DATA SET CHANGE NOTICE 15/2001
Reference:
CP11/01 -DG907/02/01 (v1.1)
Subject:
Cervical Screening
Type of Change:
Revision of the NHS Data Dictionary
Effective Date:
1st April 2001
Reason for Change:
Minor amendments required to the data standards to support Central
Returns
Background:
DSCN 29/99/P22 introduced amendments to the data standards to support changes to central
returns KC53 and KC61.
The description of SCREENING TARGET POPULATION was amended to cater for the
changes to KC53. However, the population reported on the return is no longer the target
population but the total population of women for whom the Health Authority is responsible.
In addition, KC61 now requires the number of smears sent to and received from another
laboratory to be counted.
After further review, there were minor amendments required to the NHS data standards. This
paper details the corresponding changes required to NHS data standards.
Summary of Changes:
REQUEST FOR PATHOLOGY INVESTIGATION
SCREENING TARGET POPULATION
CERVICAL CYTOLOGY TARGET AGE GROUP
SCREENING PROGRAMME: TOTAL TARGET

Change entity type description
REQUEST FOR PATHOLOGY INVESTIGATION
A type of SERVICE ORDER.
A request for one or more investigations within a PATHOLOGY SPECIALTY, from a single
sample, or group of related samples, taken from a PERSON REGISTERED FOR HEALTH
CARE or other human or non-human source and sent to a pathology laboratory at one time.
If investigations within more than one PATHOLOGY SPECIALTY are requested from the same
sample a REQUEST FOR PATHOLOGY INVESTIGATION for each PATHOLOGY
SPECIALTY will be recorded accordingly. For central returns a REQUEST FOR
PATHOLOGY INVESTIGATION received but immediately forwarded to another pathology
laboratory should only be recorded by the pathology laboratory that performs the investigations.
Examples of REQUESTS FOR PATHOLOGY INVESTIGATION are as follows:
a. In chemical pathology, each sample of blood accompanied by a REQUEST FOR
PATHOLOGY INVESTIGATION for any number of different serum assays constitutes a
single request
b. In haematology, a REQUEST FOR PATHOLOGY INVESTIGATION on a single sample of
blood from one patient could include a number of tests, for example, a haemoglobin
estimation, differential white cell count and a sickle cell test
c. In histopathology, several pieces of tissue, such as multiple jejunal biopsies or a breast with
associated tissues, whether dissected or not, constitute one REQUEST FOR PATHOLOGY
INVESTIGATION
d. In immunopathology a sample of blood with a request for an auto-antibody screen and
immune complement assays constitutes a single REQUEST FOR PATHOLOGY
INVESTIGATION
e. In microbiology, one or more throat swabs from a patient, requiring identification of the
pathogenic organism with its antibiotic susceptibility, constitutes a single REQUEST FOR
PATHOLOGY INVESTIGATION
Further clarification of the definition of a single REQUEST FOR PATHOLOGY
INVESTIGATION is that a single request can only be associated with a number of samples if
each sample is:
a.
b.
c.
d.
Of the same type
Taken from the patient at the same time, i.e. within a few minutes
Received by a laboratory at the same time, AND
Analysed (has one or more tests performed on it) by the same laboratory

SCREENING TARGET POPULATION
The target population for a screening programme within a particular age group that is of
interest to a SCREENING PROGRAMME at a given date.
For breast cancer screening, this is the number of eligible women resident in the HEALTH

For cervical cytology, this is the population of women for whom the HEALTH AUTHORITY
and its constituent PRIMARY CARE GROUPS are responsible. It includes those women
registered with GENERAL MEDICAL PRACTITIONERS with practices within a PRIMARY
CARE GROUP accountable to the HEALTH AUTHORITY, some of whom may not be resident
within the HEALTH AUTHORITY area. It also includes those women resident within the
HEALTH AUTHORITY's boundary who are not registered with a GMP. It excludes women
who are resident in the area but registered with a GMP within a PRIMARY CARE GROUP
accountable to another HEALTH AUTHORITY.
Attributes of this entity type are:
