Trusted interactions are crucial in health systems. Trust facilitates effective healthcare by encouraging patients to seek and adhere to treatment, enabling teamwork among health professionals, reducing miscommunication and medical errors, and fostering innovation and resilience. The COVID-19 pandemic underscored the importance of trust, highlighting the challenges in establishing and maintaining it, especially during crises when trust in authorities and health systems is vital for compliance and safety. However, trust is complex, varying with context and experiences, and is dynamic, easily lost but hard to regain. Despite its importance, trust is often overlooked in health policy and difficult to measure. Health systems and policymakers must recognize the importance of trust, measure it effectively, understand how it is built or eroded, and act to maintain and restore it. This involves acknowledging the past experiences of marginalized groups, involving communities in decision-making, and ensuring transparency and integrity in health practices and policies.
