Summary
Cochlear implantation rates show a bimodal distribution, peaking in young children (2-9 years) and older adults (60-69 years). Hospital charges for these procedures exceeded $12,000, varying by stay length and year.
Area of Science:
- Audiology
- Otolaryngology
- Health Services Research
Background:
- Limited data exists on cochlear implant (CI) utilization in large populations.
- Understanding CI epidemiology is crucial for resource allocation and patient care.
Purpose of the Study:
- To analyze correlates of cochlear implantation procedures in a large, diverse population.
- To identify demographic trends and cost factors associated with CI procedures.
Main Methods:
- Utilized a statewide hospital discharge database to identify CI procedures.
- Analyzed demographic data (age, sex) and procedure-related costs.
- Calculated age-specific incidence rates for CI.
Main Results:
- 146 CI procedures were identified; 55% involved female patients.
- Bimodal age distribution observed: highest rates in 2-9 years (5.4/million) and 60-69 years (3.7/million).
- Average hospital charges exceeded $12,000 per implant, varying by length of stay and year.
Conclusions:
- Cochlear implantation shows distinct utilization patterns across age groups.
- Significant cost variations exist, influenced by clinical and temporal factors.
- This study provides unique insights into CI epidemiology and utilization in a broad population.
