Nursing Workforce as a Strategic Pillar of Sustainable Health Systems

Nurses constitute a cornerstone of every modern health system, as they stand at the frontline of care delivery and directly influence the safety, continuity, and quality of healthcare services. Nevertheless, they are often required to work under highly demanding and frequently exhausting conditions, characterized by heavy workloads, limited resources, and minimal opportunities for professional development. These conditions place a significant strain on nurses’ physical and mental resilience and directly affect the quality, continuity, and safety of care, increasing the risk of errors, delays, and unequal coverage of patients’ needs. At the same time, they foster an environment of professional burnout, within which an increasing number of nurses express intentions to leave the profession, with four in ten reporting such considerations. International experience demonstrates, however, that this trajectory can be mitigated to a certain extent. Countries that have chosen to invest strategically in the nursing workforce—by ensuring decent and safe working conditions and by establishing clear pathways for professional advancement through a structured career ladder—have succeeded in upgrading the role of nurses, enhancing the status of the profession, retaining their human resources, and, most importantly, achieving measurable improvements in care outcomes and patient safety. Within these systems, advanced and specialized professional roles are established, such as the Advanced Nurse Practitioner and the Nursing Consultant. Following accredited education and within a clearly defined regulatory framework, these roles are granted increased clinical autonomy in patient assessment, diagnosis, and management. In parallel, they actively participate in decision-making processes related to care organization, lead educational and research initiatives, and act as critical links between clinical practice, healthcare management, and health policy development. The development of similar roles, appropriately adapted to the Greek context, could serve as a powerful lever both for improving the quality and safety of care and for creating meaningful incentives for career progression, retention, and the attraction of new nurses to the public health system.
