Applying evidence to practice by increasing intensity of intervention for children with severe speech sound disorder: a quality improvement project

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

BACKGROUND

Many speech sound disorder (SSD) interventions with a long-term evidence base are 'new' to clinical practice, and the role of services in supporting or constraining capacity for practice change is underexplored. Innovations from implementation science may offer solutions to this research-practice gap but have not previously been applied to SSD.

AIM

To explain variation in speech and language therapy service capacity to implement new SSD interventions.

METHODS & PROCEDURES

We conducted an intensive, case-based qualitative study with 42 speech and language therapists (SLTs) in three NHS services (n = 39) and private practice (n = 3) in Scotland. We explored therapists' diverse experiences of SSD practice change through individual interviews (n = 28) or self-generated paired (n = 2) or focus groups (n = 3). A theoretical framework (Normalization Process Theory) helped us understand how the service context contributed to the way therapists engaged with different practice changes.

OUTCOMES & RESULTS

We identified six types ('cases') of practice change, two of which involved the new SSD interventions. We focus on these two cases ('Transforming' and 'Venturing') and use Normalization Process Theory's Cognitive participation construct to explain implementation (or not) of new SSD interventions in routine practice. Therapists were becoming aware of the new interventions through knowledge brokers, professional networks and an intervention database. In the Transforming case, new SSD interventions for selected children were becoming part of local routine practice. Transforming was the result of a favourable service structure, a sustained and supported 'push' that made implementation of the new interventions a service priority, and considerable collective time to think about doing it. 'Venturing' happened where the new SSD interventions were not a service priority. It involved individual or informal groups of therapists trying out or using one or more of the new interventions with selected children within the constraints of their service context.

CONCLUSIONS & IMPLICATIONS

New, evidence-based SSD interventions may be challenging to implement in routine practice because they have in common a need for therapists who understand applied linguistics and can be flexible with service delivery. Appreciating what it really takes to do routine intervention differently is vital for managers and services who have to make decisions about priorities for implementation, along with realistic plans for resourcing and supporting it.

WHAT THIS PAPER ADDS

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.

Outcome measures for children with speech sound disorder: an umbrella review

OBJECTIVE

Speech sound disorder (SSD) describes a 'persistent difficulty with speech sound production that interferes with speech intelligibility or prevents verbal communication'. There is a need to establish which care pathways are most effective and efficient for children with SSD. Comparison of care pathways requires clearly defined, evidence-based, interventions and agreement on how to measure the outcomes. At present, no definitive list of assessments, interventions or outcomes exists. The objective of this umbrella review paper is to provide a rigorous and detailed list of assessments, interventions and outcomes which target SSD in children.

DESIGN

In December 2022, a systematic search of Ovid Medline, OVID Embase, CINAHL, PsycInfo and Cochrane and a number of grey literature platforms were undertaken. 18 reviews were included, and subsequently 415 primary research articles were assessed for data related to assessments, interventions or outcomes. The AMSTAR (Assessing the Methodological Quality of Systematic Reviews) framework was used to assess the quality of the retained reviews.

SETTING

Reviews were retained which took place in any setting.

PARTICIPANTS

The population is children of any age with a diagnosis of SSD of unknown origin.

PRIMARY AND SECONDARY OUTCOME MEASURES

Reviews reporting outcomes, assessment and interventions for children with SSD.

RESULTS

Extraction and analysis identified 37 assessments, 46 interventions and 30 outcome measures used in research reporting of SSD. Not all of the listed outcomes were linked to specific outcome measurement tools, but these were measurable through the use of one or more of the assessments extracted from the retained reviews.

CONCLUSIONS

The findings of this review will be used to develop a Core Outcome Set for children with SSD. The findings are part of a rigorous process essential for advancing healthcare research and practice in the specific area of speech and language therapy for children with SSD.

What works, how and in which contexts when supporting parents to implement intensive speech and language therapy at home for children with speech sound disorder? A protocol for a realist review

INTRODUCTION

Speech and language therapists (SLTs) worldwide report challenges with providing recommended, evidence-based intervention intensity for children with speech sound disorder (SSD). Challenges such as service constraints and/or family contexts impact on access to optimal therapy intensity. Existing research indicates that empowering and training parents to deliver intervention at home, alongside SLT support, offers one possible solution to increasing the intensity of intervention children with SSD receive. Digital health could increase accessibility to intensive home practice and help sustain engagement with therapy activities. Further exploration is needed around what makes parent-implemented interventions for children with SSD effective, for who and in which situations. This paper outlines the protocol for a realist review which aims to explore the active ingredients and contextual factors of effective digital parent-led interventions.

METHODS AND ANALYSIS

A realist review will explore the research question, following six stages. The scope of the review will be determined, and initial programme theories will be developed about what works in digital parent-implemented interventions for SSD, for whom, how, why and in what circumstances. Relevant secondary data, identified through a formal search strategy, will be selected, appraised, analysed and synthesised using realist principles to test and further refine the initial programme theories. This process will develop refined underpinning explanatory theories which capture the interaction between contexts, mechanisms and outcomes of the intervention. An expert steering group will provide insight to inform explanatory theories, searches, and dissemination.

ETHICS AND DISSEMINATION

Ethical approval is not required for this review. The refined programme theories from the review will inform the next stages of a wider study. A subsequent realist evaluation will test and further refine theories with key stakeholders. Following this, the underpinning programme theory will be used to coproduce a digital tool, to support parents to deliver home intervention alongside SLT support.

Speech assessment tool methods for speech impaired children: a systematic literature review on the state-of-the-art in Speech impairment analysis

Speech is a powerful, natural mode of communication that facilitates effective interactions in human societies. However, when fluency or flow of speech is affected or interrupted, it leads to speech impairment. There are several types of speech impairment depending on the speech pattern and range from mild to severe. Childhood apraxia of speech (CAS) is the most common speech disorder in children, with 1 out of 12 children diagnosed globally. Significant advancements in speech assessment tools have been reported to assist speech-language pathologists diagnosis speech impairment. In recent years, speech assessment tools have also gained popularity among pediatricians and teachers who work with preschoolers. Automatic speech tools can be more accurate for detecting speech sound disorders (SSD) than human-based speech assessment methods. This systematic literature review covers 88 studies, including more than 500 children, infants, toddlers, and a few adolescents, (both male and female) (age = 0-17) representing speech impairment from more than 10 countries. It discusses the state-of-the-art speech assessment methods, including tools, techniques, and protocols for speech-impaired children. Additionally, this review summarizes notable outcomes in detecting speech impairments using said assessment methods and discusses various limitations such as universality, reliability, and validity. Finally, we consider the challenges and future directions for speech impairment assessment tool research.

Outcome measures for children with speech sound disorder: an umbrella review protocol

INTRODUCTION

Speech sound disorder (SSD) describes a 'persistent difficulty with speech sound production that interferes with speech intelligibility or prevents verbal communication'. There is a need to establish which care pathways are most effective and efficient for children with SSD. Comparison of care pathways requires clearly defined, evidence-based interventions and agreement on how to measure the outcomes. At present, no list of assessments, interventions or outcomes exists.The objective of this paper is to provide a rigorous and detailed protocol for an umbrella review of assessments, interventions and outcomes that target SSD in children. The protocol details the development of a search strategy and trial of an extraction tool.

METHODS AND ANALYSES

The umbrella review has been registered with PROSPERO (CRD42022316284). Papers included can use a review methodology of any sort but must include children of any age, with an SSD of unknown origin. In accordance with the Joanna Briggs Institute scoping review methods guidelines, an initial search of the Ovid Emcare and Ovid Medline databases was conducted. Following this, a final search strategy for these databases were produced. A draft extraction form was developed.

ETHICS AND DISSEMINATION

Ethical approval is not needed for an umbrella review protocol. Following the systematic development of an initial search strategy and extraction form, an umbrella review of this topic can take place. Dissemination of findings will be through peer-reviewed publications, social media, and patient and public engagement.
