This article examines severity measures used in states and regions to produce comparisons of risk-adjusted hospital death rates and concludes that Severity does not explain differences in death rates across hospitals. Expand
Risk Adjustment for Measuring Healthcare Outcomes
Mobility impairments and use of screening and preventive services.
People with mobility problems were as likely as others to receive pneumonia and influenza immunizations but were less likely to receive other services, and more attention should be paid to screening and preventive services for people with mobility difficulties. Expand
Communicating about Health Care: Observations from Persons Who Are Deaf or Hard of Hearing
