**Background:** Front-line health practitioners lack confidence in knowledge translation (KT), yet are often required to bridge the knowledge-practice gap. Most KT capacity building initiatives focus on researchers rather than the healthcare workforce. This paper reports the development and evaluation of AH-TRIP, a multimodal KT capacity building program for allied health practitioners across geographically dispersed locations in Queensland, Australia.
**Methods:** AH-TRIP was developed over five years (2014–2019) using a pragmatic approach incorporating theory, evidence, stakeholder engagement, and local needs assessment. The program includes five components: (1) training and education (online repository of >30 webinars, 12 case examples, 15 implementation science papers, 16 web links); (2) support and networks (statewide telementoring series with expert panel, local champions); (3) showcase and recognition (annual statewide event); (4) TRIP projects and implementation; (5) evaluation. The RE-AIM framework guided evaluation. Data were collected from 2019–2021 on reach (number, discipline, geographical location), adoption by health services, and participant satisfaction. Inputs cost $AU197,595 per year ($AU143,000 for two funded positions totaling 44 h/week, $AU475 in software licenses, $AU54,120 in-kind contributions).
**Key Results:** A total of 986 allied health practitioners participated in at least one component. The online training platform averaged 944 unique page views per month (range 480–1,422; total 32,112 views from March 2019 to December 2021). The champion network comprised >100 champions annually (2019: n=103; 2020: n=112; 2021: n=105), representing all major allied health disciplines, with a third (n=36) located in regional areas. The telementoring program supported 19 KT projects across four cohorts (2019: n=4; 2020: n=5; 2021: n=10 across two cohorts), involving 25 allied health practitioners and one nurse across seven disciplines. Seven (37%) projects were led by practitioners from regional health services. All telementees (100%, n=26) reported the support was relevant and would recommend it to colleagues. Local funding enabled individual project support for an additional 99 projects. The annual showcase received 49 project submissions (2019: n=17; 2020: n=19; 2021: n=13), with 733 registrations (186 [25%] from regional areas, 89 [12%] from outside Queensland Health). Of 146 survey respondents, 95% (n=138) agreed the event was valuable, 95% (n=138) identified at least one key learning, 96% (n=140) would think about how they used research in practice, and 86% (n=126) had increased understanding and confidence about KT. Nine of 16 public hospital and health service districts plus one public/private partnership adopted AH-TRIP. All seven non- or partial-adopting districts were located in regional areas.
**Clinical Implications:** AH-TRIP demonstrates that a low-cost ($200 per participant or $19,760 per year per adopting health service district), multimodal KT capacity building program can be delivered at scale to support allied health practitioners across geographically dispersed locations. The program fills an identified gap by focusing on novice implementers embedded in health services rather than researchers. High engagement and satisfaction suggest the model is acceptable and feasible. However, the lack of adoption in seven regional districts indicates that targeted strategies are needed to improve equity of access. Future evaluation should focus on impact on individual participants, teams, organizations, and health service outcomes, as well as capturing the cost of avoiding poorly executed projects.
