Abstract
BACKGROUND Most US children with acute otitis media [AOM] receive prompt antibiotic treatment, though guidelines encourage watchful waiting. Previous systematic reviews of antibiotics versus watchful waiting have focused on symptom resolution and RCTs, limiting the assessment of serious, rare complications. We sought to evaluate these complications by including observational studies. METHODS RCTs and observational studies that compared antibiotics to placebo or watchful waiting for pediatric clinician diagnosed AOM were identified [PubMed/MEDLINE, Embase, Cochrane Database of Systematic Reviews, Central Register of Controlled Trials, and Web of Science] and reviewed for meta-analysis. Two reviewers independently extracted study characteristics, patient characteristics, and outcomes. We assessed publication bias, study bias with ROBINS-1 and RoB-2 and used random-effects models to assess treatment effects. RESULTS 24 studies were included. Antibiotics decreased the risk of acute mastoiditis [incidence 0.02%, RR 0.48, 95% CI 0.40-0.59; NNT 5,368]. This protective effect may be underestimated because of misclassification of non-suppurative conditions as AOM. Intracranial complications remained too rare to assess. Antibiotics markedly increased the risk of adverse effects [incidence 10.5%, RR 1.49, 1.27-1.73; NNH 23]. Studies used non-specific criteria for acute mastoiditis, potentially underestimating treatment effects. CONCLUSIONS Prompt antibiotic therapy reduces the risk for some AOM complications. The NNT to prevent serious, rare complications is high, while the NNH is relatively low. Large-scale population-based observational studies using real-world datasets with validated measures of severe complications are needed to improve understanding of risk factors for serious AOM complications, facilitate more selective antibiotic therapy, and optimize individual outcomes and public health.

Abstract
BACKGROUND Acute otitis media (AOM) is one of the most common diseases in childhood for which antibiotics are commonly prescribed; a systematic review reported a pooled prevalence of 85.6% in high-income countries. This is an update of a Cochrane Review first published in the Cochrane Library in 1997 and updated in 1999, 2005, 2009, 2013 and 2015. OBJECTIVES To assess the effects of antibiotics for children with AOM. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Current Contents, CINAHL, LILACS and two trial registers. The date of the search was 14 February 2023. SELECTION CRITERIA We included randomised controlled trials 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 screened trials for inclusion and extracted data using the standard methodological procedures recommended by Cochrane. Our primary outcomes were: 1) pain at various time points (24 hours, two to three days, four to seven days, 10 to 14 days), and 2) adverse effects likely to be related to the use of antibiotics. Secondary outcomes were: 1) abnormal tympanometry findings, 2) tympanic membrane perforation, 3) contralateral otitis (in unilateral cases), 4) AOM recurrences, 5) serious complications related to AOM and 6) long-term effects (including the number of parent-reported AOM symptom episodes, antibiotic prescriptions and health care utilisation as assessed at least one year after randomisation). We used the GRADE approach to rate the overall certainty of evidence for each outcome of interest. MAIN RESULTS Antibiotics versus placebo We included 13 trials (3401 children and 3938 AOM episodes) from high-income countries, which we assessed at generally low risk of bias. Antibiotics do not reduce pain at 24 hours (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.78 to 1.01; 5 trials, 1394 children; high-certainty evidence), or at four to seven days (RR 0.76, 95% CI 0.50 to 1.14; 7 trials, 1264 children), but result in almost a third fewer children having pain at two to three days (RR 0.71, 95% CI 0.58 to 0.88; number needed to treat for an additional beneficial outcome (NNTB) 20; 7 trials, 2320 children; high-certainty evidence), and likely result in two-thirds fewer having pain at 10 to 12 days (RR 0.33, 95% CI 0.17 to 0.66; NNTB 7; 1 trial, 278 children; moderate-certainty evidence). Antibiotics increase the risk of adverse events such as vomiting, diarrhoea or rash (RR 1.38, 95% CI 1.16 to 1.63; number needed to treat for an additional harmful outcome (NNTH) 14; 8 trials, 2107 children; high-certainty evidence). Antibiotics reduce the risk of children having abnormal tympanometry findings at two to four weeks (RR 0.83, 95% CI 0.72 to 0.96; NNTB 11; 7 trials, 2138 children), slightly reduce the risk of experiencing tympanic membrane perforations (RR 0.43, 95% CI 0.21 to 0.89; NNTB 33; 5 trials, 1075 children) and halve the risk of contralateral otitis episodes (RR 0.49, 95% CI 0.25 to 0.95; NNTB 11; 4 trials, 906 children). However, antibiotics do not reduce the risk of abnormal tympanometry findings at six to eight weeks (RR 0.89, 95% CI 0.70 to 1.13; 3 trials, 953 children) and at three months (RR 0.94, 95% CI 0.66 to 1.34; 3 trials, 809 children) or late AOM recurrences (RR 0.94, 95% CI 0.79 to 1.11; 6 trials, 2200 children). Severe complications were rare, and the evidence suggests that serious complications do not differ between children treated with either antibiotics or placebo. Immediate antibiotics versus expectant observation We included six trials (1556 children) from high-income countries. The evidence suggests that immediate antibiotics may result in a reduction of pain at two to three days (RR 0.53, 95% CI 0.35 to 0.79; NNTB 8; 1 trial, 396 children; low-certainty evidence), but probably do not reduce the risk of pain at three to seven days (RR 0.75, 95% CI 0.50 to 1.12; 4 trials, 959 children; moderate-certainty evidence), and may not reduce the risk of pain at 11 to 14 days (RR 0.91, 95% CI 0.75 to 1.10; 1 trial, 247 children; low-certainty evidence). Immediate antibiotics increase the risk of vomiting, diarrhoea or rash (RR 1.87, 95% CI 1.39 to 2.51; NNTH 10; 3 trials, 946 children; high-certainty evidence). Immediate antibiotics probably do not reduce the proportion of children with abnormal tympanometry findings at four weeks and evidence suggests that immediate antibiotics may not reduce the risk of tympanic membrane perforation and AOM recurrences. No serious complications occurred in either group. AUTHORS' CONCLUSIONS This review reveals that antibiotics probably have no effect on pain at 24 hours, 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 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. For most children with mild disease in high-income countries, an expectant observational approach seems justified. Therefore, clinical management should emphasise advice about adequate analgesia and the limited role for antibiotics.

[PMID: 30262365 DOI: 10.1016/j.ijporl.2018.08.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2018] [Revised: 08/12/2018] [Accepted: 08/13/2018] [Indexed: 01/22/2023]
Abstract
OBJECTIVES The high incidence of Acute Otitis Media (AOM) along with low antibiotic efficacy in the treatment of AOM is particularly favorable for the emergence of antimicrobial resistance. The promotion of more conservative antibiotic prescription habits has become an important focus of governments and academic societies. Little is known about the awareness and use of AOM practice guidelines by physicians in the Middle East. Our aim is to characterize AOM management in Lebanon by using an anonymous survey instrument to uncover potential disparities in treatment trends and evaluate differences in clinical guideline adherence patterns. METHODS A total of 75 practicing physicians were anonymously surveyed in Beirut, Saida, Nabatieh, Bekaa and Tripoli, Lebanon. The survey tool used was previously used in Amman, Jordan by our colleagues at the University of Michigan. The survey we used assessed awareness of and adherence to practice guidelines by prompting responses to hypothetical AOM cases. Differences in performance between various physician groups were noted. RESULTS Overall, physician participants answered 67% of the survey questions correctly. Trainees did better overall in terms of AOM management (62% correct responses as compared to 48% in attending physicians, p = 0.0175). Trainees also performed better in terms of their ability to manage cases of potential AOM in two-year old children and their ability to choose the appropriate medications (79% correct response rate compared to 71% in attending physicians, p = 0.0278). Participants who reported guideline adherence most or all of the time had a 67% correct response rate in regards to their ability to diagnosis AOM, compared to a 57% correct response rate in those who reported adhering sometimes or rarely to the guidelines (p = 0.0489). In the cases requiring antibiotic treatment for body temp of over 39C with/without otalgia, only 47-57% of participants identified the appropriate antibiotic regimen. CONCLUSION There are areas of potential improvement in adherence to clinical guidelines in the management, diagnosis, and treatment of AOM by Lebanese physicians. Conducting interventions among physicians to improve awareness of clinical guidelines and current treatment recommendations in Lebanon will likely improve adherence to guidelines, enhance clinical outcomes, and may help advance the fight against antimicrobial resistance.

Abstract
OBJECTIVES Otitis media with effusion (OME) is an important clinical entity because of its high prevalence, difficulties in diagnosis, complications and diversities in management. Herein, we aimed to evaluate current physician approaches on OME and determine clinical adherence to current guidelines. METHODS AND MATERIALS A total of 370 physicians [Group 1: pediatricians (n = 256, 69.2%), Group 2: otorhinolarynologists (n = 114, 30.8%)] completed a survey instrument addressing demographic data and clinical practice parameters on OME in children. We also compared clinical approaches of Group 1 and Group 2. In addition, multiple logistic regression analysis was performed to evaluate factors which may effect correct approaches. RESULTS The mean period of clinical experience was 9.30 ± 8.35 [median 6 (1-40)] years. A total of 311 (84%) respondents reported satisfactory level of self-confidence as regards of clinical approaches to OME. Reduced mobility of the tympanic membrane and preference of pneumatic otoscopy was signified by 107 (28.9%) and 64 (17.3%) respondents, respectively. Fifty-six (15.1%) physicians identified "watchful waiting" for 3 months for children who are not at risk while 314 (84.9%) reported preference of medications, with antibiotics the most preferred prescription (n = 223, 63%). Comparison of Group 1 and Group 2 indicated similar results except better, yet insufficient, characterization of physical examination findings of OME by Group 2 (p < 0.001, for each parameter). Group 2 preferred tympanometry more in uncertain cases (p < 0.001) and handled chronic cases better (p < 0.001). Multiple logistic regression analysis revealed lower signification of reduced mobility of the tympanic membrane for respondents who denoted depending on personal experience ([OR] = 3.077 [95% CI 1.042-9.09]) or following clinical guidelines ([OR] = 3.365 [95% CI 1.38-8.20]) rather than combining them both. Rate of antibiotic avoidance was lowest in physicians with a period of clinical experience<5 years ([OR] = 2.14 [95% CI 1.32-3.48]). CONCLUSIONS Despite notifying high self-confidence and adherence to current guidelines on OME, both pediatricians and otorhinolaryngologists lacked to exhibit proper approaches. Further research is warranted to evaluate the causes of poor adherence to current guidelines and bring suggestions for the maintenance of consistent and correct clinical approaches to OME.

The use of practice guidelines in the management of pediatric cases of Acute Otitis Media in Amman, Jordan. Int J Pediatr Otorhinolaryngol 2017; 96:39-46.

Abstract
OBJECTIVES The widespread emergence of antimicrobial resistance has led many healthcare institutions to adopt more conservative antibiotic prescription practice guidelines for the treatment of acute otitis media (AOM). Little is known about the awareness and use of such guidelines by physicians in Jordan. Our aim was to pilot an anonymous survey instrument that would assess AOM treatment trends as well as awareness of and adherence to practice guidelines in Amman. By qualitatively assessing the management of AOM we could illuminate possible disparities in treatment trends, evaluate variability in practice guideline adherence, and help focus efforts of future educational programs that pertain to pediatric AOM management. METHODS A total of 71 practicing physicians were anonymously surveyed in Amman, Jordan. The survey assessed awareness of and adherence to practice guidelines by prompting responses to hypothetical AOM cases. Differences in performance between various physician groups were noted. RESULTS In total, participants answered 61.2% of the questions correctly. It was found that trainees would prescribe more appropriate antibiotics relative to attending physicians (p = 0.008). It was found that medical physicians followed guidelines more appropriately relative to ENT surgeons (64.2% of questions answered correctly vs. 58.1% of questions answered correctly; p = 0.015) and that physicians who report adhering to guidelines all/most of the time followed guidelines more appropriately relative to those who report adhering only sometimes or never (64.0% of questions answered correctly vs. 58.0% of questions answered correctly; p = 0.011). Also, cases that dealt with children were the most difficult for participants to diagnose as compared with cases that dealt with adults. CONCLUSION We conducted the first known qualitative analysis of otitis media practices in Amman and found numerous shortcomings in AOM guideline familiarity. Awareness of practice guidelines can lead to more appropriate AOM management, but there is variability between groups in guideline familiarity and utilization. Interventions that promote more conservative antibiotic prescriptions could be targeted towards groups that prescribe antibiotics less appropriately relative to their colleagues e.g. attending physicians and ENT surgeons. Interventions could also target physicians who manage pediatric AOM cases as participants had the most difficulty in properly diagnosing cases that involved children and infants.

Abstract
Objectives To evaluate the presence of viruses and bacteria in middle ear and adenoids of patients with and without otitis media with effusion (OME). Methods Adenoid samples and middle ear washes (MEW) were obtained from children with OME associated with adenoid hypertrophy undergoing adenoidectomy and tympanostomy, and compared to those obtained from patients undergoing cochlear implant surgery, as a control group. Specific DNA or RNA of 9 respiratory viruses (rhinovirus, influenza virus, picornavirus, syncytial respiratory virus, metapneumovirus, coronavirus, enterovirus, adenovirus and bocavirus) and 5 bacteria (S. pneumoniae, H. influenzae, M. catarrhalis, P. aeruginosa and S. aureus) were extracted and quantified by real-time PCR. Results 37 OME and 14 cochlear implant children were included in the study. At the adenoid, virus and bacteria were similarly detected in both OME and control patients. At the middle ear washes, however, a higher prevalence of bacteria was observed in patients with OME (p = 0.01). S. pneumoniae (p = 0.01) and M. catarrhalis (p = 0.022) were the bacteria responsible for this difference. Although total virus detection was not statistically different from controls at the middle ear washes (p = 0.065), adenovirus was detected in higher proportions in adenoid samples of OME patients than controls (p = 0.019). Conclusions Despite both OME and control patients presented similar rates of viruses and bacteria at the adenoid, children with OME presented higher prevalence of S. pneumonia, M. catarrhalis in middle ear and adenovirus in adenoids when compared to controls. These findings could suggest that these pathogens could contribute to the fluid persistence in the middle ear.

Abstract
OBJECTIVE This update of a 2004 guideline codeveloped by the American Academy of Otolaryngology-Head and Neck Surgery Foundation, the American Academy of Pediatrics, and the American Academy of Family Physicians, provides evidence-based recommendations to manage otitis media with effusion (OME), defined as the presence of fluid in the middle ear without signs or symptoms of acute ear infection. Changes from the prior guideline include consumer advocates added to the update group, evidence from 4 new clinical practice guidelines, 20 new systematic reviews, and 49 randomized control trials, enhanced emphasis on patient education and shared decision making, a new algorithm to clarify action statement relationships, and new and expanded recommendations for the diagnosis and management of OME. PURPOSE The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing OME and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to improve diagnostic accuracy, identify children who are most susceptible to developmental sequelae from OME, and educate clinicians and patients regarding the favorable natural history of most OME and the clinical benefits for medical therapy (eg, steroids, antihistamines, decongestants). Additional goals relate to OME surveillance, hearing and language evaluation, and management of OME detected by newborn screening. The target patient for the guideline is a child aged 2 months through 12 years with OME, with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for all clinicians who are likely to diagnose and manage children with OME, and it applies to any setting in which OME would be identified, monitored, or managed. This guideline, however, does not apply to patients <2 months or >12 years old. ACTION STATEMENTS The update group made strong recommendations that clinicians (1) should document the presence of middle ear effusion with pneumatic otoscopy when diagnosing OME in a child; (2) should perform pneumatic otoscopy to assess for OME in a child with otalgia, hearing loss, or both; (3) should obtain tympanometry in children with suspected OME for whom the diagnosis is uncertain after performing (or attempting) pneumatic otoscopy; (4) should manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known) or 3 months from the date of diagnosis (if onset is unknown); (5) should recommend against using intranasal or systemic steroids for treating OME; (6) should recommend against using systemic antibiotics for treating OME; and (7) should recommend against using antihistamines, decongestants, or both for treating OME.The update group made recommendations that clinicians (1) should document in the medical record counseling of parents of infants with OME who fail a newborn screening regarding the importance of follow-up to ensure that hearing is normal when OME resolves and to exclude an underlying sensorineural hearing loss; (2) should determine if a child with OME is at increased risk for speech, language, or learning problems from middle ear effusion because of baseline sensory, physical, cognitive, or behavioral factors; (3) should evaluate at-risk children for OME at the time of diagnosis of an at-risk condition and at 12 to 18 months of age (if diagnosed as being at risk prior to this time); (4) should not routinely screen children for OME who are not at risk and do not have symptoms that may be attributable to OME, such as hearing difficulties, balance (vestibular) problems, poor school performance, behavioral problems, or ear discomfort; (5) should educate children with OME and their families regarding the natural history of OME, need for follow-up, and the possible sequelae; (6) should obtain an age-appropriate hearing test if OME persists for 3 months or longer OR for OME of any duration in an at-risk child; (7) should counsel families of children with bilateral OME and documented hearing loss about the potential impact on speech and language development; (8) should reevaluate, at 3- to 6-month intervals, children with chronic OME until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected; (9) should recommend tympanostomy tubes when surgery is performed for OME in a child <4 years old; adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); (10) should recommend tympanostomy tubes, adenoidectomy, or both when surgery is performed for OME in a child ≥4 years old; and (11) should document resolution of OME, improved hearing, or improved quality of life when managing a child with OME.

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
OBJECTIVE To establish the extent to which systematic reviews and meta-analyses of individual participant data (IPD) are being used to inform the recommendations included in published clinical guidelines. DESIGN Descriptive study. SETTING Database maintained by the Cochrane IPD Meta-analysis Methods Group, supplemented by records of published IPD meta-analyses held in a separate database. POPULATION A test sample of systematic reviews of randomised controlled trials that included a meta-analysis of IPD, and a separate sample of clinical guidelines, matched to the IPD meta-analyses according to medical condition, interventions, populations, and dates of publication. DATA EXTRACTION Descriptive information on each guideline was extracted along with evidence showing use or critical appraisal, or both, of the IPD meta-analysis within the guideline; recommendations based directly on its findings and the use of other systematic reviews in the guideline. RESULTS Based on 33 IPD meta-analyses and 177 eligible, matched clinical guidelines there was evidence that IPD meta-analyses were being under-utilised. Only 66 guidelines (37%) cited a matched IPD meta-analysis. Around a third of these (n=22, 34%) had critically appraised the IPD meta-analysis. Recommendations based directly on the matched IPD meta-analyses were identified for only 18 of the 66 guidelines (27%). For the guidelines that did not cite a matched IPD meta-analysis (n=111, 63%), search dates had preceded the publication of the IPD meta-analysis in 23 cases (21%); however, for the remainder, there was no obvious reasons why the IPD meta-analysis had not been cited. CONCLUSIONS Our results indicate that systematic reviews and meta-analyses based on IPD are being under-utilised. Guideline developers should routinely seek good quality and up to date IPD meta-analyses to inform guidelines. Increased use of IPD meta-analyses could lead to improved guidelines ensuring that routine patient care is based on the most reliable evidence available.

Abstract
BACKGROUND AND OBJECTIVES Otitis media (OM) is one of the most common reasons for antibiotic treatment in children. Controversies regarding antibiotic treatment for OM have accumulated in the past decade, and there seem to be more dilemmas than certainties. The objectives of this article are to provide the state-of-the art review on achievements in treatment of all different stages of OM, including acute otitis media (AOM), otitis media with effusion (OME), and chronic suppurative otitis media, and to outline the future research areas. DATA SOURCES PubMed, Ovid Medline, the Cochrane Database, and Clinical Evidence (BMJ Publishing). REVIEW METHODS All types of articles related to OM treatment published in English between January 2007 and June 2011 were identified. A total of 286 articles related to OM treatment were reviewed by the panel members; 114 relevant quality articles were identified and summarized. RESULTS New evidence emerged on beneficial results of antibiotic treatment, compared with observation of AOM in young children who were diagnosed based on stringent criteria. In OME, the main results were related to a nonsignificant benefit of adenoidectomy versus tympanostomy tube placement alone in the treatment of chronic OME in younger children. Other modalities of OM treatment were studied and described herein. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Significant progress has been made in advancing the knowledge on the treatment of OM. Areas of potential future research have been identified and outlined.

Abstract
This evidence-based clinical practice guideline is a revision of the 2004 acute otitis media (AOM) guideline from the American Academy of Pediatrics (AAP) and American Academy of Family Physicians. It provides recommendations to primary care clinicians for the management of children from 6 months through 12 years of age with uncomplicated AOM. In 2009, the AAP convened a committee composed of primary care physicians and experts in the fields of pediatrics, family practice, otolaryngology, epidemiology, infectious disease, emergency medicine, and guideline methodology. The subcommittee partnered with the Agency for Healthcare Research and Quality and the Southern California Evidence-Based Practice Center to develop a comprehensive review of the new literature related to AOM since the initial evidence report of 2000. The resulting evidence report and other sources of data were used to formulate the practice guideline recommendations. The focus of this practice guideline is the appropriate diagnosis and initial treatment of a child presenting with AOM. The guideline provides a specific, stringent definition of AOM. It addresses pain management, initial observation versus antibiotic treatment, appropriate choices of antibiotic agents, and preventive measures. It also addresses recurrent AOM, which was not included in the 2004 guideline. Decisions were made on the basis of a systematic grading of the quality of evidence and benefit-harm relationships. The practice guideline underwent comprehensive peer review before formal approval by the AAP. This clinical practice guideline is not intended as a sole source of guidance in the management of children with AOM. Rather, it is intended to assist primary care clinicians by providing a framework for clinical decision-making. It is not intended to replace clinical judgment or establish a protocol for all children with this condition. These recommendations may not provide the only appropriate approach to the management of this problem.

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.

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 Prognostic factors are associated with the risk of a subsequent outcome in people with a given disease or health condition. Meta-analysis using individual participant data (IPD), where the raw data are synthesised from multiple studies, has been championed as the gold-standard for synthesising prognostic factor studies. We assessed the feasibility and conduct of this approach. Methods A systematic review to identify published IPD meta-analyses of prognostic factors studies, followed by detailed assessment of a random sample of 20 articles published from 2006. Six of these 20 articles were from the IMPACT (International Mission for Prognosis and Analysis of Clinical Trials in traumatic brain injury) collaboration, for which additional information was also used from simultaneously published companion papers. Results Forty-eight published IPD meta-analyses of prognostic factors were identified up to March 2009. Only three were published before 2000 but thereafter a median of four articles exist per year, with traumatic brain injury the most active research field. Availability of IPD offered many advantages, such as checking modelling assumptions; analysing variables on their continuous scale with the possibility of assessing for non-linear relationships; and obtaining results adjusted for other variables. However, researchers also faced many challenges, such as large cost and time required to obtain and clean IPD; unavailable IPD for some studies; different sets of prognostic factors in each study; and variability in study methods of measurement. The IMPACT initiative is a leading example, and had generally strong design, methodological and statistical standards. Elsewhere, standards are not always as high and improvements in the conduct of IPD meta-analyses of prognostic factor studies are often needed; in particular, continuous variables are often categorised without reason; publication bias and availability bias are rarely examined; and important methodological details and summary results are often inadequately reported. Conclusions IPD meta-analyses of prognostic factors are achievable and offer many advantages, as displayed most expertly by the IMPACT initiative. However such projects face numerous logistical and methodological obstacles, and their conduct and reporting can often be substantially improved.

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.

Acute otitis media: From diagnosis to prevention. Summary of the Italian guideline. Int J Pediatr Otorhinolaryngol 2010; 74:1209-16. [PMID: 20843561 DOI: 10.1016/j.ijporl.2010.08.016] [Citation(s) in RCA: 71] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2010] [Revised: 08/17/2010] [Accepted: 08/18/2010] [Indexed: 11/21/2022]
Abstract
Acute otitis media (AOM) is the most common disease occurring in infants and children and has major medical, social and economic effects. If we consider the Italian pediatric population and the incidence rates in different age ranges it can be calculated that almost one million cases of AOM are diagnosed in Italy every year. Various attempts have been made internationally to clarify the most appropriate ways in which AOM should be managed. In Italy, this has been done at local or regional level but there have so far been no national initiatives. The objective of this guideline is to provide recommendations to pediatricians, general practitioners and otolaryngologists involved in the clinical management of acute otitis media in healthy children aged 2 months to 12 years. After a systematic review and grading of evidences from the literature, the document was drafted by a multidisciplinary panel with identified key clinical questions related to diagnosis, treatment of the acute episode, management of complications and prevention.

Abstract
BACKGROUND Acute otitis media (AOM) is a common illness during childhood, for which antibiotics are frequently prescribed. OBJECTIVES To determine the effectiveness of a short course of antibiotics (less than seven days) in comparison to a long course of antibiotics (seven days or greater) for the treatment of AOM in children. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009, issue 4) which contains the Acute Respiratory Infections Group's Specialised Register, MEDLINE, EMBASE, MEDLINE In-Process & Other Non-Indexed Citations, CINAHL, BIOSIS Previews, OCLC Papers First and Proceedings First, Proquest Dissertations and Theses (inception to November 2009); International Pharmaceutical Abstracts, the NLM Gateway, ClinicalTrials.gov and Current Controlled Trials (inception to August 2008). SELECTION CRITERIA Trials were included if they met the following criteria: participants aged one month to 18 years; clinical diagnosis of ear infection; no previous antimicrobial therapy; and randomisation to treatment with less than seven days versus seven days or more of antibiotics. DATA COLLECTION AND ANALYSIS The primary outcome of treatment failure was defined as the absence of clinical resolution, relapse or recurrence of AOM during one month following initiation of therapy. Treatment outcomes were extracted from individual studies and combined in the form of a summary odds ratio (OR). A summary OR of 1.0 indicates that the treatment failure rate following less than seven days of antibiotic treatment was similar to the failure rate following seven days or more of treatment. MAIN RESULTS This update included 49 trials containing 12,045 participants. Risk of treatment failure was higher with short courses of antibiotics (OR 1.34, 95% CI 1.15 to 1.55) at one month after initiation of therapy (21% failure with short-course treatment and 18% with long-course; absolute difference of 3% between groups). There were no differences found when examining treatment with ceftriaxone for less than seven days (30% failure in those receiving ceftriaxone and 27% in short-acting antibiotics administered for seven days or more) or azithromycin for less than seven days (18% failure in both those receiving azithromycin and short-acting antibiotics administered for seven days or more) with respect to risk of treatment failure at one month or less. Significant reductions in gastrointestinal adverse events were observed for treatment with short-acting antibiotics and azithromycin. AUTHORS' CONCLUSIONS Clinicians need to evaluate whether the minimal short-term benefit from longer treatment of antibiotics is worth exposing children to a longer course of antibiotics.

Abstract
Otitis media typically presents as either acute otitis media (AOM), with symptoms including fever, otalgia, otorrhoea or irritability and short duration; or as otitis media with effusion (OME), which is often asymptomatic and characterised by accumulation of fluid in the middle ear. Diagnostic certainty of otitis media is challenging, given the young age of patients and variability of symptoms. Otitis media predominantly occurs as coincident to viral upper respiratory tract infections and/or bacterial infections. Common viruses that cause upper respiratory tract infection are frequently associated with AOM and new‐onset OME. These include respiratory syncytial virus, rhinovirus, adenovirus, parainfluenza and coronavirus. Predominant bacteria that cause otitis media are Streptococcus pneumoniae, Moraxella catarrhalis, and non‐typeable Haemophilus influenzae. Antibiotic therapy does not significantly benefit most patients with AOM, but long‐term prophylactic antibiotic therapy can reduce the risk of otitis media recurrence among children at high risk. In Australia, 84% of AOM is treated with antibiotic therapy, which contributes to development of antibiotic resistance. Vaccine development is a key future direction for reducing the world burden of otitis media, but requires polymicrobial formulation and ongoing monitoring and modification to ensure sustained reduction in disease burden.

Abstract
BACKGROUND Acute otitis media is one of the most common diseases in early infancy and childhood. Antibiotic use for acute otitis media varies from 31% in the Netherlands to 98% in the USA and Australia. OBJECTIVES The objective of this review was to assess the effects of antibiotics for children with acute otitis media. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE, Index Medicus (pre 1965), Current Contents and reference lists of articles from 1958 to January 2000. The search was updated in 2003. SELECTION CRITERIA Randomised trials comparing antimicrobial drugs with placebo in children with acute otitis media. DATA COLLECTION AND ANALYSIS Three reviewers independently assessed trial quality and extracted data. MAIN RESULTS Ten trials were eligible based on design, only eight of the trials, with a total of 2,287 children, included patient-relevant outcomes. The methodological quality of the included trials was generally high. All trials were from developed countries. The trials showed no reduction in pain at 24 hours, but a 30% relative reduction (95% confidence interval 19% to 40%) in pain at two to seven days. Since approximately 80% of patients will have settled spontaneously in this time, this means an absolute reduction of 7% or that about 15 children must be treated with antibiotics to prevent one child having some pain after two days. There was no effect of antibiotics on hearing problems of acute otitis media, as measured by subsequent tympanometry. However, audiometry was done in only two studies and incompletely reported. Nor did antibiotics influence other complications or recurrence. There were few serious complications seen in these trials: only one case of mastoiditis occurred in a penicillin treated group. REVIEWER'S CONCLUSIONS Antibiotics provide a small benefit for acute otitis media in children. As most cases will resolve spontaneously, this benefit must be weighed against the possible adverse reactions. Antibiotic treatment may play an important role in reducing the risk of mastoiditis in populations where it is more common.
