ObjectiveTo systematically assess the diagnostic accuracy of rapid point-of-care tests for diagnosis of current SARS-CoV-2 infections in children under real-life conditions.DesignSystematic review and meta-analysis.Data sourcesMEDLINE, Embase, Cochrane Database for Systematic Reviews, INAHTA HTA database, preprint servers (via Europe PMC), ClinicalTrials.gov, WHO ICTRP from 1 January 2020 to 7 May 2021; NICE Evidence Search, NICE Guidance, FIND Website from 1 January 2020 to 24 May 2021.Review methodsDiagnostic cross-sectional or cohort studies were eligible for inclusion if they had paediatric study participants and compared rapid point-of care tests for diagnosing current SARS-CoV-2 infections with reverse transcription polymerase chain reaction (RT-PCR) as the reference standard. The Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool was used to assess the risk of bias and the applicability of the included studies. Bivariate meta-analyses with random effects were performed. Variability was assessed by subgroup analyses.Results17 studies with a total of 6355 paediatric study participants were included. All studies compared antigen tests against RT-PCR. Overall, studies evaluated eight antigen tests from six different brands. Only one study was at low risk of bias. The pooled overall diagnostic sensitivity and specificity in paediatric populations was 64.2% (95% CI 57.4% to 70.5%) and 99.1% (95% CI 98.2% to 99.5%), respectively. In symptomatic children, the pooled diagnostic sensitivity was 71.8% (95% CI 63.6% to 78.8%) and the pooled diagnostic specificity was 98.7% (95% CI 96.6% to 99.5%). The pooled diagnostic sensitivity in asymptomatic children was 56.2% (95% CI 47.6% to 64.4%) and the pooled diagnostic specificity was 98.6% (95% CI 97.3% to 99.3%).ConclusionsThe performance of current antigen tests in paediatric populations under real-life conditions varies broadly. Relevant data were only identified for very few antigen tests on the market, and the risk of bias was mostly unclear due to poor reporting. Additionally, the most common uses of these tests in children (eg, self-testing in schools or parents testing their toddlers before kindergarten) have not been addressed in clinical performance studies yet. The observed low diagnostic sensitivity may impact the planned purpose of the broad implementation of testing programmes.PROSPERO registration numberCRD42021236313.
Surgeons should develop a structured multidisciplinary approach to innovation management in their hospitals before using a new high-risk device. The key question is how to strike the right balance between innovation and safety.
Objective: To systematically assess the diagnostic accuracy of rapid point-of-care tests for diagnosis of current SARS-CoV-2 infections in children under real-life conditions. Study design: Multiple bibliographic databases including MEDLINE and Embase, clinical trial registries and further information sources were systematically searched for literature (last bibliographic search: May 7, 2021). Diagnostic cross-sectional or cohort studies that included paediatric study participants and evaluated rapid point-of care tests for diagnosing current SARS-CoV-2 infections against RT-PCR as the reference standard were eligible for inclusion. QUADAS-2 was used to assess the risk of bias and the applicability of the included studies. Bivariate meta-analyses with random effects were performed. Variability was assessed by subgroup analyses. Results: We included 17 studies with a total of 6355 paediatric study participants. All included studies compared antigen tests against RT-PCR. Only one study was at low risk of bias. The pooled overall diagnostic sensitivity and specificity in paediatric populations was 64.2% (95% CI: 57.4%-70.5%) and 99.1% (95% CI: 98.2%-99.5%), respectively. In symptomatic children, the pooled diagnostic sensitivity was 71.8% (95% CI: 63.6%-78.8%) and the pooled diagnostic specificity was 98.7% (95% CI: 96.6%-99.5%). The pooled diagnostic sensitivity in asymptomatic children was 56.2% (95% CI: 47.6%-64.4%) and the pooled diagnostic specificity was 98.6% (95% CI: 97.3%-99.3%). Conclusions: Performance of current antigen tests under real-life conditions varies broadly. Policymakers should especially be aware of the low diagnostic sensitivity of current antigen tests. Results should be interpreted with caution since risk of bias was predominantly judged as unclear due to poor reporting. Study Registration: CRD42021236313 (PROSPERO).
HTA can have a significant impact on the provision of health services, but various loopholes allow physicians to undermine policy decisions. Therefore, it is important to involve all stakeholders in HTA and to convince them of the benefits of evidence-based medicine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
