Quality Improvement, Evidence-Based Practice and Research

Quality Improvement (QI) involves a systematic and continuous series of actions which result in measureable improvement in healthcare services and the overall status of health of groups of patients being targeted. QI involves four priciples of working through systems and processes and this means the resources or inputs to be used in the activities to be carried out or the processes that work to bring improvements in the quality of care as the outcome. The second pricniple is focusing on patients and knowing to what extent their needs and expectations are met (Kaplan, et. al., 2010). The third pricnciple of QI is focusig on team work and lastly, the focus on use of data in terms of telling how well the present systems are working. The process of QI involves setting aims or the objectives which should be SMART, establishing measures such as quantitative in determining whether specific changes lead to improvement, selcting changes which lead to improvement, amd testing the changes through planning, trying the changes, studying of observing the results and, lastly, acting on what is learned (Kaplan, et. al., 2010).

Evidence-Bases Practice (EBP) is the kind of practice that puts its reliance on scientific evidence in order to guide any decision making process. Patient values and their preferences as well as the expertize of the clinician are all important in any decisions made concerning the healthcare of the patient (Melnyk, et. al., 2014). Research on the other hand involves studies that aim at generating knowledge which is new or to validate one which is existing and this based on a theory. Research involves investigating, exploring and making discovery to get results which are only reliable and valid if a scientific method is used in the correct sequence (Holloway & Galvin, 2016). The differences between the three are highlighted below and in the middle of the figure is the similarity between the three.


Examples of QI, EBP and Research can be given as follows; an example QI project can be improving the processes patient education for a specific chronic disease. An EBP project can include evaluating an evidence based intervention to make improvements in wound healing. A research project example can be carrying out a systematic review of studies dealing with catheter-associated urinary tract infections (CAUTI). QI, EBP and Research would be applied in and health care setting because the act to complement each other. QI and EBP are complimentary in that EBP makes justifications on clinical decisions while QI puts EBP into practice and works to streamline the objectives of healthcare. Research also works to provide new ideas and knowledge on how healthcare can be improved.

QI, EBP and Research aim at achieving three goals an which are: promoting quality in a setting supporting professional practice, excellent service delivery to patients and disemmination of best practices in patient care services



QI uses systematic processes and actions to make improvements in patient outcomes



Research makes use of qualitative and quantitative research methodologies in development of new knowledge of how patients healthcare can be improved.



In Evidence-Based Practice (EBP) the best clinical evidence is sought and applied in making patient healthcare decisions
