The relationship between subjective assessment instruments in chronic rhinosinusitis

Area of Science:

• Otolaryngology
• Rhinology
• Quality of Life Research

Background:

• Chronic rhinosinusitis (CRS) assessment relies on subjective measures.
• Understanding the correlation between disease severity and quality of life (QoL) is crucial for patient management.

Purpose of the Study:

• To establish an evidence-based definition for the relationship between CRS severity instruments: visual analogue scale (VAS) and mild, moderate, severe (MMS) classification.
• To determine the threshold at which CRS impacts a patient's QoL.

Main Methods:

• 116 CRS patients completed questionnaires assessing disease severity via VAS and MMS classification.
• Patients also reported on whether their QoL was affected by the condition.

Main Results:

• Statistically defined ranges for MMS on the VAS: Mild (0-3), Moderate (3-7), Severe (7-10).
• QoL was perceived as affected in patients with VAS scores of 5 or higher (IQR 5.10-8.68).
• Higher MMS categories correlated with greater QoL impact: 30.3% (Mild), 79.6% (Moderate), 97.4% (Severe).

Conclusions:

• A validated definition for correlating MMS and VAS in CRS is proposed.
• A VAS score of 5 or more is proposed as a general indicator for QoL impairment in CRS patients.
