Peterborough and Stamford Hospitals NHS Foundation Trust: Strokes

Volume 485: debated on Thursday 18 December 2008

To ask the Secretary of State for Health how many specialist stroke nurses were employed by the Peterborough and Stamford Hospitals NHS Foundation Trust in each year since 2001; and if he will make a statement. (244130)

To ask the Secretary of State for Health how many patients were treated for stroke-related conditions in the Peterborough and Stamford Hospitals NHS Foundation Trust and its predecessor trust in each year since 1997; and if he will make a statement. (244131)

The information requested is not available in the format requested.

Only data on hospital admissions and activity within hospitals are collected and not all incidences of strokes are treated within a hospital setting.

The Department holds information on patients treated in an in-patient setting who have a diagnosis of stroke or late effects of a stroke recorded. Together, these do not cover all stroke-related conditions as there are a huge number of diagnoses a clinician may or may not include as being a result of a late effect of stroke.

Information on the total admissions to hospital in which the patient had a primary diagnosis of stroke and total admissions in which a patient had a secondary diagnosis of sequelae (late effects) of stroke for Peterborough and Stamford NHS Foundation Trust in years 2002-03 to 2006-07 is shown in the following table.

1 Primary diagnosis:

The primary diagnosis is the first of up to 20 (14 from 2002-03 to 2006-07 and seven prior to 2002-03) diagnosis fields in the HES data set and provides the main reason why the patient was admitted to hospital.

Primary Diagnosis of Stroke:

160—Subarachnoid haemorrhage

161—Intracerebral haemorrhage

162—Other nontraumatic intracranial haemorrhage

163—Cerebral infarction

I64—X Stroke, not specified as haemorrhage or infarction.

2Secondary diagnoses:

As well as the primary diagnosis, there are up to 19 (13 from 2002-03 to 2006-07 and six prior to 2002-03) secondary diagnosis fields in HES that show other diagnoses relevant to the episode of care.

Sequelae (late effects) of Stroke:

169.0—Sequelae of subarachnoid haemorrhage

169.1—Sequelae of intracerebral haemorrhage

169.2—Sequelae of other nontraumatic intracranial haemorrhage

169.3—Sequelae of cerebral infarction

169.4—Sequelae of stroke, not specified as haemorrhage or infarction.

Notes:

1. Quality of care:

Data derived from HES cannot be used in isolation to evaluate the quality of care provided by national health service trusts or clinical teams. There are many factors that can affect the outcome of treatment and it is beyond the scope of HES to adequately record and reflect all of these.

2. Ungrossed data:

Figures have not been adjusted for shortfalls in data (i.e. the data are ungrossed).

3. Finished admission episodes:

A finished admission episode is the first period of in-patient care under one consultant within one health care provider. Finished admission episodes are counted against the year in which the admission episode finishes. Admissions do not represent the number of in-patients, as a person may have more than one admission within the year.

4. Data quality:

HES are compiled from data sent by more than 300 NHS trusts and primary care trusts in England. Data is also received from a number of independent sector organisations for activity commissioned by the English NHS. The Information Centre for health and social care liaises closely with these organisations to encourage submission of complete and valid data and seeks to minimise inaccuracies and the effect of missing and invalid data via HES processes. While this brings about improvement over time, some shortcomings remain.

5. Assessing growth through time:

HES figures are available from 1989-90 onwards. The quality and coverage of the data have improved over time. 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.
