SARS-CoV-2 / COVID-19

CDC Syphilis Testing Recommendations

  • Approximately six million new cases of syphilis occur globally each year. A syphilis epidemic is occurring in the US, with sustained increases in primary and secondary syphilis from 5,979 cases reported in 2000 to 133,945 cases reported in 2020. This epidemic is characterized by health disparities, particularly among sexual and gender minority populations, intersections with the HIV and substance use epidemics, and increased morbidity and mortality due to congenital infection. The US CDC has published new recommendations for syphilis testing, including laboratory-based tests, point-of-care tests, processing of samples, and reporting of test results (MMWR Recomm Rep 2024;73(1):1-35).

AMS Pearl: ABX Order Sets & Use Metrics

  • A recent study assessed the impact of electronic antibiotic order sets on antibiotic use over a 5-year period at a single academic medical center. Order sets were developed and deployed in the electronic medical record for the empiric treatment of community-acquired pneumonia, urinary tract infection, skin and soft-tissue infection, and others. The antibiotic recommendations were based on national guidelines, the local antibiogram, and the hospital formulary.
  • There was a significant decrease in the Standardized Antibiotic Administration Ratio (SAAR) from phase 1 to phase 5 driven largely by a reduction in broad-spectrum agents used for hospital-onset infections. There was also a significant decrease in the days of therapy per 1,000 patient days, fluoroquinolone orders, carbapenem orders, and clindamycin orders.
  • Antimicrobial stewardship programs could use the findings from this study to support the development of electronic antibiotic order sets. Infect Control Hosp Epidemiol. 2024;doi: 10.1017/ice.2023.293.
