Role of organisational factors on the 'weekend effect' in critically ill patients in Brazil: a retrospective cohort analysis.

Introduction: Higher mortality for patients admitted to intensive care units (ICUs) during the weekends has been occasionally reported with conflicting results that could be related to organisational factors. We investigated the effects of ICU organisational and staffing patterns on the potential association between weekend admission and outcomes in critically ill patients.

Methods: We included 59 614 patients admitted to 78 ICUs participating during 2013.

Sepsis-Associated Outcomes in Critically Ill Patients with Malignancies.

Rationale: Sepsis is a major cause of mortality among critically ill patients with cancer. Information about clinical outcomes and factors associated with increased risk of death in these patients is necessary to help physicians recognize those patients who are most likely to benefit from ICU therapy and identify possible targets for intervention.

Objectives: In this study, we evaluated cancer patients with sepsis chosen from a multicenter prospective study to characterize their clinical characteristics and to identify independent risk factors associated with hospital mortality.
