Objective
Systematically moving toward patient-centered care for unilateral vocal fold immobility (UVFI) requires comprehensive understanding of the variability of actual patient experiences. This rigorous qualitative study assesses UVFI-related disability and proposes a preliminary taxonomy of UVFI patient experience.
Study Design
1) Semi-structured interviews, 2) taxonomy development
Methods
Consecutive UVFI patients presenting July - September 2012 prospectively underwent open-ended interviews investigating how UVFI affected their quality of life (QOL) and had caused disability. Comments reported by >20% were synthesized into axes based on content similarity. Variables were arranged into a preliminary taxonomy of UVFI patient experience, which was evaluated for four attributes of face validity.
Results
The majority of 39 patients had “extensive” baseline voice use (56%) and an iatrogenic etiology (62%). Taxonomy of patient experience included 3 main axes of symptomatic classification: 1) voice, 2) swallowing, and 3) breathing - all with intrinsic (physical, emotional) and extrinsic (social) sub-axes that describe major impacts on QOL. Voice complaints were 100% penetrant, while breathing and swallowing symptoms afflicted 76% and 66% of interviewees. Of affected patients, solid and liquid dysphagia was experienced by 70% and 63%. Of dyspneic patients, shortness of breath existed with talking (97%) and exercise (72%). Persistent throat congestion (76%), weakened cough (62%), globus (62%), and dysfunctional valsalva (41%) were frequent.
Conclusion
Patient experience with UVFI has been incompletely characterized. This qualitative assessment and preliminary taxonomy highlight several related patient experiences not well documented in the literature or incorporated into currently available metrics.
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.
