Objective:
To determine the cost-effectiveness of middle-ear implantations in hearing-impaired patients with severe external otitis in the Netherlands.
Design:
Cost-effectiveness analysis, using single-subject repeated measures of quality of life and total cost determinations.
Setting:
Hospital based. Patients Moderately to severely sensorineurally hearing-impaired patients (n = 21) with severe chronic external otitis, eligible to receive a middle-ear implant. Main Outcome Measure Cost per quality-adjusted life-year (QALY), based on scores of the Medical Outcomes Study Short-Form Health()Survey (SF-36) generic quality of life questionnaire. Only direct costs were included in cost calculation of middle-ear implantation.
Results:
Mean health utility gain was 0.046 (0.012-0.079) (P = .01) measured at the mental component of the SF-36. With a mean profitable time of 19.4 years and an overall cost of euro 14,354, minimal cost-effectiveness of middle-ear implantation was euro 16,085/QALY.
Conclusion:
Based on the cost per QALY, middle-ear implantation proved to be a cost-effective and justified health care intervention in the Netherlands.
