Heart Diseases: West Midlands

Volume 467: debated on Thursday 22 November 2007

To ask the Secretary of State for Health how many (a) angioplasty and (b) revascularisation procedures were carried out in (i) Stoke, (ii) south Staffordshire, (iii) north Staffordshire, (iv) Telford and Wrekin and (v) Shropshire county primary care trusts in each year since 2003, broken down by type. (165216)

The information requested is shown in the table. The source of the data is the hospital episode statistics (HES) held by the information centre for health and social care (IC). The data are provided for five primary care trusts (PCTs), in their commissioning, rather than provider of treatment role.

Historical information for new PCTs (i.e. pre 1 October 2006) has been calculated by the 1C based on information previously provided by predecessor organisations.

Rather than grouping procedures under the headings ‘angioplasty’ and ‘revascularisation’ the 1C has provided a more detailed break-down of the operative procedures that sit under these headings so there is no confusion as to what has been included and counted. Angioplasty has been classed as those codes between K49-K50 and ‘revascularisation’ has been classed as those codes between K40-K46.

Notes:

All operations count of mentions—These figures represent a count of all mentions of an operative procedure in any of the 12 (four prior to 2002-03) operative procedure fields in the HES data set. Therefore, if a operative procedure is mentioned in more than one operative procedure field during an episode, all operative procedure are counted.

Finished Consultant Episode (FCE)—An FCE is defined as a period of admitted patient care under one consultant within one healthcare provider. Episodes do not represent the number of patients, as a person may have more than one episode of care within the year.

Main operation—The main operation is the first recorded operation in the HES data set and is usually the most resource intensive procedure performed during the episode. It is appropriate to use main operation when looking at admission details, e.g. time waited, but the figures for “all operations count of episodes” give a more complete count of episodes with an operation.

Secondary procedure—As well as the main operative procedure, there are up to 11 (three prior to 2002-03) secondary operation fields in HES that show secondary or additional procedures performed on the patient during the episode of care.

PCT and strategic health authority (SHA) data quality—PCT and SHA data were 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 general practitioner (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.
