Background: Coronary Artery Bypass Graft (CABG) surgery is a vital procedure for patients with severe coronary artery disease; however, post-operative complications, prolonged hospital stays, and readmissions are common challenges, and Total Quality Management (TQM) is a structured approach aimed at improving healthcare processes and outcomes. Methods: This study was conducted in a hospital setting, comparing 100 CABG patients before and after TQM implementation, with key outcome metrics including average length of hospital stay, readmission rate, post-operative infection rate, mortality rate, and patient satisfaction scores, while hospital performance metrics such as surgery start time delays, operating room turnover time, staff compliance with checklists, ICU bed occupancy, and best practices in post-operative care were also measured, and statistical analysis was conducted to assess the percentage improvement across these variables. Results: TQM implementation led to significant improvements in patient outcomes, as the average hospital stay decreased by 21%, readmission rates dropped by 43.3%, post-operative infection rates were halved, mortality rates fell by 40%, and patient satisfaction scores increased by 26.2%; additionally, in terms of hospital performance, surgery start time delays were reduced by 50%, operating room turnover time improved by 33.3%, staff compliance with pre-surgery checklists rose to 95%, ICU bed occupancy dropped by 16.7%, and best practices in post-operative care increased by 31.4%, underscoring the positive impact of TQM on hospital efficiency and patient care.

Conclusion: Implementing TQM in CABG patient care significantly improved clinical outcomes and operational efficiency, as reductions in hospital stay length, infection rates, and mortality, alongside improved staff compliance and patient satisfaction, demonstrate the value of adopting TQM in cardiac surgery settings, and this study highlights TQM’s potential to optimize CABG care, contributing to enhanced patient safety and resource management.
