distinct well planned research period. The second study had a unique limitation in that it combined nurse staffing levels and two other variables: education and work environment (Cho 2015). As such, the mortality levels were based not only on nurse staffing but also the other two variables. The third study indicated a limitation because its conclusion lacked an evaluation of increasing nurse staffing ratio. Consequently, the study failed to provide evidence for the negative effect (formal cost) of increasing the staff on patient outcomes. 3
NURSE STAFFINGRecommendations for future researchIn future, research should be focused on the effect of nurse staffing on patients’ care quality and mortality rate. Nurse staffing should not be combined with other variables such as education and work conditions of the nurses. Precise concentration on the number of nurses would provide more accurate results. Also, the study should gauge the outcomes of staffing on two items: patients’ care quality and deaths during hospitalization. Previously, the studies did notcombine the two variables to reach a broader result. Care quality and mortality rate are critical elements of nursing as they dictate healthcare outcomes (Alqalawi, 2017). In the next research, one should observe the quality of life among the hospitalized to know whether it deteriorates or improved when staffing levels are high. Furthermore, mortality rate should be included to give insights into serious repercussions related to staffing levels.ConclusionThere is a correlation between the number of staff in a healthcare facility and the corresponding patient outcomes based on the literature review. Notably, the first study showed
