AimsResearch capacity strengthening (RCS) is crucial in enhancing healthcare outcomes, particularly in low‐ and middle‐income countries (LMICs), which face challenges due to limited resources, unequal access to care and the need for evidence‐based decision‐making. We seek to move beyond a surface‐level understanding of RCS, unearthing the core attributes, the factors that precede its implementation and the transformative outcomes it generates within the LMIC healthcare landscape.DesignThis study employs the Walker and Avant approach to concept analysis to comprehensively explore the dimensions and attributes of RCS as it pertains to allied and public health professionals in LMICs, propose empirical referents and suggest an operational definition.Data SourcesOvid MEDLINE, Embase, CINAHL and Cochrane CENTRAL were searched from inception to 27 July 2023, to identify studies on RCS in LMICs. The Walker and Avant approach to concept analysis was selected because it provides a framework for systematically examining and clarifying the meaning and implications of RCS. This method involves a structured process of defining RCS, identifying its attributes, antecedents, consequences and cases, and ultimately providing a clear understanding of its meaning and implications. Identifying empirical referents offers measurable indicators that researchers and policymakers can use to assess the effectiveness of RCS initiatives in LMICs.ConclusionRCS for health professionals in LMICs involves a sustainable process that equips them with essential research skills, fostering the ability to conduct high‐quality research and improve healthcare delivery in resource‐constrained settings.ImplicationsRCS aims to empower health professionals to apply evidence‐based practices, reduce disparities and enhance the well‐being of populations in LMICs.ImpactUltimately, a concept analysis of RCS empowers us to harness the full potential of research to enhance healthcare delivery, improve patient outcomes and advance the well‐being of populations worldwide.
