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.

f3-hcfr-84-supp-091: Acute physiology score (APS) distribution

Mentions: Figure 3 illustrates the distribution of these patients across the range of severity of illness at ICU admission as measured by the APS of APACHE II at ICU admission. Figure 4 reports the mean TISS points during the ICU stay for the same severity of illness ranges. Average cost increases strongly up to the 20 to 24 APS point group, after which average cost declines moderately. The mild reduction in costs above 24 APS points occurs partly because of increased death rates at the higher severity levels and partly because of increased impact of the truncation of costs for outliers.
