European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines for Antimicrobial Stewardship in Emergency Departments (endorsed by European Association of Hospital Pharmacists). Clin Microbiol Infect 2024:S1198-743X(24)00251-9. [PMID: 39029872 DOI: 10.1016/j.cmi.2024.05.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 05/24/2024] [Accepted: 05/26/2024] [Indexed: 07/21/2024]
Abstract
SCOPE This ESCMID guideline provides evidence-based recommendations to support a selection of appropriate antibiotic use practices for patients seen in the emergency department (ED) and guidance for their implementation. The topics addressed in this guideline are: 1) Do biomarkers or rapid pathogen tests improve antibiotic prescribing and/or clinical outcomes? 2) Does taking blood cultures in common infectious syndromes improve antibiotic prescribing and/or clinical outcomes? 3) Does watchful waiting without antibacterial therapy or with delayed antibiotic prescribing reduce antibiotic prescribing without worsening clinical outcomes in patients with specific infectious syndromes? 4) Do structured culture follow-up programs in patients discharged from the ED with cultures pending improve antibiotic prescribing? METHODS An expert panel was convened by ESCMID and the guideline chair. The panel selected in consensus the four most relevant AMS topics according to pre-defined relevance criteria. For each main question for the four topics, a systematic review was performed, including randomized controlled trials and observational studies. Both clinical outcomes as well as stewardship process outcomes related to antibiotic use were deemed relevant. The literature searches were conducted between May 2021 and March 2022. In April 2022, the panel members were formally asked to suggest additional studies that were not identified in the initial searches. Data were summarized in a meta-analysis if possible or otherwise summarized narratively. The certainty of the evidence was classified according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. The guideline panel reviewed the evidence per topic critically appraising the evidence and formulated recommendations through a consensus-based process. The strength of the recommendations was classified as strong or weak. To substantiate the implementation process, implementation trials or observational studies describing facilitators/barriers for implementation were identified from the same searches and were summarized narratively. RECOMMENDATIONS The recommendations on the use of biomarkers and rapid pathogen diagnostic tests focus on the initiation of antibiotics in patients admitted through the ED. Their effect on the discontinuation or de-escalation of antibiotics during hospital stay was not reported, neither was their effect on hospital infection prevention and control practices. The recommendations on watchful waiting (i.e., withholding antibiotics with some form of follow-up) focus on specific infectious syndromes for which the primary care literature was also included. The recommendations on blood cultures focus on the indication in three common infectious syndromes in the ED explicitly excluding patients with sepsis or septic shock. Most recommendations are based on very-low- and low-certainty of evidence, leading to weak recommendations or, when no evidence was available, to best practice statements. Implementation of these recommendations needs to be adapted to the specific settings and circumstances of the ED. The scarcity of high-quality studies in the area of antimicrobial stewardship in the ED highlights the need for future research in this field.

Abstract
Colonic diverticulosis is prevalent, affecting approximately 70% of the western population by 80 years of age. Incidence is rapidly increasing in younger age groups. Between 10% and 25% of those with diverticular disease (DD) will experience acute diverticulitis. A further 15% will develop complications including abscess, bleeding and perforation. Such complications are associated with significant morbidity and mortality and constitute a worldwide health burden. Furthermore, chronic symptoms associated with DD are difficult to manage and present a further significant healthcare burden. The pathophysiology of DD is complex due to multifactorial contributing factors. These include diet, colonic wall structure, intestinal motility and genetic predispositions. Thus, targeted preventative measures have proved difficult to establish. Recently, commonly held conceptions on DD have been challenged. This review explores the latest understanding on pathophysiology, risk factors, classification and treatment options.

Abstract
Objective We aimed to describe epidemiologic trends in outcomes of colonic diverticular disease (CDD) hospitalizations in morbidly obese patients. Methods We searched the United States National Inpatient Sample databases from 2010 through 2019, obtained the incidence rate of morbid obesity (MO) among CDD hospitalizations, and used Joinpoint analysis to obtain trends in these rates adjusted for age and sex. Hospitalizations involving patients less than 18 years of age were excluded. Trends in mortality rate, mean length of hospital stay (LOS), and mean total hospital charge were analyzed. Multivariate regression analysis was used to obtain trends in adjusted mortality, mean LOS, and mean total hospital charge. Results We found an average annual percent change of 7.5% (CI = 5.5-9.4%, p < 0.01) in the adjusted incidence of MO among hospitalizations for CDD over the study period. We noted a 7.2% decline in mortality (p = 0.011) and a 0.1 days reduction in adjusted LOS (p < 0.001) over the study period. Hospitalizations among the middle-aged and elderly had adjusted odds ratios of 7.18 (95% CI = 2.2-23.3, p = 0.001) and 24.8 (95% CI = 7.9-77.9, p < 0.001), respectively, for mortality compared to those in young adults. The mean LOS was 0.29 days higher in females compared to males (p < 0.001). Conclusion The incidence of MO increased among CDD hospitalizations while mortality and mean LOS reduced over the study period. Outcomes were worse in older patients, with an increased mean LOS in females compared to males.

Abstract
BACKGROUND Diverticulitis is a complication of the common condition, diverticulosis. Uncomplicated diverticulitis has traditionally been treated with antibiotics, as diverticulitis has been regarded as an infectious disease. Risk factors for diverticulitis, however, may suggest that the condition is inflammatory rather than infectious which makes the use of antibiotics questionable. OBJECTIVES The objectives of this systematic review were to determine if antibiotic treatment of uncomplicated acute diverticulitis affects the risk of complications (immediate or late) or the need for emergency surgery. SEARCH METHODS For this update, a comprehensive systematic literature search was conducted in Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, ClinicalTrials.gov and WHO International Clinical Trial Registry Platform on February 2021. SELECTION CRITERIA Randomised controlled trials (RCTs), including all types of patients with a radiologically confirmed diagnosis of left-sided uncomplicated acute diverticulitis. Comparator and interventions included antibiotics compared to no antibiotics, placebo, or to any other antibiotic treatment (different regimens, routes of administration, dosage or duration of treatment). Primary outcome measures were complications and emergency surgery. Secondary outcomes were recurrence, late complications, elective colonic resections, length of hospital stay, length to recovery of symptoms, adverse events and mortality. DATA COLLECTION AND ANALYSIS Two authors performed the searches, identification and assessment of RCTs and data extraction. Disagreements were resolved by discussion or involvement of the third author. Authors of trials were contacted to obtain additional data if needed or for preliminary results of ongoing trials. The Cochrane Collaboration's tool for assessing risk of bias was used to assess the methodological quality of the identified trials. The overall quality of evidence for outcomes was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Effect estimates were extracted as risk ratios (RRs) with 95% confidence intervals. Random-effects meta-analyses were performed with the Mantel-Haenzel method. MAIN RESULTS The authors included five studies. Three studies compared no antibiotics to antibiotics; all three were original RCTs of which two also published long-term follow-up information. For the outcome of short-term complications there may be little or no difference between antibiotics and no antibiotics (RR 0.89; 95% CI 0.30 to 2.62; 3 studies, 1329 participants; low-certainty evidence). The rate of emergency surgery within 30 days may be lower with no antibiotics compared to antibiotics (RR 0.47; 95% CI 0.13, 1.71; 1329 participants; 3 studies; low-certainty evidence). However, there is considerable imprecision due to wide confidence intervals for this effect estimate causing uncertainty which means that there may also be a benefit with antibiotics. One of the two remaining trials compared single to double compound antibiotic therapy and, due to wide confidence intervals, the estimate was imprecise and indicated an uncertain clinical effect between these two antibiotic regimens (RR 0.70; 95% CI 0.11 to 4.58; 51 participants; 1 study; low-certainty evidence). The last trial compared short to long intravenous administration of antibiotics and did not report any events for our primary outcomes. Both trials included few participants and one had overall high risk of bias. Since the first publication of this systematic review, an increasing amount of evidence supporting the treatment of uncomplicated acute diverticulitis without antibiotics has been published, but the total body of evidence is still limited. AUTHORS' CONCLUSIONS The evidence on antibiotic treatment for uncomplicated acute diverticulitis suggests that the effect of antibiotics is uncertain for complications, emergency surgery, recurrence, elective colonic resections, and long-term complications. The quality of the evidence is low. Only three RCTs on the need for antibiotics are currently available. More trials are needed to obtain more precise effect estimates.

Observational versus antibiotic therapy for acute uncomplicated diverticulitis: A non-inferiority meta-analysis based on a Delphi consensus. Surgery 2022; 171:328-335.

Abstract
BACKGROUND The purpose of this study was to determine if observational therapy is noninferior to antibiotics for acute uncomplicated diverticulitis according to clinically relevant margins. METHODS MEDLINE, EMBASE, and Cochrane were systematically searched by 2 independent reviewers to identify comparative studies of observational therapy versus antibiotics for acute uncomplicated diverticulitis. Non-inferiority margins (ΔNI) for each outcome were based on Delphi consensus including 50 patients and 55 physicians: persistent diverticulitis (ΔNI = 4.0%), progression to complicated diverticulitis (ΔNI = 3.0%), and time to recovery (ΔNI = 5 days). Risk differences and mean differences were pooled using random-effects meta-analysis. One-sided 90% confidence intervals and Z-tests were used to determine non-inferiority. A sensitivity analysis was performed, excluding patients post hoc determined to have complicated diverticulitis. RESULTS Nine studies (3 randomized controlled trials, 6 observational studies) met inclusion criteria: observational therapy (n = 2,011) versus antibiotics (n = 1,144). Observational therapy was noninferior to antibiotics regarding the risk of persistent diverticulitis (pooled risk differences: -0.39%, 90% CI -3.22 to 2.44%, ΔNI: 4.0%, PNI < 0.001; I2 = 66%) and progression to complicated diverticulitis (pooled risk differences: -0.030%, 90% CI -0.99 to 0.92%, ΔNI: 3.0%, PNI < 0.001; I2 = 0%). On sensitivity analysis, observational therapy remained noninferior for both outcomes. When stratified by study design, observational therapy also remained noninferior for both outcomes among randomized controlled trials only. Only 1 study reported on time to recovery as a continuous outcome, with no statistical difference between antibiotics and observational therapy. CONCLUSION According to clinically relevant ΔNIs, observational therapy was noninferior to antibiotics for the treatment of acute uncomplicated diverticulitis with regard to persistent diverticulitis and progression to complicated diverticulitis.

Abstract
Left-sided colonic diverticulitis is a common condition with significant morbidity and health care costs in Western countries. Acute uncomplicated diverticulitis which is characterized by the absence of organ dysfunction, abscesses, fistula, or perforations accounts for around 80% of the cases. In the last decades, several traditional paradigms in the management of acute uncomplicated diverticulitis have been replaced by evidence-based routines. This review provides a comprehensive evidence-based and clinical-oriented overview of up-to-date diagnostics with computer tomography, non-antibiotic treatment, outpatient treatment, and surgical strategies as well as follow-up of patients with acute uncomplicated diverticulitis.

Abstract
Left sided colonic diverticulitis is a common and costly gastrointestinal disease in Western countries, characterized by acute onset of often severe abdominal pain. Imaging is necessary to make an initial diagnosis and determine disease severity. Colonoscopy should be done six to eight weeks after diagnosis to rule out a missed colon malignancy. Antibiotic treatment is used selectively in immunocompetent patients with mild acute uncomplicated diverticulitis. The clinical course of diverticulitis commonly includes unpredictable recurrences and chronic gastrointestinal symptoms, which are a detriment to quality of life. A better understanding of prognosis has prompted a shift toward non-operative approaches. The decision to undergo prophylactic colon resection should be individualized to consider the severity of diverticulitis, the patient's health and immune status, and the patient's preferences and values, as well as benefits and risks. Because only a section of colon is removed, recurrent diverticulitis remains a risk. Acute diverticulitis with an abscess is treated with antibiotics that cover Gram negative and anaerobic bacteria, with or without percutaneous drainage. Acute diverticulitis with purulent or feculent contamination of the peritoneal cavity is managed with surgery; primary resection and anastomosis is the procedure of choice in stable patients.

Abstract
BACKGROUND Despite the existing evidence, the omission of antibiotics in the management of acute uncomplicated diverticulitis has not gained widespread acceptance. OBJECTIVE This study aims to incorporate the input of both patients and physicians on the omission of antibiotics in uncomplicated diverticulitis to generate noninferiority margins for 3 outcomes. DESIGN This was a mixed-methods study, including in-person interviews with patients and a Delphi process with physicians. SETTINGS North American patients and physicians participated. PATIENTS Consecutive patients undergoing colonoscopy, 40% of whom had a previous history of diverticulitis, were selected. INTERVENTIONS Informational video (for patients) and evidence summaries (for physicians) regarding antibiotics in diverticulitis were reviewed. MAIN OUTCOMES MEASURES Noninferiority margins were generated for time to reach full recovery, persistent diverticulitis, and progression to complicated diverticulitis in the context of a nonantibiotic strategy. Consensus was defined as an interquartile range <2.5. RESULTS Fifty patients participated in this study. To avoid antibiotics, patients were willing to accept up to 5.0 (3.0-7.0) days longer to reach full recovery, up to an absolute increase of 4.0% (4.0-6.0) in the risk of developing persistent diverticulitis, and up to an absolute increase of 2.0% (0-3.8) in the risk of progressing to complicated diverticulitis. A total of 55 physicians participated in the Delphi (round 1 response rate = 94.8%; round 2 response rate = 100%). Consensus noninferiority margins were generated for persistent diverticulitis (4.0%, 4.0-5.0) and progression to complicated diverticulitis (3.0%, 2.0-3.0), but could not be generated for time to reach full recovery (5.0 days, 3.5-7.0). LIMITATIONS Patients were recruited from a single institution, and Delphi participants were invited and not randomly selected. CONCLUSION Noninferiority margins were generated for 3 important outcomes after the treatment of acute uncomplicated diverticulitis in the context of a nonantibiotic strategy.

Abstract
BACKGROUND/AIMS Currently, right colonic uncomplicated diverticulitis is typically treated with antibiotic therapy. However, the optimal duration of treatment is unknown. The aim of the present study was to compare the treatment failure rates between 1- and 4-day antibiotic treatment protocols. MATERIALS AND METHODS A prospective randomized study in adults presenting with uncomplicated diverticulitis at the first episode from July 2011 to June 2014 was performed. Patients were randomized to receive intravenous antibiotics for 1 day (1-day group) or intravenous and oral antibiotics for 4 days (4-day group). All patients received cefmetazole and metronidazole. Treatment failure was defined as readmission within 30 days and disease recurrence during the follow-up period. RESULTS Overall, 87 and 89 patients were randomized to the 1-day and 4-day groups, respectively. All patients were successfully treated initially. The hospital length of stay was shorter in the 1-day group than in the 4-day group (3.1 vs. 3.8 days, respectively; p<0.001). After discharge, there were no significant differences between the groups in treatment failure (15/87, 17.2% vs. 19/89, 21.3%; p=0.493). In each group, there were readmission within 30 days (9.2% vs. 12.4%; p=0.502) and recurrence over a median follow-up period of 32 months (10.3% vs. 9.0%; p=0.762). In 34 patients who experienced treatment failure, 6 required surgery. CONCLUSION Single-day antibiotic treatment is as effective as 4-day therapy for the prevention of readmission and recurrence in patients with right colonic uncomplicated diverticulitis.

Abstract
BACKGROUND Despite low-quality and conflicting evidence, the Association of Coloproctology of Great Britain and Ireland recommends the routine use of antibiotics in the treatment of uncomplicated acute diverticulitis. Recent studies have shown that treatment without antibiotics did not prolong recovery. Some new guidelines currently recommend selective use of antibiotics. OBJECTIVE The purpose of this study was to compare the safety, effectiveness, and outcomes in treating uncomplicated acute diverticulitis without antibiotics with treatment with antibiotics. DATA SOURCES PubMed, Embase, Clinicaltrials.gov, and the Cochrane Library were searched with the key words antibiotics and diverticulitis. STUDY SELECTION All studies published in English on treating uncomplicated acute diverticulitis without antibiotics and containing >20 individuals were included. INTERVENTION Treatment without antibiotics versus treatment with antibiotics were compared. MAIN OUTCOME MEASURES The primary outcome was the percentage of patients requiring additional treatment or intervention to settle during the initial episode. The secondary outcomes were duration of hospital stay, rate of readmission or deferred admission, need for surgical or radiological intervention, recurrence, and complication. RESULTS Search yielded 1164 studies. Nine studies were eligible and included in the meta-analysis, composed of 2505 patients, including 1663 treated without antibiotics and 842 treated with an antibiotic. The no-antibiotics group had a significantly shorter hospital stay (mean difference = -0.68; p = 0.04). There was no significant difference in the percentage of patients requiring additional treatment or intervention to settle during the initial episode (5.3% vs 3.6%; risk ratio = 1.48; p = 0.28), rate of readmission or deferred admission (risk ratio = 1.17; p = 0.26), need for surgical or radiological intervention (risk ratio = 0.61; p = 0.34), recurrence (risk ratio = 0.83; p = 0.21), and complications (risk ratio = 0.70-1.18; p = 0.67-0.91). LIMITATIONS Only a limited number of studies were available, and they were of variable qualities. CONCLUSIONS Treatment of uncomplicated acute diverticulitis without antibiotics is associated with a significantly shorter hospital stay. There is no significant difference in the percentage of patients requiring additional treatment or intervention to settle in the initial episode, rate of readmission or deferred admission, need for surgical or radiological intervention, recurrence, or complications.

Abstract
BACKGROUND Antibiotics are routinely used for diverticulitis irrespective of severity. Current practice guidelines favor against the use of antibiotics for acute uncomplicated diverticulitis. OBJECTIVE We performed a systematic review and meta-analysis to examine the role of antibiotic use in an episode of uncomplicated diverticulitis. DATA SOURCES PubMed/Medline, Embase, Scopus, and Cochrane were used. STUDY SELECTION Eligible studies included those with patients with uncomplicated diverticulitis receiving any antibiotics compared with patients not receiving any antibiotics (or observed alone). MAIN OUTCOME MEASURES Pooled odds rate of total complications, treatment failure, recurrent diverticulitis, readmission rate, sigmoid resection, mortality rate, and length of stay were measured. RESULTS Of 1050 citations reviewed, 7 studies were eligible for the analysis. There were total of 2241 patients: 895 received antibiotics (mean age = 59.1 y; 38% men) and 1346 did not receive antibiotics (mean age = 59.4 y; 37% men). Antibiotics were later added in 2.7% patients who initially were observed off antibiotics. Length of hospital stay was not significantly different among either group (no antibiotics = 3.1 d vs antibiotics = 4.5 d; p = 0.20). Pooled rate of recurrent diverticulitis was not significantly different among both groups (pooled OR = 1.27 (95%, CI 0.90-1.79); p = 0.18). Rate of total complications (pooled OR = 1.99 (95% CI, 0.66-6.01); p = 0.22), treatment failure (pooled OR = 0.68 (95% CI, 0.42-1.09); p = 0.11), readmissions (pooled OR = 0.75 (95% CI, 0.44-1.30); p = 0.31). and patients who required sigmoid resection (pooled OR = 3.37 (95% CI, 0.65-17.34); p = 0.15) were not significantly different among patients who received antibiotics and those who did not. Mortality rates were 4 of 1310 (no-antibiotic group) versus 4 of 863 (antibiotic group). LIMITATIONS Only 2 randomized controlled studies were available and there was high heterogeneity in existing data. CONCLUSIONS This meta-analysis of current literature shows that patients with uncomplicated diverticulitis can be monitored off antibiotics.

Abstract
PURPOSE OF REVIEW While few diseases are limited solely to the elderly, diverticular disease is clearly more prevalent with increasing age and therefore the aim of this review is to focus on the clinical implications of diverticular disease in the elderly. RECENT FINDINGS Diverticulitis in the elderly is best managed with an individualized treatment approach including considerations for selective antibiotic usage even in uncomplicated disease. Furthermore, due to the increased prevalence of ischemic colitis in the elderly and the similarities in presentation with diverticular hemorrhage, there needs to be a high index of suspicion and appropriate evaluation for ischemic colitis in patients with hematochezia, particularly if they have abdominal pain. The elderly are a vulnerable population where the index of suspicion for complications of diverticular disease should be high.

Abstract
BACKGROUND Uncomplicated colonic diverticulitis is common. There is no consensus regarding the most appropriate management. Some authors have reported the efficacy and safety of observational management, and others have argued for a more aggressive approach with oral or intravenous antibiotic treatment. OBJECTIVE The purpose of this study was to perform an updated meta-analysis of the different management strategies for uncomplicated diverticulitis with 2 separate meta-analyses. DATA SOURCES MEDLINE, Embase, and Cochrane databases were used. STUDY SELECTION All randomized clinical trials, prospective, and retrospective comparative studies were included. INTERVENTIONS Observational and antibiotics treatment or oral and intravenous antibiotics treatment were included. MAIN OUTCOME MEASURES Successful management (emergency management, recurrence, elective management) was measured. RESULTS After review of 293 identified records, 11 studies fit inclusion criteria: 7 studies compared observational management and antibiotics treatment (2321 patients), and 4 studies compared oral and intravenous antibiotics treatment (355 patients). There was no significant difference between observational management and antibiotics treatment in terms of emergency surgery (0.7% vs 1.4%; p = 0.1) and recurrence (11% vs 12%; p = 0.3). In this part, considering only randomized trials, elective surgery during the follow-up occurred more frequently in the observational group than the antibiotic group (2.5% vs 0.9%; p = 0.04). The second meta-analysis showed that failure and recurrence rates were similar between oral and intravenous antibiotics treatment (6% vs 7% (p = 0.6) and 8% vs 9% (p = 0.8)). LIMITATIONS Inclusion of nonrandomized studies, identification of high risks of bias (selection, performance, and detection bias), and presence of heterogeneity between the studies limited this work. CONCLUSIONS Observational management was not statistically different from antibiotic treatment for the primary outcome of needing to undergo surgery. However, in patients being treated by antibiotics, our studies demonstrated that oral administration was similar to intravenous administration and provided lower costs. Although it may be difficult for physicians to do, there is mounting evidence that not treating uncomplicated colonic diverticulitis with antibiotics is a viable treatment alternative.

Abstract
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.

Abstract
INTRODUCTION Recent studies show that antibiotic therapy is safe and feasible for CT-confirmed uncomplicated acute appendicitis. Spontaneous resolution of acute appendicitis has already been observed over a hundred years ago. In CT-confirmed uncomplicated acute diverticulitis (left-sided appendicitis), studies have shown no benefit from antibiotics compared with symptomatic treatment, but this shift from antibiotics to symptomatic treatment has not yet been widely implemented in clinical practice. Recently, symptomatic treatment of uncomplicated acute appendicitis has been demonstrated in a Korean open-label study. However, a double-blinded placebo-controlled study to illustrate the role of antibiotics and spontaneous resolution of uncomplicated acute appendicitis is still lacking. METHODS AND ANALYSIS The APPAC III (APPendicitis ACuta III) trial is a multicentre, double-blind, placebo-controlled, superiority randomised study comparing antibiotic therapy with placebo in the treatment CT scan-confirmed uncomplicated acute appendicitis aiming to evaluate the role of antibiotics in the resolution of uncomplicated acute appendicitis. Adult patients (18-60 years) with CT scan-confirmed uncomplicated acute appendicitis (the absence of appendicolith, abscess, perforation and tumour) will be enrolled in five Finnish university hospitals.Primary endpoint is success of the randomised treatment, defined as resolution of acute appendicitis resulting in discharge from the hospital without surgical intervention within 10 days after initiating randomised treatment (treatment efficacy). Secondary endpoints include postintervention complications, recurrent symptoms after treatment up to 1 year, late recurrence of acute appendicitis after 1 year, duration of hospital stay, sick leave, treatment costs and quality of life. A decrease of 15 percentage points in success rate is considered clinically important difference. The superiority of antibiotic treatment compared with placebo will be analysed using Fisher's one-sided test and CI will be calculated for proportion difference. ETHICS AND DISSEMINATION This protocol has been approved by the Ethics Committee of Turku University Hospital and the Finnish Medicines Agency (FIMEA). The findings will be disseminated in peer-reviewed academic journals. TRIAL REGISTRATION NUMBER NCT03234296; Pre-results.

Abstract
Diverticular disease is one of the most common conditions in the Western world and one of the most common findings identified at colonoscopy. Recently, there has been a significant paradigm shift in our understanding of diverticular disease and its management. The pathogenesis of diverticular disease is thought to be multifactorial and include both environmental and genetic factors in addition to the historically accepted etiology of dietary fiber deficiency. Symptomatic uncomplicated diverticular disease (SUDD) is currently considered a type of chronic diverticulosis that is perhaps akin to irritable bowel syndrome. Mesalamine, rifaximin and probiotics may achieve symptomatic relief in some patients with SUDD, although their role(s) in preventing complications remain unclear. Antibiotic use for acute diverticulitis and elective prophylactic resection surgery are considered more individualized treatment modalities that take into account the clinical status, comorbidities and lifestyle of the patient. Our understanding of the pathogenesis of diverticular disease continues to evolve and is likely to be diverse and multifactorial. Paradigm shifts in several areas of the pathogenesis and management of diverticular disease are explored in this review.

Abstract
Acute uncomplicated diverticulitis (AUD) is generally felt to be caused by obstruction and inflammation of a colonic diverticulum and occurs in about 4-5% of patients with diverticulosis. The cornerstone of AUD treatment has conventionally been antibiotic therapy, but with a paradigm shift in the underlying pathogenesis of the disease from bacterial infection to more of an inflammatory process, as well as concerns about antibiotic overuse, this dogma has recently been questioned. We will review emerging data that supports more selective antibiotic use in this population, as well as newer guidelines that advocate this position as well. While there are no discrete algorithms to guide us, we will attempt to suggest clinical scenarios where antibiotics may reasonably be withheld.

Abstract
BACKGROUND Diverticulitis is a common complication of diverticular disease of the colon. While complicated diverticulitis often warrants intervention, acute uncomplicated diverticulitis (AUD) is usually managed conservatively. The aim of the present review was to evaluate the efficacy and safety of conservative treatment of AUD without antibiotics compared to standard antibiotic treatment. METHODS A systematic literature review in compliance with PRISMA guidelines was conducted. Electronic databases including PubMed/Medline, Scopus, Embase and Cochrane central register of controlled trials were searched. Studies that assessed efficacy and safety of treatment of AUD without antibiotics were included. Outcome parameters were rates of treatment failure, recurrence of diverticulitis, complications and mortality, readmission to hospital, and need for surgery. RESULTS Nine studies including 2565 patients were included to the review. Of these patients, 65.1% were treated conservatively without antibiotics. Treatment failure was observed in 5.1% of patients not-given-antibiotic treatment versus 3.4% of those given antibiotic treatment. Recurrent diverticulitis occurred in 9.3% of patients in the non-antibiotic group versus 12.1% of patients in the antibiotic group. On meta-analysis of the studies, there were no significant differences between non-antibiotic and antibiotic treatment groups regarding rates of treatment failure (OR = 1.5, p = 0.06), recurrence of diverticulitis (OR = 0.81, p = 0.2), complications (OR = 0.56, p = 0.25), readmission rates (OR = 0.97, p = 0.91), need for surgery (OR = 0.59, p = 0.28), and mortality (OR = 0.64, p = 0.47). The only variable that was significantly associated with treatment failure in the non-antibiotic treatment group was associated comorbidities (standard error (SE) = - 0.07, 95% CI - 0.117 - 0.032; p < 0.001). CONCLUSIONS Treatment of AUD without antibiotics is feasible, safe, and effective. Adding broad-spectrum antibiotics to the treatment regimen did not serve to decrease treatment failure, recurrence, complications, hospital readmissions, and need for surgery significantly compared to non-antibiotic treatment.

Abstract
PURPOSE Outpatient management without antibiotics has been shown to be safe for selected patients diagnosed with acute uncomplicated diverticulitis (AUD). The aim of this study was to evaluate the impact on admissions, complication rates and health-care costs of the policy of outpatient treatment without using antibiotics. METHODS The medical records of all patients diagnosed with AUD in the year before (2011) and after (2014) the implementation of outpatient management without antibiotics in Västmanland County were reviewed. Health-care cost analysis was performed using the Swedish cost-per-patient model. RESULTS In total, 494 episodes of AUD were identified, 254 in 2011 and 240 in 2014. The proportion of patients managed as outpatients was 20% in 2011 compared with 60% in 2014 (p < .001). There were 203 hospital admissions and a total length of stay of 677 days in 2011 compared with 95 admissions and 344 days in 2014 (both p < .001). The total health-care cost was €558,679 in 2011 compared with €370,370 in 2014 (p < .001). Three patients developed complications in 2011 and four in 2014 (p = .469). CONCLUSIONS The new policy of outpatient management without antibiotics in routine health care almost halved the total health-care cost without an increase in the complication rate.

Abstract
BACKGROUND The management of uncomplicated (Modified Hinchey Classification Ia) acute diverticulitis (AD) has become increasingly conservative, with a focus on symptomatic relief and supportive management. Clear criteria for patient selection are required to implement this safely. This retrospective study aimed to identify risk factors for severe clinical course in patients with uncomplicated AD. MATERIALS AND METHODS Patients admitted to General Surgery at two New Zealand tertiary centres over a period of 18 months were included. Univariate and multivariate analyses were carried out in order to identify factors associated with a more severe clinical course. This was defined by three endpoints: need for procedural intervention, admission >7 days and 30-day readmission; these were analysed separately and as a combined outcome. RESULTS Uncomplicated AD was identified in 319 patients. Fifteen patients (5%) required procedural intervention; this was associated with SIRS (OR 3.92). Twenty-two (6.9%) patients were admitted for >7 days; this was associated with patient-reported pain score >8/10 (OR 5.67). Thirty-one patients (9.8%) required readmission within 30 days; this was associated with pain score >8/10 (OR 6.08) and first episode of AD (OR 2.47). Overall, 49 patients had a severe clinical course, and associated factors were regular steroid/immunomodulator use (OR 4.34), pain score >8/10 (OR 5.9) and higher temperature (OR 1.51) and CRP ≥200 (OR 4.1). CONCLUSION SIRS, high pain score and CRP, first episode and regular steroid/immunomodulator use were identified as predictors of worse outcome in uncomplicated AD. These findings have the potential to inform prospective treatment decisions in this patient group.

Abstract
INTRODUCTION Acute diverticulitis (AD) is increasingly seen in Emergency services. The application of a reliable classification is vital for its safe and effective management. OBJECTIVE To determine whether the combined use of the modified Neff radiological classification (mNeff) and clinical criteria (systemic inflammatory response syndrome [SIRS] and comorbidity) can ensure safe management of AD. MATERIAL AND METHODS Prospective descriptive study in a population of patients diagnosed with AD by computerized tomography (CT). The protocol applied consisted in the application of the mNeff classification and clinical criteria of SIRS and comorbidity to guide the choice of outpatient treatment, admission, drainage or surgery. RESULTS The study was carried out from February 2010 to February 2016. A total of 590 episodes of AD were considered: 271 women and 319 men, with a median age of 60 years (range: 25-92 years). mNeff grades were as follows: grade 0 (408 patients 70.6%); 376/408 (92%) were considered for home treatment; of these 376 patients, 254 (67.5%) were discharged and controlled by the Home Hospitalization Unit; 33 returned to the Emergency Room for consultation and 22 were re-admitted; the success rate was 91%. Grade Ia (52, 8.9%): 31/52 (59.6%) were considered for outpatient treatment; of these 31 patients, 11 (35.5%) were discharged; eight patients returned to the Emergency Room for consultation and five were re-admitted. Grade Ib (49, 8.5%): five surgery and two drainage. Grade II (30, 5.2%): ten surgery and four drainage. Grade III (5, 0.9%): one surgery and one drainage. Grade IV (34, 5.9%): ten patients showed good evolution with conservative treatment. Of the 34 grade IV patients, 24 (70.6%) underwent surgery, and three (8.8%) received percutaneous drainage. CONCLUSIONS The mNeff classification is a safe, easy-to-apply classification based on CT findings. Together with clinical data and comorbidity data, it allows better management of AD.

Abstract
BACKGROUND Acute uncomplicated diverticulitis (AUD) is common and antibiotics are the cornerstone of traditional conservative management. This approach lacks clear evidence base and studies have recently suggested that avoidance of antibiotics is a safe and efficacious way to manage AUD. The aim of this systematic review is to determine the safety and efficacy of treating AUD without antibiotics. METHODS A systematic search of Embase, Cochrane library, MEDLINE, Science Citation Index Expanded, and ClinicalTrials. gov was performed. Studies comparing antibiotics versus no antibiotics in the treatment of AUD were included. Meta-analysis was performed using the random effects model with the primary outcome measure being diverticulitis-associated complications. Secondary outcomes were readmission rate, diverticulitis recurrence, mean hospital stay, requirement for surgery and requirement for percutaneous drainage. RESULTS Eight studies were included involving 2469 patients; 1626 in the non-antibiotic group (NAb) and 843 in the antibiotic group (Ab). There was a higher complication rate in the Ab group however this was not significant (1.9% versus 2.6%) with a combined risk ratio (RR) of 0.63 (95% CI, 0.25 to 1.57, p=0.32). There was a shorter mean length of hospital stay in the Nab group (standard mean difference of -1.18 (95% CI, -2.34 to -0.03 p= 0.04). There was no significant difference in readmission, recurrence and surgical intervention rate or requirement for percutaneous drainage. CONCLUSION Treatment of AUD without antibiotics may be feasible with outcomes that are comparable to antibiotic treatment and with potential benefits for patients and the NHS. Large scale randomised multicentre studies are needed. This article is protected by copyright. All rights reserved.

Economic evaluation of antibiotic therapy versus appendicectomy for the treatment of uncomplicated acute appendicitis from the APPAC randomized clinical trial. Br J Surg 2017; 104:1355-1361. [PMID: 28677879 DOI: 10.1002/bjs.10575] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2016] [Revised: 02/14/2017] [Accepted: 03/28/2017] [Indexed: 12/20/2022]
Abstract
BACKGROUND An increasing amount of evidence supports antibiotic therapy for treating uncomplicated acute appendicitis. The objective of this study was to compare the costs of antibiotics alone versus appendicectomy in treating uncomplicated acute appendicitis within the randomized controlled APPAC (APPendicitis ACuta) trial. METHODS The APPAC multicentre, non-inferiority RCT was conducted on patients with CT-confirmed uncomplicated acute appendicitis. Patients were assigned randomly to appendicectomy or antibiotic treatment. All costs were recorded, whether generated by the initial visit and subsequent treatment or possible recurrent appendicitis during the 1-year follow-up. The cost estimates were based on cost levels for the year 2012. RESULTS Some 273 patients were assigned to the appendicectomy group and 257 to antibiotic treatment. Most patients randomized to antibiotic treatment did not require appendicectomy during the 1-year follow-up. In the operative group, overall societal costs (€5989·2, 95 per cent c.i. 5787·3 to 6191·1) were 1·6 times higher (€2244·8, 1940·5 to 2549·1) than those in the antibiotic group (€3744·4, 3514·6 to 3974·2). In both groups, productivity losses represented a slightly higher proportion of overall societal costs than all treatment costs together, with diagnostics and medicines having a minor role. Those in the operative group were prescribed significantly more sick leave than those in the antibiotic group (mean(s.d.) 17·0(8·3) (95 per cent c.i. 16·0 to 18·0) versus 9·2(6·9) (8·3 to 10·0) days respectively; P < 0·001). When the age and sex of the patient as well as the hospital were controlled for simultaneously, the operative treatment generated significantly more costs in all models. CONCLUSION Patients receiving antibiotic therapy for uncomplicated appendicitis incurred lower costs than those who had surgery.

Abstract
Increasing interest in diverticular disease by the scientific community in the last 10-15 years has resulted in an increased number of publications. Among other things, nonevidence-based therapeutic paradigms were tested in randomized, controlled therapy studies. The importance of surgery in the therapy of diverticulitis has diminished in recent years; in particular, it has no role in the treatment of diverticulitis types 1a, 1b, and 2a according to the Classification of Diverticular Disease (CDD) treated successfully by conservative means. Surgery has only a subordinate role in recurrent type 3b diverticulitis according to the CDD. Diverticulitis is therefore increasingly treated using conservative or drug therapy. However, only the classic, established antibiotics are currently available as effective drugs for the treatment of diverticular disease. However, these are also decreasing in significance. Over 90% of patients with type 1a/1b diverticulitis can be safely treated according to current data without the use of antibiotics. It is possible that type 2a diverticulitis will also be successfully treated without antibiotics in the future. Substances such as rifaximin, mesalazine, or probiotics, which were tested above all in patients with chronic recurrent forms (CDD type 3a/3b), have not yet been established.

Adherence to clinical guidelines and the potential economic benefits of admission avoidance for acute uncomplicated diverticulitis. Ir J Med Sci 2017; 187:59-64. [PMID: 28547682 DOI: 10.1007/s11845-017-1632-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2017] [Accepted: 05/12/2017] [Indexed: 12/18/2022]
Abstract
BACKGROUND The treatment paradigm for acute diverticulitis is changing. There is an increasing trend towards managing patients with uncomplicated diverticulitis in the community. AIMS The aim of this study was to analyse how acute diverticulitis is managed in our institution and also to analyse national data pertaining to treatment of acute diverticulitis. METHODS A prospective database of all patients admitted to our institution over a 2-year period (2014-2016) with acute diverticulitis was maintained. Severity of disease, treatment received and average length of stay (LOS) were analysed for all patients. Contemporaneous hospital inpatient enquiry (HIPE) data was interrogated to analyse current management for acute diverticulitis at a national level. RESULTS One hundred twenty-six patients were admitted to our institution with acute diverticulitis during the study period (inpatient stay = €1277/night). Of patients, 59.5% had uncomplicated diverticulitis while 40.5% had complicated disease. The median LOS was 4 (range 1-34) days and 8 (range 2-51) days in the uncomplicated and complicated group, respectively. Based on HIPE data, there were 11,357 patients with uncomplicated diverticulitis and 526 patients with complicated diverticulitis admitted to Irish hospitals in the year 2015. Nationally, the median LOS for those with uncomplicated diverticulitis was 3 (range 1-142) days and for those with complicated diverticulitis the median LOS was 7 (range 1-308) days. Projected total cost for hospital stay nationally for uncomplicated diverticulitis amounted to €43.5 million for the year 2015. CONCLUSIONS At present, uncomplicated diverticulitis in Ireland is not being managed as per evidence-based guidelines. Changing practice could result in significant cost savings for surgical departments.

Abstract
Diverticulitis is a common ailment that is prevalent in the developed world. As such, the management of diverticulitis places a substantial economic burden on healthcare. Research is ongoing to further elucidate both the pathogenesis of the disease, as well as ways to reduce associated expenditures. One of these emerging areas of research calls into question the use of antibiotics during treatment of acute uncomplicated diverticulitis. Current guidelines are largely based on expert opinion, with little evidence supporting the standard practice of antibiotic therapy. In this literature review, we have compiled and analyzed the latest collection of evidence in managing acute uncomplicated diverticulitis. There have been two randomized controlled trials (RCTs) performed that assessed the possibility of treating acute uncomplicated diverticulitis without antibiotics. Both the Antibiotika Vid Okomplicerad Divertikulit (AVOD) study and Daniels, et al. have found that an observational approach to acute uncomplicated diverticulitis is not inferior to antibiotic treatment and does not result in increased complication or recurrence rates. We also reviewed a single-center cohort study, a prospective observational study, and two retrospective case-controlled studies comparing observational management versus antibiotic treatment in patients with acute uncomplicated diverticulitis. We found the results were comparable; there was no difference in complication rates or recurrence in any study. The consensus among the studies reviewed challenges the current practice guidelines issued by the American Gastroenterological Association. However, given the geographical difference in diverticular disease and inherent bias found in these studies, we cannot recommend a modification of the guidelines. Based on this literature review, we feel compelled to suggest, and strongly recommend, further research be conducted in the United States in order to bolster the already significant evidence against antibiotic therapy in acute uncomplicated diverticulitis.

Abstract
AIM The optimal diet for uncomplicated diverticulitis is unclear. Guidelines refrain from recommendation due to lack of objective information. The aim of the study was to determine whether an unrestricted diet during a first acute episode of uncomplicated diverticulitis is safe. METHOD A prospective cohort study was performed of patients diagnosed with diverticulitis for the first time between 2012 and 2014. Requirements for inclusion were radiologically proven modified Hinchey Ia/b diverticulitis, American Society of Anesthesiologists class I-III and the ability to tolerate an unrestricted diet. Exclusion criteria were the use of antibiotics and suspicion of inflammatory bowel disease or malignancy. All included patients were advised to take an unrestricted diet. The primary outcome parameter was morbidity. Secondary outcome measures were the development of recurrence and ongoing symptoms. RESULTS There were 86 patients including 37 (43.0%) men. All patients were confirmed to have taken an unrestricted diet. There were nine adverse events in seven patients. These consisted of readmission for pain (five), recurrent diverticulitis (one) and surgery (three) for ongoing symptoms (two) and Hinchey Stage III (one). Seventeen (19.8%) patients experienced continuing symptoms 6 months after the initial episode and 4 (4.7%) experienced recurrent diverticulitis. CONCLUSION The incidence of complications among patients taking an unrestricted diet during an initial acute uncomplicated episode of diverticulitis was in line with that reported in the literature.

Abstract
PURPOSE The study investigated the capability of clinical findings, temperature, C-reactive protein (CRP), and white blood cell (WBC) count to discern patients with acute colonic diverticulitis from all other patients admitted with acute abdominal pain. METHODS The probability of acute diverticulitis was assessed by the examining doctor, using a scale from 0 (zero probability) to 10 (100 % probability). Receiver operating characteristic (ROC) curves were used to assess the clinical diagnostic accuracy of acute colonic diverticulitis in patients admitted with acute abdominal pain. RESULTS Of 833 patients admitted with acute abdominal pain, 95 had acute colonic diverticulitis. ROC curve analysis gave an area under the ROC curve (AUC) of 0.95 (CI 0.92 to 0.97) for ages <65 years, AUC = 0.86 (CI 0.78 to 0.93) in older patients. Separate analysis showed an AUC = 0.83 (CI 0.80 to 0.86) of CRP alone. White blood cell count and temperature were almost useless to discriminate acute colonic diverticulitis from other types of acute abdominal pain, AUC = 0.59 (CI 0.53 to 0.65) for white blood cell count and AUC = 0.57 (0.50 to 0.63) for temperature, respectively. CONCLUSION This prospective study demonstrates that standard clinical evaluation by non-specialist doctors based on history, physical examination, and initial blood tests on admission provides a high degree of diagnostic precision in patients with acute colonic diverticulitis.

Abstract
PURPOSE First-time acute uncomplicated diverticulitis (AUD) has been considered to have an increased risk of complication, but the level of evidence is low. The aim of the present study was to evaluate the risk of complications in patients with first-time AUD and in patients with a history of diverticulitis. METHODS This paper is a population-based retrospective study at Västmanland's Hospital, Västerås, Sweden, where all patients were identified with a diagnosis of colonic diverticular disease ICD-10 K57.0-9 from January 2010 to December 2014. The records of all patients were surveyed and patients with a computed tomography (CT)-verified AUD were included. Complications defined as CT-verified abscess, perforation, colonic obstruction, fistula, or sepsis within 1 month from the diagnosis of AUD were registered. RESULTS Of 809 patients with AUD, 642 (79%) had first-time AUD and 167 (21%) had a previous history of AUD with no differences in demographic or clinical characteristics. In total, 16 (2%) patients developed a complication within 1 month irrespective of whether they had a previous history of diverticulitis (P = 0.345). In the binary logistic regression analysis, first-time diverticulitis was not associated with increased risk of complications (OR 1.58; CI 0.52-4.81). The rate of antibiotic therapy was about 7-10% during the time period and outpatient management increased from 7% in 2010 to 61% in 2014. CONCLUSIONS The risk for development of complications is low in AUD with no difference between patients with first-time or recurrent diverticulitis. This result strengthens existing evidence on the benign disease course of AUD.

Abstract
AIM This study aimed to evaluate the implementation of nonantibiotic management of acute uncomplicated diverticulitis at a large university hospital in Norway with regard to management failure, disease recurrence and complications. METHOD On 1 January 2013 we implemented a new policy for the management of acute uncomplicated diverticulitis without antibiotics. Antibiotic treatment was only provided in the case of defined criteria. All patients admitted from 1 January 2013 to 30 June 2014 with a CT-verified, left-sided, acute uncomplicated diverticulitis were included in the study and evaluated retrospectively, with 12 months' follow-up. RESULTS Of 244 admissions with acute uncomplicated diverticulitis, 177 (73%) were managed without antibiotics. Among these there were seven (4%) management failures, including five patients in whom a deteriorating clinical picture prompted antibiotic treatment and two readmissions within 1 month due to persisting symptoms. The only complication in this group was one fistula (< 1%). Eight (5%) patients had a recurrence of acute diverticulitis requiring hospital care and two (1%) underwent elective surgery within the first year. Twenty (8%) patients met predefined exemption criteria and received antibiotics from admission, six (30%) of whom developed complications. The recurrence rate in this group was 10% and none had surgery performed. The 47 (20%) policy violators treated with antibiotics from admission had no complications. Their recurrence rate was 11% and one (2%) patient underwent elective surgery. CONCLUSION This study confirms that nonantibiotic management of acute uncomplicated diverticulitis is safe and feasible. Most complications occurred in a small group of high-risk patients treated with antibiotics.

Abstract
BACKGROUND Antibiotics are advised in most guidelines on acute diverticulitis, despite a lack of evidence to support their routine use. This trial compared the effectiveness of a strategy with or without antibiotics for a first episode of uncomplicated acute diverticulitis. METHODS Patients with CT-proven, primary, left-sided, uncomplicated, acute diverticulitis were included at 22 clinical sites in the Netherlands, and assigned randomly to an observational or antibiotic treatment strategy. The primary endpoint was time to recovery during 6 months of follow-up. Main secondary endpoints were readmission rate, complicated, ongoing and recurrent diverticulitis, sigmoid resection and mortality. Intention-to-treat and per-protocol analyses were done. RESULTS A total of 528 patients were included. Median time to recovery was 14 (i.q.r. 6-35) days for the observational and 12 (7-30) days for the antibiotic treatment strategy, with a hazard ratio for recovery of 0·91 (lower limit of 1-sided 95 per cent c.i. 0·78; P = 0·151). No significant differences between the observation and antibiotic treatment groups were found for secondary endpoints: complicated diverticulitis (3·8 versus 2·6 per cent respectively; P = 0·377), ongoing diverticulitis (7·3 versus 4·1 per cent; P = 0·183), recurrent diverticulitis (3·4 versus 3·0 per cent; P = 0·494), sigmoid resection (3·8 versus 2·3 per cent; P = 0·323), readmission (17·6 versus 12·0 per cent; P = 0·148), adverse events (48·5 versus 54·5 per cent; P = 0·221) and mortality (1·1 versus 0·4 per cent; P = 0·432). Hospital stay was significantly shorter in the observation group (2 versus 3 days; P = 0·006). Per-protocol analyses were concordant with the intention-to-treat analyses. CONCLUSION Observational treatment without antibiotics did not prolong recovery and can be considered appropriate in patients with uncomplicated diverticulitis. Registration number: NCT01111253 (http://www.clinicaltrials.gov).

Abstract
Acute diverticulitis occurs in up to 25% of patients with diverticulosis. The majority of cases are mild or uncomplicated and it has become a frequent reason for consultation in the emergency department. On the basis of the National Inpatient Sample database from the USA, 86% of patients admitted with diverticulitis were treated with medical therapy. However, several recent studies have shown that outpatient treatment with antibiotics is safe and effective. The aim of this systematic review is to update the evidence published in the outpatient treatment of uncomplicated acute diverticulitis. We performed a systematic review according to the PRISMA guidelines and searched in MEDLINE and Cochrane databases all English-language articles on the management of acute diverticulitis using the following search terms: 'diverticulitis', 'outpatient', and 'uncomplicated'. Data were extracted independently by two investigators. A total of 11 articles for full review were yielded: one randomized controlled trial, eight prospective cohort studies, and two retrospective cohort studies. Treatment successful rate on an outpatient basis, which means that no further complications were reported, ranged from 91.5 to 100%. Fewer than 8% of patients were readmitted in the hospital. Intolerance to oral intake and lack of family or social support are common exclusion criteria used for this approach, whereas severe comorbidities are not definitive exclusion criteria in all the studies. Ambulatory treatment of uncomplicated acute diverticulitis is safe, effective, and economically efficient when applying an appropriate selection in most reviewed studies.

Clinically Diagnosed Acute Diverticulitis in Outpatients: Misdiagnosis in Patients with Irritable Bowel Syndrome. Dig Dis Sci 2016; 61:578-88.

Abstract
BACKGROUND Physicians often diagnose diverticulitis and prescribe antibiotics in outpatients with abdominal pain and tenderness without other evidence. AIM We investigated the misattribution of irritable bowel syndrome (IBS) symptoms to diverticulitis in outpatients. METHODS In patients diagnosed with diverticulitis and dispensed antibiotics in an integrated healthcare system, we retrospectively compared 15,846 outpatients managed without computed tomography (CT) versus 3750 emergency department/inpatients who had CT. We assessed demographics and past history, including 17 symptom-based somatic and 11 mental disorders and three somatic-mental comorbidity pairs (dyads) coded over 3 years and seven drug classes dispensed over 1 year before diagnosis. RESULTS Univariate analysis showed small intergroup demographic differences. Outpatients had increases in prior diverticulitis, including outpatient-managed episodes, total somatic diagnoses (p < .0001), eight somatic and three mental disorders (p ≤ .015), all three dyads (p ≤ .05), and dispensing of three drug classes (p ≤ .016). IBS had been diagnosed in 2399 (15.1 %) outpatients versus 361 (9.6 %) emergency department/inpatients (p < .0001), the greatest increase in any comorbidity. Emergency department/inpatients had no somatic comorbidity more often but more alcohol dependence, non-dependent drug abuse, and opioid dispensing (p ≤ .05). Regression analysis revealed outpatient care was independently positively associated with younger age, non-Hispanic white race/ethnicity, less Charlson comorbidity, diverticulitis history, IBS, chest pain, dyspepsia, fibromyalgia, low back pain, migraine, acute reaction to stress, and antispasmodic and anxiolytic dispensing and negatively associated with non-dependent drug abuse and opioid dispensing (p ≤ .0226). CONCLUSIONS Multiple types of indirect and concordant evidence suggest misattribution of IBS pain to diverticulitis and unnecessary antibiotic therapy in outpatients.

Abstract
INTRODUCTION Diverticulitis is a common surgical admission that presents with a wide range of symptoms and severity. Overall there has been a shift to conservative management practices, including the consideration of non-antibiotic treatment approaches in select cases. METHODS A national survey of all consultant surgeons evaluating their practices was performed. Reasons for changes in management, use of radiological imaging, role of non-antibiotic treatment approaches and indications for elective surgical management were evaluated. RESULTS Response rate for this survey was 67.7% (n = 67/99). An overwhelming 92.5% stated that computed tomography imaging was routinely used to investigate acute presentations. Interestingly, 22.4% stated they would consider a non-antibiotic treatment approach in uncomplicated diverticulitis. Main reasons for adopting this approach was low inflammatory markers with short duration of symptoms. Co-amoxiclav was the most common antibiotic used for acute diverticulitis, with considerable variability in duration of treatment. Additionally, there was considerable heterogeneity regarding how many recurrences were necessary before surgical management was required. CONCLUSION This review highlights substantial variation in the management of diverticulitis across Ireland. Shifts to non-antibiotic treatment approaches for uncomplicated cases are observed, but less so than in Northern Europe. National guidelines are required to establish uniform treatment protocols including indications for surgical resection.
