Asthma: Greater London

Volume 487: debated on Tuesday 3 February 2009

To ask the Secretary of State for Health what estimate he has made of the rates of asthma in (a) children aged four years and under, (b) children aged five to 14 years and (c) adults in each London borough per 1,000 population; and if he will make a statement. (253212)

[holding answer 2 February 2009]: Data are not collected in the format requested. Data are collected on the number of people in each practice on the asthma disease register by primary care trust (PCT), and by prevalence. The national Quality and Outcomes Framework (QOF) records the number of people recorded on practice registers; the number of patients on the clinical registers can be used to calculate measures of disease prevalence, expressing the number of patients on each register as a percentage of the number of patients on practices lists. 2007-08 data are contained in ‘PCT level QOF tables’. The following table shows the number of people recorded on asthma registers in 2007-08 from the QOF.

Notes:

1. QOF is the national Quality and Outcomes Framework, introduced as part of the new General Medical Services contract on 1 April 2004.

2. Participation by practices in the QOF is voluntary, though participation rates are very high, with most Personal Medical Services practices also taking part.

3. The published QOF information was derived from the Quality Management Analysis System (QMAS), a national system developed by NHS Connecting for Health.

4. QMAS uses data from general practices to calculate individual practices' QOF achievement. QMAS is a national IT system developed by NHS Connecting for Health to support the QOF.

5. The system calculates practice achievement against national targets. It gives general practices, PCTs and strategic health authorities (SHAs) objective evidence and feedback on the quality of care delivered to patients.

6. The QMAS captures the number of patients on the various disease registers for each practice. The number of patients on the clinical registers can be used to calculate measures of disease prevalence, expressing the number of patients on each register as a percentage of the number of patients on practices' lists.

7. Unadjusted prevalence = (number on disease register/list size) *100. These are raw data.

8. QOF data are collected annually.
