Implementing automation and information technology in medicine and pharmacy can reduce the number of medical errors. The automated medicine dispensing system Unit Dose, a computerized system of doctor’s orders and a barcode system to identify a single medicine dose with the patient are modern technologies that avert medical errors. Errors in pharmacotherapy are dangerous for the life and health of patients. The system of distributing medicines in which the hospital pharmacy fills orders for medicines for the hospital ward and not for the individual patient is still dominant in Poland. This system is insecure and poses a risk of generating errors in the administration of medications, in the documentation of medical recommendations and evaluation of the process of pharmacotherapy, especially in financial terms. For a several years now, hospitals in Poland have been introducing the Unit Dose medicine distribution system which enables the creation of electronic doctor’s orders and supervision of these orders by a pharmacist in the hospital pharmacy in terms of interaction between drugs and maintaining a proper drug dosage regimen, as is the case in hospitals around the world where such distribution systems have been used for years. A medicine distribution system is an important element necessary to ensure efficient functioning of the hospital. The Unit Dose medicine distribution system increases the safety of pharmacotherapy and reduces the cost of treatment. It also allows clinical pharmacists working in hospital pharmacies to directly influence the applied pharmacotherapy and work in the hospital ward. The Unit Dose medicine distribution system is the future of Polish and world hospital pharmacy.
