The National Child Mortality Database (NCMD) will collect information about all children in England who die before their 18th birthday. The Healthcare Quality Improvement Partnership (HQIP) is commissioning this programme of work on behalf of NHS England. The NCMD will drive improvement in the quality of health and social care for children in England to help reduce potentially avoidable deaths. It will collect a minimum dataset from the Child Death Overview Panel (CDOP) reviews of all child deaths in England. The collection, analysis and public reporting of information from all child deaths across England will facilitate learning to reduce preventable child mortality.
