To ask the Scottish Executive how many publications have been issued by the Information and Statistics Division (ISD) regarding the NHS in each year since 1999, and, of these, how many indicated that the information within them was not fully comparable with previous years.
Information and Statistics Divisionissues over 30 quarterly or annual national statistics releases and a largenumber of other publications containing health statistics each year, providinginformation on a wide range of topics about the NHS and the health of people inScotland. Most of these releases are published electronically on ISD’s websiteat
www.isdscotland.org.
In accordance with good statistical practice ISDseeks to highlight in each release any changes in the underlying data,organisational changes affecting how the statistics are presented, or changesin the selection of statistics published. Key factors which have changed thestatistics published by ISD since 1999 and in doing so affected comparabilitywith previous years include:
Legislative changes in ophthalmic services in 1999.
Changing service provision in hospitals whereby somesurgical operations/procedures are now carried out in out-patients, wherepreviously they would have involved day case treatment.
Changes in the way waiting lists/times are classifiedand improved coverage in response to the Audit Scotland report on waiting(2002) and my decision to abolish the Deferred Waiting List from April 2003.
Improvements made to the national statistical returnthat collects information on people attending services for drug problems.
There will have been otherminor improvements to definitions since 1999 that might make some figures notstrictly comparable. However, searching through the thousands of pages ofmaterial to quantify this would incur disproportionate cost.
