Ensure a completed transfer form is received from the initiating prescriber to fulfill the NPSA Guidance listed below:
When transferring prescribing from Secondary to Primary Care it is essential that the following information, in line with NPSA guidance, is made available to healthcare professionals involved in prescribing, dispensing and administration:
1. A patient’s weight is used as the basis for calculating the required treatment dose of LMWH. The weight must be accurately recorded in kilograms (kg) in the inpatient medication chart (when in use) and clinical record. Patients should be weighed at the start of therapy and, where applicable, during treatment.
2. Renal function is considered when prescribing treatment doses of LMWHs. The renal function test should not delay initiation of the first dose but every effort must be made to base subsequent dosing on these results.
3. Dose calculation tools are available for a range of body weights, specific clinical indications and LMWH products, and that consideration is given to rationalising the range of LMWH products used in the organisation.
4. Essential information such as dose, weight, renal function, indication and duration of treatment is communicated at transfers of care (e.g. by discharge letters) and used to ensure that future doses are safe.
5. Dosing checks based on patient information are made by healthcare professionals who review, dispense or administer LMWHs when this information is readily available to them.

Reducing treatment dose errors with low molecular weight heparins July 2010
In terms of pharmacological prophylaxis for VTE, NICE recommend the following:
* Offer pharmacological VTE prophylaxis to general medical patients assessed to be at increased risk of VTE. Choose any one of fondaparinux sodium, low molecular weight heparin (enoxaparin, tinzaparin, daltaparin) or unfractionated heparin (for patients with renal failure)
* Start pharmacological VTE prophylaxis as soon as possible after risk assessment has been completed.
* Continue until the patient is no longer at increased risk of VTE.
