We describe laboratory-confirmed influenza A pandemic (H1N1) 2009 in 17 hospitalized recipients of a hematopoietic stem cell transplant (HSCT) (8 allogeneic) and 15 patients with malignancy treated at 6 Australian tertiary centers during winter 2009. Ten (31.3%) were admitted to intensive care, 9 them HSCT recipients. All allogeneic infection <100 days posttransplantation or severe graft-versus-host disease an care unit. In-hospital mortality rate was 21.9% (7/32). The H275Y neuraminidase...

Introduction A pandemic coronavirus, SARS-CoV-2, causes COVID-19, a potentially life-threatening respiratory disease. Patients with cancer may have compromised immunity due to their malignancy and/or treatment, and be at elevated risk of severe COVID-19. Community transmission COVID-19 could overwhelm health care services, compromising delivery care. This interim consensus guidance provides advice for clinicians managing patients during the pandemic. Main recommendations During pandemic: In...

Summary An integrated antibiotic allergy testing program resulted in increased prescribing of narrow-spectrum β-lactams and reduction restricted antibiotics inappropriate prescriptions. The effectively safely de-labeled patients, with &gt;80% labels removed following testing.

To compare risks for developing surgical site infection (SSI) due to Staphylococcus aureus when vancomycin is used antibiotic prophylaxis with a β-lactam administered prophylaxis.Vancomycin often as major surgery. In nonsurgical populations, there evidence that less effective prevention and treatment of methicillin-sensitive (MSSA) infections. Since 2002, the Victorian Healthcare Associated Surveillance System (VICNISS) has standardized methods surveillance in Australia, including any...

Antibiotic allergy testing (AAT) practices of Emerging Infections Network infectious disease physicians were surveyed. Although AAT was perceived to be necessary for removal inappropriate or unnecessary labels, there limited access any form testing. In this study, we discuss current antibiotic knowledge gaps and the development within antimicrobial stewardship programs, which will potentially improve prescribing.
