Diagnosis and Treatment of Refractory Chronic Cough: An American Broncho‐Esophagological Association Expert Consensus Statement

OBJECTIVE: To develop an expert consensus statement (ECS) on the diagnosis and treatment of refractory chronic cough (RCC) in adults. RCC was defined as cough lasting longer than 8 weeks and refractory to standard management of pulmonary, gastrointestinal, sinonasal, and medication-induced etiologies. METHODS: An expert panel of otolaryngologists used published consensus statement methodology to develop statements guiding the diagnosis and management of RCC from an otolaryngologic perspective. A modified Delphi method was used to iteratively select, eliminate, and refine statements based upon accepted methodology until consensus was achieved. RESULTS: Three iterative Delphi surveys were performed with discussion rounds between each of the voting sessions. Twenty-seven statements met consensus while six statements did not. The clinical statements were grouped into 9 categories: operational definition, pathophysiology, assessment of prior work-up, phenomenology and symptomatology, four treatment categories (neuromodulators, superior laryngeal nerve blocks, behavioral cough suppression, and emerging treatments), and overall treatment approaches. CONCLUSION: The panel reached consensus for 27 statements related to the diagnosis and treatment of adults with RCC from an otolaryngologic perspective. These statements may be used to standardize evaluation and improve quality of care, while also identifying areas for future investigation in the management of RCC.
