Dillen H, Wouters J, Snijders D, Wynants L, Verbakel JY. Factors associated with inappropriateness of antibiotic prescriptions for acutely ill children presenting to ambulatory care in high-income countries: a systematic review and meta-analysis. J Antimicrob Chemother 2024; 79:498-511. [PMID: 38113395 PMCID: PMC10904728 DOI: 10.1093/jac/dkad383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 11/29/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND Acutely ill children are at risk of unwarranted antibiotic prescribing. Data on the appropriateness of antibiotic prescriptions provide insights into potential tailored interventions to promote antibiotic stewardship. OBJECTIVES To examine factors associated with the inappropriateness of antibiotic prescriptions for acutely ill children presenting to ambulatory care in high-income countries. METHODS On 8 September 2022, we systematically searched articles published since 2002 in MEDLINE, Embase, CENTRAL, Web of Science, and grey literature databases. We included studies with acutely ill children presenting to ambulatory care settings in high-income countries reporting on the appropriateness of antibiotic prescriptions. The quality of the studies was evaluated using the Appraisal tool for Cross-Sectional Studies and the Newcastle-Ottawa Scale. Pooled ORs were calculated using random-effects models. Meta-regression, sensitivity and subgroup analysis were also performed. RESULTS We included 40 articles reporting on 30 different factors and their association with inappropriate antibiotic prescribing. 'Appropriateness' covered a wide range of definitions. The following factors were associated with increased inappropriate antibiotic prescribing: acute otitis media diagnosis [pooled OR (95% CI): 2.02 (0.54-7.48)], GP [pooled OR (95% CI) 1.38 (1.00-1.89)] and rural setting [pooled OR (95% CI) 1.47 (1.08-2.02)]. Older patient age and a respiratory tract infection diagnosis have a tendency to be positively associated with inappropriate antibiotic prescribing, but pooling of studies was not possible. CONCLUSIONS Prioritizing acute otitis media, GPs, rural areas, older children and respiratory tract infections within antimicrobial stewardship programmes plays a vital role in promoting responsible antibiotic prescribing. The implementation of a standardized definition of appropriateness is essential to evaluate such programmes.

Abstract
OBJECTIVES This study aimed to identify determinants of inappropriate antibiotic prescription in primary care in developed countries and to construct a framework with the determinants to help understand which actions can best be targeted to counteract development of antimicrobial resistance (AMR). DESIGN A systematic review of peer-reviewed studies reporting determinants of inappropriate antibiotic prescription published through 9 September 2021 in PubMed, Embase, Web of Science and the Cochrane Library was performed. SETTING All studies focusing on primary care in developed countries where general practitioners (GPs) act as gatekeepers for referral to medical specialists and hospital care were included. RESULTS Seventeen studies fulfilled the inclusion criteria and were used for the analysis which identified 45 determinants of inappropriate antibiotic prescription. Important determinants for inappropriate antibiotic prescription were comorbidity, primary care not considered to be responsible for development of AMR and GP perception of patient desire for antibiotics. A framework was constructed with the determinants and provides a broad overview of several domains. The framework can be used to identify several reasons for inappropriate antibiotic prescription in a specific primary care setting and from there, choose the most suitable intervention(s) and assist in implementing them for combatting AMR. CONCLUSIONS The type of infection, comorbidity and the GPs perception of a patient's desire for antibiotics are consistently identified as factors driving inappropriate antibiotic prescription in primary care. A framework with determinants of inappropriate antibiotic prescription may be useful after validation for effective implementation of interventions for decreasing these inappropriate prescriptions.

Abstract
BACKGROUND Antibiotic resistance is mainly driven by (incorrect) use of antibiotics. Most antibiotics are prescribed in family medicine. Therefore, regularly monitoring of antibiotic prescriptions and evaluation of their (non-) prudent use in primary care is warranted. OBJECTIVES The aim of this study was to determine time trends in antibiotic prescriptions by Dutch family physicians (FPs) and to identify determinants of nonprudent antibiotic prescriptions by Dutch FPs. METHODS Retrospective study among 27 Dutch general practices from the Research Network Family Medicine Maastricht, from 2015 to 2019. RESULTS In total 801,767 patient years were analysed. Antibiotic prescriptions mainly increased in patients aged 65+ while prescriptions mainly decreased in patients below 65 years. Nonprudent antibiotic prescriptions decreased from 2015 to 2019 with the highest percentage of decline found in skin infections (66.9% [2015] to 53.9% [2019]). Overall, higher likelihood of nonprudent antibiotic prescriptions was found among men (odds ratio [OR] 4.11, 95% confidence interval [CI]: 3.91-4.33), patients aged 80+ (OR 1.44, 95% CI: 1.03-2.01; reference category ≤17 years), patients with comedication (OR 1.24, 95% CI: 1.17-1.31), and patients in urban general practices (OR 1.47, 95% CI: 1.38-1.56). CONCLUSIONS Antibiotic prescriptions increased over time in the elderly aged categories. Although an overall decrease in nonprudent antibiotic prescriptions was established from 2015 to 2019, percentages of nonprudent prescriptions remained high for skin infections and respiratory tract infections. Additionally, men, elderly aged patients (80+), patients with comedication and patients in urban general practices were more likely to receive nonprudent antibiotic prescriptions. Our results will help FPs to prioritize optimalization of antibiotic prescriptions in family medicine.

Abstract
Objective. To test the predictions of fuzzy-trace theory regarding pediatric clinicians’ decision-making processes and risk perceptions about antibiotics for children with acute otitis media (AOM). Methods. We conducted an online survey experiment administered to a sample of 260 pediatric clinicians. We measured their risk perceptions and prescribing decisions across 3 hypothetical AOM treatment scenarios. Participants were asked to choose among the following options: prescribe antibiotics immediately, watchful waiting (“hedging”), or not prescribing antibiotics. Results. We identified 4 gists based on prior literature: 1) “why not take a risk?” 2) “antibiotics might not help but can hurt,” 3) “antibiotics do not have harmful side effects,” and 4) “antibiotics might have harmful side effects.” All 4 gists predicted risky choice (P < 0.001), and gist endorsements varied significantly between scenarios when antibiotics were indicated, F(2, 255) = 8.53, P < 0.001; F(2, 255) = 5.14, P < .01; and F(2, 255) = 3.56, P < 0.05 for the first 3 factors, respectively. In a logistic regression, more experienced clinicians were less likely to hedge (B = −0.05; P < 0.01). Conclusion. As predicted by fuzzy-trace theory, pediatric clinicians’ prescription decisions are associated with gist representations, which are distinct from verbatim risk estimates. Implications. Antibiotic stewardship programs can benefit by communicating the appropriate gists to clinicians who prescribe antibiotics for pediatric patients.

Abstract
Otitis media (OM) and externa (OE) are painful, recurrent ear conditions. As most otitis publications focus on the bacterial content of childhood ears, there remains a dearth of information regarding the adult ear microbiome including both bacteria and fungi. This study compares the outer ear microbiome of healthy adults to adults affected by OE and OM using both intergenic-transcribed-spacer (ITS) and 16S-rDNA sequencing. The adult ear core microbiome consists of the prokaryote Cutibacterium acnes and the eukaryotic Malassezia arunalokei, M. globosa, and M. restricta. The healthy ear mycobiome is dominated by Malassezia and can be divided into two groups, one dominated by M. arunalokei, the other by M. restricta. Microbiome diversity and biomass varied significantly between healthy and diseased ears, and analyses reveal the presence of a potential mutualistic, protective effect of Malassezia species and C. acnes. The healthy ear core microbiome includes the bacteria Staphylococcus capitis and S. capitis/caprae, while the diseased ear core is composed of known bacterial and fungal pathogens including Aspergillus sp., Candida sp., Pseudomonas aeruginosa, S. aureus, and Corynebacterium jeikeium. The data presented highlight the need for early detection of the cause of otitis to direct more appropriate, efficient treatments. This will improve patient outcomes and promote improved antimicrobial stewardship.

Abstract
Background and Objectives: Primary care physicians frequently prescribe antibiotics for acutely ill children, even though they usually have self-limiting diseases of viral etiology. The aim of this research was to evaluate the routine antibiotic-prescribing habits of primary care in Latvia, in response to children presenting with infections. Materials and Methods: This cross-sectional study included acutely ill children who consulted eighty family physicians (FP) in Latvia, between November 2019 and May 2020. The data regarding patient demographics, diagnoses treated with antibiotics, the choice of antibiotics and the use of diagnostic tests were collected. Results: The study population comprised 2383 patients aged between one month and 17 years, presenting an acute infection episode, who had a face-to-face consultation with an FP. Overall, 29.2% of these patients received an antibiotic prescription. The diagnoses most often treated with antibiotics were otitis (45.8% of all antibiotic prescriptions), acute bronchitis (25.0%) and the common cold (14.8%). The most commonly prescribed antibiotics were amoxicillin (55.9% of prescriptions), amoxicillin/clavulanate (18.1%) and clarithromycin (11.8%). Diagnostic tests were carried out for 59.6% of children presenting with acute infections and preceded 66.4% of antibiotic prescriptions. Conclusion: Our data revealed that a high level of antibiotic prescribing for self-limiting viral infections in children continues to occur. The underuse of narrow-spectrum antibiotics and suboptimal use of diagnostic tests before treatment decision-making were also identified. To achieve a more rational use of antibiotics in primary care for children with a fever, professionals and parents need to be better educated on this subject, and diagnostic tests should be used more extensively, including the implementation of daily point-of-care testing.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Inappropriate antibiotic prescribing is still a major concern that can lead to devastating outcomes including antibiotic resistance. This study aimed to simulate the antibiotic prescribing behaviour by providers for acute respiratory tract infections (ARTIs) and to evaluate the impact of patient expectation, provider's perception of patient's expectation to receive a prescription, and patient's risk for bacterial infection, on the decision to prescribe. METHODS We developed a unique system dynamics (SD) simulation model based on the significant factors that impact the interaction between provider and patient during visits for ARTIs and the decision to prescribe antibiotics. In order to validate the model for different age groups and regions in the United States, we used the sample of 53 000 ARTI patient visits made at outpatient settings between 1993 and 2015, based on the National Ambulatory Medical Care Survey (NAMCS). RESULTS Simulation results reveal that physician diagnosis for prescribing antibiotics is based on physician's experience from their prior prescribing behaviour, their perception of patient's infection risk, and patient's expectation to receive antibiotics. Also, there are some variations depending on patient's age and residential region. The simulation analysis also depicts the decreasing trend in patient's expectation over the past two decades for most age groups and regions. CONCLUSIONS Given the high number of unnecessary prescriptions for ARTI, we found that policies are needed to influence provider's prescribing behaviour through patient's expectation and provider's perception regarding those expectations. Our simulation framework can further be used by policymakers to design and evaluate interventions that may modify the interaction between health providers and patients to optimize antibiotic prescriptions among ARTI patients for different regions and age groups.

Abstract
The microbiota of the upper respiratory tract (URT) protects the host from bacterial pathogenic colonization by competing for adherence to epithelial cells and by immune response regulation that includes the activation of antimicrobial and (anti-)inflammatory components. However, environmental or host factors can modify the microbiota to an unstable community that predisposes the host to infection or inflammation. One of the URT diseases most often encountered in children is otitis media (OM). The role of pathogenic bacteria like Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis in the pathogenesis of OM is well documented. Results from next-generation-sequencing (NGS) studies reveal other bacterial taxa involved in OM, such as Turicella and Alloiococcus Such studies can also identify bacterial taxa that are potentially protective against URT infections, whose beneficial action needs to be substantiated in relevant experimental models and clinical trials. Of note, lactic acid bacteria (LAB) are members of the URT microbiota and associated with a URT ecosystem that is deemed healthy, based on NGS and some experimental and clinical studies. These observations have formed the basis of this review, in which we describe the current knowledge of the molecular and clinical potential of LAB in the URT, which is currently underexplored in microbiome and probiotic research.

Knowledge, Attitudes and Intentions to Prescribe Antibiotics: A Structural Equation Modeling Study of Primary Care Institutions in Hubei, China. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16132385.

Abstract
The aim of this paper is to measure the knowledge and attitudes of primary care physicians toward antibiotic prescriptions and their impacts on antibiotic prescribing. A questionnaire survey was conducted on 625 physicians from 67 primary care facilities in Hubei, China. Structural equation modelling (SEM) was applied to test the theoretical framework derived from the Knowledge, Attitudes, and Practices (KAP) theory. Physicians’ knowledge, five sub-types of attitudes, and three sub-types of behavioral intentions towards antibiotic use were measured. Physicians had limited knowledge about antibiotic prescriptions (average 54.55% correct answers to 11 questions). Although they were generally concerned about antibiotic resistance (mean = 1.28, SD = 0.43), and were reluctant to be submissive to pressures from consumer demands for antibiotics (mean = 1.29, SD = 0.65) and the requirements of defensive practice (mean = 1.11, SD = 0.63), there was a lack of motivation to change prescribing practices (mean = −0.29, SD = 0.70) and strong agreement that other stakeholders should take the responsibility (mean = −1.15, SD = 0.45). The SEM results showed that poor knowledge, unawareness of antibiotic resistance, and limited motivation to change contributed to physicians’ high antibiotics prescriptions (p < 0.001). To curb antibiotic over-prescriptions, improving knowledge itself is not enough. The lack of motivation of physicians to change needs to be addressed through a systematic approach.

Abstract
BACKGROUND Acute otitis media (AOM), or acute middle ear infection, is one of the most frequently occurring childhood diseases, and the most common reason given for prescribing antibiotics in this age group. Guidelines often recommend antibiotics as first-line treatment for severe AOM. However, antibiotics also lead to antibiotic resistance, so preventing episodes of AOM is an urgent priority. OBJECTIVES To assess the effects of probiotics to prevent the occurrence and reduce the severity of acute otitis media in children. SEARCH METHODS We searched CENTRAL, PubMed, Embase, and three other databases (October 2018), two trial registers (October 2018), and conducted a backwards and forwards citation analysis (August 2018). We did not apply any language, publication date, or publication status restrictions. SELECTION CRITERIA Randomised controlled trials (RCTs) of children (aged up to 18 years), comparing probiotics with placebo, usual care, or no probiotic. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the eligibility of trials for inclusion and risk of bias of the included trials, and extracted data using pre-piloted data extraction forms. We analysed dichotomous data as either risk ratio (RR) or odds ratios (OR) and continuous data as mean differences (MD). MAIN RESULTS We included 17 RCTs involving 3488 children, of which 16 RCTs were included in the meta-analyses. Of the 16 RCTs that reported the mean age of children, mean age overall was 2.4 years; in 4 RCTs the mean age of children participating in the trial was less than 1 year old; in 2 RCTs the mean age was between 1 and 2 years old; and in 10 RCTs the mean age was older than 2 years. Probiotic strains evaluated by the trials varied, with 11 of the included RCTs evaluating Lactobacillus-containing probiotics, and six RCTs evaluating Streptococcus-containing probiotics.The proportion of children (i.e. the number of children in each group) experiencing one or more episodes of AOM during the treatment was lower for those taking probiotics (RR 0.77, 95% confidence interval (CI) 0.63 to 0.93; 16 trials; 2961 participants; number needed to treat for an additional beneficial outcome (NNTB) = 10; moderate-certainty evidence).Post hoc subgroup analysis found that among children not prone to otitis media, a lower proportion of children receiving probiotics experienced AOM (RR 0.64, 95% CI 0.49 to 0.84; 11 trials; 2227 participants; NNTB = 9; moderate-certainty evidence). However, among children who were otitis prone, there was no difference between probiotic and comparator groups (RR 0.97, 95% CI 0.85 to 1.11; 5 trials; 734 participants; high-certainty evidence). The test for subgroup differences was significant (P = 0.007).None of the included trials reported on the severity of AOM.The proportion of children experiencing adverse events did not differ between the probiotic and comparator groups (OR 1.54, 95% CI 0.60 to 3.94; 4 trials; 395 participants; low-certainty evidence).Probiotics decreased the proportion of children taking antibiotics for any infection (RR 0.66, 95% CI 0.51 to 0.86; 8 trials; 1768 participants; NNTB = 8; moderate-certainty evidence). Test for subgroup differences (use of antibiotic specifically for AOM, use of antibiotic for infections other than AOM) was not significant.There was no difference in the mean number of school days lost (MD -0.95, 95% CI -2.47 to 0.57; 5 trials; 1280 participants; moderate-certainty evidence). There was no difference between groups in the level of compliance in taking the intervention (RR 1.02, 95% CI 0.99 to 1.05; 5 trials; 990 participants).Probiotics decreased the proportion of children having other infections (RR 0.75, 95% CI 0.65 to 0.87; 11 trials; 3610 participants; NNTB = 12; moderate-certainty evidence). Test for subgroup differences (acute respiratory infections, gastrointestinal infections) was not significant.Probiotic strains trialled and their dose, frequency, and duration of administration varied considerably across studies, which likely contributed to the substantial levels of heterogeneity. Sensitivity testing of funnel plots did not reveal publication bias. AUTHORS' CONCLUSIONS Probiotics may prevent AOM in children not prone to AOM, but the inconsistency of the subgroup analyses suggests caution in interpreting these results. Probiotics decreased the proportion of children taking antibiotics for any infection. The proportion of children experiencing adverse events did not differ between the probiotic and comparator groups. The optimal strain, duration, frequency, and timing of probiotic administration still needs to be established.

Abstract
Objectives To identify and quantify inappropriate systemic antibiotic prescribing in primary care in England, and ultimately to determine the potential for reduction in prescribing of antibiotics. Methods Primary care data from 2013-15 recorded in The Health Improvement Network (THIN) database were used. Potentially inappropriate prescribing events in the database were identified by: (i) comparing prescribing events against treatment guidelines; (ii) comparing actual proportions of consultations resulting in prescription for a set of conditions with the ideal proportions derived from expert opinion; and (iii) identifying high prescribers and their number of prescriptions above an age- and body-system-specific benchmark. Results Applying the most conservative assumptions, 8.8% of all systemic antibiotic prescriptions in English primary care were identified as inappropriate, and in the least conservative scenario 23.1% of prescriptions were inappropriate. All practices had non-zero reduction potentials, ranging from 6.4% to 43.5% in the middle scenario. The four conditions that contributed most to inappropriate prescribing were sore throat (23.0% of identified inappropriate prescriptions), cough (22.2%), sinusitis (7.6%) and acute otitis media (5.7%). One-third of all antibiotic prescriptions lacked an informative diagnostic code. Conclusions This work demonstrates (i) the existence of substantial inappropriate antibiotic prescribing and (ii) poor diagnostic coding in English primary care. All practices (not just the high prescribers) should engage in efforts to improve antimicrobial stewardship. Better diagnostic coding, more precise prescribing guidelines and a deeper understanding of appropriate long-term uses of antibiotics would allow identification of further potential for reductions.

Abstract
OBJECTIVE To investigate areas in need of quality improvement within the diagnostic process and antibiotic treatment of acute respiratory tract infections (RTIs) in Danish general practice by using quality indicators (QIs). DESIGN AND SETTING During a 4-week period in winter 2017, a prospective registration of patients diagnosed with RTIs was conducted in general practice in two regions of Denmark. SUBJECTS Throughout the registration period each patient with symptoms of an RTI was registered. Information about age, symptoms and findings, duration of symptoms, the use and result of clinical tests, allergy towards penicillin, referral to secondary care and the antibiotic given were recorded. MAIN OUTCOME MEASURES Values and acceptable ranges for QIs focusing on the diagnostic process, the decision to prescribe antibiotics and the choice of antibiotics for patients with RTIs. RESULTS Regarding the diagnostic process nearly all QIs for patients diagnosed with acute pharyngotonsillitis and pneumonia fell within the acceptable range. Contrarily, the diagnostic QIs for patients with acute otitis media and acute rhinosinusitis were outside the acceptable range. All indicators designed to measure overuse of antibiotics were outside the acceptable range and nearly all indicators assessing if patients were sufficiently treated fell within the acceptable range. QIs assessing use of the recommended type of antibiotic were only within the acceptable range for patients diagnosed with acute pharyngotonsillitis. CONCLUSION The findings indicate an overuse of antibiotics for RTIs in Danish general practice. Especially management of acute rhinosinusitis and acute bronchitis should be targeted in future quality improvement projects. KEY POINTS To improve antibiotic prescribing in general practice it is important to focus on both the diagnostic process and the prescribing patterns. The findings indicate an overuse of antibiotics for acute respiratory tract infections in Danish general practice. Especially the diagnostic process and antibiotic prescribing patterns for acute rhinosinusitis and acute bronchitis could benefit from future quality improvement interventions.

Abstract
AbstractBackground:Acute mastoiditis remains the commonest intratemporal complication of otitis media in the paediatric population. There has been a lack of consensus regarding the diagnosis and management of acute mastoiditis, resulting in considerable disparity in conservative and surgical management.Objectives:To review the current literature, proposing recommendations for the management of paediatric acute mastoiditis and appraising the treatment outcomes.Method:A systematic review was conducted using PubMed, Web of Science and Cochrane Library databases.Results:Twenty-one studies were included, with a total of 564 patients. Cure rates of medical treatment, conservative surgery and mastoidectomy were 95.9 per cent, 96.3 per cent and 89.1 per cent, respectively.Conclusion:Mastoidectomy may be the most definitive treatment available; however, reviewed data suggest that conservative treatment alone has high efficacy as first-line treatment in uncomplicated cases of acute mastoiditis, and conservative therapy may be an appropriate first-line management when treating acute mastoiditis.

Abstract
BACKGROUND Antibiotic resistance is a public health concern, and is linked to over-prescribing. In self-limiting infections such as acute otitis media (AOM) and acute sinusitis, prescribing remains high despite strong guideline recommendations against the routine use of antibiotics. Early career General Practitioners may find evidence-based prescribing challenging. AIM To establish the prevalence and associations of antibiotic prescribing for AOM and acute sinusitis by Australian vocational trainees in General Practice. METHOD A cross-sectional analysis of data from the Registrar Clinical Encounters in Training (ReCEnT) study. This ongoing, multicentre prospective cohort study documents trainees' consultation-based clinical experiences. Univariate and logistic regression analyses were conducted on data recorded in consultations for AOM or acute sinusitis in nine collection periods during 2010-2014. RESULTS Data from 856 individual trainees (response rate 95.2%) were analysed. AOM was managed in 0.9% of encounters. Antibiotics were prescribed in 78.8% of cases. Prescribing was significantly associated with longer consultation time and first presentation for this problem. There was no significant association with patient age group. Acute sinusitis was managed in 0.9% of encounters. Antibiotics were prescribed in 71.2% of cases. Later-stage trainees and trainees who did not receive their primary medical qualification in Australia were more likely to prescribe an antibiotic for acute sinusitis. CONCLUSION Early career GPs are not prescribing in an evidence-based manner. The complexity of guidelines for AOM and acute sinusitis may be confusing for prescribers, especially early career doctors struggling with inexperience and diagnostic uncertainty. Educational interventions are necessary to bring prescribing rates closer to quality benchmarks.

Abstract
BACKGROUND There is no more challenging a group of pharmaceuticals than antimicrobials. With the antibiotic era came great optimism as countless deaths were prevented from what were previously fatal conditions. Although antimicrobial resistance was quickly identified, the abundance of antibiotics entering the market helped cement attitudes of arrogance as the "battle against pestilence appeared won". Opposite emotions soon followed as many heralded the return of the pre-antibiotic era, suggesting that the "antibiotic pipeline had dried up" and that our existing armament would soon be rendered worthless. DISCUSSION In reality, humans overrate their ecological importance. For millions of years there has been a balance between factors promoting bacterial survival and those disturbing it. The first half century of the "antibiotic era" was characterised by a cavalier attitude disturbing the natural balance; however, recent efforts have been made through several mechanisms to respond and re-strengthen the antimicrobial armament. Such mechanisms include a variety of incentives, educational efforts and negotiations. Today, there are many more "man-made" factors that will determine a new balance or state of ecological harmony. CONCLUSION Antibiotics are not a panacea nor will they ever be inutile. New resistance mechanisms will be identified and new antibiotics will be discovered, but most importantly, we must optimise our application of these extraordinary "biological tools"; therein lays our greatest challenge - creating a society that understands and respects the determinants of the effectiveness of antibiotics.

Abstract
BACKGROUND Acute otitis media (AOM) is the most common bacterial infection among young children in the United States. There are limitations and concerns over its treatment with antibiotics and surgery and so effective preventative measures are attractive. A potential preventative measure is xylitol, a natural sugar substitute that reduces the risk of dental decay. Xylitol can reduce the adherence of Streptococcus pneumoniae (S pneumoniae) and Haemophilus influenzae (H influenzae) to nasopharyngeal cells in vitro. This is an update of a review first published in 2011. OBJECTIVES To assess the efficacy and safety of xylitol to prevent AOM in children aged up to 12 years. SEARCH METHODS We searched CENTRAL (to Issue 12, 2015), MEDLINE (1950 to January 2016), Embase (1974 to January 2016), CINAHL (1981 to January 2016), LILACS (1982 to January 2016), Web of Science (2011 to January 2016) and International Pharmaceutical Abstracts (2000 to January 2016). SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs of children aged 12 years or younger where xylitol supplementation was compared with placebo or no treatment to prevent AOM. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials from search results, assessed and rated study quality and extracted relevant data for inclusion in the review. We contacted trial authors to request missing data. We noted data on any adverse events of xylitol. We extracted data on relevant outcomes and estimated the effect size by calculating risk ratio (RR), risk difference (RD) and associated 95% confidence intervals (CI). MAIN RESULTS We identified five clinical trials that involved 3405 children for inclusion. For this 2016 update, we identified one new trial for inclusion. This trial was systematically reviewed but due to several sources of heterogeneity, was not included in the meta-analysis. The remaining four trials were of adequate methodological quality. In three RCTs that involved a total of 1826 healthy Finnish children attending daycare, there is moderate quality evidence that xylitol (in any form) can reduce the risk of AOM from 30% to around 22% compared with the control group (RR 0.75, 95% CI 0.65 to 0.88). Among the reasons for dropouts, there were no significant differences in abdominal discomfort and rash between the xylitol and the control groups. Xylitol was not effective in reducing AOM among healthy children during a respiratory infection (RR 1.13, 95% CI 0.83 to 1.53; moderate quality evidence) or among otitis-prone healthy children (RR 0.90, 95% CI 0.67 to 1.21; low-quality evidence). AUTHORS' CONCLUSIONS There is moderate quality evidence showing that the prophylactic administration of xylitol among healthy children attending daycare centres can reduce the occurrence of AOM. There is inconclusive evidence with regard to the efficacy of xylitol in preventing AOM among children with respiratory infection, or among otitis-prone children. The meta-analysis was limited because data came from a small number of studies, and most were from the same research group.

Abstract
Antibiotic use is a modifiable driver of antibiotic resistance. In many circumstances, antibiotic use is overly broad or unnecessary. We systematically assessed factors associated with antibiotic prescribing for respiratory tract infections (RTI). Studies were included if they used actual (not self-reported or intended) prescribing data, assessed factors associated with antibiotic prescribing for RTIs, and performed multivariable analysis of associations. We searched Medline, Embase, and International Pharmaceutical Abstracts using keyword and MeSH (medical subject headings) search terms. Two authors reviewed each abstract and independently appraised all included texts. Data on factors affecting antibiotic prescribing were extracted. Our searches retrieved a total of 2,848 abstracts, with 97 included in full-text review and 28 meeting full inclusion criteria. Compared to other factors, diagnosis of acute bronchitis was associated with increased antibiotic prescribing (range of adjusted odds ratios [aOR], 1.56 to 15.9). Features on physical exam, such as fever, purulent sputum, abnormal respiratory exam, and tonsillar exudate, were also associated with higher odds of antibiotic prescribing. Patient desire for an antibiotic was not associated or was modestly associated with prescription (range of aORs, 0.61 to 9.87), in contrast to physician perception of patient desire for antibiotics, which showed a stronger association (range of aORs, 2.11 to 23.3). Physician's perception of patient desire for antibiotics was strongly associated with antibiotic prescribing. Antimicrobial stewardship programs should continue to expand in the outpatient setting and should emphasize clear and direct communication between patients and physicians, as well as signs and symptoms that do and do not predict bacterial etiology of upper respiratory tract infections.

Abstract
Otitis media (OM) in children is clinically important because of its detrimental effects on the development of language and motor coordination and is the most common reason for prescription of antibiotics. A recent bacteriological change in OM pathogens such as emergence of antibiotic resistance and vaccination-mediated pathogenic shift urges us to develop a new non-antibiotic strategy. The middle ear epithelium abundantly secretes a variety of antimicrobial molecules suppressing the viability of the common OM pathogens. Recently, we have demonstrated that the adenoviral vector is able to deliver the β-defensin 2 gene to the middle ear epithelial cells in vitro and in vivo, and adenovirus-mediated overexpression of β-defensin 2 is protective for experimental OM. There are many hurdles limiting successful clinical application of gene delivery to the respiratory epithelium of the tubotympanum; however, intratympanic gene therapy with β-defensin 2 is a promising alternative or adjuvant strategy for the management of OM.

Abstract
BACKGROUND Numerous studies suggest overprescribing of antibiotics for respiratory tract indications (RTIs), without really authenticating inappropriate prescription; the strict criteria of guideline recommendations were not taken into account as information on specific diagnoses, patient characteristics and disease severity was not available. OBJECTIVE The aim of this study is to quantify and qualify inappropriate antibiotic prescribing for RTIs. METHODS This is an observational study of the (antibiotic) management of patients with RTIs, using a detailed registration of RTI consultations by general practitioners (GPs). Consultations of which all necessary information was available were benchmarked to the prescribing guidelines for acute otitis media (AOM), acute sore throat, rhinosinusitis or acute cough. Levels of overprescribing for these indications and factors associated with overprescribing were determined. RESULTS The overall antibiotic prescribing rate was 38%. Of these prescriptions, 46% were not indicated by the guidelines. Relative overprescribing was highest for throat (including tonsillitis) and lowest for ear consultations (including AOM). Absolute overprescribing was highest for lower RTIs (including bronchitis). Overprescribing was highest for patients between 18 and 65 years of age, when GPs felt patients' pressure for an antibiotic treatment, for patients presenting with fever and with complaints longer than 1 week. Underprescribing was observed in <4% of the consultations without a prescription. CONCLUSION Awareness of indications and patient groups provoking antibiotic overprescribing can help in the development of targeted strategies to improve GPs' prescribing routines for RTIs.

Abstract
BACKGROUND Acute otitis media (AOM) is one of the most common diseases in early infancy and childhood. Antibiotic use for AOM varies from 56% in the Netherlands to 95% in the USA, Canada and Australia. This is an update of a Cochrane review first published in The Cochrane Library in Issue 1, 1997 and previously updated in 1999, 2005, 2009 and 2013. OBJECTIVES To assess the effects of antibiotics for children with AOM. SEARCH METHODS We searched CENTRAL (2015, Issue 3), MEDLINE (1966 to April week 3, 2015), OLDMEDLINE (1958 to 1965), EMBASE (January 1990 to April 2015), Current Contents (1966 to April 2015), CINAHL (2008 to April 2015) and LILACS (2008 to April 2015). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing 1) antimicrobial drugs with placebo and 2) immediate antibiotic treatment with expectant observation (including delayed antibiotic prescribing) in children with AOM. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. MAIN RESULTS For the review of antibiotics against placebo, 13 RCTs (3401 children and 3938 AOM episodes) from high-income countries were eligible and had generally low risk of bias. The combined results of the trials revealed that by 24 hours from the start of treatment, 60% of the children had recovered whether or not they had placebo or antibiotics. Pain was not reduced by antibiotics at 24 hours (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.78 to 1.01) but almost a third fewer had residual pain at two to three days (RR 0.70, 95% CI 0.57 to 0.86; number needed to treat for an additional beneficial outcome (NNTB) 20). A quarter fewer had pain at four to seven days (RR 0.76, 95% CI 0.63 to 0.91; NNTB 16) and two-thirds fewer had pain at 10 to 12 days (RR 0.33, 95% CI 0.17 to 0.66; NNTB 7) compared with placebo. Antibiotics did reduce the number of children with abnormal tympanometry findings at two to four weeks (RR 0.82, 95% CI 0.74 to 0.90; NNTB 11), at six to eight weeks (RR 0.88, 95% CI 0.78 to 1.00; NNTB 16) and the number of children with tympanic membrane perforations (RR 0.37, 95% CI 0.18 to 0.76; NNTB 33) and halved contralateral otitis episodes (RR 0.49, 95% CI 0.25 to 0.95; NNTB 11) compared with placebo. However, antibiotics neither reduced the number of children with abnormal tympanometry findings at three months (RR 0.97, 95% CI 0.76 to 1.24) nor the number of children with late AOM recurrences (RR 0.93, 95% CI 0.78 to 1.10) when compared with placebo. Severe complications were rare and did not differ between children treated with antibiotics and those treated with placebo. Adverse events (such as vomiting, diarrhoea or rash) occurred more often in children taking antibiotics (RR 1.38, 95% CI 1.19 to 1.59; number needed to treat for an additional harmful outcome (NNTH) 14). Funnel plots do not suggest publication bias. Individual patient data meta-analysis of a subset of included trials found antibiotics to be most beneficial in children aged less than two years with bilateral AOM, or with both AOM and otorrhoea.For the review of immediate antibiotics against expectant observation, five trials (1149 children) from high-income countries were eligible and had low to moderate risk of bias. Four trials (1007 children) reported outcome data that could be used for this review. From these trials, data from 959 children could be extracted for the meta-analysis of pain at three to seven days. No difference in pain was detectable at three to seven days (RR 0.75, 95% CI 0.50 to 1.12). One trial (247 children) reported data on pain at 11 to 14 days. Immediate antibiotics were not associated with a reduction in the number of children with pain (RR 0.91, 95% CI 0.75 to 1.10) compared with expectant observation. Additionally, no differences in the number of children with abnormal tympanometry findings at four weeks, tympanic membrane perforations and AOM recurrence were observed between groups. No serious complications occurred in either the antibiotic or the expectant observation group. Immediate antibiotics were associated with a substantial increased risk of vomiting, diarrhoea or rash compared with expectant observation (RR 1.71, 95% CI 1.24 to 2.36; NNTH 9).Results from an individual patient data meta-analysis including data from six high-quality trials (1643 children) that were also included as individual trials in our review showed that antibiotics seem to be most beneficial in children younger than two years of age with bilateral AOM (NNTB 4) and in children with both AOM and otorrhoea (NNTB 3). AUTHORS' CONCLUSIONS This review reveals that antibiotics have no early effect on pain, a slight effect on pain in the days following and only a modest effect on the number of children with tympanic perforations, contralateral otitis episodes and abnormal tympanometry findings at two to four weeks and at six to eight weeks compared with placebo in children with AOM. In high-income countries, most cases of AOM spontaneously remit without complications. The benefits of antibiotics must be weighed against the possible harms: for every 14 children treated with antibiotics one child experienced an adverse event (such as vomiting, diarrhoea or rash) that would not have occurred if antibiotics were withheld. Therefore clinical management should emphasise advice about adequate analgesia and the limited role for antibiotics. Antibiotics are most useful in children under two years of age with bilateral AOM, or with both AOM and otorrhoea. For most other children with mild disease in high-income countries, an expectant observational approach seems justified.

Abstract
BACKGROUND Unnecessary prescribing of antibiotics is a major public health concern. General practitioners (GPs) prescribe most antibiotics, often for upper respiratory tract infections (URTIs), and have in general been shown to prescribe antibiotics more often to women. No studies have examined the influence of patient gender on unnecessary antibiotic prescribing. OBJECTIVES To study a possible gender difference in unnecessary antibiotic prescriptions for URTIs in general practice; to assess whether a possible difference is explained by patient demand for antibiotics. METHODS Post-hoc analysis of a cross-sectional study including 15,022 patients with URTI (acute rhinitis, acute otitis media, acute sinusitis, acute pharyngotonsillitis) from Argentina, Denmark, Lithuania, Russia, Spain and Sweden (HAPPY AUDIT Project). The association between gender and unnecessary antibiotic prescriptions, unadjusted and adjusted for treatment demand, was analysed using logistic regression models. RESULTS A total of 25% of patients with URTI received antibiotics; in 45% of the cases, antibiotics were unnecessary. Overall, no gender difference for unnecessary prescribing of antibiotics for URTIs was found. Women with acute otitis media received an unnecessary antibiotic twice as often as men (14.4% versus 7.1%). In Danish patients with acute pharyngotonsillitis, there was a gender difference in unnecessary prescriptions for antibiotics (women 29.1% versus men 48.6%). Some 14% of patients receiving unnecessary antibiotics demonstrated a demand for antibiotics, but no gender difference was found in this group. CONCLUSION This study indicated a high rate of unnecessary antibiotic prescribing for URTIs in general practice, but overall found no gender differences in receiving unnecessary antibiotic prescriptions.

Abstract
Antimicrobials are an extremely valuable resource across the spectrum of modern medicine. Their development has been associated with dramatic reductions in communicable disease mortality and has facilitated technological advances in cancer therapy, transplantation, and surgery. However, this resource is threatened by the dwindling supply of new antimicrobials and the global increase in antimicrobial resistance. There is an urgent need for antimicrobial stewardship (AMS) to protect our remaining antimicrobials for future generations. AMS emphasizes sensible, appropriate antimicrobial management for the benefit of the individual and society as a whole. Within the English National Health Service (NHS), a series of recent policy initiatives have focused on all aspects of AMS, including best practice guidelines for antimicrobial prescribing, enhanced surveillance mechanisms for monitoring antimicrobial use across primary and secondary care, and new prescribing competencies for doctors in training. Here we provide a concise summary to clarify the current position and importance of AMS within the NHS and review the evidence base for AMS recommendations. The evidence supports the impact of AMS strategies on modifying prescribing practice in hospitals, with beneficial effects on both antimicrobial resistance and the incidence of Clostridium difficile, and no evidence of increased sepsis-related mortality. There is also a promising role for novel diagnostic technologies in AMS, both in enhancing microbiological diagnosis and improving the specificity of sepsis diagnosis. More work is needed to establish an evidence base for interventions to improve public and patient education regarding the role of antibiotics in common clinical syndromes, such as respiratory tract infection. Future priorities include establishing novel approaches to antimicrobial management (eg, duration of therapy, combination regimens) to protect against resistance and working with the pharmaceutical industry to promote the development of new antimicrobials.

Abstract
Otitis media (OM), one of the most prevalent diseases in young children, is clinically important owing to its high incidence in children and its potential impact on language development and motor coordination. OM is the most common reason for the prescription of antibiotics (accounting for 25% of prescriptions) due to its extremely high incidence. A recent increase in antibiotic resistance among OM pathogens is emerging as a major public health concern globally, which led us to consider non-antibiotic approaches for the management of OM. In this study, we evaluated gene transfer of an antimicrobial peptide, human β-defensin 2 (DEFB4), using an adenoviral vector (Ad5 with deletions of E1/E3/E4) as a potential therapeutic approach. We demonstrated that the transduction of human β-defensin 2 induces the production of human β-defensin 2 and suppresses non-typeable Haemophilus influenzae (NTHi) adhesion to human middle ear epithelial cells. Moreover, intratympanic inoculation of Ad-DEFB4 was found to attenuate NTHi-induced middle ear effusions without eliciting a significant immune response. Most importantly, intratympanic inoculation of Ad-DEFB4 appeared to significantly augment clearance of NTHi from middle ear cavity. Collectively, our results suggest that intratympanic gene delivery of antimicrobial molecules may serve as an alternative/adjuvant approach for the management of OM.

Abstract
Middle ear infection, otitis media (OM), is clinically important due to the high incidence in children and its impact on the development of language and motor coordination. Previously, we have demonstrated that the human middle ear epithelial cells up-regulate β-defensin 2, a model innate immune molecule, in response to nontypeable Haemophilus influenzae (NTHi), the most common OM pathogen, via TLR2 signaling. NTHi does internalize into the epithelial cells, but its intracellular trafficking and host responses to the internalized NTHi are poorly understood. Here we aimed to determine a role of cytoplasmic pathogen recognition receptors in NTHi-induced β-defensin 2 regulation and NTHi clearance from the middle ear. Notably, we observed that the internalized NTHi is able to exist freely in the cytoplasm of the human epithelial cells after rupturing the surrounding membrane. The human middle ear epithelial cells inhibited NTHi-induced β-defensin 2 production by NOD2 silencing but augmented it by NOD2 over-expression. NTHi-induced β-defensin 2 up-regulation was attenuated by cytochalasin D, an inhibitor of actin polymerization and was enhanced by α-hemolysin, a pore-forming toxin. NOD2 silencing was found to block α-hemolysin-mediated enhancement of NTHi-induced β-defensin 2 up-regulation. NOD2 deficiency appeared to reduce inflammatory reactions in response to intratympanic inoculation of NTHi and inhibit NTHi clearance from the middle ear. Taken together, our findings suggest that a cytoplasmic release of internalized NTHi is involved in the pathogenesis of NTHi infections, and NOD2-mediated β-defensin 2 regulation contributes to the protection against NTHi-induced otitis media.

Abstract
OBJECTIVES Countries generally present their overall use of antibiotics as an indicator of antibiotic prescribing quality. Additional insight is urgently needed for targeted improvement recommendations: first, data on specific clinical indications for which antibiotics are used, and second, on distinguishing whether changes in patient consultation or changes in physician prescribing drive changing antibiotic use for particular indications. The aim of this study was to describe the antibiotic management of infectious diseases in the clinical context, by analysing prescribing by physicians and patient consultation incidences per indication over time. METHODS A database with all contact data for infectious diseases from 45 primary care practices in the Netherlands (2007-10) was used. Consultation incidences, prescribing rates and choice of antibiotic were analysed per International Classification of Primary Care (ICPC) chapter and relevant ICPC codes. RESULTS Antibiotics were prescribed in ∼25% of infectious disease episodes, mainly respiratory infections, urinary infections and ear and skin infections. Overall, this resulted in 300 prescribed courses of antibiotics per 1000 patient-years. Given a stable prescription rate, a 19% increase in the number of consultations explained the increased antibiotic prescribing for urinary tract infections. Given a stable consultation incidence, an 8% reduction in prescribing rate explained the decreased antibiotic prescribing for respiratory tract infections. Macrolides were predominantly prescribed for respiratory disease (∼66%), amoxicillin/clavulanate for respiratory disease (∼42%) and urinary illness (∼25%), and fluoroquinolones for urinary and genital indications. CONCLUSIONS Insight into the reasons for the decreased prescribing for respiratory tract infections and the increased prescribing for urinary tract infections was provided by a detailed analysis of incidences and prescribing rates. For respiratory disease, the second- and third-choice antibiotics were overused. Complete data on infectious disease management, with respect to patient and physician behaviour, are crucial for understanding changes in antibiotic use, and in defining strategies to reduce inappropriate antibiotic use.

Abstract
The study primarily aimed at assessing the appropriateness of antibiotic prescriptions in a section of public health institutions in Lesotho using an assessment tool formulated from principles of antibiotic prescribing. Relevant data on procedures of infection diagnosis and prescribed antibiotics were collected from both inpatient and outpatient case reports for a one-month period in five public hospitals in Lesotho. These were analyzed for the appropriateness of the prescribed antibiotics. Prescription appropriateness assessment was based on conformities of prescribed antibiotics to criteria developed from pertinent principles of antibiotic prescribing. Assessed prescriptions, 307 inpatient and 865 outpatient prescriptions in total, were classified into categories of appropriateness based on extents to which they satisfied conditions defined by combinations of criteria in the assessment tool. Antibiotic prescriptions from inpatient and outpatient departments of study site hospitals were categorized into groups of different degrees of appropriateness. A total of 32.2% inpatient prescriptions and 78.4% outpatient prescriptions assessed were appropriately written for the empiric treatment of infections for which bacterial pathogens were considered absolute or possible etiologies. The use of prescription assessment tools based on principles of antibiotic prescribing is a feasible option of assessing the appropriateness of antibiotic prescriptions, particularly in low-income countries where expert panels cannot be formed.

Abstract
BACKGROUND European disease-specific antibiotic prescribing quality indicators (APQI) were proposed for seven acute indications (bronchitis, upper respiratory infection, cystitis, tonsillitis, sinusitis, otitis media and pneumonia): (a) the percentage of patients prescribed an antibiotic; (b) the percentage of patients receiving the guideline recommended antibiotic; (c) the percentage of patients receiving quinolones. OBJECTIVES To assess the feasibility of calculating values for these 21 APQI using primary care databases; and to assess the quality of antibiotic prescribing in office hours and out-of-hours general practice. METHODS Data was extracted from a morbidity registration network ( http://www.intego.be ) and the out-of-hours service centre in Flanders. Within both databases diagnoses are labelled using the revised second edition of International Classification of Primary Care (ICPC-2-R) and antibiotic prescriptions using Anatomical Therapeutic Chemical (ATC) classification. RESULTS Both databases allow calculation of APQI values and results are similar. Only for cystitis was the percentage of patients prescribed an antibiotic within the proposed acceptable range. For all indications, the percentage of recommended antibiotics was below the proposed acceptable range (80-100%). The percentage of quinolones was within the proposed acceptable range (0-5%) for otitis media, upper respiratory infection and tonsillitis. CONCLUSION Primary care databases can produce APQI values. These values revealed huge opportunities to improve the quality of antibiotic prescribing in office hours and out-of-hours Flemish general practice, especially the prescription of recommended antibiotics.

Abstract
BACKGROUND Although fever in children is often self-limiting, antibiotics are frequently prescribed for febrile illnesses. GPs may consider treating serious infections by prescribing antibiotics. AIM To examine whether alarm signs and/or symptoms for serious infections are related to antibiotic prescription in febrile children in primary care. DESIGN AND SETTING Observational cohort study involving five GP out-of-hours services. METHOD Clinical information was registered and manually recoded. Children (<16 years) with fever having a face-to-face contact with a GP were included. Children who were already using antibiotics or referred to secondary care were excluded. The relation between alarm signs and/or symptoms for serious infections and antibiotic prescription was tested using multivariate logistic regression. RESULTS Of the 8676 included patients (median age 2.4 years), antibiotics were prescribed in 3167 contacts (36.5%). Patient characteristics and alarm signs and/or symptoms positively related to antibiotic prescription were: increasing age (odds ratio [OR] = 1.03; 95% confidence interval [95% CI] = 1.02 to 1.05), temperature measured by GP (OR = 1.72; 95% CI = 1.59 to 1.86), ill appearance (OR = 3.93; 95% CI = 2.85 to 5.42), being inconsolable (OR = 2.27; 95% CI = 1.58 to 3.22), shortness of breath (OR = 2.58; 95% CI = 1.88 to 3.56), duration of fever (OR = 1.31; 95% CI = 1.26 to 1.35). Negative associations were found for neurological signs (OR = 0.45; 95% CI = 0.27 to 0.76), signs of urinary tract infection (OR = 0.63; 95% CI = 0.49 to 0.82), and vomiting and diarrhoea (OR = 0.65; 95% CI = 0.57 to 0.74). These variables explained 19% of the antibiotic prescriptions. CONCLUSION Antibiotics are often prescribed for febrile children. These data suggest that treatment of a supposed serious bacterial infection is a consideration of GPs. However, the relatively low explained variation indicates that other considerations are also involved.

Abstract
BACKGROUND Acute otitis media (AOM) is one of the most common diseases in early infancy and childhood. Antibiotic use for AOM varies from 56% in the Netherlands to 95% in the USA, Canada and Australia. OBJECTIVES To assess the effects of antibiotics for children with AOM. SEARCH METHODS We searched CENTRAL (2012, Issue 10), MEDLINE (1966 to October week 4, 2012), OLDMEDLINE (1958 to 1965), EMBASE (January 1990 to November 2012), Current Contents (1966 to November 2012), CINAHL (2008 to November 2012) and LILACS (2008 to November 2012). SELECTION CRITERIA Randomised controlled trials (RCTs) comparing 1) antimicrobial drugs with placebo and 2) immediate antibiotic treatment with expectant observation (including delayed antibiotic prescribing) in children with AOM. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. MAIN RESULTS For the review of antibiotics against placebo, 12 RCTs (3317 children and 3854 AOM episodes) from high-income countries were eligible. However, one trial did not report patient-relevant outcomes, leaving 11 trials with generally low risk of bias. Pain was not reduced by antibiotics at 24 hours (risk ratio (RR) 0.89; 95% confidence interval (CI) 0.78 to 1.01) but almost a third fewer had residual pain at two to three days (RR 0.70; 95% CI 0.57 to 0.86; number needed to treat for an additional beneficial outcome (NNTB) 20) and fewer had pain at four to seven days (RR 0.79; 95% CI 0.66 to 0.95; NNTB 20). When compared with placebo, antibiotics did not alter the number of abnormal tympanometry findings at either four to six weeks (RR 0.92; 95% CI 0.83 to 1.01) or at three months (RR 0.97; 95% CI 0.76 to 1.24), or the number of AOM recurrences (RR 0.93; 95% CI 0.78 to 1.10). However, antibiotic treatment did lead to a statistically significant reduction of tympanic membrane perforations (RR 0.37; 95% CI 0.18 to 0.76; NNTB 33) and halved contralateral AOM episodes (RR 0.49; 95% CI 0.25 to 0.95; NNTB 11) as compared with placebo. Severe complications were rare and did not differ between children treated with antibiotics and those treated with placebo. Adverse events (such as vomiting, diarrhoea or rash) occurred more often in children taking antibiotics (RR 1.34; 95% CI 1.16 to 1.55; number needed to treat for an additional harmful outcome (NNTH) 14). Funnel plots do not suggest publication bias. Individual patient data meta-analysis of a subset of included trials found antibiotics to be most beneficial in children aged less than two with bilateral AOM, or with both AOM and otorrhoea.For the review of immediate antibiotics against expectant observation, five trials (1149 children) were eligible. Four trials (1007 children) reported outcome data that could be used for this review. From these trials, data from 959 children could be extracted for the meta-analysis on pain at days three to seven. No difference in pain was detectable at three to seven days (RR 0.75; 95% CI 0.50 to 1.12). No serious complications occurred in either the antibiotic group or the expectant observation group. Additionally, no difference in tympanic membrane perforations and AOM recurrence was observed. Immediate antibiotic prescribing was associated with a substantial increased risk of vomiting, diarrhoea or rash as compared with expectant observation (RR 1.71; 95% CI 1.24 to 2.36). AUTHORS' CONCLUSIONS Antibiotic treatment led to a statistically significant reduction of children with AOM experiencing pain at two to seven days compared with placebo but since most children (82%) settle spontaneously, about 20 children must be treated to prevent one suffering from ear pain at two to seven days. Additionally, antibiotic treatment led to a statistically significant reduction of tympanic membrane perforations (NNTB 33) and contralateral AOM episodes (NNTB 11). These benefits must be weighed against the possible harms: for every 14 children treated with antibiotics, one child experienced an adverse event (such as vomiting, diarrhoea or rash) that would not have occurred if antibiotics had been withheld. Antibiotics appear to be most useful in children under two years of age with bilateral AOM, or with both AOM and otorrhoea. For most other children with mild disease, an expectant observational approach seems justified. We have no trials in populations with higher risks of complications.

Abstract
Background Information about antibiotic prescribing practice in primary care is not available for Ireland, unlike other European countries. The study aimed to ascertain the types of antibiotics and the corresponding conditions seen in primary care and whether general practitioners (GPs) felt that an antibiotic was necessary at the time of consultation. This information will be vital to inform future initiatives in prudent antibiotic prescribing in primary care. Methods Participating GPs gathered data on all antibiotics prescribed by them in 100 consecutive patients’ consultations as well as data on the conditions being treated and whether they felt the antibiotic was necessary. Results 171 GPs collected data on 16,899 consultations. An antibiotic was prescribed at 20.16% of these consultations. The majority were prescribed for symptoms or diagnoses associated with the respiratory system; the highest rate of prescribing in these consultations were for patients aged 15–64 years (62.23%). There is a high rate of 2nd and 3rd line agents being used for common ailments such as otitis media and tonsillitis. Amoxicillin, which is recommended as 1st line in most common infections, was twice as likely to be prescribed if the prescription was for deferred used or deemed unnecessary by the GP. Conclusion The study demonstrates that potentially inappropriate prescribing is occurring in the adult population and the high rate of broad-spectrum antimicrobial agents is a major concern. This study also indicates that amoxicillin may be being used for its placebo effect rather than specifically for treatment of a definite bacterial infection.

Abstract
BACKGROUND Antibiotic resistance is one of the principal public health problems worldwide. Currently, inappropriate use of antibiotics is regarded as the principal determinant of resistance, with most of these drugs being prescribed outside a hospital setting. This systematic review sought to identify the factors, attitudes and knowledge linked to misprescription of antibiotics. METHODS A systematic review was conducted using the MEDLINE-PubMed and EMBASE databases. The selection criteria required that papers: (1) be published in English or Spanish; (2) designate their objective as that of addressing attitudes/knowledge or other factors related with the prescribing of antibiotics; and (3) use quality and/or quantity indicators to define misprescription. The following were excluded: any paper that used qualitative methodology and any paper that included descriptive analysis only. RESULTS A total of 46 papers that met the inclusion criteria were included in the review. They were very heterogeneous and displayed major methodological limitations. Doctors' socio-demographic and personal factors did not appear to exert much influence. Complacency (fulfilling what professionals perceived as being patients'/parents' expectations) and, to a lesser extent, fear (fear of possible complications in the patient) were the attitudes associated with misprescription of antibiotics. CONCLUSIONS Before designing interventions aimed at improving the prescription and use of antibiotics, studies are needed to identify precisely which factors influence prescribing.

Abstract
BACKGROUND Acute otitis media (AOM) is the most common bacterial infection among young children in the United States with limitations and concerns over its treatment with antibiotics and surgery. Therefore, effective preventative measures are attractive. A potential preventative measure is xylitol, a natural sugar substitute that reduces the risk for dental decay. Xylitol can reduce the adherence of Streptococcus pneumoniae (S. pneumoniae) and Haemophilus influenzae (H. influenzae) to nasopharyngeal cells in vitro. OBJECTIVES To assess the efficacy and safety of xylitol to prevent AOM in children up to 12 years old. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3) which contains the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (1950 to August Week 1, 2011), EMBASE (1974 to August 2011), CINAHL (1982 to August 2011), Health and Psychosocial Instruments (1985 to August 2011), Healthstar (OVID) (1966 to August 2011) and International Pharmaceutical Abstracts (2000 to August 2011). SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs of children aged 12 years or younger where xylitol supplementation was compared to placebo or no treatment to prevent AOM. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials from search results, assessed and rated study quality and extracted relevant data for inclusion in the review. We contacted trial authors to request missing data. We noted data on any adverse events of xylitol. We extracted data on relevant outcomes and estimated the effect size by calculating risk ratio (RR), risk difference (RD) and associated 95% confidence intervals (CI). MAIN RESULTS We identified four studies of adequate methodological quality that met our eligibility criteria. In three RCTs with a total of 1826 healthy Finnish children attending day care, there was a reduced risk of occurrence of AOM in the xylitol group (in any form) compared to the control group (RR 0.75; 95% CI 0.65 to 0.88). The fourth RCT included 1277 Finnish day care children with a respiratory infection and found no effect of xylitol on reducing the occurrence of AOM (RR 1.13; 95% CI 0.83 to 1.53). Xylitol chewing gum was superior to xylitol syrup in preventing AOM among healthy children (RR 0.59; 95% CI 0.39 to 0.89) but not during respiratory infection (RR 0.68; 95% CI 0.43 to 1.07). There was no difference between xylitol lozenges and xylitol syrups in preventing AOM among healthy children (RR 0.77; 95% CI 0.53 to 1.11) or among children during respiratory infection (RR 0.74; 95% CI 0.47 to 1.14). Similarly, no difference was noted between xylitol chewing gum and xylitol lozenges in preventing AOM among healthy children (RR 0.73; 95% CI 0.47 to 1.13) or among children during respiratory infection (RR 0.92; 95% CI 0.59 to 1.46). Among the reasons for drop-outs, there were no significant differences in abdominal discomfort and rash between the xylitol and the control groups. AUTHORS' CONCLUSIONS There is fair evidence that the prophylactic administration of xylitol among healthy children attending day care centres reduces the occurrence of AOM by 25%. This meta-analysis is limited since the data arise from a small number of studies, mainly from the same research group.

Abstract
Antimicrobial resistance is an important issue in Belgium. For more than a decade, national projects aiming to promote the prudent use of antimicrobials and to decrease antimicrobial resistance in ambulatory, nursing-home and hospital settings have been launched by the Belgian Antibiotic Policy Coordination Committee (BAPCOC), coordinated by the Federal Public Service of Public Health, Food Chain Safety and Environment. In this paper, we describe the implementation of the e-Bug Project in Belgium by the University of Antwerp in collaboration with BAPCOC and supported by the Ministries of Education, and how e-Bug complemented a new national campaign focusing on antibiotic use in children first started on the European Antibiotic Awareness Day in 2008. We also describe the impact of the organization of education in Belgium on the implementation process, as well as plans for the future of e-Bug in our country.

Abstract
OBJECTIVES To assess the variability, appropriateness of antibiotics prescriptions for children under 12 years of age with acute otitis media and to evaluate physicians' adherence to the current clinical practice guideline. METHODS This is a retrospective study. Data source of this study was based on outpatient clinic of Otolaryngology Head-and-Neck surgery department in Taipei Veterans General Hospital, a tertiary referral center, from 2005 to 2008. Children 2 months-12 years old presented in our hospital with the diagnosis of uncomplicated acute otitis media were enrolled. Medical records regarding antibiotics prescriptions were reviewed in details. The adherence of physicians' antibiotics prescription was considered appropriate when totally (three aspects: the prescribed items, dosage and days of prescription) in accord with the current clinical practice guideline for acute otitis media. Factors that may influence the adherence were also analyzed. RESULTS Complete medical record review was conducted in 207 children. Amoxicillin with or without β-lactamase inhibitor was the most used antibiotics (92.7%). The overall adherence of prescription was 8.2%. All of the prescribed antibiotics "items" fulfill the guideline recommendations, while "dosage" was under in 85%, and "days of prescription" was adherent to guideline in 50.7%. The adherence was not correlated to patient's age, gender, nor single or both ear diseases; but is significantly correlated with specialists' years of experience and their service quantity. The senior specialists or those with higher service quantity are less correspond with the guidelines suggestions (OR 6.49, 95% CI: 1.71-24.66, p=0.006). Prescriptions with "non-amoxicillin" are better in concordance with the guidelines, OR of non-adherence is 0.13 (95% CI: 0.003-0.055, p=0.006). CONCLUSIONS The antibiotics prescription for children with acute otitis media varied widely among ENT specialists. The overall adherence was 8.2%. The adherence was not correlated to patient's age, gender, single or both ear infection; but significantly inversely correlated with specialists' years of experience and their service quantity.

Abstract
Many countries now have guidelines on the clinical management of acute otitis media. In almost all, the public health goal of containing acquired resistance in bacteria through reduced antibiotic prescribing is the main aim and basis for recommendations. Despite some partial short-term successes, clinical activity databases and opinion surveys suggest that such restrictive guidelines are not followed closely, so this aim is not achieved. Radical new solutions are needed to tackle irrationalities in healthcare systems which set the short-term physician-patient relationship against long-term public health. Resolving this opposition will require comprehensive policy appraisal and co-ordinated actions at many levels, not just dissemination of evidence and promotion of guidelines. The inappropriate clinical rationales that underpin non-compliance with guidelines can be questioned by evidence, but also need specific developments promoting alternative solutions, within a framework of whole-system thinking. Promising developments would be (a) physician training modules on age-appropriate analgesia and on detection plus referral of rare complications like mastoiditis, and (b) vaccination against the most common and serious bacterial pathogens.

Abstract
The 2007 Recent Advances in Otitis Media Research Conference Panel Report provides an update on otitis media (OM) research published from 2003 to 2007. This report summarizes important trends in disease incidence and prevalence, describes established and newly identified risk factors for acute and chronic OM and OM with effusion, and conveys information on newly discovered genetic factors. In this report, researchers have described declining rates of OM diagnosis, antibiotic prescriptions, offices visits for OM, and middle ear surgery since the licensure and routine use of pneumococcal conjugate vaccine in infants. The panel report also recommends short and long term goals for current and future OM research.

Abstract
BACKGROUND Both treatment guidelines and the amount of antibiotics used for acute otitis media (AOM) vary across western countries. Parental expectations and their awareness of antimicrobial use and resistance, which may also be influenced by the guidelines, are not yet completely known. OBJECTIVE To compare parental experiences and opinions regarding the management of AOM in children with AOM in Finland and The Netherlands. METHODS We sent the questionnaires via public day care in Turku, Finland, and Utrecht, The Netherlands. We asked about family background, child's history of AOM and parental experiences and attitudes about AOM treatment and antimicrobial resistance. RESULTS Of 1151 participants, 83% in Finland and 49% in The Netherlands had had at least one episode of AOM. Antibiotics were used more frequently in Finland than in The Netherlands, 99% versus 78%, respectively. More Finnish parents reported to believe that antibiotics are necessary in the treatment of AOM as compared to Dutch parents. Use of analgesics for AOM was similar (80% in Finland and 86% in The Netherlands). One-third of the parents had discussed resistance with their doctor. According to parental experiences, antimicrobial resistance had caused more problems in Finland than in The Netherlands (20% versus 2%). Finally, 88% of parents in Finland and 65% in The Netherlands were worried that bacteria could become resistant to antibiotics. CONCLUSIONS Treatment practices and parental expectations seem to interact with each other. Therefore, if we aim to change AOM treatment practices, we have to modify both guidelines and parental expectations.

Abstract
BACKGROUND Overuse of broad-spectrum antibiotics is associated with antibiotic resistance. Acute otitis media (AOM) is responsible for a large proportion of antibiotics prescribed for US children. Rates of broad-spectrum antibiotic prescribing for AOM are unknown. METHODS Analysis of the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, 1998 to 2004 (N = 6,878). Setting is office-based physicians, hospital outpatient departments, and emergency departments. Patients are children aged 12 years and younger prescribed antibiotics for acute otitis media. Main outcome measure is percentage of broad-spectrum antibiotics, defined as amoxicillin/clavulanate, macrolides, cephalosporins and quinolones. RESULTS Broad-spectrum prescribing for acute otitis media increased from 34% of visits in 1998 to 45% of visits in 2004 (P < .001 for trend). The trend was primarily attributable to an increase in prescribing of amoxicillin/clavulanate (8% to 15%; P < .001 for trend) and macrolides (9% to 15%; P < .001 for trend). Prescribing remained stable for amoxicillin and cephalosporins while decreasing for narrow-spectrum agents (12% to 3%; P < .001 for trend) over the study period. Independent predictors of broad-spectrum antibiotic prescribing were ear pain, non-white race, public and other insurance (compared to private), hospital outpatient department setting, emergency department setting, and West region (compared to South and Midwest regions), each of which was associated with lower rates of broad-spectrum prescribing. Age and fever were not associated with prescribing choice. CONCLUSION Prescribing of broad-spectrum antibiotics for acute otitis media has steadily increased from 1998 to 2004. Associations with non-clinical factors suggest potential for improvement in prescribing practice.

Abstract
Background Next to other GP characteristics, diagnostic labelling (the proportion of acute respiratory tract (RT) episodes to be labelled as infections) probably contributes to a higher volume of antibiotic prescriptions for acute RT episodes. However, it is unknown whether there is an independent association between diagnostic labelling and the volume of prescribed antibiotics, or whether diagnostic labelling is associated with the number of presented acute RT episodes and consequently with the number of antibiotics prescribed per patient per year. Methods Data were used from the Second Dutch National Survey of General Practice (DNSGP-2) with 163 GPs from 85 Dutch practices, serving a population of 359,625 patients. Data over a 12 month period were analysed by means of multiple linear regression analysis. Main outcome measure was the volume of antibiotic prescriptions for acute RT episodes per 1,000 patients. Results The incidence was 236.9 acute RT episodes/1,000 patients. GPs labelled about 70% of acute RT episodes as infections, and antibiotics were prescribed in 41% of all acute RT episodes. A higher incidence of acute RT episodes (beta 0.67), a stronger inclination to label episodes as infections (beta 0.24), a stronger endorsement of the need of antibiotics in case of white spots in the throat (beta 0.11) and being male (beta 0.11) were independent determinants of the prescribed volume of antibiotics for acute RT episodes, whereas diagnostic labelling was not correlated with the incidence of acute RT episodes. Conclusion Diagnostic labelling is a relevant factor in GPs' antibiotic prescribing independent from the incidence of acute RT episodes. Therefore, quality assurance programs and postgraduate courses should emphasise to use evidence based prognostic criteria (e.g. chronic respiratory co-morbidity and old age) as an indication to prescribe antibiotics in stead of single inflammation signs or diagnostic labels.

Abstract
Changes in nasopharyngeal bacterial flora in adults with acute upper respiratory tract infection on administration of antimicrobial agents were investigated, and how these changes contrasted with those in children. Many patients with acute sinusitis due to allergies, and patients with malignancy and diabetes mellitus were included in the investigation. The detection rates of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, the major bacteria of acute otitis media (AOM), were 22%, 10%, and 7% respectively, which were significantly lower than those for children. Gram stain examination of nasopharyngeal swab samples showed a significant relation between leukocyte infiltration and the detection amount of S. pneumoniae (P = 0.0086). A significant relation (P = 0.0134) was also observed when H. influenzae was simultaneously detected. No significant change in the three major AOM bacteria present in nasopharyngeal bacterial flora after administration of antimicrobial agents was observed. However, all S. pneumoniae and H. influenzae detected after antimicrobial agent administration had the beta-lactam-resistance gene. It was observed that a significant improvement in leukocyte infiltration occurred 6 to 10 days after antimicrobial agent administration. In contrast, a significant improvement in children was observed at 2 to 5 days. In the adult subjects, this improvement was probably due to spontaneous remission rather than the effect of the antimicrobial agents. Although investigation of the long-term administration of antimicrobial agents was also conducted, its benefits for the patients were not elucidated.

Abstract
OBJECTIVE To investigate the quality of antibiotic prescribing in primary care using quality indicators and the relatedness of these indicators. To determine the influence of general practice and practice population characteristics on the indicator scores. METHODS Data on performance were collected during the Second National Survey of General Practice over 1 year between May 2000 and April 2002 in The Netherlands. The study was carried out in 104 computerised general practices, comprising 195 general practitioners and about 400,000 patients. From a preliminary set of quality indicators on antibiotic prescribing (n = 15), eight were selected covering various medical conditions. Indicator scores were derived. A factor analysis was performed to examine the relatedness of these indicators. Composite scores were calculated for the indicators loading on the same factor. The influence of general practice and practice population characteristics on the quality of antibiotic prescribing was investigated. RESULTS Considerable variation was found between indicator scores (32.8-94.2%) and between practices. The factor analysis discovered two interpretable factors-namely, "first choice prescribing" and "restrictive prescribing". The composite scores were 64% and 68%, respectively. No significant correlation was found between the two composite scores. Practice and population characteristics explained only a small proportion of the variance between practices. CONCLUSIONS Although different quality indicators on antibiotic prescribing are grouped together over several medical conditions, there is large variation between those indicators. General practices performing well on first choice prescribing do not automatically perform well on restrictive prescribing. There is room for improvement on both aspects of prescribing. The variation between practices is clearly present and should be further investigated.

Abstract
Acute otitis media (AOM) is an important infectious disease among children throughout the world. The management of AOM is complicated by difficulties in diagnosis, spontaneous resolution, altered microbiology after pneumococcal conjugate vaccine use, and expanding antimicrobial resistance. The recent introduction of the heptavalent pneumococcal vaccine has resulted in a decrease in AOM due to penicillin-nonsusceptible strains of Streptococcus pneumoniae (PNSP) and an increase in infection due to beta-lactamase-positive nontypeable Haemophilus influenzae. The results of in vitro susceptibility testing in the context of broad surveillance programs provide useful information regarding the potency and spectrum of the oral beta-lactam antibacterial agents used in the treatment of AOM. The application of pharmacokinetic/pharmacodynamic breakpoints provides an effective means of projecting the potential clinical efficacy of the available agents. In view of what appears to be an increase prominence of beta-lactamase-positive Gram-negative AOM pathogens and a decrease in PNSP, it appears that empiric therapy for AOM should now include an agent with activity against beta-lactamase-positive H. influenzae and S. pneumoniae.
