Study notes problems in hospital infection rate risk-adjustment models

A recent article in the American Journal of Medical Quality by researchers from 3M, assisted by J. Graham Atkinson, DPhil, Executive Vice President for Research and Policy of the Foundation, raises concerns with Medicare’s current risk-adjustment model used for standardized infection ratios. The authors looked at hospital intensive care units (ICU) and found great variation in reported ICU utilization among admissions for congestive heart failure with alarming data revealing that the designation of ICU versus non-ICU care was unrelated to patient severity.

 

The authors note that policy intended to reduce hospital acquired infections is good and tying financial incentives to improvement appropriately sends a strong message that quality of care is important. However, they question policy that can mislead patients and stakeholders on hospital performance and stress that when wide-spread variation is found in a program with billion-dollar payment adjustments, a formal review of risk-adjustment methods is urgently required.
