A Needs Assessment for Infectious Diseases Consultation in Community Hospitals.

INTRODUCTION: Infectious diseases (ID) consultations have been demonstrated to improve patient outcomes in the treatment of severe infections. However, ID consultation is often unavailable to patients that live in rural communities. Little is known regarding the treatment of infections in rural hospitals with no coverage from an ID specialist. We characterized the outcomes of patients cared for in hospitals without coverage from an ID physician. METHODS: Patients aged 18 years or older admitted to eight community hospitals without access to ID consultation during a 6.5-month period were assessed. All patients had received at least three days of continuous antimicrobial therapy. The primary outcome was the need for transfer to a tertiary facility for ID services. The secondary outcome was the characterization of antimicrobials received. Antimicrobial courses were evaluated independently by two board-certified ID physicians. RESULTS: 3706 encounters were evaluated. Transfers for ID consultation occurred in 0.01% of patients. The ID physician would have made modifications in 68.5% of patients. Areas for improvement included treatment of chronic obstructive pulmonary disease exacerbations, broad-spectrum treatment of skin and soft tissue infection, long courses of azithromycin, and management of Staphylococcus aureus bacteremia, including choice and length of therapy, as well as obtaining echocardiography. Patients evaluated received 22,807 days of antimicrobial therapy. CONCLUSIONS: Patients hospitalized in community hospitals are rarely transferred for ID consultation. Our work demonstrates a need for ID consultation in community hospitals, identifying opportunities to enhance patient care by modifying antimicrobial regimens to improve antimicrobial stewardship and avoid inappropriate antimicrobials. Efforts to expand the ID workforce to include coverage at rural hospitals will likely improve antibiotic utilization.

Cardiac Magnetic Resonance Imaging for the Diagnosis of Infective Endocarditis in the COVID-19 Era.

In the COVID-19 pandemic, to minimize aerosol-generating procedures, cardiac magnetic resonance imaging (CMR) was utilized at our institution as an alternative to transesophageal echocardiography (TEE) for diagnosing infective endocarditis (IE). This retrospective study evaluated the clinical utility of CMR for detecting IE among 14 patients growing typical microorganisms on blood cultures or meeting modified Duke Criteria. Seven cases were treated for IE. In 2 cases, CMR results were notable for possible leaflet vegetations and were clinically meaningful in guiding antibiotic therapy, obtaining further imaging, and/or pursuing surgical intervention. In 2 cases, vegetations were missed on CMR but detected on TEE. In 3 cases, CMR was non-diagnostic, but patients were treated empirically. There was no difference in antibiotic duration or outcomes over 1 year. CMR demonstrated mixed results in diagnosing valvular vegetations and guiding clinical decision-making. Further prospective controlled trials of CMR Vs TEE are warranted.
