Evaluation of the effect of Z-track technique training on emergency nurses: A single-group pretest–posttest study

This study demonstrated that training improved the nurses' knowledge and skills related to the Z-track technique, leading to increased usage frequency 1 month later. Retention of knowledge and skills was supported by applying the technique in clinical practice. Since theoretical and practical training is often forgotten without regular application, implementing evidence-based standard procedures and in-service training programmes is essential to keep nurses' competencies up to date. These programmes should focus on critical steps for safe injection practices, include hands-on training, and utilize positive reinforcements to enhance professional competence and ensure patient safety.
