Client Oriented Scale of Improvement
Also written as: COSI — Client Oriented Scale of Improvement
A patient-centred outcome measure in which individuals nominate up to five personal listening goals and rate their performance and satisfaction after hearing intervention.
Full Definition
The Client Oriented Scale of Improvement (COSI) was developed by Dillon, James, and Ginis (1997) and is widely used in aural rehabilitation to capture goal-specific outcomes that are meaningful to the individual patient. The client nominates specific listening situations they wish to improve, and the clinician categorises each goal into one of 16 needs categories. At follow-up, the patient rates both their ability in that situation and their satisfaction with the achieved change. COSI data are considered patient-reported outcomes (PROs) and must be reported accurately in research manuscripts, with the category labels preserved as standardised headings.
Usage
Usage note: Acronym pronounced as a word: 'KOH-zee'. Do not confuse with the HHIE or IOI-HA, which are generic rather than goal-specific outcome measures.
