SBU Evidence map
systematically evaluates the quality of systematic reviews in a particular field for the purpose of identifying reliable evidence and gaps in scientific knowledge. SBU Evidence Maps are generated with the help of experts in the field. Prior to publication, maps are examined by independent experts, as well as our quality and priority group and SBU’s Scientific Advisory Committees.
The aim of this report is to identify all systematic reviews with low or moderate risk of bias on drug treatments for children with respiratory tract infections, to systematically and transparently describe the extent of research in the field, and to identify gaps in the research base.
What does this evidence map add?
The result from this scoping review demonstrates that a large number of treatments given to children have not been evaluated in any systematic review of low or moderate risk of bias. This report is a summary of existing systematic reviews in the field and should not be used as treatment guidelines.
Respiratory tract infections are the most common infections seen in school-aged children, with 7 to 10 infections a year being considered normal. Most respiratory tract infections are caused by viruses and heal without any treatment. However, antibiotic treatments are prescribed to children between the ages of one and seven with respiratory tract infections more often than to older children and adults. Fever and other symptoms associated with respiratory tract infections are also more commonly treated with medication in children aged 1–7. This report was initiated by the Medical Products Agency after consulting professional organizations in this field.
A mapping of systematic reviews to domains considered important by pediatricians in their daily clinical practices was undertaken (see table below). After searching several electronic databases for systematic reviews relevant to the identified domains, two reviewers independently screened the abstracts for relevance. Identified full text reviews were then assessed independently by two reviewers for relevance and thereafter methodological quality using AMSTAR. Differences were resolved by consensus. Systematic reviews judged to have low or moderate risk of bias were then used to assess the current body of evidence, including identifying those domains where insufficient evidence is available.
Out of the 165 systematic reviews meeting the inclusion criteria, 72 were judged to have a low or moderate risk of bias. Within the body of evidence we found evidence to support practice in some of the identified pediatric healthcare domains. However, no systematic reviews with low or moderate risk of bias were identified assessing the treatment of throat abscesses, mastoiditis, epiglottitis or tracheitis.
