teaching NHS Trust, which runs Dewsbury and District Hospital, said: “We send our sincere condolences to Chloe’s family and friends and continue to work alongside West Yorkshire ICB as it reviews the issues raised by the coroner.”
