Question to the Department of Health and Social Care:

The data requested is provided in the following table.

Count of (a) finished discharge episodes (FDEs)1 with a primary diagnosis2 of pneumonia3, and the number that died in hospital4, 2009-10 to 2013-145 and (b) total cases of invasive pneumococcal disease and case fatality ratio, 2009-10 to 2013-14.

Notes:

*Total cases of laboratory confirmed IPD, England and Wales (excluding cases only confirmed by DNA detection and bronchiolar alveolar lavage (BAL) samples).

**Proportion of cases that were found to have died within seven days of IPD onset (excluding BAL) ascertained by tracing general practitioner registration records.

1A discharge episode is the last episode during a hospital stay (a spell), where the patient is discharged from the hospital or transferred to another hospital. Discharges do not represent the number of patients, as a person may have more than one discharge from hospital within the period.

2The 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.

3 10 codes used to identify pneumonia: Pneumonia - B20.6 HIV disease resulting in Pneumocystis jirovecii pneumonia; J09.X Influenza due to identified avian influenza virus (J09.X was introduced in the ICD-10th edition); J10.0 Influenza with pneumonia, other influenza virus identified; J11.0 Influenza with pneumonia, virus not identified; J12.- Viral pneumonia, not elsewhere classified; J13.X Pneumonia due to Streptococcus pneumonia; J14.X Pneumonia due to Haemophilus influenza; J15.- Bacterial pneumonia, not elsewhere classified; J16.- Pneumonia due to other infectious organisms, not elsewhere classified; J17.-A Pneumonia in diseases classified elsewhere ; J18.- Pneumonia, organism unspecified; J85.1 Abscess of lung with pneumonia P23.- Congenital pneumonia.

4 HES data cannot be used to determine the underlying cause of death of a patient while in hospital. Deaths may be analysed by the main diagnosis for which the patient was being treated but this may not be the underlying cause of death. For example, a patient admitted for a hernia operation (with a primary diagnosis of hernia) may die from an unrelated a heart attack.

5 HES figures are available from 1989-90 onwards. Changes to the figures over time need to be interpreted in the context of improvements in data quality and coverage (particularly in earlier years), improvements in coverage of independent sector activity (particularly from 2006-07) and changes in National Health Service practice. For example, apparent reductions in activity may be due to a number of procedures which may now be undertaken in outpatient settings and so no longer include in admitted patient HES data. Conversely, apparent increases in activity may be due to improved recording of diagnosis or procedure information. HES include activity ending in the year in question and run from April to March, e.g. 2012-13 includes activity ending between 1 April 2012 and 31 March 2013.
