Use of the All Patient Refined-Diagnosis Related Group (APR-DRG) Risk of Mortality Score as a Severity Adjustor in the Medical ICU

Abstract

Objective: To evaluate the performance of APR-DRG (All Patient Refi ned-Diagnosis Related Group) Risk of Mortality (ROM) score as a mortality risk adjustor in the intensive care unit (ICU).Design: Retrospective analysis of hospital mortality.Setting: Medical ICU in a university hospital located in metropolitan New York.

National treatment practices in the management of infectious intracranial aneurysms and infective endocarditis

“…The APR-DRG system is a joint development of 3M Health Information Systems (Salt Lake City, Utah, USA) and the National Association of Children's Hospitals and Related Institutions 10. The APR-DRG scores are calculated from discharge billing codes and are based on primary and secondary discharge diagnosis, age, and pre-existing medical conditions 11 12. The severity of illness subclasses based on the risk of mortality are minor, moderate, major, and extreme severity of illness.…”

The burden of dialysis-requiring acute kidney injury among hospitalized adults with HIV infection

“…We extracted demographics, concurrent diagnoses, hospital-level characteristics (geographical region, size, and teaching status) and estimated comorbidity burden and mortality risk using the validated All Patient Refined Diagnosis Related Group (APRDRG) mortality score. [13] Specific diagnoses previously associated with increased risk of AKI were identified by ICD-9-CM codes for CKD, diabetes mellitus, hypertension, HCV, liver disease, sepsis, heart failure, cardiac catheterization, and mechanical ventilation. [14–17]…”

Outcomes After Vena Cava Filter Use in Noncancer Patients With Acute Venous Thromboembolism

“…20,21 Proprietary software from 3M (all patient refined-diagnosis-related group grouper, version 24) was applied to every record to generate a severity of illness level and a risk of mortality level at the time of admission. 22,23 Software categorized each of these parameters as mild, moderate, major, or extreme. Hospital characteristics were specified on the basis of size (<100, 101-200, >200 beds), type (private, Kaiser affiliated, academic), location (rural or urban), and kind (profit, not for profit).…”
