Chapter 5 explores the central importance of integrating public health and primary care to the PHC approach. Public health and primary care add value to each other. Separating them because public health has a population perspective, while primary care typically focuses on the individual, is artificial and creates unnecessary barriers. PHC integrates both perspectives, encouraging greater efficiency and effectiveness, and creating the conditions for more community engagement and multisectoral action, so strengthening health systems and fostering resilience. Key messages include: ■ Primary care and public health services have natural synergies, particularly in the five key areas of: ■ health protection ■ health promotion ■ disease prevention ■ surveillance, monitoring and population health analysis ■ public health emergency preparedness and response. ■ A PHC-oriented system can integrate primary care and public health in a range of ways from maintaining two distinct services but ensuring mutual awareness, through cooperation and collaboration, to full integration in a single, merged organization. ■ Enabling the integration of two strands of health care delivery with different paradigms is not straightforward in practice. Country experiences highlight the importance of: ■ creating a clear shared vision, goals and mandates that public health and primary care co-own ■ acknowledging the distinct training, culture and ways of working in public health and primary care, and ensuring that change management and leadership styles acknowledge these differences ■ revisiting education and training to combine primary care and public health perspectives, and to make collaboration the norm ■ establishing shared data systems and shared protocols that bridge individual patient and community-level data and facilitate integration ■ joint funding that minimizes or rules out any perception of competition for resources.

Chapter 5 emphasizes the crucial role of combining public health and primary care in the Primary Health Care (PHC) approach. Both public health and primary care enhance each other's value. The separation of the two, due to public health's population perspective and primary care's individual focus, is artificial and creates unnecessary obstacles. PHC merges these two perspectives, promoting greater efficiency and effectiveness, fostering more community involvement and multisectoral action, thereby strengthening health systems and promoting resilience.

The key points include:

1. Primary care and public health services naturally synergize, especially in five key areas: health protection, health promotion, disease prevention, surveillance, monitoring and population health analysis, and public health emergency preparedness and response.

2. A PHC-oriented system can integrate primary care and public health in various ways, from maintaining two separate services with mutual awareness, through cooperation and collaboration, to full integration in a single, merged organization.

3. The integration of two strands of health care delivery with different paradigms is not straightforward in practice. Country experiences underline the importance of creating a clear shared vision, goals, and mandates that public health and primary care co-own. It's also important to acknowledge the distinct training, culture, and ways of working in public health and primary care, and ensure that change management and leadership styles recognize these differences.

4. It's necessary to revisit education and training to combine primary care and public health perspectives, and to make collaboration the norm. Establishing shared data systems and shared protocols that bridge individual patient and community-level data and facilitate integration is also crucial.

5. Joint funding that minimizes or rules out any perception of competition for resources is also a key factor.
