Objective:
Routine antibiotic treatment of acute uncomplicated diverticulitis (AUD) has been shown ineffective. In this study, the adherence to a new treatment protocol for uncomplicated diverticulitis was evaluated and the incidence of complications in patients treated with and without antibiotics was investigated.
Materials And Methods:
A retrospective study of in-patients diagnosed with AUD at Helsingborg Hospital, Sweden between 01 January 2013 and 06 January 2015 was performed. Antibiotics were routinely administrated until 01 May 2014. Thereafter, a new antibiotic-free treatment protocol for uncomplicated diverticulitis was introduced. All the patients were followed regarding complications for minimum one year.
Results:
A total of 50 patients were studied after the new protocol implementation and, 60% (n = 31) of the patients were treated without antibiotics. Specialists initiated antibiotic therapy significantly more often than registrars (p=.03). More patients in the antibiotic group had comorbidities (p=.03), apart from that, no significant differences in baseline characteristics were noted between treatment groups. Patients treated with antibiotics after introduction of the new protocol had significantly higher C-reactive protein than patients managed without antibiotics (median 117 mg/L vs. 70, p=.005). The hospital stay was shorter in the non-antibiotic group (three days vs. two days; p=.008). No significant differences in complications were observed.
Conclusions:
Protocol compliance was lower than expected, indicating that implementation of new treatment regimens is challenging. This study confirms that complications are rare in AUD treated without antibiotics. However, the selection of the sickest patients to the treatment with antibiotics limits the interpretation of the results.
Insights
This study found that treating acute uncomplicated diverticulitis (AUD) without antibiotics is safe, with no increase in complications. However, implementing new treatment protocols for AUD can be challenging.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Clinical Medicine
Background:
- Routine antibiotic use for acute uncomplicated diverticulitis (AUD) is often ineffective.
- A new antibiotic-free protocol was introduced to manage AUD.
- Evaluating adherence and complication rates in AUD treatment is crucial.
Purpose of the Study:
- To assess adherence to a new antibiotic-free protocol for AUD.
- To investigate complication incidence in AUD patients treated with and without antibiotics.
- To compare clinical outcomes between antibiotic and non-antibiotic treatment groups for AUD.
Main Methods:
- Retrospective study of 50 in-patients diagnosed with AUD.
- Comparison of patients treated with antibiotics versus an antibiotic-free protocol.
- One-year follow-up for complications in all AUD patients.
Main Results:
- 60% of patients received antibiotic-free treatment under the new protocol.
- Non-antibiotic AUD treatment was associated with a shorter hospital stay (2 vs. 3 days).
- No significant difference in complication rates was observed between groups, though antibiotic group had higher CRP.
Conclusions:
- Protocol compliance for antibiotic-free AUD treatment was lower than anticipated.
- Complications are infrequent in AUD managed without antibiotics.
- Selection bias towards sicker patients for antibiotic treatment complicates result interpretation.
