Leadership Dynamics and Organisational Culture in Resource-Constrained Healthcare: A Mixed-Methods Analysis of Frontline Management Effectiveness

Abstract Effective leadership represents a critical adaptive mechanism in low-resource healthcare systems, yet empirical examination of facility-level leadership dynamics remains limited in low-income contexts. This study investigates the relationship between leadership styles, organizational culture, and staff performance across five healthcare facilities employing a sequential explanatory mixed-methods design. Quantitative surveys captured data from 372 healthcare workers, while 26 in-depth interviews provided contextual depth. Regression analyses demonstrated that transformational and participatory leadership styles significantly predicted enhanced teamwork, protocol adherence, and psychological safety (β = 0.42, p < 0.001), whereas authoritarian and laissez-faire approaches correlated with diminished organizational outcomes. Structural equation modelling revealed that organisational culture partially mediated these relationships, accounting for 38% of leadership's total effect. Qualitative findings illuminate how resource scarcity amplifies leadership influence, with supportive behaviours functioning as structural buffers against systemic constraints. The analysis indicates that leadership effectiveness is context-dependent and requires adaptive competencies that balance relational support with operational coordination. These findings underscore the necessity of embedding leadership development within health system strengthening initiatives, positioning relational leadership as essential infrastructure for quality care delivery in underserved settings.
