Patient satisfaction is a critical indicator of healthcare quality, reflecting patients’ perceptions of care and the effectiveness of healthcare delivery. Despite its recognized importance, inconsistencies in survey design, application, and integration across diverse healthcare systems present challenges for standardization and actionable use. High income countries often employ validated, culturally adapted instruments, whereas middle- and low-income nations face infrastructural, methodological, and cultural barriers, limiting comparability and the effectiveness of quality improvement initiatives. Although patient-reported experience measures (PREMs) and patient-reported outcome measures (PROMs) have gained attention for capturing comprehensive patient-centered perspectives, there remains a gap regarding their systematic application for measurable healthcare improvements. This review aimed to summarize current research on the role of patient satisfaction surveys in quality improvement, identify methodological and contextual gaps, and highlight strategies for maximizing survey utility in patient-centered care. A systematic search of peer-reviewed studies published between 2015 and 2025 was conducted across PubMed, Google Scholar, Science Direct, and Springer Link, applying thematic analysis to 15 selected studies. Findings indicate that determinants of satisfaction include communication quality, waiting times, environmental factors, professional competence, and socio-demographic influences. Integrating patient feedback into continuous quality improvement frameworks, digital platforms, and specialty-specific instruments enhances care responsiveness, engagement, and outcomes. However, disparities in methodology, cultural adaptation, and digital integration persist. Strengthening survey validity, embracing technology, and standardizing cross-national measures are essential for translating patient experiences into sustainable healthcare quality improvements worldwide.
