Prevention Quality Indicators Overview
What are Prevention Quality Indicators?
The Prevention Quality Indicators (PQIs) identify issues of access to outpatient care, including appropriate follow-up care after hospital discharge. More specifically, the PQIs use data from hospital discharges to identify admissions that might have been avoided through access to high-quality outpatient care. The PQIs are population based and adjusted for covariates.
The PQIs are area-level indicators that enable tracking of potentially preventable hospitalizations, including diabetes, in a community or region. The PQIs are a key tool for community health needs assessments.
How are Prevention Quality Indicators used?
The PQIs provide a good starting point for assessing quality of health services in the community. The PQIs use administrative data found in a typical hospital discharge abstract to:
- Flag potential health care quality problem areas that need further investigation;
- Provide a quick check on primary care access or outpatient services in a community;
- Help organizations identify unmet needs in their communities.
