Introduction A research study described in the article “Educational Levels of Hospital Nurses and Surgical Patient Mortality” is observing the relation between the nursing staff education and the risk-adjusted mortality and failure to rescue cases. The essay is an evaluation of aforementioned study in terms of validity and findings’ implications. Problem Statement The problem statement of the study is the effect of the varied educational degree of nursing staff on patients’ outcome. In this context this statement is vital as it will determine the demand for the necessary educational level of the nurses for job application. Study Purpose The study purpose of this research is important as the effect of the nurses education is unknown on patients’ outcomes, thus it could possibly establish the direction for professional evaluation along with putting a certain measure of creditability of medical institutions based on staff’s educational level. Research Question(s) The research question is stated in the article as an examination on “whether the proportion of hospital RNs educated at the baccalaureate level or higher is associated with risk-adjusted mortality and failure to rescue “. There are other subside research questions that could be assumed through the study such as the effect of hospital characteristics on patients outcome and the relation between characteristics of surgical patients and the educational composition of staff registered nurses. Hypothesis The study hypothesis could be stated as the assumption that there is no possible effect of nursing staff’s educational level and the mortality percentage of patients. This hypothesis is the null hypothesis which states that there is no difference in the outcome. Therefore if proven wrong the alternative hypothesis must be true which could be stating that there is a difference in the mortality percentage based on nursing staff’s educational level. Study Variables As the independent variable is “the variable that is varied or manipulated by the researcher”, and the dependent variable is “the response that is measured.” the independent variables in the research are the highest credential in nursing, nurses’ workload and nurse experience. (Collier 2008) The dependant variables are deaths within 30 days of hospital admission and deaths within 30 days of admission among patients who experienced complications. Conceptual Model & Theoretical Framework The conceptual model used by the same author’s in their previous work “Hospital Nurse Staffing and Patient Mortality, Nurse Burnout, and Job Dissatisfaction” showed the variability of the educational degrees of nurses which provided an opportunity to conduct the present research. Review of Related Literature The review of previous studies showed that there is nothing known about the impact of nurses’ education on patient outcomes, and the few studies that have been conducted in the same field have inconclusive findings. Study Design The study design used is the non-experimental cross-sectional analysis which is “the one that takes place at a single point in time” and accordingly “taking a ‘slice’ or cross-section” in the population observed. (Web center 2006) As the study addresses the outcomes which take place even before collecting the data and the reliance mostly on the control variables, thus the stud
