Introduction Healthcare organizations should be in a position to provide evidence-based medical support to patients from diverse backgrounds. International migration has transformed the demographics of many communities across the globe (Stetler, Ritchie, Rycroft-Malone, & Charns, 2014). This phenomenon challenges healthcare institutions to promote the concept of multidisciplinary teams. By so doing, such organizations can find it easier to provide culturally competent care to the targeted patients. However, many health professionals have failed to identify powerful management and leadership concepts that can be used to manage their multicultural healthcare organizations (Antwi & Kale, 2014). The proposed study, therefore, seeks to identify various management theories that can promote the organizational effectiveness of multicultural healthcare institutions. The study will go further to identify the most appropriate leadership traits necessary for leading multidisciplinary teams in an attempt to improve the level of service delivery. The completed research study will present new ideas and theories that can be embraced by multicultural healthcare organizations to drive performance. Statement of the Issue The issue of effectiveness in healthcare institutions is something that has been supported by many researchers and scholars. Successful hospitals are the ones capable of providing timely and evidence-based medical support to their clients. The changing global demographics have revolutionized how people receive medical support. Many health organizations are characterized by multidisciplinary teams. Such teams are composed of many professionals from different ethnic backgrounds. Similarly, such practitioners provide evidence-based care to patients from different ethnic, religious, and cultural backgrounds. This kind of complexity has made it impossible “for many healthcare institutions to make evidence-based practice a reality” (Stetler et al., 2014, p. 219). Some scholars in healthcare practice have gone further to explain how leadership can guide physicians and nurses to provide evidence-based care to their patients. There are various management strategies capable of producing positive results if applied adequately in different healthcare organizations. However, very little is understood or documented about the best leadership concepts that can promote the effectiveness of healthcare organizations. The above gap in healthcare leadership explains why modern scholars have been focusing on the best leadership traits that can support the performance of many multicultural hospitals. The leadership concepts and management traits presented by research findings can successfully support the effectiveness of many healthcare institutions. This proposed study is aimed at identifying suitable leadership and managerial traits that can be applied in multicultural healthcare organizations. The main objective is to identify the best leadership and management theories that can support the performance of multidisciplinary teams. The targeted models will ensure every multicultural healthcare institution provides evidence-based support to its clients. The completed study is expected
