Handwritten prescriptions have been associated with certain problems such as the risk of misinterpretation and falsification of handwritten prescriptions and the difficulties of legibility, which prompted the use of electronic prescriptions (e-prescriptions). e-Prescription systems are considered as an instrument to minimize medication errors in pharmacies. Electronically produced prescriptions are transmitted to pharmacists by the physicians over a safe network.
Previous research has shown that health professionals play a vital role in adoption and assessment of HIS . Medication errors are frequent in prescriptions, which are one of the most important outputs in health sector. 20% of medical negligence treatment claims result from medications errors. Prescription errors bring extra costs for individuals and have financial impacts on the government. These errors can occur in various stages such as prescription, transcription, dispensing and drug administration and the effects of these errors have varying levels of severity. In parallel to the developments in technology, e-prescription, which has been developed to prevent errors, involves direct transmission of prescriptions from the working environment of physicians to pharmacies via computers. e-Prescription systems record all format information of a prescription in electronic environment. Health institutions, pharmacy, refunding institution and other individuals/stakeholders can access prescription data to the extent they are authorized to, and thus all operations regarding the supply, refund, register and follow-up of medications can be performed in electronic environment. In other countries such as the United Kingdom, e- prescription can be made in two methods: 1) a mechanism in which prescribers can download a prescription automatically from a central network or a mechanism in which the prescribers can produce an e-prescription. However, the system uses paper in prescription infrastructure. 2) A mechanism in which the prescribers can produce an electronically coded signature and can electronically transmit the prescription to the pharmacy rather than physical transport made by the patient. Although verbal prescriptions or those sent by facsimile are legal in the United States, only electronic or handwritten prescriptions are valid in countries like United Kingdom and Holland. Pharmacists can save time by processing the prescriptions which they do not have to manually enter pharmacy information system.
