SCOTTISH DIABETES SURVEY 2002
Community Health Index (CHI)
The Community Health Index (CHI) is a unique patient number that enables records and results to be linked to produce a single patient record. Widespread use of the CHI has significant benefits in terms of administrative efficiency and patient safety. The CHI is also essential for the development of clinical management systems.
Because of the importance of CHI, the Monitoring Group in its last report set a target that all areas should aim to achieve at least 90% of records including a CHI number. We report this year that 11 areas reached the target; eight areas achieving over 95%. The overall percentage increasing from 66.6% to 82.4%. The target of 90% remains for 2003.

Postcode
At individual patient level, accurate collection of postcode data is important for ensuring that patients receive their clinic letters. For planning and epidemiological purposes, postcodes are also used to calculate deprivation categories. The Survey found that 88.4% of records include the full postcode, with eight areas achieving over 95%. Disappointingly, these figures are little changed from 2001. Given the importance of postcode, particularly in relation to the calculation deprivation (
see Annex B) the Monitoring Group is suggesting a target for the 2003 Survey that 95% of all records should have a full postcode.

People in poorer areas tend to have more ill-health and less access to health services than people from more affluent areas; for example, socio-economic deprivation in Scotland is associated with an increased prevalence of Type 2 diabetes.
(12, 13) In order to explore these issues it is proposed that submissions for the 2003 Survey should include deprivation categories for the registered diabetic population in comparison to the population as a whole.
