Clinical characteristics, systemic complications, and in-hospital outcomes for patients with COVID-19 in Latin America. LIVEN-Covid-19 study: A prospective, multicenter, multinational, cohort study.

PURPOSE: The COVID-19 pandemic has spread worldwide, and almost 396 million people have been infected around the globe. Latin American countries have been deeply affected, and there is a lack of data in this regard. This study aims to identify the clinical characteristics, in-hospital outcomes, and factors associated with ICU admission due to COVID-19. Furthermore, to describe the functional status of patients at hospital discharge after the acute episode of COVID-19. MATERIAL AND METHODS: This was a prospective, multicenter, multinational observational cohort study of subjects admitted to 22 hospitals within Latin America. Data were collected prospectively. Descriptive statistics were used to characterize patients, and multivariate regression was carried out to identify factors associated with severe COVID-19. RESULTS: A total of 3008 patients were included in the study. A total of 64.3% of patients had severe COVID-19 and were admitted to the ICU. Patients admitted to the ICU had a higher mean (SD) 4C score (10 [3] vs. 7 [3)], p<0.001). The risk factors independently associated with progression to ICU admission were age, shortness of breath, and obesity. In-hospital mortality was 24.1%, whereas the ICU mortality rate was 35.1%. Most patients had equal self-care ability at discharge 43.8%; however, ICU patients had worse self-care ability at hospital discharge (25.7% [497/1934] vs. 3.7% [40/1074], p<0.001). CONCLUSIONS: This study confirms that patients with SARS CoV-2 in the Latin American population had a lower mortality rate than previously reported. Systemic complications are frequent in patients admitted to the ICU due to COVID-19, as previously described in high-income countries.

Do guidelines change outcomes in ventilator-associated pneumonia?

PURPOSE OF REVIEW: The purpose of the study is to summarize effects of implementation of current and past guidelines for management and treatment of ventilator-associated pneumonia (VAP) on outcome of intensive care patients, with particular focus on etiology of VAP, pathogens prediction, appropriate empiric antibiotic therapy and mortality. RECENT FINDINGS: Several studies have shown that in patients with clinical suspicion of VAP, appropriate antibiotic therapy administered in a timely manner can improve survival. Guidelines for management and treatment of VAP have been developed to help physicians to achieve those goals. Implementation of guidelines into clinical practice is difficult to achieve and requires extensive education for healthcare personnel and translation of recommendations into local protocols. Studies have shown that guidelines implementation is associated with better outcome. However, extensive research needs to be undertaken in order to validate efficacy of guidelines in predicting etiology of pneumonia, in particular, to promptly identify multidrug-resistant pathogens. Only one recent report has validated the latest guidelines and called attention for further research to improve microbial prediction. SUMMARY: Guidelines implementation can improve outcomes. To achieve this goal, guidelines should be adapted to local microbiology, accurately predict VAP pathogens and help physicians to administer the most appropriate empirical antimicrobial therapy.
