Data Sources
Our HMO and Regional Hospital Report Cards use data from many sources, and combine them into one format that we hope makes this data more user-friendly. Some data is collected or obtained from external sources, these are described below.
HMO Data
Medical Reports
The HMO medical data we use comes from two sources: HMO data reports and consumer opinion surveys. The performance data contained within the 2010 Report was reported in 2008 and is the most recent data available.
HMOs collect and report data on a set of standard measures. HEDIS is a nationally recognized measurement set that serves as a standard measuring tool to compare HMOs. All the clinical measures used in this report card come from HEDIS, so that an HMO's performance in New York, New Jersey, Connecticut, Rhode Island, or Vermont can be compared to other HMOs, both within the state and nationally.
Consumer Opinion
HMOs in New York, New Jersey, Connecticut, Rhode Island, and Vermont survey their members on satisfaction with the HMO. The questions used in the survey were derived from the CAHPS 4.0H survey, which is part of the HEDIS measurement set. The HMOs contract with independent survey firms to conduct the surveys.
We obtained HEDIS data from the following:
- New York State Department of Health
- State of New Jersey Department of Banking & Insurance
- State of Connecticut Insurance Department
- Vermont Department of Banking, Insurance, Securities & Health Care Administration
- Rhode Island Department of Health
HMO Pricing
HMOs report the monthly premium they would charge a retail customer for a standard plan that includes basic services, and do not reflect discounts available for group purchasing. Rates change often, and you should always call the HMO for an up-to-date price.
We obtained New Jersey HMO pricing data from the State of New Jersey Department of Banking and Insurance, the New York pricing data was obtained from the New York State Insurance Department.
Hospital Data
Medical Reports
The appropriate care data presented in our report card comes from New York, New Jersey, Connecticut, Rhode Island, and Vermont State hospitals that volunteered to submit their data for public reporting. The clinical measures reported here focus on heart attack, heart failure, pneumonia and surgical infection prevention. Each rate calculation reported is based upon the hospital's relevant discharges.
We obtain this data from the U.S. Department of Health and Human Services Centers for Medicare and Medicaid Services. We then report the data provided, and calculate the composite scores.
The data available to us at time of publication included reports up until December of 2008. In this report, a hospital year begins in January and ends in December.
Administrative Data
The information we present on hospital stays is derived from the following:
- New York State's Department of Health Statewide Planning and Research Cooperative System (SPARCS)
- The State of New Jersey Department of Health and Senior Services uniform billing data files (UB-92 inpatient)
- State of Vermont Department of Banking, Insurance, Securities & Health Care Administration - Vermont Uniform Hospital Discharge Data Set (VUHDDS)
- Rhode Island Department of Health Uniform Hospital Discharge Data Set
The data used in our HMO and Regional Hospital Report Cards come from de-identified versions of this data. No patient-specific data is known to us at any time.
We sort this data using a variety of tools, including the Agency for Healthcare Research and Quality's Inpatient Quality Indicators.
Patient Satisfaction
We obtain this data from the U.S. Department of Health and Human Services Centers for Medicare and Medicaid Services.
