3 causes of venous thrombosis also Venous stasis, trauma/endothelial damage,
called, Virchow's Triad hypercoagulability
Venous stasis Slowed blood flow in veins. Caused by immobility,
myocardial infarction, CHF, hypotension, COPD,
obesity, pregnancy, previous DVT, extrinsic
compression, SVC syndrome, paraplegia, surgery
associated conditions.
2 types of Trauma/endothelial Intrinsic and extrinsic
damage
Intrinsic trauma is Damage to the vessel wall from intravenous drugs
or a catheter. Increased use of PICC line results in
higher incidence of upper extremity thrombus,
usually developing at most proximal portion of
PICC line.
Extrinsic trauma is Damage caused by an accident, which can occur at
any site of the body.
, Hypercoagulability is associated with Pregnancy, cancer, oral contraceptives and/or
hormone replacement therapy, inherited states,e.g.,
factor V Leiden or protein C, protein S, or
Antithrombin III deficiency
Sensitivity, and -Ability of a test to detect disease, how many tests
How to calculate? are correctly called positive.
- # of true positives divided by # of all positive
tests by gold standard, or TP/TP+FN
Specificity, and how to calculate? -Ability of a test to identify normality, or how many
results were correctly called negative.
- # of true negative divided by # of all negative
tests by gold standard, or TN/TN+FP
Positive predictive value, and how to -percentage of test results that accurately predict
calculate? abnormality, or what % correctly predicted disease.
- # of true positive test divided by # of all positive
tests, or TP/TP+FP
Negative predictive value, and how - percentage of test results that accurately predict
to calculate? normality, or what % correctly predicted absence
of disease.
- # of true negatives divided by # of all negative
tests, or TN/TN+FN
Accuracy, and how to calculate? - % of correct tests, or how well does the test both
detect and rule out disease.
- total # of correct tests divided by total # of all
tests, or TP+TN/TP+FP+FN+TN
