As health professionals, nurses actively and directly participate in achieving the best possible welfare for the patient and have a direct influence on the patient’s health outcome. By applying professional standards, nurses can take responsibility for professional conduct, the quality of care they provide, and their own practice. This work is focused on the principle of improving care and improving the overall quality of treatment, which contributes to safe treatment aimed at achieving favorable health outcomes, thereby reducing treatment costs for the individual, family, employer, and society. To look at the improvement and development of the quality of health care (patient safety) requires knowledge, selection, and application of specific methods and tools adapted to the capabilities of individual health institutions. Current nursing practice is burdened with problems that can affect the quality of care provided, the safety of patients, and the safety of nurses in the workplace. The establishment of clearly defined standards is necessary, given that they represent the framework for the implementation of all nursing activities. Standards are the basis of nursing action that ensures legal, professional, and scientifically based action. They serve as a measure of the quality of practice and the development of the nursing profession. Employers have a responsibility to ensure a support system, including human and material resources, that will enable standards to be met. Quality control provides nurses and other healthcare systems, education, nurses, and physical therapists workers with feedback on the quality of their work as well as on how it can be improved. Users should also be actively involved in determining the quality of organizational care.
