Clinical Trial Summary

Achieving speech that is understandable and acceptable to others is the key outcome in cleft treatment. Therefore, speech therapy provided by a speech-language pathologist is necessary. This intervention is traditionally provided twice per week for 30 minutes for months or even years by first-line speech-language pathologists. Unfortunately, this low intensity intervention is based on a historical context rather than scientific evidence. This means that current speech therapy knows several shortcomings including poor outcomes, treatment fatigue and high costs related to year-long therapy. Because of these issues, the use of high intensity speech intervention is proposed. Even though solid proof-of-concepts exist for this model, it has not yet found its way into clinical practice. Before this intensity can be implemented and utilized in clinical practice, the effect of this novel program on a larger societal scale must be determined. This project will compare the effect of high intensity and low intensity speech intervention in children with a cleft palate in terms of speech, quality of life, and cost-utility as provided by first-line speech-language pathologists by conducting a large-scale randomized controlled trial. The final goal is to utilize this program in clinical practice and to create awareness of the benefits for children with a cleft palate among stakeholders.

Clinical Trial Description

Objective 1: Conduct a large-scale randomized controlled trial to compare the short- and long-term sustainable effects of two different speech intervention intensities (i.e. high intensity speech intervention: 5x30 min/week during 2x4 weeks (2x10 hours) and low intensity speech intervention: 2x30 min/week during 20 weeks (20 hours)) on the speech and quality of life in Belgian Dutch-speaking children with a cleft palate with or without a cleft lip. Speech intervention will be provided by first-line speech language pathologists in private practices who will receive thorough training before the onset of the trial. Hypothesis 1: Based on the state-of-the-art and our proof-of-concept, it is assumed that 20 hours of high intensity speech intervention will lead to superior speech outcomes and health-related quality of life compared to 20 hours of low intensity speech intervention. Objective 2: To compare the cost-utility in quality-adjusted life years of two different speech intervention intensities (i.e. high intensity speech intervention: 5x30 min/week during 2x4 weeks (2x10 hours) and low intensity speech intervention: 2x30 min/week during 20 weeks (20 hours)) in Belgian Dutch-speaking children with a cleft palate with or without a cleft lip. Demonstrating the cost-effectiveness of high intensity speech intervention will facilitate implementation and utilization of this protocol in clinical practice as less money has to be spent in order to gain one life year in full health (QALY) when providing high intensity speech intervention compared to low intensity speech intervention. Hypothesis 2: Besides the superior speech outcomes and health related quality of life in a shorter intervention time (cfr. hypothesis 1), it is hypothesized that less money has to be spent in order to gain one life year in full health (QALY) in the high intensity intervention group. In other words, it is hypothesized that high intensity intervention will be more cost-effective compared to low intensity speech intervention. ;
