ABSTRACT
Identifying the risk factors for carbapenem-resistant Enterobacterales (CRE) bacteremia in cancer and hematopoietic stem cell transplantation (HSCT) patients would allow earlier initiation of an appropriate empirical antibiotic treatment. This is a prospective multicenter observational study in patients from 12 centers in Argentina, who presented with cancer or hematopoietic stem-cell transplant and developed Enterobacterales bacteremia. A multiple logistic regression model identified risk factors for CRE bacteremia, and a score was developed according to the regression coefficient. This was validated by the bootstrap resampling technique. Four hundred and forty-three patients with Enterobacterales bacteremia were included: 59 with CRE and 384 with carbapenem-susceptible Enterobacterales (CSE). The risk factors that were identified and the points assigned to each of them were: ≥10 days of hospitalization until bacteremia: OR 4.03, 95% CI 1.88-8.66 (2 points); previous antibiotics > 7 days: OR 4.65, 95% CI 2.29-9.46 (2 points); current colonization with KPC-carbapenemase-producing Enterobacterales: 33.08, 95% CI 11.74-93.25 (5 points). With a cut-off of 7 points, a sensitivity of 35.59%, specificity of 98.43%, PPV of 77.7%, and NPV of 90.9% were obtained. The overall performance of the score was satisfactory (AUROC of 0.85, 95% CI 0.80-0.91). Finally, the post-test probability of CRE occurrence in patients with none of the risk factors was 1.9%, which would virtually rule out the presence of CRE bacteremia.
ABSTRACT
INTRODUCTION: Although Buenos Aires is the biggest province in Argentina, there was no program for Travel Medicine in any public hospital until 2008, when the Travel Medicine Center (CEMEVI) was established in our hospital. OBJECTIVE: To analyze the first 24 months of experience in the CEMEVI. RESULTS: A total of 278 travelers were assisted. Most of them consulted before traveling (pre-travel visits). The most common destinations were countries in South America and urban as well as rural areas. Travelling to malaria and yellow fever endemic countries represented 35% and 16% of the total of destinations, respectively. Only 4% were post-travel interviews. CONCLUSION: It is feasible and fruitful to implement a Travel Medicine Center in the public health system.

Introducción: La Provincia de Buenos Aires, a pesar de ser la mayor de nuestro país, no contaba con ningún sitio de asesoramiento al viajero instalado en un hospital público, hasta que en el año 2008 se crea el Centro de Medicina del Viajero (CEMEVI) en nuestro hospital. Objetivo: analizar de manera retrospectiva los primeros 24 meses de experiencia en el CEMEVI. Resultados: Recibimos un total de 278 consultas, la mayoría durante el pre-viaje, a países de América del Sur, a sitios urbanos- rurales, de los cuales 35 y 16% de los viajeros visitaron zonas de riesgo para malaria y fiebre amarilla, respectivamente. Sólo 4% de las consultas fueron en el post-viaje. Conclusión: Es posible y fructífero implementar un Centro de Medicina del Viajero en el sector público de salud.
