1. What is the study about and why is it important?
Single Sided Deafness (SSD) refers to the condition where there is normal or near-normal hearing in one ear and a severe to profound hearing impairment in the other ear.
Good hearing in both ears is important for everyday listening tasks such as understanding speech in noisy environments, locating where sounds are, and identifying threats such as oncoming traffic.
Researchers don’t yet agree on what benefits and harms (known as ‘outcomes’) should always be assessed when evaluating whether or not an intervention for SSD is effective. These inconsistencies hinder progress to find the most effective intervention.
The CROSSSD Study group will work closely with patients and professionals across the world who are all experts in Single Sided Deafness. We will find agreement on what outcomes are critical and important to measure when evaluating interventions for SSD.
2. Study duration
This project will be completed by October 2022.
3. What does it involve?
The CROSSSD study is supported by the NIHR Nottingham BRC and follows methods developed by the COMET initiative (MRC North West Hub for Trials Methodology).
Identifying appropriate outcome domains is crucial when designing clinical trials to evaluate the effects of different interventions.
The selected outcomes need to be important to key stakeholders such as patients, healthcare professionals or budget holders in order to minimise bias when making decisions about healthcare.
