Recognition

We use ratings and rankings by outside organizations to identify opportunities for improvement that align with our primary goal of ensuring the best patient outcomes.

Newsweek named Cleveland Clinic the No. 2 hospital in the world for the fifth straight year in its “World’s Best Hospitals 2023” report. Cleveland Clinic Abu Dhabi, Fairview Hospital and Weston Hospital also were recognized among the top 250 hospitals out of more than 2,300 hospitals worldwide.

Cleveland Clinic is a trusted healthcare leader. We're recognized in the U.S. and throughout the world for our expertise and care.

The Leapfrog Group grades hospitals on patient safety. In fall 2023, eight of our U.S. hospitals earned an A grade, three earned a B, three received a C and two received a D.

The Centers for Medicare & Medicaid Services (CMS) rates hospitals on care quality, safety and patient experience. Five of our U.S. hospitals received the maximum five stars in the CMS Overall Hospital Quality Star Rating in 2023. These results contributed to our most successful year to date in the CMS quality pay-for performance programs.

Vizient ranks U.S. hospitals on quality and value. Three of our U.S. hospitals received top decile performance in their cohort in 2023 — our main campus, Fairview Hospital and Union Hospital. Twelve of our hospitals showed improved performance in 2023.

The American Nurses Credentialing Center, a subsidiary of the American Nurses Association and the largest and most prominent nursing credentialing organization in the United States, established the ANCC Magnet Recognition Program^® in 1994. Research has shown that patient care outcomes are better at Magnet hospitals, where there is an environment that empowers nurses, values their contributions and supports nursing leadership. Magnet status is awarded for a four-year period, after which hospitals must apply again for the recognition. Twelve hospitals within Cleveland Clinic have achieved Magnet status. The ANCC Pathway to Excellence Program^® is earned by healthcare organizations that create a positive nursing practice environment where nurses’ needs are supported and high clinical standards are promoted. Pathway to Excellence^® status is bestowed for a four-year period, after which hospitals must apply again for the recognition. Three hospitals within Cleveland Clinic are Pathway to Excellence^® designated.

• Development of coronary angiography to reveal artery blockages (1958).
• Establishment of cadaver donor use in kidney transplants (1963).

Research & Education

For more than 100 years, Cleveland Clinic has advanced its mission through researching health and educating caregivers of the future.

Treatment Outcomes

Measurable Quality

Putting patients first demands a relentless focus on measurable quality. By setting standards, collecting data and analyzing results, Cleveland Clinic puts patients first through improved outcomes and better service, providing a healthier future for all.

Group Practice Model

Cleveland Clinic is structured as a group practice. The doctors on staff are salaried employees and are not in private practice. They pool their wisdom and expertise for the benefit of the patient and the community.

In 2007, we restructured our practice to complement the group practice model. By combining specialties surrounding a specific organ or disease system into integrated practice units called institutes, we can better provide collaborative, patient-centered care.

Clinical Expertise

Cleveland Clinic is organized by institutes, which align medical care in a way that is more easily understood by patients.
