Detailed Description

Tympanostomy tube placement (TTP) for recurrent acute otitis media (rAOM) is frequently performed in children under 3 years of age; however, a critical need exists to establish its risk/benefit ratio. Seventy percent of children experience at least one episode of AOM during the first year of life; 20% of children have rAOM. The efficacy of TTP for preventing rAOM, assumedly by maintaining middle-ear ventilation, remains unclear. Benefits of TTP must be balanced against risks of anesthesia, complications and sequelae of surgery, and cost. Accordingly, the objective of this proposal is to determine the efficacy of TTP in children aged 6-35 months, the group in which rAOM is most troublesome. The central hypothesis is that in children with rAOM, the operation will prove effective over the ensuing 2 years overall, but the benefit in a more severely affected, and therefore higher-risk subgroup may be substantially greater than in a less severely affected subgroup, in whom benefits may not outweigh risks. The rationale for this research is based on a belief that the limited nature of the benefit of TTP found in earlier clinical trials may have been the result of enrolling children whose illnesses had not been diagnosed using stringent criteria and/or whose ascertainment of episodes had relied on undocumented histories. The primary objective is to determine the extent to which TTP reduces the overall rate of recurrences in children with rAOM over a 2-year period. In a randomized, clinical trial, children aged 6-35 months who are at risk for rAOM will be followed prospectively and examined promptly with new respiratory illnesses to accurately document episodes of AOM. A total of 240 children who meet stringent inclusion criteria for rAOM will be eligible to undergo randomization within strata (age and exposure to other children) to receive TTP or nonsurgical management. Children will be followed for 2 years; the average number of episodes of AOM will be documented and compared between groups. The secondary objective is to determine changes following TTP in nasopharyngeal (NP) colonization with resistant bacteria. At the time of randomization and 3 times a year for 2 years, NP specimens will be obtained and cultured. Susceptibility testing and serotyping will be performed, and the proportions of children colonized with resistant bacteria compared between treatment groups. The tertiary objective is to determine cost-effectiveness of TTP. The investigators will calculate both direct medical and nonmedical costs and correlate this with the number of days that each child has AOM symptoms, otorrhea, and any adverse events or complications. The proposed research is innovative, as the investigators will document AOM episodes prospectively using stringent diagnostic criteria and obtain digital tympanic membrane images otoendoscopically to enhance accuracy of observations. Findings of the proposed study will provide clinicians and parents with dependable evidence concerning the overall effects of TTP compared with nonsurgical management in children with rAOM of varying degrees of severity, enabling evidence-based decisions regarding an important component of the children's healthcare.

Active Comparator: Surgical Management
Tympanostomy Tube Placement Topical antimicrobial treatment of acute otitis media episodes with ofloxacin drops
Device: Tympanostomy tube placement
As per routine care, tympanostomy tubes will be inserted under general anesthesia, using a small radial incision in the anteroinferior portion of the tympanic membrane; a Teflon® Armstrong-type tympanostomy tube will be used.
Drug: Ofloxacin Otic
Participants randomized to receive tympanostomy tubes will also be followed overtime for recurrences of AOM and treated with topical ofloxacin (Floxin® 0.3%, 5 mL) 5 drops into the affected ear twice daily for 10 days. Persistence of otorrhea after 7 days of treatment will be considered inadequate response, and children so affected will be prescribed empiric amoxicillin-clavulanate (90/6.4 mg/kg/day in two divided doses) followed by culture-directed therapy 48 hours later.
Other: Non-Surgical Management
Antimicrobial treatment of acute otitis media episodes with amoxicillin-clavulanate and/or ceftriaxone
Drug: Amoxicillin-Clavulanate and/or Ceftriaxone
Children randomized to nonsurgical management will receive stepwise therapy with amoxicillin-clavulanate (90/6.4 mg/kg in two divided doses for 10 days), and in the event of inadequate response, ceftriaxone (75 mg/kg intramuscularly, repeated in 48 hours), as recommended in the American Academy of Pediatrics guidelines.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Rate of Occurrence of Acute Otitis Media (AOM) Episodes Per Child-Year
Time Frame: Day 1 until Day 786. The mean length of actual follow-up was 662 days / 1.8 years. For each child with incomplete 2-year follow-up, multiple imputation was used and values for the remaining days/years were imputed.
An episode of AOM is considered a discrete occurrence if symptoms and signs persisted for, or recurred, 17 or more days after the start of antimicrobial treatment. The rate is calculated by dividing the total number of occurrences by the total number of years of follow-up. Multiple imputation was used when follow-up was incomplete.
Day 1 until Day 786. The mean length of actual follow-up was 662 days / 1.8 years. For each child with incomplete 2-year follow-up, multiple imputation was used and values for the remaining days/years were imputed.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The Rate of Occurrence of Acute Otitis Media (AOM) Episodes Per Child-Year According to the Estimated Risk of Acute Otitis Media (AOM) Recurrences at Enrollment
Time Frame: Day 1 until Day 786. The mean length of actual follow-up was 662 days / 1.8 years. For each child with incomplete 2-year follow-up, multiple imputation was used and values for the remaining days/years were imputed.
An episode of AOM is considered a discrete occurrence if symptoms and signs persisted for, or recurred, >=17 days after the start of antimicrobial treatment. The rate is calculated by dividing the total # of occurrences by the total # of years of follow-up. Risk of recurrences was based on early age of onset of AOM; numerous and/or frequent previous AOM episodes; receipt of multiple courses of antibiotic; eligibility for enrollment first evident during warm-weather months; parental characterization of previous AOM episodes as severe; eligibility for enrollment despite nonexposure to other young children; moderate or marked tympanic membrane (TM) bulging with previous AOM episodes; most previous AOM episodes in both ears; and a high score on the Acute Otitis Media Severity of Symptom scale (with scores ranging from 0 to 10 and higher scores indicating greater severity of symptoms) during screening and/or at enrollment. Multiple imputation was used when follow-up was incomplete.
Day 1 until Day 786. The mean length of actual follow-up was 662 days / 1.8 years. For each child with incomplete 2-year follow-up, multiple imputation was used and values for the remaining days/years were imputed.
The Frequency Distribution of AOM Episodes Among Children Completing the Study
Time Frame: Day 1 until Day 786. For children completing the study, the mean length of follow-up was 726 days.
An episode of AOM is considered a discrete occurrence if symptoms and signs persisted for, or recurred, 17 or more days after the start of antimicrobial treatment. Children with at least 23 months of follow-up were considered to have completed the study.
Day 1 until Day 786. For children completing the study, the mean length of follow-up was 726 days.
The Distribution of Children Experiencing Treatment Failure (TF)
Time Frame: Day 1 until Day 786.
Parents used the Acute Otitis Media Severity of Symptoms (AOM-SOS) scale (version 4.0) to rate each of 5 symptoms as none, a little, or a lot, with corresponding scores of 0, 1, and 2. Total scores range from 0 to 10; higher scores indicate greater severity of symptoms. AOM episodes were categorized as likely severe if the parent described the child as having moderate or severe otalgia (a lot of ear tugging), temperature ≥39°C, or an AOM-SOS scale score >6 Day 1 of the episode. TF is defined as frequent AOM recurrences (2 in 3 months, 3 in 6 or 4 in 12); ≥3 likely severe AOM recurrences, receipt of ≥45 cumulative days of systemic antimicrobial treatment for AOM, otorrhea for ≥45 cumulative days or diarrhea associated with antimicrobial treatment for ≥30 cumulative days, respectively, in 12 months; persistent effusion for ≥12 successive months; TM perforation for ≥90 days; AOM related hospitalization; anesthesia reactions; and tubes in children randomized to nonsurgical management.
Day 1 until Day 786.
The Time to the First Episode of AOM
Time Frame: Day 1 until Day 786. The mean length of follow-up was 662 days / 21.8 months.
The time to the first episode of AOM is defined as the time, expressed in months, from randomization until the first episode of AOM.
Day 1 until Day 786. The mean length of follow-up was 662 days / 21.8 months.
The Distribution of AOM Episodes Categorized as Probably Severe or Probably Nonsevere
Time Frame: Day 1 until Day 786.
The American Academy of Pediatrics clinical practice guideline concerning the management of AOM refers to children with "severe signs or symptoms" as those with "moderate or severe otalgia or otalgia for >= 48 hours or temperature 39°C (102.2°F) or higher." To simulate that definition, scores are used from the 5-item Acute Otitis Media Severity of Symptoms (AOM-SOS) scale (version 4.0) in which parents are asked to rate symptoms, as compared with the child's usual state, as none, a little, or a lot, with corresponding scores of 0, 1, and 2. Total scores range from 0 to 10, with higher scores indicating greater severity of symptoms. AOM episodes are categorized as "probably severe" if the parent described the child as having had moderate or severe otalgia (a lot of ear tugging; i.e. a score of 2), temperature >=39°C, or an AOM-SOS scale score >6 on Day 1 of the episode. If not "probably severe", then the episode is categorized as "probably nonsevere".
Day 1 until Day 786.
The Distribution of AOM Episodes Presenting With Tympanic Membrane Bulging or Otorrhea
Time Frame: Day 1 until Day 786.
The presence of either tympanic membrane bulging or tympanic membrane perforation with purulent otorrhea, in addition to documentation of symptoms, is required for each episode of AOM.
Day 1 until Day 786.
The Mean Days Per Year Children Experience Tube Otorrhea
Time Frame: Day 1 until Day 786. The mean length of follow-up was 662 days / 1.8 years.
Adverse events, including tube-associated otorrhea, were collected from enrollment through the end of study. Each study visit included a review of adverse events. Any such event that occurred since the previous visit was recorded, including the date of onset and the date of resolution. For each child, the days per year of tube otorrhea is calculated by dividing the total number of days of tube otorrhea (based on dates of onset and resolution) by the total number of years of follow-up.
Day 1 until Day 786. The mean length of follow-up was 662 days / 1.8 years.
The Mean Days Per Year Children Experience AOM Symptoms With an Intact Tympanic Membrane (TM)
Time Frame: Day 1 until Day 786. The mean length of follow-up was 662 days / 1.8 years.
For a given child, if a day of follow-up coincides with a study visit, the status of the right and left TMs are recorded at the ear exam. If a day of follow-up does not coincide with a study visit the status of each TM is assumed to be the same as the status on the prior day. Scores are used from the 5-item Acute Otitis Media Severity of Symptoms (AOM-SOS) scale (version 4.0) in which parents are asked to rate symptoms, as compared with the child's usual state, as none, a little, or a lot, with corresponding scores of 0, 1, and 2. Total scores range from 0 to 10, with higher scores indicating greater severity of symptoms. Scores are recorded at study visits and on diaries. The total number of days with an intact TM and a AOM-SOS score greater than or equal to 1 is divided by the total number of years of follow-up to arrive at the days per year with AOM symptoms and an intact TM.
Day 1 until Day 786. The mean length of follow-up was 662 days / 1.8 years.
The Mean Days Per Year Children Receive Systemic Antimicrobials for AOM
Time Frame: Day 1 until Day 786. The mean length of follow-up was 662 days / 1.8 years.
Systemic antibiotics include Amoxicillin-Clavulanate, Ceftriaxone, Cefdinir, Amoxicillin, Azithromycin, Clindamycin, Levofloxacin, Bactrim, Cefprozil, Omnicef and Trimethoprim-Sulfamethoxazole. The days per year, for each child, is calculated by dividing the total number of days the child receives systemic antimicrobials for AOM (based on the recorded start and stop dates) by the total number of years of follow-up.
Day 1 until Day 786. The mean length of follow-up was 662 days / 1.8 years.

The Mean Scores on the 6 Item Quality of Life Survey Questionnaire (OM-6)
Time Frame: Day 1 until Day 786.
The OM-6 is a 6 item quality of life assessment addressing physical suffering, hearing loss, speech impairment, emotional distress, activity limitations and caregiver concerns. Responses are regarded on an ordinal scale ranging from 1 (no problem) to 7 (greatest problem). The average response, i.e., score, for these 6 items is calculated. The overall child's quality of life (QOL) score, also captured on the OM-6, is expressed on an ordinal response scale that ranges from 0 (worst quality of life) to 10 (best quality). A OM-6 is administered to the parent every 16 weeks after randomization and occasionally at sick visits.
Day 1 until Day 786.
The Mean Scores on the 6 Item Caregiver Impact Questionnaire (CIQ)
Time Frame: Day 1 until Day 786.
The Caregiver Impact Questionnaire (CIQ) is a 6 item assessment addressing lack of sleep, absence from work or education, canceling of family activities, changing daily activities, feeling nervous and feeling helpless. Each of these responses is expanded to a continuous scale from 0 (no impact on caregiver) to 100 (greatest impact). The average response, i.e., score, for these 6 items is calculated. The overall caregiver's quality of life (QOL) score, also captured on the CIQ, is expressed on a ordinal response scale that ranges from 0 (worst quality of life) to 10 (best quality). The CIQ is administered to the parent every 16 weeks after randomization and occasionally at sick visits.
