Medication related problems (MRPs) remain a serious concern particularly in primary care settings. A recent UK study found that one in 20 prescription items in general practice included an error, affecting 1 in 8 patients. Although the majority of these errors were described as being either mild or moderate in severity, 1 in 550 of all prescription items contained an error determined to be severe (7). In addition, significant medication wastage has been found within general practice settings in England with an estimated £300 million worth of prescribed medications being wasted each year in primary and community care (8). Optimisation of drug therapy and prevention of MRPs can reduce health care expenditure, potentially save lives and enhance patient quality of life (9-13).
