How does chronic back pain influence quality of life in Koreans: A cross-sectional study

Abstract

Study design: A cross-sectional study.

Purpose: To explore the impact of chronic low back pain (CLBP) on individuals' quality of life; to understand current treatment practices and level of satisfaction with treatment in patients with CLBP.

Overview of literature: Assessing subjective, patient-reported outcomes such as quality of life is essential to health care research.

Methods: Influences of the CLBP were analyzed via a questionnaire, which contained the character of CLBP, effect of pain management, Korean version Oswestry Disability Index (K-ODI) and Korean version of 12-item Short Form Health Survey (SF-12v2).

Results: Of 3,121 subjects who responded, 67.3% had moderate to severe pain; 43.5% presented prolonged CLBP of more than two years; and 32.4% had suffered from sleep disturbance due to pain. 22.8% of the patients were not satisfied with current pain management. The mean K-ODI score was 37.63; and it was positively correlated with the mean pain intensity (r=0.6, p<0.001). The SF-12v2 result was negatively correlated with mean pain intensity (PCS: r=-0.5, p<0.001;

Mcs: r=-0.4, p<0.001) and also negatively correlated with the K-ODI score (PCS: r=-0.75, p<0.001;

Mcs: r=-0.5, p<0.001). The conformity between patients and doctors in pain assessment was fair (κ=0.2463).

Conclusions: CLBP negatively affects quality of life. Of total 22.8% of the patients were not satisfied with current pain management. Such needs to be taken more seriously by doctors for improvement of satisfaction and quality of life in patients with CLBP.
