The Cochrane protocol differed from the committee&#x02019;s intended population in that the Cochrane protocols excluded studies that did not meet their inclusion criteria for trustworthiness (that is, those identified as being potentially &#x02018;high-risk&#x02019; using a screening tool developed by Cochrane Pregnancy and Childbirth which included specified criteria to identify studies that are considered sufficiently trustworthy), however no studies were identified that were excluded from the review on these grounds alone.</p><p>The Cochrane review team completed a review investigating the effectiveness of steroids for OME in children (<a class="bibr" href="#niceng233er8.s1.ref1" rid="niceng233er8.s1.ref1">Mulvaney 2023b</a>) during guideline development and presented their results to the committee, who used them to make recommendations. Cochrane&#x02019;s methods are closely aligned to standard NICE methods; minor deviations (summary of findings tables instead of full GRADE tables, defining primary and secondary outcomes as opposed to critical and important, assessing the risk of bias in primary studies using version 1 (as opposed to version 2) of the Cochrane Risk of Bias tool, how clinically important differences are determined, and including countries from a broader range of income categories than the majority of the other reviews in the guideline) relevant to the topic area were highlighted to the committee and taken into account in discussions of the evidence. Where results were reported per ear instead of per child, Cochrane used an assumed intra-cluster correlation coefficient of 0.5 to adjust the sample size. Full details of the Cochrane review, including methods, are available in the review of steroids for children with OME, see <a class="bibr" href="#niceng233er8.s1.ref1" rid="niceng233er8.s1.ref1">Mulvaney 2023b</a> at <a href="https://www.nice.org.uk/guidance/indevelopment/gid-ng10193/documents" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">https://www.nice.org.uk/guidance/indevelopment/gid-ng10193/documents</a>.</p><p>We thank the Cochrane ENT Group for their assistance in providing the literature searches and data for review questions relating to Otitis media with effusion in under 12s.</p></div><div id="niceng233er8.s1.1.3.2"><h5>Antihistamines, leukotriene receptor antagonists, mucolytics and decongestants</h5><p>The parts of the evidence review on the effectiveness of antihistamines, leukotriene receptor antagonists, mucolytics and decongestants was developed using the methods and process described in <a href="https://www.nice.org.uk/process/pmg20/chapter/introduction" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">Developing NICE guidelines: the manual</a>.

Oral steroids had an important benefit for persistence of OME in the very short term (very low quality evidence according to GRADE criteria), but no important difference between oral steroids and no treatment for persistence of OME in the short or medium term (both low quality evidence according to GRADE criteria).

Oral steroids had an important benefit for persistence of OME in the medium term when persistence was undefined (low quality evidence according to GRADE criteria), and a possible important benefit for persistence of OME in the very short term (90% CI: 0.54 to 0.96; very low quality).

The committee agreed these outcomes were critical: hearing is a direct measure of any differential effectiveness associated with the use of medication; disease-specific quality of life is a measure of well-being which may capture long-term health-related outcomes associated with the effectiveness of interventions; discontinuation of treatment would capture both potential benefits and risks of the intervention depending on the reason for discontinuation of treatment (for example, because they no longer need the medication, or because the child could not tolerate the medication); systemic corticosteroid side-effects would capture the risk of adverse events (such as muscle weakness) which can happen as a result of the use of oral steroids. The primary outcomes for the review on antihistamines, leukotriene receptor antagonists, mucolytics and decongestants were similar to those for the Cochrane review on steroids; however, presence/ persistence of OME was chosen as a primary outcome instead of disease-specific quality of life, which was a secondary outcome for this review. The committee agreed that presence or persistence of OME after the use of medication directly measures the effectiveness of the intervention whereas quality of life is a less direct measure with other influences and arguably a greater subjective element. Therefore, presence of OME was kept as a primary outcome for internal consistency with other reviews conducted for this guideline, however Cochrane kept it as a secondary outcome to be consistent with their previous reviews.</p><p>The other outcomes listed in the Cochrane protocol (presence/ persistence of OME; receptive language skills; listening skills) were agreed to be important outcomes by the committee. The committee agreed that OME-related hearing loss can be associated with impairment of receptive language and listening skills, which could impact on the child&#x02019;s development, and therefore the committee agreed these were important outcomes. The review on antihistamines, leukotriene receptor antagonists, mucolytics and decongestants also had receptive language and listening skills as secondary outcomes.</p></div><div id="niceng233er8.s1.1.10.2"><h5>The quality of the evidence</h5><div id="niceng233er8.s1.1.10.2.1"><h5>Steroids</h5><p>The quality of the evidence was assessed using GRADE methodology and was moderate to very low quality, mainly due to risk of bias assessed using version 1 of the Cochrane RoB tool and imprecision in the effect estimate. Where outcomes were downgraded for risk of bias, this was mainly due to selection, performance, attrition, reporting and/ or detection bias. In some cases, there was also bias arising from the randomisation process and/or measurement of the outcomes.

Where outcomes were downgraded for risk of bias, this was mainly due to deviations from the intended interventions, missing outcome data, and/or selection of the reported result. In some cases, there was also bias arising from the randomisation process and/or measurement of the outcomes. For some outcomes, there was additionally indirectness due to the inclusion of an indirect population, outcome, or intervention, and/or suspected publication bias due to the majority of studies contributing to the outcome being industry funded.</p><p>There was no evidence available for proton pump inhibitors (PPIs) and reflux medicines, and no evidence for any of the secondary outcomes (listening skills, receptive language skills measured using a validated scale, or disease-specific quality of life measured using a validated scale).

Additionally, the committee discussed the fact that oral steroids often have a stronger effect that nasal steroids. Considering the moderate quality evidence that oral steroids made no difference in terms of the above outcomes when compared to placebo and the limited, low quality evidence when compared to no treatment, the committee agreed that it was unlikely that nasal steroids, which usually have a weaker effect, would have an important hearing-, OME-, or quality of life-related benefit either. They agreed this reasoning outweighed the low to very low quality evidence that nasal steroids had an important benefit when compared to not treatment or placebo with regards to final hearing thresholds in the short term, persistence of OME in the very short, short, and (when persistence was undefined in the evidence) medium term, and generic health-related quality of life in the medium term. There was some limited evidence that oral steroids had an important benefit in terms of persistence of OME in the medium term (when persistence was undefined in the evidence) compared to no treatment, and a possible important benefit in terms of persistence of OME in the very short term. However, where there was evidence of a clinically important effect of oral steroids for any of the outcomes, the evidence was all low or very low quality, or there was uncertainty in the importance of the outcome. The committee agreed the evidence was not strong enough to recommend oral steroids when there was the potential for children to experience systemic corticosteroid side effects, especially in light of the lack of available evidence for this outcome. The committee also discussed the potential harms of using nasal steroids and agreed that, although the risks of side effects was lower than for oral steroids, nasal steroids can be difficult to administer, particularly for very young children or children with learning difficulties or other disabilities. They agreed that using nasal drops or spray could be traumatic for children and ultimately agreed the very low quality evidence showing a potential benefit on hearing or persistence of OME did not outweigh these harms. As a result, the committee recommended that nasal and oral steroids should not be used to treat OME in children.</p><p>The committee agreed the evidence base regarding the effectiveness of topical nasal steroids in the management of OME was limited and tended to focus on the outcome persistence of OME. It is therefore not clear if these are effective for improving the hearing of children with OME, and the committee agreed a research recommendation investigating the effectiveness of topical nasal steroids on OME-related hearing loss should be made, as this intervention could be a low-cost, readily accessible management option that might be preferable to other, more invasive interventions such as surgery.</p></div><div id="niceng233er8.s1.1.10.3.2"><h5>Antihistamines, leukotriene receptor antagonists, mucolytics and decongestants</h5><p>The committee agreed that the evidence tended to show no important difference in effectiveness of antihistamines, leukotriene receptor antagonists, mucolytics, and decongestants, whether alone or in combination, for most of the outcomes when compared to any of the comparison arms. Where there was evidence of a difference between treatment groups, the evidence was of low or very low quality or there was uncertainty in the importance of the outcome, whereas all the available moderate quality evidence showed no important difference between groups. As a result, the committee agreed that these medications should not be offered to treat OME in children under 12. The committee agreed they could not make recommendations about PPIs or other reflux medicines without any evidence regarding their effectiveness, because PPIs and reflux medicines are not routinely offered to children with OME in current practice, and it is unclear whether they would be effective for treating OME or OME-related hearing loss.</p><p>Although the committee agreed antihistamines, leukotriene receptor antagonists, mucolytics, and decongestants should not be offered based on the current evidence, the committee members agreed that further research into the effectiveness of these interventions in children with OME and chronic respiratory conditions is important as there might be benefit for this subgroup, based on the evidence of risk factors and respiratory conditions that are commonly associated with OME, for which these medications might be effective.</p></div></div><div id="niceng233er8.s1.1.10.4"><h5>Cost effectiveness and resource use</h5><p>Two included studies (<a class="bibr" href="#niceng233er8.s1.ref27" rid="niceng233er8.s1.ref27">Williamson 2009</a>; <a class="bibr" href="#niceng233er8.s1.ref28" rid="niceng233er8.s1.ref28">Francis 2018</a>) reported on the cost-effectiveness of intranasal and oral steroids respectively. Neither study found steroids to be cost-effective with placebo dominating intervention in the base case utility analyses. Whilst differences in costs and effects were not statistically significant, probabilistic sensitivity analysis suggested that there was only a relatively small probability that giving steroids was cost-effective. Therefore, the committee concluded there was no cost-effectiveness evidence that would support a recommendation to give steroids.</p><p>The committee also concluded that it would not be a cost-effective use of NHS resources to recommend other non-antimicrobial pharmacological treatments for OME given the lack of evidence of clinical benefit in the studies reviewed.</p></div></div><div id="niceng233er8.s1.1.11"><h4>Recommendations supported by this evidence review</h4><p>This evidence review supports recommendations 1.5.3 and 1.5.4, the research recommendation on the effectiveness of topical nasal steroids on OME and OME-related hearing loss in children under 12 years, and the research recommendation on the effectiveness of antihistamines, leukotriene receptor antagonists, mucolytics, PPIs and decongestants on hearing in children with OME and chronic respiratory conditions.</p></div></div><div id="niceng233er8.s1.rl.r1"><h3>References &#x02013; included studies</h3><ul class="simple-list"><div id="niceng233er8.s1.rl.r1.1"><h4>Effectiveness</h4><ul class="simple-list"><div id="niceng233er8.s1.rl.r1.1.1"><h5>Steroids</h5><ul class="simple-list"><li class="half_rhythm"><p><div class="bk_ref" id="niceng233er8.s1.ref1"><p id="p-659">

<p>Diagnostic criteria for OME at baseline were the presence of visible middle ear fluid and/ or impaired mobility of the tympanic membrane on pneumatic otoscopy, and a type B, C, or A(s) tympanogram (only type A tympanograms were considered normal).</p>
<p>At follow-up, clinical (otoscopic) criteria are the same as at baseline (presence of visible middle ear fluid and/ or impaired mobility of the tympanic membrane on pneumatic otoscopy). However, for tympanometry, both type A and A(s) tympanograms were considered normal at follow-up and therefore reported as resolution of OME, which was different to the tympanometry diagnostic criteria used at baseline.</p>
