Third, if two CYC202 price conditionally dependent findings are entered, only the one with the highest positive likelihood ratio is accounted for. Finally, at every step, the sum of all probabilities is reset at 100%. At any time during the consultation, the user can also ask the help of the tutor module that lists the relevant findings to explore, or suggests step-by-step further testing, with reassessment

of the case each time a new finding is entered (“wizard” button). The tutor will not end the case before the probability of a diagnosis is considered high enough by the system (over the treatment threshold), before all relevant excluders for this disease have PKC inhibitor been exhausted, and before

competing dangerous and treatable diagnoses are sufficiently excluded. Following this study and coinvestigator’s suggestions, KABISA TRAVEL has been upgraded recently, but with no major modifications. The software is now freely accessible at www.kabisa.be: KABISA V; setting “Travel clinic”; module “Expert. A first single-center retrospective study has evaluated the KABISA TRAVEL in 54 febrile travelers presenting at a Belgian emergency ward and demonstrated that 93% of the cases were correctly diagnosed.12 The present study intended to assess prospectively the diagnostic accuracy of the KABISA TRAVEL in different European settings dealing with travel-related pathology, and to compare it to travel physicians’ performances. Secondary objectives were to evaluate the clinical utility of the KABISA TRAVEL software and (-)-p-Bromotetramisole Oxalate the specific contribution of the tutor. From December 2007 to April 2009, travelers with fever after a stay in the tropics were included prospectively in a multicenter trial conducted in 10 referral travel clinics located in the Netherlands, Italy, Spain, and Belgium (nine tertiary referral hospitals with

travel clinics and one outpatient referral travel clinic). Anonymous data from all collaborating centers were centralized and analyzed at the Institute of Tropical Medicine, Antwerp, Belgium. We prospectively enrolled patients of any age presenting at one of the study centers with ongoing fever occurring within 3 months after a stay in the tropics. Ongoing fever was defined by an axillary temperature of 38°C or higher, documented by the patient or a physician whenever in the past 3 days before the first consultation. Tropics and subtropics corresponded to all countries at least partly situated between the 35°-northern and 35°-southern latitude, except the United States, European countries, Japan, and Australia. The study patients were clinically managed by each coinvestigator (all of them being physicians with expertise in travel medicine) according to the usual standard of care in each site/country.
