Learning Objective 1: The learner will be able to understand the predictors of health related quality of life (HRQOL) in patients with chronic obstructive pulmonary disease (COPD).
Learning Objective 2: The learner will be able to prepare effective care plan when provide nursing interventions to enhance the HRQOL in patients with COPD.
The purpose of this study was to identify the factors associated with health related quality of life (HRQOL) in patients with COPD in South Korea.
l Methods
This study was a descriptive survey design. The participants were 245 outpatients with COPD at 6 general hospitals in South Korea. The data was collected from March 1 to November 31 of 2010. St. George’s Respiratory Questionnaire (SGRQ) was used for the evaluation of HRQOL with patient of COPD. The data were analyzed by percentages, means, t-test, ANOVA, Pearson correlation and multiple regression using SPSS WIN 18.0 program.
l Results
The total mean score (SD) for HRQOL was 36.04(19.43), at each subscale, ‘symptom’ was scored 35.72(20.96), ‘activity’ and ‘impact’ was measured 53.46(25.10), and 26.20(20.84) respectively. There was a positive correlation among age (r=.12, p=.037), gender (r=.11, p=.040), education level (r=-.20, p=.001), total monthly family income (r=-.23, p<.001), duration of diagnosed as COPD (r=.19, p=.001), FEV1 % predicted (r=-.34, p<.001), dyspnea (r=.65, p<.001), sleep disturbance (r=.37, p<.001), and physical activity (r=-.20, p<.001). In multivariate approach, most significant predictors of HRQOL was dyspnea (β=.53) and this regression model explained 47% of variance in HRQOL(F=23.029, p<.001).
l Conclusion
The findings of this study reveal that dyspnea was the most significant predictors of HRQOL in patients with COPD. Therefore, nurses should design the nursing intervention program for treat dyspnea to enhance the HRQOL for patients with COPD.
