BMC Nursing is calling for submissions to its Collection on diversity in nursing. The field of nursing is powered by a varied and dynamic workforce, yet it faces challenges recruiting and retaining nurses and administrative leaders who are truly representative of the populations they serve. As such, it is imperative that we deepen our understanding of diversity within the profession, including factors such as race, ethnicity, gender, age, culture, socioeconomic background, sexual orientation, and disability. Interdisciplinary research efforts have already yielded important insights, revealing, for instance, that racially and ethnically diverse nursing teams are associated with improved patient outcomes and increased patient satisfaction, especially with regard to underserved communities. As we continue to advance our understanding of diversity within nursing, we can anticipate innovations in patient-centered care models, more effective educational approaches, and equitable healthcare policies. By embracing the complexities of diversity, we hope to foster a nursing profession that is not only reflective of our diverse societies but also equipped to provide truly personalized and equitable healthcare.
