Measure Source

Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators.


2.12 Postoperative hemorrhage or hematoma with surgical drainage or evacuation, not verifiable as following surgery, per 1,000 surgical discharges (excluding obstetrical and neonatal admissions; based on secondary diagnoses only), by patient and hospital characteristics, United States, 2000.

Data Source

Agency for Healthcare Research and Quality, Center for Delivery, Organization, and Markets, Healthcare Cost and Utilization Project (HCUP), Nationwide Inpatient Sample.


Inpatient hospital surgical discharges, excluding obstetrical and neonatal admissions.


Subset of denominator meeting the following criteria:

Secondary diagnosis indicating postoperative hemorrhage or postoperative hematoma.

Secondary procedure indicating postoperative control of hemorrhage or drainage of hematoma.


Procedure code for postoperative control of hemorrhage or hematoma not verified as following surgery.

Rates are adjusted by age, gender, age-gender interactions, comorbidities, and DRG clusters. DRGs are Diagnosis Related Groups which identify patients with similar illnesses.

Although not all states participate in the HCUP database, it is weighted to give national estimates using weights based on all U.S. community, non-rehabilitation hospitals in the American Hospital Association Annual Survey of Hospitals.

This table was created using a beta-test version of the AHRQ Patient Safety Indicators software dated July 2002 that differs from the AHRQ Patient Safety Indicators software currently available on the AHRQ Web site. This measure is referred to as indicator 9 in the AHRQ Patient Safety Indicators software documentation.
