Dataset: Inpatient Rehabilitation Facility Compare (IRF Compare)

Basic Information
Dataset Full Name Inpatient Rehabilitation Facility Compare
Dataset Acronym IRF Compare
Summary The Inpatient Rehabilitation Facility Compare (IRF Compare) is a facility level database developed and monitored by the Centers for Medicare and Medicaid Services (CMS). Its purpose is to provide quality of care measures for inpatient rehabilitation facilities. Data are collected from Medicare claims and Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI) file as well as the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) tool.

Note that patient level data are not available. All data are aggregated at the national, state and specific Inpatient Rehabilitation Facility level.
Key Terms Inpatient Rehabilitation Facility, Healthcare-acquired infections, Functional Outcomes, Unplanned Hospital Readmission, Quality of Care Outcomes
Study Design Longitudinal
Data Type(s) Administrative
Sponsoring Agency/Entity Centers for Medicare and Medicaid Services (CMS), Department of Health and Human Services (HHS)
Health Conditions/Disability Measures
Health Condition(s) NA
Disability Measures NA
Measures/Outcomes of Interest
Topics State and regional variations in IRF quality outcomes.
Quality outcomes, healthcare associated conditions and infections, unplanned readmissions.
Hospital readmission, urinary tract infection, pressure ulcers

Geographic Coverage National
Geographic Specificity Individual Inpatient Rehabilitation Facilities
Data Collection
Data Collection Mode Administrative claims data
National Healthcare Safety Network (NHSN) tracking system
Years Collected January 2015 - present
Data Collection Frequency Quarterly

Strengths and Limitations
Strengths Data ideal for performing research on regional and state variation on quality outcomes.
Data can be linked with other Medicare and CMS datasets.
Potential for longitudinal analysis as additional time periods are incorporated.
Limitations Patient-level data not available.
Data based on Medicare participating agencies only, not necessarily representative of all inpatient rehabilitation facilities.
As of February 2017 several quality outcomes not yet available, therefore research use is currently limited.
