Background Access to healthcare in the Kingdom of Saudi Arabia (KSA) has indeed seen significant improvements over the last three decades. These advancements have, however, posed challenges for healthcare organizations, their personnel, and other stakeholders. The need to enhance the quality of healthcare services has become increasingly evident. The ambitious Saudi Vision 2030 and the National Transformation Program 2020 (NTP) have made healthcare a central focus area. These challenges include: increasing demand for healthcare services coupled with a rise in costs, changing patterns of disease, shortage of healthcare professionals, a significant annual pilgrim population, a rise in medical errors and long waiting times. A key policy being implemented as a part of the development plan in KSA of the Saudi Vision (2030), with regard to health services, is the need to adopt methods to improve quality of care, and to apply these methods across all health sectors to ensure that appropriate levels of efficiency and quality are achieved. Indeed, measurement of patient satisfaction is central to identifying areas for improvement and thus achieving optimal delivery of healthcare services. In addition to patient satisfaction, it is important to consider access to healthcare as a fundamental quality of care indicator. Aim of the study: This study aims to assess the effect of service quality of health care in Saudi Arabian on patient satisfaction with respect to primary health care services in Makkah in 2022.
