administration of medicines to groups of patients who may not be individually identified before presentation for treatment’
‘should be reserved for those limited situations where this offers an advantage for patient care (without compromising patient safety) and where it is consistent with appropriate professional relationships and accountability’
Safe Prescribing Practice 1 Building a Safer NHS for Patients – Improving Medication Safety (2004) Recommendations for safer prescribing: All serious prescribing errors and ‘near
misses’ should be reported to the NPSA Prescriptions should always carry patient
directions and never be issued with the instruction ‘as directed’
Particular attention should be paid to checking the accuracy of complex dose calculations
Safe Prescribing Practice 2 The treatment plan, including how the
response to drug therapy is to be monitored, should be clearly documented in the patient’s clinical notes
Prescribers should have access to a pharmacist who is able to provide advice on the drug treatment plan
Where possible aims and side effects of drug treatment should be discussed with the patient or their representative
Safe Prescribing Practice 3 Prescribers should be trained and
assessed as competent before being required to prescribe
Prescribers should follow local and national prescribing standards
Where available, electronic prescribing systems should always be used
Actual and potential prescribing errors should be recorded and reviewed regularly to raise awareness of risk
ADRs – only 10% reported
