e. were treated as out-patients. A cost comparison per ten injections across the range of treatment regimes found tinzaparin to be the most expensive drug (£84.80 per 10 pre-filled syringes) compared to enoxaparin (£64.90 equivalent) and dalteparin (£56.50 equivalent). NICE state that there is no difference in efficacy between LMWH and thus no preference for 1st line choice. Initial evidence suggests dalteparin or enoxaparin are better cost saving alternatives than tinzaparin as 1st choice LMWH. Most regions in the UK have chosen to use dalteparin CAL 101 or enoxaparin as 1st choice as part of a strategy to save money without

affecting patient care. The drug cost however is not the complete picture, since secondary care procurement takes place a much lower cost than primary and is built into the service level agreements with the Trusts. The high compliance with local guidelines (97%) is further underpinned by the 3% who

did not meet the guidelines. All involved patients having a longer duration of treatment than recommended, or being transferred to GP care beyond Navitoclax cost the protocols. Such a low level of non-compliance suggests that there were probably legitimate reasons for the actions which were for the 9 patients. 1. Institute for Safe Medication Practices.

A total of 60 errors were identified at admission in the control group; 24 (80.0%) patients experienced at least one medication error upon admission. At least 85% of errors at discharge were associated with admission errors. Racecadotril 25 (43.1%) of the errors identified at discharge translated into primary care at three months post discharge, however theses can only be confirmed as errors after discussion with the GP. Whilst it is frequently assumed that MR errors in discharge letters translate into primary care,1,2 there is little evidence to support this assertion. The aim of this analysis is to determine whether errors at admission and discharge could be identified from primary care records at three months post discharge and if so, estimate the proportion of errors at discharge which eventually persist in primary care. A pilot MR randomised controlled trial (RCT) was conducted with patients receiving either MR by a pharmacist or usual care.
