JUNE 2023

CDC NARMS Data Available in Sanford Guide App

  • Sanford Guide recently collaborated with the Centers with Disease Control and Prevention to provide convenient access to data collected by the National Antimicrobial Resistance Monitoring System through the Sanford Guide mobile app and web platform. Data are presented in a familiar antibiogram format, alongside a concise metadata document explaining how the data can be interpreted, and with links to other helpful resources from the CDC.
  • CDC data can be added for free through the "Add-Ons" menu in the Sanford Guide app. This collaboration builds upon Sanford Guide's ongoing effort to partner with public health agencies to make public health data more accessible.


US FDA Drug Approvals

  • A co-packaged product containing nirmatrelvir and ritonavir tablets (Paxlovid*) for the treatment of mild-to-moderate COVID-19 in adults who are at high risk for progression to severe disease, including hospitalization or death. Drug manufactured and packaged under the EUA and distributed by DHHS will continue to be available to ensure continued access for adults, as well as treatment of eligible children ages 12-18 who are not covered by the approval. Paxlovid is not approved or authorized for use as a pre-exposure or post-exposure prophylaxis for prevention of COVID-19. See FDA news release here.
  • A co-packaged product containing injectable sulbactam and durlobactam (Xacduro*), for the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of Acinetobacter baumannii-calcoaceticus complex in patients ≥18 years of age. Sulbactam is a beta-lactamase inhibitor with intrinsic activity against Acinetobacter baumannii; durlobactam is a beta-lactamase inhibitor which helps to prevent degradation of sulbactam by enzymes produced by A. baumannii. Recommended dosage in normal renal function is 1 gm of sulbactam and 1 gm of durlobactam IV q6h (infused over three hours). The co-packaged product was granted Priority Review and designated as a Qualified Infectious Disease Product (QIDP). Availability is expected later this year. See FDA news release here.
  • second respiratory syncytial virus (RSV) vaccine (Abrysvo) has been approved for use in individuals 60 years of age and older. This unadjuvanted, bivalent vaccine is composed of equal amounts of recombinant RSV prefusion F protein from RSV subgroups A and B. Dosage is a single 0.5 mL injection. The vaccine will not be released until fall.

AMS Pearl - Clinical Decision Support in Outpatient Settings

  • A recently published study found that implementing clinical decision support tools in the electronic health record was associated with a decrease in antibiotic prescribing. The tools were programmed to trigger when azithromycin or fluoroquinolones were ordered in the emergency department and outpatient clinics of a single institution. In both the emergency department and outpatient clients, monthly rates of azithromycin prescribing decreased significantly (-24% and -47%, respectively). In the clinics, there was no significant drop in the immediate period for ciprofloxacin, but over time, there was a significant decrease (-%5 per month).  
  • Antimicrobial stewardship programs could use the findings from this study to support implementation of clinical decision support tools in emergency departments and outpatient clinics. Antimicrob Steward Healthc Epidemiol. 2023 Apr 26;3(1):e80.
