OBJECTIVE: To evaluate for equivalence in postoperative changes of speech recognition scores in a veteran patient population undergoing cochlear implantation (CI) compared to matched nonveteran patients.
STUDY DESIGN: Retrospective chart review.
SETTING: Tertiary referral center.
PATIENTS: A total of 83 veteran patients who underwent CI at a single Veterans Affairs Medical Center (VA cohort) were matched to 83 nonveteran patients from the Health Insurance Portability and Accountability Act-secure, Encrypted, Research, Management and Evaluation Solution database (HERMES cohort) based on age, sex, and baseline Consonant-Nucleus-Consonant (CNC) scores.
INTERVENTION: Patients underwent CI.
MAIN OUTCOME MEASURES: Comparison of postoperative CNC and Arizona Biomedical Institute recognition scores.
RESULTS: The mean difference and lower confidence interval of CNC scores between matched Veterans Affairs and HERMES cohorts were within a -ΔNI boundary of -15% at the 3-month (mean = 6.15, lower confidence interval = -2.38), 6-month (mean = 7.36, lower confidence interval = -2.21), and 12-month (mean = 4.03, lower confidence interval = -4.88) postoperative time points. The mean difference and lower confidence interval of Arizona Biomedical Institute scores between cohorts were within the -ΔNI boundary of -30% at 3 months (mean = 1, lower confidence interval = -8.71), 6 months (mean = 0.31, lower confidence interval = -12.30), and 12 months (mean = 0.72, lower confidence interval = -10.48).
CONCLUSION: Our veteran population demonstrated improvements in speech recognition scores after CI comparable to a matched nonveteran population. Although veterans face unique factors that affect their hearing, access to medical care, and baseline general health, these findings affirm appropriate veteran candidates should be offered CI.
