Methods: The EQ-5D survey, which includes a descriptive system and is composed of five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), and the EQ visual analog scale (EQ VAS) were applied to patients with NP.
Results: NP patients (N=1,170; mean age 49±15 yr, 35.5% female) completed the questionnaire. NP patients had a lower EQ VAS score (63.8±21.5; p<0.05) than the general population (71.3). NP patients having some or extreme problems reported higher overall percentages for all EQ-5D domains: mobility (13.3, p<0.05), self-care (8.2, p<0.05), usual activities (26.6, p<0.05), pain/discomfort (55.6, p<0.05), and anxiety/depression (32.6, p<0.05, compared with the general population (10.9, 2.0, 6.4, 25.8, and 13.7, respectively). Mean EQ-5D index values (0.78±0.24) were also lower than the general population (0.89; p<0.05). There were no differences between mean EQ-5D index values when gender, age group, or tobacco consumption were compared.
Conclusions: These results confirm, by using EQ-5D questionnaire, that nasal polyposis has a negative impact on HRQL compared to the general population.
