Tables

2.15 Postoperative pulmonary embolus or deep vein thrombosis (DVT) per 1,000 surgical discharges (excluding patients admitted for DVT, obstetrics, neonatal, and plication of vena cava before or after surgery; based on secondary diagnoses of DVT 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.

Denominator

Hospital surgical patients, excluding patients admitted for deep vein thrombosis, obstetrics, neonatal, and plication of vena cava before or after surgery.

Numerator

Comments

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 12 in the AHRQ Patient Safety Indicators software documentation.
