Impact of the implementation of information systems on the practice of nursing professionals in primary health care

Abstract

Introduction: The digitalization of the Brazilian Unified Health System (SUS) aims to improve the quality of care, expand access, and enhance information management. In Primary Health Care (PHC), this process has significantly transformed professional practice, particularly in nursing. However, it still faces challenges such as inadequate infrastructure, low system usability, and negative impacts on workers' health. Objectives: To critically analyze the effects of digitalization in PHC, with a focus on its repercussions for nursing practice. Methods: This study is an integrative literature review. The search was conducted between April and June 2025 in the BVS, LILACS, SciELO, and PubMed databases, using the following descriptors: “Primary Health Care,” “Nursing,” “Health Information Technology,” and “Information Systems.” Articles published between 2015 and 2025, with full-text availability and aligned with the proposed topic, were included. A total of 18 articles were selected to compose the corpus of this study. Results: The studies reveal that digitalization, when implemented without dialogue with professionals or adequate working conditions, intensifies the bureaucratic nature of nursing activities, reduces professional autonomy, and weakens the relational dimension of care. On the other hand, experiences grounded in participation and active listening demonstrate the potential of technology to enhance care quality and strengthen the SUS. Conclusion: Digitalization in PHC will only effectively contribute to the quality of care if it is aligned with real working conditions, values the nursing profession, and upholds the core principles of the SUS.
