We looked at existing recommendations and supporting evidence on the effectiveness of universal screening for language and speech delay in children under 5 years of age for short- and long-term outcomes.We conducted a literature search up to the 20th of November 2019 by using key terms and manual search in selected sources. We summarized the recommendations and the strength of the recommendation when and as reported by the authors. We summarized the main findings of systematic reviews with the certainty of the evidence as reported on the accuracy of the screening tests for detecting language and speech delay, the efficacy of existing interventions for children with language and speech delay, and the potential harms associated with screening and the associated interventions.Several screening tools are used to assess language and speech delay with a wide variation in their accuracy. Targeted interventions improve some measures of speech and language delay and disorders. However, there is no evidence on the effectiveness of such interventions in children detected by screening with no specific concerns about their speech or language before screening. There is no evidence assessing whether universal screening for language and speech delay in a primary care setting improves short and long-term outcomes (including speech and language outcomes and other outcomes). Finally, there is no evidence on the harms of screening for language and speech delay in primary care settings, and there is limited evidence assessing the potential harms of interventions.
我们研究了现有的关于对 5 岁以下儿童进行普遍语言和言语迟缓筛查的有效性的建议和支持证据，以评估其短期和长期结果。我们使用关键词并在选定的来源中进行手动搜索，在 2019 年 11 月 20 日之前进行了文献检索。我们总结了建议和推荐强度，如其报告作者所述。我们总结了系统评价的主要结果，并根据筛查测试对语言和言语迟缓的准确性、对有语言和言语迟缓的儿童的现有干预措施的疗效以及与筛查和相关干预措施相关的潜在危害的准确性报告了证据的确定性。有几种筛查工具可用于评估语言和言语迟缓，其准确性差异很大。针对性干预措施可改善言语和语言迟缓及障碍的某些指标。但是，没有证据表明在没有特定关注儿童言语或语言的情况下，通过筛查发现儿童后进行此类干预措施对筛查出的儿童有效果。没有证据评估在初级保健环境中进行普遍语言和言语迟缓筛查是否能改善短期和长期结果（包括言语和语言结果和其他结果）。最后，没有证据表明在初级保健环境中筛查语言和言语迟缓存在危害，也没有评估干预措施潜在危害的有限证据。
