Measure Set: Surgical Care Improvement Project (SCIP)
Set Measure ID: SCIP-venous-thromboembolism-2
Performance Measure Name: Surgery Patients Who Received Appropriate Venous Thromboembolism Prophylaxis Within 24 Hours Prior to Surgery to 24 Hours After Surgery
Description: Surgery patients who received appropriate venous thromboembolism (VTE) prophylaxis within 24 hours prior to Surgical Incision Time to 24 hours after Surgery End Time.
Rationale: There are over 30 million surgeries performed in the United States each year. Despite the evidence that VTE is one of the most common postoperative complications and prophylaxis is the most effective strategy to reduce morbidity and mortality, it is often underused. The frequency of venous thromboembolism (VTE), that includes deep vein thrombosis and pulmonary embolism, is related to the type and duration of surgery, patient risk factors, duration and extent of postoperative immobilization, and use or nonuse of prophylaxis. According to Heit et al, 2000, surgery was associated with over a twenty-fold increase in the odds of being diagnosed with VTE. Studies have shown that appropriately used thromboprophylaxis has a positive risk/benefit ratio and is cost effective. Prophylaxis recommendations for this measure are based on selected surgical procedures from the 2004 American College of Chest Physicians guidelines.
Timing of prophylaxis is based on the type of procedure, prophylaxis selection, and clinical judgment regarding the impact of patient risk factors. The optimal start of pharmacologic prophylaxis in surgical patients varies and must be balanced with the efficacy-versus-bleeding potential. Due to the inherent variability related to the initiation of prophylaxis for surgical procedures, 24 hours prior to surgery to 24 hours post surgery was recommended by consensus of the SCIP Technical Expert Panel in order to establish a timeframe that would encompass most procedures.
Type of Measure: Process

Included Populations: Not applicable
Excluded Populations: None
Data Elements:
Denominator Statement: All selected surgery patients
Included Populations:
- ICD-9-CM Principal Procedure Code of selected surgeries (as defined in Appendix A, Table 5.10 for ICD-9-CM codes)
AND
- ICD-9-CM Principal Procedure Code of selected surgeries (as defined in Appendix A, Table 5.17-5.24 for ICD-9-CM codes)
Excluded Populations:
- Patients less than 18 years of age

- Burn patients (as defined in Appendix A, Table 5.14 for ICD-9-CM codes)
- Patients with procedures performed entirely by laparoscope
- Patients enrolled in clinical trials
- Patients who are on warfarin prior to admission
- Patients whose ICD-9-CM principal procedure occurred prior to the date of admission
- Patients whose total surgery time is less than or equal to 60 minutes
- Patients who stayed less than or equal to 3 calendar days postoperatively
- Patients with contraindications to both mechanical and pharmacological prophylaxis
- Patients who did not receive VTE Prophylaxis (as defined in the Data Dictionary)

Data Elements:
Risk Adjustment: No.
Data Collection Approach: Retrospective data sources for required data elements include administrative data and medical records. Retrospective data sources for required data elements include administrative data and medical records.
Data Accuracy: Variation may exist in the assignment of ICD-9-CM codes; therefore, coding practices may require evaluation to ensure consistency.
Measure Analysis Suggestions: Measure rates for SCIP-VTE-2 should be analyzed in conjunction with SCIP-VTE-1 in order to identify focus areas for quality improvement. Low measure rates may indicate the need for staff education or evaluation of organizational factors and processes of care. Note that rates for SCIP-VTE- 2 may be lower than those for SCIP-VTE-1 as a result of more stringent criteria. SCIP-VTE-2 requires documentation that prophylaxis was ordered and actually started, whereas SCIP-VTE-1 requires only documentation of an order.
Sampling: Yes. For additional information see Sampling Section.
Data Reported As: Aggregate rate generated from count data reported as a proportion.
