 This is a register study. Referrals to hospital in 2014 pre-training and 2017 post-training are examined and the difference is assumed to be because of training and new pathway. Based on population the expected number of referrals due to a suspected DVT should be approximately 100 annually and the expected number after intervention is 30. According to power analysis a reduction from 100 to 76 is statistically significant p0.05.
