Organisational Culture and Healthcare Workforce Performance in Vietnam: The Mediating Roles of Knowledge Sharing and Digital Transformation

Background: Healthcare access in Vietnam confronts regional disparities and rising demand, requiring collaborative policies and strong workforce performance to guarantee effective and affordable services. This study scrutinises how organisational culture shapes healthcare workforce performance within Vietnam’s public healthcare organisations, with particular emphasis on organisational commitment, knowledge-sharing behaviour, and digital health transformation. Methods: This study employed a quantitative, cross-sectional survey design. Data were collected from 450 healthcare professionals in public healthcare facilities in southern Vietnam through convenience and snowball sampling, using a structured questionnaire measuring organisational culture (Denison model), organisational commitment, knowledge-sharing behaviour, digital health transformation and job performance on a six-point Likert scale. Data were analysed using partial least squares structural equation modelling (PLS-SEM) in SmartPLS 3.0. Results: The findings indicate that organisational culture is directly and substantively associated with healthcare workforce performance. In addition, knowledge sharing and digital health transformation operate as mediating mechanisms, with knowledge sharing showing a notably stronger indirect association. Notably, the relationship between organisational commitment and healthcare workforce performance was indicated to be not statistically significant. Conclusions: This study offers important practical and healthcare policy implications for healthcare administrators, human resource practitioners, public-sector leaders, and health policy stakeholders, predominantly in designing and employing targeted, culture-driven interventions aimed at improving healthcare workforce performance. Specifically, fostering a culture that encourages knowledge exchange and supports digital health transformation emerges as a critical pathway for organisational advancement. Such initiatives are instrumental in nurturing a motivated, engaged, and high-performing workforce, thereby underlining the sustainable development of public healthcare organisations.
