Treatment of Acute Otitis Media in the Pediatric Emergency Department

Factors associated with inappropriateness of antibiotic prescriptions for acutely ill children presenting to ambulatory care in high-income countries: a systematic review and meta-analysis

BACKGROUND

Acutely ill children are at risk of unwarranted antibiotic prescribing. Data on the appropriateness of antibiotic prescriptions provide insights into potential tailored interventions to promote antibiotic stewardship.

OBJECTIVES

To examine factors associated with the inappropriateness of antibiotic prescriptions for acutely ill children presenting to ambulatory care in high-income countries.

METHODS

On 8 September 2022, we systematically searched articles published since 2002 in MEDLINE, Embase, CENTRAL, Web of Science, and grey literature databases. We included studies with acutely ill children presenting to ambulatory care settings in high-income countries reporting on the appropriateness of antibiotic prescriptions. The quality of the studies was evaluated using the Appraisal tool for Cross-Sectional Studies and the Newcastle-Ottawa Scale. Pooled ORs were calculated using random-effects models. Meta-regression, sensitivity and subgroup analysis were also performed.

RESULTS

We included 40 articles reporting on 30 different factors and their association with inappropriate antibiotic prescribing. 'Appropriateness' covered a wide range of definitions. The following factors were associated with increased inappropriate antibiotic prescribing: acute otitis media diagnosis [pooled OR (95% CI): 2.02 (0.54-7.48)], GP [pooled OR (95% CI) 1.38 (1.00-1.89)] and rural setting [pooled OR (95% CI) 1.47 (1.08-2.02)]. Older patient age and a respiratory tract infection diagnosis have a tendency to be positively associated with inappropriate antibiotic prescribing, but pooling of studies was not possible.

CONCLUSIONS

Prioritizing acute otitis media, GPs, rural areas, older children and respiratory tract infections within antimicrobial stewardship programmes plays a vital role in promoting responsible antibiotic prescribing. The implementation of a standardized definition of appropriateness is essential to evaluate such programmes.

Improving Emergency Department Use of Safety-Net Antibiotic Prescriptions for Acute Otitis Media

OBJECTIVES

Acute otitis media (AOM) is the most common reason for pediatric antibiotic prescriptions. The 2013 American Academy of Pediatrics' AOM guidelines recommend observation for nonsevere AOM. Our aim was to increase the percentage safety-net antibiotic prescription (SNAP) offered to patients 6 months of age or older diagnosed with AOM in 2 pediatric emergency departments (EDs) from a baseline of 0.5% to 15% in 20 months.

METHODS

This is a quality improvement study at a quaternary pediatric medical center with 2 locations, both with EDs. A random chart review revealed that 27.5% of patients diagnosed with AOM in the ED would qualify for a SNAP, but only 0.5% were offered it. Quality improvement interventions were designed to improve safety-net antibiotic prescribing. Both EDs conducted multiple interventions, including algorithm development, provider education, and electronic medical record aids. The primary outcome measure was the percentage of patients offered a SNAP for AOM.

RESULTS

A total of 8226 children 6 months of age or older were diagnosed with AOM in our 2 EDs during the 20-month intervention period. The percentage offered a SNAP increased at both EDs. One ED had a single shift in the mean to 7.9%, whereas the other had 2 shifts in the mean, an initial shift to 5.1% and a second to 7.3%. Providers consistently used the algorithm and electronic medical record aids.

CONCLUSIONS

Safety-net antibiotic prescriptions in conjunction with parent education was effective in reducing the use of immediate antibiotic prescriptions in children with AOM in 2 pediatric EDs. Offering a SNAP can reduce unnecessary use of antibiotics, which in turn may decrease antibiotic-related adverse events and antibiotic resistance.

Increasing Adherence to Acute Otitis Media Treatment Duration Guidelines using a Quality Improvement Approach

This quality improvement initiative aimed to improve American Academy of Pediatrics acute otitis media (AOM) guideline adherence in pediatric urgent care sites by increasing the percentage of patients 2 years and older with AOM who received a short duration (7 days or fewer) of antibiotics from a baseline of 7% to a goal of 50%.

METHODS

This quality improvement initiative was conducted in a network of seven urgent care sites affiliated with a large academic children's hospital. The interventions focused on clinician and family education, clinical decision support, and a discharge template that defaulted to a 7-day duration of antibiotics for patients 2 years and older diagnosed with AOM. The outcome measure was the percentage of patients receiving 7 days or fewer of antibiotics. The process measure was the percentage of prescriptions originating from the new discharge template. A repeat visit for AOM within 30 days from the initial visit was the balancing measure.

RESULTS

The percentage of patients diagnosed with AOM receiving a short antibiotic course increased from a baseline of 7% to a new centerline mean of 67%, which exceeded the goal. This project resulted in 10,138 antibiotic days being avoided. Eighty-two percent of short-course prescriptions originated from the discharge template. Repeat visits for AOM within 1 month of the initial visit did not increase.

CONCLUSIONS

A quality improvement initiative combining education and clinical decision support improved adherence to AOM treatment duration guidelines and avoided unnecessary antibiotic exposure in a pediatric urgent care network without increasing treatment failures.

Otolaryngologists, Pediatricians, and Emergency and Family Medicine Physicians Adherence to Acute Otitis Media Diagnosis and Management Guidelines: A Retrospective Study in a Saudi Arabian Tertiary Center

Background Acute otitis media (AOM) is one of the most common conditions in the pediatric population and a common reason for physicians to prescribe antibiotics. Most children will develop otitis media at least once during their life. Objectives Our study aimed to evaluate and compare the adherence of family medicine physicians, otolaryngologists, pediatricians, and emergency medicine physicians to the American Academy of Pediatrics and American Academy of Family Physicians guidelines for the diagnosis and the management of AOM. Methods This is a retrospective study that was conducted at the Ministry of National Guard - Health Affairs affiliated hospitals and primary clinics in Riyadh, Saudi Arabia. All patients diagnosed with AOM and treated between 2016 and 2019 were included in the study. Exclusion criteria included any patient above the age of 18 years old or patients with incomplete data on their files. Variables included demographic data of the patients and treating physicians, associated infections, and whether the treating physician followed the diagnosis and management guidelines. Results Most patients were below the age of two years. Emergency medicine physicians were the most common to treat patients with AOM. Although most documentations were sufficient, 39.8% were insufficient or not written. Most (74%) physicians adhered to the diagnosis guidelines, while 57.5% adhered to management guidelines. Conclusion Although most physicians adhered to the diagnosis and treatment guidelines, stressing on the matter is essential to avoid unnecessary antibiotics use. We recommend further prospective studies with a bigger sample size of more than one center to have a more accurate reflection of the current situation.

Antibiotic prescription policy for acute otitis media: do we follow the guidelines?

BACKGROUND

Acute otitis media (AOM) is a common cause for antibiotic prescription. Most guidelines endorse abstaining from immediate antibiotic treatment ('watchful waiting', WW) in mild-moderate episodes. We studied adherence rates to the latest AOM guidelines (2013), in terms of antibiotic type and prescription options.

METHODS

In this population-based study, AOM episodes were identified in Clalit Health Services-insured children aged 0-10 years between 2011 and 2018, using a data-sharing platform. After identifying the index, prescription and issuing dates for antibiotics for each AOM episode, treatment was categorized as immediate (≤2 days after diagnosis) or WW (antibiotic not prescribed/issued; prescribed ≤2 days after diagnosis but issued on Days 2-7; or prescribed/issued on Days 2-7). Guideline adherence was measured according to age.

RESULTS

Of the 491 106 episodes, 361 518 (73.6%) were treated with antibiotics. Following the 2013 guidelines, the ratio of episodes in children aged ≤6 months that were adherent (immediate treatment) was higher (OR = 1.22; 95% CI 1.15-1.29; P < 0.001), whereas the adherent episode ratio for children aged 6-24 months and 2-10 years (WW) was lower (OR = 0.87; 95% CI 0.85-0.88 and OR = 0.94; 95% CI 0.92-0.96, respectively; P < 0.001). Antibiotic prescription rates after 2013 for children aged ≤6 months were not different (OR = 1.03; 95% CI 0.96-1.1; P = 0.4), but were higher in children aged 6-24 months and 2-10 years (OR = 1.07; 95% CI 1.05-1.09; P < 0.001 and OR = 1.02; 95% CI 1.01-1.04; P = 0.015, respectively). Amoxicillin was the most common antibiotic, administered in 75.6% of episodes. Azithromycin was most commonly associated with treatment failure (6.6%).

CONCLUSIONS

Improved adherence to the 2013 guidelines was observed only in children aged ≤6 months and over-treatment with antibiotics was still high.

[Therapeutic approach to acute otitis media in primary care in an urban area. Delayed antibiotic prescription evaluation]

BACKGROUND AND OBJECTIVES

Acute otitis media (AOM) is one of the most frequent causes of consultation and antibiotic prescription in pediatrics. The objective of this work is to evaluate the practice of delayed antibiotic prescription in AOM in pediatrics primary care.

MATERIAL AND METHODS

Observational, retrospective study, through reviewing of medical records in a primary care center of Aragon Community of children with OMA in which doctors perform delayed prescription. Logistic regression analyzes possibly related to antibiotic prescription factors.

RESULTS

1,390 episodes of AOM are analyzed in 696 patients. Immediate antibiotic prescription is performed in 67.6% (95% CI 65.1-70.0) of episodes, exclusive symptomatic in 13.7% (95% CI 11.9-15.6), and delayed antibiotic in 18.7% (95% CI 16.7-20.8), finally being given in 53.5% (95% CI 47.4-59.5) of these. Factors significantly related to final antimicrobial dispensation in delayed prescription are aged between 0 and 2 years (OR 1.89, 95% CI 1.25-2.87), bilaterality (OR 2.54, 95% CI 1.48-4.35), ear pain (OR 0.49, 95% CI 0.29-0.82), fever (OR 2.67, 95% CI 1.95-3.65), bulging (OR 3.63, 95% CI 2.50-5.29) and otorrhea (OR 25.98, 95% CI 12.75-52.92). The same factors have influence on global prescription of antibiotics. Amoxicillin (74.6%) is the most indicated antibiotic, followed by amoxicillin-clavulanic (17.0%).

CONCLUSIONS

Delayed prescription in AOM seems to be useful to reduce antibiotics consumption, being necessary to advance in its implantation.

Inpatient Treatment of Acute Otitis Media at a Pediatric Hospital: A Missed Teaching Opportunity for Antimicrobial Stewardship

BACKGROUND

Acute otitis media (AOM) is a common pediatric condition known to contribute to excessive antibiotic use in the outpatient setting. Treatment of AOM in the inpatient setting has not been described. The objective was to describe the clinical features and inpatient management of AOM to harness this entity to teach learners about judicious antibiotic prescribing in all settings.

METHODS

This is a single-center retrospective cohort study of inpatients treated for AOM from January 2015 to December 2018. Patients were included if they had an antibiotic ordered and either a provider-selected order indication of otitis media or an International Classification of Diseases, 10th Revision billing code of AOM. A chart review was performed to identify primary diagnoses, examination features, and treatment, including excess days of therapy.

RESULTS

We included 840 hospitalized patients treated for AOM in this study. At least 71% of patients had a concurrent viral respiratory illness. Examinations were frequently discordant (34%), and 47% lacked documentation of a physical examination finding of a bulging tympanic membrane, contributing to 3417 potential excess days of therapy. Of the total patients treated for AOM, 40% were given excess duration of therapy. The vast majority (97%) of patients who qualified for a wait-and-watch approach were treated.

CONCLUSIONS

AOM is not being rigorously diagnosed or treated in a guideline-adherent manner in the inpatient setting. This is a lost opportunity for teaching antibiotic stewardship. Interventions, such as promoting the wait-and-watch approach and deferring treatment decisions to inpatient providers, could help promote the judicious use of antibiotics.

Assessing the appropriateness of the management of otitis media in Australia: A population-based sample survey

AIM

Acute otitis media (AOM) is the most common infectious disease for which antibiotics are prescribed; its management is costly and has the potential to increase the antimicrobial resistance of this infection. This study measured the levels of adherence to the clinical practice guidelines (CPGs) of AOM and otitis media with effusion (OME) management in Australian children.

METHODS

We searched for national and international CPGs relating to AOM and OME in children and created 37 indicators for assessment. We reviewed medical records for adherence to these indicators in 120 locations, across one inpatient and three ambulatory health-care settings. Our review sample was obtained from three Australian states that contain 60% of the nation's children.

RESULTS

We reviewed the records of 1063 children with one or more assessments of CPG adherence for otitis media. Of 22 indicators with sufficient data, estimated adherence ranged from 7.4 to 99.1%. Overuse of treatment, particularly overprescribing of antibiotics, was more common than underuse. A frequent lack of adherence with recommended care was observed for children aged between 1 and 2 years with AOM. Adherence varied by health-care setting, with emergency departments and inpatient settings more adherent to CPGs than general practices.

CONCLUSIONS

Our assessment of a number of indicators in the common settings in which otitis media is treated found that guideline adherence varied widely between individual indicators. Internationally agreed standards for diagnosis and treatment, coupled with clinician education on the existence and content of CPGs and clinical decision support, are needed to improve the management of children presenting with AOM and OME.

Updated Guidelines for the Management of Acute Otitis Media in Children by the Italian Society of Pediatrics: Treatment

BACKGROUND

New insights into the diagnosis, treatment and prevention of acute otitis media (AOM) have been gained in recent years. For this reason, the Italian Paediatric Society has updated its 2010 guidelines.

METHODS

A literature search was carried out on PubMed. Only pediatric studies published between January 1, 2010 and December 31, 2018 in English or Italian were included. Each included study was assessed according to the GRADE methodology. The quality of the systematic reviews was assessed using AMSTAR 2. The recommendations were formulated by a multidisciplinary panel of experts.

RESULTS

Prompt antibiotic treatment is recommended for children with otorrhea, intracranial complications and/or a history of recurrence and for children under the age of 6 months. For children 6 months to 2 years of age, prompt antibiotic treatment is recommended for all forms of unilateral and bilateral AOM, whether mild or severe. Prompt antibiotic treatment is also recommended for children over 2 years with severe bilateral AOM. A watchful-waiting approach can be applied to children over 2 years with mild or severe unilateral AOM or mild bilateral AOM. High doses of amoxicillin, or amoxicillin-clavulanic acid for patients with a high risk of infection by Beta-lactamase producing strains, remain the first-line antibiotics.

CONCLUSIONS

AOM should be managed on a case-by-case basis that takes account of the child's age, the severity of the episode and whether it is unilateral or bilateral. In patients under 2 years, prompt antibiotic treatment is always recommended.
