RESUMEN
IMPORTANCE: Infection is frequent among patients in the intensive care unit (ICU). Contemporary information about the types of infections, causative pathogens, and outcomes can aid the development of policies for prevention, diagnosis, treatment, and resource allocation and may assist in the design of interventional studies. OBJECTIVE: To provide information about the prevalence and outcomes of infection and the available resources in ICUs worldwide. DESIGN, SETTING, AND PARTICIPANTS: Observational 24-hour point prevalence study with longitudinal follow-up at 1150 centers in 88 countries. All adult patients (aged ≥18 years) treated at a participating ICU during a 24-hour period commencing at 08:00 on September 13, 2017, were included. The final follow-up date was November 13, 2017. EXPOSURES: Infection diagnosis and receipt of antibiotics. MAIN OUTCOMES AND MEASURES: Prevalence of infection and antibiotic exposure (cross-sectional design) and all-cause in-hospital mortality (longitudinal design). RESULTS: Among 15â¯202 included patients (mean age, 61.1 years [SD, 17.3 years]; 9181 were men [60.4%]), infection data were available for 15â¯165 (99.8%); 8135 (54%) had suspected or proven infection, including 1760 (22%) with ICU-acquired infection. A total of 10â¯640 patients (70%) received at least 1 antibiotic. The proportion of patients with suspected or proven infection ranged from 43% (141/328) in Australasia to 60% (1892/3150) in Asia and the Middle East. Among the 8135 patients with suspected or proven infection, 5259 (65%) had at least 1 positive microbiological culture; gram-negative microorganisms were identified in 67% of these patients (n = 3540), gram-positive microorganisms in 37% (n = 1946), and fungal microorganisms in 16% (n = 864). The in-hospital mortality rate was 30% (2404/7936) in patients with suspected or proven infection. In a multilevel analysis, ICU-acquired infection was independently associated with higher risk of mortality compared with community-acquired infection (odds ratio [OR], 1.32 [95% CI, 1.10-1.60]; P = .003). Among antibiotic-resistant microorganisms, infection with vancomycin-resistant Enterococcus (OR, 2.41 [95% CI, 1.43-4.06]; P = .001), Klebsiella resistant to ß-lactam antibiotics, including third-generation cephalosporins and carbapenems (OR, 1.29 [95% CI, 1.02-1.63]; P = .03), or carbapenem-resistant Acinetobacter species (OR, 1.40 [95% CI, 1.08-1.81]; P = .01) was independently associated with a higher risk of death vs infection with another microorganism. CONCLUSIONS AND RELEVANCE: In a worldwide sample of patients admitted to ICUs in September 2017, the prevalence of suspected or proven infection was high, with a substantial risk of in-hospital mortality.

INTRODUCTION: Sepsis is one of the main reasons for consultation at emergency departments. OBJECTIVE: To identify the prevalence of sepsis in emergency departments of Mexico. METHOD: Cross-sectional study with a 30-day follow-up of patients diagnosed with sepsis or septic shock; demographic variables, management and outcomes were analyzed. RESULTS: In 68 emergency departments analyzed, 2379 patients were attended to, out of whom 307 had sepsis. The prevalence of sepsis was 12.9 %, and overall mortality was 16.93 %, which in the cases of sepsis was 9.39 %, and in those of septic shock, 65.85 %; no significant differences were identified in demographic variables or type of hospital. A significantly higher fluid balance was observed within the first three hours in those patients who died, as well as a lack of adherence to international resuscitation recommendations. CONCLUSIONS: A high prevalence of sepsis was found in Mexican emergency departments. Mortality of patients with septic shock was similar and even higher than that internationally reported. INTRODUCCIÓN: La sepsis es una de las principales causas de consulta en los servicios de urgencias médicas. OBJETIVO: Identificar la prevalencia de la sepsis en servicios de urgencias médicas de México. MÉTODO: Estudio transversal con seguimiento a 30 días de los pacientes con diagnóstico de sepsis o choque séptico; se analizaron las variables demográficas, el manejo y los desenlaces. RESULTADOS: En 68 servicios de urgencias médicas analizados se atendió a 2379 pacientes, de los cuales 307 presentaron sepsis. La prevalencia de la sepsis fue de 12.9 %, con mortalidad global de 16.93 %, que en los casos de sepsis fue de 9.39 % y en los de choque séptico, de 65.85 %; no se identificaron diferencias significativas en las variables demográficas o tipo de hospital. Se observó balance hídrico alto en las primeras tres horas y falta de apego a las recomendaciones internacionales de reanimación superior en los pacientes que fallecieron. CONCLUSIONES: Se encontró alta prevalencia de la sepsis en los servicios de urgencias médicas mexicanos. La mortalidad de los pacientes con choque séptico fue similar e, incluso, mayor a la reportada internacionalmente.

BACKGROUND: Measurement of intra-abdominal pressure (IAP) is realized with the Kron's method. However, this technique has drawbacks like an infusion of water into the bladder of the patient. OBJECTIVE: The prove a new novel disposable sensor in the way to measure the IAP (DSIAP) this one addresses some limitations of the Kron method. MATERIALS AND METHODS: The DSIAP was tested in vitro and clinical settings. The proposed technique was compared with Kron's method through Pearson correlation and Bland-Altman analysis. For in vitro tests, 159 measurements were taken performed by simulating the IAP in the bladder. For the clinical test, 20 pairs of measurements were made in patients with routine IAP monitoring in the intensive care unit. RESULTS: In vitro measurements showed a strong correlation between the DSIAP and the reference (r = 0.99, p-value < 2.2 × 10-16). The bias and 95% confidence intervals were 0.135 and -0.821-1.091 cmH2O, respectively. Measurements in patients with DSIAP versus Kron's method shown a very good correlation (r = 0.973, p-value < 5.46 × 10-13), while the bias and confidence intervals were 0.018 and -3.461-3.496 mmHg, respectively. CONCLUSIONS: The results suggest that the proposed DSIAP showed a profile similar to pressure transducers already in clinical use while overcoming some limitations of the former.
ANTECEDENTES: La medición de la presión intraabdominal (PIA) generalmente se realiza con el método de Kron, a pesar de presentar inconvenientes como la infusión de agua en la vejiga del paciente. OBJETIVO: Introducir un nuevo sensor desechable para medir la PIA (SDPIA) que aborda algunas limitaciones del método de Kron. MÉTODO: Se probó el SDPIA en pruebas in vitro y clínicas. La técnica se contrastó con el método de Kron empleando la correlación de Pearson y el análisis de Bland-Altman. Para las pruebas in vitro se realizaron 159 mediciones simulando la PIA en la vejiga. Para las pruebas clínicas se realizaron 20 mediciones en pacientes con monitorización rutinaria de la PIA en la unidad de cuidados intensivos. RESULTADOS: En las mediciones in vitro se encontró una alta correlación (r = 0.99; p < 2.2 × 10−16). El sesgo para la diferencia entre los dos métodos de medición fue de 0.135 cmH2O, con un intervalo de confianza del 95% de −0.821 a 1.091 cmH2O. En las mediciones clínicas también se encontró una alta correlación (r = 0.973; p < 5.46 × 10−13) para la diferencia entre los dos métodos de medición de 0.18, con un intervalo de confianza del 95% de −3.302 a 3.650 mmHg. CONCLUSIONES: Los resultados sugieren que el SDPIA propuesto muestra un desempeño similar al de los transductores de presión actualmente en uso clínico, mientras sobrelleva algunas limitaciones de estos últimos.
