In the context of CMS, what is the primary focus of performance scores?

The primary focus of performance scores within the context of CMS (Centers for Medicare & Medicaid Services) is to gauge and enhance healthcare quality. Performance scores are part of various programs, such as the Quality Payment Program and value-based purchasing initiatives, which aim to assess how well healthcare providers deliver care.

These scores typically evaluate a range of factors including patient outcomes, the effectiveness of treatments, patient satisfaction, and adherence to clinical guidelines. By focusing on these elements, CMS aims to improve the overall quality of care that patients receive while incentivizing providers to meet certain quality benchmarks. This approach aligns with the overarching goal of transitioning from volume-based to value-based care, where the quality of services provided is prioritized over the quantity.

In contrast, other options do not capture this focus. Rewarding high patient volumes relates more to quantity rather than quality. Decreasing treatment costs is certainly a consideration in healthcare reform, but it is usually a secondary effect or goal compared to ensuring the quality of care. Limiting patient choices in providers is contrary to the objectives of CMS, which seeks to empower patients and provide them with options for their care. Hence, the focus on enhancing quality is why the correct answer stands out as the most aligned with CMS objectives.
