Data Quality incidents
Find out about data quality incidents and how they're dealt with 

Data quality incidents are when data needs to be changed or is wrong, for example, if a person has a duplicate record, or they've died.

What does the National Back Office do?

NBO services include: 

  • removes duplicates, confusion and updates changes of identity (for example, in adoption or gender reassignment cases)
  • de-registrations from the NHS
  • unmatching civil registrations  of births and deaths
  • fixing incorrect data items
  • looking after sensitive record cases
  • working with Defence Medical Services (DMS) for patient movements across borders and in and out of DMS care 
  • dealing with Immigration Health Surcharge data for the Home Office

The Demographics and NBO teams also work together more complicated incidents and issues.
