Dataset: Home Health Compare (HHC)
|Dataset Full Name||Home Health Compare|
The Home Health Compare (HHC) database contains home health agency level data. Data are collected from summarized patient assessments and Medicare claims. 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). It includes both process of care and outcome of care measures:
|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.|
|Sponsoring Agency/Entity||Centers for Medicare & Medicaid Services (CMS); Department of Health and Human Services (HHS)||Health Conditions/Disability Measures|
|Disability Measures||NA||Measures/Outcomes of Interest|
|Topics||State and regional variations in home health care quality, use of recommended processes, improvement in outcome measures
Health Services Utilization, Hospitalization rates, Quality of Home Health Care, Patient Satisfaction and Experience with Care, Patient-Provider Communication
Process Measures: Timely initiation of care, Influenza immunization received for current flu season, Pneumococcal polysaccharide vaccine ever received, Diabetic foot care and patient education implemented, Depression assessment conducted, Drug education on all medications provided to patient/caregiver, Multifactor fall risk assessment conducted for all patients who can ambulate.
Outcome Measures: Improvement in ambulation, Improvement in bed transfer, Improvement in pain interfering with activity, Improvement in bathing, Improvement in management of oral medications, Improvement in dyspnea, Improvement in status of surgical wounds, Improvement in breathing, Improvement in pressure ulcers, Acute care hospitalizations, Emergency department use without hospitalization, Emergency department use without hospital readmission during the first 30 days of home health
All Medicare-certified home health care agencies nationally.
|Sample Size/Notes||11,181 (January 2020) All Medicare certified home health agencies
Number of agencies varies by year
Aggregated rates from the HHCAHPS patient survey are calculated from a randomly selected sample of patients for each agency.
|Unit of Observation||Service Provider|
|Geographic Specificity||Individual Home Health Care agencies||Data Collection|
|Data Collection Mode||Administrative claims data
Mail, phone or mixed mode interview
Assessment based on review of patient records and observation (subset of OASIS)
|Data Collection Frequency||Quarterly||Strengths and Limitations|
|Strengths||Data include all Medicare-certified HHAs and are ideal for doing research on regional variation and services utilization.
Data can be linked with other CMS datasets.
Rates calculated from OASIS data are risk-adjusted to make comparisons between health agencies possible.
Comparisons can be made on national/state/facility level for different time periods.
|Limitations||Patient-level data not available.
Several quality measures have been revised over time and may not be comparable across all time periods.
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.
Data limited to Medicare beneficiaries and Medicare certified agencies only, not necessarily representative of all home health patients and providers.
