Whilst we do not collect figures on the number of people requiring treatment for mesothelioma, we do collect information relating to the number of finished episodes where the primary diagnosis was mesothelioma. This information is provided in the following table, but it should be noted that the figures relate only to admitted patients and do not include any patients who are treated for mesothelioma in accident and emergency but not admitted, patients treated in an outpatient setting, or patients treated in the community.
It should also be noted that Northumberland, Tyne and Wear strategic health authority and County Durham and Tees strategic health authority combined to form the North East strategic health authority in 2006-07.
|Count of finished consultant episodes where the primary diagnosis was mesothelioma( 1) for selected organisations, NHS Hospitals in England, and activity performed in the independent sector in England commissioned by the English NHS (1997-98 to 2006-07)|
|Finished consultant episodes||England|
|South Tyneside PCT (5KG) as PCT of residence||North East strategic health authority|
|Northumberland, Tyne and Wear SHA (Q09) as SHA of residence||County Durham and Tees Valley SHA (Q10) as SHA of residence|
|(1 )The ICD-10 codes used in this analysis were as follows: |
D19 Benign neoplasm of mesothelial tissue
Finished consultant episode (FCE)
An FCE is defined as a period of admitted patient care under one consultant within one healthcare provider. Please note that the figures do not represent the number of patients, as a person may have more than one episode of care within the year.
Figures have not been adjusted for shortfalls in data (i.e. the data are ungrossed).
Diagnosis (primary diagnosis)
The primary diagnosis is the first of up to 14 (seven prior to 2002-03) diagnosis fields in the Hospital Episode Statistics (HES) data set and provides the main reason why the patient was in hospital.
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. 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 outpatient settings and may no longer be accounted in the HES data. This may account for any reductions in activity overtime.
Primary care trust (PCT) and strategic health authority (SHA) data quality
PCT and SHA data was added to historic data-years in the HES database using 2002-03 boundaries, as a one-off exercise in 2004. The quality of the data on PCT of Treatment and SHA of Treatment is poor in 1996-97, 1997-98 and 1998-99, with over a third of all finished episodes having missing values in these years. Data quality of PCT of GP practice and SHA of GP practice in 1997-98 and 1998-99 is also poor, with a high proportion missing values where practices changed or ceased to exist. There is less change in completeness of the residence-based fields over time, where the majority of unknown values are due to missing postcodes on birth episodes. Users of time series analysis including these years need to be aware of these issues in their interpretation of the data.
