Administrative data is being used increasingly for research. Researchers need guidance of what measures are valid, and any problems with the data to plan and interpret studies. The literature on the validity of routine psychiatric diagnoses shows variable quality between data sources and between diagnostic categories.
Hospital Episode Statistics (HES) have been produced from hospital admissions in England since 1997. They contain information about where the person was admitted (e.g. under a psychiatric specialty) and diagnosis according to ICD-10 classifications. They are available from NHS Digital. UK Biobank uses HES in England and equivalent datasets in Wales and Scotland for healthcare outcomes.
HES from general hospitals are regularly audited for accuracy, but from psychiatric hospitals they are not, leading to a knowledge gap, which this report aims to address.
