Abstract

This paper prospectively documents the health-related quality of life (HRQoL) and social participation benefits of adult patients receiving cochlear implants in Australia and New Zealand. Thirty-four consecutively implanted patients completed the Assessment of Quality of Life (AQoL) and Hearing Participation Scale (HPS) instruments before implantation, and at 3– and 6–month follow-ups. Implantation resulted in significant improvements in AQoL and HPS scores. The effect size was 1.09 for both measures. Those in the top socio-economic tertile obtained the greatest gains. The HRQoL and social participation benefits were slightly larger than those reported elsewhere. This may be because participants used more recent technology (Nucleus 24 rather than Nucleus 22) and received auditory and self-efficacy training as part of their rehabilitation. The results suggest that cochlear implants have a large beneficial effect. They show that social and HRQoL outcomes can be parsimoniously measured using the HPS and AQoL instruments.

Sumario

Este artículo documenta prospectivamente los beneficios de la relaciön calidad de vida/salud (HRQoL) y de la participaciön social en adultos implantados en Australia y Nueva Zelanda. Treinta y cuatro pacientes consecutivos, completaron antes de implantarse el Cuestionario de Calidad de Vida (AqoL) y la Escala de Participaciön Auditiva (HPS) y después, a los 3 y 6 meses de operados. La implantaciön permitiö una mejoría significativa en el AQoL y la HPS. El efecto fue de 1.09 en ambos. Obtuvieron la mejor ganancia quienes estaban en el tercil socio-econömico superior. La HRQoL y los beneficios de participaciön social fueron ligeramente más amplios que los reportados en otros estudios, lo que puede deberse al uso de tecnología más reciente (Nucleus 24 en vez de Nucleus 22) y al entrenamiento auditivo y de autoeficacia que fue parte de la rehabilitaciön. Esto sugiere que los implantes cocleares tienen un efecto benéfico amplio y muestran que los resultados sociales y de HRQoL pueden ser adecuadamente medidos con el uso de la HPS y el AQoL.
