Background: In 1993 more than 1 million Swiss residents traveled to a tropi
cal or subtropical country. Although most pretravel advice is given by gene
ral practitioners, a number of travelers also seek advice from pharmacists.
Little is known about the quantity and quality of travel advice given or t
he sources of information used by this group.
Methods: One-hundred and twenty randomly selected pharmacists from three Sw
iss cantons were first interviewed in a cross-sectional study on the teleph
one. All study participants subsequently received a pretested questionnaire
, in which most of the questions asked on the phone were repeated, with add
itional questions regarding the sources of information used for travel advi
ce and the cooperation of general practitioners. Included in both parts of
the study were two scenarios of fictive travelers seeking health advice for
destinations frequently visited by Swiss tourists (Thailand and Kenya).
Results: Of 136 pharmacists approached, all who said they sometimes gave tr
avel advice, agreed to participate (88%). Fifty-six percent of them give tr
avel advice regularly (mean 2-3 times per month). General knowledge on the
main health hazards was good, but for treatment of travelers' diarrhea, onl
y 59% spontaneously mentioned the need for increased fluid intake, whereas
100% recommended antidiarrheal drugs. Protection from the sun was mentioned
only by 10% of the respondents, and only 8% said that the traveler should
seek advice from a medical doctor. Over 95% could name the three most impor
tant measures against mosquito bites, although up to 20% still recommend Vi
tamin B1 as well. On the telephone, only 19% (for Thailand) and 31% (for Ke
nya) gave accurate advice on malaria protection, and 13% (for Thailand) and
3% (for Kenya) could make correct recommendations about vaccination. Howev
er, more than 50% said that in practice they would consult documentation be
fore giving any advice, with the Bulletin of the Federal Office of Health (
BFOH) being the most commonly used source of information. In the questionna
ire interview, where documentation was used, the accuracy of advice increas
ed, especially for malaria protection (74% correct for Thailand and 93% for
Kenya).
Conclusions: The overall knowledge of Swiss pharmacists on travel medicine
issues is satisfactory. Specific questions need further attention, such as
treatment of travelers' diarrhea, sun protection and advice on malaria prop
hylaxis and vaccinations. For the latter two, clients should also consult a
medical doctor. Collaboration between doctors and pharmacists, and the con
sistency of the advice given, are important in improving compliance. Reliab
le information sources are available in pharmacies and are used.
