Key result

Hospital Episode Statistics diagnoses of vascular disease show 93% agreement with general practice records.

  • n=3,187

Why the study?

The reliability of Hospital Episode Statistics diagnostic information for vascular disease in epidemiological studies in England was not well known.

Population

Random samples of about a thousand women from the Million Women Study with and without HES vascular disease diagnoses in England

Comparison

Vascular disease diagnoses in Hospital Episode Statistics versus general practice records

Design

Observational study comparing linked administrative and primary care data

P
Population
3,187 middle-aged women from the Million Women Study in England with and without hospital admission records for vascular disease, evaluated for diagnostic agreement between hospital and general practice records.
O
Outcome
Agreement between Hospital Episode Statistics (HES) diagnosis records and general practice records for vascular disease

Main Result

Absolute Event Rate: 93% vs 97%

Hospital admission data in England (HES) provide reliable diagnostic information for severe vascular diseases, supporting their use in epidemiological analyses.

Limitations

  • General practice information was unavailable for 13% of women with no HES record and 23% of women with a HES record, largely due to mortality differences.
  • Data on uncomplicated diagnoses may have been more likely to be reported.
  • It is unclear to what extent the results apply to men, other age groups in the UK, or other health care settings.
  • Small numbers of non-hospitalised cases make it difficult to give a precise estimate of non-hospitalised vascular disease.

Cite This Study

Wright et al. (2012) conducted an observational in Vascular disease (n=3,187). Hospital Episode Statistics (HES) diagnosis of vascular disease vs. General practice records was evaluated on Agreement between HES diagnosis and general practice records. Hospital Episode Statistics (HES) diagnoses of vascular disease agreed with general practice records in 93% of cases, and 97% of women with no HES diagnosis had no general practice record of vascular disease.
