The domain of public health management has seen an increase in emerging issues that require attention to improve organizational performance. To address these challenges, this study presents a systematic review of the literature conducted between 2015 and 2023 to illuminate trends in healthcare research, including leadership and negotiation. Based on the PRISMA analysis framework developed by Liberati et al. (2009), we took an approach to assess the coverage of public health management research. Using selection criteria based on the SCOPUS database, our investigation identified 2674 articles. These publications were subjected to analysis, selecting 54 articles deemed particularly insightful and impactful. Furthermore, we developed a conceptual model using Grounded Theory that accentuates the key determinants that influence organisational performance in healthcare institutions. The main factors examined in our model include healthcare negotiation, organizational behaviour, leadership, evidence-based practices, sustainability, and corporate governance. The results of our study shed light on the intricate relationships between these determinants and their impact on overall performance in the public health sector. By elucidating these dynamics, our research provides valuable information to policymakers, administrators, and practitioners striving to achieve excellence in healthcare management. Based on our analysis, we propose an agenda for future research in public health management. This agenda seeks to address knowledge gaps, explore new approaches, and stimulate innovation in addressing healthcare organizations' complex challenges. By focusing on areas such as adaptive leadership strategies, transformative negotiation techniques, evidence-based practice, and sustainable governance models, our proposed agenda aims to catalyse advances in this field, ultimately leading to better health outcomes for individuals and communities. In conclusion, this study represents a significant contribution to public health management. Its review and the development of a conceptual model and research agenda provide stakeholders with the tools and knowledge needed to promote optimal organizational performance and drive positive change in this domain.
