Objective: To evaluate the impact of randomised clinical trials (RCT) on de
cision-making and therapeutic policies among general and gastrointestinal s
urgeons in France.
Design: Telephone questionnaire.
Setting Multicentre study, France.
Subjects: A random sample of 152 surgeons, mean (SD) age 50 (8) years.
Interventions and Main outcome measure: Surgeons were asked 12 questions ab
out their knowledge of RCT and how trials were conducted; influence of RCT
on their treatment policies; means of obtaining information about treatment
s; how they evaluated their own results; whether they were willing to take
part in RCT; and personal details including age, speciality, and type of pr
actice. Surgeons were stratified according to age and type of practice.
Results: 148 questionnaires were suitable for analysis. 83 surgeons (56%) w
ere under 50 years old, 38 (26%) were exclusively gastrointestinal surgeons
, 82 (56%) worked in private practice, and 36 (24%) worked in teaching and
university hospitals. The rest undertook mixed duties. When asked to say wh
ere they obtained their knowledge about antibiotics, 91 (61%) referred to R
CT; these were mainly hospital-based, gastrointestinal, and younger surgeon
s. Asked to name a RCT-based policy, 81 (55%) gave medical rather than oper
ative examples. 80 (54%) had already participated in a RCT; 79 (53%) said t
hat they were willing to participate in a RCT that included random allocati
on of patients (there were no statistically significant differences in answ
ers according to speciality or type of practice, although younger surgeons
answered "yes" to both questions). Specialised journals were the main sourc
e of information for 115 (78%), and surgeons read a mean of 40 issues/year.
142 (96%) read journals in French and 66 (45%) in English, but this number
fell to 10 (15%) of the 65 surgeons aged 50 or more. Personal experience w
as considered a more important source of therapeutic knowledge by older and
specialist surgeons. 109 surgeons (74%) recalled patients during the first
month postoperatively to evaluate their results.
Conclusions: French surgeons, particularly those aged 50 or over, are not w
ell informed about the nature, conduct, and value of RCT. Most of their inf
ormation is acquired through reading and attending scientific meetings and
congresses. Surgeons tended to attach more importance to the fame of the au
thor than to the conduct of the study. The overall impact of RCT was weak a
mong the surgeons questioned.
