Enhancing Healthcare Service Quality: A Systematic Review of Interventions and Patient-Centered Outcomes

Abstract

: Improving healthcare service quality is essential for enhancing patient outcomes, satisfaction, and system efficiency. This systematic review synthesizes recent evidence on interventions aimed at improving healthcare quality and their impact on patient-centered outcomes. A structured search was conducted across major databases, following PRISMA 2020 guidelines, covering studies published between 2016 and 2025. Included studies examined interventions such as Lean and Six Sigma methodologies, digital health technologies (e.g., telemedicine and artificial intelligence), and patient-centered care models. The findings indicate that integrated approaches combining process optimization with patient engagement significantly improve service delivery, reduce waiting times, and enhance patient satisfaction. Digital interventions further contribute to improved access and care coordination. However, variations in study design and outcome measures limit comparability across settings. The review highlights the importance of adopting multi-dimensional strategies that integrate organizational, technological, and human-centered approaches to achieve sustainable improvements in healthcare service quality..
