Evaluating the use of oral trials for inpatient dysphagia management: a
cross-sectional database study
Abstract
Rationale, aims and objectives: Oral trials, otherwise known as swallow
trials or tasters, are widely used in dysphagia management. However, to
date, no studies have investigated the effectiveness of oral trials or
outlined how the approach is utilised in everyday practice. This paper
aims to (1) Identify the patient demographics and environments in which
oral trials are used in hospital. (2) Explore clinical decision-making
around the approach. Method: A cross-sectional examination of 118
patients on the dysphagia caseload of a UK-based inpatient Speech and
Language Therapy team was conducted. Statistical analysis explored
demographic differences between oral trials groups and the rest of the
dysphagia caseload. Results: 19.5% (23/118) of individuals on the
caseload were or had been on oral trials during admission. Individuals
in the oral trials group were significantly more likely to have a
neurological diagnosis than the full oral intake group (78.3% vs
30.5%, p<0.001). There was a lack of uniformity in oral
trials recommendations and the rationale behind quantity and types of
diet or fluids offered was unclear. Conclusions: This study begins to
evidence the use of a dysphagia therapy not previously explored within
existing literature. It highlights the wide use of oral trials within
the hospital observed. Neurological diagnosis was a key predictor of
belonging to the oral trials group. Further research into the
effectiveness and implementation of oral trials is warranted. Keywords:
