biostudies-literatureUnknown17(12)Leong P<h4>Introduction</h4>Currently there is no consistent and widely accepted approach to the diagnosis of vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO). Harmonised diagnostic methods are vital to enable optimal diagnosis, advance management and enable research. We aim to obtain consensus on how expert clinicians recognise and diagnose VCD/ILO.<h4>Methods and analysis</h4>Two-round modified Delphi, with workshop validation.<h4>Ethics and dissemination</h4>Institutional Board Review was obtained from the Monash Health Human Research Ethics Committee. The dissemination plan is for presentation and publication.<h4>Registration details</h4>Registered at Australia and New Zealand Clinical Trials Registry ACTRN12621001520820p.PloS onee0279338https://www.ebi.ac.uk/biostudies/studies/S-EPMC9799289biostudies-literatureDiagnosis of vocal cord dysfunction / inducible laryngeal obstruction-A Delphi study protocol.PMC9799289Hew MGibson PGVertigan AEBaxter MPhyland DCarroll TLMcDonald VMHull JHBardin PGLeong PfalseDiagnosis of vocal cord dysfunction / inducible laryngeal obstruction-A Delphi study protocol.<h4>Introduction</h4>Currently there is no consistent and widely accepted approach to the diagnosis of vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO).
