Questions Used to Obtain the National Baseline Data: 

    From the 2004 National Health Interview Survey:

    [DENOMINATOR:]

    Persons aged 18 years and over:

    2. A little trouble
    3. A lot of trouble
    4. Deaf
    5. Refused
    6. Don’t know
Data Collection Frequency: 
Periodic
Methodology Notes: 

    A cochlear implant is a medical device that bypasses damaged structures in the inner ear and directly stimulates the auditory nerve, allowing some deaf stimulates the auditory nerve, allowing some deaf individuals to hear and to maintain or develop speech and language.

    The numerator for this measure, number of cochlear implant (CI) surgeries, is derived from two databases in the HCUP system, because CI surgeries can be performed as inpatient surgeries or, increasingly, on an ambulatory basis in hospital-affiliated clinics. These databases are:

    1) The Nationwide Inpatient Sample: The largest all-payer inpatient care database in the United States, which contains data on more than seven million hospital stays from approximately 1,000 hospitals. and

    2) The State Ambulatory Surgery Databases (SASD): State databases that capture records from hospital-affiliated ambulatory surgery sites on surgeries performed on the same day in which patients are admitted and discharged.

    CIs are coded in HCUP by ICD-9-CM procedure codes 20.96-20.98, which are used by all the hospitals or hospital-affiliated outpatient clinics included in HCUP.
    Annual CI surgery data from Nationwide Inpatient Sample are available as nationally-weighted estimates from HCUP, and can be further classified by age categories, gender, and race.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2017, the original target was revised from 84.7 to 84.5 per 10,000 due to target recalculation based on 10% improvement target setting method.
