 Abstract

Approximately 700 children are born each year in the UK with a cleft palate. 20% of these children are either barely intelligible or entirely unintelligible at age 5 and are described as having persistent speech disorder. Persistent speech disorder is associated with poor outcomes in education, employment and mental health. A review of studies of speech and language therapy interventions for children born with cleft palate found that there was not enough evidence to say which type or pattern of delivery of intervention is most effective for these children in reducing the number who have persistent speech disorder at age 5. A national study, the Cleft Collective Speech and Language Study, has been set up to investigate speech development from birth to age 5 in children born with cleft palate and to provide a comprehensive dataset which can be used by future researchers. With additional funding, it would also be possible to collect data on the types of speech and language therapy intervention children receive within the national cohort study. This would enable us to determine which types of speech and language therapy intervention are associated with good speech outcomes in these children, leading to fewer children who are barely intelligible or entirely unintelligible at age 5. A series of focus groups with speech and language therapists (SLTs) have been undertaken to determine the content for a survey of speech and language therapy (SLT) intervention for children who are participating in the cohort study. The aims of this project were: - To identify which interventions are being delivered for children born with cleft palate across the UK and discover how they are being delivered. - To develop an electronic survey for data collection in the CC-SL Study, to obtain information on the types of speech and language therapy interventions and patterns of service delivery received by participants. Focus groups with Cleft Specialist SLT teams, with participation from community SLTs, were completed. During the focus groups, a number of domains of SLT intervention and patterns of service delivery were explored including: age of child at intervention; frequency of sessions; duration of individual sessions/episode of care; content of intervention; location and agent of delivery. During these focus groups, definitions and terminology were clarified. When saturation occurred, the researchers conducted knowledge elicitation activities during the focus groups to build on outputs from earlier focus groups. Nvivo 10 software was used for data organisation and analysis. Iterative content analysis identified codes and resultant questions for use in the survey. A pilot survey was drafted using REDCap software. SLTs working with children born with cleft palate piloted the survey and provided feedback related to the layout, clarity and time taken to complete the survey. Survey questions and response options were amended based on the pilot findings and a final version was agreed. A protocol for use of the survey within the CC-SL Study has been written and an amendment to the study's ethics has been accepted. Once the survey is live across the CC-SL Study, data on SLT interventions for children within the cohort will be collected. A subsequent funding application will be made to analyse the data collected for the purpose of identifying the impact of SLT interventions on speech outcomes in children born with cleft palate. This study will involve an epidemiological analysis of the speech outcome data collected within the cohort study to identify associations between outcomes for speech and interventions received. Analyses will include adjustment for severity of speech disorder (using baseline measures of speech at age 13 months) and for known confounders such as socio-economic status, type and timing of surgery and developmental level of the child and parental engagement with speech and language therapy intervention.

Main findings

  • The project has identified a wide number of speech and language therapy interventions which are being delivered to children born with cleft palate across the UK.
  • Similarities and differences were reported nationally with regards to how services deliver intervention and what influences the Speech and Language Therapist's decision making when planning this intervention. 
  • Many intervention approaches that are used frequently were found to have weak evidence for how well they work. This is an issue to be addressed in future research.

Impact

Findings have provided information about what interventions are being delivered to children born with cleft palate across the UK and how this is provided. This information has been used to develop a survey for the Cleft Collective Speech and Language Study. This survey will be completed by Speech and Language Therapists to provide intervention data, which will be used to answer research questions in the future. Research questions will aim to discover the most effective interventions for children born with a cleft palate. If these are used by Speech and Language Therapists we would hope to see improved outcomes for this group of children.

Other project outcomes

The key outcome from this work is the development of a survey which will collect data on SLT interventions received by children in the Cleft Collective Speech and Language Cohort Study. This information will expand the dataset, which is available for any research to apply to access. It will also be used by the applicant team from this award to determine the impact of existing interventions and patterns of service delivery on outcomes for children in the cohort study. Findings from this work will provide information on the specification of an intervention to be used in a future trial. Plans for a funding application to use the data are on hold while we establish the process for collecting the data and until we have sufficient data to make analysis worthwhile. To date, over 350 children have been recruited to the study but they are recruited at birth and the survey of SLT intervention takes place when they are five years old. A handful of children in the study have reached five years, but we need to wait for more before we will have sufficient data to use. Alongside succeeding in the core deliverable of developing and implementing a survey of SLT intervention, we have achieved the following outcomes:

  • Development of clinical researcher - Caroline Williams, SLT with the Newcastle upon Tyne Cleft team, was employed to work on this study. With support from the team at BSLTRU, she has successfully carried out the bulk of the work outlined in the proposal and has developed research skills along the way. She is currently preparing a bid to the NIHR ICA PCAF scheme. 
  • Maintenance of strong collaborations with regional cleft lip and palate services across the UK 
  • The Cleft Collective is a longitudinal cohort study which collects data from regional specialist clinical services across the UK. The focus group work has been essential to ensuring that the voice of SLTs has been considered in the development of the survey and refinements have been made in response to their feedback. The funding from this award has been pivotal in enabling this and has enabled us to provide what the clinical teams requested in terms of their involvement in the research process.
