Inpatient Quality Indicators Overview
What are Inpatient Quality Indicators?
The Inpatient Quality Indicators (IQIs) are a set of measures that provide a perspective on hospital quality of care using hospital administrative data. These indicators reflect quality of care inside hospitals and include inpatient mortality for certain procedures and medical conditions; utilization of procedures for which there are questions of overuse, underuse, and misuse; and volume of procedures for which there is some evidence that a higher volume of procedures is associated with lower mortality.
How are Inpatient Quality Indicators used?
The IQIs can be used to help hospitals identify potential problem areas that might need further study; provide the opportunity to assess quality of care inside the hospital using administrative data found in the typical discharge record; include mortality indicators for conditions or procedures for which mortality can vary from hospital to hospital; include utilization indicators for procedures for which utilization varies across hospitals or geographic areas; and, include volume indicators for procedures for which outcomes may be related to the volume of those procedures performed.
