The prescribing behaviour of family doctors in Hong Kong towards upper resp
iratory tract infections (URTIs) and the factors that might affect such beh
aviour were studied. All 1016 members of the Hong Kong College of Family Ph
ysicians were sent a postal questionnaire. A total of 730 family doctors co
mpleted the questionnaire, with an overall response rate of 71.8%. Doctors
who were older, more senior, or in private practice were more likely to thi
nk antibiotics were useful for URTIs and to prescribe them. These doctors w
ere also more likely to think their patients would expect antibiotics from
them. Postgraduate vocational training in general practice/family medicine
helped make family doctors think fewer patients would expect antibiotics fr
om them but did not affect their perception of the usefulness of antibiotic
s for URTIs. Our results showed that doctors with certain characteristics w
ere more likely to prescribe antibiotics for URTIs and these doctors may be
targeted for continued medical education.
