Dataset: Home Health Compare (HHC)

Basic Information
Dataset full name: Home Health Compare
Dataset acronym HHC
Summary The Home Health Compare (HHC) database contains home health agency level data. It is designed to allow patients and their caregivers the ability to compare home health agencies on outcome measures and process of care measures. The Home Health Compare datasets include a subset of Outcome and Assessment Information Set (OASIS) based quality performance measures collected by the Centers for Medicare and Medicaid Services (CMS). Data are collected from summarized patient assessments and Medicare claims.

Note that no patient level data is available. All data is aggregated at the national, state and individual Health Care agency levels.
Key Terms Home Health Agency Performance, Quality of Patient Care, OASIS, Health Care Utilization, Home Health Consumer Assessment of Healthcare Providers and Systems (HHCAHPS), Patient satisfaction with home health care, home health care, national outcomes, state outcomes.
Study Design Longitudinal
Data Type(s)
Sponsoring Agency/Entity Centers for Medicare & Medicaid Services (CMS); Department of Health and Human Services (HHS)
Health conditions/Disability measures

Strengths and limitations
Strengths Data include all Medicare-certified HHAs and are ideal for doing research on regional variation and services utilization. <br>Data can be linked with other CMS datasets.<br>Rates calculated from OASIS data are risk-adjusted to make comparisons between health agencies possible.<br>Comparisons can be made on national/state/facility level for different time periods.
Limitations Patient-level data not available.<br>Several quality measures have been revised over time and may not be comparable across all time periods.<br>Outcome of care and utilization measures are risk-adjusted, however bias could still be introduced from other unadjusted characteristics of the patients or the agencies, e.g. an agency only accepting patients who have a better prognosis for specific conditions.<br>Data limited to Medicare beneficiaries and Medicare certified agencies only, not necessarily representative of all home health patients and providers.
