- Among cochlear implant recipients, the youngest children (ages 1-2 years) have the highest rates of infectious complications.
Why this matters
- These authors say that the absolute risk is quite low and is outweighed by the benefits from implants for language development.
- Median age at implantation: 4 (interquartile range, 2-8) years.
- 3.2% had infectious complications.
- Rate was 8.2 (95% CI, 6.6-10.2) complications per 1000 person-years.
- Highest rates were among children ages 1 and 2 years:
- Age 1 year: 15.4 per 1000 person-years.
- Age 2 years: 14.8 per 1000 person-years.
- Adults in this study had similar rates, regardless of age, and an overall rate of 5.2 per 1000 person-years.
- The most common infectious complication was prosthetic infection/inflammation (40% of cases).
- Meningitis cases were rare (n
- Retrospective cohort study, US state databases, including all implant recipients age 1 year or more (1975 children, 5474 adults).
- Funding: National Institute on Deafness and Other Communication Disorders; others.
- Limited sensitivity for outpatient or nonsurgical complications.
- Diagnostic codes (ICD) for infectious complications not validated in other studies.
