Beperkte deelname aan tuberculinescreening onder reizigers naar landen met hoge tuberculose-incidentie; reden om voor sommigen BCG-vaccinatie te overwegen

To determine the compliance amongst Dutch travellers to high tuberculosis-incidence countries with a screening procedure involving a tuberculin skin test before and after the trip.

Design

Prospective study.

Method

Nine hundred and eighty-eight tuberculin-negative Dutch people who travelled to high tuberculosis-incidence countries for 3 to 12 months were studied for their compliance with an advised screening procedure of repeat tuberculin skin testing 2 to 4 months after return. At 2 of the 4 participating health services, data were also collected on extra calls made and the pertinent time investments.

Results

Five hundred and ninety-nine travellers (61) were compliant with the screening procedure. Of those for whom the data was available (n = 417), 33 (98/300) of the compliant travellers required extra calls. These took an average of 30 min per extra traveller tested as a result. Compliance varied according to health service and was better amongst travellers to Africa. In addition, non-compliance was independently associated with male sex, work being the main travel purpose, and an undecided duration of travel on departure.

Conclusions

Compliance of Dutch travellers with tuberculin skin-test screening is limited, particularly if no extra calls are issued. Bacillus Calmette-Guérin vaccination appears to be preferable for travellers with undecided travel duration and persons travelling for work on a frequent basis.
