News to Note

AMA Journal of Ethics Asks, “Should Physicians Consider the Environmental Effects of Prescribing Antibiotics?”




American Association of Bovine Practitioners Releases Antimicrobial Stewardship Guidelines

JAMA Letter:Peer Benchmarking Helps Primary Care Physicians Maintain Appropriate Prescribing Practices


  • In the 12 months following a randomized study of appropriate antibiotic prescribing in primary care practices, physicians whose study intervention had been peer-to-peer comparison of prescribing practices were observed to maintain lower rates of inappropriate prescribing than a control group.
  • Other study interventions (suggested antibiotic alternatives and inclusion of prescribing justification) did not result in post-study rates significantly different from the control group.


Macrolide Prescribing an Important Target for Antibiotic Stewardship


  • A new publication in Open Forum Infectious Diseasesdescribes macrolide use in outpatient settings during 2008–2011.
  • Co-authors analyzed diagnosis and prescribing data from the National Ambulatory Medical Care Survey, finding that conditions for which macrolides are first-line therapy only accounted for 5% of macrolide prescribing.
  • Diagnoses most commonly associated with macrolide prescriptions were sinusitis (18% of visits), bronchitis/bronchiolitis (14%), viral upper respiratory infection (11%), and pharyngitis (11%), for which macrolides are not recommended first-line therapy.
  • Prescribing varied by specialty, with family practitioners selecting macrolides for children more frequently than pediatricians.


Community-AcquiredClostridium difficileand Antibiotic Prescribing for Dental Procedures

  • In a2017 IDWeek abstract, Minnesota Department of Health reports that 926/1,626 (57%) people with community-associatedC. difficileinfection during 2009–2015 reported taking a course of antibiotics prior to illness.
  • 136 (15%) of patients received the prescription for a dental procedure.
  • In 34% of cases, the dental antibiotics were not recorded in primary medical records,highlighting a gap in information sharing across care settings.
  • Dentists are partners in antibiotic stewardship and should be included in efforts to improve prescribing. Minnesota’s Dental Association, Board of Dentistry and One Health Antibiotic Stewardship Collaborative have joined to develop anantibiotic sheet for dental professionals.

Cochrane Systematic Review Describes Safety of Procalcitonin-Guided Antibiotic Treatment


  • Procalcitonin, a blood marker associated with bacterial infection, is used as a clinical tool to support initiation and de-escalation of antibiotic therapy.
  • Results of aCochrane meta-analysisshow that 30-day mortality and duration of antibiotic therapy were significantly lower among patients receiving procalcitonin-guided therapy than among control patients.

Quiz Answer!

b. Methicillin-resistant S. pseudointermedius (MRSP)

Quiz Icon


Methicillin-resistantStaphylococcus aureus(MRSA) is of great concern to human health, with serious infections originating in the community and in healthcare settings. MRSA has also been identified in diagnostic specimens from dogs and cats (“companion animals”), but it is not a frequent cause of clinical infection. In fact, MRSA found on our companion animals might actually be transferred from humans carrying thebacteria(Morris 2006). A growing clinical problem in companion animal veterinary medicine is Methicillin-resistantStaphylococcus pseudointermedius(MRSP; Lloyd 2012). S. pseudointermedius is a major cause of canine pyoderma, and risk factors for canine MRSP colonization include hospitalization and antibiotic treatment (Nienhoff 2011). In one UK laboratory study, MRSP made up 14% of coagulase-positive canine staphylococci isolates (Steen 2010). A recent Canadian study ofS. pseudointermediusin dogs found that 78/100 were colonized, and that the frequency of colonization with pan-susceptible isolates decreased from 46% to 30% of colonized dogs. (Priyantha 2016). Resistance was highest to penicillin, ampicillin, tetracycline, oxacillin, erythromycin, clindamycin, and trimethoprim-sulfamethoxazole. Multidrug resistance (resistance to three or more drug classes) was found in 15/221 (6.8%)S. pseudointermediusisolates.
