Effect of carbapenem resistance on outcomes of bloodstream infection caused by Enterobacteriaceae in low-income and middle-income countries (PANORAMA): a multinational prospective cohort study.

BACKGROUND: Low-income and middle-income countries (LMICs) are under-represented in reports on the burden of antimicrobial resistance. We aimed to quantify the clinical effect of carbapenem resistance on mortality and length of hospital stay among inpatients in LMICs with a bloodstream infection due to Enterobacteriaceae. METHODS: The PANORAMA study was a multinational prospective cohort study at tertiary hospitals in Bangladesh, Colombia, Egypt, Ghana, India, Lebanon, Nepal, Nigeria, Pakistan, and Vietnam, recruiting consecutively diagnosed patients with carbapenem-susceptible Enterobacteriaceae (CSE) and carbapenem-resistant Entero-bacteriaceae (CRE) bloodstream infections. We excluded patients who had previously been enrolled in the study and those not treated with curative intent at the time of bloodstream infection onset. There were no age restrictions. Central laboratories in India and the UK did confirmatory testing and molecular characterisation, including strain typing. We applied proportional subdistribution hazard models with inverse probability weighting to estimate the effect of carbapenem resistance on probability of discharge alive and in-hospital death, and multistate modelling for excess length of stay in hospital. All patients were included in the analysis. FINDINGS: Between Aug 1, 2014, and June 30, 2015, we recruited 297 patients from 16 sites in ten countries: 174 with CSE bloodstream infection and 123 with CRE bloodstream infection. Median age was 46 years (IQR 15-61). Crude mortality was 20% (35 of 174 patients) for patients with CSE bloodstream infection and 35% (43 of 123 patients) for patients with CRE bloodstream infection. Carbapenem resistance was associated with an increased length of hospital stay (3·7 days, 95% CI 0·3-6·9), increased probability of in-hospital mortality (adjusted subdistribution hazard ratio 1·75, 95% CI 1·04-2·94), and decreased probability of discharge alive (0·61, 0·45-0·83). Multilocus sequence typing showed various clades, with marginal overlap between strains in the CRE and CSE clades. INTERPRETATION: Carbapenem resistance is associated with increased length of hospital stay and mortality in patients with bloodstream infections in LMICs. These data will inform global estimates of the burden of antimicrobial resistance and reinforce the need for better strategies to prevent, diagnose, and treat CRE infections in LMICs.

[Implementation of the strategy "Clean Care is Safer Care" in a third level hospital in Medellín, Colombia]. / Implementación de la estrategia "Atención Limpia es Atención Segura" en un hospital de tercer nivel en Medellín, Colombia.

INTRODUCTION: Hand hygiene is the most cost-effective and simple measure of preventing healthcare associated infections (HAI). The approach to improve low compliance must be through multimodal interventions such as the "Clean Care is Safer Care" strategy (WHO). AIM: To estimate the efficacy of a multimodal strategy in improving hand hygiene in five wards of a tertiary care hospital in Medellín, Colombia (2008-2010). METHODS: Quasi-experimental before-after study. RESULTS: Hand hygiene compliance significantly increased after the intervention (82 to 89%, p = 0.007). The knowledge score increased from a median of 26 (IQR=22-28) to 30 (IQR=26-32, p = 0.001). Alcohol-based hand rub consumption increased significantly from 10.5 liters to 58.1 liters per 1000 patient-days [incidence ratio (IR) = 2.39, 95% CI = 1.99; 2.88]. Monthly HAI rates showed no significant variations during the same period [IR = 0.90, 95% CI = 0.71; 1.13]. DISCUSSION: This and other recent studies demonstrate that implementing a multimodal strategy for hand hygiene significantly increases compliance with this measure, irrespective of type of health worker or hospital department. CONCLUSIONS: Implementing a multimodal strategy we achieved significant increases in hand hygiene compliance but mild or no significant variations in monthly HAI rates.

Introducción: La higiene de manos es una medida costo-efectiva para prevenir las infecciones asociadas a la atención de salud (IAAS). Para mejorar el cumplimiento se recomienda implementar estrategias multimodales como "atención limpia es atención segura" de la OMS. Objetivo: Estimar el efecto de la estrategia multimodal en cinco unidades de un hospital de tercer nivel en Medellín, Colombia (2008-2010). Métodos: Estudio cuasi-experimental antes y después. Resultados: El cumplimiento general con la higiene de manos aumentó de forma significativa en el período posterior a la implementación (82 a 89%, p = 0,007). El puntaje de conocimientos aumentó entre los dos períodos de tiempo (Mediana = 26, RIC = 22-28 vs Mediana = 30, RIC = 26-32; p = 0,001). El consumo de alcohol aumentó de 10,5 litros a 58,1 litros por 1.000 pacientes/día [razón de incidencias (RI) = 2,39; 95% CI = 1,99; 2,88]. Las tasas mensuales de IAAS no mostraron variaciones [RI = 0,90; 95% CI = 0,71; 1,13]. Discusión: Este estudio demuestra que la implementación de una estrategia multimodal para la higiene de manos aumenta significativamente el cumplimiento con esta medida, independientemente del tipo de trabajador y el servicio hospitalario. Conclusión: Con la estrategia multimodal se aumentó significativamente el cumplimiento con la higiene de manos.

Paracoccidiodomicosis: coexistencia de lesiones extrapulmonares y patología pulmonar silente. Descripción de 64 pacientes

Se revisaron las historias clínicas y los resutados de los exámenes paramédicos correspondientes a 64 pacientes con paracoccidioidomicosis, que consultaron por lesiones extrapulmonares. A pesar de ello, en el momento de estabreser el diagnóstico, 57 (89 por ciento) presentaban patología pumonar demostrable en la radiografía de tórax y 36 (56.2 por ciento) tenían cultivo de esputos positivos para P. brasiliensis. puestos que estos pacientes no consutaron por síntomas que sugirieron afección respiratoria, los hallazgos anteriores revelan la frecuenciadel compromiso pulmonar silente en esta micosis. Iigualmente, estos datos señalan al pulmón como el órgano de afección primaria.
