Healthcare organizations are very complex systems. Multidisciplinary personnel work as a team to improve patient care. Relational coordination, engagement with work, and employees who work proactively play a crucial role in promising efficiency and positive outcomes for an organization. Therefore, a descriptive correlational study was conducted to assess the level of relational coordination among head nurses, charge nurses, nursing administrators, and physicians, to assess the level of work engagement and proactive work behavior of head nurses, and to assess the correlation among relational coordination, work engagement and proactive work behavior of head nurses working in tertiary care hospitals of Punjab, Pakistan. 170 head nurses were selected by proportionate stratified random sampling technique. Self-administered Relational Coordination Scale, Utrecht Work Engagement Scale, and Proactive Work Behavior Scale were used to collect data. The results indicated statistically significant relational coordination among healthcare professionals. However, head nurses and charge nurses tend to have higher relational coordination scores than nurse administrators and physicians. The results also showed a significant correlation between the RC of head nurses with selected groups and their work engagement and proactive work behavior. The study highlighted that, when there is strong relational coordination among the multidisciplinary team, employees feel connected exhibit engagement with work, and act proactively to achieve organizational goals.
