hen we speak about "leaders," we all have thoughts about the competencies of a good leader. A person's ability to influence individuals and groups is one of several foundational pieces of being a leader. At the core of leadership is influence, the capacity to indirectly affect a thought, action, or outcome. 1 Dr. Eleanor Sullivan, a well-known nurse leader, suggests that influence is more important than having "authority" and can be bestowed just by the very nature of one's expertise. 2 A certain kind of leadership, thought leadership, has become somewhat of a buzz word in nursing. So, what is thought leadership and how does it integrate with being a leader and having influence? Or does it? Consider these three scenarios.1. Ashley is a newly hired certified ICU nurse. Ashley's unique expertise of working with families has gotten her noticed. Without realizing it, she showed her new peers how to care for families in crisis more effectively. 2. Justin is a creative thinker working in a cardiac surgery unit. He developed research to test the impact of daily pet visits on patient pain and anxiety. After a successful outcome, other units quickly adopted this newly established intervention. 3. Veronica, an adult NP, started a clinic to provide care to people who are uninsured and underinsured. She bypasses the complex middle step of insurance charging only $60 a visit no matter the healthcare issue. In addition, Veronica's clinic partners with other community services to provide free and/or reduced-cost services, such as nutrition counseling.
