Designs and methods for implementation research: Advancing the mission of the CTSA program

Area of Science:

• Implementation Science
• Translational Research
• Healthcare Delivery Systems

Background:

• The Clinical and Translational Science Award (CTSA) program was established by the US National Institutes of Health (NIH) to overcome challenges in translating research into practice.
• Implementation science has emerged as a distinct discipline to address the gap between discovering interventions and their real-world application.
• Implementation research differs from effectiveness research by focusing on systems supporting intervention adoption and fidelity, rather than solely clinical outcomes.

Purpose of the Study:

• To propose how the CTSA program can leverage the growth of implementation science.
• To outline strategies for integrating implementation science methods and designs within CTSA research.
• To encourage collaboration and training to advance implementation science.

Main Methods:

• Implementation research employs designs such as experimental, quasi-experimental, observational, hybrid effectiveness-implementation, simulation modeling, and configurational comparative methods.
• These methods build upon foundational elements of efficacy and effectiveness research.

Main Results:

• Specific research designs and methods are being used to illustrate applications within implementation science.
• The CTSA program is encouraged to integrate state-of-the-science implementation methods into its research.
• Collaboration with other NIH institutes and providing training in implementation science are key recommendations.

Conclusions:

• The maturation of implementation methodologies presents an opportunity for mutual benefit between implementation science and the CTSA program.
• Cross-fertilization of expertise and shared infrastructures can advance healthcare globally.
• Enhanced collaboration can accelerate the translation of EBIs into practice.
