[Concept analysis of dysphagia].

Swallowing is a complex process. Dysphasia may interrupt normal life activities such as having meals with family and friends and enjoying food. Consequently, patients with dysphasia are less likely to attend social activities, which may lead to social isolation and frustration. A review of the literature in Taiwan revealed a lack of recent systematic analysis on dysphasia. The purpose of this article was to discuss dysphasia within the concept analysis framework provided by Walker and Avant (2004). This article verified and confirmed the conceptual characteristics of dysphasia; identified antecedents and consequences; and elaborated on previous cases (including model, borderline, contradictory, and related cases). Empirical referents of dysphasia were also explored. It is hoped that this paper may provide a better understanding of the concept of dysphasia, which nurses may apply to clinical practice.
