Risk adjusted mortality and readmission rates in Veterans hospitalized in VA hospitals
Analysis of risk adjusted mortality in acute myocardial infarction, congestive heart failure, and pneumonia in VA hospitals performed by the VA Inpatient Evaluation Center. |
| Data: |
Inpatient and outpatient administrative International Classification of Disease, Clinical Modification (ICD-9-CM) codes from the VHA Patient Treatment File and the VHA Medical SAS Datasets for outpatients (Visit and Inpatient Encounter Files), housed at the Austin Automation Center. |
| Cohort: |
Patients over the age of 65 years (to allow comparison to publically available Medicare data) admitted to VA hospitals with diagnoses of acute myocardial infarction, congestive heart failure, and pneumonia from October 1, 2006 through September 30, 2009. |
| Methods: |
Adapted from those developed by Krumholz et al (see references below). |
