A study in the United States found that despite lower admission rates, the incidence of diverticulitis in emergency departments increased from 0.4% in 2016 to 0.56% in 2023. CT scans were performed in 89.6% of cases, with an increase in usage from 83% to 92.6% over time. Admission rates for diverticulitis patients decreased from 33.6% to 27.7%, with a shift towards using penicillin-based antibiotics over fluoroquinolones and metronidazole. The study highlights the importance of considering the risks and benefits when deciding on CT imaging for diverticulitis cases. The findings were published in The American Journal of Emergency Medicine.
