Hoarseness of unclear origin in adults

Time to Laryngoscopy for Hoarseness in Canada: Are the American Academy of Otolaryngology Guidelines Feasible?

Objectives

To determine if a Canadian voice center is meeting the recommended time to laryngoscopy for hoarseness per the clinical practice guideline of the American Academy of Otolaryngology–Head and Neck Surgery.

Study Design

Retrospective chart audit.

Setting

Tertiary referral Canadian voice center.

Participants and Methods

A total of 149 adult patients presenting with hoarseness over 6 months were included. Primary outcome measures were the time from onset of symptoms to laryngoscopy and the time from referral to laryngoscopy. Secondary outcome measures included patient- and disease-modifying factors, diagnosis, and clinical management. Analysis was performed to determine what factors were associated with meeting the guideline.

Results

Patients were evaluated by the laryngologist after 21.9 ± 37.6 months (mean ± SD) of symptoms. One-third (34.2%) of patients were seen within 3 months; 10.7% were seen within 4 weeks. Logistic regression showed that patients with neurologic symptoms (odds ratio, 4.04; 95% CI, 1.31-12.43; P = .015) and endotracheal intubation (odds ratio, 5.94; 95% CI, 2.21-15.95; P < .001) were associated with being seen within 3 months. Patients who had recent intubation (odds ratio, 6.04; 95% CI, 1.99-18.34; P = .002) were associated with being seen within 4 weeks.

Conclusion

It is an ongoing challenge for our Canadian voice center to meet the American Academy of Otolaryngology–Head and Neck Surgery’s clinical practice guideline for recommended time to laryngoscopy. Patients with more severe pathologies were consistently triaged more urgently. It is debatable whether this 4-week time recommendation is generalizable to a socialized health care system.
