The impact of recurrent acute otitis media on the quality of life of children and their caregivers

Gut microbiota composition in recurrent acute otitis media: a cross-sectional observational study

Recurrent acute otitis media (rAOM) poses a significant challenge in children aged 1 to 6 years, characterized by frequent and treatment-resistant ear infections. While existing studies predominantly focus on alterations in the nasopharyngeal microbiome associated with rAOM, our research explores the understudied association with the gut microbiome. In this cross-sectional observational prospective study, we enrolled 35 children aged 1 to 6 years during the 2021/2022 cold season. The test group comprised children with rAOM (n = 16), and the control group consisted of generally healthy children (n = 19). Samples (stool and nasopharyngeal swabs) were collected in late spring to ensure an antibiotic-free period. Detailed metadata was gathered through a questionnaire examining factors potentially influencing microbiota. Microbiota composition was assessed through amplicon sequencing of the V3-V4 region of the 16S rRNA gene. Our findings revealed limited alterations in gut microbiota composition among children with rAOM compared to healthy controls. Six bacterial taxa (Veillonella, Lachnospiraceae, Ruminococcaceae, Lachnospiraceae, Bacteroides and Blautia) were differentially represented with weak statistical significance. However, several bacterial taxa displayed correlations with multiple consecutive infections, with Turicibacter showing the most significant association. Additionally, day care centre attendance emerged as a potent gut microbiota modifier, independent of rAOM. Although our study identified limited differences in gut microbiota composition between children with rAOM and healthy controls, the observed correlations between the number of infections and specific bacterial taxa suggest a potential link between rAOM and the gut microbiota, warranting further investigation.

The Impact of Early-Life Recurrent Otitis Media in Children on the Psychological Well-Being of Caregivers

AIM

Children with early-life recurrent otitis media (OM) will often endure pain, sleep disturbances, and other developmental setbacks that impact the surrounding family system. The aim of this study was to investigate the psychological well-being and family functioning of caregivers of children with early-life recurrent OM (rOM).

METHODS

Data from a longitudinal pregnancy cohort were used to categorize children into two groups: those with a history of recurrent OM (rOM group) and those without a history of rOM (reference group) by the age of 3 years. The psychological well-being of caregivers and the family functioning status were assessed using the Affect Balance Scale and the General Functioning Scale of the McMaster Family Assessment Device (FAD-GF), respectively, at the three-, five-, and eight-year follow-up appointments. Multiple linear regression models were used to analyze the data and were adjusted for potential confounding variables.

RESULTS

There were significant associations between having a child with an early history of rOM and the Affect Balance Scale of caregivers for the negative affects subscale at the three- (p < 0.001) and five- (p = 0.018) year follow-ups, and the Affect Balance subscale at the three-year (p = 0.007) and the five-year follow-ups (p = 0.047). There were no significant associations measured during the 8-year follow-up period for the FAD-GF.

CONCLUSION

The findings of this study further highlight the impact of caring for a child with rOM in early childhood on caregivers' psychological well-being in the first five years of a child's life. The impact, however, did not appear to influence the longer-term functioning of the family as a whole.

Recurrent acute otitis media: a survey of current management in England

OBJECTIVE

Recurrent acute otitis media is common in children. The preferred treatment measures for recurrent acute otitis media have a mixed evidence base. This study sought to assess baseline practice across ENT departments in England.

METHODS

A national telephone survey of healthcare staff was conducted. Every ENT centre in England was contacted. A telephone script was used to ask about antibiotic and grommet use and duration in recurrent acute otitis media cases.

RESULTS

Ninety-six centres (74 per cent) provided complete information. Recurrent acute otitis media treatment across England by ENT departments varied. The antibiotic first- and second-line prophylaxis offered varies, with trimethoprim used in 33 centres and 29 centres not offering any antibiotics. The timing or choice about when to use grommets also varies, but 87 centres (91 per cent) offer grommet surgery at one stage.

CONCLUSION

The treatments received by children in England for recurrent acute otitis media vary by centre; collaborative research in this area is advised.

Encouraging rational antibiotic prescribing behaviour in primary care - prescribing practice among children aged 0-4 years 2016-2018: an observational study

OBJECTIVE

To study antibiotic prescriptions among 0- to 4-year-old children before and after implementing a quality project on prudent prescribing of antibiotics in primary healthcare in the capital region of Iceland.

DESIGN

An observational, descriptive, retrospective study using quantitative methodology.

SETTING

Primary healthcare in the Reykjavik area with a total population of approximately 220,000.

SUBJECTS

A total of 6420 children 0-4 years of age presenting at the primary healthcare centres in the metropolitan area over three years from 2016 to 2018.

MAIN OUTCOME MEASURES

Reduction of antibiotic prescriptions and change in antibiotic profile. Data on antibiotic prescriptions for children 0-4 years of age was obtained from the medical records. Out-of-hours prescriptions were not included in the database.

RESULTS

The number of prescriptions during the study period ranged from 263.6 to 289.6 prescriptions/1000 inhabitants/year. A reduction of 9% in the total number of prescriptions between 2017-2018 was observed. More than half of all prescriptions were for otitis media, followed by pneumonia and skin infections. Amoxicillin accounted for over half of all prescriptions, increasing between 2016 and 2018 by 51.3%. During this period, the prescribing of co-amoxiclav and macrolides decreased by 52.3% and 40.7%, respectively. These changes were significant in all cases, p < 0.0001.

CONCLUSION

The results show an overall decrease in antibiotic prescribing concurrent with a change in the choice of antibiotics prescribed and in line with the recommendations presented in the prescribing guidelines implemented by the Primary Healthcare of the Capital Area, and consistent with the project's goals.Key pointsA substantial proportion of antibiotic prescribing can be considered inappropriate and the antibiotic prescription rate is highest in Iceland of the Nordic countries.After implementing guidance on the treatment of common infections together with feedback on antibiotic prescribing, a decrease in the total number of prescriptions accompanied by a shift in the antibiotic profile was observed.

Association of in utero antibiotic exposure on childhood ear infection trajectories: Results from a national birth cohort study

AIM

Most prescribed medicines during pregnancy are antibiotics, with unknown effects on a fetus and on the infant's acquired microbiome. This study investigates associations between in utero antibiotic exposure and ear infection trajectories over the first decade of life, hypothesising effects on early or persistent, rather than later-developing, ear infections.

METHODS

Design and participants: The Longitudinal Study of Australian Children birth cohort recruited a nationally-representative sample of 5107 infants in 2004.

MEASURES

Mothers reported antibiotic use in pregnancy when a child was 3-21 months old (wave 1), and ongoing problems with ear infection every 2 years spanning ages 0-1 to 10-11 years (waves 1-6).

ANALYSIS

Latent class models identified ear infection trajectories, and univariable and multivariable multinomial logistic regression determined odds of adverse trajectories by antibiotic exposure.

RESULTS

A total of 4500 (88.1% of original sample) children contributed (mean baseline age 0.7 years; 51.3% boys); 10.4% of mothers reported antibiotic use in pregnancy. Four probability trajectories for ear infection emerged: 'consistently low' (86.2%), 'moderate to low' (5.6%), 'low to moderate' (6.7%) and 'consistently high' (1.4%). Antibiotic use in pregnancy was associated with children following 'consistently high' (adjusted odds ratio 2.04, 95% confidence interval 1.08-3.88, P = 0.03) and 'moderate to low' (adjusted odds ratio 1.78, 95% confidence interval 1.25-2.53, P = 0.001) trajectories.

CONCLUSIONS

Antibiotic use in pregnancy is associated with an increased risk of persistent and early childhood ear infections. This highlights the wisdom of cautious antibiotic use during pregnancy, and the need for the study of potential mechanisms underlying these associations.

Parent information needs and experience regarding acute otitis media in children: A systematic review

BACKGROUND

Acute otitis media (AOM)-inflammation of the middle ear-is the most common pediatric condition, affecting up to 75 % of children at some time before age 5 years. Despite the high incidence of AOM in children, it presents diverse challenges to parents who do not have accurate information on AOM and its management.

OBJECTIVE

To respond to this paucity of information we sought to synthesize the literature to provide a comprehensive understanding of parental information needs and experiences relating to AOMmanagement. This systematic review is an important first step in developing parent-informed knowledge translation tools for AOM to bridge the knowledge-practice gap.

PATIENT INVOLVEMENT

None.

METHOD

Four electronic databases were searched and articles were screened according to pre- established inclusion criteria. Articles were included in the review if they (1) examined parental information needs and experiences with respect to AOM; (2) were written in English; and (3) were published from January 2000 onward.

RESULTS

Out of 1121 articles retrieved, 21 articles met the inclusion criteria. The findings from this review revealed that parents' knowledge about AOM is generally limited. Further, parents were often poorly informed about what AOM was, which resulted in uncertainty about how to help their child with AOM.

DISCUSSION

Our review findings illustrate that parents of children with AOM have pervasive unmet information needs and information deficits negatively impact AOM management, child and family well-being.

PRACTICAL VALUE

Parental experiences and information needs identified through this review were used to develop innovative, evidence-based knowledge translation tools for parents of children with AOM.

Parental perceptions and management strategies for otitis media in Greenland

INTRODUCTION

Otitis media (OM) in Greenland is a substantial problem and the country prevalence is among the highest in the world. However, little is known about how Greenlandic Inuit parents perceive and manage everyday life with children suffering from OM. We hypothesize that having a child with OM has consequences for the families that go beyond the advice and treatment offered in primary health care.

METHODS

We conducted a qualitative study based on semi-structured interviews and focus groups with parents to children suffering from OM. The interviews took place in three different Greenlandic regions; the capital Nuuk and two smaller towns in West and East Greenland. Access to specialized health care differs among the regions, creating an underlying difference on the limitations of referral and thereby level of care. We conducted the data analysis using Systematic Text Condensation.

RESULTS

In total, 27 parents participated in the study. Although most parents perceived OM as a result of genetic or environmental dispositions, individual perceptions and cultural beliefs of causal associations between behavior and OM co-existed with the general understanding of medical explanation models. This created a sense of guilt among the parents. Some parents felt in control of managing the disease of the child and used medically well-established strategies. Others felt frustrated and considered contact to the health clinics as futile, thereby managing the disease by 'waiting it out'. Emerging themes were shame and stigma related to the symptoms of OM, which led to social isolation as a consequence for several of the families.

CONCLUSION

Our results indicate that Greenlandic Inuit families are impacted by OM in a complex and severe manner. Guilt, shame and social isolation were predominant themes influencing the everyday life of the affected families. Perceptions and management strategies go beyond the scope of the medical explanation models which poses a potential challenge for the parents' experiences with the present treatment offer. The results underline the need to develop a broader approach to prevention and treatment for OM - both at the clinical level as well as part of public health promotion at the community level.

Preventing unnecessary tympanostomy tube placement in children

OBJECTIVE

In 2013 the American Academy of Otolaryngology published tympanostomy tube guidelines for children; Action Statement 6 recommends against tube placement without middle ear effusion (MEE) at time of assessment. To date, little research has directly evaluated this recommendation in reducing the need for ear tubes. We evaluated the effectiveness of this recommendation and potential risk factors that influence the success of watchful waiting.

METHODS

Retrospective chart review collecting demographics, daycare status, smoking exposure, and time of year of visit. Children aged 6 months to 12 years without MEE on presentation, but with 3 or more episodes of acute otitis media (AOM) in 6 months or 4 or more episodes in 12 months, were assigned to watchful waiting (WW) treatment. These patients were followed every 4 months or returned sooner with additional infections. Any continued AOM, or MEE on follow up leading to tube placement, defined WW failure.

RESULTS

123 patients met criteria, with 81 still in WW to date (66% success rate). 42 children failed WW and received tympanostomy tubes (34% failure rate). There were no statistically significant associations between age, race, gender, smoking exposure, daycare, or month of presentation between children who failed WW compared to children receiving tubes.

CONCLUSIONS

Tympanostomy tube guidelines mitigate unnecessary tube placement in a majority of children with recurrent AOM without MEE. To our knowledge, this is the first study supporting the 2013 recommendations, with a 66% success rate. Additionally, no significant associations between modifying risk factors in those who failed watchful waiting were identified.

Grommets (ventilation tubes) for recurrent acute otitis media in children

BACKGROUND

Acute otitis media (AOM) is one of the most common childhood illnesses. While many children experience sporadic AOM episodes, an important group suffer from recurrent AOM (rAOM), defined as three or more episodes in six months, or four or more in one year. In this subset of children AOM poses a true burden through frequent episodes of ear pain, general illness, sleepless nights and time lost from nursery or school. Grommets, also called ventilation or tympanostomy tubes, can be offered for rAOM.

OBJECTIVES

To assess the benefits and harms of bilateral grommet insertion with or without concurrent adenoidectomy in children with rAOM.

SEARCH METHODS

The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; CENTRAL; MEDLINE; EMBASE; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 4 December 2017.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing bilateral grommet insertion with or without concurrent adenoidectomy and no ear surgery in children up to age 16 years with rAOM. We planned to apply two main scenarios: grommets as a single surgical intervention and grommets as concurrent treatment with adenoidectomy (i.e. children in both the intervention and comparator groups underwent adenoidectomy). The comparators included active monitoring, antibiotic prophylaxis and placebo medication.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. Primary outcomes were: proportion of children who have no AOM recurrences at three to six months follow-up (intermediate-term) and persistent tympanic membrane perforation (significant adverse event). Secondary outcomes were: proportion of children who have no AOM recurrences at six to 12 months follow-up (long-term); total number of AOM recurrences, disease-specific and generic health-related quality of life, presence of middle ear effusion and other adverse events at short-term, intermediate-term and long-term follow-up. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics.

MAIN RESULTS

Five RCTs (805 children) with unclear or high risk of bias were included. All studies were conducted prior to the introduction of pneumococcal vaccination in the countries' national immunisation programmes. In none of the trials was adenoidectomy performed concurrently in both groups.Grommets versus active monitoringGrommets were more effective than active monitoring in terms of:- proportion of children who had no AOM recurrence at six months (one study, 95 children, 46% versus 5%; risk ratio (RR) 9.49, 95% confidence interval (CI) 2.38 to 37.80, number needed to treat to benefit (NNTB) 3; low-quality evidence);- proportion of children who had no AOM recurrence at 12 months (one study, 200 children, 48% versus 34%; RR 1.41, 95% CI 1.00 to 1.99, NNTB 8; low-quality evidence);- number of AOM recurrences at six months (one study, 95 children, mean number of AOM recurrences per child: 0.67 versus 2.17, mean difference (MD) -1.50, 95% CI -1.99 to -1.01; low-quality evidence);- number of AOM recurrences at 12 months (one study, 200 children, one-year AOM incidence rate: 1.15 versus 1.70, incidence rate difference -0.55, 95% -0.17 to -0.93; low-quality evidence).Children receiving grommets did not have better disease-specific health-related quality of life (Otitis Media-6 questionnaire) at four (one study, 85 children) or 12 months (one study, 81 children) than those managed by active monitoring (low-quality evidence).One study reported no persistent tympanic membrane perforations among 54 children receiving grommets (low-quality evidence).Grommets versus antibiotic prophylaxisIt is uncertain whether or not grommets are more effective than antibiotic prophylaxis in terms of:- proportion of children who had no AOM recurrence at six months (two studies, 96 children, 60% versus 35%; RR 1.68, 95% CI 1.07 to 2.65, I² = 0%, fixed-effect model, NNTB 5; very low-quality evidence);- number of AOM recurrences at six months (one study, 43 children, mean number of AOM recurrences per child: 0.86 versus 1.38, MD -0.52, 95% CI -1.37 to 0.33; very low-quality evidence).Grommets versus placebo medicationGrommets were more effective than placebo medication in terms of:- proportion of children who had no AOM recurrence at six months (one study, 42 children, 55% versus 15%; RR 3.64, 95% CI 1.20 to 11.04, NNTB 3; very low-quality evidence);- number of AOM recurrences at six months (one study, 42 children, mean number of AOM recurrences per child: 0.86 versus 2.0, MD -1.14, 95% CI -2.06 to -0.22; very low-quality evidence).One study reported persistent tympanic membrane perforations in 3 of 76 children (4%) receiving grommets (low-quality evidence).Subgroup analysisThere were insufficient data to determine whether presence of middle ear effusion at randomisation, type of grommet or age modified the effectiveness of grommets.

AUTHORS' CONCLUSIONS

Current evidence on the effectiveness of grommets in children with rAOM is limited to five RCTs with unclear or high risk of bias, which were conducted prior to the introduction of pneumococcal vaccination. Low to very low-quality evidence suggests that children receiving grommets are less likely to have AOM recurrences compared to those managed by active monitoring and placebo medication, but the magnitude of the effect is modest with around one fewer episode at six months and a less noticeable effect by 12 months. The low to very low quality of the evidence means that these numbers need to be interpreted with caution since the true effects may be substantially different. It is uncertain whether or not grommets are more effective than antibiotic prophylaxis. The risk of persistent tympanic membrane perforation after grommet insertion was low.Widespread use of pneumococcal vaccination has changed the bacteriology and epidemiology of AOM, and how this might impact the results of prior trials is unknown. New and high-quality RCTs of grommet insertion in children with rAOM are therefore needed. These trials should not only focus on the frequency of AOM recurrences, but also collect data on the severity of AOM episodes, antibiotic consumption and adverse effects of both surgery and antibiotics. This is particularly important since grommets may reduce the severity of AOM recurrences and allow for topical rather than oral antibiotic treatment.

Behavioral Signs of (Central) Auditory Processing Disorder in Children with Nonsyndromic Cleft Lip and/or Palate: A Parental Questionnaire Approach

Objective

Children with nonsyndromic cleft lip and/or palate often have a high prevalence of middle ear dysfunction. However, there are also indications that they may have a higher prevalence of (central) auditory processing disorder. This study used Fisher's Auditory Problems Checklist for caregivers to determine whether children with nonsyndromic cleft lip and/or palate have potentially more auditory processing difficulties compared with craniofacially normal children.

Methods

Caregivers of 147 school-aged children with nonsyndromic cleft lip and/or palate were recruited for the study. This group was divided into three subgroups: cleft lip, cleft palate, and cleft lip and palate. Caregivers of 60 craniofacially normal children were recruited as a control group. Hearing health tests were conducted to evaluate peripheral hearing. Caregivers of children who passed this assessment battery completed Fisher's Auditory Problems Checklist, which contains 25 questions related to behaviors linked to (central) auditory processing disorder.

Result

Children with cleft palate showed the lowest scores on the Fisher's Auditory Problems Checklist questionnaire, consistent with a higher index of suspicion for (central) auditory processing disorder. There was a significant difference in the manifestation of (central) auditory processing disorder-linked behaviors between the cleft palate and the control groups. The most common behaviors reported in the nonsyndromic cleft lip and/or palate group were short attention span and reduced learning motivation, along with hearing difficulties in noise.

Conclusion

A higher occurrence of (central) auditory processing disorder-linked behaviors were found in children with nonsyndromic cleft lip and/or palate, particularly cleft palate. Auditory processing abilities should not be ignored in children with nonsyndromic cleft lip and/or palate, and it is necessary to consider assessment tests for (central) auditory processing disorder when an auditory diagnosis is made for this population.

Trends in Otitis Media and Myringotomy With Tube Placement Among American Indian and Alaska Native Children and the US General Population of Children After Introduction of the 13-valent Pneumococcal Conjugate Vaccine

BACKGROUND

American Indian/Alaska Native (AI/AN) children have experienced higher otitis media (OM) outpatient visit rates than other US children. To understand recent trends, we evaluated AI/AN OM rates before and after 13-valent pneumococcal conjugate vaccine introduction.

METHODS

We analyzed outpatient visits listing OM as a diagnosis among AI/AN children <5 years of age from the Indian Health Service National Patient Information Reporting System for 2010-2013. OM outpatient visits for the general US child population <5 years of age were analyzed using the National Ambulatory Medical Care and National Hospital Ambulatory Care Surveys for 2010-2011.

RESULTS

The 2010-2011 OM-associated outpatient visit rate for AI/AN children (63.5 per 100/year) was similar to 2010-2011 rate for same-age children in the general US population (62.8) and decreased from the 2003 to 2005 AI/AN rate (91.4). Further decline in AI/AN OM visit rates was seen for 2010-2011 to 2012-2013 (P < 0.0001). The AI/AN infant OM visit rate (130.5) was 1.6-fold higher than the US infant population. For 2010-2011, the highest AI/AN OM visit rate for <5 year olds was from Alaska (135.0).

CONCLUSIONS

AI/AN <5-year-old OM visits declined by one third from 2003-2005 to 2010-2011 to a rate similar to the US general population <5 years. However, the AI/AN infant OM rate remained higher than the US infant population. The highest AI/AN <5-year-old OM rate occurred in Alaska.

Expression of calcium-binding proteins S100A8, S100A9 and S100A12 in otitis media

OBJECTIVES

Calgranulins (calcium-binding proteins S100A8, S100A9 and S100A12) are predominant cytoplasmic proteins of neutrophils and produced by various cells, playing multiple functions in innate immunity and the inflammatory process. Although up-regulated expression of S100A8 and S100A9 genes were observed in an animal model of otitis media (OM), their expressions have not been studied in human middle ear epithelial cells in response to the OM pathogen or in patients with recurrent or chronic OM (recurrent OM/RecOM or chronic OM with effusion/COME).

STUDY DESIGN

Gene expressions were compared between Streptococcus pneumoniae (SP)-infected and non-infected human middle ear epithelial cells (HMEECs) as well as between chronic OM patients and control patients (CI).

METHODS

Gene expressions were profiled by quantitative real time PCR (qPCR). S100 proteins in OM patient and CI middle ear biopsies were detected by immunostaining.

RESULTS

S100A8, S100A9 and S100A12 gene expressions were elevated in SP-infected HMEECs in time-dependent manner. S100A8 and S100A9 but not S100A12 gene expression was significantly elevated in the middle ear mucosa of OM patients. S100A8 and S100A9 protein were observed in middle ear mucosa of OM, but not CI patients. Minimal co-localization was observed between S100A8 and S100A9 with neutrophil elastase and cytokeratin in ME sections of OM patients.

CONCLUSION

Elevated S100A8 and S100A9 gene expression in SP-infected HMEECs and in the middle ear mucosa of OM, minor co-localized with neutrophil markers suggests that middle ear epithelial cell secretion of S100A8 and S100A9 may play a role in the pathogenesis of recurrent and chronic OM.

Recurrent acute otitis media detracts from health-related quality of life

OBJECTIVE

Acute otitis media causes discomfort to children and inconvenience to their parents. This study evaluated the quality of life in children with recurrent acute otitis media aged less than 24 months.

METHODS

Quality of life was evaluated in 149 children aged 10 to 24 months who were referred to the Oulu University Hospital on account of recurrent acute otitis media. The children were treated with or without surgery. Age-matched controls were selected randomly from the general child population. Parents completed the Child Health Questionnaire.

RESULTS

The children with recurrent acute otitis media had a significantly poorer quality of life than control children. The control children with a history of a few acute otitis media episodes had a significantly poorer quality of life than those without any such history. The quality of life of the children with recurrent acute otitis media improved during the one-year follow up, regardless of the treatment, but did not reach the same level as healthy children.

CONCLUSION

Acute otitis media detracted from quality of life when a generic measure was used. The mode of treatment used to prevent further recurrences of acute otitis media did not influence quality of life improvement.

Impact of Pediatric Acute Otitis Media on Child and Parental Quality of Life and Associated Productivity Loss in Malaysia: A Prospective Observational Study

BACKGROUND

Acute otitis media (AOM) affects both child and parental quality of life (QoL). Data on QoL associated with AOM in Malaysia is sparse, and the burden of indirect costs have not been previously reported.

OBJECTIVE

To determine the effect of pediatric AOM on child and parental QoL in Malaysia and its economic impact (indirect costs).

METHODS

We utilized a set of QoL questionnaires (PAR-AOM-QOL, OM-6, and EQ-5D) combined with questions addressing work/productivity loss and financial costs associated with caring for a child during his or her illness in an observational, multicenter, prospective study.

RESULTS

One hundred and ten AOM patients aged ≤5 years were included in the analysis. The majority of respondents were the patient's mother. Parental QoL was negatively affected for both emotional and daily disturbance scales, but the level of disturbance was low. Using OM-6, the greatest negative impact was on the child's QoL, followed by caregiver concerns, physical suffering, and emotional distress. Using EQ-5D, a moderately positive relationship between parents' emotional disturbance and daily disturbance, and a weak, negative correlation between parental emotional disturbance and parental health status was found. Parents with paid employment took an average of 21 h from work to care for their child, at an average cost of 321.8 Malaysian ringgit (US$97) in addition to their contribution to direct medical costs. Productivity losses whilst at work, uncompensated wage losses, and leisure time losses are also reported.

CONCLUSIONS

This study found that AOM is associated with some negative impact on parental QoL and significant economic impact at both patient and societal levels. The findings provide useful data on healthcare resource utilization and disease burden of AOM in Malaysia.

Parental views on otitis media: systematic review of qualitative studies

This study aims to describe parental experiences and perspectives of caring for a child with otitis media. We conducted a systematic review of qualitative studies on parental perspectives on caring for a child with otitis media. We searched electronic databases to July 2015. Seventeen studies involving 284 participants from six countries were included. We identified seven themes: diminishing competency (guilt over failure to identify symptoms, helpless and despairing, fear of complications, disempowered and dismissed); disrupting life schedules (disturbing sleep, interfering with work, burden on family); social isolation (stigma and judgement, sick consciousness); threatening normal development (delaying growth milestones, impairing interpersonal skills, impeding education); taking ownership (recognising symptoms, diagnostic closure, working the system, protecting against physical trauma, contingency planning); valuing support (needing respite, depending on community, clinician validation); and cherishing health (relief with treatment success, inspiring resilience).

CONCLUSION

The additional medical responsibilities and anxieties of parents caring for a child with otitis media, often discounted by clinicians, can be disempowering and disruptive. Chronicity can raise doubt about treatment efficacy and parental competency, and fears regarding their child's development. Care that fosters parental confidence and addresses their concerns about the child's development may improve treatment outcomes for children with otitis media.

WHAT IS KNOWN

• Otitis media is a leading cause of conductive hearing loss in children. • Parental perception of the treatment burden of otitis media can potentially affect their confidence and ability to care for their child. What is New: • We identified five themes to reflect parental perspectives: diminishing competency, disrupting life schedules, social isolation, threatening normal development, taking ownership, valuing support, and cherishing health. • Parents may perceive caring for a child with otitis media as disempowering and disruptive and with reoccurrence doubt treatment efficacy and their parental competency and develop fears regarding their child's development.

Impact of Early-Onset Acute Otitis Media on Multiple Recurrences and Associated Health Care Use

OBJECTIVE

To quantify the critical age period of first episode of acute otitis media (AOM) and its consequences for AOM recurrences and AOM health care use.

STUDY DESIGN

Children enrolled in the Wheezing-Illnesses-STudy-LEidsche-Rijn cohort with at least 1 episode of AOM documented in their primary care health record before 2 years of age were followed until 6 years of age. Data on episodes of AOM and associated primary care consultations, antibiotic prescriptions, and specialist referrals were retrieved. Regression models assessed the presence and shape of the associations between age of first AOM and subsequent episodes of AOM and health care use.

RESULTS

A total of 796 of 2026 children (39%) experienced a first AOM before 2 years of age. Each month decrease in age at first AOM in the first 2 years of life increased the risk of developing recurrent AOM (≥3 AOM episodes in 6 months or ≥ 4 in 1 year) linearly by 6% (adjusted risk ratio: 1.06; 95% CI: 1.02-1.10). For first AOM occurring before 9 months, the cumulative 6-year primary care consultation rate increased by 8% (adjusted incidence rate ratio: 1.08; 95% CI: 1.03-1.15) and the associated specialist referral increased by 16% (adjusted risk ratio: 1.16; 95% CI: 1.07-1.27) for each month decrease in age. No associations were found between age at first AOM and total AOM episodes or antibiotic prescriptions.

CONCLUSIONS

The association between earlier age of first AOM and recurrent AOM as well as total health care use during childhood is particularly strong before 9 months of age.

Acute otitis media with spontaneous tympanic membrane perforation

The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

Otitis media

Otitis media (OM) or middle ear inflammation is a spectrum of diseases, including acute otitis media (AOM), otitis media with effusion (OME; 'glue ear') and chronic suppurative otitis media (CSOM). OM is among the most common diseases in young children worldwide. Although OM may resolve spontaneously without complications, it can be associated with hearing loss and life-long sequelae. In developing countries, CSOM is a leading cause of hearing loss. OM can be of bacterial or viral origin; during 'colds', viruses can ascend through the Eustachian tube to the middle ear and pave the way for bacterial otopathogens that reside in the nasopharynx. Diagnosis depends on typical signs and symptoms, such as acute ear pain and bulging of the tympanic membrane (eardrum) for AOM and hearing loss for OME; diagnostic modalities include (pneumatic) otoscopy, tympanometry and audiometry. Symptomatic management of ear pain and fever is the mainstay of AOM treatment, reserving antibiotics for children with severe, persistent or recurrent infections. Management of OME largely consists of watchful waiting, with ventilation (tympanostomy) tubes primarily for children with chronic effusions and hearing loss, developmental delays or learning difficulties. The role of hearing aids to alleviate symptoms of hearing loss in the management of OME needs further study. Insertion of ventilation tubes and adenoidectomy are common operations for recurrent AOM to prevent recurrences, but their effectiveness is still debated. Despite reports of a decline in the incidence of OM over the past decade, attributed to the implementation of clinical guidelines that promote accurate diagnosis and judicious use of antibiotics and to pneumococcal conjugate vaccination, OM continues to be a leading cause for medical consultation, antibiotic prescription and surgery in high-income countries.

The Impact of Childhood Acute Otitis Media on Parental Quality of Life in a Prospective Observational Cohort Study

Background and Objectives

Acute otitis media (AOM) not only affects childhood quality of life (QoL), but can also affect parental QoL. We adapted a previously published questionnaire on the effect of childhood recurrent ear, nose and throat infections on parental QoL for use with AOM and used it in an observational, multicentre, prospective study of children with AOM.

Methods

The AOM-specific parental QoL questionnaire grouped 15 items into emotional, daily disturbance, total and overall parental QoL impact scores. The questionnaire was assessed using item-convergent and item-discriminant validity criteria and internal consistency reliability; and then used with parents of children aged <6 years diagnosed with AOM at 73 practices in Germany, Italy, Spain, Sweden and the UK. Bivariate analyses explored the differences in mean parental QoL impact scores by various characteristics.

Results

The questionnaire demonstrated good to excellent internal consistency reliability for the various components (Cronbach’s α 0.82–0.97). There were 1419 AOM episodes among 5882 healthy children over 1 year, of which 1063 episodes (74.9 %) among 852 children had a questionnaire. Parents reported interrupted sleep (68.4 %), worry (51.0 %), altered daily schedule (44.6 %) and less leisure time (41.5 %) with a score ≥3 (1 = least to 5 = most impact). Factors that adversely affected parental QoL included: increased parental perception of AOM severity, younger child age and multiple AOM episodes.

Conclusions

The AOM-specific parental QoL questionnaire demonstrated good performance across five European countries. Parental QoL was affected by childhood AOM proportionally to severity, number of episodes and younger child age.

Caregiver Quality of Life Is Related to Severity of Otitis Media in Children

OBJECTIVE

Otitis media (OM) in children is the most frequent reason for physician visits in developed countries and burdens caregivers, society, and the child. Our objective was to describe the impact of OM severity on parent/caregiver quality of life (QoL).

STUDY DESIGN

Multi-institutional prospective cross-sectional study.

SETTING

Otolaryngology, family, and pediatric practices.

SUBJECTS AND METHODS

Children 6 to 24 months old with and without a primary diagnosis of recurrent OM and their caregivers. Physicians provided patient history, and parents/caregivers completed a Family Information Form, the PedsQL Family Impact survey, the Patient Reported Outcomes Measurement Information System (PROMIS) survey, and the OM 6-item severity survey (OM-6).

RESULTS

A total of 2413 subjects were enrolled and data from 1208 patients and physician were analyzed. The average child age was 16 months, and 54% were male. The mean OM-6 score was 3.2. The mean PedsQL Family Impact score for parents was 66.9 from otolaryngology sites and 78.8 from pediatrics/family practice sites (P < .001). Higher (worse) OM-6 scores correlated significantly with worse PedsQL Family Impact scores (Pearson r = -0.512, P < .01). Similarly, increasing OM-6 scores strongly correlated with increased parental anxiety, depression, and fatigue, as well as decreased satisfaction (all P < .01).

CONCLUSIONS

Worse PedsQL Family Impact and PROMIS scores were highly correlated with elevated OM-6 scores, suggesting that severity of childhood OM significantly affects parent/caregiver QoL. Understanding the impact of a child's illness on parent/caregiver QoL can help physicians counsel patients and families and provide better family-centered, compassionate care.

Quality of life after surgery for recurrent otitis media in a randomized controlled trial

BACKGROUND

Tympanostomy with or without adenoidectomy is effective in preventing recurrences of acute otitis media (RAOM), but little is known about the effect of these operations on the quality of life (QOL). We evaluated the efficacy of insertion of tympanostomy tubes with and without adenoidectomy for improving QOL in young children in a controlled, randomized trial.

METHODS

QOL was evaluated in the 159 children aged 10 months to 2 years participating in our larger study in which children with RAOM were randomly assigned to receive tympanostomy tubes, tympanostomy tubes with adenoidectomy or neither. The caregiver of the child completed otitis media-specific QOL questionnaires (Otitis Media-6) at entry and after 4 months and 12 months of follow up.

RESULTS

Scores on the global ear-related QOL and the subsets of caregiver concern, emotional distress and physical suffering in the questionnaires improved with time during the follow up, but the groups did not differ from each other.

CONCLUSIONS

QOL in children with RAOM improves with time when the subjects are closely followed. Tympanostomy with adenoidectomy does not provide any additional QOL benefit for children with RAOM, even though these operations are effective in preventing further otitis media episodes.

Impact of early daycare on healthcare resource use related to upper respiratory tract infections during childhood: prospective WHISTLER cohort study

BACKGROUND

Daycare attendance is an established risk factor for upper respiratory tract infections (URTI) and acute otitis media (AOM). Whether this results in higher use of healthcare resources during childhood remains unknown. We aim to assess the effect of first year daycare attendance on the timing and use of healthcare resources for URTI and AOM episodes during early childhood.

METHODS

In the Wheezing-Illnesses-STudy-LEidsche-Rijn birth cohort, 2,217 children were prospectively followed up to age six years. Children were categorized according to first-year daycare attendance (yes versus no) and age at entry when applicable (age 0 to 2 months, 3 to 5 months and 6 to 12 months). Information on general practitioner (GP) diagnosed URTI and AOM, GP consultations, antibiotic prescriptions and specialist referral was collected from medical records. Daycare attendance was recorded by monthly questionnaires during the first year of life.

RESULTS

First-year daycare attendees and non-attendees had similar total six-year rates of GP-diagnosed URTI and AOM episodes (59/100 child-years, 95% confidence interval 57 to 61 versus 56/100 child-years, 53 to 59). Daycare attendees had more GP-diagnosed URTI and AOM episodes before the age of one year and fewer beyond the age of four years than non-attendees (Pinteraction <0.001). Daycare attendees had higher total six-year rates for GP consultation (adjusted rate ratio 1.15, 1.00 to 1.31) and higher risk for specialist referrals (hazard ratio: 1.43, 1.01 to 2.03). The number of antibiotic prescriptions in the first six years of life was only significantly increased among children who entered daycare between six to twelve months of age (rate ratio 1.32, 1.04 to 1.67). This subgroup of child-care attendees also had the highest overall URTI and AOM incidence rates, GP consultation rates and risk for specialist referral.

CONCLUSIONS

Children who enter daycare in the first year of life, have URTI and AOM at an earlier age, leading to higher use of healthcare resources compared to non-attendees, especially when entering daycare between six to twelve months. These findings emphasize the need for improved prevention strategies in daycare facilities to lower infection rates at the early ages.

Impact of Otitis Media Severity on Children's Quality of Life

OBJECTIVE

Children with otitis media (OM) suffer sleep disturbances, loss of appetite, earache, and behavioral problems. Our objective was to quantitate the average burden of OM and to compare the associated impact of tympanostomy tubes on infant health related quality of life (HR-QoL).

STUDY DESIGN

Multi-institutional prospective cross-sectional study.

SETTING

Otolaryngology, family practice, and pediatric clinics.

SUBJECTS AND METHODS

Children ages 6 to 24 months of age with or without recurrent OM. Patient history, the PedsQL Infant QoL survey, and the 6-item child with OM survey (Otitis Media 6 [OM-6]) were collected from providers and parents.

RESULTS

Data from 1208 patients were analyzed. Mean age was 14.7 months, and 54% were male. The mean OM-6 score of children with recurrent OM was 3.3, whereas similarly aged well-children had a mean OM-6 score of 2.5. The mean PedsQL Infant scores of recurrent OM patients were significantly worse than those of children from well-child visits. Worse OM-6 scores were correlated with poorer PedsQL Infant scores, Pearson r = -0.581 (1-12 months) and -0.558 (13-24 months), P < .001. Otolaryngology patients who were recommended to undergo ear tube placement had significantly poorer OM-6 scores and worse PedsQL Infant scores, whereas patients with prior tube placement had significantly better OM-6 and PedsQL Infant scores.

CONCLUSION

Children with recurrent OM had significantly worse HR-QoL than similarly aged healthy children. Increased burden of OM strongly affected HR-QoL, and recommendation for tube placement was associated with increased disease burden and poorer HR-QoL. The presence of tympanostomy tubes was associated with better OM-6 and PedsQL Infant scores.

Psychosocial outcomes of children with ear infections and hearing problems: a longitudinal study

Background

There is some evidence of a relationship between psychosocial health and the incidence of ear infections and hearing problems in young children. There is however little longitudinal evidence investigating this relationship. This paper used 6-year prospective longitudinal data to examine the impact of ear infection and hearing problems on psychosocial outcomes in two cohorts of children (one cohort recruited at 0/1 years and the other at 4/5 years).

Methods

Data from the Longitudinal Study of Australian Children (LSAC) were analysed to address the research aim. The LSAC follows two cohorts of children (infants aged 0/1 years – B cohort, n = 4242; and children aged 4/5 years – K cohort, n = 4169) collecting data in 2004, 2006, 2008 and 2010. In B cohort at baseline 3.7% (n = 189) of the sample were reported by their parent to have had an ear infection (excluding hearing problems) and 0.5% (n = 26) were reported by their parent to have hearing problems (excluding ear infections). 6.7% (n = 323) of the K cohort were identified as having had an ear infection and 2.0% (n = 93) to have hearing problems. Psychosocial outcomes were measured using the Strengths and Difficulties Questionnaire. Data were analysed using multivariate analysis of variance and logistic regression, reporting adjusted odds ratio and 95% confidence intervals of the association between reported ear infections (excluding hearing problems)/or hearing problems (excluding ear infections) and psychosocial outcomes.

Results

Children were more likely to have abnormal/borderline psychosocial outcomes at 10/11 years of age if they had been reported to have ongoing ear infections or hearing problems when they were 4/5 years old. When looking at the younger cohort however, poorer psychosocial outcomes were only documented at 6/7 years for children reported to have hearing problems at 0/1 years, not for those who were reported to have ongoing ear infections.

Conclusion

This study adds further evidence that a relationship may exist between repeated ear infections or hearing problems and the long-term psychosocial health of children and provides support for a more systematic investigation of these issues.

The impact of influenza-like illness in young children on their parents: a quality of life survey

Background

Influenza-like illness can cause excess paediatric morbidity and burden on parents.

Objectives

We determined the quality of life (QoL) impact of children’s influenza-like illness (ILI) on their parents.

Methods

We conducted a prospective cohort study in childcare centres and a general practice in Sydney, Australia. Using PAR-ENT-QoL, we measured QoL of parents of children aged 6 months–3 years before the 2010 influenza season, then again for parents of children with ILI (ILI group) using SF-12v2 Acute Form and PAR-ENT-QoL, and contemporaneously for parents of aged-matched children without ILI (non-ILI group).

Results

Of 381 children enrolled from 90 childcare centres, 105 developed ILI. PAR-ENT-QoL scores of the ILI group were significantly lower in the post-ILI follow-up interviews than at baseline (60.99 vs. 79.77, p < 0.001), and those of non-ILI group at follow-up interviews (60.99 vs. 84.05, p < 0.001). SF-12v2 scores of the ILI group were also significantly lower than those of non-ILI group: physical component summary (50.66 vs. 53.16, p = 0.011) and mental component summary (45.67 vs. 53.66, p < 0.001). Two factors were significantly associated with parental QoL: total time spent caring child during ILI and whether the child had severe ILI or not. Correlations between PAR-ENT-QoL and SF-12v2 scores were satisfactory.

Conclusions

Parents had significantly lower QoL while their child had ILI, compared with before ILI and with parents of children without ILI. The public health impact of ILI in children on the QoL in families is far from negligible. QoL measurement can complement economic evaluation of ILI disease burden and provide a more complete picture of impact.

Longitudinal analysis of ear infection and hearing impairment: findings from 6-year prospective cohorts of Australian children

Background

Middle ear infection is common in childhood. Despite its prevalence, there is little longitudinal evidence about the impact of ear infection, particularly its association to hearing loss. By using 6-year prospective data, we investigate the onset and impact over time of ear infection in Australian children.

Methods

We analyse 4 waves of the Longitudinal Study of Australian Children (LSAC) survey collected in 2004, 2006, 2008, and 2010. There are two age cohorts in this study (B cohort aged 0/1 to 6/7 years N=4242 and K cohort aged 4/5 to 10/11 years N=4169). Exposure was parent-reported ear infection and outcome was parent-reported hearing problems. We modelled ear infection onset and subsequent impact on hearing using multivariate logistic regressions, reporting Adjusted Odds Ratios (AOR) and Confidence Intervals (95% CI). Separate analyses were reported for indigenous and non-indigenous children.

Results

Associations of ear infections between waves were found to be very strong both among both indigenous and non-indigenous children in the two cohorts. Reported ear infections at earlier wave were also associated with hearing problems in subsequent wave. For example, reported ear infections at age 4/5 years among the K cohort were found to be predictors of hearing problems at age 8/9 years (AOR 4.0, 95% CI 2.2-7.3 among non-indigenous children and AOR 7.7 95% CI 1.0-59.4 among indigenous children). Number of repeated ear infections during the 6-year follow-up revealed strong dose–response relationships with subsequent hearing problems among non-indigenous children (AORs ranged from 4.4 to 31.7 in the B cohort and 4.4 to 51.0 in the K cohort) but not statistically significant among indigenous children partly due to small sample.

Conclusions

This study revealed the longitudinal impact of ear infections on hearing problems in both indigenous and non-indigenous children. These findings highlight the need for special attention and follow-up on children with repeated ear infections.

Tympanostomy with and without adenoidectomy for the prevention of recurrences of acute otitis media: a randomized controlled trial

BACKGROUND

The prevention of otitis media, particularly among infants, remains a controversial issue. We evaluated the efficacy of insertion of tympanostomy tubes with and without adenoidectomy for preventing recurrent acute otitis media (AOM) in young children.

METHODS

We randomly assigned 300 children aged 10 months to 2 years who had recurrent AOM to groups receiving tympanostomy tubes (Tymp) (n = 100), tympanostomy tubes with adenoidectomy (TympAde) (n = 100) or neither (Contr) (n = 100). All the children were followed up for 12 months.

RESULTS

The primary outcome was intervention failure (2 AOM episodes in 2 months, 3 in 6 months or persistent effusion lasting for 2 months). Intervention failed in 21% of cases (21/100) in the Tymp group, 16% (16/100) in the TympAde group and 34% (34/100) in the Contr group. The absolute differences were -13% [95% confidence interval (CI) -25% to -1%, P = 0.04] between the Tymp and Contr groups and -18% (95% CI -30 to -6%, P =0.004) between the TympAde and Contr groups.

CONCLUSIONS

Insertion of tympanostomy tubes alone or with adenoidectomy was effective in preventing recurrent AOM episodes in children younger than 2 years of age.

Quality of life in children with recurrent acute otitis media in southwestern of iran

Otitis media (OM) is one of the most common disorders in childhood and may have a considerable impact on quality of life and functional health status of children. The aim of the study was to assess the quality of life in children with recurrent acute otitis media before and after the treatment by using a questionnaire. A multicentre survey base study. This study was conducted at Imam Khomeini and Apadana Hospitals in the southwestern region of Iran between Sep 2008 and March 2009. Regardless of primary complaint, all patients completed a demographic, health-related quality of life (HRQoL) and OM-6 surveys. A total of 246 patients included in this study. The mean age of patients in this study was 2.62 years. One month follow-up questionnaires were obtained from 180 patients for a 73.17% response rate, and 12 weeks follow-up questionnaires were obtained from 150 patients for a 61.38% response rate. The children with recurrent AOM had poorer scores t. Quality of life of children with three or more episodes of AOM in the preceding year was poorer than that of children with 2-3 episodes.

Societal costs and burden of otitis media in Portugal

This study aimed to estimate the resource consumption and societal impact of otitis media (OM) in children younger than five years of age in Portugal. An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or "running ear" and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.

Otitis media and associations with overweight status in toddlers

INTRODUCTION

Otitis media (OM) is a significant disease that affects nearly all children early in life. Recently, childhood overweight has become an epidemic. Past research has demonstrated that a history of OM is related to food preferences and overweight through proposed physiological mechanisms. The purpose of this study was to explore the relationship between recurrent OM (ROM)/tympanostomy tube treatment and overweight status.

METHODS

Data were analyzed from a prospective cohort of mothers and children recruited from 1991-1996 from a local health maintenance organization. ROM and tympanostomy tube status were obtained through a combination of physical exam and medical record abstraction. ROM and tympanostomy tube status were analyzed as categorical variables with weight-for-length (WFL) data from well child checks. Chi-square and logistic regression for univariate and multivariate analyses were performed.

RESULTS

11.4% of children had a WFL measure at two years of age ≥ 95 th percentile. Those children with a history of tympanostomy tube treatment had a significantly increased risk of having a WFL ≥ 95 th percentile after controlling for birth weight, maternal prenatal smoking, maternal education, and family income (OR 3.32, 95% CI 1.43-7.72). The alternative hypothesis that children with larger WFL at two month of age would have a greater number of OM episodes by two years of age was not significant.

CONCLUSION

The findings of this study are consistent with the hypothesis and prior research that OM treated with tympanostomy tubes is associated with overweight status.

Otitis media across nine countries: disease burden and management

OBJECTIVE

To assess the perceived disease burden and management of otitis media (OM) among an international cohort of experienced physicians.

METHODS

A cross-sectional survey conducted in France, Germany, Spain, Poland, Argentina, Mexico, South Korea, Thailand and Saudi Arabia. Face-to-face interviews conducted with 1800 physicians (95% paediatricians, 5% family practitioners).Main outcome measures were the perceived burden on clinical practice (number of cases, complications and referrals) and first- and second-line management strategies for OM. Results are expressed as mean and range across the nine countries over three continents.

RESULTS

Respondents estimated an average annual caseload of 375 (range 128-1003) children under 5 years of age with OM; 54% (range 44-71%) with an initial episode and 38% (range 27-54%) with recurrent OM (ROM). OM with complications was estimated to be approximately 20 (range 7-49) cases per year and an estimated 15% (8-41%) of children with OM was recalled as needing specialist referral. There was high awareness of Streptococcus pneumoniae and Haemophilus influenzae as causative bacterial pathogens: 77% (range 65-91%) and 74% (range 68-83%), respectively, but less recognition of non-typeable H. influenzae (NTHi); 59% (range 45-67%). Although concern over antimicrobial resistance was widespread, empirical treatment with antibiotics was the most common first-line treatment (mean 81%, range 40-96%). The burden of disease is substantial enough that many physicians would consider vaccination to prevent OM (mean score 5.1, range 4.3-6.2 on 1-7 scale).

CONCLUSIONS

This large, multinational survey shows that OM remains a significant burden for clinical practice. Despite awareness of shortcomings, antimicrobial therapy remains the most frequent treatment for OM.

Quality of life of children and their caregivers during an AOM episode: development and use of a telephone questionnaire

BACKGROUND

The negative consequences of acute otitis media (AOM) on the quality of life (QOL) of children and their families need to be measured to assess benefits of preventive interventions.

METHODS

A new questionnaire was specifically designed for use in telephone surveys. A random sample of Canadian families was selected using random-digit dialling. Caregivers of children 6-59 months of age who experienced at least one AOM episode during the last 12 months were interviewed. Multidimensional severity and global QOL scores were measured both for affected children and their caregivers. Internal consistency of scores was assessed using standard tests.

RESULTS

Of the 502 eligible caregivers who completed the survey, 161 (32%) reported at least one AOM episode during the last 12 months and these cases were included in the analysis. Average severity was 2.6 for children and 2.4 for caregivers on a 1 to 4 scale (maximum severity). Cronbach alpha values were 0.78 and 0.81 for the severity score of children and caregivers respectively. Average QOL was 3.4 for children and 3.5 for caregivers on a 1 to 5 scale (best QOL). There was moderate to high correlation between severity and QOL scores, and between these scores and duration of AOM episodes.

CONCLUSIONS

The questionnaire was easy to use during telephone interviews and results suggest good reliability and validity of the different scores to measure AOM severity and QOL of children and their caregivers during an AOM episode.

Current and Future Prospects for a Vaccine for Nontypeable Haemophilus influenzae

Nontypeable Haemophilus influenzae is an important human respiratory tract pathogen that causes about 30% of otitis media in infants and children. This proportion is increasing as a result of pneumococcal conjugate vaccines. Because of the morbidity associated with otitis media, a strong rationale exists to develop strategies to prevent these infections. A challenge to developing a vaccine for nontypeable H. influenzae is the antigenic heterogeneity of several major surface antigens and the genetic heterogeneity among strains. Several research groups have identified conserved surface proteins and tested them as putative vaccines. A recent clinical trial with protein D, a conserved surface antigen, demonstrated partial efficacy in preventing H. influenzae otitis media. This important result provides a proof of principle for developing a vaccine to prevent otitis media caused by nontypeable H. influenzae. Several vaccine antigens for nontypeable H. influenzae are in development.

Challenges in reducing the burden of otitis media disease: an ENT perspective on improving management and prospects for prevention

Acute otitis media (AOM) is a major public health concern. This frequent disease of childhood is a leading cause of physician visits, a major component of paediatric healthcare burden, and a key contributor to antibiotic resistance. An international expert group comprising mainly ear, nose, and throat physicians met in June 2008 to discuss the optimal management of AOM, particularly with regards to unmet needs in diagnosis and management. Current guidelines do not help identify which patients are most at risk for severe or complicated AOM. Diagnosis of AOM is also complicated by a lack of correlation between clinical signs and symptoms and responsible pathogens. Consequently, treatment of AOM is not always appropriate, and the long-term overuse of antibiotics in AOM reduces the effectiveness of treatment and places children at risk for drug-resistant infections. There is a need for educational and research initiatives to improve diagnostic accuracy and management of AOM. Because there is currently no ideal treatment, vaccination is an attractive additional approach for managing AOM and reducing its burden.

Quality of life outcomes after ventilating tube insertion for otitis media in an Australian population

OBJECTIVE

To assess the change in quality of life in a group of Australian children with recurrent acute otitis media (AOM) and/or otitis media with effusion (OME) who were treated with ventilating tube (VT) insertion.

METHODS

Prospective pre- and post-intervention outcome study at the Women's and Children's Hospital, North Adelaide, South Australia. The Otitis Media 6-item (OM-6) survey was used as a measure of disease-specific quality of life prior to surgery and then again at 6 weeks post-operatively. Any patients who were listed for any additional ear, nose or throat (ENT) procedures at the same time were excluded.

RESULTS

Complete responses for both pre- and post-surgery questionnaires were obtained from the parents of 53 patients. The age range was 11 months to 15.4 years (average 5.1 years), and 39.6% (n=21) were suffering from recurrent AOM whilst the remaining 60.4% (n=32) were suffering from OME. Overall ear-related quality of life was found to improve significantly following insertion of ventilating tubes (p<0.001), as was the mean OM-6 score (p<0.001). Furthermore, statistically significant improvements were noted in each individual domain making up the OM-6 survey (physical suffering, hearing loss, speech impairment, emotional distress, activity limitations and caregiver concerns).

CONCLUSIONS

The disease-specific quality of life of a group of Australian pediatric patients with otitis media was found to significantly improve following insertion of ventilating tubes as measured by the OM-6 survey. Improvements were found in global ear-related quality of life, in the mean OM-6 score, as well as in all individual domains of the OM-6 survey.

Psychosocial effects on caregivers for children on chronic peritoneal dialysis

The study was designed to explore the psychosocial effects on caretakers of children in Taiwan on chronic peritoneal dialysis (CPD). This is a case-control study, performed with subjects drawn from eight medical centers. The study group consisted of caretakers of 32 children with renal failure being treated with CPD. For comparison, a control group of caretakers of 64 healthy children as well as the regional Taiwanese studies were used. Two instruments were used to explore the presence of probable depression and quality of life (QOL) of the caretakers: the Taiwanese Depression Questionnaire, and the World Health Organization QOL BRIEF-Taiwan Version. In the study group, only 25% of caregivers had full-time jobs, and 66% of families had an annual income of less than US dollar 15,000. Of the 32 families in the study group, 16% had only a single parent. The prevalence of probable depression was significantly more common in the study group compared with control and referent group (28% vs 5% and 9.44%; P = 0.001). QOL scores in four domains were also significantly lower in the study group. In conclusion, even with the advances of peritoneal dialysis techniques, caring for children on CPD in Taiwan has significant adverse psychosocial effects on the primary caregivers. Attention should be paid to the psycho-social status of the caregivers.

Traffic-related air pollution and otitis media

BACKGROUND

Otitis media is one of the most common infections in young children. Although exposure to environmental tobacco smoke is a known risk factor associated with otitis media, little information is available regarding the potential association with air pollution.

OBJECTIVE

We set out to study the relationship between exposure to traffic-related air pollution and otitis media in two birth cohorts.

METHODS

Individual estimates of outdoor concentrations of traffic-related air pollutants-nitrogen dioxide, fine particles [particulate matter with aerodynamic diameters </= 2.5 microm (PM2.5)], and elemental carbon-were calculated for home addresses of approximately 3,700 and 650 infants from birth cohort studies in the Netherlands and Germany, respectively. Air pollution exposure was analyzed in relation to physician diagnosis of otitis media in the first 2 years of life.

RESULTS

Odds ratios (adjusted for known major risk factors) for otitis media indicated positive associations with traffic-related air pollutants. An increase in 3 microg/m3 PM2.5, 0.5 microg/m3 elemental carbon, and 10 microg/m3 NO2 was associated with odds ratios of 1.13 (95% confidence interval, 1.00-1.27) , 1.10 (1.00-1.22) , and 1.14 (1.03-1.27) in the Netherlands and 1.24 (0.84-1.83) , 1.10 (0.86-1.41) , and 1.14 (0.87-1.49) in Germany, respectively.

CONCLUSIONS

These findings indicate an association between exposure to traffic-related air pollutants and the incidence of otitis media. Given the ubiquitous nature of air pollution exposure and the importance of otitis media to children's health, these findings have significant public health implications.
