Long Term Impact of ‘Risk Factors for Permanent Childhood Hearing Impairment’ on Quality-of-Life Outcomes in Cochlear Implant Recipient Children
摘要
Cochlear implantation (CI) is used in treatment of children with bilateral severe to profound sensorineural hearing loss. Lately, due to technological progress, increasing number of children are undertaking CI. Children with risk factors for permanent childhood hearing impairment (PCHI) also undergo CI. ‘Risk factor for PCHI’ may have an effect on CI outcomes. The aim of this study was to determine the long term impact of ‘Risk factor for PCHI’ on CI outcome. Objective of this study was to measure the long-term impact of ‘risk factor for PCHI’ on Health Related Quality of Life (HRQoL) outcome post-CI in order to provide optimal counseling to families of CI candidates. In this prospective study at a tertiary care centre, we evaluated 75 CI recipient children from 2011 to 2018. Group A consisted of 50 (66.7%) children with absent ‘risk factor for PCHI’ and Group B with 25 (33.3%) children had presence of ‘risk factor for PCHI’. Following CI, all children received auditory-verbal therapy and thereafter we measured their long-term HRQoL outcomes at 5 years post-CI. Children were assessed by Nijmegen Cochlear Implant Questionnaire (NCIQ) & Children with cochlear implants: parental perspectives-questionnaire (CCIPPQ). There were significantly better mean HRQoL outcomes (increase of 13.3% in mean NCIQ and 14.5% in mean CCIPPQ scores) in CI recipients at 5 years post-CI with absence of ‘risk factor for PCHI’ as compared to those with presence of ‘risk factor for PCHI’ [P value < 0.05 for both the mean NCIQ scores & mean CCIPPQ scores respectively]. However, for children with presence of ‘risk factor for PCHI’, mean NCIQ & CCIPPQ scores were still greater than 75% of maximum achievable NCIQ & CCIPPQ scores. In this study, CI recipient children who were implanted with absence of ‘risk factor for PCHI’ were found to have significantly improved HRQoL outcomes at 5 years post-CI. Hence, there seems to be improved outcomes with CI with absence of ‘risk factor for PCHI’. However, even in children who received CI with presence of ‘risk factor for PCHI’, there was a considerable improvement in HRQoL outcomes and CI was still efficacious in these children. Hence, study of ‘risk factor for PCHI’ may provide tenable aid in predicting the HRQoL outcomes and optimal counseling to parents & families of CI candidates.
