To describe and communicate data collected in the CHEER Infrastructure proof of concept study to facilitate understanding of the potential capabilities of practice-based research networks, and to present pilot data for development of future research initiatives.
Prospective observational study of CHEER infrastructure operational capacity using a convenience sample of all patients presenting to the practices with tinnitus, dizziness, or a combination of these symptoms.
The CHEER Network of community and academic practice sites.
Subjects and Methods
The data collection exercise collected demographic, clinical, treatment, and health-related quality of life surveys on tinnitus, dizziness, and migraine disorders. Descriptive analysis of the data is presented.
Of the sites in the CHEER network, 73% (16/22) successfully enrolled subjects; a total of 1532 patients were enrolled in 8 months. Tinnitus alone, dizziness alone, and both occurred in 28%, 34%, and 29%, respectively. Patients complaining of tinnitus and dizziness had lower quality of life than those sufferers with one disorder. Migraine was associated with 27% of patients. The most frequent diagnoses for patients with tinnitus and dizziness were Ménière’s disease (34%), vertiginous migraine (18%), and benign paroxysmal positional vertigo (16%).
Descriptive data on patients with common disorders can be rapidly collected within the framework of a practice-based research network. Our data provide valuable pilot information on the targeted disorders, providing a baseline for development of future epidemiological data and clinical trials.
