Smoking Status at Time of Delivery Collection

BAAS reference: R00412

Frequency: Quarterly                            


Background to the collection

The Smoking Status at Time of Delivery (SATOD) collection covers information on the number of women smoking and not smoking at time of delivery (child birth). You are required to submit figures each quarter from the following:

1. Number of maternities

2. Number of women known to be smokers at the time of delivery

3. Number of women known to be non-smokers at the time of delivery 

4. Number of women whose smoking status was not known at the time of delivery

Please note that revisions will not be accepted as part of this collection. Please therefore ensure that data are entered accurately according to the submission dates. 


Validating your data

For the return each CCG is required to submit four figures at the end of each quarter:

  • Number of maternities
  • Number of women known to be smokers at the time of delivery
  • Number of women known to be non-smokers at the time of delivery
  • Number of women whose smoking status was not known at the time of delivery

All four numbers must be submitted as integers. The following validation will be undertaken by the HSCIC Omnibus system on each quarter's submission: 

Number of women known to be smokers at the time of delivery +
Number of women known to be non-smokers at the time of delivery +
Number of women whose smoking status was not known at the time of delivery = Number of maternities

The Omnibus system will not accept a submission that fails this validation. In this situation the CCG will be prompted to amend and re-submit their data until their submission passes this validation.

A second validation will also be undertaken by the Omnibus system. The current data return will be validated and if:

  • number of maternities is +/-15% of an average of the previous 4 quarters
  • number of women known to be smokers at the time of delivery is +/-15% of an average of the previous 4 quarters
  • number of women known to be non-smokers at the time of delivery is +/-15% of an average of the previous 4 quarters
  • number of women whose smoking status was not known is above or equal to 5% of number of maternities

then a warning will appear on submission.

This will either need to be confirmed as correct by selecting a drop down breach reason or amended.

All data will be published with accompanying data quality tables (by CCG) with each data item compared against the average of the previous four quarters' data:

  • percentage change in the number of maternities
  • percentage point change in the percentage of women smoking at time of delivery
  • percentage point change in the percentage of women not smoking at time of delivery
  • percentage point change in the percentage of women with an unknown smoking status

This should maximise the usefulness of the data whilst also encouraging improvements in data quality by highlighting any areas that may have issues. CCGs should aim to keep the percentage of maternities where smoking status is "not known" to below 5 per cent.

You are advised to read the amended guidance to familiarise yourself with the new requirements of the collection
