Editorial T he concept of quality associated to health care has evolved considerably since Florence Nightingale, through Ernest Codman and Avedis Donabedian until today, being a focus of increasing interest for health professionals and researchers. Currently, both perspective and purpose in health management are based on a paradigm of providing care with focus on quality. With this paradigm, having clear strategies for a sustainable development of this new culture is fundamental, so that it can add to care high levels of excellence and safety in a coherent and integrated manner. Monitoring quality through an independent observatory is fundamental. Furthermore, quality indicators must be added with a proactive assessment of statistics, prescriptions, claims, legal proceedings, sentinel cases, publications, opinion of users and professionals, etc. Performance of nurses frames a complex process, and I highlight the fundamental values of dignity of the professionals, encouraging their autonomy to maximize well-being throughout their lives. Therefore, displaying competence, accuracy, and professionalism is important to improve the quality of care they provide. These aspects require proactivity in finding appropriate responses, planning and action based on the best available evidence, and continuous improvement with high efficiency and effectiveness. Investment, reflection, and investigation on care quality remain crucial in forming good professionals.
