ORLANDO – When is it rational to consider de-escalating, or even stopping, antibiotics for septic patients, and how will patients’ future health be affected by antibiotic use during critical illnesses?
According to Jennifer Hanrahan, DO, of Case Western Reserve University, Cleveland, locating the tipping point between optimal care for the individual patient in sepsis, and the importance of antibiotic stewardship is a balancing act. It’s a process guided by laboratory findings, by knowledge of local pathogens and patterns of antimicrobial resistance, and also by clinical judgment, she said at the annual meeting of the Society of Hospital Medicine.
“What is antibiotic stewardship? Most of us think of this as the microbial stewardship police calling to ask you, ‘Why are you using this antibiotic?’’ she said. “It’s really the right antibiotic, for the right diagnosis, for the appropriate duration.”
Of course, Dr. Hanrahan said, any medication is associated with potential adverse events, and antibiotics are no different. “Almost one-third of antibiotics given are either unnecessary or inappropriate,” she said.
Antimicrobial resistance is a very serious public health threat, Dr. Hanrahan affirmed. “Antibiotic use is the most important modifiable factor related to development of antibiotic resistance. With regard to multidrug resistant [MDR] gram negatives, we are running out of antibiotics” to treat these organisms, she said, noting that “Many antibiotics to treat MDRs are “astronomically expensive – and that’s a really big problem.”
It’s important to remember that, when antibiotics are prescribed, “You’re affecting the microbiome not just of that patient, but of those around them,” as resistance factors are potentially spread from one individual’s microbiome to their friends, family, and other contacts, Dr. Hanrahan said.
