It takes a village: decreasing inappropriate antibiotic prescribing for upper respiratory tract infections.

Objective: Prescribing of antibiotics for viral upper respiratory infections (URIs) remains a pressing public health problem. We sought to reduce inappropriate prescribing of antibiotics for URIs in Mayo Clinic Arizona.

Design: Single-center, quasi-experimental, and retrospective cohort study.

Association of Neutralizing Antispike Monoclonal Antibody Treatment With Coronavirus Disease 2019 Hospitalization and Assessment of the Monoclonal Antibody Screening Score.

Objective: To test the hypothesis that the Monoclonal Antibody Screening Score performs consistently better in identifying the need for monoclonal antibody infusion throughout each "wave" of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant predominance during the coronavirus disease 2019 (COVID-19) pandemic and that the infusion of contemporary monoclonal antibody treatments is associated with a lower risk of hospitalization.

Patients And Methods: In this retrospective cohort study, we evaluated the efficacy of monoclonal antibody treatment compared with that of no monoclonal antibody treatment in symptomatic adults who tested positive for SARS-CoV-2 regardless of their risk factors for disease progression or vaccination status during different periods of SARS-CoV-2 variant predominance. The primary outcome was hospitalization within 28 days after COVID-19 diagnosis.

Two masks can be worse than one: N95 respirator failure caused by an overlying face mask.

We have demonstrated the effect of covering an N95 filtering facepiece respirator (FFR) with an overlying face mask. In total, 100 participants successfully completed quantitative fit testing wearing a 3M 1870+ FFR. Among them, 13 (13%; 95% CI, 7%-22%) failed subsequent fit testing when simultaneously wearing a Halyard 47117 procedural mask over the FFR.

Standardizing central line safety: lessons learned for physician leaders.

A comprehensive central venous catheter (CVC) safety program reduces mechanical and infectious complications and requires an integrated multidisciplinary effort. A multistate health care system implemented a discovery and diffusion project addressing CVC insertion, maintenance, and removal. Process and outcome measures were collected before and after the intervention.

2009 H1N1 influenza in hospitalized transplant recipients.

Background: The 2009 H1N1 influenza virus was first identified in April 2009 and rapidly evolved into a pandemic. There are limited reports of 2009 H1N1 influenza in transplant recipients. We report on our experience with hospitalized transplant recipients with 2009 H1N1 influenza virus.
