Risk Adjustment for Measuring Healthcare Outcomes
Mobility impairments and use of screening and preventive services.
TLDR
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
