Examination of hospital characteristics and patient quality outcomes using four inpatient quality indicators and 30-day all-cause mortality.
The study objective was to examine hospital mortality outcomes and structure using 2008 patient-level discharges from general community hospitals. Discharges from Florida administrative files were merged to the state mortality registry. A cross-sectional analysis of inpatient mortality was conducted using Inpatient Quality Indicators (IQIs) for acute myocardial infarction (AMI), congestive heart failure (CHF), stroke, pneumonia, and all-payer 30-day postdischarge mortality. Structural characteristics included bed size, volume, ownership, teaching status, and system affiliation. Outcomes were risk adjusted using 3M APR-DRG. Volume was inversely correlated with AMI, CHF, stroke, and 30-day mortality. Similarities and differences in the direction and magnitude of the relationship of structural characteristics to 30-day postdischarge and IQI mortality measures were observed. Hospital volume was inversely correlated with inpatient mortality outcomes. Other hospital characteristics were associated with some mortality outcomes. Further study is needed to understand the relationship between 30-day postdischarge mortality and hospital quality.
