An integrated knowledge translation experience: Use of the Network of Pediatric Audiologists of Canada to facilitate the development of The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP v1.0).
The goals of this project were: (1) to determine the important factors that influence implementation of evidence-based practice by Canadian audiologists; and (2) to utilize the knowledge-to-action process (Graham et al., 2006) during the development of a guideline for outcome measures to evaluate the auditory development and performance of young children who wear hearing aids, to facilitate clinical uptake and identify barriers to implementation (Bagatto, Moodie & Scollie, 2010; Bagatto et al., 2011; Bagatto, Moodie, Seewald, Bartlett, & Scollie, 2011; Moodie, Bagatto et al., 2011; Moodie, Kothari et al., 2011).
Two projects (Chapters 3 and 4) included the participation of The Network of Pediatric Audiologists of Canada.
The outcome measures guideline to evaluate the auditory development and performance of young children who wear hearing aids is called The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP).
This body of work includes a chapter on knowledge translation and how it can be used to promote the clinical implementation of evidence in audiology (Chapter 3). It also includes three studies: (1) an examination of factors influencing the use of evidence by Canadian audiologists [Chapter 2]; (2) an initial evaluation by the Network of Pediatric Audiologists of Canada of the individual components considered for inclusion in the UWO PedAMP [Chapter 4]; and (3) a final evaluation by the Network audiologists of the released version of the UWO PedAMP and associated training materials [Chapter 5].
Results of the first study indicated that Canadian audiologists rate themselves as competent in finding, evaluating and using research evidence to change practice. Their greatest barriers to evidence-based practice are related to time. By partnering with Canadian audiologists and using the knowledge-to-action framework to guide us (Chapter 4), we were successful in developing the UWO PedAMP guideline into what they rated as being a high-quality, systematic, hearing aid outcome evaluation tool that improves the quality and effectiveness of audiological care received by young children with hearing loss. The results presented in Chapter 5 indicated that the UWO PedAMP is appropriate for clinical implementation, and is recommended by these Canadian audiologists as preferred audiology practice
Protocol for the Provision of Amplification v 2023.01
This Protocol addresses the provision of amplification (hereafter: \u27Amplification\u27) to infants and children who are receiving services from the Ontario Infant Hearing Program (IHP). For the purposes of this protocol, providing amplification includes the processes of prescribing a hearing aid (air or bone conduction) and/or other hearing assistance technologies based on appropriate assessment information, verification that the specified acoustical performance targets have been achieved, fitting the device on the child, and ongoing evaluation of device effectiveness in daily life. Amplification within the IHP does not include the provision of cochlear implants

Fit-to-targets for the desired sensation level version 5.0a hearing aid prescription method for children
Purpose: The purpose of this study was to measure the range of fit to Desired Sensation Level version 5.0 (DSL v5.0) targets in pediatric practice environments. Results will be used in the future to develop clinical-aided speech intelligibility index typical performance data. Method: Clinical partners collected data from 161 final hearing aid settings for children aged †10 years. Measured data were obtained by performing 2-cm coupler-simulated real-ear measurements using the DSL v5.0 implementation on the Audioscan VF-1 (Etymonic Design Inc., Dorchester, ON, Canada) for soft, average, and loud speech inputs and maximum hearing aid output levels. Results: Fittings were within ± 5-dB root-mean-square (RMS) error of target for 77%, 80%, and 82% of fittings for the soft, medium, and loud speech test levels, respectively. Aided maximum power output measures were within ± 5-dB RMS error in 72% of cases. Degree of hearing loss, test frequency, and frequency by test level were significant factors in deviation from target. The range of aided speech intelligibility index values exhibited a strong correlation with the hearing levels of the children tested. Conclusion: This study provides evidence that typical hearing aid fittings for children can be achieved within ± 5-dB RMS error of the DSL v5.0 target. Greater target deviations were observed at extreme frequencies and as the severity of hearing loss increased.
The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP)
This study proposed and evaluated a guideline for outcome evaluation for infants and children with hearing loss who wear hearing aids. The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP) was developed following a critical review of pediatric outcome evaluation tools and was systematically examined by the Network of Pediatric Audiologists of Canada. It consists of tools to gather clinical process outcomes as well as functional caregiver reports. The UWO PedAMP was administered to a clinical population of infants and children with hearing aids. Sixty-eight children were administered the functional outcome evaluation tools (i.e., caregiver reports) a total of 133 times. Clinical process outcomes of hearing aid verification (e.g., real-ear-to-coupler difference) revealed typical aided audibility (e.g., Speech Intelligibility Index). Results for the LittlEARS(Âź) questionnaire revealed that typically developing children with hearing loss who wear hearing aids are meeting auditory development milestones. Children with mild to moderate comorbidities displayed typical auditory development during the 1st year of life after which development began to decline. Children with complex factors related to hearing aid use had lower scores on the LittlEARS, but auditory development was in parallel to norms. Parents\u27 Evaluation of Aural/Oral Performance (PEACH) results indicated no age effect on scoring for children above 2 years of age; however, the effect of degree of hearing loss was significant. This work provides clinicians with a systematic, evidence-based outcome evaluation protocol to implement as part of a complete pediatric hearing aid fitting
An integrated knowledge translation experience: Use of the Network of Pediatric Audiologists of Canada to facilitate the development of the University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP v1.0)
Pediatric audiologists lack evidence-based, age-appropriate outcome evaluation tools with well-developed normative data that could be used to evaluate the auditory development and performance of children aged birth to 6 years with permanent childhood hearing impairment. Bagatto and colleagues recommend a battery of outcome tools that may be used with this population. This article provides results of an evaluation of the individual components of the University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP) version 1.0 by the audiologists associated with the Network of Pediatric Audiologists of Canada. It also provides information regarding barriers and facilitators to implementing outcome measures in clinical practice. Results indicate that when compared to the Parentsâ Evaluation of Aural/Oral Performance of Children (PEACH) Diary, audiologists found the PEACH Rating Scale to be a more clinically feasible evaluation tool to implement in practice from a time, task, and consistency of use perspective. Results also indicate that the LittlEARSÂź Auditory Questionnaire could be used to evaluate the auditory development and performance of children aged birth to 6 years with permanent childhood hearing impairment (PCHI). The most cited barrier to implementation is time. The result of this social collaboration was the creation of a knowledge product, the UWO PedAMP v1.0, which has the potential to be useful to audiologists and the children and families they serve
