Staffing shortages, outdated equipment, and stretched-thin programs—without the resources to meet the high bar set by CMS, hospitals face lower reimbursement rates from Medicare and Medicaid, the programs many of their patients rely on.

It's a cycle that traps hospitals in a struggle to deliver the quality care they desperately want to provide. But what if there was a solution that boosted star ratings and improved the lives of healthcare workers and patients alike?

What Is The CMS Star Rating System?

The Centers for Medicare & Medicaid Services (CMS) oversees federal Medicare and Medicaid programs. These plans provide health insurance to millions of Americans, and hospitals that treat these patients rely heavily on their funding.

To ensure quality care, CMS implemented the star rating system. It functions as a performance review, using a simple 1 to 5-star scale.

The star rating is useful for many systems, but two that impact hospitals are the Overall Hospital Quality Star Rating and the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS).

1. Overall Hospital Quality Star Rating

This rating is based on 46 quality metrics reported by hospitals to CMS, encompassing five weighted areas:

  1. Mortality (22%): How often patients die in the hospital
  2. Safety of Care (22%): How often complications happen during procedures
  3. Readmission Rates (22%): How often patients return to the hospital within 30 days
  4. Patient Experience (22%): How satisfied patients are with their stay
  5. Timely and Effective Care (12%): How quickly and appropriately patients receive specific treatments

Hospitals gather this information from electronic health records, admission and discharge data, and coded diagnoses and procedures. But, the specific timeframe may vary. For example, the information for the July 2023 ratings came from January 2023, and a re-released measure in April 2023.

Hospitals report their details through programs like the Hospital Inpatient Quality Reporting (IQR) Program, which CMS analyzes to calculate the Overall Hospital Quality Star Rating.

These weights add up to 100% and determine a hospital's average score. If they don't have data for a specific area, CMS makes adjustments to account for it in the calculation.

2. HCAHPS Rating

The CMS gauges patient satisfaction through a standardized survey—HCAHPS. This helps them with valid comparisons and empowers patients to choose hospitals based on their experience. The sampling protocol ensures consistent data collection, capturing representative patient perspectives.

HCAHPS isn't necessarily focused on treatment results but on the patient's experience during their stay.

Hospitals select participants through a random monthly sampling of all eligible patient discharges. They can do it throughout or at the end of the month, ensuring a representative sample for accurate feedback.

They collect data via:

  • Mail
  • Telephone
  • Mail with telephone follow-up
  • Interactive voice response

They collect feedback on aspects like:

  • Communication
  • Responsiveness
  • Pain management
  • Information transparency
  • Hospital environment
  • Overall experience

To be eligible for HCAHPS star ratings, hospitals must have at least 100 surveys in a 12-month reporting period. While 100 qualifies them, the goal is for them to achieve at least 300 over the same period to ensure more statistically reliable data for the star ratings.

The star ratings for both metrics are publicly available on the Medicare.gov website. This makes it easy for patients to choose which hospitals best suit their needs.

Why Is It Important for Healthcare Providers?

The US healthcare system has a mix of public—Medicare and Medicaid—and private insurance. Hospitals that treat many patients who rely on the former need government funding.

The CMS star rating system directly impacts the organization's financial health and market position for several reasons:

Financial Security

Those with high CMS star ratings can qualify for better reimbursement rates from Medicare and Medicaid. High-performing hospitals might receive money per procedure compared to the base rate.

Higher reimbursement rates can help hospitals invest in better equipment, technology, and staff and improve overall care quality.

Market Advantage

Regardless of insurance type, patients are increasingly using these ratings to compare hospitals when making healthcare decisions. A high rating signifies trust and confidence in the quality of care, as indicated by previous patients.

Insurance carriers—like Humana and Blue Cross Blue Shield—also evaluate hospital CMS ratings when deciding on preferred providers. Hospitals with high scores are more likely to be included in these networks, offering patients more comprehensive access and lower out-of-pocket costs.

For physicians, these ratings signify expertise, efficient care, and patient focus. Referring patients to such facilities fosters confidence in quality, potentially leading to better outcomes, fewer complications, and lower costs.

Quality Improvement

Standardized metrics ensure fair comparisons across hospitals, enabling them to assess their performance relative to a national benchmark. With this knowledge, healthcare organizations can research and implement alternative strategies to improve their quality of care.

Strategies to Boost Hospital Star Ratings

Hospitals serving a high volume of Medicaid and Medicare patients often face challenges that can lower their CMS star ratings. These difficulties—like readmissions—often tie into socioeconomic or income-related factors and can't be solved through generic one-size-fits-all advice.

Luckily, there's a powerful resource: data. By analyzing clinical outcomes and patient surveys, healthcare organizations can pinpoint specific weaknesses. This analytical approach can help develop targeted care strategies that effectively address the specific needs of their patient population.

Case Study

For example, a hospital with 300 beds can struggle with a disorganized approach to clinical resources. Guidelines and protocols may be scattered across different departments, servers, and even personal computers. This can lead to inefficiencies and inconsistencies in patient care.

We can solve the issue by creating a centralized knowledge base for all clinical resources. The hospital can upload all existing protocols, guidelines, and best practices into the platform like C8 Health.

Learning From Success Stories

Healthcare organizations can leverage valuable insights from high-performing facilities in their region. The Hospital Compare tab lets you filter by star rating and location, making it easy to identify the ones serving similar patient demographics and challenges that have achieved higher scores.

This could involve examining staffing models, patient engagement strategies, or the use of technology to streamline guidance and follow-up care. By researching their practices and programs, you can gain valuable ideas to adapt and implement in their own settings.
