Managed care dominates healthcare not only in the United States of America but also in the entire planet. It is any system of health delivery which integrates the roles of health insurance as well as the definite delivery of care in which the application and costs of services are managed by means like case management, gatekeeping, and utilization review. In this paper, I will critically analyze the concept of managed care for the kingdom of Saudi Arabia, the advantages and disadvantages of this concept, the healthcare sectors which are highly affected by the managed care, the impacts of managed care on facilities, physicians as well as the patients. Lastly, I will evaluate how managed care is working and being implemented in other countries like the United States of America.
