To ask the Scottish Executive how many babies have been hospitalised with whooping cough in each year since 1990; of these, how many have died as a result of this disease, and what age each baby was at the time of death.
The available information is shown in the table:
Table1. Number1,2 of Babies4 Hospitalised for Whooping Cough3, 1990-2003
| 1990 | 1991 | 1992 | 1993 | 1994 | 1995 | 1996 | 1997 | 1998 | 1999 | 2000 | 2001 | 2002 | 20036 |
Babies | 184 | 110 | 50 | 88 | 111 | 61 | 55 | 166 | 82 | 91 | 55 | 41 | 51 | 24 |
Deaths5 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 0 |
Notes:
1. These statistics are derived from data collected on discharges from non-obstetric and non-psychiatric hospitals (SMR01) in Scotland.
2. The linked data set required for this analysis contain linked SMR01 and Registrar General's death records. All patient records including deaths for each patient are linked together using “probability matching”. The “probability matching” algorithm uses all available identifying information (name, date of birth, postcode, hospital patient reference number etc.) to link the records.
3. Up to six diagnoses (one principal, five secondary) are recorded on the SMR01 and up to four diagnosis (one principal, three secondary) are recorded on RG death records. All diagnostic positions were used for this analysis. The following codes were used from the International Classification of Diseases (ICD) to define whooping cough:
ICD9 033
ICD10 A37
4. In this analysis, a baby is defined as any patient under the age of 12 months.
5. Death figures relate to the number of babies hospitalised for whooping cough who subsequently died as a result of this condition.
6. Data for the calendar year 2003 are considered to be provisional.
