Dataset: Swing Bed Assessment-Minimum Data Set (SB-MDS)

Basic Information
Dataset full name: Swing Bed Assessment-Minimum Data Set
Dataset acronym SB-MDS
Summary Swing Beds are rural skilled nursing facilities (SNF) or Critical Access Hospitals (CAH) participating in Medicare that are approved by CMS to provide post-acute skilled nursing services. The Swing Bed-Minimum data set (SB-MDS) is a subset of the Minimum Data Set (MDS) containing patient-level assessments for those admitted to “swing beds”. The data is primarily collected using a two page assessment form and only includes items required for reimbursement purposes, ongoing analysis of swing bed utilization under the SNF-PPS (prospective payment system), and tracking patient readmissions. Primary and comorbid condition “active diagnosis” information from claims files is also included. The SB-MDS includes patient-level demographic, clinical and facility-level information.
