Background and Objective: Patients who receive cochlear implants (CIs) constitutes a significant population in Iran. This population needs regular monitor on long-term outcomes, educational placement and quality of life. Currently, there is no national or regional registry on the long term outcomes of CI users in Iran. The present study aims to introduce the design and implementation of a national patient-outcomes registry on CI recipients for Iran. This Iranian CI registry (ICIR) provides an integrated framework for data collection and sharing, scientific communication and collaboration in CI research.

Methods: The national ICIR is a prospective patient-outcomes registry for patients who are implanted in one of Iranian centers. The registry is based on an integrated database that utilizes a secure web-based platform to collect response data from clinicians and patient’s proxy via electronic case report forms (e-CRFs) at predefined intervals. The CI candidates are evaluated with a set of standardized and non-standardized questionnaires prior to initial device activation (as baseline variables) and at three-monthly interval follow-up intervals up to 24 months and annually thereafter.

Results: The software application of the ICIR registry is designed in a user-friendly graphical interface with different entry fields. The collected data are categorized into four subsets including personal information, clinical data, surgery data and commission results. The main parameters include audiometric performance of patient, device use, patient comorbidities, device use, quality of life and health-related utilities, across different types of CI devices from different manufacturers.

Conclusion: The ICIR database could be used by the increasingly growing network of CI centers in Iran. Clinicians, academic and industrial researchers as well as healthcare policy makers could use this database to develop more effective CI devices and better management of the recipients as well as to develop national guidelines
