- § A simple or 'pragmatic' analysis of the SMR02 flat file was conducted under the direction of ISD staff. This was compared with a more extensive ('comprehensive') trawling of that file, which includes multiple entries for maternal smoking on a few women admitted to maternity units for antenatal care (e.g. due to premature labour or preeclampsia). We concluded that the pragmatic approach provided an adequate estimate of information available.
- Difference between records obtained using pragmatic and comprehensive approach accounted for by:
- •Duplicate records: 94 women with duplicate records counted only once in Comprehensive approach.
- •Missing admission year: 175 records with missing admission year were excluded from Comprehensive approach.
- It is clear that SMR02 does not capture all women who give birth with information at maternity booking. Total births in Scotland for year ending 31st March 2005 was 52721 - Information Services Division and 53849 - General Register Office.
