Defining and predicting tracheoesophageal puncture success.

There is considerable variability in the reported success rates of tracheoesophageal puncture due, in part, to the lack of a clear definition of success and a paucity of knowledge about factors that determine success. In this article, we define success on a continuum with the use of a 15-point rating scale that incorporates aspects of use and quality of speech and ability to care for the fistula and prosthesis. We suggest a cutoff score for functional and nonfunctional speakers. We define immediate and short- and long-term success. Variables related to the patient, clinician, surgical procedure, and extent of disease were subjected to a multiple regression analysis to determine which predicted success. Overall success was predicted by greater clinician expertise, younger patient age, and better patient health. We discuss the use of the rating scale and an equation to predict success.
