Evaluation of the Implementation of a Speech and Language Therapist-Led Referring Model for VFSS Using the Consolidated Framework for Implementation Research (CFIR)

Background: Speech and language therapists (SLTs) use videofluoroscopic swallow study (VFSS) results to manage dysphagia. Yet, in some services only doctors can directly request a VFSS, potentially creating workflow inefficiencies and delaying patient access to VFSS. An alternative model, where SLTs directly refer patients for VFSS, is used in many services in the UK and Australia. However, processes for implementing and sustaining this model have not been reported. Aims: To evaluate the implementation of an SLT-led inpatient VFSS referring model using the Consolidated Framework for Implementation Research (CFIR) to ascertain implementation barriers, facilitators and critical sustainability factors. Methods & Procedures: This implementation evaluation examined stakeholder perceptions of implementing the SLT-led VFSS referring model via interviews of (1) SLTs who treat and refer inpatients for VFSS; (2) doctors who manage and refer inpatients for VFSS; (3) radiologists; and (4) trained VFSS referring SLTs. The CFIR was used to prospectively guide implementation planning, evaluation and outcome reporting, regarding barriers, facilitators and sustainability factors. Outcomes & Results: Implementation facilitators were (1) the advantage of SLT-led VFSS referring over the standard model (doctors referring), in promoting high-quality VFSS referrals; (2) compatibility of the model with the SLT skill set; (3) supportive communication networks between staff groups; and (4) engaging stakeholders throughout implementation. Adequate availability of trained VFSS referring SLTs was both a barrier and a facilitator of implementation. It was also a critical sustainability factor, along with ongoing staff education and outcome monitoring. Conclusions & Implications: The CFIR supported systematic evaluation of implementation facilitators and barriers, and adjustment of factors critical for implementing and sustaining the new model. Findings may assist other organizations to establish the SLT-led VFSS referring model.
