Injection practices are a legal obligation of healthcare professionals, but they are also ethically responsible, and the safe maintenance of these practices is extremely important for both patient and employee safety. Due to reasons such as the lack of knowledge and skills of healthcare professionals regarding safe injection, lack of experience, in-service training and periodic training for newly recruited personnel, situations that threaten patient and employee safety occur. Mistakes made in situations requiring technical skills related to injection practices lead to local complications such as ecchymosis, hematoma, pain, abscess, lipodystrophy, infection, and can result in life-threatening situations. In addition, lack of technical skills causes sharp-edge injuries in the world and in excess of their number, and causes blood-borne diseases for many healthcare professionals. In order to prevent these complications and injuries, the education of healthcare professionals requires an education system based on theory and clinical practice, supporting students' cognitive, sensory and psychomotor skills. In the education process, the aim should be to provide clinical skills as well as theoretical knowledge and to develop the acquired skills. Because clinical education allows students to integrate theoretical knowledge with practice in healthcare settings and learn by experience. Gaining competence in parenteral interventions in the clinic is a gradual process and is one of the most important issues in both undergraduate education and postgraduate in-service training. Although clinical practice training is one of the basic practices for learning and acquiring clinical skills in traditional medical and nursing education curricula, it is seen that it is insufficient and it is recommended to benefit from developments in the field of educational technologies in order for practice training to increase patient and student safety. Considering the increasing emphasis on the right of patients to receive care from well-educated health professionals and the right of employees to be safe in risky practices, it is thought that developing a tool that will provide students with the opportunity to practice repeatedly in parenteral injection practice training will be an effective tool in solving all the problems mentioned above. For this purpose, the parenteral practice (intravenous, intramuscular, subcutaneous) skill training module, which is targeted to be developed in the project, aims to improve students' injection skills, provide safe injection practices and ensure their own safety.
