Dawn Primarolo: The following tables show the number of deliveries finished consultant episodes (FCEs) by drug dependent mothers by strategic health authority (SHA) region in 2002-03 to 2005-06, and in 2006-07; and the number of deliveries (FCEs) to drug dependent mothers for the same period, broken down by diagnosis code and type of drug used.

|(1 )For all years the total number of cases is higher when looking at the yearly total broken down by drug use compared to the yearly figure broken down by region. This is because there will be several cases where the mother has been diagnosed as using more than one type of drug and those drugs have been recognised. International Classification of Diseases-10 diagnosis code F19.2 Mental and behavioural disorders due to multiple drug use and use of other psychoactive substances is only used when patterns of psychoactive substance-taking are chaotic and indiscriminate or when the contributions of different psychoactive substances are inextricably mixed.|
Coverage and data quality:
The maternity tail data coverage is not as complete as the rest of HES data. There are a number of reasons for the coverage and data quality issues such as:
trusts submitting a significantly higher number of delivery episodes compared to birth episodes;
trusts failing to submit data on the number of birth episodes where they record a high number of delivery episodes;
trusts failing to submit deliverythe reason for this is that approximately 20 trusts have a stand alone maternity system which is not linked to the Patient Administration System;
trusts identifying a high number of maternity beds available, but not recording any information about deliveries or births;
trusts identifying that they have no maternity beds available, but recording a high number of birth and delivery episodes; and
some trusts have space in their maternity system to record nine birth tails, whereas other systems have space for 18. As deliveries, miscarriages and abortions are all recorded in the birth tail, there are cases where nine tails is not enough to record all of the relevant data.
Between 2001-02 and 2005-06, coverage of hospital deliveries was 72.6 per cent. on average, whereas that of home deliveries was 13.6 per cent. on average. The incomplete coverage problem is significantly compounded by the data quality issues outlined above.
Assessing growth through time:
HES figures are available from 1989-90 onwards. During the years that these records have been collected the NHS there have been ongoing improvements in quality and coverage. These improvements in information submitted by the NHS have been particularly marked in the earlier years and need to be borne in mind when analysing time series.
Some of the increase in figures for later years (particularly 2006-07 onwards) may be due to the improvement in the coverage of independent sector activity.
Changes in NHS practice also need to be borne in mind when analysing time series. For example a number of procedures may now be undertaken in out-patient settings and may no longer be accounted in the HES data. This may account for any reductions in activity over time.
Finished Consultant Episode (FCE):
A FCE is defined as a period of admitted patient care under one consultant within one healthcare provider. The figures do not represent the number of patients, as a person may have more than one episode of care within the year.
As well as the primary diagnosis, there are up to 13 (6 prior to 2002-03) secondary diagnosis fields in Hospital Episode Statistics (HES) that show other diagnoses relevant to the episode of care.
ICD-10 code used:
Z37. Outcome of delivery (must always been found in the first secondary position)
All Diagnoses count of episodes:
These figures represent a count of all FCEs where the diagnosis was mentioned in any of the 14 secondary (seven prior to 2002-03) diagnosis fields in a HES record.
ICD-10 diagnosis codes used (and must be accompanied by secondary diagnosis code):
F10.2 Mental and behavioural disorders due to use of alcohol, dependence syndrome;
F11.2 Mental and behavioural disorders due to use of opioids, dependence syndrome;
F12.2 Mental and behavioural disorders due to use of cannabinoids, dependence syndrome;
F13.2 Mental and behavioural disorders due to use of sedatives or hypnotics, dependence syndrome;
F14.2 Mental and behavioural disorders due to use of cocaine, dependence syndrome;
|F15.2 Mental and behavioural disorders due to use of other stimulants, including caffeine, dependence syndrome;|
F16.2 Mental and behavioural disorders due to use of hallucinogens, dependence syndrome;
F17.2 Mental and behavioural disorders due to use of tobacco, dependence syndrome;
F18.2 Mental and behavioural disorders due to use of volatile solvents, dependence syndrome;
F19.2 Mental and behavioural disorders due to multiple drug use and use of other psychoactive substances, dependence syndrome.
The codes indicate addiction to all types of drugs. For example F11.2 Mental and behavioural disorders due to use of Opioids, would include addiction to Heroin and also Opioids found in prescription drugs.
Due to reasons of confidentiality, figures between one and five have been suppressed and replaced with * (an asterisk). Where it was possible to identify numbers from the total due to a single suppressed number in a row or column, an additional smallest number have been suppressed in order to protect patient confidentiality.
Figures have not been adjusted for shortfalls in data (i.e. the data are ungrossed).
