INTRODUCTION: Diverticulitis and appendicitis are common emergency general surgical conditions. Both can be treated with antibiotics alone; however, no antibiotic regimen has been identified as superior to others. In this study, we review different antibiotic regimens and their rates of failure.
METHODS: Retrospective cohort study of patients treated empirically with antibiotics for diverticulitis or appendicitis from January 1, 2018, to December 31, 2020, at an independent academic hospital in the Midwest.
RESULTS: A total of 587 (appendicitis, n = 43; diverticulitis, n = 544) patients were included in the cohort. They were equally male (49%) and female (51%) with a median age of 59 y. Three major antibiotic classes were compared: cephalosporin + metronidazole (C + M), penicillins, and quinolone + metronidazole. Appendicitis patients were more likely to receive C + M for empiric treatment (73%, P < 0.001), while diverticulitis patients were more likely to receive quinolone + metronidazole (45%, P < 0.001). Patients empirically treated with antibiotics for appendicitis were more likely than those treated for diverticulitis to require additional antibiotics or procedure within 90 d (33% versus 13%, respectively; P = 0.005). Empiric treatment with C + M for diverticulitis was more likely to be associated with the need for additional antibiotics or procedures within 90 d than treatment with other regimens (P = 0.003). Choice of antibiotic for empiric treatment did not correlate with death at 90 d for appendicitis or diverticulitis. Diverticulitis patients who were initially treated as inpatients and were prescribed C + M at hospital discharge had a higher rate of death than those who were prescribed the other antibiotics (P = 0.04).
CONCLUSIONS: Empiric antibiotic treatment of appendicitis is more likely to be associated with additional antibiotics or procedure when compared with diverticulitis; however, antibiotic choice did not correlate with any of the other outcomes. Empiric treatment with a C + M for diverticulitis was more likely to be correlated with the need for additional antibiotics or procedure within 90 d.
