Purpose:
Esophageal screening is a valuable inclusion in videofluoroscopic swallowing studies (VFSSs). However, routine standardized esophageal screening does not always occur in clinical practice. This study introduced and evaluated an esophageal screening protocol at one Australian hospital.
Method:
Radiology, gastroenterology, and speech-language pathology endorsed an esophageal screening protocol, which followed a timed 20-ml International Dysphagia Diet Standardisation Initiative Level 0 bolus from mouth to stomach in an upright anterior–posterior position. Measures exploring clinical impacts and barriers were recorded. Participants were compared with 100 consecutive VFSS patients prior to the introduction of the esophageal screening protocol.
Results:
During the esophageal screening protocol trial, 163 VFSSs were conducted with recruited patients. Aspiration risk (29%,
n
= 47/163) and positioning limitation (3%,
n
= 5/163) were barriers to esophageal screening. Rates of esophageal screening significantly increased with the esophageal screening protocol (χ
2
= 63.462,
p
< .001). There was no difference in radiation dose for patients who had esophageal screening and those who did not in the esophageal screening protocol group (
U
= 1689.000,
p
= .237). The VFSS team breached the esophageal screening protocol for some patients, when evaluating esophageal transit time (
n
= 28) and recommending gastroenterology referral (
n
= 6). There was no difference between groups for rates of gastroenterology consults (χ
2
= 1.805,
p
= .188) or dysphagia procedures (χ
2
= 1.951,
p
= .209).
Conclusions:
This study confirms that routine esophageal screening provides additional clinical information to assist holistic dysphagia management without adverse operational impacts. Further research with the multidisciplinary dysphagia team has commenced to continue to optimize and refine esophageal screening practice.
