BACKGROUND: Ongoing contention surrounding typical demographic and clinical attributes of chronic cough (CC) and paradoxical vocal fold motion (PVFM) impedes timely diagnosis and optimum patient care. Designed to reduce preventable patient morbidity through improved recognition and differentiation, the current study aimed to determine representative clinical profiles for CC and PVFM, with identification of distinctive attributes from the general population and risk factors associated with each diagnosis.
METHODS: Self-reported medical questionnaires, demographic and lifestyle attributes of CC and PVFM cases from a disease-specific outcomes database were compared to US population data and published normative values. Univariate comparison and multivariate regression modelling of age, sex, alcohol intake, smoking, Reflux Symptom Index (RSI), Voice Handicap Index (VHI), and Generalized Anxiety Disorder 7-item Scale (GAD-7) determined distinguishing features between the clinical groups, including odds ratios for presenting with CC versus PVFM.
RESULTS: Clinical profiles developed from 283 (128 CC, 155 PVFM) adults (18-91 years) were significantly different from the general population across each demographic, lifestyle and clinical variable (all p < .01), with the exception of obesity. Age (55.39 ± 13.54 vs 45.07 ± 16.51 years, p < .01) and mean RSI score (21.5 ± 9.02 vs 18.1 ± 9.08, p < .01) most reliably distinguished CC from PVFM, with those aged 60-69 years (OR = 9.45) most likely to be diagnosed with CC.
CONCLUSIONS: Standard clinical profiles of CC and PVFM are distinct from the general population, aiding determination of relative probabilities and risk factors in the differential diagnostic process. Variations between CC and PVFM were subtle, reliably distinguished by age and relative severity of laryngopharyngeal reflux symptomatology.
