Validation of the Patient-Reported Outcome Measures Tool "Catquest" in Odia Language

Area of Science:

• Ophthalmology
• Health Services Research

Background:

• Patient satisfaction is increasingly important in healthcare, alongside objective surgical outcomes.
• Quality of vision after cataract surgery can be evaluated using daily activity questionnaires.
• Local language questionnaires improve patient-doctor interaction.

Purpose of the Study:

• To validate the Catquest questionnaire for assessing quality of life in Odia-speaking patients undergoing cataract surgery in Eastern India.

Main Methods:

• A prospective study involving 40 patients undergoing cataract surgery.
• Translation and validation of the English Catquest questionnaire into Odia.
• Administration of both Odia and English questionnaires pre- and post-surgery.
• Statistical analysis using Intraclass Correlation Coefficient (ICC) to assess reliability and agreement between languages.

Main Results:

• The Odia Catquest questionnaire demonstrated perfect reliability (ICC=1) for activities like reading, mobility, and hobbies post-surgery.
• Good reliability was observed for activities including price checking, needlework, and shopping.
• Initial pre-operative low ICC for television viewing indicated inconsistency, which resolved post-surgery, showing improved comfort and no variability.

Conclusions:

• The validated Odia Catquest questionnaire is a reliable tool for assessing patient-reported outcomes in daily activities post-cataract surgery.
• The questionnaire is well-applicable in clinical settings and can be successfully incorporated into practice.
• Using localized questionnaires like the Odia Catquest enhances the assessment of subjective parameters crucial for procedure success.
