Central line-associated bloodstream infections in patients with COVID-19.

OBJECTIVE: to investigate the association between central line-associated bloodstream infections and clinical and care variables of intensive care unit patients with COVID-19 hospitalized at a reference public health institution. METHOD: a case-control study. RESULTS: the study sample consisted of 70 patients diagnosed with central line-associated bloodstream infections (case group) and 70 non-infected patients (control group). Most patients were male, with mean age of 57.93±13.93 years old and provided with a double lumen catheter. Median time of central line-associated bloodstream infections onset was 11 (8-18) days. Longer time on mechanical ventilation ( P =0.014; OR: 1.79; 95% CI: 0.91-3.51) and prone position ( P =0.017; OR: 2.41; 95% CI: 1.22-4.81) were associated with central line-associated bloodstream infections onset. CONCLUSION: longer time on invasive mechanical ventilation and prone position contributed to central line-associated bloodstream infections onset in COVID-19 patients.

Objetivo: investigar la asociación entre infecciones de la circulación sanguínea relacionadas con catéter venoso central y variables clínicas y asistenciales de pacientes con COVID-19 ingresados en la unidad de cuidados intensivos de una institución pública de salud de referencia. Método: un estudio caso-control. Resultados: la muestra del estudio estuvo compuesta por 70 pacientes con diagnóstico de infección de la circulación sanguínea relacionada con catéter venoso central (grupo caso) y 70 pacientes no infectados (grupo control). La mayoría de los pacientes eran del sexo masculino, con edad media de 57,93±13,93 años y provistos de catéter de doble luz. El tiempo medio de aparición de las infecciones del torrente sanguíneo asociadas a catéter venoso central fue de 11 (8-18) días. Un mayor tiempo en ventilación mecánica ( P =0,014; RP: 1,79; IC 95%: 0,91-3,51) y en posición de decúbito prono ( P =0,017; RP: 2,41; IC del 95 %: 1,22-4,81) se asociaron con la aparición de infecciones de la circulación sanguínea relacionadas con catéter venoso central. Conclusión: un tiempo más prolongado con ventilación mecánica invasiva y posición de decúbito prono contribuyeron a la aparición de infecciones de la circulación sanguínea relacionadas con catéter venoso central en pacientes con COVID-19.

Objetivo: investigar a associação entre infecção primária de corrente sanguínea relacionada a cateter venoso central e variáveis clínicas e assistenciais de pacientes com COVID-19 internados na unidade de terapia intensiva de uma instituição pública de saúde de referência. Método: estudo caso-controle. Resultados: o estudo foi composto por 70 pacientes com diagnóstico de infecção primária de corrente sanguínea relacionada a cateter venoso central (grupo caso) e 70 pacientes sem infecção (grupo controle). Pacientes predominantemente do sexo masculino, média de idade de 57,93±13,93 anos e portadores de cateter de duplo lúmen. A mediana de tempo de ocorrência das infecções primárias de corrente sanguínea relacionadas a cateter venoso central foi de 11 (8-18) dias. Maior tempo em ventilação mecânica ( P =0,014; RP: 1,79; IC 95%: 0,91-3,51) e posição prona ( P =0,017; RP: 2,41; IC 95%: 1,22-4,81) foram associados à ocorrência de infecções primárias de corrente sanguínea relacionadas a cateter venoso central. Conclusão: maior tempo em ventilação mecânica invasiva e posição prona contribuíram para a ocorrência de infecções primárias de corrente sanguínea relacionadas a cateter venoso central em pacientes com COVID-19.

Use of the ADHERE Risk Model as a Predictor of Risk of in-Hospital Worsening Heart Failure in a Cohort. / Uso do Modelo de Risco ADHERE como Preditor de Piora Intra-Hospitalar de Insuficiência Cardíaca em uma Coorte.

BACKGROUND: Patients admitted with acute decompensated heart failure (HF) are subject to developing worsening episodes that require more complex interventions. The Acute Decompensated Heart Failure National Registry (ADHERE) risk model was developed in the United States to predict the risk of in-hospital worsening HF. OBJECTIVE: To use the ADHERE risk model in the assessment of risk of in-hospital worsening HF and to determine its sensitivity and specificity in hospitalized patients. METHODS: This cohort study was conducted at a Brazilian public university hospital, and data from 2013 to 2020 were retrospectively collected. P values < 0.05 were considered statistically significant. RESULTS: A total of 890 patients with a mean age of 74 ± 8 years were included. The model showed that, in the group of 490 patients at risk, 254 (51.8%) developed in-hospital worsening HF. In the group of 400 patients not at risk, only 109 (27.2%) experienced worsening HF. The results demonstrated a statistically significant curve (area under the curve = 0.665; standard error = 0.018; P < 0.01; confidence interval = 0.609 to 0.701), indicating good accuracy. The model had a sensitivity of 69.9% and a specificity of 55.2%, with a positive predictive value of 52% and a negative predictive value of 72.7%. CONCLUSIONS: In this cohort, we showed that the ADHERE risk model was able to discriminate patients who in fact developed worsening HF during the admission period, from those who did not.

MÉTODOS: O presente estudo de coorte foi realizado em um hospital universitário público brasileiro e os dados de 2013 a 2020 foram coletados retrospectivamente. Foram considerados estatisticamente significativos valores de p < 0,05. RESULTADOS: Foram incluídos 890 pacientes com idade média de 74 ± 8 anos. O modelo mostrou que no grupo de 490 pacientes de risco, 254 (51,8%) desenvolveram piora intra-hospitalar da IC. No grupo de 400 pacientes sem risco, apenas 109 (27,2%) apresentaram piora da IC. Os resultados demonstraram uma curva estatisticamente significativa (área sob a curva = 0,665; erro padrão = 0,018; p < 0,01; intervalo de confiança = 0,609 a 0,701), indicando boa precisão. O modelo apresentou sensibilidade de 69,9% e especificidade de 55,2%, com valor preditivo positivo de 52% e valor preditivo negativo de 72,7%. CONCLUSÕES: Na presente coorte, demonstramos que o modelo de predição de risco ADHERE foi capaz de discriminar pacientes que, de fato, desenvolveram piora da IC durante o período de internação daqueles que não desenvolveram.

UltraSound guided PEripheral Catheterization increases first-atTempt success RAte in hospitalized patients when compared with conventional technique: SPECTRA - Randomized Clinical Trial.

BACKGROUND: Peripheral intravenous catheter (PIVC) insertion is the most common invasive procedure in the hospital setting. Ultrasound guided PIVC insertion in specific populations and settings has shown patient care benefits. OBJECTIVE: To compare the success rate of first attempts of ultrasound guided PIVC insertion performed by nurse specialists with conventional PIVC insertion performed by nurse assistants. METHOD: Randomized, controlled, single-center clinical trial registered on the ClinicalTrials.gov platform under registration NTC04853264, conducted at a public university hospital from June to September 2021. Adult patients hospitalized in clinical inpatient units with an indication for intravenous therapy compatible with a peripheral venous network were included. Participants in the intervention group (IG) received ultrasound guided PIVC performed by nurse specialists from the vascular access team, while those in the control group (CG) received conventional PIVC by nurse assistants. RESULTS: The study included a total of 166 patients: IG (n = 82) and CG (n = 84), mean age 59.5 ± 16.5 years, mostly women (n = 104, 62.7%) and white (n = 136, 81.9%). Success rate on the first attempt of PIVC insertion in IG was 90.2% and in CG was 35.7% (p < 0.001), with a relative risk of 2.5 (95% CI 1.88-3.40) for success in IG versus CG. Overall assertiveness rate was 100% in IG and 71.4% in CG. Regarding procedure performance time, the medians in IG and CG were 5 (4-7) and 10 (6-27.5) min respectively (p < 0.001). As for the incidence of negative composite outcomes, IG had lower rates compared to CG, 39% versus 66.7% (p < 0.001), generating a 42% lower probability of negative outcomes in IG, 0.58 (95% CI: 0.43-0.80). CONCLUSION(S): Successful first-try insertion was higher in the group receiving ultrasound-guided PIVC. Moreover, there were no insertion failures and IG presented lower insertion time rates and incidence of unfavorable outcomes.
