To develop and examine user acceptance and content validity of a structured program to facilitate safe but challenging oral intake during radiotherapy (RT) delivered by a speech language pathologist (SLP)-the Eat-All Through Radiation Therapy (EAT-RT) program. EAT-RT was developed through expert consensus of SLPs at the Princess Margaret Cancer Centre (Canada) and M D Anderson Cancer Center using a conceptual framework of a diet hierarchy and a mealtime routine. EAT-RT was refined by practicing SLPs, and then disseminated for a 4-week clinical pilot at seven sites who were subsequently invited to participate in an online survey. Twelve SLPs from six sites piloted EAT-RT therapy with a median of eight patients (IQR: 2-15) before and/or during RT. All SLPs reported EAT-RT added value to their practice, harmonized well with exercises, and its content was helpful; 11 (92%) reported EAT-RT facilitated patient understanding and indicated the desire to continue using EAT-RT. The EAT-RT program was accepted by North American SLPs. The findings support the content and value of EAT-RT to facilitate oral intake in patients with head and neck cancer throughout RT.
