Patient-Centered Care (PCC) is defined as an approach that prioritizes the needs, preferences, and values of patients, fostering a collaborative relationship between them and healthcare professionals to enhance the quality of health services. The objective of this study was to analyze PCC as a tool to optimize health services, particularly in primary care settings. A bibliographic review of publications from 2010 to 2024 was conducted, gathering evidence from scientific databases such as SciELO, PubMed, and Elsevier, highlighting the importance of key terms such as "humanization of healthcare" and "patient-centered care." The results demonstrated that PCC promotes more humane, empathetic, and personalized care, improving patient satisfaction, treatment adherence, and clinical outcomes, although it faces challenges such as resistance to change, lack of training, and technological constraints. In conclusion, PCC represents an effective strategy to transform health services, provided that specific tools, such as effective communication and shared decision-making, are implemented, and the identified barriers are overcome through institutional commitment and organizational redesign. It is recommended to explore its application in diverse contexts and levels of care, as well as to evaluate its long-term impact on population health.
