Personalized, performance-specific speech intervention in children with a cleft palate: A systematic review protocol.

Background: The provision of speech intervention in children requires personalized, child-tailored approaches. Different speech-intervention approaches exist to eliminate cleft-related speech errors in children with a cleft palate. However, it is unclear what approach works best for the subtypes of cleft-related speech errors.

Aims: To describe a protocol for a systematic review that provides speech-language pathologists with the current literature concerning more individualized speech intervention in children with a cleft palate.

Methods & procedures: A systematic literature review was performed following the preferred reporting items for systematic reviews and meta-analyses. Two speech-language pathologists with clinical and scientific experience in cleft speech searched different electronic databases for relevant studies. No limit regarding publication date was set. Specific eligibility criteria were defined and used to include or exclude the studies. All included studies were evaluated with a risk-of-bias assessment tool and levels of evidence. Relevant data were extracted from the studies (study design, study population characteristics, intervention characteristics and outcome characteristics) and a narrative synthesis was performed.

Conclusions & implications: The findings of this systematic review will significantly contribute to the evidence on personalized speech intervention in children with a cleft palate. The study will inform speech-language pathologists on the possibilities to tailor treatment plans more to the specific subtype of cleft-related speech errors. The planned systematic review also makes recommendations for further cleft speech intervention research.

What this paper adds: What is already known on this subject At present, there is growing evidence for different speech therapy approaches in children with a cleft palate. Despite the recognized need for personalized, child-tailored therapy, there is no consensus on the best speech therapy approach per different subtype of compensatory cleft speech characteristic. What this study adds to the existing knowledge This paper provides a protocol for a systematic literature review of this topic. Specifically, it searches the literature for the use of personalized speech therapy approaches in children with different subtypes of compensatory cleft speech characteristics. What are the practical and clinical implications of this work? The systematic literature review provides speech-language pathologists with the current literature concerning personalized, performance-specific speech intervention in children with a cleft palate. Besides, the results will support therapy decision-making in children with a cleft palate in different speech-related clinical contexts.
