Acute physiology and chronic health evaluation (APACHE II) and Medicare reimbursement.

Wagner DP, Draper EA - Health Care Financ Rev (1984)

Bottom Line: The APS is defined by a relative value scale applied to 12 objective physiologic variables routinely measured on most hospitalized patients shortly after hospital admission.For intensive care patients, APS at admission is strongly related to subsequent resource costs of intensive care for 5,790 consecutive admissions to 13 large hospitals, across and within diagnoses.The APS could also be used to evaluate quality of care, medical technology, and the response to changing financial incentives.

ABSTRACT
This article describes the potential for the acute physiology score (APS) of acute physiology and chronic health evaluation (APACHE) II, to be used as a severity adjustment to diagnosis-related groups (DRG's) or other diagnostic classifications. The APS is defined by a relative value scale applied to 12 objective physiologic variables routinely measured on most hospitalized patients shortly after hospital admission. For intensive care patients, APS at admission is strongly related to subsequent resource costs of intensive care for 5,790 consecutive admissions to 13 large hospitals, across and within diagnoses. The APS could also be used to evaluate quality of care, medical technology, and the response to changing financial incentives.

f1-hcfr-84-supp-091: The acute physiology and chronic health evaluation (APACHE) II severity of disease classification system

Mentions: The result of the simplification effort is APACHE II, which is based on 12 of the most commonly measured physiologic measures included in the original APACHE system (Knaus et al., submitted for publication, 1984a). The 12 variables were selected based on clinical judgement as to validity and specificity of the measure, breadth of vital organ system coverage, and objectivity, reliability and frequency of measurement. The 12 variables include vital signs (heart rate, mean blood pressure, respiratory rate, temperature, and Glasgow Coma Score), variables derived from routine venous blood tests (hematocrit and white blood cell count, serum potassium, serum sodium, and serum creatinine), and 2 variables derived from arterial blood gas tests (serum pH and Pa02). Full details are reported in Figure 1.
