Planned Updates to the Leapfrog Hospital Safety Grade Methodology for Fall 2021: Request for Public Comments

Leapfrog is planning four changes to the Leapfrog Hospital Safety Grade methodology that will be used to calculate the fall 2021 Hospital Safety Grades. These updates were made under the guidance of Leapfrog’s national expert panel and research team at Johns Hopkins Medicine and are based on stakeholder feedback. Leapfrog is inviting public comments on these proposed changes through May 31, 2021. Public comments can be submitted using the directions on the first page of the document.

2021 Data Snapshot Dates
The data snapshot date is the date that Leapfrog will extract public data (i.e., download data published by CMS or submitted to Leapfrog or secondary data sources) to calculate Leapfrog Hospital Safety Grades. All data, including Leapfrog Hospital Survey Results, must be finalized by these dates.

  • January 31 (for spring 2021 Safety Grades) 
  • August 31 (for fall 2021 Safety Grades)

Courtesy Review Dates
As a courtesy to hospitals, Leapfrog will hold a Courtesy Safety Grade Review Period before the public release of each Leapfrog Hospital Safety Grade update. The Review Period is an opportunity for hospitals to review the data for accuracy (i.e., identify recording errors, hospital name and address changes, etc.) on a secure website and review changes to the scoring algorithm.

  • February 22 - March 12 (for spring 2021 Safety Grades)

  • Mid-September (for fall 2021 Safety Grades)

Town Hall Calls

Leapfrog hosts a Town Hall Call during the Courtesy Safety Grade Review Period to provide hospitals and other stakeholders with information on changes to the measures and scoring methodology. 

Listen to the March 2, 2021 Town Hall Call recording. View the slides.

Letter Grade Embargo Period 

Following the close of the Courtesy Safety Grade Review Period, Leapfrog finalizes the data and establishes letter grade cut-points. Leapfrog then refreshes the Safety Grade Review website and hospitals are able to participate in a 2-week Letter Grade Embargo Period in which they can preview their letter grade prior to the public announcement.  

  • April 7 - April 28 (for spring 2021 Safety Grades)
  • Mid-late November (for fall 2021 Safety Grades)

2021 Public Announcement Dates 

The Hospital Safety Grades will be updated on the website twice per year.

  • Spring 2021: April 29, 2021

  • Fall 2021: Late November/Early December
