ObjectiveTreatment options for adults with chronic cough (CC) are limited. This study reports on the health status and experiences of patients with recent healthcare evaluation for CC.MethodsThis prospective, UK, cross-sectional study surveyed adults with a CC evaluation within the previous 12 months. All were never smokers (or ex-smokers for ≥12 months). Subjects completed five validated patient-reported outcome measures: cough visual analogue scale (VAS), EuroQoL 5 dimension, 5 level (EQ-5D-5L), EQ-5D VAS, Leicester Cough Questionnaire (LCQ), and Work Productivity and Activity Impairment (WPAI) questionnaire.ResultsA total of 101 participants were recruited: 71% were female, mean age was 54.9 ± 15.2 years. Median (IQR) CC duration was 36 (11, 120) months. Mean self-reported CC severity (Cough-VAS) was 51.3 ± 22.9 over the previous 2 weeks and 62.9 ± 23.7 on the worst day of coughing. EQ-5D values were lower for CC patients than population norms. Subanalyses revealed that EQ-5D and LCQ scores were significantly impacted by CC duration and the number of healthcare providers (HCPs) visited. WPAI analysis showed a 27.6% work time impairment because of participants' CC. The number of HCP attendances ranged from 1 to 10 (3.3 ± 2.8) before diagnosis was confirmed. Treatment was being prescribed to 87% of participants and comprised mainly steroids (nasal [19%] and inhaled [25%]), beta agonists (24%), and proton pump inhibitors (21%); 44% of patients were dissatisfied with treatment efficacy.ConclusionReal-world data from a nationally representative UK population show significant unmet needs associated with CC, including multiple healthcare visits and limited treatment effectiveness, resulting in inadequate cough control and impaired health status.
