Understanding capacity for implementing new interventions: A qualitative study of speech and language therapy services for children with speech sound disorder.

What is already known on the subject Many SSD interventions have an evidence base but are not widely adopted into routine clinical practice. Addressing this is not just about individual therapists or education/training, as workplace pressures and service delivery models make it difficult to change practice. What this paper adds to the existing knowledge This paper applies innovations from implementation science to help explain how what is going on in services can support or constrain capacity for implementing evidence-based SSD interventions. What are the potential or actual clinical implications of this work? Service managers and therapists will have a clearer idea of the time and support they may realistically have to invest for new SSD interventions to be used routinely.
