Update confirms best practices
“Concerns about inappropriate antimicrobial therapy use and the delay in seeking preventative care such as a colonoscopy have led to poorer outcomes for patients,” ACP president George Abraham, MD, said in an interview. These concerns about a lack of antimicrobial stewardship and of care not being representative of ‘high value care’ “supported the need to reinforce best practices.”

Although most clinicians are aware of the nature of the recommendations in their own clinical practices, “a systematic review helped confirm and codify best practice that everyone can confidently incorporate into their daily decision-making,” Dr. Abraham said.
Compared with previous guidelines, “the single biggest difference is the fact that antimicrobial therapy is not indicated in mild, uncomplicated diverticulitis; we hope this will lead to lesser and more judicious antimicrobial prescribing,” Dr. Abraham emphasized.
Like all guidelines, the current guidelines are meant to be advisory, not mandatory; “they do not replace good clinical judgment and individual patient care decision-making,” Dr. Abraham said. “These guidelines are useful when they are widely read by clinicians, including physicians and advanced practice clinicians, and incorporated into their daily practice.”
Curbing antibiotic use
It is important for clinicians to recognize that uncomplicated diverticulitis in selected patients does not require initial antibiotics, David A. Johnson, MD, chief of gastroenterology at Eastern Virginia School of Medicine, Norfolk, said in an interview. “This paradigm shift began with the AGA guidelines in 2015, and was more recently updated with the 2021 best practice recommendations,” first published in Gastroenterology.
“I was surprised to see this current guideline not mentioning that, if antibiotics are to be used, that amoxicillin-clavulanate alone should be favored over combination of fluoroquinolones and metronidazole,” Dr. Johnson noted. “Furthermore, the U.S. Food and Drug Administration has advised that fluoroquinolones should be reserved for conditions with no alternative treatment options.”
“The initial management approach for the AGA guidelines and best practice are comparable with these most recent ACP recommendations,” said Dr. Johnson. However, “I would suggest that clinicians treating diverticulitis also review the AGA best practice recommendations, which build out important other important points for diverticulitis management including timeframes for colonoscopy, strong effect of genetics, dietary effects, recurrence rates, and the role of surgery.”
As for research gaps, “further data on cost savings would be helpful,” as savings may be likely with significant reduction without antibiotics and imaging in select patients, Dr. Johnson said. “Cost savings and risk reduction of adverse implications of antibiotic and radiation risks should be included in these analyses.”
The guidelines were based on systematic reviews conducted by the Evidence-based Practice Center at Brown University, Providence, R.I., funded by the Agency for Healthcare Research and Quality. The development of the guidelines was supported by the ACP operating budget. The authors, Dr. Abraham, and Dr. Johnson had no financial conflicts to disclose.
