Diagnostic Delays in Spasmodic Dysphonia: A Call for Clinician Education
Open accessAbstract
Purpose Spasmodic dysphonia (SD) is a rare but often debilitating disease. Due to lack of awareness among practitioners and lack of well-defined diagnostic criteria, it can be difficult for patients with SD to receive a diagnosis and subsequent treatment. There is currently no literature documenting the efficacy of the medical community in recognizing and diagnosing this disorder. We aimed to quantify the patients' experiences with obtaining a diagnosis of SD.Methods One hundred seven consecutive patients with SD completed questionnaires about their experiences with SD. Patients were recruited either during outpatient laryngology visits or during participation in a National Institutes of Health funded study investigating SD.Results It took patients an average of 4.43 years (53.21 months) to be diagnosed with SD after first going to a physician with vocal symptoms. Patients had to see an average of 3.95 physicians to receive a diagnosis of SD. Patients (31.4%) had been prescribed medications other than botulinum toxin to treat their symptoms. Patients (30%) attempted alternative therapies for treatment of SD, such as chiropractor or dietary modification.Conclusions Despite advances in diagnostic modalities in medicine, the diagnosis of SD still remains elusive. Objective criteria for the diagnosis of SD and increased clinician education are warranted to address this diagnostic delay.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“However, reliable diagnostic tools for SD remain absent, resulting in frequent misdiagnoses and an average 4.4-year delay before appropriate intervention (41).”

“In clinical practice, the diagnosis of Spasmodic Dysphonia (SD) primarily relies on clinical professionals' auditory perceptual assessment—an inherently subjective process prone to variability due to differences in expertise and experience (41).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
