Implementation science has grown significantly over the past two decades, with increased research, training, and funding opportunities across clinical, community, and public health systems. However, rapid growth has created challenges in balancing integration with biomedical research and ensuring studies are relevant to practice and policy. The field aims to build a "big tent" to support the next generation of impactful science, emphasizing collaboration among researchers, practitioners, and policy makers. The NIH has played a key role in advancing implementation science through funding, training programs, and research initiatives. The field has expanded globally, with significant investments in areas such as HIV prevention and non-communicable disease care. Implementation science has also seen growth in training programs, including the TIDIRH and TIDIRC, which have helped build capacity in mental health and cancer research. Despite this growth, challenges remain, including the need for more rigorous and relevant research, better engagement with stakeholders, and the development of robust outcome measures. The field must also address issues such as siloed training, limited capacity building, and the need for more inclusive and comprehensive training programs. The ultimate goal is to create a "big tent" that supports a wide range of implementation science efforts, ensuring that research is relevant, rigorous, and beneficial to society. The field must also focus on improving health equity, ensuring that implementation science is grounded in the needs of patients, practitioners, and policymakers. The future of implementation science depends on continued investment, collaboration, and a commitment to advancing the field in a way that is both rigorous and relevant to real-world applications.Implementation science has grown significantly over the past two decades, with increased research, training, and funding opportunities across clinical, community, and public health systems.
