Abstract; Background Global concern with strengthening institutions is evident and has been underscored in the wake of the COVID-19 pandemic. Trusted or trustworthy institutions are vital in addressing institutional capacity strengthening, but there is limited research on institutional trust and how to build it. A preliminary approach entitled, Trusted Institutions (TI), identifies six essential elements of trust including: team culture, autonomy, scale and longevity, commitment to quality and ethics, sustainability, and good fit with local context and culture. We aimed to explore capacity building initiatives and the notion of ‘trust’ within non-government health institutions in low- and middle-income countries (LMICs) and validate these essential elements of trust through a systematic review.Methods We searched the published literature in PubMed and EMBASE in March 2020 and employed a three-concept search that included “health-related institutions”; “capacity building”; and “LMICs”. The study team used PRISMA reporting guidelines to conduct title and full-text reviews and conduct data extraction and analysis.Results The search yielded 342 unique articles. Seventy-seven references met initial inclusion criteria and underwent full-text extraction; 31 studies were included in the final analysis. Capacity building activities ranged from individual-level skills to institutional systems and structures. All articles addressed at least one element of trust with over half of articles describing sustainability (n = 18; 58%) and good fit with local context and culture (n = 18; 58%). Only 14 (45%) of articles explicitly mentioned the concept of trust either within an institution (intra-institutional) or between two or more institutions (interinstitutional). Four additional themes emerged as relevant to institutional trust including collaboration, communication, extent of institutional networks, and intersectionality.Conclusions This review validates essential elements of trust in the TI approach and documents the importance of building trust both within and between institutions. The TI approach can be used by public health institutions in LMICs to enhance their abilities to achieve institutional missions and meet global targets.
