Table 1_Mapping the landscape of implementation science training: gaps and opportunities to strengthen capacity for implementation research and practice.docx

Nearly half (47.4%) enrolled ≤10 participants per cohort, and approximately 10% enrolled more than 50 participants. Nearly all programs admitted academic audiences (94.7%), with fewer targeting participants from public health (57.9%) or healthcare providers (43.9%). TCI participants (N = 1,632 for demographic data; N = 436 for qualitative analysis) were a diverse audience representing multiple sectors, most frequently healthcare (26.9%), IS (17.6%), public health (17.0%), and education (15.6%).

Organizational affiliations included nonprofit organizations (22.7%), healthcare institutions (18.1%), higher education (17.7%), and government (15.9%). Through qualitative analysis of TCI participant introductions, we identified four major themes reflecting participants' professional contexts and motivations for IS training: (1) system roles, (2) current implementation activities, (3) learning motivations, and (4) application of IS concepts to their work.</p>Discussion<p>Current IS trainings in North America are primarily focused on a research audience.

Expanding IS implementation training and education to a broader audience, in particular implementation support practitioners who are not engaged in research, but who seek to apply IS to solve problems, is warranted.</p>
