Introduction The application of Information Technology such as computerized physician order entry, automated dispensing cabinets, bedside bar-coded medication administration, and electronic medication reconciliation are important in avoiding medication errors and enhance quality of care. Electronic medication management includes common hospital process such as prescription of medication, dispensing medication orders, and administration of medications. Electronic medication management can reduce medication errors and can also improve efficiency in the medication management process, such as reducing the time required to locate paper medication charts. rnObjective The objective of this project is to design and implement Drug scheduling system for Amanuel mental specialized hospital rnMethodology The methodology used to develop the system is Object oriented analysis and design methodology. Requirement was collected using tools such as interview, observation and document review. Analysis and design of the proposed system was conducted using tools like the data process model, uses case diagram, and class diagram rnDiscussion and Result prescription of antipsychotic medication for psychiatric inpatients is not performed with consistent dosage and duration. As the Medical Doctor who prescribes drug for patients told me, knowing the right dosage of medication is difficult. Estimating the range of dosage depends on the current status of the patient and patient’s response to the medication. For example patient can take 5mg morning and 10 mg evening at 12 hours interval. Using the new system to schedule drug for long duration and inconsistent dosage is difficult. Because of these, when there is change in medication, dosage and duration the system can help the user to edit and update this information. rnConclusion Administering medication safely is the most crucial part of patient care. Nurse plays a vital role in administering medication. This activity is performed multiple times in a day for an individual patient. It is a complex process therefore accurate documentation of the medication administration is very important.
