Table 2 Utilities used in the decision analysis

From: Prophylactic anticoagulation to prevent venous thromboembolism in traumatic intracranial hemorrhage: a decision analysis

Utility Baseline value Published ranges Threshold value within published range Threshold value reached between 0 and 1
Baseline 0.96 [36] 0.95 to 1.0* No No
LMWH prophylaxis 0.99 [27] 0.9 to 1.0* No No
Living with DVT 0.95 [27] 0.92 to 1.0* No Yes (> 0.9+)
Living with PE 0.7 [35] 0.6 to 0.9 [32] No No
Living with massive systemic bleed 0.7 [27] 0.6 to 0.8* No No
Living with a non-disabling ICH 0.75 [33, 34] 0.6 to 0.8 [33, 34, 56, 57] No No
Living with a disabling ICH 0.39 [33, 34] 0.14 to 0.43 [33, 34, 57] No No
  1. Table of utilities and plausible ranges used for the decision analysis. Ranges with an asterisk (*) were generated from a consensus of authors. The last two columns indicate variables for which a threshold value was identified in one-way sensitivity analysis. Values with a plus (+) indicate a threshold value above which withholding anticoagulant prophylaxis becomes the preferred strategy. DVT: deep vein thrombosis; ICH: intracranial hemorrhage; LMWH: low molecular weight heparin; PE: pulmonary embolism
