To monitor the reliability of our audio processors, we calculate the “Monthly Service Rate (MSR).”1 This number reflects the percentage of devices in the field which are returned for service. MED-EL has taken the industry lead in reporting reliability of external parts.
Average Monthly Service Rate
Our data is prepared in full accordance with ISO 5841-2:20002 and based on European and American consensus discussions between industry, medical professionals, and regulatory agencies.
We evaluate reliability using a special statistic called the Cumulative Survival Rate (CSR). The CSR statistic is the same one that is used to evaluate pacemaker reliability. MED-EL follows the reporting procedure in accordance with ISO 5841-2:20002. The CSR reporting method allows you to visualize how reliable our devices are over time.
