It is essential for health-care professionals to calculate drug doses accurately (Oldridge et al., 2004). An adverse drug event (ADE/an injury related to the use of a drug) is documented to occur during 0.7-6.5% of hospital admissions in the US, 1.5% in the UK, and 1.8% in Australia (Leape et al., 1991; Bates et al., 1995; Neale et al., 2001; Wilson et al., 1995). The substantial morbidity and mortality associated with ADE`s is well known. In-hospital ADE`s (occurring after or causing admission) are associated with longer hospital stays, increased costs of hospitalization and greater risk of death. In a study, the estimated ADE rate during hospitalization was 4.2 events per 100 admissions, with a cost of US$2162 per ADE. In addition, 3.2% of admissions were caused by ADE`s, with an associated cost of US$6685 per event. 15% of hospital ADE`s and 76% of ADE`s causing admission were judged preventable. The annual cost to the organization for events occurring during hospitalization was US$1.7 million, and the cost of preventable ADE`s was US$260,000, while the projected costs of preventable ADE`s causing admission were $3.8 million. 71% of the serious medication errors occurred at the prescribing stage of the medication-use process (Senst et al., 2001). In another study, ADE`s complicated 2.43 per 100 admissions to the hospital during the study period.
