Improving Quality Health Care Services by Implementing DMAIC Approach in Paediatric Cardiology Department of Public Hospital of Sindh, Pakistan: A Case Study

Objectives: The hospital industry has changed its dimension from diagnosis to complete total patient satisfaction. This study aims to identify the critical variables that can enhance overall patient satisfaction in the hospital industry. The study identified three critical factors for any hospital to provide quality service. Methodology: The study adopted the lean Six Sigma process improvement methodology to identify the critical service factors in hospitals. Lean Six Sigma is a flexible problem-solving tool that comprehensively solves any problem. DMAIC process improvement methodology is used to define, measure, analyze, improve, and control the overall experience in the hospital. CTQ (critical to quality) was defined and represented by Kano methodology. After filtration through cause and effect analysis, three core dimensions and 25 sub-dimensions of critical quality were identified. The impacts of these 25 sub-dimensions were evaluated and prioritized using the Kano Model of patient satisfaction. This identifies the most critical service requirement. This study is an initiative for service quality improvement in the hospital industry. In the future, this technique can be modified and adopted by different public and private hospitals to enhance the practical implementation. Results: Findings indicate that healthcare organizations demonstrate enhanced system-wide capabilities, optimizing resource utilization. Understanding patient needs propels satisfaction and delight. Three overarching factors, with 25 sub-factors, significantly impact patient satisfaction, predominantly yielding positive effects across the categories. Conclusion: This research concludes that providing quality service is critical in the hospital industry. Quality service is pivotal in the evolving hospital industry, transitioning from a focus on diagnosis to holistic patient satisfaction. This study aims to identify critical variables essential for enhancing overall patient satisfaction, pinpointing key factors crucial for delivering quality service in any hospital.
