천식 환자에서 전반적 자기 평가와 한국 성인 천식 환자의 삶의 질 평가 설문과의 비교 분석

Abstract

Background: The Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA) is a valid and reproducible tool for evaluating and monitoring Korean adult asthmatics. However, the questionnaire is still burden to some patients, so we developed a simplified global self-assessment scoring.

Objective: The goal of this study is to compare the patient’s global self-assessment scoring method with the QLQAKA and evaluate how it reflects quality of life (QOL) of asthmatics.

Method: One hundred ninety-nine adult asthmatics were enrolled and asked to answer the QLQAKA composed of 17 items in 4 domains (activity, symptom, emotion and exposure to environmental stimuli) and one more global self-assessment question with a 5-point scale was added. According to the Global Initiative for Asthma (GINA) 2006 guide-lines, patients were divided into 3 groups: controlled, partly controlled and uncontrolled groups. Then, we analyzed the relationships between the QLQAKA scores, global self-ssessment scores and various clinical parameters.

Result: The mean QLQAKA score and global self-assessment score were statistically significantly different between the 3 groups. Pulmonary function tests were also statistically significantly different between the 5 QLQAKA score subgroups as well as 5 self-assessment score subgroups. Moreover, global self-assessment scores were well correlated with QLQAKA scores.

Conclusion: In a busy outpatient clinic, we may estimate the QOL of asthma patients using a simplified patient’s global self-assessment scoring method.
