\(Lives\ =\left(VTE\ or\ PE\ Mortality_{baseline}-VTE\ or\ PE\ Mortality_{measurement}\right)x\ Total\ Patient\ Days_{baseline}\)
Notes: Hospital acquired VTEs are identified through ICD diagnosis codes. The ICD9 diagnosis codes are: 4534, 45341, 45342, 41511, 41513, and 41519. The ICD10 diagnosis codes are: I824Z3, I82449, I82491, I82423, I2602, I824Y1, I82421, I2692, I82441, I824Y2, I82412, I82429, I82432, I82499, I82422, I82439, I82493, I824Y9, I82419, I2609, I2699, I824Z2, I824Z9, I824Y3, I824Z1, I82413, I82442, I82443, I82492, I82411, I82431, I82433. Qualifying diagnoses that are present on admission are excluded from the numerator.
Total patient days come from daily census counts for each inpatient nursing unit. Census counts are electronically derived at the same time of day each day. These counts may be collected manually if an electronic source is not available.

Data Collection:  

Data collected from final diagnosis codes for encounter as determined by a professional health information coder.

Mortality (will be calculated by the Patient Safety Movement Foundation): 

Estimated mortality per VTE is 0.104.
