Prolonged hospital stays, dissatisfaction of patients with care provided, development of medical conditions, and cases of readmission are some of the negative consequences of medical errors. Therefore, training of nurses to reduce cases of medical errors can be used to improve patient outcomes through competence and efficiency in their operation. Competent nurses perform correct diagnosis, proper care, and giving of the fitting prescription reduce medical errors and improve patient outcomes. PICOT Question In patients admitted to Intensive Care Units (ICU)/ Critical Care Units (CCU), what impact would nurse training have on reducing medication errors and ultimately, minimizing cases of readmission within a few days post-surgery? Research Backgrounds Four articles on the role of nurse training in reducing medical errors are examined. Gorgich et al. (2016) note that medication mistakes are a genuine worldwide problem affecting medical care, compromising patient wellbeing, and can lead to death. The study is critical to nurses since it improves their comprehension of possible medical mistakes and proper systems to stop them. The motivation and goal of the study were to research different elements that lead to the occurrence of treatment mistakes and strategies which can be executed to minimize the errors based on the nurses’ point of view. The research question that guided the study is: What viewpoints lead to medical errors and which procedures can help minimize them based on the nurses’ and nursing students’ point of view? Experience of registered nurses and application of technologies assist in reduction of errors. Pirinen et al. (2015) examine the experiences of registered nurses (RNs) in the process of medication administration. The study notes that nurses are involved in all levels of the medication administration process (MAP). Therefore, the competence of nurses can eliminate or reduce medical errors at any stage. The significance of the article to the nursing profession is in providing evidence that the improvement of nursing care determines the quality of care and patient outcomes. The study’s motivations and objectives were to depict how registered nurses work in different stages in the MAP. Pirinen et al. (2015) additionally intend to apply innovative technologies to build up a medication management process that reduces medication errors. The research question that guided the study is: What is the registered nurses’ view of the prescription organization measure? In addition, examination of medical errors in different settings allow for better understanding of the problem. Bull et al. (2017) investigate mistakes in medication administration in developing nations. The research adds new information to the advancement of drug administration workshops. The study’s purpose is to the improvement of drug calculation capability of nurses in developing economies. The objectives that Bull et al. (2017) sought to achieve include investigating worldwide health partnerships’ commitments to the making of medication drug-dosage. The other goal was to understand learning opportunities and define health psychologists’ role in supporting nurse educators’ work to implement behavioral research into training. The research question relates to worl
