Towards a consensus on an ICF-based classification system for horizontal sound-source localization
(2022)
The study aimed to develop a consensus classification system for the reporting of sound localization testing results, especially in the field of cochlear implantation. Against the background of an overview of the wide variations present in localization testing procedures and reporting metrics, a novel classification system was proposed to report localization errors according to the widely accepted International Classification of Functioning, Disability and Health (ICF) framework. The obtained HEARRING_LOC_ICF scale includes the ICF graded scale: 0 (no impairment), 1 (mild impairment), 2 (moderate impairment), 3 (severe impairment), and 4 (complete impairment). Improvement of comparability of localization results across institutes, localization testing setups, and listeners was demonstrated by applying the classification system retrospectively to data obtained from cohorts of normal-hearing and cochlear implant listeners at our institutes. The application of our classification system will help to facilitate multi-center studies, as well as allowing better meta-analyses of data, resulting in improved evidence-based practice in the field.
The benefits of cochlear implantation in children with severe hearing impairments are widely known; however, there is no consensus regarding which minimal outcome measurements (MOMs) should be used to determine outcomes in this population with pediatric cochlear implant (CI). Therefore, the authors aim to propose a MOM test battery for pediatric CI recipients that can facilitate international multi-center research and collaboration. A pediatric MOM test battery was developed and agreed-upon by members of the HEARRING group across 30 expert clinics in the field of hearing implantation. The MOM test battery was chosen based on a literature search that focused on outcome measurements applied in clinical trials involving children with a hearing implant. Members of the HEARRING group were then asked to evaluate each of the pediatric MOM tests used. The final pediatric MOM test battery was defined for different chronological age categories (six weeks–18 years) at different suggested test intervals. The test battery includes objective hearing measurements, aided and unaided audiometry, speech perception tests in quiet and in noise, subjective hearing assessments, assessment of language development, and mental and motor development. This study presents a consensus on a MOM test battery for pediatric CI recipients that was agreed upon by members of the HEARRING group. This test battery should allow for international multi-center research to be able to extend and share evidence that will guide future clinical practice and research efforts in pediatric populations with CI.
Purpose
Audiology is an essential service for some patient groups and some interventions. This article sets forth experience-based recommendations for how audiological centers can continue to safely and effectively function during COVID-19.
Methods
The recommendations are the result of panel discussion and are based on the clinical experience of the panelists/authors.
Results
The recommendations cover which patient groups and which interventions should be treated when and whether this can be performed in the clinic or remotely; how to maintain the safety of workplace via optimizing patient flow within the clinic and the sanitation of rooms and equipment; and overcoming communication challenges that COVID-19 intensifies.
Conclusion
For essential audiological services to continue under COVID-19, safety measures must be implemented and maintained, and treatment and communication strategies must be adapted to offset communication difficulties due to personal protective equipment (PPE) and social distancing and to bolster patient confidence. In short, it is vital that staff feel safe, that patients either feel the clinic is safe enough to visit or that remote treatment may be an option, and that clinics and patients have a broad agreement on the urgency of any needed service. We hope that these recommendations help clinics effectively accomplish these goals.
