Age inconsistency in the American Academy of Pediatrics guidelines for acute otitis media

Early Antibiotics and Childhood Obesity: Do Future Risks Matter to Parents and Physicians?

To understand how parents and physicians make decisions regarding antibiotics and whether a potential associated risk of obesity would alter decisions, we conducted a qualitative study of parents and physicians who care for children. Parent focus groups and physician interviews used a guide focused on experience with antibiotics and perceptions of risks and benefits, including obesity. Content analysis was used to understand how a risk of obesity would influence antibiotic decisions. Most parents (n = 59) and physicians (n = 22) reported limited discussion about any risks at the time of antibiotic prescriptions. With an acute illness, most parents prioritized symptomatic improvement and chose to start antibiotics. Physicians' treatment preferences were varied. An obesity risk did not change most parents' or physicians' preferences. Given that parent-physician discussion at the time of acute illness is unlikely to change preferences, public health messaging may be a more successful approach to counter obesity and antibiotics overuse.

Achados timpanométricos em um grupo de escolares

OBJETIVO: caracterizar e comparar os achados timpanométricos de um grupo de escolares. MÉTODO: foram avaliados 112 escolares, de ambos os gêneros, na faixa etária de quatro anos a cinco anos e onze meses que frequentavam uma Escola Municipal de Educação Infantil, localizada em um bairro periférico da cidade de Marília. Como procedimento de triagem, utilizou-se a timpanometria. Considerou-se que a criança PASSOU na triagem quando apresentou curva timpanométrica do tipo A, bilateralmente, sendo reavaliada em caso de falha. RESULTADOS: observou-se um alto índice de falha (63,4%) na população estudada. Os escolares de maior faixa etária e do gênero feminino apresentaram um índice maior de timpanogramas do tipo A, em ambas as orelhas. Houve uma maior incidência de falha nas crianças de faixa etária entre 4 anos e 4 anos e 11 meses, e do gênero masculino. CONCLUSÃO: nesta amostra obteve-se um alto índice de alterações timpanométricas. Houve uma tendência de escolares do gênero masculino e de menor faixa etária apresentarem um índice maior de alterações timpanométricas quando comparados ao gênero feminino e de maior faixa etária, não sendo esta diferença estatisticamente significante.

Panel 7: Treatment and comparative effectiveness research

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.

A challenge to appropriate antibiotic use in children with respiratory infections: a 5-year single-institution experience

BACKGROUND

We have studied the rate of emergence of antibiotic-resistant Streptococcus pneumoniae (S. pneumoniae) and Haemophilus influenzae (H. influenzae) and the subsequent antibiotic use in host patients of those isolates at the Department of Pediatrics, Soma General Hospital, Fukushima. Moreover, we carried out several studies investigating the risks and benefits of antibiotic-free treatment for children with respiratory infections. In this report, we summarize our research and suggest better treatment options for pediatric patients with respiratory infections.

METHODS

We investigated the necessity of antibiotic use in the treatment of pediatric inpatients with respiratory syncytial virus (RSV) infection, and tested our hypothesis that antibiotic-free treatment for common cold will reduce the number of resistant S. pneumoniae strains in the pediatric nasopharynx. Therefore, we restricted prescribing antibiotics for pediatric patients with respiratory infections. The rates of resistant S. pneumoniae and H. influenzae and the medication history of the host patients before and after the intervention were compared.

RESULTS

We found that most of the RSV-infected patients recovered without antibiotic treatment, and that the antibiotic-free treatment inhibited the emergence of antibiotic-resistant strains. The rate of penicillin-resistant S. pneumoniae decreased but the rate of ampicillin-resistant H. influenzae did not change significantly during the study.

CONCLUSION

We concluded that patients with respiratory infections can be treated without antibiotics, under careful examination and observation. Continued monitoring of such new interventions as well as recommending their use to other caregivers and physicians will help inhibit the spread of resistant strains.

Poor adherence to antibiotic prescribing guidelines in acute otitis media--obstacles, implications, and possible solutions

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.

Ceftriaxone for refractory acute otitis media: impact of a clinical practice guideline

OBJECTIVE

To determine the effect of a clinical practice guideline (CPG) on the use of ceftriaxone for the treatment of refractory acute otitis media (AOM) at a tertiary care pediatric hospital.

METHODS

Charts of all patients aged 3 to 60 months referred from an emergency department to a day treatment center for management of refractory AOM with ceftriaxone were reviewed. Data were collected during two 18-month periods before and after implementation of a CPG developed by a local group of experts. Ceftriaxone was indicated for children with symptomatic AOM despite 48 hours of treatment with high-dosage amoxicillin or amoxicillin-clavulanate (>75 mg/kg per day) or despite receiving 1 of these 2 antibiotics over the previous month. Overall treatment was considered adequate if patients met these indications for ceftriaxone, if at least 3 daily doses had been prescribed, and if all doses were within the 40- to 60-mg/kg range.

RESULTS

Thirty-two emergency physicians referred 127 patients to the day treatment center (60 preimplementation and 67 postimplementation of the CPG). The mean (SD) patient ages were 16.7 (7.4) and 19.7 (12.4) months in the preimplementation and postimplementation groups, respectively. Indications for prescription of ceftriaxone were adequate in 16.7% of the preguideline and 22.4% of the postguideline groups (P = 0.4). Physicians were twice as likely to use ceftriaxone adequately after the guideline's implementation, but this result was not statistically significant (crude odds ratio, 2.2; 95% confidence interval, 0.5-9.0).

CONCLUSIONS

Implementation of a CPG for the treatment of refractory AOM with ceftriaxone did not improve indications for its use.

Antibiotics versus placebo or watchful waiting for acute otitis media: a meta-analysis of randomized controlled trials

BACKGROUND

Recommendations on withholding antibiotics in children with acute otitis media (AOM) have been inadequately implemented in clinical practice.

OBJECTIVES

We evaluated the role of prescribing antibiotics for AOM.

METHODS

We performed a meta-analysis of randomized controlled trials (RCTs) that were retrieved from searches performed in the PubMed and Cochrane databases, and compared antibiotic treatment with placebo or watchful waiting (delayed antibiotic treatment if clinically indicated) for patients with AOM.

RESULTS

We identified seven trials comparing antibiotic treatment with placebo (all double-blinded) and four trials comparing antibiotic treatment with watchful waiting (two investigator-blinded and two open-label) trials, all of which involved children (6 months to 12 years). Clinical success was more likely with antibiotics than comparator treatment in: placebo-controlled trials [seven RCTs, 1405 patients, risk ratio (RR) = 1.11, 95% confidence interval (CI) = 1.05-1.18]; watchful waiting trials (four RCTs, 915 patients, RR = 1.18, 95% CI = 1.07-1.32); and all trials combined (11 RCTs, 2320 patients, RR = 1.13, 95% CI = 1.08-1.19). Similarly, persistence of symptoms 2-4 days after treatment initiation was less likely with antibiotics in: placebo-controlled trials (four RCTs, 1014 patients, RR = 0.75, 95% CI = 0.64-0.88) and all trials combined (five RCTs, 1299 patients, RR = 0.68, 95% CI = 0.54-0.85). Diarrhoea was more likely with antibiotics (seven RCTs, 1807 patients, RR = 1.50, 95% CI = 1.16-1.95). No differences between the compared treatments were found regarding other effectiveness and safety outcomes.

CONCLUSIONS

Antibiotic treatment is associated with a more favourable clinical course in children with AOM, compared with placebo, and also compared with watchful waiting. However, safety issues and the rather small treatment effect difference render the consideration of additional factors necessary in relevant clinical decision making.

Valuing reduced antibiotic use for pediatric acute otitis media

OBJECTIVE

The 2004 American Academy of Pediatrics acute otitis media guidelines urge parents to weigh the benefits of reduced antibiotic use, adverse drug events, and future resistance versus risks of extra costs and sick days resulting from guideline use. The value of decreased antibiotic resistance has not been quantified. The objective was to perform cost-utility analysis, estimating the resistance value of implementing the guidelines for acute otitis media treatment for children <2 years of age. Outcomes were described with a common denominator and the value of avoiding resistance was estimated using a parental perspective.

METHODS

Decision analysis results were used for outcome probabilities. Published utilities were used to describe outcomes in quality-adjusted life-day units. The minimum resistance benefit value, where the benefits of the American Academy of Pediatrics guidelines would at least balance their costs, was defined as the guidelines' incremental costs minus their other benefits.

RESULTS

For a child 2 to <6 months of age presenting to a primary care physician with possible otitis media, parents would need to value the resistance benefit at 0.77 quality-adjusted life-days per antibiotic prescription avoided for the guidelines' benefits to balance their costs. For the 6- to <24-month-old group, results were 0.67 quality-adjusted life-days per prescription avoided. Results were sensitive to the dollar cost utility; when willingness to pay ranged from $20,000 to $200,000 per quality-adjusted life-year, results ranged from 0.36 and 0.30 quality-adjusted life-days up to 4.10 and 3.57 quality-adjusted life-days for the 2- to <6-month-old and 6- to <24-month-old groups, respectively. Costs were driven by missed parent work days.

CONCLUSIONS

From a societal perspective, trading 0.30 to 4 quality-adjusted life-days to avoid 1 antibiotic course might be desirable; from a parental perspective, this may not be as desirable. Parent demand for antibiotics may be rational when driven by the value of parent time. Other approaches that have the potential to reduce antibiotic use, such as wider use of influenza vaccine and improved rapid viral diagnostic techniques, might be more successful.
