Background. About one third of all pregnancies are unplanned and 20% o
f all pregnancies end in abortion. More than 170 000 legal abortions a
re performed in the United Kingdom annually Nearly all general practit
ioners provide contraceptive advice; the most commonly used form of re
versible contraception is the oral contraceptive pill. Aim. The aim of
this study was to determine factors associated with women's knowledge
of taking the contraceptive pill correctly and of emergency contracep
tion, and to investigate if their knowledge could be improved in gener
al practice by providing women with Family Planning Association inform
ation leaflets. Method. An uncontrolled intervention study was perform
ed in one rural and one urban English general practice, using a self-c
ompletion questionnaire that was initially administered to women atten
ding their general practitioner for oral contraception over six months
from 1 October 1992. The questionnaire asked for: sociodemographic in
formation; knowledge of how late women can be taking an oral contracep
tive pill and still be protected against unplanned pregnancy; for how
many days after being late with a pill they need to use other precauti
ons; sources and methods of emergency contraception; and for how long
the methods are effective after the primary contraceptive failure. Aft
er completing the questionnaire women were given two leaflets: one abo
ut how to take their prescribed contraceptive pill correctly and one a
bout emergency contraception. Three to 12 months later the same questi
onnaire was administered in the same manner. Results. Of 449 women com
pleting the first questionnaire, 233 (52%) completed the second questi
onnaire. Initially 71% of 406 women taking an oestrogen/progestogen co
mbined pill knew about the '12-hour rule' and 17% knew about the 'seve
n-day rule'; giving women information about the pill they were taking
increased the extent of knowledge about these rules among 212 responde
nts to 82% (P < 0.01) and to 25% (P < 0.05), respectively. The proport
ion of respondents who, knew that they could obtain emergency contrace
ption from their own general practitioner, from any general practition
er and from family planning clinics all increased after they had recei
ved the leaflets (from 84% to 92%, from 34% to 47% and from 82% to 90%
, respectively, all P < 0.01). There were significant improvements in
the proportion of women knowing the duration of effectiveness of emerg
ency contraception. However, after receiving the leaflet on emergency
contraception the majority of women still did not know for how long af
ter unprotected intercourse the high-dose combined pill and the intrau
terine contraceptive device were effective (80% and 93% of 233 women,
respectively). Improvements in knowledge depended upon women's social
class, previous use of emergency contraception and with which practice
they were registered. Conclusion. Providing women with leaflets about
taking the contraceptive pill correctly and about emergency contracep
tion appears to improve significantly their extent of such knowledge.
If such practice was adopted elsewhere this increased knowledge might
reduce the number of unplanned pregnancies in the UK. The effect of ge
neral practitioners personally providing such leaflets, with or withou
t verbal instruction, warrants further study.
