How central support built capacity to deliver a health‐promoting intervention for older adults in Canada

Abstract

Most implementation frameworks note that a central support unit (CSU) is key to successful implementation and scale-up of evidence-based interventions (EBIs). However, few studies investigated core functions of CSUs-such as capacity building-to better understand their essential role in implementing EBIs at scale. Therefore, the aims of our study are to (1) describe the role that a CSU plays to build capacity in delivery partner organisations, to enable implementation and scale-up of a health-promoting intervention (Choose to Move [CTM]) for older adults, and (2) identify elements within capacity-building strategies deemed essential to effectively implement CTM in diverse community contexts. CTM is a flexible, scalable, community-based health-promoting physical activity (PA) and social connectedness intervention for older adults. In 2018-2020, eight health and social service societies, rural or remote municipalities or community-based organisations delivered 22 CTM programmes that served 322 older adults. We conducted in-depth interviews with delivery partners (n=23), and a focus group with the central support system (n=4). CSU provided a sounding board to organisations to create buy-in (adoption) and plan ahead. Essential elements within capacity-building strategies included: a support unit champion, enhanced delivery partner skills, self-efficacy and confidence; interactive assistance to answer questions and clarify materials. There is a key role for capacity-building under the stewardship of the CSU to promote implementation success. Investigating specific elements within capacity-building strategies that drive implementation success continues to be a relevant question for implementation science researchers, that deserves further attention.
