Interviews were conducted with 104 patients who had participated in medical
research involving pharmaceutical drugs. All patients were asked about the
amount of information they had been given prior to being invited to partic
ipate, and about their understanding of, and satisfaction with, that inform
ation. Patients were also invited to comment on their reasons for having ag
reed to take part in medical research. Each had participated in one of 14 d
ifferent drug studies. One of these studies involved a drug that was being
used for the first time during labour When analysing these data, it became
apparent to the author that responses from some of those involved in the la
bour drug study were different from those of patients who had participated
in the other studies. This paper compares the views of the 26 patients in t
he labour study with those of the 78 other patients. The women in the labou
r trial were generally less satisfied than patients in the comparative samp
le with the information which they had been given, and reported lower level
s of understanding of that information. They had asked fewer questions abou
t their study and reported lower levels of satisfaction with the answers th
ey had received to those questions. This raises concerns as to whether the
consent to participation given by women in the labour trial was in all case
s fully informed. This in turn suggests the possibility of a gender bias in
fulfilling ethical obligations in medical research.
