Determinants of malaria prophylaxis among German travelers to Kenya, Senegal, and Thailand.

BACKGROUND: Malaria chemoprophylaxis is a mainstay of malaria prevention in travelers. Adequate pretravel advice forms the basis for efficient malaria prophylaxis. This study assessed the determinants for seeking pretravel advice and evaluated the quality of advice from each source and its influence on the patterns and outcome of malaria prophylaxis intake. METHODS: In March and April 2004, a self-administered questionnaire was distributed by cabin crews to passengers flying back to Germany from three popular tourist destinations: Kenya, Senegal, and Thailand. To evaluate the quality of advice and actual intake, figures were assessed against the official recommendations of the German Society of Travel Medicine and International Health (DTG). RESULTS: A total of 1,001 passengers were included in the study (Kenya, 492; Senegal, 131; and Thailand, 378), of which 81% had sought any kind of pretravel health advice. Travelers' age and time of pretravel consultation were associated with the source of information consulted. Seventy-five percent of travelers from Senegal and Kenya received DTG compliant advice compared to only 17% of travelers from areas with low malaria risk in Thailand. Travelers returning from Kenya and Senegal had used correct chemoprophylaxis in only 65 and 47% of trips, respectively. In multivariate analysis, the factors determining correct intake among Senegal and Kenya travelers were receiving pretravel advice (from nonmedical professionals: OR 4.4, 95% CI 1.9-10.0 and from medical professionals: OR 15.4, 95% CI 7.3-32.4), a correct risk perception (OR 2.9, 95% CI 1.9-4.5), 2 to 3 weeks of travel abroad (vs a duration >3 wk: OR 2.2, 95% CI 1.3-3.8), and travel to Kenya (OR 1.9, 95% CI 1.1-3.1). CONCLUSIONS: Malaria prevention among a large proportion of German travelers to tropical destinations is inadequate. Public health efforts should be made to raise awareness among travelers, travel agencies, and medical institutions in Germany.

Notifiable disease surveillance and practicing physicians.

Primary care physicians in Germany are essential participants in infectious disease surveillance through mandatory reporting. Feedback on such surveillance should reflect the needs and attitudes of these physicians. These issues were investigated in a questionnaire survey among 8,550 randomly sampled physicians in Germany in 2001. Of the 1,320 respondents, 59.3% claimed not to have received any feedback on infectious disease surveillance, and 3.7% perceived feedback as not important. Logistic regression analysis showed that physicians in the former East Germany were 2.2 times more likely to have received feedback than those in the former West Germany. Physicians preferred to receive occasional reports (e.g., in case of outbreaks, 31.6%) as opposed to actively having to search for constantly updated information on the Internet (7.8%). The preferred formats were fax (31.7%), mail (30.9%), and the official organ of the German Medical Association (Deutsches Arzteblatt) (30.5%). Feedback of surveillance data to physicians should be delivered through occasional nonelectronic reports on current issues of local public health importance.

Nationwide survey of the role of travel medicine in primary care in Germany.

BACKGROUND: With more persons traveling to (sub)tropical destinations, travel medicine is an increasing challenge for the health care system in many countries. This study investigated the role and scope of travel medicine provided by general practitioners (GPs) in primary health care, assessed the determinants of specific prophylactic recommendations, and identified the needs of GPs regarding training and cooperation in travel medicine. METHODS: A national survey was conducted among randomly selected GPs in Germany. Information on the type and extent of activities in travel medicine, the number and characteristics of patients, the use of specific information systems, and training and cooperation, was obtained with a standardized postal questionnaire. Representativeness was assessed by a computer-assisted telephone survey among nonrespondents. Univariate and multivariate statistical analysis was performed. RESULTS: Of all GPs (n=1,320), 95% provided medical pretravel advice or post-travel counseling (13.2 patients/month). The most common topics in pretravel consultation were immunizations (95%), malaria chemoprophylaxis (94%), advice on exposure prophylaxis (41%), and advice on protection from sexually transmitted infections (STIs) (43%). GPs frequently advised certain patient groups (e.g., cardiovascular patients 68%, pregnant women 20%). Travelers' diarrhea was the most common topic in post-travel consultation (89%), followed by fever (38%). Of the GPs, 25% cooperated regularly with institutions with special expertise in travel medicine or tropical diseases. Sixty-four percent had received some training in travel medicine, and 86% stated a need for additional training. In the multivariate analysis, independent determinants for advice on exposure prophylaxis and STI risks included special training in travel medicine, use of country-specific information sources, and location of the practice in the former West Germany and urban areas. CONCLUSIONS: Travel medicine is of importance in primary health care in Germany. There is a need for improved counseling on exposure and STI prophylaxis. GPs' training in travel medicine and cooperation with institutions such as institutes, clinics and laboratories for tropical medicine should be improved.
