Every-one makes mistakes and every one will make the occassional bad mistake • Team work and taking responsibility for checking others and then acting appropriately is the most effective way of reducing patient harm. • All should accept the correction of potential mistakes in good grace • Many safety issues are due to culture and can be corrected by system change • Insulin is the most common cause of administration error • Anticoagulants are the most common cause of life threatening prescribing error. • All clinical staff should know the risks with prescribing so they can be detected.
