Dartmouth Atlas Measures
General Atlas Rates
- Medicare Reimbursements
- Medicare Mortality Rates
- Selected Primary Care Access and Quality
- Selected Hospital and Physician Capacity
- End-of-Life Chronic Disease
- Hospital and Post-Acute Care
Supplemental Research Data
- Crosswalks
- Geographic Boundary files
- Coding Trends
-
- ICD9 and ICD10 files
- Longitudinal Research FilesThese files are intended to make our database easier to use for researchers conducting longitudinal studies. They include data for multiple years for each measure, most going back at least as far as 2008, allowing researchers to access several years' worth of Dartmouth Atlas rate data.
- Medicare Reimbursements
- Ambulatory Care Quality
- Hospital Discharges (medical and surgical)
- Post-Acute Care
- End-of-Life Inpatient Care (all decedents)
- Care of Chronically Ill Patients (last 2 years of life)
- Mortality (by HMO status)
- Hospital Research Data
- Hospital Tracking Files
These files are datasets that capture hospital mergers, closures, and acquisitions over time. - DRGs by Provider
- Cardiac Care Hospital
- Hospital Cost file (1998-2012)
- Hospital Tracking Files
- Census Data
HEDIS Measures
Healthcare Effectiveness Data and Information Set (HEDIS) includes more than 90 measures across 6 domains of care:
- Effectiveness of Care.
- Access/Availability of Care.
- Experience of Care.
- Utilization and Risk Adjusted Utilization.
- Health Plan Descriptive Information.
- Measures Collected Using Electronic Clinical Data Systems
The DAC uses HEDIS to build some of the Dartmouth Atlas measures. Example code for using HEDIS measures published on Dartmouth Dataverse.
Clinical Classifications Software (CCS) Measures
The Clinical Classifications Software (CCS) for ICD-9-CM is a diagnosis and procedure categorization scheme that can be employed in many types of projects analyzing data on diagnoses and procedures. CCS is based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM), a uniform and standardized coding system. The ICD-9-CM's multitude of codes - over 14,000 diagnosis codes and 3,900 procedure codes - are collapsed into a smaller number of clinically meaningful categories that are sometimes more useful for presenting descriptive statistics than are individual ICD-9-CM codes.
Claim Attending Physician Specialty Code
These codes are used with Home Health Agency (Fee-for-Service), Hospice (Fee-for-Service), Inpatient (Fee-for-Service), Outpatient (Fee-for-Service), Skilled Nursing Facility (Fee-for-Service)

Risk Adjustment
The Chronic Conditions Data Warehouse (CCW) defines 27 common chronic conditions and 39 other chronic or potentially disabling conditions to help researchers identify cohorts of beneficiaries with specific conditions.
