Page Background

Development of a Statistical Model for the Prediction

of Common Vestibular Diagnoses

IMPORTANCE

Treatment of patients with vestibular disorders can be complex, requires

lengthy clinic visit time, and uses greater clinical resources for diagnosis. A pre-encounter

intake questionnaire may predict the most common disorders, allowing for more efficient

allocation of resources and use of clinicians.

OBJECTIVE

To develop a statistical model for predicting vestibular diagnoses, prior to clinical

evaluation, from an intake questionnaire.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective review of 414 consecutive new vestibular

patient intake questionnaires (September 2012 through January 2014) and associated

medical records with performance of logistic regression analyses and development of

predictive models (July 2013 through May 2015).

INTERVENTIONS

Use of a vestibular intake questionnaire for triaging of new patients with

complaints of dizziness.

MAIN OUTCOMES AND MEASURES

Predictors for the diagnosis of benign paroxysmal

positional vertigo (BPPV), Ménière’s disease, and vestibular migraine.

RESULTS

Of the 414 questionnaires analyzed, 381 (92%) had clinician information necessary

to define a final diagnosis. Patients were 34%male and had a mean (range) age of 57 (19-91)

years. Of the diagnoses, 183 (48%) were ear related (including 103 BPPV and 49 Meniere's

disease), 141 (37%) neurological (including 109 vestibular migraine), 36 (9%) medical, 8 (2%)

of psychological origin, 46 (12%) of unknown etiology, and 33 (9%) other causes. The

diagnosis of BPPV could be predicted from 4 variables with a sensitivity of 79% and

specificity of 65%. The diagnosis of Ménière’s disease could be predicted from 5 variables

with a sensitivity of 81% and specificity of 85%. The diagnosis of vestibular migraine could be

predicted from 4 variables with a sensitivity of 76% and specificity of 59%.

CONCLUSIONS AND RELEVANCE

A pre-encounter history questionnaire can provide useful

diagnostic information for common vestibular disorders. This can help direct appointment

scheduling to improve clinical efficiency, time to intervention, and use of resources. Further

refinement may enable the use of shorter questionnaires or screening algorithms.
