The development and implementation of the Nottingham early cognitive and listening links (Early CaLL); A framework designed to support expectation counselling and to monitor the progress, post cochlear implantation, of deaf children with severe (SLD) and profound and multiple learning difficulties (PMLD) and associated complex needs

Objectives: Appropriate outcome measures are required for deaf children with severe (SLD) and profound and multiple learning difficulties (PMLD). This paper describes the development and structure of the Nottingham Early CaLL Framework and via a series of case-studies, demonstrates its effectiveness in tracking progress over time.Methods: The materials were developed in-house in 2011-2012 and refined through the exploration of established approaches in health and education, an inter-rater reliability study and an extended pilot of the draft materials.Results: The Framework quantifies the long term benefit of cochlear implantation by recording the amount of functional sound processor use achieved, alongside incremental changes in auditory behaviours, in the context of cognition, interaction and communication development. The case-studies demonstrate how it can provide evidence of measurable changes and help to explain some of the underlying reasons for the range of long-term outcomes.Discussion: Within this population, the key predictive, within-child factors of post cochlear implant listening and spoken language outcomes, are an individual's cognitive and physical capacities and their engagement in social communication.Conclusion: The Early CaLL Framework supports expectation counselling and decision-making in the assessment phase and post cochlear implantation provides monitoring tool, which encourages collaboration between families and professionals.

Development and validation of the Nottingham Auditory Milestones (NAMES) profile for deaf children under 2 years old, using cochlear implants

OBJECTIVES

Clinicians face considerable challenges in setting appropriate auditory goals for babies and young children who receive cochlear implants. This paper describes the rationale, organization, implementation, and validation of the Nottingham Auditory Milestones profile that was developed to address these challenges.

METHODS

The use of the profile has been fully integrated into the postoperative pathway at the Nottingham Auditory Implant Programme since 2009. Data are presented on a cohort of 30 children who received bilateral cochlear implants under the age of 2 years and who have no other diagnosed difficulties. The data were used to validate the profile's structure and characterize the expected development trajectory for this population of children.

RESULTS

The analysis of routine data from the children confirmed that the profile's structure reflected the typical order and rate at which skills emerged and were acquired over the first 3 years following cochlear implantation. The distribution of profile scores across five assessment time-points established a developmental trajectory for typically developing children. Three case studies describe the use of the profile to set consistent expectations for progress for a wide range of children.

DISCUSSION

The development trajectory established using the profile provides a mechanism to identify children not making the expected progress, in order to support the need for a review of approach or a differential diagnosis.

CONCLUSION

The Nottingham Auditory Milestones profile is an accessible and practical tool for identifying, monitoring, and appraising the auditory achievements of deaf babies and young children in the first 3 years following cochlear implantation.
