Key Health Indicators
Access to PCT data containing small numbers
Unfortunately due to the possibility of disclosure
by differencing we are unable under ONS's confidentiality protocol
to place PCT-level data containing small numbers on a publicly accessible
website. Therefore, some PCT data is password protected. If you work
for a PCT and wish to access this data please register an account on this website and then contact
to request access to the data.
The aim of this indicator package is to bring together
information on health and factors affecting health in the East Midlands
in one easily accessible place. It can be regarded as a dynamic supplement
to the East Midlands
Health Profile. EMPHO’s intention is to update the package as relevant
new information becomes available.
In most cases, data are presented at Regional, Local Authority, Strategic
Health Authority and Primary Care Trust levels giving a picture, albeit
at a fairly high geographical level, of variations in health across the
East Midlands. There are much larger variations in health between smaller
geographical areas within the region and between different sub-groups
of the population. However, these are outside the scope of this document.
While the main focus is on comparisons between areas there is also
trend information for some indicators where available.
The Key Health Indicators theme is split into three sections:
1. Much of the information in this package is from
Government Departments. HMSO “Click-Use” licences allow the licensee
to re-use the majority of 'core' government information that is subject
to Crown copyright protection.
Licences are free of charge and valid for five years. See HMSO's
website for further information and guidance on the electronic application
2. In line with Government policy on “disclosure” (preventing information
about an individual being identifiable in official statistics) the information
in this package has been screened so that figures based on counts
of less than five have been suppressed (shown as a "-").
3. Population “anomalies” in the Compendium 2002 data. The
Enhanced Compendium released in January 2004 highlights population “anomalies” in
some PCTs. In the East Midlands only two PCTs are significantly affected
by this problem (i.e. where the difference between two methods of population
estimation used in the Compendium is greater than 5%). These are:
• Greater Derby PCT
Central Derby PCT
More information on this can be found on the NCHOD Knowledge base in
2002 letter (Enhanced version) and in their Update
10/2003 which also contains a spreadsheet comparing populations calculated by
both methods for all PCTs.
Compendium errors for Northamptonshire PCTs
The Compendium 2002 made use of definitions for Daventry and South Northamptonshire
PCT and for Northamptonshire Heartlands PCT which were erroneous. Compendium
2002 data for Daventry and South Northamptonshire PCT includes some wards
which properly constitute part of Cherwell Vale PCT. Similarly Compendium
2002 data for Northamptonshire Heartlands PCT includes some wards which
actually form part of South Peterborough PCT. The error is compounded
by the fact that in calculating rates the population base that was used
makes use of a different definition for these PCTs.
This problem affects only the PCT-level data presented here where the
source is the Compendium 2002. Only the two Northamptonshire PCTs mentioned
above are affected.
NCHOD have informed us that the Compendium 2002 indicators will not
be revised, and that the major effort will be employed in producing an
accurate Compendium 2003 release.
Census errors for West Lincolnshire PCT
Census 2001 erroneously included several Output Areas within West Lincolnshire
PCT. This results in a population overcount for West Lincolnshire PCT
whereby West Lincolnshire has some 4,400 more households and 10,800 more
people out of a total of 96,092 households and 229,596 people which should
have been assigned to other PCTs not in East Midlands. This is the only
PCT affected. LA counts are not affected. ONS indicate that a correction
will be released in 2004. For details of the Output Areas involved see http://www.statistics.gov.uk/census2001/ks_ha_corrections.asp
All data in this Key Health Indicators package which are derived from
Census 2001 will therefore reflect a population for West Lincolnshire
PCT which is about 4% too high.
