2.34  In 2014, there was some variation across Local Authorities in England in the proportion of 

women undergoing abortions who had one or more previous abortions (see Table 11d).  

The proportion of women undergoing repeat abortions ranged from 27% in Devon to 49% 

in Croydon. 

 

2.35  This variation across Local Authorities is likely to be due to differences in local practice 



relating to post-abortion contraception advice. 

 

Previous obstetric history  

 

2.36  In 2014, 54% of women undergoing abortions had one or more previous pregnancies that 



resulted in a live or stillbirth, up from 47% in 2004 (See Table 3a.vii).  18% of women had 

a previous pregnancy resulting in a miscarriage or ectopic pregnancy, up from 14% in 

2004, when the information was first collected (See Table 3a.viii).

2.37  Obstetric history, especially for young women is of interest generally and to those working 

to reduce unplanned pregnancies however, data provided on the Abortion Notification form 

is not detailed enough to do further analysis. 

 

Method of abortion  



 

2.38  Different methods may be used to terminate a pregnancy, depending on the duration of 

gestation, and other circumstances relating to the individual woman.  There is one 

principal medical method, involving the use of the abortifacient drug Mifegyne 

(mifepristone, also known as RU486).   

 

2.39  The main surgical methods are:  



 

I. 


vacuum aspiration, recommended at up to 15 weeks gestation  

II. 


dilatation and evacuation (D&E) recommended where gestation is greater than 15 

weeks 


D&E may be used in combination with vacuum aspiration; such cases are recorded in the 

statistics as D&E.  



 

Figure 6: Abortions by method, England and Wales, 2004 to 2014 



 

2.40  Medical abortions accounted for 51% of the total in 2014.  The proportion of medical 

abortions has more than trebled in the last ten years from 20% in 2004 and 2014 is the 

first year where more medical abortions than surgical abortions took place.  There has 

been a continuing upward trend in medical abortions since 1991 when Mifegyne was 

licensed for use in the UK, when only 4% of abortions were undertaken using a medical 



 

18 


procedure (See Table 3a.iv and Table 5).  In 2014, 62% of abortions under nine weeks 

were medical abortions compared with 28% in 2004.  See Figure 6 above.   

 

2.41  The choice of early medical abortion as a method of abortion is likely to have contributed 



to the increase in the overall percentage of abortions performed at under ten weeks 

gestation (60% in 2004 compared with 80% in 2014).   Early medical abortion is less 

invasive than a surgical procedure and does not involve use of anaesthetics. 

 

2.42  The surgical procedure vacuum aspiration was used for 44% of all abortions in 2014; and 



Dilatation and Evacuation (D&E) alone in about 4% (See Table 3a.iv). 

 

2.43  For abortions at 22 weeks or beyond, feticide is recommended by the Royal College of 



Obstetricians and Gynaecologists prior to the evacuation of the uterus to stop the fetal 

heart.  In 2014, of the 1,193 abortions performed at 22 weeks and over, 58% were 

reported as preceded by a feticide and a further 37% were performed by a method 

whereby the fetal heart is stopped as part of the procedure.  4% of abortions at 22 weeks 

or beyond were confirmed as having no feticide.  For the remaining 12 cases, at the time 

of publication, we had not been able to confirm whether feticide had been performed.  See 

Figure 7)

Length of stay in hospital/clinic 

 

2.44  In 2014, 317 women (0.2%) were reported as having duration of stay of one or more nights 



in a hospital or clinic after their abortion.  More than two thirds of these stays were for 

abortions performed at later gestations of 20 weeks and over (See Table C).

Complications  

 

2.45  Complications were reported in 330 cases in 2014, a rate of about one in every 550 



abortions, slightly lower than the rate in 2013 (about one in 800) and 14 per cent lower 

than in 2004 (See Table 8).  

 

2.46  There were no deaths following abortion reported on form HSA4 in 2014.  Deaths related 



to pregnancy and abortion will be published in the MBRRACE-UK: Mothers and Babies: 

Reducing Risk through Audits and Confidential Enquiries across the UK

Selective terminations  

 

2.47  Pregnancies following fertility treatments such as in vitro fertilisation (IVF) may result in 



more than one embryo implanting in the womb.  In such cases, the outcome of the 

pregnancy may be more successful if the number of fetuses is reduced.  This reduction 

usually occurs at about 12 weeks’ gestation.   

 

2.48  In 2014, there were 132 abortions which involved selective terminations.  In 80 cases, two 



fetuses were reduced to one fetus.  In 35 cases, three fetuses were reduced to two fetuses 

and in 14 cases three fetuses were reduced to one fetus.  Over three quarters (83%) of the 

selective terminations were performed under ground E. 

 

2.49  The number of selective terminations has increased from around 50-80 in each of the last 



10 years to 125 in 2013 and to 132 in 2014.  The proportions of reductions, for example, 3 

fetuses reduced to 2 or 3 fetuses reduced to 1, over the years has stayed roughly the 

same, see Table D.

2.50  Abortions that are selective abortions are more likely to be for women who are married 

(75%), aged 30 and over (83%) and who are less likely to have had a previous abortions: 

only 6% of cases reported a previous abortion. 

 

Chlamydia screening  



 

2.51  The revised HSA4 forms introduced in 2002 allowed for the recording of whether 

chlamydia screening was offered.  The Royal College of Obstetricians and Gynaecologists 

recommend that all women undergoing an abortion should be screened for C. trachomatis 

and undergo a risk assessment for other STIs. Chlamydia is the most commonly 

diagnosed STI in England. Infection of varying degrees of severity may occur after medical 

or surgical abortion and is usually caused by pre-existing infection. Prophylactic antibiotic 

use and bacterial screening for lower genital tract infection reduces this risk.  Analysis of 

returned data for 2014 shows that 87% of women having abortions in 2014 were offered 

chlamydia screening, up from 69% in 2004.  (See Table 3a.x). The figure for women aged 

under 25 is slightly higher (91%) 

 

Place of residence within England and Wales  



 

2.52  The place of residence details provided on the HSA4 form are used to allocate each 

record to a Clinical Commissioning Group (CCG) for analysis.  For Wales, records are 

allocated to their equivalents, Local Health Boards.  Tables 10a, 10b, 11a and 11b show 

information for these areas. 

 

2.53  Similarly the place of residence details are used to allocate each record to a Local 



Authority (LA) and tables 10c, 10d, 11c and 11d show information by LA.

2.54  Rates vary by region with London showing the highest rate at 22 per 1,000 women. See 

Figure 8.

England and Wales, 2014 

 

 



 

 

Women resident outside England and Wales 



 

2.55  In 2014, there were 5,521 abortions to women resident outside England and Wales, 

compared with 5,469 in 2013.  Principally, these non-residents were from the Irish 

Republic (68%) and Northern Ireland (15%). See Tables 12a, c, d and Figure 9.   

 

2.56  The number of abortions to non-residents has fallen each year since 2003, when the figure 



was 9,078.  The 2014 total is slightly higher than 2013 which was the lowest in any year 

since 1969 (See Table 1 and Table 12a).

Abortions carried out in Great Britain   

 

2.57  There were 201,567 abortions carried out in Great Britain in 2014, of which 94% took 



place in England and Wales and 6% took place in Scotland (See Table 13).  Scotland 

perform the majority of abortions medically 80% compared to those performed in England 

and Wales where the proportions were surgical 50% and medical 50%.  The proportion of 

women undergoing abortions who had one or more previous abortions was higher for 

women having abortions in England and Wales (37%) than those having abortions in 

Scotland (32%).

Annex A: Data Quality and Methods 

 

 



  Validation  

 

i. 



The Department of Health use a thorough process for inspecting and recording the 

information received on the forms in order to monitor compliance with the legislation and 

the extent to which best practice guidance from the Department of Health is followed.  

Selected forms are scrutinised by a medical practitioner who may request further detail 

from the patient’s medical record via the terminating doctor.  Further details of the checks 

that are made on the data are available on the GOV.UK web site at: 

 

https://www.gov.uk/government/publications/abortion-notification-forms-for-england-and-



wales 

 



  Data collected 

 

 



Not all the information collected on form HSA4 is necessary for statistical purposes and 

some of the information that is used to monitor the Abortion Act is not stored 

electronically other than on scanned images of the forms.  The scanned images of the 

forms are part of the system for processing the forms and they are kept for three years.   

 

The following information is not stored: 



 

  Terminating and certifying doctors’ names 



  Terminating and certifying doctors’ addresses 

  Terminating doctor’s GMC number 



  Patient name  

  Patient reference including NHS number 



  Patient address 

  Detail about any medical conditions other than ICD10 Codes 



 

 



  Derived fields 

 

 



Some of the data used in the tables are derived variables.  More detail about these 

calculations is shown below: 

 



  Reported Date of Termination is from the date of the surgical treatment or, for 



medical abortions, the date of prostaglandin or other medical agent.  If a feticide 

is used, this date takes priority. 

  Age at Termination is taken from Reported Date of Termination (see above) 



minus date of birth.  Age at termination is collected in whole years.   

  Purchaser is derived from information given about how the abortion was funded 



(NHS or Privately) together with clinic type (NHS hospital, Independent Sector, 

Private hospital).  For example, a privately funded abortion within an Independent 



Abortion Statistics, England and Wales: 2014 

 

ii 



Sector organisation will be ‘privately funded’ and an NHS funded abortion within 

an Independent Sector clinic will be ‘NHS Funded: Independent Sector’. 

  Area of residence (CCG/LA/region) is derived from postcode of the woman’s 



residence. 

  Duration of stay is derived from date of discharge minus date of admission.   



 

 



  Forms returned after the publication cut-off date  

 

ii. 



The 2014 figures in this annual bulletin are based on a snapshot of the records taken 

about eight weeks prior to publication.  A small number of notifications have been, and 

will continue to be, received after this cut-off date.  Whilst these additional notifications 

are processed and the information retained in line with our retention policy, they are not 

included in future statistical releases.  So, for example, figures for 2013 published in the 

2013 bulletin have not been revised in this year’s bulletin.  This policy of not revising 

statistics is taken for three main reasons: 

 



  to prevent the disclosure of personal information arising from small differences in 

published tables; 

  to ensure consistency in published outputs over time; and 



  because the revisions would be small in scale and therefore of little value. 

 

iii. 


The scale of the effect is illustrated below for 2013.  A further 480 notifications were 

received after the cut-off, equating to a quarter of one per cent of the published total.  3 of 

these late notifications were for abortions over 23 weeks.  As the table below shows, the 

inclusion of this information would have resulted in no change in the percentage 

breakdowns by age group, gestation and grounds to one decimal place.

  Incomplete information and imputation 



 

iv. 


Incomplete and incorrectly completed forms are returned to practitioners for completion 

and clarification.  In a very small number of cases (about one-quarter of one percent), the 

information remains unavailable at the time of publication.  Date of birth was missing from 

5 records in 2014, gestation information from 37, postcodes from 32 and grounds from 

10. 

 

v. 



For the purposes of constructing statistics, values for missing items are imputed.  

Records with missing ages were assigned pro-rata to the 20-24 age group, as this is the 

modal age group, accounting for 29% of abortions.   Missing gestations were imputed as 

6, 7, 8, 9 or 10 weeks in equal distribution unless the method of abortion or diagnosis 

suggested otherwise.  Missing postcodes were imputed with a random postcode from 

within the main local authority of other residents attending the same hospital or clinic.  

Missing grounds were imputed as ground C 

 

 



 

  Population estimates used for rates of abortion 



 

vi. 


Abortion rates are calculated using the conventional age range for women in their child 

bearing years, 15 – 44. 

 

vii.  Abortion rates per 1,000 women for 2014 at a national level and at CCG level were 



calculated using the mid-2013 population estimates for England, Wales, England and 

Wales, Clinical Commissioning Groups and Locality Office, as published at 26

th

 June 


2014

1

.  Rates for earlier years were calculated using the latest population estimates 



available at the time the relevant annual reports were produced and have not been 

revised, either by using population estimates for the year in question or by using updated 

population estimates. 

 

 



  Deriving age standardised rates of abortion 

 

viii.  Age standardised rates allow comparison between populations which may contain 



different proportions of people of different ages. The European Standard Population 

(ESP) is a widely used artificial population structure for the calculation of directly age 

standardised rates. The replacement of the ESP first used in 1976 with an updated 

version published in 2013 resulted in an increase of all-cause mortality rates for England 

and Wales by 85% and all-site cancer incidence rates for England by some 48%. Figures 

using the 1976 and 2013 ESPs are therefore not comparable. Information about this 

change in methods can be found on the ONS website at:

ix. 

The effect of implementing the 2013 ESP for abortion age standardised rates is small. 

The vast majority of abortions occur within the age range 15-44. The 1976 ESP assumed 

equal populations at each single age between 15-44 (see Annex table 1 below). The 

2013 ESP has made only a small change to the populations within age range 15-44 such 

that although not equal, it remains fairly uniform. Thus, the 2013 ESP brings the abortion 

age standardised rates down by about 4% in recent years and 2% in earlier years. The 

time series using 2013 ESP age standardised rates back dated to 1968 is presented in 

table 1 of the detailed tables.

The formulae used to calculate the age-standardised abortion rates are given below.

  Confidence intervals 

 

xi. 



The figures recorded in this report are the outcome of a stochastic process – that is, they 

are influenced by chance or random processes such as fertilisation.  Each recorded 

figure is only one of a range of results that could have occurred under the same 

circumstances if those random processes had led to different outcomes.  It is often the 

underlying circumstances or process that is of interest and the actual value observed 

gives only an imprecise estimate of this ‘underlying risk’.  For example, users are often 

interested in understanding whether there has been a change in rates of abortion, 

perhaps reflecting a change in the prevalence of risky sexual behaviour, a change in 

attitudes towards the options available in pregnancy or a change in access to services.  

To assess this, it is necessary to determine if the observed change is one that is unlikely 

to be the result of random fluctuation and therefore offers evidence that a real change 

has occurred.  

 

xii.  A confidence interval can be calculated around each observed value, which gives a range 



in which the expected or average value resulting from the underlying process is likely to 

fall.  The 95 per cent confidence intervals have been calculated for some of the observed 

values in tables 10a, 10b, 10c and 11. These are known as such, because if it were 


Abortion Statistics, England and Wales: 2014 

 

vi 



possible to repeat the underlying process under the same conditions a large number of 

times (that is, ‘rerun’ the year over and over again), 95 per cent of the confidence 

intervals calculated in this way would contain the average value from those runs.  When 

assessing the observed results for the year, it is usual to assume that there is only a 5 per 

cent chance that the expected or average value falls outside the 95 per cent confidence 

interval. 

 

xiii.  The confidence interval may be used to compare an estimate against a target or 



benchmark value.  If the target or benchmark value is outside the confidence interval it 

can be inferred that the difference between the estimate and the target is statistically 

significant at the 95 per cent confidence level. 

 

xiv.  Confidence intervals are also often used to compare two observed values (for example, 



abortion rates within two regions.)  Sometimes in such cases statistical testing is 

undertaken by seeing if the two confidence intervals overlap.  This is quick and easy to 

do, but not necessarily conclusive: whilst it is safe to assume that non-overlapping 

confidence intervals indicate a statistically significant difference, it is not always the case 

that overlapping confidence intervals do not. 

 

xv.  The method for estimating a confidence interval varies depending on whether it is for a 



percentage, count, crude rate or standardised rate.  The methods used are those detailed 

in the Association of Public Health Observatories’ Technical Briefing 3: Commonly used 

public health statistics and their confidence intervals. 

 

xvi.  For example, the 95 per cent confidence interval associated with: 



 

  The figure of 184,571 for the total number of abortions of residents in England and 



Wales is 183,730 – 185,415 (Table 10a);

  

 



  The age standardised rate of 15.92 abortions per 1000 resident women aged 15-44 in 

England and Wales is 15.9 to 16.0 (Table 10b);  

  The figure of 84.5 per cent for the percentage of NHS funded abortions in NHS 



Eastern Cheshire CCG undertaken within 10 weeks gestation is 80.5 per cent to 87.7 

per cent (Table 11). 

 



  Disclosure Control 



 

xvii. 


The Data Protection Act 1998 places a statutory obligation on the Department of Health 

to ensure that the statistics we release on abortion do not relate to a living individual who 

can be identified from those data alone or in conjunction with other available information, 

unless the conditions laid out in the Act are met.  In recent years, the Department has 

attempted to meet this obligation by following the disclosure guidance for abortion 

statistics developed by the Office for National Statistics in July 2005.  A judgment was 

handed down in 2011 by the High Court in a case relating to the release of information on 

principal medical condition for abortions performed under Ground E, showed that the 

disclosure controls set out in the guidance were overly cautious in some circumstances.  

The format of the tables in the annual report have therefore been revised, with a more 

limited degree of suppression applied, where still necessary to avoid the disclosure of 

personal data.

  Geographical coding and naming 

 

xix.  On 1st January 2011, the Government Statistical Service introduced a new coding and 



naming policy for statistical geographies.  Nine-digit codes have been developed to 

ensure consistency when comparing geographical areas as the geographical area 

covered by an NHS organisation is susceptible to change.  These unique markers have 

been added to the relevant tables within this publication.   

 

xx.  On the 1



st

 April 2013 Clinical Commissioning Groups assumed commissioning of 

termination of pregnancy services under the health system reforms.  Further information 

on the Coding and Naming for Statistical Geographies is available at:
