Bnf algorithm
WebRecognizing the power of a simple concept, derived essentially from Bayes theorem, that discordance between the clinical PTP and the test result should raise suspicion of a false negative test (if high PTP) or false positive test (if low PTP), we sought to derive prediction rules for suspected DVT and for suspected PE. WebWarfarin 1 mg or 2 mg daily is generally an acceptable starting dose. The average daily maintenance dose is usually around 5 mg daily; however, there is wide variation, and the daily dose may be between 1–15 mg for some people. Specialist advice should be sought if the person has a prolonged baseline prothrombin time.
