Quality of Life and Quality of Sleep among Post CABG Patients

Introduction: Coronary artery bypass grafting (CABG) surgery is one among the most common procedures performed in the world, and it is one of the possible treatments for coronary artery disease (CAD). A study to assess the quality of life and quality of sleep among post coronary artery bypass grafting (CABG) patients was done in Amrita Institute of Medical Science, Kochi. Objectives of the study were to (1) identify quality of life among post CABG patients (2) identify the quality of sleep among post CABG patients (3) find out the correlation between quality of life and quality of sleep among post CABG patients (4) Find the association between quality of life and selected demographic variables among post CABG patients (5) Find the association between quality of sleep and selected demographic variables among post CABG patients.

Methodology: A quantitative approach with a descriptive correlational design using a non-probability convenience sampling technique was used to collect data from 101 post CABG patients. The setting used for the study was CVTS OPDs at AIMS, Kochi. A standardized quality of life questionnaire and quality of sleep (Pittsburgh sleep quality index) tool was used for the assessment along with a semi-structured questionnaire to assess socio-demographic and clinical data.

Results: The study result showed that the majority of samples (97%) had good QOL with mean score of 69.22. PCS (96%) showed higher value than MCS (68.3%). Considering sleep 61.4% expressed good quality of sleep. There was a significant weak negative correlation between QOL and quality of sleep (r = -0.246). Hence as QOL increases and quality of sleep increases. Also a significant association found between QOL and socio-demographic variables like occupation (p=0.018), association between sleep and socio demographic variables like occupation (p=0.05).

Conclusion: Overall QOL and quality of sleep improved after CABG.
