Using of the World Health Organization quality of life instrument, short form to patient after PCI or CABG surgery

Abstract

OBJECTIVES: This investigation aimed to estimate reliability of the WHOQOL-BREF questionnaire and quality of life of patients after PCI or CABG surgery. METHODS: In this cross-sectional study, 268 patients after PCI or CABG surgery were studied in East Kazakhstan and Pavlodar regions of Kazakhstan from September to December 2019. The Russian version of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) was used to measure their quality of life. Cronbach’s alpha coeffi cient, Pearson’s correlation coeffi cient, paired t-test, independent t-test, and linear regression model were used to analyze the data. RESULTS: The mean age of the participants was 60.8 ± 9.2 years, while most of them were male (75.0 %). The overall observed Cronbach’s alpha coeffi cient for the WHOQOL-BREF was 0.842, ranging from 0.668 to 0.764 in its four domains. The total mean score of the respondents on the WHOQOL-BREF was 13.97. The highest and lowest mean scores were observed in the environmental domain (15.22) and the physical health domain (13.00), respectively. CONCLUSIONS: The WHOQOL-BREF questionnaire has a good reliability in characterizing the quality of life of patients after PCI or CABG surgery. Patients after PCI or CABG surgery had a relatively moderate quality of life (Tab. 6, Ref. 23). Text in PDF www.elis.sk
