The challenge of infectious diseases consultations in the emergency department: an Italian nationwide survey.

Diagnosis and management of infectious diseases (ID) at the emergency department (ED) are challenging due to the peculiar setting and the available diagnostic tools. The involvement of an ID consultant has been described to improve clinical outcomes and antimicrobial stewardship (AMS) programs. An online survey was sent to 100 Italian Departments of Infectious Diseases affiliated with the Italian Society of Infectious Diseases and Tropical Medicine (SIMIT). The primary objective of our study was to describe the characteristics of ID services in Italian EDs to identify possible challenges and shortcomings and provide tips to improve the management of patients. Secondary objectives included the evaluation of diagnostic capability and the management of patients with suspected or confirmed ID. Seventy-six out of the 100 SIMIT centers, 32 (42.1%) of which were teaching hospitals, answered the survey. In 62 (82.7%) centers, consultations were performed by the IDs specialist on call. In 29 (38.2%) centers, there was a formal AMS program, and 32 (42.7%) had protocols for antibiotic use in the ED. Microbiological tests to be performed before starting antibiotic treatment in the ED were clearly defined in 44 (57.9%) hospitals. This survey highlighted several challenges in the current organization of ID consultations in Italian EDs.
