The development, implementation, and evaluation of effective programs and policies is part of evidence-based public health practice. Also, the principles of scientific reasoning, use of systematic data, the use of information systems, program planning models, and the appropriate use of behavioral science theory is applied also within evidence-based public health practice (Department of Health & Human Services, 2010). Public health nursing is always evolving and there are always changes within clinical practices. How do public health nurses use available sources of evidence-based practice and apply them to keep up with the changes? A cross-sectional study was conducted to find what sources public health nurses utilized to gain knowledge for evidence-based clinical practice. The study showed that sources of knowledge used by public health nurses included national plans and guidelines, knowledge acquired while training as a public health nurse, personal experience, and guidelines and procedures issued by their local authorities (Weum et al., 2017). One source available to public health nurses (PHNs) is the Center for Disease Control and Prevention (CDC). The CDC is one of the major operating components of the Department of Health and Human Services that conducts critical science and provides health information to protect our nation (Centers for Disease Control and Prevention, 2021). Another available source to PHNs is the World Health Organization (WHO) their effort is also to promote healthy living and to help keep the world safe. Within both these organizations you can find health information, studies, treatments, online classes, and education materials to help become knowledgeable within public health practice.
