How Data Are Collected

Each quality initiative collects data differently.

1. Nursing home compare uses minimum data set version 2.0 (MDS2.0) data for the quality measures come from the MDS Repository. The MDS is collected on regular intervals for every resident in a Medicare or Medicaid certified nursing home. Information is collected on the resident's health, physical functioning, mental status, and general well-being. These data are used by the nursing home to assess the needs and develop a plan of care unique to each resident.

Regulations require that a MDS assessment be performed at admission, quarterly, annually, and whenever the resident experiences a significant change in status. For residents in a Medicare Part A stay, the MDS is also used to determine the Medicare reimbursement rate. These assessments are performed on the 5th, 14th, 30th, 60th and 90th day of admission.

2. Home Health Compare uses the Outcome and Assessment Information Set (OASIS), which is a group of data elements that represent core items of a comprehensive assessment for an adult home care patient; these core items and a comprehensive assessment serve as the basis for the development of the care plan and ongoing management of the patient; and form the basis for measuring patient outcomes for purposes of outcome-based quality improvement (OBQI). The OASIS is a key component of Medicare's partnership with the home care industry to foster and monitor improved home health care outcomes.

The OASIS assessment data are used to calculate the Home Health Quality Measures and are used to determine the service area for each home health agency that is used in the Home Health Compare search function.

3. Hospital Compare shows measures that are based on data from hospitals' patient records. The data is converted to rates that measure how well the hospitals care for their patients. The Hospital Quality Alliance (HQA) expects to increase the number of measures and the types of conditions and treatments on which the hospitals will report over time. As you look at the data, it is important to know that small differences in the percentages usually don't show that one hospital is significantly better or worse. It is better to look at larger differences. Percentages may be affected by such factors as how many patients are included in the calculation of the rate. This doesn't necessarily reflect the quality of the care you will receive.

Psychiatric, children's, rehabilitation and long-term care hospitals currently are not reported on this website, although many have agreed in principle to provide data using standard quality measures. This is due to the fact that the conditions currently measured -- care of adults with a heart attack, heart failure, or pneumonia -- are less commonly treated in these settings

4. Dialysis Facility Compare (DFC) allows patients and their family members as well as professionals to compare the quality of dialysis facilities across the country, and to access a variety of kidney and dialysis resources. DFC shows measures that are based on CMS Administrative Data. The information or data on Dialysis Facility Compare comes from two sources: Standard Information Management Systems (SIMS) and Renal Management Information System (REMIS). The ESRD Networks verify, update, and send data in SIMS to Medicare monthly.  REMIS is a database maintained by Medicare with data about dialysis facilities. It includes: Demographic, medical claims, payment and entitlement data on people with Medicare who have ESRD; Certification and other information for Medicare-approved ESRD providers; and Aggregate ESRD patient information.
