Results indicate the need to increase SLP familiarity with, and access to, currently available standardized assessments, as well as to improve education regarding the fundamental need to rate speech to assess intelligibility. Clinicians may also benefit from new standardized methods to objectively assess intelligibility that are accessible, practical, and efficient.
Lenition (German
Lenierung
, from Latin
lenire
‘weaken’) is most commonly defined as “a ‘relaxation’ or ‘weakening’ of articulatory effort” (Hock 1991: 80). The term was coined by Thurneysen as one “used to describe a mutation of consonants which normally originated in a reduction of the energy employed in their articulation,” and affects mostly consonants in intervocalic position (Thurneysen 1946: 74).
Purpose
Speech-language pathologists (SLPs) are trained to evaluate and treat dysphagia. One treatment method is to modify diet consistency or viscosity to compensate for swallowing dysfunction and promote a safer intake; this typically involves softening solids and thickening liquids. Thickening liquids is not safer for all patients, and modification of dysphagia diets without adequate training may reduce the quality of dysphagia patient care. Over 90% of SLPs working in health care report exposure to nurses who regularly downgrade dysphagia diets without an SLP consult. This study explores dysphagia diet modification practices of nursing staff with and without dysphagia training.
Method
Practicing nurses and student nurses (
N
= 298) in the United States were surveyed regarding their dysphagia diet modification training and practice patterns. Additionally, a pre-/posttest design was used to determine the efficacy of a short general tutorial on willingness to modify diets without an SLP consult.
Results
Downgrading diets without an SLP consult is a common practice. Fewer than one third of nurses (31.41%) would avoid it, whereas 73.65% would avoid upgrading without SLP consult. Formal dysphagia training made little difference to this practice. The short general tutorial also had no beneficial effect, in fact slightly reducing the willingness to consult SLPs.
Conclusions
Dysphagia diet modification practice by nurses is pervasive in U.S. health care. This is a previously unexplored but common issue SLPs face in work settings. This study identifies a need to clarify guidelines and increase interprofessional education between both professions to improve patient care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
