Which of the following variables does not influence the rating of health care systems?

Regulatory compliance is the correct choice because, while it is an important aspect of health care systems, it does not directly influence the ratings of health care systems in the same way that cost, quality, and access do. Ratings typically focus primarily on how these three components affect the overall experience and outcomes of care for patients.

Cost refers to the financial barriers that patients face when accessing health care, which greatly impacts their experience and satisfaction. Quality encompasses the effectiveness and efficiency of the care provided, influencing patient outcomes and perceptions about the health care system. Access addresses the availability of services and the ease with which individuals can obtain care, which is crucial for health system evaluations.

In contrast, regulatory compliance involves ensuring that health care providers adhere to laws and regulations but does not itself assess the effectiveness or performance perceived by consumers. While compliance is essential for the functioning of a health care system, it is more of a foundational requirement than a direct influencer of system ratings. Thus, it does not play the same role in shaping patient experiences in the rating process.
