Societies have the potential to help achieve a significant reduction in the prevalence of the most common and costly behavioral and psychological problems that develop in childhood and adolescence—if they can implement evidence-based practices widely and effectively. Putting it more positively, we could assure that many more young people reach adulthood with the skills and interests needed to become productive and caring adults who contribute to the wellbeing of others (Biglan,2008).The impact of evidence-based practice (EBP) has echoed across nursing practice, education, and science. The call for evidence-based quality improvement and healthcare transformation underscores the need for redesigning care that is effective, safe, and efficient. In line with multiple direction-setting recommendations from national experts, nurses have responded to launch initiatives that maximize the valuable contributions that nurses have made, can make, and will make, to fully deliver on the promise of EBP. Such initiatives include practice adoption; education and curricular realignment; model and theory development; scientific engagement in the new fields of research; and development of a national research network to study improvement.

Public health nurses are part public health specialist and part healthcare provider. Their role is to improve the overall health of a larger population. To do this, they help develop, initiate, and manage public health programs, advocate for public health policies, educate the community on important health matters, and provide direct healthcare to individuals in need.


-When you’re trying to improve the health of a community, there’s a lot of room for new ideas and initiatives. Public health nurses often have the opportunity to come up with new methods of communication, new messages, and new programs designed to improve the community’s health. This makes community health nursing a great fit if you’re creative and enjoy developing new solutions.


-The disadvantage to this type of practice is it takes an extended period of time to gather data before it can be applied. Overall EBP is the best type of research for healthcare professionals.

-The disadvantage of the evolution of evidence based practice are the effects that evidence based practice has on lower income communities that have traditionally suffered from fewer resources, poor community health, and increased workload.

-In both rural and impoverished urban communities, health resources are often scarce. The community itself may lack funds and nonprofits and public health departments do not typically have expansive budgets. This can leave you facing a number of challenges as a pubic health nurse.

Evidence-based practice in nursing plays a vital role in enhancing the quality of health and care for the general wellbeing of the people. Reliability on evidence in nursing reduces mistakes in decision making for safety and quality healthcare practices. The use and nature of evidence-based practice have evolved over the years, indicating a vast difference and improvement. In your response, you have described the importance of evidence-based practices in nursing and the initiatives that have led to the advancement of evidence-based practice, such as practice adoption, nursing education, curriculum realignment, and scientific engagement. You could also have indicated how the use of evidence-based practise has evolved from the conception of the nursing profession to the current nursing. McMenamin et al. (2019) trace the history of evidence-based practice to Florence Nightingale’s time, who documented the interventions against the mortality rates associated with the diseases or chronic conditions to determine the effectiveness of the interventions. Nightingale’s model used observation as the primary source of evidence and not scientific researches. You can also note that the EBP evolved on introduction and formalization of nursing education, with theorists defining nursing as a collaborative and interpersonal process.

EBP in nursing was later transformed to focus on patient outcomes, primarily safety, quality and effectiveness. The healthcare systems gained a significant influence to adopt the best practices and policies for a sustainable practice called institutionalization. The founding of Cochrane Collaboration considered randomized controlled trials as a gold-standard source of highly objective evidence with minimum bias (McMenamin et al., 2019). The advantage of the evolution is that it improved the level and quality of care to the communities. You can also add that the educational evolution on the use of EBP improved the nurses’ abilities to advance in their role as researchers in nursing instead of leaving the responsibility to nurses who specialized in research. Every nurse can translate the data around them for an effective response to health issues. According to Falkenberg-Olson (2019), current nurses can carry out nursing practice research to advance the quality of care compared to earlier when nurses relied on a few.  Advanced nursing education provides a better opportunity to improve on the use of EBP in nursing.
