Process Measure Formula
Numerator: Patients who received no VTE prophylaxis prior to the day before the date of the first positive VTE/PE diagnostic test.
Denominator: Patients who developed confirmed VTE/PE during hospitalization.
* Rate is typically displayed: Numerator/Denominator*1000
Metric Recommendations
Direct Impact: All admitted patients
Indirect Impact: All admitted patients
Calculations:
\(Lives\ =\ \left(VTE\ or\ PE\ Rate_{baseline}-\ VTE\ or\ PE\ Rate_{measurement}\right)\ x\ Total\ Patient\ Days\ _{baseline}\)
\(Lives\ Saved\ =\ 0.104\ x\ \left(Total\ VTEs\ or\ PEs_{baseline}\ -\ Total\ VTEs\ or\ PEs_{measurement}\right)\)
Notes:
Measure exclusions age < 18, LOS > 120 days, comfort measures only, clinical trials, principal diagnosis of VTE or VTE present on admission, provider reason for not administering mechanical and pharmacologic prophylaxis.

Mortality (will be calculated by the Patient Safety Movement Foundation):
Estimated mortality per VTE is 0.104.
